Effect of low body temperature on gastric secretory activity in the guinea pig under urethane general anaesthesia.
Effect of low body temperature on gastric secretory activity in the guinea pig under urethane general anaesthesia. Acta Physiol. Pol., 1978, 29 (1): 61-66. The effect of low body temperature on spontaneous and histamine (H) stimulated or Nalpha Nalpha-dimethylhistamine (NDMH)-stimulated gastric secretion was investigated in the guinea pig under general anaesthesia with urethane. In normothermia NDMH had a stronger stimulatory action on acid secretion In hypothermia (30 degrees C and 25 degrees C) only NDMH showed some stimulating effect. The obtained results point to the necessity of strict controlling of body temperature in the experiments performed on animals under general anaesthesia and suggest that the lack of effect at low temperature may be connected with an inhibition of the processes of H side-chain methylation when the rate of metabolic processes in the organism has fallen.
