Öğe Comparison of tru-cut biopsy and fine-needle aspiration cytology in an experimental alcoholic liver disease model(Assoc Medica Brasileira, 2020) Adali, Yasemen; Eroglu, Huseyin Avni; Makav, Mustafa; Karayol, Sunay Sibel; Guvendi, Gulname Findik; Gok, MustafaINTRODUCTION: Liver biopsies such as tru-cut (sharp needle) and fine-needle aspiration cytology (FNAC) are the most commonly preferred techniques to detect the grade and stage of certain liver diseases. In this study, we aimed to compare the efficiency of USG-guided tru-cut biopsy and fine-needle aspiration cytology in an experimental alcoholic liver disease model. METHODS: Thirty-six female Wistar albino rats, 4-6 months old, and weighing from 190 to 250 g, were used in this study. The animals were randomly divided into six equal groups: GI (control), G2 (tru-cut control), G3 (FNAC control), G4 (Alcoholic liver disease model), G5 (Alcoholic liver disease model + FNAC), and G6 (Alcoholic liver disease model + tru-cut biopsy). After a histopathological evaluation by light microscopy, the sensitivity, specificity, positive and negative predictive values of FNAC and tru-cut biopsy for the diagnosis of liver lesions were calculated. RESULTS: No pathology was detected in GI except for mild congestion. On the other hand, hepatocyte damage, periportal inflammation, congestion, and fatty changes were detected in all liver tissues of the alcoholic liver disease groups. The sensitivity of hepatocyte damage, inflammation, congestion, and fatty change parameters for FNAC were 33.3%, 80%, 0%, and 0%, respectively, while the sensitivity of the same variables for tru-cut were 66.7%, 40%, 100%, and 20%, respectively. DISCUSSION: Both techniques were superior in some aspects. FNAC can be an attractive alternative to tru-cut biopsy and applied in routine practice in the diagnosis of non-tumoral liver diseases.Öğe Effect of sainfoin (Onobrychis viciifolia Scop.) seed-based diet on rats: A comprehensive evaluation of hemogram, biochemistry, and histopathology(Wiley, 2024) Craine, Evan B.; Makav, Mustafa; Dag, Serpil; Yildiz, Ayfer; Eroglu, Huseyin Avni; Kuru, Buket Boga; Bektasoglu, FikretSainfoin species (Onobrychis spp.) have been employed for centuries as an essential forage for ruminant animals, both for grazing and as hay. The seeds produced by sainfoin have also been investigated as an animal feed source and were indicated to be a particularly protein-rich supplement for monogastric animals. This study explores the effects of two sainfoin seed inclusion rates in rat diets compared to a control diet, focusing on blood biochemical parameters and a comprehensive histopathological evaluation of multiple organ systems. Thus, we provide a novel contribution to the body of evidence investigating sainfoin seeds as a protein supplement in monogastric animal diets. In this 21-day experiment, seven rats each were assigned to the control group, a 5% sainfoin seed group, and a 10% sainfoin seed group. The control group received standard feed and water; the second group received feed with 5% sainfoin seeds; and the third group received feed with 10% sainfoin seeds. At the experiment's end, necropsies and evaluations were conducted. Histopathological exams revealed normal organ structures in all 21 samples, regardless of the group. Blood analysis showed statistically significant decreases in creatine, ALT, P, Ca, and Mg levels in the sainfoin seed groups compared to the control group, with most values nearing reference levels, suggesting potential benefits. Notably, no adverse effects were observed when sainfoin seeds were included at 5% and 10% in the rat feed. These findings contribute to a growing body of research investigating the inclusion of sainfoin seeds in monogastric animal diets, which is a foundational component of assessing sainfoin's potential as a novel pulse crop for human consumption.