    Notes: Abstract Blocking central muscarinic (M-) cholinergic systems with benactyzine facilitates the manifestation of the contraceptive effect of estrogen norsteroids in early pregnancy in rats. This effect is connected with lowering of the gonadotropin level and a change in the ratio between follicle-stimulating and luteinizing hormones, interfering with implantation of the fertilized ovum in the endometrium. The rate of transport of the ovum along the fallopian tube and development of the decidual reaction are also changed. The change in rate of movement of the ovum is not accompanied by any disturbance of fertilization. The substances tested showed no cytotoxic action. The use of mestranol and ethinylestradiol in conjunction with norethinodrel and benactyzine may prove promising as a method of short-term contraception in the postcoital period.

    Notes: Abstract The body weight and morphometric parameters of the state of the pancreatic insular apparatus (the relative percentage of islet tissue, of A- and B- cells, the number of islets) in fetuses and the adult offspring of healthy female rats and male rats with alloxan diabetes were studied. No change in these parameters was found, indicating that under these conditions the genetic systems of the males are undamaged and that these lesions are not transmitted to the progeny. On the basis of these findings and of the importance of diabetes in the female in the development of insular deficiency in the progeny demonstrated previously, the role of the environment in which the fetus develops in the formation of the diabetes is emphasized.
