Peppermint plants have been used as a herbal medicine for many conditions, including loss of appetite, common cold, bronchitis, sinusitis, fever, nausea, vomiting and indigestion. This study is aimed at investigating the biochemical and histological effects of Mentha piperita L., growing in the Yenisar Bademli town of Isparta City, and Mentha spicata L., growing on the Anamas high plateau of Isparta City, on rat kidney tissue. Forty-eight male Wistar albino rats weighing 200-250 g were used for this study. Animals were divided into four experimental groups, each with 12 rats, as follows: control group (group I); 20 g/L M. piperita tea (group II); 20 g/L M. spicata tea (group III); 40 g/L M. spicata tea (group IV). The control group rats were given commercial drinking water (Hayat DANONESA water). The tea for the other groups was prepared daily and provided at all times to the rats during 30 days as drinking water. Plasma urea and creatinine levels were determined, and the levels of thiobarbituric acid reactive substance (TBARS) and the activities of glutathione peroxidase (GSH-Px), catalase (CAT) and superoxide dismutase (SOD) were studied in the homogenates of kidney tissue. The levels of plasma urea and creatinine were increased significantly (P < 0.0033) in groups III and IV when compared with group I. The activities of SOD and GSH-Px were decreased significantly (P < 0.0033) in group IV when compared with group I. The activities of CAT were decreased significantly in groups III and IV (P < 0.033, P < 0.0033, respectively) when compared with group I. TBARS levels were increased significantly (P < 0.0033) in groups III and IV when compared with group I. In groups II, III and IV, hydropic degeneration of tubular epithelial cells, the epithelial cells with picnotic nuclei and eosinophilic cytoplasm, tubular dilatation and enlargements in Bowman capsules were observed histologically. However, in group II histopathological changes were more slight than in groups III and IV. In group IV, in addition to these changes, extremely hydropic degeneration of tubular epithelial cells, some atrophic tubules and glomerules, and focal mononuclear cell infiltrations in the kidney tissues of the rats were observed. In conclusion, the results indicate that M. piperita does not show nephrotoxicity but M. spicata presents markedly nephrotoxic changes in rats.

The plant Mentha piperita, or peppermint, is commonly used in the treatment of loss of appetite, common cold, bronchitis, sinusitis, fever, nausea and vomiting, and indigestion as a herbal agent. In this study, we aimed to investigate biochemical and histological effects of M. piperita Labiatae, growing in the Yenisar Bademli town of Isparta city, and Mentha spicata Labiatae, growing in the Anamas high plateau of the Yenisar Bademli town, on the rat liver tissue. Forty-eight male Wistar albino rats weighing 200-250 g were used for this study. Rats were divided into four groups of 12 animals: Group I received no herbal tea (control group); Group II received 20 g/L M. piperita tea; Group III received 20 g/L M. spicata tea; and Group IV received 40 g/L M. spicata tea. Herbal teas were prepared daily and provided at all times to the rats during 30 days as drinking water. Liver function tests, including aspartate aminotransferase (AST/GOT) and alanine aminotransferase (ALT/GPT) activities were measured. To evaluate liver antioxidant defences, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and thiobarbituric acid reactive substance (TBARS) activities were determined in the homogenates of liver tissue. In addition, liver tissues were submitted for histopathologic examination. AST and ALT activities were increased in Group II, Group III and Group IV gradually when compared with the control group. The difference between Group II and the control group was not statistically significant (P > 0.016). Increases in AST and ALT activities of Group III and Group IV were statistically significant when compared with the control group. SOD, GSH-Px and CAT activities were increased in Group II when compared with the control group but the difference was not statistically significant (P > 0.016). However, SOD, GSH-Px activities and the TBARS level were significantly increased, and CAT activity was significantly decreased in Group III when compared with the control group. In Group IV, while SOD, GSH-Px and CAT activities were decreased, the TBARS level was increased as compared with the control group (P < 0.0016). Histopathological evaluation of experimental groups revealed a mild to severe degree of hepatic damage when compared to the control group. In Group II, there was only minimal hepatocytes degeneration. In Groups III and IV, there were granular or ballooning hepatocyte degeneration and necrosis, sinusoidal and central vein dilatation. It was concluded that lipid peroxidation and hepatic damage occurs after M. piperita and M. spicata administration in rat liver and the damage seems to be dose dependent.

