Objective To investigate the protective effect of pyrrolidine dithiocarbamate (PDTC) pretreatment on lung agaillst LPS-indueed injury in rats.Methods Fifty-four Wistar rats of both sexes weighing 180-220 g were randomly idivided into 3 groups:group I normal control(group C,n=6);group Ⅱ LPS (group L,n=24)and group Ⅲ PDTC(group P,n=24).Endotoxemia was induced by intraperitoneal LPS 8 mg/kg in group Ⅱ and Ⅲ.In group Ⅲ PDTC 120 mg/kg was injected iv at 30 min before IP LPS.Venous blood samples were collected at 1,3,6 and 12 h after LPS administration in group L and P and after normal saline administration in group C for determination of serum IL-6 concentration by ELISA.Six animals were killed at each time point after blood sample collection.The lungs were removed for microscopic examination and determination of W/D lung weight ratio,HSP70 expression and NF-κB activity.Results Intraperitoneal LPS significantly increased serum IL-6 concentration and W/D lung weight ratio,HSP70 expression and NF-κB activity in group Ⅱ.PDTC pretreatment significantly attenuated LPS-induced increase in serum IL-6 concentration,W/D lung weight ratio andNF-κB activity.The lung histologic dalnage induced by LPS Wag also ameliorated by pretreatment with PDTC.Conclusion Pyrrolidine dithiocarbamate pretreatment Can protect lung against LPS-induced injury through inhibition of activation of lung tissue NF-κB and up-regulation of expression of HSP70.

OBJECTIVE: To study the possible pathway of the effect of musk on brain disorder, distributing into the brain through blood brain barrier. METHODS: We used the musk ketone (muscone), a main composition of musk, to inject through the tail vein of the rats into the blood and took the brain and other organs at different times to make samples. Then gas chromatography was used to measure the distribution of muscone in the brain and other organs. RESULTS: Muscone could pass through the normal rat's blood brain barrier into the brain and soon reached the highest peak and remained in higher concentration, and more slowly metabolized as compared with other organs. CONCLUSION: Musk distributing into the brain through blood brain barrier provides the basis for its effect in treating brain disorders. Chromatography is an effective method to study the active composition of Chinese herbal medicine distributing through the blood brain barrier into the brain.

ObjectTo study the accumulation and distribution of dioscin in the different part of rhizome of Dioscorea zingiberensis C. H. Wright and the differences of its diosgenin. Methods Histochemistry has been used to study the accumulation and distribution of dioscin in the different part of rhizome and diosgenin was determined by HPLC. Results Dioscin distributed mainly in ground tissue. The amount of dioscin accumulated in the plant part from the region distributed with small vascular bundle (SVB) is the most abundant, and the diosgenin is also the highest in the same region; both of them in the region with no vascular bundle (NVB) are next to that of SVB; the amount of dioscin accumulated in the region distributed with big vascular bundle (BVB) is the lowest, and the diosgenin is the lowest in the same region too. Conclusion Diosgenin in every region of the three of male rhizome is higher than that of female rhizome and diosgenin in every region of the three of monoecism is between those of male and female rhizome.

This study is conducted to evaluate the protein quality of the spray-dried goat's milk powder made from milk of Qingdao's Laoshan dairy goats. Chemical analysis and rat experiment are included in the study with spray-dried powdered cow's milk and isolated soy protein as comparative substances and chemical pure casein as reference protein.The content of crude protein in the powdered goat's milk is 26.01% and the protein's limitting amino acid is sulphur containing amino acids with the AAS and CS being 0.91 and 0.52 respectively, similar to those of cow's milk protein. The percentage of EAA and the EAA index are 49.1% and 96.96%, as high as those of cow's milk. The results of the rat experiment designed according to AOAC showed that the PER, NPR, AD, TD, BV, NPU of the protein are 3.01, 4.62, 90.49%, 96.75%, 86.02 and 83.22% respectively. Except that the AD of goat's milk protein is slightly higher than that of cow's milk protein, there is no significant difference between two milk proteins on other nutritional parameters. The present study gives the conclusion that the protein of powdered goat's milk is at least as nutritious as that of powdered cow's milk, but more nutritious than chemical pure casein and far more nutritious than isolated soy protein.
