Preliminary experimental experiences with xenotransplantations.

In our xenotransplantation experiments has been a major aim to induce specific tolerance. The results from the meeting of the donor's and the recipient's immunocompetent systems already in the period of embryonic development and/or the influence of methylprednisolone are described.

Ethanol and physostigmine effects on open field behavior in Wistar rats.

The paper is aimed at the evaluation the effect of relatively low doses of ethanol and physostigmine salicylate on behavior of the male Wistar rat in an open field test. Both drugs were administered as a solution intragastrically 1 hour before the test started in dose ranges of 0.6-1.

Effect of some drugs, experimental stress and estrus on unstable and fixed conditioned alimentary motor reflexes in cats. Meclophenoxate, chlorprothixen, caffeine, piracetam. Part VI.

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.

Effects of ethanol and physostigmine on reproduction of conditioned alimentary motor reflexes in cats--interaction with stress.

A group of 10 chronic cats with firmly established conditioned food motor reflexes were studied for the effect of various doses of physostigmine salicylate and its combination with 0.6 g/kg of ethanol. The trials were taking place one hour after peroral administration of the substances to non-stimulated and stimulated animals with synchronized intermittent light and sound.
