二参泽术汤对腹膜淋巴孔的影响及腹水转归机理的研究

Effect of Ershen Zeshu Mixture on the peritoneal lymphatic stomata and the ascites drainage

目的 :研究二参泽术汤对腹膜淋巴孔的调控作用和治疗腹水的意义 ,并应用NO供体 (硝普钠 )和一氧化氮合酶 (NOS)抑制剂 (NG-单甲基 -L -精氨酸 ) ,观察NO的淋巴孔舒张作用和对腹水转归影响 ,探讨二参泽术汤对腹膜淋巴孔的调控机制。方法 :应用CCl4 法建立小鼠肝纤维化模型 ;用扫描电镜观察 ,并使用计算机与扫描电镜联机的图像处理系统测定腹膜淋巴孔的变化 ;用全自动生化分析仪测定尿离子浓度。结果 :①二参泽术汤可明显促进腹膜淋巴孔开放面积增大 ,周长和分布密度增加 (P <0 0 1 ) ,尿中Na+ 、K+ 、Cl- 排出增多 (P <0 0 5或P <0 0 1 ) ;②二参泽术汤对腹膜淋巴孔的调控和对腹水转归的作用可以被NO供体和NOS抑制剂增强或抑制。结论 :①二参泽术汤能调控腹膜淋巴孔 ,促进腹膜腔内液体转归 ,使尿中Na+ 、K+ 、Cl- 排出增加 ,减轻水钠潴留 ,具有良好的消腹水作用 ;②二参泽术汤调控腹膜淋巴孔 ,促腹水转归机制 。

AIM: To further study the effect of Ershen Zeshu Mixture, a Chinese medicine, on the peritoneal lymphatic stomata and the ascites drainage in experimental mice model of CCl 4-induced fibrosis.By the application of NO supplier (sodium nitroprusside,SNP) and NO suppressor (N G-mononethyl-L-arginine,L-NMMA),the effect of NO on the peritoneal lymphatic stomata and the ascites drainage was studied to clarify the relationship between Ershen Zeshu Mixture and NO in the regulation of the peritoneal lymphatic stomata.METHODS: The mouse model of fibrosis was established with the application of intragastric installations of carbon tetrachloride one time every three days;Scanning electron microscope and computer image processing were used to detect the girth,area and distribution density of the peritoneal lymphatic stomata;the concentration of urinary ions was measured in the experiment.RESULTS: ①Compared to NS group and model group,Ershen Zeshu Mixture could significantly increase the girth and the area of the peritoneal lymphatic stomata,promote its distribution density ( P <0 01) and enhance the drainage of urinary ions such as sodium,potassium and chlorine( P<0 05 or P <0 01).②The effect of Ershen Zeshu Mixture on the peritoneal lymphatic stomata was altered by adding NO supplier or NOS suppressor to the peritoneal cavity,that is ,NO supplier can enhance the regulation effect of Ershen Zeshu Mixture on the peritoneal lymphatic stomata,but NO suppressor can antagonize the Ershen Zeshu Mixture's effect.CONCLUSIONS: ①These observations indicated that Ershen Zeshu Mixture might regulate the peritoneal lymphatic stomata to drainage materials in the peritoneal cavity.②The effect of Ershen Zeshu Mixture on lymphatic stomata and ascites drainage maybe have relationship with endogenous NO.
