ABSTRACT
Objective To study the effects of Glycyrrhiza polysaccharide (GP) on immune function in mice. Methods Polysacchayide was extracted from Glycyrrhiza uralensis by water-extraction-alcohol-precipitation method. Ovalbumin was injected to mice as antigens. The mice were randomly divided into four group:low (50 mg/kg), middle (100 mg/kg), high (200 mg/kg) dosage group of GP and normal control group, 12 mice in each group. Four groups were given GP and NS orally for seven days. After the secondary immunization, the level of antibody and the concentration of serum IFN-? were determined. Results The levels of antibodies and cytokines in middle and low dosage group of GP were all significantly higher than those of control group. Conclusion GP could enhance the immune function of mice.
ABSTRACT
Objective To explore the features of immune responsed activated by polysaccharides from herbal medicines and provide basis for immunomodulation of polysaccharides. Methods The mice were immuned by polysaccharides of Angelica, Atractylodes and Giant typhonium rhizome respectively, then the corresponeding antibodies and cross-reactive antibodies in serum were detected by ELISA. Results Three kinds of polysaccharides from herbal medicines could all activated the mice to produce not only the corresponding antibodies, but also the cross-reactive antibodies, the ranges of non-specific antibodies activated by distinct polysaccharide were different. Conclusions Polysaccharides from herbal medicines may be a kind of non-specific and broad-spectrum immunomodulators.
ABSTRACT
Objective To discuss dyadic fallopian tube of supermini underbelly cut windowing transplanting tiny simple skill wound method.Methods Choose 25 example mesenchymes headquarters or the gorge headquarter blocks nature barrenness(8 examples)and mesenchyme headquarter or gorge headquarter ectopic pregnancy(17 examples),adopt supermini underbelly 2.5 ~ 3.5 cm cuts to do dyadic fallopian tube of windowing transplant a skill,and transplant skill 15 examples action with the tradition fallopian tube contrasting.Results 25 example patients transplant 29 strip fallopian tube together,operation time shares 68.3 ?22.9 minutes,operation bleeding very few 35.8 +/-28.6 average mL,the skill queen is in hospital time 5.4 +/-0.8 days,no complication happens.Skill last 25 routine fallopian tube exchange the liquid experiment,17(68.0%)examples smooths,7(28.0%)examples exchanges but no free,1(4.0%)regular clausura.Conclusion That the supermini cut of underbelly and the dyadic fallopian tube of windowing transplanting skill is simple and microinvasive,which makes it worth extensive appeication.
ABSTRACT
Objective To explore the effect of endothelin (ET)、nitric oxide (NO) in plasma on retinopathy in the pregnancy-induced hypertension (PIH). Methods The level of ET and NO in plasma of 75 cases of in-patient women with PIH and 20 cases of women with the full terms and normal pregnancy before and after delivery was determined by radioimmunoassay. The retinopathy of the patients with PIH before and after delivery was detected by appointed doctor. The levels of ET and NO in both groups were compared and the relationship between ET and NO in plasma and the retinopathy before and after the delivery was detected. Results The levels of ET [(145.00?54.41) ng/L] in serious PIH patients were much higher than that in the control [(81.50?43.80) ng/L], the minor [(85.30?33.33) ng/L] and middling PIH group [(90.20?39.25) ng/L]. The levels of ET in plasma before and after pregnancy were not changed in PIH patients [(118.70?33.44) ng/L], but were higher than that in the control group. The levels of plasma NO in serious [(87.56?35.58) ng/L] and middling [(78.11?28.96) ng/L] PIH group were both higher than that in the control group [(46.70?32.64) ng/L], and the levels in minor[(52.56?28.35) ng/L] and middling PIH group were lower than that in the serious PIH group. The level of NO in plasma of PIH patients after the delivery was much lower than that before the delivery, while higher than that in the control. The positive correlation between levels of ET and NO and retinopathy was found in PIH patients. Conclusions The levels of plasma ET and NO in PIH patients are related to the extent of the disease, and the level of ET in plasma is highly related to the retinopathy in PIH patients. ET and NO might be played an important role in pathogenesis of retinopathy and ET might be a good index in reflecting the rank of retinopathy in PIH.
