Abstract:
Aim To observe the effect of“Ying-nutrient and Wei-defense unblocking collaterals prescription”on the carotid sympathetic nerve in early atherosclero-sis. Methods The rabbits were randomly divided into 6 groups:Control group, high-fat group, Complex mod-el group, GSTL-H group, GSTL-L group and ATO group. The control group was fed with common food-stuffs, High-fat group with high-fat diet to build early atherosclerosis model, and all the other groups with high-fat diet combined with carotid artery cannula to build early atherosclerosis carotid artery injury rabbit model. All groups were given corresponding medicines intragastrically once a day for 4 weeks. The GSTL-H and GSTL-L group was given Guishaotongluo ultrafine powder 0. 6 g·kg-1·d-1, 0. 3 g·kg-1·d-1, and the ATO group was given suspension of atorvastain so-lution 2. 5 mg · kg-1 · d-1 . Biochemical method was used to detect blood lipid change. HE staining was ap-plied to observe the pathological morphology of intima-media, The content of NE in the carotid arterial was detected by ELISA. The immunohistochemical staining was used to detect the protein expression of NGF, TH around the carotid arterial. The expression of NGF, TH in the carotid artery adventitia was detected by Western blot. Results Compared with normal group, the levels of TC,TG and LDL-C in high-fat group and complex model group were significantly increased( P<0. 01). The degree of the intimal hyperplasia,the con-tent of NE and sympathetic density ( NGF, TH protein expression and distribution ) of the cartoid artery in complex model group were heavier compared with those in high-fat group; the lipid levels, degree of the inti-mal hyperplasia and sympathetic density ( NGF, TH protein expression and distribution ) in the GSTL-H, GSTL-L group were milder in varying degrees compa-ring with those in the complex model group(P<0. 05, P<0. 01 ) . Conclusion “Ying-nutrient and Wei-de-fense unblocking collaterals prescription” can reduce rabbit carotid atherosclerosis, and the mechanism may be related to regulating the sympathetic nerve of arterial wall.
