目的:研究乐食宝咀嚼片治疗厌食症的药理作用.方法:大鼠随机分6组,每组10只,采用特制饲料喂养4周建立幼龄大鼠厌食症模型,从第8天起,每日给予乐食宝咀嚼片0.60,0.30,0.15 g·kg-1,连续3周,期间观察大鼠一般状况并记录体质量和饮食量;测定胃液量、游离酸度、总酸度和胃蛋白酶活性;取血清采用测试盒方法测定总蛋白(TP)、白蛋白(Alb)、总胆固醇(TC)、胃动素(MTL)和胃泌素(GAS)的含量;以0.80,0.40,0.20 g·kg-1剂量给予小鼠7 d,观察各组小鼠胃甲基橙排空率和小肠墨汁推进长度.结果:乐食宝咀嚼片可明显增加幼龄厌食模型大鼠体质量和饮食量(P<0.05或P<0.01);促进胃液分泌和提高胃液中总酸及游离酸含量(P<0.05或P<0.01);能明显提高幼龄厌食模型大鼠胃蛋白酶活性(P<0.05或P<0.01);显著降低大鼠血清中TP、Alb及TC含量(P<0.05或P<0.01);升高血清中MTL和GAS水平(P<0.05或P<0.01).同时能促进小鼠胃排空及小肠推进运动(P<0.05或P<0.01).结论:乐食宝咀嚼片可明显增加厌食症模型大鼠的摄食量和体质量,增强消化功能,对厌食症模型幼龄大鼠具有明显的治疗作用.“,”Objective:To study the pharmacological effects of Leshibao chewable tablets for juvenile rats with anorexia. Methods:The rats were divided into 6 groups with 10 ones in each and fed with special forage for 4 weeks to establish the anorexia model of ju-venile rats. After the model establishment, from the 8th day, the treatment groups received Leshibao chewable tablets respectively at the dose of 0. 60, 0. 30 and 0. 15 g·kg-1 ·d-1 for three weeks. The general situation was observed, and the appetite and body weight were recorded during the treatment. At the end of experiment, the gastric juice amount, free gastric acidity, total gastric acidity and pepsin activity were determined, TP, ALB, TCHO, MTL and GAS were determined by kit methods. Additionally, the mice were given Leshibao chewable tablets at different doses (0. 80, 0. 40, 0. 20 g·kg-1 ·d-1 ) for 7 days, the effects of Leshibao chewable tablets on gastric emptying and intestinal propulsive function were observed. Results: Leshibao chewable tablets could significantly increase the body weight, appetite (P<0. 05 or P<0. 01), gastric juice amount, free gastric acidity , total gastric acidity and pepsin secretion (P<0. 05 or P<0. 01), significantly reduce TP, ALB and TCHO in serum (P<0. 05 or P<0. 01), significantly increase MTL and GAS contents (P<0. 05 or P<0. 01), and significantly promote gastric emptying and intestinal propulsion in mice (P<0. 05 or P<0. 01). Conclusion:Leshibao chewable tablets can significantly increase body weight and appetite, and improve digestive function re-markably, which exhibit excellent therapeutic effect in the anorexia model of juvenile rats.