Öğe Effects of hyperbaric oxygen treatment on liver and kidney tissue in chronic arsenic toxicity(Undersea & Hyperbaric Medical Soc Inc, 2022) Eroglu, Huseyin Avni; Buyuk, Basak; Oztopuz, Ozlem; Makav, Mustafa; Aydeger, CemreArsenic (As) is a toxic substance that damages the human body through exposure to drinking water. This exposure damages many organs and tissues in the body, especially the liver and kidneys. Hyperbaric oxygen (HBO2) therapy is a treatment method that acts by reducing oxidative stress parameters in tissues with high-pressure oxygen. Based on this, our study aimed to investigate the effectiveness of HBO2 on liver and kidney tissues with chronic arsenic toxicity. In the study 24 male Wistar albino rats (220-300 g, two to three months old) were equally divided into four groups: Control; As; HBO2; and As+ HBO2. All animals were housed in individual cages. The toxicity model was created by adding arsenic to drinking water at a dose of 5 mg/kg/ day for 60 days. HBO2 was applied 2 ATA pressure for 90 minutes a day for five days. At the end of the study, liver and kidney tissues were taken and stored for analysis. In liver tissue, histopathological showed that arsenic reduced inflammatory cell infiltration, sinusoidal congestion, and hydropic degeneration, while HBO2 increased these measures. Similar results were found by TUNEL method. In kidney tissue, both histopathologic and TUNEL method examinations found similar results with the liver: The As group was more damaged than the As+ HBO2 group.Öğe Effects of Ozone and L-Carnitine on Kidney MDA, GSH, and GSHPx Levels in Acetaminophen Toxicity(Kafkas Univ, Veteriner Fakultesi Dergisi, 2020) Eroglu, Huseyin Avni; Makav, Mustafa; Adali, Yasemen; Citil, MehmetThis study aimed to determine the therapeutic effects of medical ozone and L-carnitine therapy on acetaminophen (APAP)-induced kidney damage by evaluating malondialdehyde (MDA), glutathione (GSH), and GSHPx levels. In this study, 56 rats were randomized into 8 groups with 7 rats in each group. Kidney injury was induced by the administration of a single dose N-acetyl-p-aminophenol (1 g/kg) orally.Therapeutic ozone (0.7 mg/kg) and L-carnitine (500 mg/kg) were administered intraperitoneally. After the therapy, the rat kidneys were homogenized, and the tissue MDA, GSH, and GSHPx levels were measured. Compared to the control groups, there were higher MDA levels in the kidney tissues only in the APAP, APAP + Ozone, and APAP + Ozone + L-carnitine groups (P<0.001). Besides, the decrease in the GSH and GSHPx levels of the kidney tissues in the study groups were significant compared to the control groups, and the highest decreases were observed in the APAP APAP + Ozone and APAP + Ozone + L-carnitine groups (P<0.001). Findings obtained from this study revealed that acetaminophen toxicity caused oxidative damage in the examined kidney tissues, and L-carnitine and/ or ozone applications for protective purposes decreased MDA levels, a product of lipid peroxidation, and increased tissue GSH levels thru GSHPx antioxidant enzyme activity. In this context, the most important protective effect was observed in the group where L-carnitine and ozone were administrated together.Öğe Effects of Ozone Therapy on Chronic Arsenic Poisoning in Rats(Springer, 2023) Büyük, Başak; Aydeğer, Cemre; Öztopuz, Özlem; Ovalı, Mehmet Akif; Makav, Mustafa; Eroğlu, Hüseyin AvniArsenic (As) is a toxic metalloid that affects many organs through drinking water. This study aims to examine the efficacy of ozone therapy on chronic arsenic toxicity. Twenty-four male Wistar albino rats were housed in individual cages and grouped as control, As, O3, and As + O3. As was applied by adding 5 mg/kg/day in drinking water for 60 days. Ozone therapy was applied at 0.5 mg/kg/day (i.p.) O3 in the last 5 days of the experimental period. Tissues were harvested and analyzed for histopathological injury and apoptotic markers. There was no significant difference between the As + O3 and O3 groups (p = 0.186 and p = 0.599) for light microscopic criteria: inflammatory cell infiltration and hydropic degeneration in liver tissue. In TUNEL assessments, similar outcomes were obtained in the control and As + O3 groups. A statistically significant increase was observed in p53 and Caspase 3 (Casp-3) expression levels in the As group compared to the O3 and As + O3 groups. There was no significant difference between the As + O3 and O3 groups on peritubular hemorrhage and desquamation parameters in kidneys (p = 0.147 and p = 0.094). The KIM-1 expression level was significantly increased in the As group compared to the As + O3 group (p = 0.01), and the Casp-3 expression level was not significantly changed in the O3 group compared to the As + O3 group (p = 0.59). In conclusion, it is determined that ozone therapy has ameliorative effects on the microscopic injury of liver and kidney tissues. In addition to microscopic improvement, KIM-1 gene expression levels were ameliorated in the kidneys. The apoptotic cell counts and the Casp-3 and p53 gene expression levels were decreased by O3 administration. Thus, ozone therapy can be a treatment choice for As toxicity.