Then test of film cell growth by high sugar, LPS, high sugar plus LPS was done with the result showing that FANG KIDNEY capsule can restrain the growth of film cell and composition of external base, it can be concluded that it has obvious effect in preventing the hardening of kidney small cell.

为进一步探讨糖肾胶囊的作用机制，还采用国内外经典细胞培养方法，成功地培养出肾小球系膜细胞，在此基础上进行高糖、LPS、及高糖加LPS诱导细胞膜增生，结果发现糖肾胶囊能抑制系膜细胞增生及细胞外基质胶原合成，证明其对防止肾小球硬化有明显作用。

The effect of initial pH, temperature and N263 concentratio n on extraction of fucoidan was investigated. It has shown that temperature and initial pH of the solutions have no great influences on the extraction of fucoid an, and when N263 concentration is low, an increase in the concentration incre ases the extraction of fucoidan.
