PRELIMINARY INVESTIGATION ON THE DETERMINATION OF ?-ADRENOCEPTORS IN RAT UTERUS DURING OESTROUS CYCLE / 重庆医科大学学报

ABSTRACT

The number and affinity of ?-adrenoceptors on rat uterine smooth muscle membranes were determined by radioligand binding technique. The number of ?-adrenoceptors (shown by maximum binding capacity RT) of uterus in proestrus and estrus stage (126.84?54.69 fmol/mg preicin) was significantly higher than those in diestrus and metestrus stage (77.98 + 30.66 fmol/mg protein) (p
