Effect of thyroliberin on the course of experimental candidosis in mice

Thyroliberin (TRH) is one of the hormones, which affect immunologic processes. This hormone was studied in experimental subacute candidosis in mice. BALB/c males were given intraperitoneally single dose of Candida albicans cells (1 x 10(7) to 1 x 10(9) cfu of strain no. 244-33 ATCC). The animals from the experimental groups were injected subcutaneously, after 24 h from inoculation, dose of 10 microg TRH in 0.2 ml 0.9% NaCl, seven times at 24 h intervals. The control animals were given respectively 0.2 ml of physiologic NaCl solution. We have found that the examined hormone significantly decreases mortality in these animals (LD50 C. albicans for mice treated with TRH was three times higher than that in the control groups), prolongs mean survival time for mice and decreases the intensity of fungal invasion of the animal organs.