Öğe Efficacy of Ozone and Selenium Therapy for Alcoholic Liver Injury: An Experimental Model(Int Inst Anticancer Research, 2019) Adali, Yasemen; Eroglu, Huseyin Avni; Makav, Mustafa; Guvendi, Gulname FindikBackground/Aim: Alcoholic liver disease is an important health problem which is reversible during early stages of liver damage, but becomes permanent with time. Nowadays, many studies focus on various agents that prevent, reduce or slow the progression of the toxic effects of alcohol. In our study, we investigated the efficiency of ozone and selenium against oxidative damage in a model of alcohol-induced liver damage. Materials and Methods: Forty-eight female Wistar Albino rats between 4 and 6 months of age and weighing 190-250 g were included in the study and were used as models of alcohol liver damage. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), serum and tissue total oxidant levels, serum and tissue total antioxidant levels, and the histopathological evaluation of the liver were performed in 8 groups. Results: In the statistical analysis, it was observed that ozone and/or selenium therapies decreased the AST levels. Total oxidant and antioxidant serum levels were found to vary in serum and tissue. Ozone and/or selenium therapies decreased liver damage, according to histopathological findings. Conclusion: Through ozone and/or selenium therapies, less damage was observed histopathologically compared to the alcohol group. It is thought that the results of our study can be used in individual treatments following confirmation of liver damage in alcoholic patients.Öğe Experimental intravaginal and intrauterine endometritis model: which model is more useful?(2022) Makav, Mustafa; Kuru, Mushap; Beşeren, Hatice; Adalı, Yasemen; Coşkun, Mustafa Reha; Eroğlu, Hüseyin AvniThis study aims to compare the newly created intravaginal endometritis model (IVM) with the intrauterine endometritis model (IUM). E. coli infusion was used as intravaginally for IVM and intrauterinally for IUM model. The animals were exeuted on the 7th day. Histopathological and biochemical analyses [malondialdehyde (MDA), glutathione (GSH), Endocan, Endoglin] were performed. A significant inflammation was determined in IVM and IUM compared to the control. A significant decrease in GSH and a significant increase in MDA and Endoglin were determined in IVM and IUM compared to the control. There was a statistically significant increase in the IUM and a numerical increase in the IVM compared to the control. Endometritis was determined by histopathological and biochemical analyses in both IUM and IVM model. It is suggested that intravaginal administration, which is easier to perform, can be used in experimental endometritis model studies.Öğe Fine Needle Aspiration Cytology (FNAC) vs. Tru-cut Biopsy in Liver with Iron Overload: An Experimental Study(2023) Adalı, Yasemen; Eroğlu, Hüseyin Avni; Makav, Mustafa; Karayol, Sunay Sibel; Güvendi, Gülname Fındık; Gök, MustafaObjective: Fine needle aspiration cytology (FNAC) is safer, simpler, faster and cost effective, compared to tru-cut biopsy, and patient compliance is generally better. There is not much data on the use of FNAC, which is used in many organs and lesions, in parenchymal diseases in the liver. Therefore, in this study, the benefit of FNAC in showing iron deposition and injury of liver is evaluated. Methods: There were 2 control groups in the study. At the end of the study, FNAC and tru-cut biopsy samples were taken from these groups, where no administration was performed. FNAC and tru-cut biopsy procedures were also performed to the study groups after the iron overload was created by intraperitoneal iron dextran (88 mg/kg) administration for 28 days. Hepatocyte injury, inflammation and iron deposition were evaluated histopathologically in the preparations. The sensitivity, specificity, positive and negative predictivity and diagnostic accuracy of both methods were calculated based on the hepatectomy material. Results: In hepatocyte injury; sensitivity (60%), diagnostic accuracy (66.7%) and negative predictivity (50%) were found to be significantly higher in