Under the optimum conditions, the liner range is 0 to 200 mg/L for BSA and 0 to 125 mg/L for HSA, the molar absorptivity is 1.61×10^5 Lmol^(-1)cm^(-1) for bovine serum albumin and 1.75×10^5 Lmol^(-1)cm^(-1) for human serum albumin. Based on this, a new method is proposed to determine protein. After the method is applied in the determination of the total proteins in real human serum samples, the results are in good agreement with the Kjeldahl method.

Results The latent phase of the primary culture cells was 5-9 days, followed by 11-16 days of logarithmical proliferation; the plateau began at day 18-20. The subcultures showed 12-24 hours of latent phase, followed by 7-10 days of logarithmical proliferation, then entered the plateau (11-13 days). The hMSC expressed positive CD44 unanimously, but don′t expressed CD45. Low concentration of bFGF (10 μg·L-1) could stimulate the proliferation of hMSC significantly (P.05); while 25-100 μg·L-1 of bFGF could inhibit the ALP activity.

乳酸为肾脏糖质新生的主要来源，其含有一不对称碳，故具有D-、L-乳酸两种镜相异构物，而D-、L-乳酸两者之生成相当不同，L-乳酸是糖解作用之终产物，D-乳酸为体内一醣化终产物(advanced glycation end-products)─甲基乙二醛进行去毒化反应所生成，目前缺乏对乳酸镜像异构物与肾脏糖质新生间相关的探讨。
