The radical scavenging activity of Laminaria japonica pigments was studied by the DPPH2,2-Diphenyl~(-1-picrylhydrazylassay. The total pigments showed a strong DPPH radical scavenging activity of 65.819% with the concentration of 0.52mg.ml~(-1). The DPPH radical scavenging activity of fucoxanthin was 19.85% with the concentration of 0.27mg.ml~(-1). The antimicrobial activity of pigment in Laminaria japonica was studied by the method of round paper. The results showed that the pigment extracts have activity against Escherichia coli, Pseudomonas aeruginosa, Saricina flava and Saccharomyes cerevisia. The antibacterial activity of total pigments for Saccharomyes cerevisia was the strongest with an inhibition diameter of 18.9 mm; and the antibacterial activity of fucoxanthin for Saricina flava was also much significant with an inhibition diameter of 10.2 mm.

Result:The result manifestation of two sets of MBCs of basis two kinds of germ stubs:The average value of the MBC of golden color staphylococcus is basically low in matched control in the experiment set the MBC of golden color staphylococcus is equally worth a steps degree;But the MBC of the pneumonia streptococci in the on trial set be equally worth for and pneumonia streptococci within matched control the MBC equally is worth mostly and same alike.

结果：根据两种菌株的两组MBC的结果显示：实验组中金黄色葡萄球菌的MBC的平均值基本上低于对照组中金黄色葡萄球菌的MBC平均值一个梯度；而试验组中的肺炎链球菌的MBC平均值为与对照组中的肺炎链球菌MBC平均值大致相同。

The main pathogens of VAP were Gram negative organisms (68.63%) whose predominant pathogens were Pseudomonas aeruginosa and Acinetobacter. On the other hand, 75.40% of Gram positive organisms were Staphylococcus epidermidis.Of the pathogens 20.98% were eumycetes. Compared from June 1996 to June 2001 with from July 2001 to June 2006,there was no significant difference on the incidence rate of P.aeruginosa(31.76% vs 31.58%).During the recent 10 years,the incidence of Acinetobacter rose up from 8.23% to 15.23% and the rate of oxacillin-resistant Staphylococcus epidermidis rose up from 18.75% to 71.43%. The sensitivity of P.aeruginosa and Acinetobacter isolates descended to sodium imipenem cilastatin and ceftazidime in past 10 years.

在538例VAP中，2种及2种以上致病菌感染占56.51%；革兰阴性细菌中，铜绿假单胞菌和不动杆菌属为VAP的主要致病菌(68.63%)(385/561)；表皮葡萄球菌感染为VAP的主要革兰阳性致病菌(75.40%)(95/126)；真菌占20.98%(183/872)；铜绿假单胞菌在两个时间段所占比例无明显变化，不动杆菌属的检出率呈上升趋势(8.23%～15.23%)；铜绿假单胞菌和不动杆菌属对亚胺培南、头孢他啶的敏感性明显下降，耐苯唑西林表皮葡萄球菌的检出率显著升高(18.75%～71.43%)。
