摘要

在一只致命的疟疾大鼠身上研究了脑、肺和肾的受累情况。Lewis近交系大鼠感染伯氏疟原虫K173。这种疾病在10-14天内被证明是致命的。寄生红细胞在第10天增加了43%,红细胞压积从50%下降到12%。收缩压从99降到56毫米汞柱。乳酸脱氢酶活性达到2543 U/l。BUN和血清肌酐在病程中翻倍。转氨酶升高10倍,胆碱酯酶由943 U/l降至271 U/l。肾脏形态学显示免疫复合物肾小球肾炎,肾小管间质系统正常。光镜下脑、心、肺检查正常。明显的贫血和休克是上述标本大鼠的主要死亡原因,这表明该疾病的病程与人类恶性疟原虫致命感染有显著不同,后者表现出严重的肺、肾和脑并发症。

Causes of death in lethal rat malaria.

The involvement of the brain, lungs and kidneys was studied in a lethal rat malaria. Lewis inbred rats were infected with Plasmodium berghei K173. The disease proved fatal within 10-14 days. Parasitaemia showed an increase of up to 43% parasitised red blood cells on Day 10 p.i. The haematocrit decreased from 50% to 12%. The systolic blood pressure dropped from 99 to 56 mmHg. The lactate dehydrogenase activity rose to 2,543 U/l. BUN and serum creatinine doubled during the course of the disease. The transaminases increased tenfold and the cholinesterase decreased from 943 U/l to 271 U/l. Morphologically the kidneys showed an immune complex glomerulo-nephritis with a normal tubulo-interstitial system. The brain, heart and lungs were normal by light microscopic examination. Marked anaemia and shock were the main causes of death in the above-mentioned specimen rat, showing that the course of the disease is significantly different from lethal infections in humans with Plasmodium falciparum who show severe pulmonary, renal and cerebral complications.
