Clinical Study on Treatment of Infantile Rotaviral Enteritis with Guava Leaf

Objective: To observe the clinical effect of guava leaf (GL) in treating infantile rotaviral enteritis.Methods: Sixty-two patients of rotaviral enteritis were randomly divided into the treated group treated with GL and the control group treated with Gegen Qinlian Decoction. The time for ceasing diarrhea, content of Na+ in blood, content of Na+ and glucose in stool, and the rate of negative conversion of human rotavirus antigen (HRVA) were observed.Results: The 3-day recovery rate in the treated group (87.1%) was significantly higher than that in the control group (58.1%, P<0.05). The time of ceasing diarrhea in the treated group (25.1±9.5 hrs) was significantly shorter than that in the control group (38.7±15.2 hrs, P<0.01). Moreover, content of Na+ and glucose in stool were reduced obviously in the treated group but not in the control group; and negative conversion rate of HRVA in the former group also got better than that in the latter group (87.1% vs 58.1%, P<0.05). Consequently, the effect of GL was superior to that of the control significantly.Conclusion: GL has good curative effect on infantile rotaviral enteritis.

番石榴叶治疗轮状病毒肠炎的实验研究

目的 :研究番石榴叶对小鼠轮状病毒 (HRV)肠炎的作用及其机制。方法 :选用发育正常的BLAB/C健康小鼠 12 0只 ,随机分为正常对照组、感染对照组、藿香正气口服液组、番石榴叶大(3.6 g/kg)、中 (1.8g/kg)、小 (0 .9g/kg)剂量组。按Schonb方法复制模型 ,于感染后 2 4h给药 ,正常和感染对照组灌服等容量 9.0 g/L氯化钠注射液 ,藿香正气口服液组 (1.6 2 g/kg)、番石榴叶小、中、大剂量组 ,每日灌胃 3次 ,每次容量为 2 0ml/kg ;疗程为 72h。比较藿香正气口服液、番石榴叶不同剂量对小鼠病死率 ,小肠黏膜病理变化 ,血、粪生化指标 ,SIgA含量 ,HRV抗原阴转率的影响。结果 :番石榴叶大、中剂量组能改善小鼠小肠黏膜组织的病理损伤及粪便中的SIgA含量、HRV抗原阴转率、血Na+ 、红细胞比容 (Ht微量法 )、粪Na+ 、粪糖含量、病死率 ,与番石榴叶小剂量组、藿香正气口服液组比较 ,差异有显著性 (P <0 .0 5 )。结论 :番石榴叶大、中剂量组是通过提高小鼠粪中SIgA含量和HRV抗原阴转率 ,促进小肠黏膜的修复 ,增加粪Na+ 、粪糖吸收 。
