  • Experimental Study on Effect of Salvia Miltiorrhiza and Shengmai Injection in Treating Systemic Inflammatory Response Syndrome

    【Abstract】ObjectiveTo investigate the effect of Salvia Miltiorrhiza (SM) and Shengmai injection (SI) in treating systemic inflammatory response syndrome (SIRS) and their mechanism. Methods The animal model of SIRS was established by injectinglipopolysaccharide(LPS, 1 mg/kg)intraperitoneally. Forty Wistar rats were randomly divided into four groups: control group, SM group, SI group and combined treatment group (SM+SI group), which were treated with normal saline(5 ml/kg) plus LPS(1 mg/kg), SM(5 ml/kg)plus LPSKG4(1 mg/kg), SI(5 ml/kg)plus LPS(1 mg/kg), SM(2.5 ml/kg) plus SI(2.5 ml/kg) and LPS(1 mg/kg) respectively. Six rats of each group were sacrificed for sample collection of blood, liver, lung and kidney 8 hours after LPS injection. Blood routine, serum TNF-α and IL-6 were measured. Specimen of organs were fixed in formalin and sent for routine pathological examination. The survival of other 4 rats of each group were observed untill 48 hours after LPS injection. SPSS 10.0 was used in statistical analysis. Results Two rats in control group died 13 hours and 22 hours after LPS injection respectively, the remaining 2 rats in this group and the rats in other 3 groups survived 48 hours after LPS injection. The white blood cell count of control group was significantly higher than that of other groups. The serum TNF-α and IL-6 of control group were significantly more than those of other groups. Pathological damages were found in all groups, and the most severe ones were in control group. SM and SI could decrease the level of serum TNF-α and IL-6 in the process of LPS-stimulated SIRS, down-regulate the severe inflammatory response, attenuate organ damages of the liver, lung and kidney, and increase forty-eihgt-hour survival rate obviously. Conclusion The experiment provides a theoretical base for clinical use of SM and SI in treatment of SIRS.

  • IMMUNE RESPONSE IN PIG TO MONKEY VESSEL XENOTRANSPLANTATION

    Objective To investigate the mechanism of hyperacute rejection (HAR) in pig to rhesus monkey vein xenograft. Methods Porcine femoral vein was transplanted into rhesus monkey. Deposits of IgM, IgG, C3 and C4 on the grafts were observed by immunoflurescence. Results Great deal of IgM, C3 and C4 were seen along the endothelium of donor vein, but IgG was not seen. ConclusionIn pig to monkey xenograft model, HAR is intiated by the binding of xenoreactive IgM to donor xenoantigens and followed by the activation of complement via the classical pathway.

  • APPLICATION OF SLEEVE ANASTOMOSIS IN DEVELOPMENT OF CERVICAL HEART TRANSPLANTATION IN RATS

    Objective To simplify surgical technique andincrease postoperative survival rate, sleeve anastomosis technique combined cuff technique was used in developing the model of cervical heart transplantation in rats. Methods In this model, the hearts from 25 male SD rats were transplanted into the neck of Wistar rats by anastomosing the donor innominate artery to the recipient right common carotid artery by use of sleeve technique, and the donor pulmonary artery to the recipient right external jugular vein by use of cuff technique. After operation,the rats were treated with cyclosporine A (1.5mg/kg, q.d.), transplanted hearts were followed by daily inspection or palpation and the allograft survival time was more than 3 days as the standard of successful operation. Results The mean operative time was (48.7±3.4) min, with a successful rate of 88%(22/25). Complications were anastomotic hemorrhage( 1 case) and thrombosis(2 cases). During the followup period, 6 rats died of pulmonary infection, abscess in the neck,liver or bladder tumor. The remaining 16 transplanted hearts survived more than3 months. Conclusion The modified operation have advantages ofless operative procedure, shorter operation and ischemia time and easier monitoring of graft function. 

  • GRAFT VERSUS HOST DISEASE AND XENOTRANSPLANTATION

    OBJECTIVE The pathogenesis, mechanism, manifestation and diagnosis of graft-versus-host disease(GVHD) are reviewed in this article. METHODS The relevant articles in recent public magazines were reviewed and summarized. RESULTS It was indicated that GVHD occurred in the conditioned recipients in animal experiments and clinical transplantations. Humoral and cellular factors were involved in GVHD, which could be diagnosed and classified according to their characteristics. CONCLUSION As a kind of interactions between the host and donor, GVHD are severely harmful to the host. It may also occur in xenotransplantation, where GVHD can be utilized in the studies on transplant immunology, oncology etc. Xenogeneic GVHD is receiving more and more attentions.

  • Effects of Sanqizonggan on Bacterial Translocation in Rats with Acute Necrotizing Pancreatitis

    【Abstract】Objective To study the effects of Chinese traditional medicine Sanqizonggan on bacterial translocation in rats with acute necrotizing pancreatitis (ANP).Methods The rat model of ANP was established by retrograde bilepancreatic duct injection of 5% sodium taurocholate. All rats were randomly divided into three groups: the shamoperation group(n=30), ANP group(n=30), and ANP+Chinese traditional medicine group (n=30). The serum amylase was detected at 0 h,12 h,24 h, and oneweek survival rate and pancreatic histological changes were observed in three groups, and the bacterial translocation from intestinal lumen was examined. Results The survival rate of the group treated with Chinese traditional medicine was significantly higher than that of the ANP group. The rate of bacterial translocation in the treated group significantly decreased. Conclusion The Chinese traditional medicine Sanqizonggan can promote gastrointestinal movement, protect intestinal mucosa and reduce bacterial translocation from intestinal lumen.

  • Influence of Radix Salviae Miltiorrhizae Injection upon NF-κB in Rat with Severe Acute Pancreatitis

    Objective To investigate the mechanism of radix salviae miltiorrhizae (RSM) injection in treatment of pancreatitis through observing the changes of activity of nuclear factor-kappa B (NF-κB) in pancreas of rats with severe acute pancreatitis (SAP) and the influence of RSM injection upon NF-κB in pancreas tissue. Methods Seventy-five rats were randomly divided into 3 groups: normal control group, SAP group and RSM treatment group, which were injected with normal saline, normal saline or RSM in the peritoneal cavity, respectively. The model of SAP rats was made by injecting L-arginine into peritoneal cavity and by subcutaneous injection at the same time. The concentrations of amylase in plasma and in ascites were measured respectively, and the expression of NF-κB in pancreas tissues was determined by immunohistochemistry. Results The levels of amylase in plasm and ascites in SAP group and RSM treatment group increased significantly with the increased expression of NF-κB in pancreas tissue, but it was also found that both the level of amylase and the expression of NF-κB in RSM treatment group were significantly lower compared with those in SAP group, and the survival time of RSM treatment group was longer than SAP group with less pathological injury in the pancreas tissues. Conclusion RSM may be effective for the treatment of pancreatitis by degrading the expression of NF-κB.
