The standardized extract of Ginkgo biloba (EGb 761) was found not only to improve memory and aging associated cognitive deficits but also to exert beneficial effects on mood. An antistress action of the extract has been suggested but not directly proven. The present study was aimed to evaluate the effects of EGb 761 on salivary cortisol and blood pressure responses during stress in healthy young volunteers...
Ageing is characterized by a gradual decline in organ functional reserves which reduces the ability to maintain homeostasis under conditions of stress. Introduction of cell culture and molecular biology techniques has provided new experimental tools for the analysis of ageing at the molecular level. During ageing progressive degeneration of cells and loss of regenerative capacity are enhanced and...
The first part of this review documents the mechanisms of plant resistance to water shortages during growth. It has been indicated, that appropriate supply of crop plants with potassium improves their water management and consequently results in higher resistance to stresses, including droughts. The anti-stress potassium action is a consequence of higher K+ ions concentration in the soil solution...
The experimental model of acute gastritis such as water immersion restraint (WRS) stress-induced gastric injury is useful tool in examination of pathomechanism of acute gastritis. Nitric oxide (NO) plays an important role in the maintenance of gastric barrier, however, the interaction between reactive oxygen species (ROS) and NO on gastric mucosal integrity has been little studied. The purpose of...
