Abstract: | A study was made of the action of a specific muscarinic antagonist 3H-quinuclidinyl benzylate on the immune rosette formation in BALB/c mice. It was shown that treatment of mouse spleen lymphocytes by 3H-QNB at a concentration of 10(-9) M-10(-14) M brought about rosette formation inhibition. The process was dose-dependent. Atropine reversed the action of 3H-QNB. |
