Assessment of T-2 toxin effect and its metabolite HT-2 toxin combined with insulin-like growth factor I, leptin and ghrelin on progesterone secretion by rabbit ovarian fragments.

Assessment of A-trichothecene mycotoxins (T-2 and HT-2 toxins) effect combined with growth factor IGF-I, and the metabolic hormones leptin and ghrelin on progesterone secretion by rabbit ovarian fragments was studied. Rabbit ovarian fragments were incubated without (control group) or with T-2/HT-2 toxin, or their combinations with insulin-like growth factor I (IGF-I), leptin or ghrelin at various concentrations for 24 h. Secretion of progesterone was determined by ELISA.
