Chinese Traditional Patent Medicine 1992;0(07):-
AIM: To prepare the asperosaponin—phospholipid compound to improve the bioavailability of asperosaponin in rat intestine in situ. METHODS: Ratio of asperosaponin to phospholipid was chosen as index to screen the optimal proportion based on the orthogonal design.Rat intestine perfusion was use to compare aspersaponin absorption under with and without phospholipid. RESULTS: Asperosaponin—phospholipid compound showed the markedly improvement in absorption capacity and absorption rate. CONCLUSION: The experiment recommends that asperosaponin in the combination with phospholipid is better than only used asperosaponin concerning bioavailability.

Objective To investigate the association between social support and family cohesion, adaptability of rural patients undergoing maintenance hemodialysis (MHD). Methods Between August 2012 and November 2012, 94 patients with incident hemodialysis from rural areas in Hebei province were consecutively recruited in the study. The social support inventory (SSI) and the Chinese version of the family adaptability and cohesion evaluation scales (FACESII-CV) were employed in the investigation 3 months after the start of hemodialysis. Pearson correlation analysis was used to estimate the relationship between social support and familiarity, adaptability in rural MHD patients. Results The score on the family cohesion the adaptability were lower than norm(all P<0.001). The social support was associated with family cohesion and adaptability. The total scores on social support, emotional support and material support were positively associated with the scores on the family cohesion and adaptability (P<0.05). Conclusions The family cohesion and adaptability in rural patients undergoing hemodialysis are both at a lower level and are closely related to emotional and material supports. The higher they get social support, the higher the levels in family cohesion and adaptability.

ObjectiveTo observe the neuroprotective effect of basic fibroblast growth factor(bFGF)on cerebral diffuse axonal injuries (DAI)of rats.Methods40 male SD rats were randomly divided into control group, DAI injury group, bFGF group and DAI saline group. According to the survival time of rats, DAI injury group were divided into five groups, the 6h, 12h, 24h, 72h and 7th day group, The changes of bFGF expression in cerebral cortex were detected by immunohistochemical method from 6h to 7d after DAI. Two hours before DAI, bFGF 10μl was injected into right ventricle in bFGF group. ResultsThe bFGF expression appeared at 6h after DAI, increased at 12h, reached the highest level at 72h, and kept in a high level at 7d.There were obvious differences between 72h group and other groups in DAI injury group (P<0.01),cerebral cortex neurons were obviously decreased by HE staining. In each time group,injured neurons were decreased in bFGF group combined with DAI injury group(P<0.05). ConclusionsbFGF has obvious neuroprotective effect on cerebral diffuse axonal injuries of rats.

Objective: To study the difference between the acid resistance of Streptococcus mulans Ingbritt C international standard strain and the acid resistance of LuxS mutant strain. Methods: Solutions of Streptococcus mulans standard strain and LuxS mutant strain with same density were prepared and cultured at pH 3. 5 to 7. 0 BH1 liquid for same period. Terminal growth situation was compared. After being acidized in pH 5.5 BHI liquid, the two strains were cultured at pH 3.0 BHI liquid. The acid tolerance responses of the two strains were compared. Results; (DAt pH 6.0 to 7. 0, the difference of growth between Streptococcus mulans standard strain and LuxS mutant strain was not significant at the same pH value, and the differences of bacterial growth situation under three different pH values were not significant. (1)At pH 4.5 to 5.5, the difference of growth between the two strains was significant. (2)At pH 3.0,the survival rate of LuxS mutant strain(0.006 5% )was significantly lower than the standard strain (0.078% ). (3)At pH 5.5, the survival rate of LuxS mutant strain(0.747% ) was lower than the standard strain(8.65% )by about 10 times after the pre-acidification. Conclusion; (4)At sub-lethal pH value, there is significant difference of aciduricity between Streptococcus mu-tans standard strain and LuxS mutant strain. The acid resistance of standard strain is stronger than that of LuxS mutant strain. The two strains both display the capability of acid tolerance responses. LuxS mutant strain is more sensitive to acid inactivation, but the capability of acid tolerance responses still exists.
