苯二氮卓受体在人胎脑、肝和胎盘中的存在已被研究。在妊娠12-15周时,发生与胎儿脑的特异性结合。[3 H]-氟硝卓特异性结合的解离常数为1.5-2 nM,最大结合位点数为2.3-3.8 fmol/mg总脑组织。在胎肝和胎盘中存在一定的特异性结合,但非特异性结合更为广泛。
The existence of benzodiazepine receptors in the human fetal brain, liver and placenta has been studied. At 12-15 weeks of gestation specific binding to fetal brain occurs. The dissociation constant of [3H]-flunitrazepam-specific binding was 1.5-2 nM and the maximum number of binding sites was 2.3-3.8 fmol/mg of total brain tissue. In the fetal liver and placenta some specific binding exists, yet the nonspecific binding is more extensive.
