TL;DR: It is demonstrated that PGF2&agr;, derived from COX-2, is the most likely EDCF underlying endothelium-dependent, thromboxane–prostanoid receptor–mediated contractions to ACh in hamster aortae with an increased importance during aging and, possibly, a similar relevance in humans.

TL;DR: Acid secretion by the rat cauda epididymidis was studied by microperfusion of the epididyal duct and by measuring the pH of the perfusate at a constant pCO2 using a micro pH sensitive electrode.

TL;DR: An in vitro inhibin bioassay method based on suppression of the FSH content in cultured rat anterior pituitary cells was applied to charcoal-treated testicular extracts of normal and bilaterally cryptorchid rats, established from the statistical evidence of parallelism between dose-response curves of the rat testicular extract and an ovine testicular lymph reference preparation.

TL;DR: These findings demonstrate the functional importance of oxidative stress, and that COX-2-derived PGF(2α) plays an important role in mediating endothelial dysfunction in RH.

TL;DR: Investigation of oestrogen and progesterone receptor distribution in levonorgestrel-treated endometrial biopsies found significantly greater mean immunostaining scores of stromal PR were observed in Norplant compared with control endometrium at all stages across the cycle, and it is undetermined whether increased PR immunoreactivity corresponds to an increase in number of functional PR.
