Jejunal biopsies were performed in 71 subjects, who were classified into three groups as follows: Forty-one patients, on a poor diet, without clinical signs of malnutrition, with and without parasitic infestation; nineteen patients with severe protein-calorie malnutrition, with and without parasitic infestation; control group, ten medical students and one of the authors on a normal diet and without parasitic infestation. The dissecting microscope appearance showed mild alteration of the intestinal villi of Group A patients with parasitic infestation and severe alteration on Group B patients, especially those with parasitism. On histological examination, only the total mucosal thickness showed statistically significant differences between the Group B (severe protein malnutrition) and the other groups.
对71名受试者进行了空肠活检，这些受试者被分为以下三组：41名患者，饮食不佳，无营养不良的临床体征，有或无寄生虫感染；19名患有严重蛋白质 - 热量营养不良的患者，有或无寄生虫感染；对照组，10名医学生和本文作者之一，饮食正常且无寄生虫感染。解剖显微镜下观察显示，A组有寄生虫感染的患者肠绒毛有轻度改变，B组患者尤其是有寄生虫感染的患者有严重改变。组织学检查显示，只有B组（严重蛋白质营养不良）与其他组之间的总黏膜厚度存在统计学显著差异。
