This article describes the features of quantitative distribution of glucocorticoid steroid hormones — hydrocortisone and corticosterone – at different stages of the life cycle of the Mediterranean mussel (Mytilus galloprovincialis) and the European flat oyster (Ostrea eduliss). The author identifies a common pattern of hormone dynamics ...

... some cases (infectious and tumourous disease), aim to strengthen and, in other cases (autoimmune diseases and allergy), to suppress (weaken) the immune processes. The factors affecting the formation of immunological memory are numerous and varied. The steroid hormones are considered the most abundant group of biologically active agents. The influence of these agents on proliferation, differentiation and apoptosis of immune system cells is being intensively studied. This review analyses the data on the role ...

This article describes the effect of three hormonal specimens — two analogues of sex steroid hormones (progesterone and testosterone) and a glycocorticoid hormone prednisolone (dehydrogenated analogue of hydrocortisone) —on the process of regeneration of freshwater planarian Dugesia lugubris Schmidt, 1861. The hormonal specimens differing on ...

The article describes the quantitative content dynamics of the hydrocortisone steroid hormone in different organs and tissues in the course of the common octopus ontogenesis. The author detects general patterns of its quantitative distribution in the octopus organism and formulates a hypothesis on the functional significance of hydrocortisone ...