Pongamia pinnata has been advocated in Ayurveda for the treatment of various inflammatory conditions and dyspepsia. The present work includes initial phytochemical screening and study of ulcer protective and healing effects of methanolic extract of seeds of P. pinnata (PPSM) in rats. Phytochemical tests indicated the presence of flavonoids in PPSM. PPSM when administered orally (po) showed dose-dependent (12.5-50 mg/kg for 5 days) ulcer protective effects against gastric ulcer induced by 2 h cold restraint stress. Optimal effective dose of PPSM (25 mg/kg) showed antiulcerogenic activity against acute gastric ulcers (GU) induced by pylorus ligation and aspirin and duodenal ulcer induced by cysteamine but not against ethanol-induced GU. It healed chronic gastric ulcer induced by acetic acid when given for 5 and 10 days. Further, its effects were studied on various parameters of gastric offensive acid-pepsin secretion, lipid peroxidation (LPO) and nitric oxide (NO) and defensive mucosal factors like mucin secretion and mucosal cell shedding, glycoproteins, proliferation and antioxidants; catalase (CAT), superoxide dismutase (SOD) and glutathione (GSH) levels. PPSM tended to decrease acid output and increased mucin secretion and mucosal glycoproteins, while it decreased gastric mucosal cell shedding without any effect on cell proliferation. PPSM significantly reversed the increase in gastric mucosal LPO, NO and SOD levels caused by CRS near to the normal level while it tended to increase CAT and GSH level decreased by CRS and ethanol respectively. Thus, the ulcer protective effects of PPSM may be attributed to the presence of flavonoids and the actions may be due to its effects both on mucosal offensive and defensive factors.

Myotonic dystrophy type 1 (DM1) is the most common form of muscular dystrophy affecting adults and is due to trinucleotide sequence (CTG) in the 3' UTR region of DMPK gene located at 19q13.3 chromosome. The pathogenic mechanisms of multisystemic involvement of DM1 are still unclear. The increased levels of reactive oxygen species/free radicals and lipid peroxides and decreased antioxidant levels play an important role in the pathogenesis of DM1. Present study includes 20 DM1 patients and 40 age- and sex-matched controls. Malonilaldehyde (MDA), superoxide dismutase (SOD), glutathione peroxidise (GPX), glutathione-S-transferase (GST), reduced glutathione (GSH), and TAS levels were measured and its association with clinical phenotype were evaluated. Results revealed significantly higher levels of MDA (p = 0.002), SOD (p = 0.006), and TAS p = 0.004) and lower level of GPX (p = 0.003), GST (P < 0.001) and GSH (P = 0.016) in DM1 patients. A significant negative correlation of MDA level with dyspepsia and CK-MB and GST level with serum SCK, CK-MB, and diabetes were observed. However, a significant positive correlation of SOD level with serum CK-MB, CK-MM, and diabetes and negative correlation with facial weakness were noted. Though, GSH level had significant positive correlation with learning and writing disability, speech, and languages disability yet found negative correlation with duration of disease. The GPX and TAS showed no correlation with any clinical findings. Our data further support the pathogenic role of oxidative stress in DM1 of Indian origin and support the opportunity to undertake clinical trials with antioxidants in this disorder.

Alpinia oxyphylla Miq. (A. oxyphylla), as a kind of medicine which also be used as food, is widely used in East Asian for the treatment of dyspepsia, diarrhea, abdominal pain and deficiency cold of spleen and stomach. This study aimed to investigate the protective effects of ethanol extract (EE) and its dichloromethane fraction (DM) of A. oxyphylla, which are rich in phenolic compounds, against CCl4-induced hepatic injury in vitro and in vivo. EE, DM and silymarin ameliorated CCl4-induced decrease of cell viability and increase of reactive oxygen species (ROS) in HepG2 cells. The CCl4-induced changes of glutathione (GSH) and methane dicarboxylic aldehyde (MDA) levels, and the decrease of superoxide dismutase (SOD) and catalase (CAT) activities were all restored with the pretreatment of EE, DM and silymarin. The results in liver injury model in rats showed that EE, DM and silymarin could significant decrease the levels of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and total bilirubin than the model group. Liver histopathology revealed that EE and DM attenuated the incidence of liver lesions triggered by CCl4 intoxication. They also effectively relieved CCl4-induced oxidative damage. Western blot analysis indicated NF-E2-related factor (Nrf2) pathway played an critical role in the protection of EE and DM against CCl4-induced oxidative stress. In conclusion, the extracts from A. oxyphylla might be used as hepatoprotective agents.
