RESUMO
Objective:In oder to investigate the effect of Chuanmingshen violaceum polysaccharides ( CVP) and Solfated Chua-nmingshen violaceum polysaccharides ( SCVP) on immunosuppression induced by cyclophosphamide ( CY) in mice.Methods: CY were used to induce immunosuppression in mice;Spleen and thymus indexes were used to evaluate the immune organs indexes;the [3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltet-razolium bromide,MTT] method was used to detect the proliferation of spleen lymphocytes of each group;the concentrations of IFN-γand IL-2 were assayed by ELISA kit.Results: SCVP and CVP could resist immunosuppression by promoting lymphocyte proliferation, increasing the contents of IFN-γ and IL-2, promoting immune organs development in immunosuppressive mice induced by CY.Conclusion:SCVP and CVP exhibited the potential to used as immunopotentiator.
RESUMO
OBJECTIVE To understand operating room management conditions and put forward improvement methods at township hospitals.METHODS An observatory study was conducted in 9 township hospitals using the evaluation criteria based on the requirements of the Guidelines for Disinfection in Hospitals.Technical Guidelines for Prevention and Control of the Hospital Infection in Operation Departments and the Guidelines for Hand Hygiene of Medical staff in Medical Institutions.RESULTS Problems were found to a different extent in all of the 9 township hospitals:faults in rules and regulations,unreasonable layout technological process,unstandardized sterilization and disinfection and short knowledge about hospital infection.CONCLUSIONS Special attention to managment of operating room,improving consciousness,strengthening medical staff study and improving system are the key issues for improving the management level of operating room at township hospitals.
