Abstract
  1. The possible role of thromboxane in the uterotrophic response to oestrogen, in the spontaneously hypertensive rat was investigated by use of the thromboxane receptor antagonists EP092, AH23848 and BM 13.505. 2. The parameters studied were uterine blood flow (measured by the microsphere technique), uterine wet and dry weights and the concentrations of cytosolic and nuclear oestrogen receptors. 3. The antagonists attenuated oestradiol-induced uterine blood flow and significantly reduced both wet and dry uterine weight. These changes were accompanied by decreases in nuclear oestrogen receptor levels. 4. The results suggest a supportive role for thromboxane in oestradiol-induced uterine growth.
摘要
  1. 通过使用血栓素受体拮抗剂EP092、AH23848和BM 13.505,研究了血栓素在自发性高血压大鼠子宫对雌激素营养反应中的可能作用。2. 所研究的参数包括子宫血流量(通过微球技术测量)、子宫湿重和干重以及胞质和核雌激素受体的浓度。3. 拮抗剂减弱了雌二醇诱导的子宫血流量,并显著降低了子宫湿重和干重。这些变化伴随着核雌激素受体水平的降低。4. 结果表明血栓素在雌二醇诱导的子宫生长中起支持作用。
