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. The rate of proliferation generally depends on...
The endocrine function organization in flatworms
This article focuses on the endocrine function in flatworms. It is implemented with the help of two groups of hormones. Several centres of neurosecretory cell localisation were discovered in the nervous system of flatworms. The hormonal signal is transmitted with the help of adenylate cyclase system,...
