A direct relationship between the weights of the brain and hemisphere and parameters characterizing the development of the cortex and its neurons in intact newborn rats was revealed. Parameters of brain development in newborn rats correlate with 3beta-hydroxysteroid dehydrogenase activity in the adrenal zona glomerulosa.

This paper is concerned with endosalpingeal specialisations that underlie stabilisation of unique secretions forming microenvironments within the Fallopian tube lumen, not least as they influence the final stages of sperm transport and maturation. In particular, a specific microenvironment at the ampullary-isthmic junction in the presence of the newly-shed oocyte(s), associated granulosa cells and their secretory products is thought to characterise the site of fertilisation. Attention is also drawn to the viscous glycoprotein in the caudal isthmus before ovulation: it isolates spermatozoa stored with suppressed motility from the metabolic stimulation caused by uterine or ampullary fluid.

Three phases have been detected in the fascicular zone of the white rat adrenal cortex. During the first phase (normoemia) blood stream is rather moderate, lipids accumulate in adrenocorticocytes. This results in increase of their volume and in decrease of nuclear-cytoplasmic relations.