tru-cut group. It was observed that the methods were not superior to each other in the evaluation of inflammation, and FNAC almost approached tru-cut biopsy rates (100%) with a sensitivity of 83.3% and diagnostic accuracy in iron deposition. Conclusion: In iron-induced liver damage, the gold standard should be tissue examination, so tru-cut biopsy must be the first choice. However, based on the present study results, it is suggested that FNAC may be preferred over more invasive options in cases where tru-cut biopsy can not be used in terms of susceptibility to bleeding, situations where surgical accessibility is not available, patient orientation and cooperation is poor, or in presence of different accompanying diseases.Öğe Investigation of Lycium barbarum Effects on Ovarium Damage Exposed to N-Methyl-N-Nitrourea(Springer, 2025) Eroglu, Hueseyin Avni; Buyuk, Basak; Aydeger, Cemre; Demir, Ufuk; Makav, MustafaN-Methyl-N-nitrourea (MNU), is one of the N-nitroso compounds that people are commonly exposed to in various exogenous ways such as diet, tobacco smoke, cosmetics, household goods, indoor air, occupational exposure, etc. It is known that the compound damages organs and tissues in the body, and one of the affected structures is the ovarium. Lycium barbarum, used in medication in ancient China, has become more popular in recent years. Previous studies have mentioned that polysaccharide ingredients are the most bioactive parts of Lycium barbarum. Therefore, this study aims to investigate the effects of Lycium barbarum polysaccharides (LBP) on ovarian tissue damage exposed to MNU. In accordance with this purpose, a total of 12 21-day-old female Wistar Albino rats were divided into two groups: sham and treatment. The animals were administrated with 50 mg/kg MNU (i.p.) on days 21, 28, 35, and 42. The treatment group was treated with 800 mg/kg LBP via intragastric for 30 days. At the end of the study, animals were sacrificed under general anaesthesia, and the ovarian tissues were harvested. Shrinkage of follicles, lytic oocytes, and disintegrated stroma parameters were evaluated histopathologically. The genetic assessment of the Bcl-2, Bax, Bcl-2/Bax ratio, Caspase 3, p53, and p27 expression levels were determined. The histopathological parameters between the groups were statistically significant (for all parameters p < 0.001). Moreover, the Bcl-2, Bcl-2/Bax ratio, and p53 relative fold changes were significantly increased in the treatment group (p < 0.001, p = 0.045, and p = 0.011, respectively). The results revealed that LBP has ameliorative effects on MNU-induced ovarian tissue damage. Further studies are required to clarify the main underlying mechanisms.Öğe Investigation of the Effects of Dimethyl Sulfoxide in Experimental Gout with Comparison of Dexamethasone and Indomethacin(Springer, 2024) Aydeger, Cemre; Adali, Yasemen; Makav, Mustafa; Eroglu, Hueseyin AvniGout arthritis is an inflammatory arthritis characterized by increased serum uric acid and accumulation of monosodium urate (MSU) crystals in soft tissues. The treatment for gout arthritis is centered on reducing uric acid agents with long-term and anti-inflammatory agents during attack times. In recent studies, it is noteworthy that Indomethacin and Dexamethasone have positive effects in the treatment of gout. Dimethyl sulfoxide (DMSO) is a lipophilic solvent and has an anti-inflammatory effect at appropriate doses. Based on this information, for this study, the effects of these three agents were investigated in rats using a gut model to compare their efficacy. In the study, a total of 48 female 3-4-month rats were divided equally into 8 groups: Control, Indomethacin, DMSO, Dexamethasone, Gout, Gout+Indomethacin, Gout+DMSO, Gout +Dexamethasone. During the eight-week study, a gout arthritis model was used that included 10 mg MSU given intra-articularly in the right foot. Indomethacin 12.5 mg/kg intragastric, DMSO 0.1 ml intraperitoneally and dexamethasone 0.2 mg/kg were administered subcutaneously to the related groups once a day for seven days. At the end of the study, collected articular tissues were stained with haematoxylin and eosin after the fixation and decalcification processes were done. The findings obtained showed that inflammation was reduced in treatment groups compared to the Control groups (all p values 0.002). Also, synovial proliferation was remarkably decreased in the Gout+Dexamethasone group compared to the Gout group (p = 0.019). As a result of these findings, although the three agents all reduced inflammation in gout arthritis, DMSO was shown to be more advantageous due to its having fewer side-effects.