previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 the present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. dose/response relationships for adrenaline and noradrenaline produce...

the present study was conducted on buffaloes that were non-cycling (heifers, n=32; lactating, n=13) or cycling (heifers, n=11; lactating, n=27) and in the buffaloes that conceived (heifers; n=11; lactating, n=23)or failed to conceive (heifers, n=32; lactating, n=17) subsequent to artificial insemination. plasma samples were analyzed for thyroid stimulating hormone, thyroid hormones, glucose, to...
