[Method] Periplaneta americana L. skimmed cream was decolored with activated carbon and macroporous resin, and freeze-dried to collect solid decolorization products. By investigating the yield, decolorization rate, protein retention rate and decolorization operation process, the advantages and disadvantages of the two decolorization technologies were compared. [Result] Both activated carbon and macroporous resin can be used for decolorization. To be specific, macroporous resin-decolorization is superior in the yield and protein retention rate, while activated carbon-decolorization is superior in decolorization rate and decolorization operation process. [Conclusion] Macroporous resin-decolorization can be used if protein is the main ingredient required in the experiment, while activated carbon-decolorization can be used if protein is not the main ingredient required.展开更多

METHODS： Sixty and six patients with sepsis were assigned randomly to treatment group （32 cases） and control group （32 cases）. The extractfrom periplaneta americana plus conventional medication for sepsis was administered to the treatment group, while the control group only received conventional treatment. The gastrointestinal function scores and acute physiology and chronic health evaluation II （APACHE 11 ） scores of all subjects were documented at baseline, at days 1, 3 and 7 after treatment respectively and their blood endotoxin was tested at the same time points as well. The incidence of death was recorded for both groups throughout the trial. RESULTS： At days 3 and 7 after treatment, gastrointestinal function score, APACHE II, and endotoxin level in treatment group wasbetter than that in con- trol group and the difference between them was significant （both P〈0~05）. Although the incidence of death in treatment group was less than that in control group, the difference between the two groups was not significant （P〉 0.05）. CONCLUSION： The extract of periplaneta ameri- cana had protective effect on intestinal mucosal barrier and could improve the condition and prog- nosis in patients with sepsis.展开更多
