【摘要】：檢測促黃體生成素受體(LHR)在雌性山羊頸動脈體(CB)中存在及其分布特點(diǎn),為促黃體生成素(LH)是否對CB起調(diào)節(jié)作用提供形態(tài)學(xué)基礎(chǔ)。取雌性山羊的CB進(jìn)行LHR免疫組織化學(xué)(SP)法染色觀察與分析。結(jié)果表明:LHR免疫陽性物質(zhì)在頸動脈體中分布廣泛;鏡下可見,在CB的小球結(jié)構(gòu)內(nèi),Ⅰ型、Ⅱ型細(xì)胞的細(xì)胞膜LHR免疫陽性物質(zhì)呈棕黃色,為強(qiáng)陽性,在其細(xì)胞質(zhì)和細(xì)胞核中LHR免疫陽性物質(zhì)呈黃色,為中等陽性;CB的間質(zhì)組織中,血管內(nèi)皮細(xì)胞LHR免疫陽性物質(zhì)呈棕黃色,為強(qiáng)陽性;此外間質(zhì)還可見許多點(diǎn)狀或線狀的非細(xì)胞陽性結(jié)構(gòu),呈淡黃色,為弱陽性。對實(shí)質(zhì)細(xì)胞群和間質(zhì)組織平均光密度的分析結(jié)果表明,CB的實(shí)質(zhì)細(xì)胞是LH作用的主要靶細(xì)胞之一,提示LH可能通過CB實(shí)質(zhì)細(xì)胞上的LHR來介導(dǎo)生物學(xué)效應(yīng),影響CB的實(shí)質(zhì)細(xì)胞對血液內(nèi)化學(xué)刺激的感知,間接的影響動物機(jī)體心血管的功能。
[Abstract]:The presence and distribution of luteinizing hormone receptor LHRin (LHRR) in female goat carotid artery (CBB) were detected, which provided a morphological basis for the regulation of LH on CB.CB of female goats was observed and analyzed by LHR immunohistochemical staining.The results showed that the immunoreactive substances of LHR were widely distributed in the carotid body, and the LHR immunopositive substances of type 鈪，
