A review.The association of a marked reduction α1-antitrypsin (α1-AT) and the developed emphysema was identified in 1963.Since then the structure, functions and underlying mechanism of α1-AT had been investigated in detail.With the development of α1-AT-related drugs, the clin. application of α1-AT was high lightened, which was reviewed here.

Determination of bacterial endotoxin in human coagulation factor VIII by kinetic turbidimetric limulus test
A method for determination of bacterial endotoxin in human coagulation factor VIII by kinetic turbidimetric limulus test was established.Based on interference experiment, the endotoxin was added in the samples, whose recovery should be within the range 50%-200%.The interference from limulus test was eliminated by diluting the Human coagulation factor VIII (1→100 solution).Turbidimetric-kinetic method was feasible and had the same result with the rabbit-pyretogen test.

Determination of residual TNBP on freezing human fibrin sealant kit by GC
作者: Sheng, Fengxian
The residual quantity of tri-Bu phosphate (TNBP) in freezing human fibrin sealant kit was determined by GC.HP-20M column was used with tri-Pr phosphate (TPP) as the internal standardThe injector, detector, and column temperature were 190, 210, and 140°, resp.The carrier gas was N2.The standard curve was linear in the range of 2-16 μg mL-1 (r = 0.999 5).The average recovery was 100.2% (RSD 2.78%).
