The present report examines the in vitro genotoxicity (micronucleus assay) of herbicides and adjuvants and reports on an in vivo human study on potential endocrine effects of pesticides, including herbicides. Adjuvants are used in conjunction with 2,

Improved methods are needed to evaluate the effects of occupational and environmental hazards on the reproductive health of human female populations. This communication describes highly specific, sensitive, and reliable time-resolved fluorescence imm

The effect of estradiol-17a(E2) in regulation of basal and luteinizing hormone releasing hormone (LHRH) mediated release of LH was studied. Bovine anterior pituitaries were dispersed and "o5 X iocells in 1 ml medium were dispensed to each well of mul

In ovariectomized heifers, oestradiol decreases concentrations of LH in serum for approximately 12 h after which LH is released in a surge comparable in size and duration to the preovulatory surge. Using this model, we measured LH release induced by

To study the mechanism by which estradiol induces a preovulatory surge of follicle stimulating hormone (FSH), we concluded experiments designed to determine: (1) the time course of change in luteinizing hormone releasing hormone (LHRH)-induced FSH re

Destruction of ovarian follicles during diestrus prolongs the lifespan of corpora lutea in cows, but the site(s) of action is unclear. Thus, ovarian follicles were destroyed in 10 heifers (X-1RRAD) on Day 9postestrus, while 10 additional heifers (SHA

The goal of this study was to pharmacologically block central nervous system (CNS) input to gonadotropes in mature ovariectomized gilts to determine the direct actions of estradiol (E2) on pituitary LH release when given at a dose sufficient to elici

In ovariectomized pigs, estradiol treatment induces a preovulatory-like luteinizing hormone (LH) surge, but only after serum LH concentrations are suppressed for 48 h. This inhibition of LH release is attributable in large part to inhibition of gonad

Effects of duration, intensity and wavelength of light on growth hormone (GH), glucocorticoids, thyrotropin (TSH) and thyroxine (T4) concentrations in serum were determined in prepubertal bulls maintained at 18 to 22 C and 60 tp 70% relative humidity
