Experimental And Clinical Research Of Ai-Kang Granule On Inhibiting Angiogenesis And Anti-neoplastic Matastasis | Posted on:2006-06-30 | Degree:Doctor | Type:Dissertation | Country:China | Candidate:Z X Wang | Full Text:PDF | GTID:1104360155451297 | Subject:Chinese medical science | Abstract/Summary: | PDF Full Text Request | The research indicates that retailed circulation of blood owing to Qi deficiency, residual poison which has not been cleared completely and meridian blocked by windy sputum are the pathogenic features of tumor metastasis and angiogenesis, invigorating Qi to promoting blood circulation, eliminating poison to dissipate lumps and calming wind to clear meridian are therapeutic principle of inhibiting angiogenesis and anti-metastasis. Ai-Kang granule that is compound pure traditional Chinese medicine is made up according to dispensing principle and by using advanced pharmaceutic technology. Basic research including culturing cell in vitro and animal experiment and clinical trial showed that Ai-Kang granule had the effect of inhibiting angiogenesis anti-metastasis. The mechanism of action was researched from many layers and angels.In vitro the experiment utilized the method of serum pharmacology to observe the influence of different concentration of serum including AK on angiogenesis of chick-embryo allantois membrane(CAM), the growth of PG cell cultured heterochronously the originated from high-metastasis.giant cell carcinoma of lung and relative indexes of tumor angiogenesis. Results:the serum including AK had the evident inhibiting effect on angiogenesis of CAM and the growth of PG cell cultured in vitro. It could obviously inhibit PG cell vascular endothelium growth factor(VEGF), basicity fibroblast growth factor(BFGF), matrix metal protease-9(MMP-9) and the expression of mutation gene P53,promote the expression of gene NM23,block the carcinomic cells in period G0-G1 and induce apoptosis of carcinoma. It was proved by serum pharmacology that above effect of AK could be realized by oral-medicine in vivo, and be enhanced with the increase of drug-concentration in serum and the elongation of effect time. AK had synergism with chemotherapy.In vivo animal experiment using the models of Lewis lung cancer and H22 hepatocarcinoma of hematal and lymphatic metastasis observed the effect of anti-tumor and anti-metastasis and the influence on the microvessel density(MVD) in tumor tissue and VEGF. Results:AK granule had evident inhibition on the growth of animal metastatic tumor and experimental metastasis by lymph and hema. It could obviously inhibit the growth of lung metastasis tumor, decrease the MVD in the tumor tissue and its stroma and inhibit the... | Keywords/Search Tags: | angiogenesis, Neoplastic metastasis/therapy of TCM and modern medicine, Ai-Kang granule/pharmacology, PG cell, Lewis lung cancer, H22 hepatocarcinoma, angiogenesis factor, geneNM23 geneP53, apoptosis | PDF Full Text Request | Related items |
