Xuangan Oral Liquid can increase blood platelets to a normal level in mice with thrombocytopenia induced by chemotherapy and radiotherapy. It was shown that Xuangan Oral Liquid can reduce blood coagulation time in mice through capillary and tail-cutting methods, and the difference between control group and treatment group is significant.

Objective To observe the effect of transfer factor on immunity in patients with varruca plana and the clinical effect of treatment. Methods Sixty patients with varruca plana were randomly divided into a treatment group (treated with transfer factor) and a control group (treated with routine therapy). Before and after the treatment, T-lymphocyte subgroups in peripheral blood of all the patients were determined by flow cytometry and serum levels of interleukin-10 (IL-10)and in-terferon-gamma (INF-γ)were detected by ELISA. The same detections were done to the twenty healthy volunteers as healthy controls. Results Effective rates in the treatment group and control group were 76.67 % and 43. 33 %, respectively (x2=5. 63,P<0.05). Decrease of CD3+ cells, CD4+ cells, CD4+/CD8+ ratio and increase of CD8+ cells were found in varruca plana group as com-pared with the healthy controls(P<0.01 ). After the treatment of transfer factor, increase of CD3+ cells ,CD4+ cells (P<0.05), CD4+/CD8+ ratio (P<0. 01)and decrease of CD8+ cells(P<0.01)were found in the treatment group as compared with those before treatment, while there were no significant difference in the control group before and after the treatment. Higher IL-10 and lower INF-γ in serum were found in varruca plana group as compared with the healthy controls (P<0.05). After the treat-ment of transfer factor, decrease of IL-10 and increase INF-γ in serum (P<0. 05)were found in the treatment group as compared with those before treatment, while there were no significant difference in control group before and after the treatment. Conclusion The results reveal that immunity is im-paired in patients with varruca plana. Transfer factor can enhance the immunity of the patients. Therefore, varruca plana patients treated with transfer factor receive better effects.

OBJECTIVETo investigate the effect of adrenomedullin (ADM) on renal arteriole remodeling and phosphorylation of extracellular signal-regulated protein kinases 1/2 (p-ERK1/2) in spontaneous hypertensive rats (SHR).
METHODSMale SHR (4 weeks old) were randomized into hypertensive group (SHR) and ADM-treated group (ADM) to receive subcutaneous saline and ADM injections (daily dose of 1.0 nmol/kg, 5 days a week), respectively, with age-matched Wistar-Kyota (WKY) rats as the blank control. The systolic blood pressure (SBP) was measured at the end of each week, and histological changes of the renal arterioles were observed using HE and Weigert staining; the expression of P-ERK1/2 in the arterioles was detected with immunohistochemistry and Western blotting.
RESULTSAt 16 and 24 weeks of age, the rats in both SHR and ADM groups showed significantly higher SBP levels than WKY rats (P<0.05), and at 24 weeks, SBP was significantly lower in ADM group than in SHR group (P<0.05). The intima thickness/lumen diameter (IT/LD) ratio of the renal arterioles increased in both SHR and ADM groups at 16 and 24 weeks as compared with that of WKY rats (P<0.05), and for arterioles with an outer diameter <40 µm, the IT/LD ratio was significantly lower at 24 weeks in ADM group than in SHR group (P<0.05). The renal expression of p-ERK1/2, which increased significantly in SHR and ADM groups at 16 and 24 weeks (P<0.05), was significantly lower in ADM group than in SHR group at 24 weeks (P<0.05).
CONCLUSIONSLong-term ADM treatment can control SPB elevation in SHR rats and reduce renal arteriole remodeling by inhibiting the phosphorylation of ERK1/2.
