[Treatment of surgical stress response by neuroleptics, leu-enkephalin, glycyl-proline dipeptide, and electroanesthesia in experimental animals].

We have studied the effects of chlorpromazine, acepromazine, droperidol, and transcranial electroanesthesia upon evacuation function of the stomach in piglets and the effects of leu-enkephalin and glycyl-proline upon secretory activity of the stomach in dogs and rats during surgical stress to optimize anesthetic dosage. All pharmaceutical and nonpharmaceutical methods of anesthesia used in the experiments were implemented by actiovating stress-limiting systems in post-operational period. Leu-enkephalin, apart from stimulating the stress-limiting factors of neurohumoral systems of the organism, shifted the vector ratio of aggressive and protective factors of gastric mucosa toward strengthening of the latter. The opposite trends of changes in the secretory activity of the stomach of rats in response to surgical stress can be leveled using glycyl-proline as a component of anesthesia.
