Objective:To study the effects of glucosamine(GlcNH2) on immune function in mice.Method:The effects of GlcNH2 on murine proliferation of splenocytes were carried out in vitro.After feeding mice by GlcNH2,the phagocytotic functions of mononuclear macrophage,murine delayed type hypersensitivity(DTH) caused by sheep red blood cells(SRBC),the ability of antibody production(tested by HC50),and the index of immune organs(thymus and spleen) were deteimined in vivo.Results:GlcNH2 could promote the proliferation of splenocytes,phagocytotic functions of mononuclear macrophage,DTH,the ability of antibody production and the index of immune organs.Conclusion:Glucosamine can enhance immune function in mice such as cellular immunity,humoral immunity and non-specific immunity.

OBJECTIVETo investigate the serum sE-cadherin level in patients with endometriosis and the alterations of that level in healthy control during the menstrual cycle.

METHODSThirty-two patients with endometriosis and 30 healthy women were tested for serum sE-cadherin levels by enzyme-linked immunosorbent assay.

RESULTSThe serum sE-cadherin levels in healthy control did not vary throughout the menstrual cycle, which were lower than those in patients with endometriosis.

CONCLUSIONSE-cadherin might be involved in endometrial shedding during menstruation in endometriosis patients. The serum sE-cadherin assay might be helpful as a serum marker for the diagnosis and management of endometriosis.

Objective To discuss the feasibility of Shuyisha as hemostasis and repair material for liver wound. Methods Hemolysis rate, acute toxicity and eytotoxicity of Shuyisha were measured. A hemorrhage model was established by making an open wound (5 mm× 3 nun ×2 mm) on the left liver lobe of mice. Hemostasis was performed with Shuyisha in experimental group and with Surgicel in control group, when the hemostatic time and total blood loss (TBL) were accurately recorded and regular macro-scopic and histological observation carried out. Results The hemolysis rate of Shuyisha was 2.33%, with maximum tolerance does of over 0.48 g/kg and the eytotoxicity at zero. The hemostatie time of Shuy-isha was (5.00 ±0.00) s, with total blood loss of (0.88±0.18) g/kg, better than Surgicel (P< 0.05). Shuyisha was degraded completely within 14 days, with the wound healed within 21 days in ex-perimental group, much better than Surgieel. Conclusions The hemolysis rate, acute toxicity and cy-totoxicity of Shuyisha are up to the requirement of biomedical materials. Shuyisha has effective hemosta-sis, which may be related to its molecular structure and adhesion.
