ABSTRACT

<p><b>BACKGROUND</b>Allergic asthma is a chronic airway inflammatory disease partly characterised by high concentration of T help 2 (Th2) cytokines in bronchoalveolar lavage fluid (BALF). There is no report on the relation of peripherally circulating blood lymphocytes and asthma. We explored the balance of Th2/Th1 cytokines in asthmatic mice. Exogenous recombinant interleukin (IL) 33 acted on murine peripheral circulating blood lymphocytes, IL-5 cytokine was selected for assessing Th2 cytokines and interferon-gamma (IFN-γ) for Th1 cytokines.</p><p><b>METHODS</b>Female specific pathogen free BABL/c mice were sensitised by intraperitoneal injection of 20 µg of ovalbumin emulsified in 1 mg of aluminium hydroxide gel in a total volume of 200 µl, and challenged for 30 minutes in 7 consecutive days with an aerosol of 2 g ovalbumin in 100 ml of PBS. Then we collected BALF and isolated lymphocytes from the peripheral blood. The lymphocytes were divided into two groups: asthmatic group and normal group. Th1/Th2 cytokines was detected by enzyme-linked immunosorbent assay (ELISA) kits.</p><p><b>RESULTS</b>In the asthma group, we found numerous eosinophils and lymphocytes on the glass slides. We then confirmed that the optimal concentration of IL-33 was 10 ng/ml and time of IL-33 stimulating lymphocytes was 24 hours. In the asthma group, the production of IL-5 was significantly increased over normal group after stimulation with IL-33 (P < 0.05) and the production of IFNγ was supressed from IL-33 stimulated lymphocytes (P < 0.05).</p><p><b>CONCLUSION</b>IL-33 acts on lymphocytes of peripheral blood increasing secretion of Th2 cytokines and inhibiting secretion of Th1 cytokines.</p>

ABSTRACT

Objective To study pharmacological mechanism of Sanshanxiao granules in treating diabetes. Methods The rat model of diabetes was set up by injecting STZ intraabdominally. The modeled diabetic animals were divided into model group, Sanshanxiao group, and Xiaokewan control group. Normal rats were devised as blank-contrasted group. It was observed through several aspects on the level of blood sugar and insulin, activity changes of SOD in serum, contents of MDA and changes of islets of pancreas morphologic contrastly. Results Sanshanxiao granules can reduce blood sugar, stimulate insulin secreted, develop activity of SOD and decrease the contents of MDA obviously (P

ABSTRACT

Objective: To study the effects of the treatment of burning mouth syndrome with millimeter wave through cave. Methods: Sixty four patients with burning mouth syndrome were divided into 2 treatment groups of millimeter wave and seal of tongue nerve. Before and after treatment the burning scope of the patients was recorded and analysed statistically. Results: The burning scope in the patients treated with millimeter wave decreased significantly compared that in those with the seal of tongue nerve ( P
