  Methotrexate as an anticancer drug is hepatotoxic at high doses. It has been proven that oxidative stress is involved in methotrexate induced toxicity. Because of antioxidant potential of Brassica rapa. L root, this study was undertaken to examine the protective effect of hydroalcoholic extract of Brasscia rapa L. (BR) root  on methotrexate induced hepatotoxicity in the rat. For this purpose, forty male Wistar rats were randomly divided into four equal groups. Group 1 was used as control; groups 2 and 4 were orally treated with BR root extract (200 mg/kg) for 15 consecutive days. Groups 3 and 4 received a single intraperitoneal dose of methotrexate (20 mg/kg) on the 10th day of the experiment. At the end of the experiment, serumic levels of AST and ALT, ALP and total bilirubin, albumin and total proteins were assessed. Malondialdehyde and activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase were assayed in liver homogenates. Tissue sections were prepared from the liver and finally, the biochemical findings were compared with histopathological results. In group 4, BR root extract significantly (p<0.05) decreased the levels of serum biomarkers of hepatic injury and total bilirubin, and significantly increased the levels of serum albumin and total proteins (p<0.05). Also BR root extract significantly (p<0.05) decreased the lipid peroxidation and elevated the decreased values of hepatic antioxidants in this group. Histopathologic changes including degeneration, inflammation and necrosis were in agreement with biochemical findings. The results indicated that BR root extract, because of its antioxidant potential, exerts a protective effect against methotrexate induced hepatotoxicity in rats. Manuscript profile

  Carbamazepine is used as an anticonvulsant drug in the treatment of simple slight convulsion and generalized tonic-clonic, trigeminal neuralgia, and also as preventive agent in manic depressive. Carbamazepine reduces synaptic transmission by prolonging the inactivity of cellular sodium-potassium pump. Considering the clinical use of carbamazepine, the current study aimed to evaluate its cardiac effects in dogs. In this experimental-interventional study, fourteen native 1.5-2 years old female mixed breed dogs were procured and after laboratory testing and physical examination to ensure their general health status, they were divided into treatment and control groups (7 dogs in each group). On day zero, before drug administration, the electrocardiogram, echocardiogram and blood pressure was recorded. Both groups were maintained in the same conditions and carbamazepine was given orally to the treatment group for 7 days (with a dose of 8 mg/kg). After completing the administration period, the electrocardiogram, echocardiogram and blood pressure was obtained once again and the data were analyzed by one-way ANOVA. Blood pressure was significantly reduced in the treatment group (p < /em><0.05). Significant changes were also induced by carbamazepine in the dogs’ electrocardiogram and echocardiogram (p < /em><0.05). According to the results of the current study, it was found that carbamazepine could decrease blood pressure and induce notable alterations in the electrocardiogram and echocardiogram of dogs.

  Diabetes mellitus is a metabolic abnormality that has a relatively high prevalence all over the world. Kidney failure is one of the main complications of diabetes. Many therapeutic methods have been introduced from all over the world to treat diabetes. The aim of the present study was to assess the protective effect of Naringenin on early kidney injuries in alloxan-induced diabetic rats. Forty male Wistar rats were randomly allocated into 4 equal groups, including: healthy control, normal healthy receiving Naringenin, diabetic and diabetic receiving Naringenin. Diabetes was also induced by intraperitoneal injection of a single dose of naloxone (120 mg/kg). Naringenin treatment groups received the drug (50 mg/kg) daily for 3 weeks through the gavage. Finally, serum levels of kidney function markers including urea, uric acid and creatinine as well as amount of lipid peroxidation product (MDA) and activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and glutathione reductase (GR) were assessed in kidney hemogenates. Moreover, histopathological observation was assayed at the degree of renal injury. Significant differences among the groups were determined by one-way analysis of variance followed by Tukey post-test. Statistical significance was considered at p<0.05. In alloxanized diabetic rats, Naringenin significantly decreased the levels of serum urea, uric acid and creatinine (p<0.05), and significantly decreased the lipid peroxidation and elevated the levels of antioxidant enzymes in these rats (p<0.05). Histopathological changes were in agreement with biochemical findings. The results of the present study showed that naringenin with antioxidant properties can prevent early diabetic kidney damage.

  Abstract    Diabetes mellitus is a metabolic disorder and its incidence is considered to be high all over the world. Hepatic insufficiency is one of the most important consequences in this disease. A multitude of drugs has been described for the treatment of diabetes throughout the world. The aim of the present study was to assess the protective effect of Naringenin on early liver injury in alloxan-induced diabetic rats. Forty male Wistar rats were randomly assigned into 4 different groups of 10 rats each, including healthy control rats, normal healthy rats receiving Naringenin (50 mg/kg), diabetic rats and diabetic rats receiving Naringenin (50 mg/kg). Diabetes was induced with a single injection of alloxan (120 mg/kg i.p.). Naringenin groups received the drug daily for 3 weeks through gavage. At the end of the experiment, levels of liver function marker enzymes AST (Aspartate aminotransferase), ALT (Alanine aminotransferase) and ALP (Alkaline Phosphatase), TB (Total Bilirubin), Alb (Albumin) and TP (Total Proteins) were assessed in serum. Product of lipid peroxidation (Malondialdehyde; MDA), activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and glutathione reductase (GR) were also assayed in liver homogenate to evaluate antioxidant activity. Moreover, histopathological observations were made to assess the degree of hepatic injury. In alloxanized diabetic rats, Naringenin significantly decreased the levels of serum biomarkers of hepatic injury and TB, and elevated the levels of Alb and TP. Furthermore, Naringenin significantly decreased the lipid peroxidation and elevated the levels of antioxidant enzymes in these rats. Histopathological changes were in agreement with biochemical findings. The findings of this study indicated that Naringenin due to its antioxidant activities protects rats liver from early diabetic hepatopathy. Manuscript profile

     Drug therapy of cancer which is carried out by natural, synthetic or biological substances is associated with complications. Cisplatin as an anticancer drug, is hepatotoxic at high doses. Oxidative stress has been proven to be involved in cisplatin-induced toxicity. Because of antioxidant potential of resveratrol, this study was conducted to assess the protective effects of resveratrol, on cisplatin-induced hepatotoxicity in the rat. Forty male Wistar rats were randomly divided into four equal groups. Group 1 was used as control. For induction of hepatic injury in groups 2-4, cisplatin (3 mg/kg) was injected once every five days intraperitoneally. Groups 3 and 4 received silymarin (100 mg/kg) and resveratrol (20 mg/kg) respectively, daily for 4 weeks via intraperitoneal route. At the end of experiment, serum levels of aspartate and alanine transaminases, lactate dehydogenase and total bilirubin, albumin and total proteins were assessed. Malondialdehyde, reduced glutathione and activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase were assayed in liver homogenates. Finally, the biochemical findings were matched with histopathological verification. In group 4, resveratrol significantly (p<0.001) decreased the elevated levels of serum biomarkers of hepatic injury and total bilirubin, and significantly (p<0.001) increased the reduced levels of serum albumin and total proteins. In this group, resveratrol significantly (p<0.001) decreased the lipid peroxidation and elevated the decreased values of hepatic antioxidants. Histopathologically, the changes were in agreement with biochemical findings. The results obtained showed resveratrol, because of its anti-oxidant potential, exerts a protective effect against cisplatin induced hepatotoxicity in rats. Manuscript profile
