[Effect of thymalin on the function of the blood kallikrein-kinin system in thymectomized rats].

The effects of thymus ablation and injection of thymalin on the blood plasma kallikrein-kinin system were studied. Thymus ablation was followed by activation of kinin formation, evidenced by an elevation of the total kallikrein activity and drop of the kininogen level. Injection of thymalin into thymectomized animals makes the characteristics under study return to normal.
