The effect of ethanol (0.5 and 1.0 g/kg) on gastrointestinal absorption and presystemic biotransformation of propoxyphene (4 mg/kg) was studied in dogs in a crossover design. Low ethanol doses (0.5 g/kg) had no effect on the bioavailability of propoxyphene. High ethanol doses (1.0 g/kg) enhanced the bioavailability of orally administered propoxyphene significantly (p less than 0.05). With this dose of ethanol, the area under the blood concentration versus time curve (AUC)0-5 h of propoxyphene was approximately 200% of the control value. The level of norpropoxyphene, a major metabolite of propoxyphene, was significantly decreased (p less than 0.05) after administration of high ethanol doses. In all blood samples, after propoxyphene administration, an unidentified metabolite of propoxyphene was found, which formation was dose dependently inhibited by ethanol.

Background: Alcoholic liver disease (ALD) is a significant global health concern, primarily resulting from chronic alcohol consumption, with oxidative stress as a key driver. The ethyl acetate extract of (CGE) exhibits antioxidant and hepatoprotective properties, but its detailed mechanism of action against ALD remains unclear. This study investigates the effects and mechanisms of CGE in alleviating alcohol-induced oxidative stress and liver injury.

Alcoholic liver disease (ALD) is a commonly known liver disease mediated by prolonged alcohol consumption. Aescin is a triterpene saponin that can manage several conditions, including brain trauma, arthritis, venous congestion, stroke, and thrombophlebitis. Even so, studies illustrating the aescin role in ALD are scarce.

Background: In approximately 80% of colorectal cancer cases, mutations in the adenomatous polyposis coli () gene disrupt the Wingless-related integration site (Wnt)/β-catenin signaling pathway, a crucial factor in carcinogenesis. This disruption may result in consequences such as aberrant spindle segregation and mitotic catastrophe. This study aimed to analyze the effectiveness of the ethanolic extract of red okra () pods (EEROP) in inducing apoptosis in colorectal cancer cells (SW480) by inhibiting the Wnt/β-catenin signaling pathway.

Background And Aim: , a nematode that frequently infects the digestive tract of chickens, is a significant concern for poultry health. In response, the use of medicinal plant-derived anthelmintics was proposed as a potential solution. This study observed the effectiveness of a single, graded dose of the ethanol extract of , L.
