采用腹腔注射、口服、背部皮下注射给予小鼠不同浓度的黄芪多糖注射液,以研究其对小鼠脾脏和耐力的影响.试验结果表明:黄芪多糖注射液采用腹腔注射给药能明显增加小鼠脾重,在两组试验中,2%的APS组的小鼠脾指数分别为5.19、6.46,与对照组比较(3.25、4.59)差异都极显著(P＜0.01).采用口服和背部皮下注射给药,对小鼠的脾指数无明显影响.游泳试验表明,给药组小鼠的游泳时间均明显延长,其中腹腔注射2%的APS延长率达到94.14%. 相似文献

为了对陇西栽培蒙古黄芪（Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao）的优质高产和良种选育提供一定依据,本文采用垂直板聚丙烯酰胺凝胶电泳技术,对该地区栽培蒙古黄芪种子酯酶同工酶进行了研究。结果表明：该地栽培蒙古黄芪是一个复杂的异质群体;种子酯酶同工酶电泳技术是检验蒙古黄芪种内变异的一种有效手段。 相似文献

通过对沙打旺种植地的调查，发现有11科25属37种蜘蛛．7月上、中旬出现的优势种为印痕球蛛（Theridion impressum），7月下旬出现的有条纹花蟹蛛（Xysticus striatipes）和黑侏儒蛛（Meioneta nigra），8月下旬偶见有田野豹蛛（Pardosa agrestis），但在4块样地内，自8月初到9月初，优势种基本上为条纹花蟹蛛．分析了蜘蛛生物学特性、植被情况、土壤情况和人事活动对蜘蛛群落结构和优势种群消长变化的影响，分析的结果可为草地害虫的综合防治提供参考． 相似文献

Astragalus mongholicus (AM) derived from the dry root of Astragalus membranaceus Bge. var. mongolicus (Bge.) Hsiao is a widely used traditional Chinese medicine. The present study investigated the potential role of AM on renal fibrosis on a rat model of unilateral ureteral obstruction (UUO). We divided 48 Sprague-Dawley rats randomly into 4 groups: sham-operated group (Sham), untreated UUO group, AM-treated (10 g/(kg.d)) UUO group, and losartan-treated (20 mg/(kg.d)) UUO group as positive control. Haematoxylin & eosin (HE) and Masson staining were used to study the dynamic histological changes of the kidneys 7 and 14 d after operation. The expressions of fibronectin (FN), type I collagen (coII), hepatocyte growth factor (HGF), transforming growth factor-pi (TGF-βl), and a-smooth muscle actin (a-SMA) were analyzed by real-time polymerase chain reaction (PCR), immunohistochemistry staining, and Western blot. Results show that, similar to losartan, AM alleviated the renal damage and decreased the deposition of FN and colI from UUO by reducing the expressions of TGF-pi and a-SMA (P<0.05), whereas HGF increased greatly with AM treatment (P<0.05). Our findings reveal that AM could retard the progression of renal fibrosis. The renoprotective effect of AM might be related to inhibition of myofibroblast activation, inducing of HGF and reducing of TGF-β1 expression. 相似文献
