    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 In experiments on dogs a single injection of insulin in a dose of 1 unit/kg body weight caused an increase in the maximal reabsorption of glucose and secretion of diodone and reduced the excretion of sodium without any change in glomerular filtration. These effects depend on the direct action of insulin, for when it was injected directly into one of the renal arteries its action was manifested only in the kidney on the side of infusion. Prednisolone had no significant effect on glucose and diodone transport when given as a single injection (3–4 mg/kg) or over a period of 10 days (1.5–2 mg/kg daily).
