Abstract Blood glucose, tissue carbohydrate, total plasma and tissue protein and plasma electrolyte concentrations were estimated in male toads, exposed to simulated high altitude of 12,000, 18,000 and 24,000 feet respectively for 48 hours of continuous exposure in a decompression chamber. Blood glucose and muscle carbohydrate were decreased significantly in animals exposed to 18,000 and 24,000 feet altitude, without having any change in the liver carbohydrate. Muscle carbohydrate was also decreased in 12,000 feet altitude exposed animals. Plasma protein content was increased significantly in 18,000 and 24,000 feet altitude exposed animals, whereas no such change was noted in tissue protein content. A slight increase of plasma sodium concentration was found in animals exposed to 24,000 feet, and a decrease of potassium concentration was also noted in 18,000 and 24,000 feet exposed animals. Magnesium concentration of the plasma was increased in 18,000 and 24,000 feet exposed animals. This animal had also shown an eosinopenia, lymphopenia and neutrophilia when exposed at 24,000 feet high altitude.
