We established a new animal model of a genetic lipid storage disease analogous to human Wolman's disease. Affected Donryu rats, who inherited the disease in an autosomal recessive mode, manifested marked hepatosplenomegaly, lymph node enlargement, and thickened, dilated intestine. Morphologically, many characteristic foam cells Were observed in livers and spleens. No adrenal calcification could be found in affected rats. Biochemical studies on spleen and liver tissues showed massive accumulation of esterified cholesterol and triglycerides and deficiency of acid lipase for [^<14>C] -triolen, [^<14>C]-cholesterol oleate, and 4-methylumbelliferyl oleate.This animal model could contribute greatly to the clarification of the physiological and pathological roles of lysosomal acid lipase in the metabolism of lipoproteins and cholesterol, and of the pathogeneisis of atherosclerosis.

我们建立了一种类似于人类沃尔曼氏病的遗传脂质储存疾病的新动物模型。受影响的Donryu大鼠，他以常染色体隐性模式遗传了该疾病，表现出明显的肝肾上腺全球，淋巴结肿大，并增厚，扩张的肠道。从形态上讲，在肝脏和脾脏中观察到许多特征性泡沫细胞。在受影响的大鼠中找不到肾上腺钙化。对脾脏和肝组织的生化研究表明，酯化胆固醇和甘油三酸酯的大量积累以及[^<14> c] -triolen的酸性脂肪酶的缺乏，[^<14> c] - 胆固醇蛋白质的胆固醇和4-甲基近去的动物模型可以促进liperical carlipical carlipical carliepient and carlipical carlipical carlipical carlipical carlipical carlipedial carlized carlized carliepienation。在脂蛋白和胆固醇的代谢以及动脉粥样硬化病原体的代谢中。
