چکیده

The demonstration by Martius and Nitz-Litzow (4), and Martius (5), that vitamin K1 may play a functional role in oxidative phosphorylation in animals has led to an increased interest in the participation of vitamin Ki and related quinones in electron transport, oxidative phosphorylation, and photosynthetic phosphorylation. Since vitamin K1 is altered by the action of ultraviolet radiation (6), we have treated rat liver mitochondria with near-ultraviolet light in order to alter such intramitochondrial components. After such treatment, oxidative phosphorylation with succinate as substrate is dependent upon the addition of cytochrome c, and oxidative phosphorylation with glutamate as substrate is dependent upon the addition of cytochrome c and vitamin K1. The action of vitamin K1 appears to be specific in that a number of related compounds do not restore oxidative phosphorylation.

The effect of vitamin K1 on oxidative phosphorylation of rat liver mitochondria irradiated with ultraviolet light.

Almost 20 years have elapsed since the isolation of vitamin K1 by Doisy et al. (1) and Dam et a?. (2); yet, there is still no adequate explanation for its action in animals. It has been recsognized for some time that. vitamin K is required for the synthesis of prothrombin (3, 4) but it has never been established whether this is a specific or nonspecific effect. It has been found that vitamin K1...

Anti-oxidant effects of propofol (2, 6-diisopropylphenol) were evaluated agains carbon tetrachloridet CCl4 -induced oxidative stress in rat liver. 30 male rats were equally divided in to 6 groups (5 rats each). Group I (control), while Group II was given CCl4 (3 mL /Kg/day, IP). Animals of Groups III received only propofol (10 mg/Kg/day, IP). Group IV was given propofol+ CCl4. Group V was admin...
