    Methotrexate (MTX) is a widely used antiarthritic and chemotherapeutic agent known to cause damage to various tissues. This study investigated the potential protective effects of parsley extract against MTX-induced brain and intestinal tissue damage. Sprague-Dawley rats were divided into control, control + parsley, MTX, and MTX + parsley. MTX (20 mg/kg, i.p.) was administered to the MTX and MTX + parsley groups. The control + parsley, and MTX + parsley groups were administered 2 g/kg parsley extract by oral gavage for five consecutive days. After the fifth day, brain and small intestinal tissues were taken. Total protein, nitric oxide, lipid peroxidation, glutathione levels, tissue factor, superoxide dismutase, and glutathione S-transferase activities were determined in these tissues. The protein profiles of the tissues were evaluated using SDS polyacrylamide gel electrophoresis. Parsley administration caused a decrease in lipid peroxidation levels in both tissues of the MTX group. On the other hand, glutathione level, glutathione-S-transferase, and superoxide dismutase activities were found to be increased. On the other hand, parsley decreased the nitric oxide level which was increased in the intestinal tissues of the MTX group. There was no significant change in brain nitric oxide level and tissue factor activity between groups. MTX and parsley administration altered protein expression, leading to the appearance or disappearance of specific bands in intestinal and brain tissues. In conclusion, parsley alleviated MTX-induced damage in brain and intestinal tissues by reducing lipid peroxidation and modulating antioxidant defenses.

    Investigation of Possible Neuroprotective Effects of Some Plant Extracts on Brain in Bile Duct Ligated Rats

    This study aimed to investigate the possible neuroprotective effects of bitter melon (BM), chard, and parsley extracts on oxidative damage that may occur in the brain of rats with bile duct ligation (BDL)-induced biliary cirrhosis. It was observed that lipid peroxidation (LPO), sialic acid (SA), and nitric oxide (NO) levels increased; glutathione (GSH) levels, catalase (CAT) activity, and tissue factor (TF) activity decreased significantly in the BDL group. However, in groups with BDL given BM, chard, and parsley extracts LPO, SA, NO levels decreased; GSH levels and CAT activities increased significantly. No significant differences were observed between groups in total protein, glutathione-S-transferase, superoxide dismutase, and boron. Histological findings were supported by the biochemical results. BM, chard, and parsley extracts were effective in the regression of oxidant damage caused by cirrhosis in the brain tissues. Practical applications Bitter melon (BM), chard, and parsley have antioxidant properties due to their bioactive compounds which are involved in scavenging free radicals, suppressing their production, and stimulating the production of endogenous antioxidant compounds. Since BM, chard, and parsley extracts were found to be effective in the regression of oxidant damage caused by cirrhosis in the brain tissues, these plant extracts may be an alternative in the development of different treatment approaches against brain damage in cirrhosis. At the same time, these species have been used as food by the people for many years. Therefore, they can be used safely as neuroprotective agents in treatment.
