[Effect of the short term exposure to heat on the adreno- and cholinosensitivity of the small intestine in the rat].

A 10-day study of the dynamics of adreno- and cholinosensitivity of isolated fragments of the small intestine of Wistar rats exposed to temperature of 45 degrees C for 30 and 60 min, revealed an increase in adreno- and cholinosensitivity in hyperthermia. A significant correlation exists between the body temperature and adrenoreactivity. Normalizing of body temperature is followed by reciprocal changes in adreno- and cholinosensitivity.
