摘    要:目的:研究AVP对VSMC脂质过氧化的影响及CGRP、SP的调节作用。方法:以培养的大鼠血管平滑肌细胞(VSMC)为模型,动态观察了精氨酸加压素(AVP)对VSMC脂质过氧化的影响,及降钙素基因相关肽(CGRP)、P物质(SP)对AVP作用的调节,旨在探讨它们在高血压病发病中的意义。结果:(1)10-7M的AVP作用后,VSMP的丙二醛(MDA)含量明显高于对照组(P<0.01);(2)10-7M的CGRP、SP分别与10-7M的AVP共同作用后,VSMP的MDA含量均减少,与AVP对照组比较,差异非常显著(P<0.01)。结论:AVP参与高血压病的发病与其致VSMC的脂质过氧化损伤有关,CGRP、SP对其有拮抗作用。

关 键 词:精氨酸加压素  血管平滑肌细胞  脂质过氧化  血管活性肽

Abstract:Objective To study the effects of AVP on VSMC lipid peroxidation and the regulation of CGRP and SP on AVP. Method:Taking the cultured vascular smooth muscle cells (VSMC) of rats as the medel, we dynanlically observed the effects of arginine - vasopressin (AVP) on VSMC lipid Peroxidation and the regulation of calcitonin gene - ralated peptide (CGRP) and substance P (SP) so as to study the pathogenic effect of these factors on hypertension. ResultS: (1) Under the effects of 10 - 7 M of AVP, the content of MDN in VSMC was significantly higher than that in control group (P < 0 .01 ). (2) Under the effect of 10 -7 M of CGRP and SP together with 10 -7 M of AVP rpspectively , the content of MDA in VSMP were all decreased. Compared with the control group, the difference was significant (P < 0.01 ). Conclusion: The involvement of AVP in the formation of hypertension is asaseiated with the damage in VSMC lipid perokidation and CGRP and SP have antaponistic effect on AVP.
Keywords:AVP  VSMC  lipid peroxidation   vasoactive peptides