Öğe Ozone vs Melatonin: The Therapeutic Effects In Alcoholic Liver Disease(2020) Eroğlu, Hüseyin Avni; Makav, Mustafa; Güvend, Gülname Fındık; Büyük, Başak; Adalı, YasemenBackground: Alcoholic liver disease (ALD) is a worldwide health problem.Ozone and melatonin areagents that are widely used for their antioxidant properties in medical therapies.In this study, we aimedto evaluate the use of ozone and melatoninin ALD.Materials and Methods: Forty-eight rats were used, and ethanol, melatonin, and ozone wereadministrated. Histopathological evaluation was performed and activities of alanine aminotransferase(ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT) total antioxidant status(TAS), total oxidant status (TOS), and malondialdehyde (MDA)were determined in the blood samples,while TAS, TOS, and MDA parameters were measured in the liver tissue samples.Results: There were statistically significant differences between the studied groups concerning ALT,AST activities and TAS, TOS, and MDA levels. Vascular congestion, hepatocyte damage, periportalinflammation, and microvesicular steatosis were detected inthe alcohol-induced toxicity group.Conclusions: In the light of histopathological findings, we can claim that melatonin and ozoneadministrations are beneficial for alcohol-induced hepatotoxicity. However, ozone application issuperior to melatonin.Öğe Protective Effects of Melatonin against Chronic Sodium Nitrite Exposure in Rats(2019) Uslu, Hamit; Uslu, Gözde Atila; Adalı, Yasemen; Makav, Mustafa; Gelen, VolkanIn this study, anti-inflammatory effects melatonin (Mel) on liver and kidney damage induced by sodium nitrite (NaNO2) used as a food additive were investigated. The study groups were control group (C), NaNO2 group (NaNO2) and melatonin + NaNO2 group (Mel + NaNO2). The first group received dimethyl sulfoxide (DMSO) and the second and third groups received NaNO2 orally for twelve weeks. The third group received melatonin 2 hours before the administration of NaNO2. Administration of NaNO2 (80 mg/kg/day) for 12 weeks orally to rats increased serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) (P<0.001) and urea (P<0.01) levels. Interleukin 1-alpha (IL-1?) (P<0.05) and tumor necrosis factor alpha (TNF-?) (P<0.01, P<0.001 respectively) levels were found to be increased in NaNO2 group in liver and kidney homogenates. It was also determined that IL-6 (P<0.001) levels were increased in kidney tissue. On the other hand, it was also found that there was a decrease at the levels of serum AST (P<0.001), ALT, urea (P<0.05), liver IL-1?, TNF-? (P<0.01), and kidney TNF-?, IL-6 (P<0.05) in group given melatonin (500 ?g/kg/day) 2 hours before NaNO2. In addition, it was observed that there was less liver and kidney damage than NaNO2 group in the pathological examinations Mel + NaNO2 applied group. The present data demonstrate that melatonin administration has visible modulatory effects and can eliminate inflammation; moreover, it can prevent the increase in biochemical markers caused by chronic sodium nitrite administrationÖğe Recuperative effect of estrogen on rotenone-induced experimental model of Parkinson’s disease in rats(Springer, 2021) Makav, Mustafa; Eroğlu, Hüseyin AvniParkinson’s disease (PD) is described as the loss of dopaminergic neurons located in the substantia nigra (SN) region of the brain and a progressive motor failure. Increased frequency of PD in women, especially after menopause, suggests the effect of estrogen. This view has been supported with empirical studies. Therefore, the effect of estrogen in an experimental model of Parkinson’s disease induced by rotenone was investigated. A total of 32 female Wistar Albino rats were randomly assigned to four groups (control group, ovariectomy group, Parkinson’s group, Parkinson’s + estrogen group). The Parkinson’s group received rotenone subcutanously at the dose of 2.5 mg/kg bw, on the 1st, 2nd, 3rd 4th, 6th, 9th, 12th, 15th, 18th, and 21st days animals in the Parkinson’s + estrogen group received retonon as in the Parkinson’s group and was additionally subcutaneously given estrogen (implant containing 0.5 mg 17 β-estradiol lasting for 