问题:本研究测定血小板活化因子(PAF)与卵巢和输卵管组织的结合,以确定PAF-组织相互作用的位置。
方法:采用冷冻切片和放射自显影法,对发情周期和受孕后第1、4和7天(pc)采集的小鼠卵巢和输卵管进行[ H]PAF结合分析
。动情期和卵巢后壁的PAF结合率无显著性差异(P>0.05),而动情前期和动情期的PAF结合率有显著性差异(P<0.001)。卵巢基质PAF结合率在动情期显著高于动情后期(P<0.001),动情前期无PAF结合。PAF与动情期卵泡的结合率显著高于动情前期和动情后期(P<0.001)。动情期输卵管基质、内上皮和管腔PAF结合率均显著升高(P<0.001)。在交配后第1天和第7天,所有卵巢组织都有最大的PAF结合,而交配后第4天除黄体结合率显著降低外,其余卵巢组织均未结合PAF(P<0.001)。PAF的输卵管结合在pc第1天最大
。卵巢和输卵管PAF受体的表达与胚胎PAF合成高峰相对应,为PAF-PAF受体介导的早孕信号传导系统奠定了基础。
PROBLEM: This study determined platelet activating factor (PAF) binding to ovaries and oviduct tissues to identify the location of PAF–tissue interaction.
 METHOD: Mouse ovaries and oviducts taken during the estrous cycle and days 1, 4 and 7 post‐conception (pc) were analyzed by [ H]PAF binding using frozen sections and autoradiography.
 RESULTS: For the outer epithelium of estrous and metestrous ovaries there was no significant difference in PAF binding (P>0.05); however, both stages were significantly different from proestrous (P<0.001). Ovarian stroma PAF binding was significantly higher (P<0.001) at estrous than metestrous, with no PAF binding at proestrous. Binding of PAF to estrous ovarian follicles was significantly greater (P<0.001) than at proestrous and metestrous. Estrous oviduct binding of PAF was significantly increased for stroma, inner epithelium and lumen (P<0.001 in all cases). At days 1 and 7 pc, all ovarian tissues had the greatest PAF binding with day 4 pc failing to bind PAF except for a significant decrease in corpora luteal binding (P<0.001). Oviduct binding of PAF was greatest at day 1 pc.
 CONCLUSION: Ovarian and oviduct PAF receptor expression corresponds to peak embryo PAF synthesis and establishes the basis for PAF–PAF receptor mediated early pregnancy signaling system.
