MSCLE TISSUE CHANGES IN EXPERIMENTAL FROSTBITE

Effect of endurance exercise training on morphological changes in rat heart tissue following experimental myocardial infarction

Introduction: Cardiac remodeling after myocardial infarction, is associated with progressive ventricular dysfunction and cardiovascular death. The purpose of this study was to examine the effect of endurance exercise training on morphological changes in rat heart tissue following experimental myocardial infarction. Materials and methods: Rats used in this experiment (8-10 weeks old, 235 &p...

Changes of stress oxidative enzymes in rat mammary tissue, blood and milk after experimental mastitis induced by E. coli lipopolysaccharide

The present study investigated the effects of E. coli lipopolysaccharide (LPS) induced mastitis model in rat on the activity of antioxidant enzyme systems. To achieve this purpose, E. coli LPS were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. The...

Sickle cell trait and frostbite.

Frostbite: incidence and predisposing factors in mountaineers.

BACKGROUND Frostbite, the most common cold injury, occurs in mountaineers, a major group at risk, more often than in the general population. OBJECTIVES To describe the incidence of frostbite and the situations associated with it in mountaineering, emphasising factors that can be modified to decrease its frequency and severity. METHODS In this cross sectional, questionnaire based study, 637 ...

CHAPTER 139 Frostbite

Unlike other animals that live outside the tropics, humans are susceptible to peripheral cold injuries. The highest homeostatic priority is to maintain the body’s core temperature. This is accomplished through peripheral vasoconstriction and shunting, which prevent adequate heat distribution to the extremities. As a result, failure to achieve adequate protection from the environment results in ...