21 days). The rats were subjected to rotarod, pole, and swimming tests at the end of the experiment for comparison of their motor activities, and then, histopathological and biochemical analyses were performed on the tissues that were extracted. The rotarod results revealed that Parkinson’s group had the shortest time (32.33 ± 3.98 sn) than the groups of control (92.50 ± 12.60 s) ovariectomy (71.42 ± 10.58 s), and Parkinson’s + estrogen (71.37 ± 9.26 s). The results of pole disclosed that return and landing time prolonged for Parkinson’s group when compared with other groups (return time for control 2.98 ± 0.38 s, ovariectomy 3.02 ± 0.75 s, Parkinson 5.91 ± 0.33 s, Parkinson’s + estrogen 3.48 ± 0.42 s and landing time for control 5.30 ± 0.59 s, ovariectomy 5.45 ± 0.73 s, Parkinson 9.80 ± 0.90 s, Parkinson’s + estrogen 5.37 ± 1.02 s). Parkinson’s group had longest (90.71 ± 12.56 s) swimming time to reach the target when compared with control (33.16 ± 8.68 s), ovariectomy (47.37 ± 12.19 s), and Parkinson’s + estrogen (49.82 ± 5.78 s). Histopathological examination indicated a significant difference in tyrosine hydroxylase-stained cells (dopaminergic neurons and dopamine) between the Parkinson’s + estrogen group and the Parkinson’s group. The biochemical analyses of Caspas-3 activation in SN and striatum (STR) was significantly different between the Parkinson’s + estrogen group and the Parkinson’s group, but this difference was not observed in STR while evaluating Bcl-2. The results of this study suggested that estrogen may have a recuperative effect on PD.Öğe Selenium or ozone: Effects on liver injury caused by experimental iron overload(Pergamon-Elsevier Science Ltd, 2020) Guevendi, Guelname Frndrk; Eroglu, Hueseyin Avni; Makav, Mustafa; Guvendi, Buelent; Adalre, YasemenAims: Iron is an important metal ion as a biocatalyst on the other hand iron overload causes various diseases. Iron overload can result in fibrosis and hepatocellular carcinoma with various pathophysiological mechanisms, including oxidative damage in the liver. Therefore; in this study the effects of ozone and selenium-whose antioxidant properties are known- were evaluated in liver injury induced by iron overload. Materials and methods: Iron overload model was provided by intraperitoneal administration of 88 mg/kg iron dextrate for 4 weeks. After iron dextran administration, ozone and selenium administrations were made for 3 weeks. From the obtained blood and tissue samples total oxidant status (TOS) and total antioxidant status (TAS) were determined and histopathological examination was performed in liver tissue samples. Key findings: In rats with iron overload, the lowest mean serum TOS was observed in the selenium administration group. The highest tissue TOS means and the lowest tissue TAS means were determined in the group in which ozone and selenium were administrated together. When histopathological data were evaluated, the presence of increased apoptosis in the ozone group compared to the iron group (p = 0.019) and selenium group (p= 0.019) was noted. Similarly, increased periportal inflammation (p = 0.001) and fibrosis (p = 0.005) were observed in the ozone group compared to the selenium group. Significance: In iron-induced liver damage, ozone was thought to be effective by decreasing ROS, but contrary to expectations, it was observed that it may negatively affect the picture by showing synergistic effect. However, the effects of selenium on both serum and tissue levels are promising.Öğe The Effect of Turkish Coffee on Performance, Biochemical, and Physiological Parameters in Rabbits(2021) Makav, Mustafa; Ölmez, Mükremin; Eroğlu, Hüseyin Avni; Şahin, TarkanCoffee is one of the most widely consumed hot beverages in the world. Melanoidins, which are formed with brown color during coffee roasting, are reported to be a strong antioxidant. Discussions related to the more and less consumption of coffee still continue. This study investigated the effect of a low and high amount of coffee consumption on antioxidant parameters in this context. A total of 15 female New Zealand rabbits weighing 1500-2500 g were used in the study. The control group was fed as ad-libitum control with basal feed. 1% and 5% Turkish coffee were added to the feed of the 1% TC and 5% TC groups, respectively. Blood was collected once a week throughout the study. All animals were euthanized in accordance