中药对脾虚仔猪胃蛋白酶和胰蛋白酶的影响

[目的]确定自拟的固肠促长散对脾虚仔猪胃蛋白酶和胰蛋白酶的影响。[方法]采用给仔猪注射利血平和交替不喂与喂饱的方法构建脾虚仔猪模型,分别在注射利血平前、最后一次注射利血平当天、灌药结束后次日及第8天测定仔猪的胃蛋白酶活力和胰蛋白酶含量。[结果]试验结束后,固肠促长散组的各种酶活性与正常对照组差异不显著,脾虚对照组和思密达组的各种酶活性与正常对照组差异显著。[结论]固肠促长散能促进利血平所致脾虚仔猪的胃蛋白酶活力和胰蛋白酶恢复。

银杏叶复方对脾虚性断奶仔猪肠黏膜形态、上皮淋巴细胞和杯状细胞数量的影响

为研究银杏叶复方对脾虚性断奶仔猪肠黏膜形态、上皮淋巴细胞和杯状细胞数量的影响,试验选择25日龄健康断奶仔猪30头,随机分成3组,即银杏叶复方组、脾虚模型组和对照组,每组5个重复,每个重复2头。颈部注射利血平加饥饱失常法建立脾虚性腹泻模型,银杏叶复方进行治疗。预试7 d后进行正式试验,试验期为30 d。结果表明:银杏叶复方组回肠绒毛高度显著高于脾虚模型组(P<0.05),十二指肠、回肠隐窝深度显著低于脾虚模型组(P<0.05);银杏叶复方组十二指肠绒毛高度/隐窝深度(V/C)显著高于脾虚模型组(P<0.05),回肠V/C极显著高于脾虚模型组(P<0.01);银杏叶复方组十二指肠杯状细胞数、空肠和回肠上皮内淋巴细胞数目显著高于模型组(P<0.05)。可知,银杏叶复方有修复脾虚性断奶仔猪的小肠组织的作用。

Histological Effects of Guchangcuzhang Powder on Intestine and Spleen in Experimental Piglets with Spleen Weakness

[Objective] This study aimed to explore the histological effects of Guchangcuzhang powder on intestine and spleen in experiment piglets with spleen weakness.[Method] The 12 piglets with diarrhea were divided into two groups,namely the Guchangcuzhang powder group and the control group,six in each.On two and eight days after the drug discontinuance respectively,three piglets were selected from each of the group and killed by bloodletting from the jugular vein.Afterwards,paraffin sections of intestine and spleen were made and stained by HE staining solution,followed by observation of the histological changes.[Result] The structures of intestine and spleen in piglets drenched with Guchangcuzhang powder restored or approachedto normal.[Conlusion] Guchangcuzhang powder has the function of healing piglet diarrhea.
