Oxidative metabolism is fine-tuned machinery that combines two tightly coupled fluxes of glucose and glutamine-derived carbons. Hypoxia interrupts the coordination between the metabolism of these two nutrients and leads to a decrease of the system efficacy and may eventually cause cell death. The subterranean blind mole rat, , is an underexplored, underground, hypoxia-tolerant mammalian group which spends its life under sharply fluctuating oxygen levels.

However, some vertebrate species, such as aquatic turtles, seals, naked mole rat, and blind mole rat, , have adjusted their homeostasis to continuous function under severe hypoxic environment. The exploration of hypoxia-tolerant species metabolic strategies provides a better understanding of the adaptation to hypoxia.

Panthenol and L-carnitine administered separately normalized the activity of aldehyde dehydrogenases, while a combination of the drugs did not produce any significant effect.

Administration of Perftoran in the period of ethanol withdrawal eliminated the signs of oxidative stress and prevented elevation of enzyme activities in the blood, which reflects improvement of structural and functional characteristics of liver cell membranes.

Male Wistar rats were treated with introperitoneal injections of 1% morphine hydrochloride twice a day. The daily dose of morphine was gradually increased trom 10 mg/kg (1-2 days) to 20 mg/kg (3-4 days), and up to 40 mg/kg starting at the fifth day.
View Article and Find Full Text PDFAlcohol administration can result in liver damage. Reactive oxygen species (ROS), nitric oxide (NO) and their interaction are crucial factors in this process. The aim of work was to investigate, free radical state and mechanisms of adaptation of the antioxidant system (AOS) to stress, caused by interrupted alcohol intake.
