Ontogenetic Dynamics of Hydrocortisone Quantitative Content of the Common Octopus Octopus vulgaris, Lamark (Cephalopoda: Octopodidae)
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 ...
Daphnia magna Straus (1826) (Cladocera, Crustacea) as a test object for assessing endocrine disorders in aquatic organisms
This article examines the effect of prednisolone – an analogue of the ver-tebrate hormone hydrocortisone – on the activity of somatic growth, blood sys-tem function, fecundity, and reproductive rate in Daphnia Straus (1826) (Cladocera, Crustacea) in three consecutive generations. This hormone had a proven effect on the studied morpho-functional ...
Steroid hormone in marine bivalve molluscs of the annual cycle
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 consisting in ...
The effect of exogenous hormonal compounds on the process of regeneration in flatworms
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 chemical nature and physiological activity have differently directed effect on the processes of regeneration....
