title: Effect of some drugs, experimental stress and estrus on unstable and fixed conditioned alimentary motor reflexes in cats. Meclophenoxate, chlorprothixen, caffeine, piracetam. Part VI.
abstract: A group of 10 cats, both sexes, were studied for the effect of peroral administration of the meclophenoxate (Cetrexin, Léciva, 1.5 mg kg-1) + chlorprothixen (Chlorprothixen, Spofa, 0.045 mg kg-1) + caffeine (Coffeinum natrium benzoicum, Spofa, 0.15 mg kg-1) combination upon the fixation of conditioned alimentary motor reflexes to a sound signal in the course of a 10-week experiment. The mentioned combination of drugs demonstrated a beneficial protective influence on the fixed alimentary motor reflexes against laboratory stress. The results were compared with the earlier fixation of the same reflexes in another group of 11 cats under piracetam (Nootropil, U.C.B. 20 mg kg-1, s.c.). In both groups of animals, the development of reflexes was performed in regular alterations of experiments under the effect of the drugs and control experiments. The drugs were administered 1 hour before the experiments. Both groups of animals showed significantly fewer intersignal and other incorrect motor reactions on the days they were given the drugs than the controls did. The number of fixed correct reactions and their latencies displayed only moderate insignificant differences between the pharmacological trials and the controls. The conclusions is that the actual development of conditioned alimentary motor reflexes was not found to be influenced by the action of the mentioned drugs modifying psychological functions and mental states.
