On model of scald trauma the correlation of electrophoretic mobility of rat blood erythrocytes with intensity of lipid oxidation of erythrocyte membranes and with activity of catalase were studied. It is shown that in dynamics of scald disease development the erythrocyte mobility decreases, the velocity of oxidizing ability of their lipids increases and the protective action of blood antioxidation system is blocked. It is found that there is a close dependence between the level of oxidative processes and electrogenic properties of erythrocytes at the height of manifestation of scald toxaemia. A conclusion was made that the oppressing influence of increasing lipid oxidizing ability a on electrokinetic potential of erythrocytes is of a threshold nature and is realized through change in the membranes' state of these cells.

Recently, exposure to sounds with ultrasound (US) components has been shown to modulate brain activity. However, the effects of US on emotional states remain poorly understood. We previously demonstrated that the olfactory bulbectomized (OBX) rat depression model is suitable for examining the effects of audible sounds on emotionality.

This study is designed to assess the effect of root extract of P. ginseng on kidney tissue injury attributed to cisplatin and its molecular mechanism involved in this process in the AKI rat model. Twenty-four male Wistar rats were randomly allocated into 4 experimental groups including: the control group, the cisplatin group, the extract 100 mg/kg group, and the extract 200 mg/kg group.

Background: Hydrogen sulfide (HS) is a widely studied gasotransmitter, and its protective effect against ischemia-reperfusion damage has been explored in several studies. Therefore, a requirement exists for a comprehensive study about HS effects on ischemia-reperfusion damage in flap surgery. The aim of this study is to examine the effect of hydrogen sulfide by creating ischemia-reperfusion injury in the vascular-stemmed island flap prepared from the rat groin area.

Introduction: Cold static storage (CSS) and normothermic ex-situ preservation are the most widely used donor heart preservation techniques worldwide. The current study compares both CSS and normothermic ex-situ preservation methods in terms of graft performance, morphologic changes, and acute immune response in an experimental model.
Method And Materials: Twenty rats underwent heterotopic abdominal heart transplantation after 2 h of CSS (group 1; n = 10) or normothermic ex-situ perfusion (group 2; n = 10).
Gentisic acid protects Sprague-Dawley rats from myocardial infarction through reversing electrocardiographical, biochemical and histopathological abnormalities.

Gentisic acid (GA), a cytochrome P450 metabolite of the antiplatelet drug aspirin, exhibits smooth muscle relaxant, antiatherogenic, and antioxidant activities. It also has a protective role in hypertrophic heart failure, suggesting its role in the management of myocardial infarction (MI). This study aimed to explore the protective activity of GA in isoproterenol (ISO)-induced MI in Sprague-Dawley (SD) rats in-vivo, followed by mechanistic investigation ex-vivo.