with ethical rules at the end of the study. Samples (plasma and tissue) were taken for the analyses. Glutathione (GSH) and malondialdehyde (MDA) analyses were performed on all samples. Plasma GSH values were observed to increase in the groups given TC according to the analyses. Plasma MDA values decreased in the TC groups. An increase was observed in liver and heart tissue in the TC group upon the evaluation of tissue GSH parameters. MDA values were found to decrease in lung, heart, and kidney tissues in TC groups. Additional effects were observed in plasma and tissues in the 5% TC group upon the evaluation of 1% TC and 5% TC groups. No statistical differences were found in performance parameters. It has been revealed as a result that TC is a strong antioxidant, and its effect increases in high consumption.Öğe The Investigation of the Effect of Ozone Therapy on Gout in Experimental Rat Models(Kafkas Univ, Veteriner Fakultesi Dergisi, 2019) Bilge, Ali; Tuysuz, Murat; Ozturk, Omur; Adali, Yasemen; Eroglu, Huseyin Avni; Makav, Mustafa; Atilla Uslu, GozdeThe effect of ozone treatment in experimental rat gout arthritis was investigated. Twenty adult albino male rats were divided into 4 groups: Group 1 (Control) was followed without any medication, Group 2 (Gout control) was injected with a single dose of 0.2 mL (10 mg) monosodium urate (MSU) intraarticulary to 1st metatarsophalangeal joint to create experimental Gouty arthritis. Group 3 (Gout + Ozone) was injected intraarticulary to 1st metatarsophalangeal joint with a single dose of 0.2 mL (10 mg) MSU to generate experimental gout, followed by ozone therapy to the rats a single dose of 1 mL (10 mu g/mL) intraperitoneally daily for 3 weeks. The Group 4 (Ozone control) ozone therapy was given a single dose of 1 mL (10 mu g/mL) intraperitoneally daily for 3 weeks without gout formation. The results were recorded and compared statistically between the groups. In conclusion, the low level of inflammation in the third group (Gout + Ozone) was considered statistically significant as compared to the second group. With Ozone treatment the gout joint has been shown to have reduced acute inflammation, it has not been affected by the chronic proliferation process.Öğe Therapeutic effect of Tarantula cubensis extract on indomethacin induced gastric ulcers in rats(Chulalongkorn Univ, 2020) Makav, Mustafa; Gelen, Volkan; Gedikli, Semin; Atila Uslu, Gozde; Uslu, Hamit; Eroglu, Huseyin AvniNon-steroid anti-inflammatory drugs (NSAIDs) have widely been used in patients but side-effects associated with NSAID are also common. Tarantula cubensis extract (TCE) is an antiphlogistic, demarcative, homeopathic and necrotizing drug with wound healing effects in farm animals. However, the therapeutic effects of TCE on gastric ulcers has not been investigated. The aim of this study was to investigate the gastroprotective effects of TCE against indomethacin-induced gastric injury in rats. A total of 28 female, Wistar albino rats were divided into four groups: (i) the control group, (ii) the indomethacin (Indo) group, (iii) the TCE + Indo group, and (iv) the ranitidine + Indo group. We measured total antioxidant capacity, total oxidant capacity and oxidative stress index in the blood serum. We also measured tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), IL-6, IL-8, and cyclooxygenase-2 (COX-2) activity level in the stomach tissue of rats. Finally, histopathology of the tissue of all groups was assessed. Immunostaining of 8-hydroxydeoxyguanosine (8-OHdG) and nuclear factor kappa B (NF-kB) was performed in the gastric tissue of all animals studied. Application of the TCE significantly decreased IL-1 beta and IL-6 levels were markedly lower than ranitidine. Thus, notable Indo-induced alterations in cytokines (IL-1 beta, IL-6) in rat gastric tissue were alleviated by TCE. Moreover, the gastric mucosal tissues of the TCE treated group exhibited a regular and uninterrupted mucosal layer and epithelial layer. Immunohistochemical results revealed that Indo increased 8-OHdG and NF-kB expression when compared to the control groups and treatment by TCE decreased the expression. The results obtained showed that the group receiving TCE exhibited lower gastric erosion and better efficiency than with ranitidine. These results have demonstrated that TCE provides a therapeutic effect in Indo-induced gastric ulcers in rats.
