The work was aimed at the investigation of adaptation influence to short stress and preliminary N-acethyl-L-cystein injection on the poststressory changes of lipid peroxidation activity and redox –system of glutathione. The cellular redox state has been estimated according to reduced (GSH) and oxidized (GSSG) glutathione ratio.The concentration of nitrates and nitrites, activity of lipid peroxidation (LPO) and general antioxidant activity (AOA) of bloods plasma have been defined in this work. The LPO activation (13%), AOA inhibition of blood plasma (19%) and oxidized glutathione accumulation and the reduction of GSH/GSSG ratio (46%) has been observed in the group of stressed animals. Adaptation to the short stressor influences has completely prevented the poststressory activation of lipid peroxidation, the reduction of antioxidant activity, accumulation of nitric monoxide degradation products and restored the GSH/GSSG ratio. Preliminary N-acethyl-L-cystein injection possessed by the similar properties as adaptation to the short stressory influences, i.e. prevented the poststressory changes in cellular redox-state, reduction of antioxidant activity, activation of lipid peroxidation and superfluous nitric monoxide accumulation. : , 210023, . , . 37-07-54 - , . , 27, , . , . , .
