中耳炎颞骨咽鼓管峡部粘-软骨膜的组织病理学观察

目的：了解中耳炎性病咽鼓管峡部粘－软骨膜的影响。方法：用光镜对３２耳各型中耳炎颞骨（中耳炎组）与５０耳正常颞骨（正常组）标本连续切片的咽这峡部粘－软骨膜,中耳腔鼓岬粘骨组织病理学比较观察。结果：中耳炎组和正常组颞骨标本咽鼓管峡部均无病理性阻塞;中耳炎组峡部粘－软骨膜厚度测量和病理观察,未见有明显炎症改变,与正常组比较无明显差异;而其中耳腔粘骨膜均明显炎症病变。这种炎症截然不同反应的界限恰好在咽这的     

Oral rehydration with a plantain flour-based solution in children dehydrated by acute diarrhea: a clinical trial

A clinical trial was conducted in order to prove the efficacy of a solution containing 50 g/1 of plantain flour and 3. 5 g/1 of sodium chloride (NaCl) for the rehydration of children with acute diarrheal diseases. 121 children were given WHO-ORS (Group A) and 117 a plantain flour-based solution (Group B). Rehydration was successful in 85. 9% in Group A and 88. 0% in Group B ( p = 0. 634). Rehydration was completed in 5. 28 h (SD 1. 99) in Group A and in 4. 88 h (SD 2. 11) in Group B ( p = 0. 132). The average solution intake for rehydration was 24. 56ml/kg/h (SD 10. 12) in Group A and 21. 17ml/kg/h (SD 9. 35) in Group B ( p = 0. 00782). The mean stool output during rehydration was 8. 45g/kg/h (SD 9. 72) in Group A and 4. 69 g/kg/h (SD 4. 98) in Group B ( p = 0. 00053). Decrease in blood levels of sodium and potassium occurred in some children in group B. The plantain flour-based solution proved effective for the treatment of dehydration due to acute diarrheal diseases and should be considered as an alternative when standard WHO-ORS is not available.
