Immunoglobulins and complement are deposited in the glomerular mesangium of rats with progressive glomerulosclerosis secondary to chemically induced diabetes mellitus. Isotransplantation of a kidney from a rat diabetic for 6 mo into a normal recipient results within 2 mo in the disappearance of IgG, IgM, and beta(1)C from the mesangium and arrest or reversal of the light microscopic glomerular lesions. Kidneys isotransplanted from normal donors into diabetic rats developed mesangial matrix thickening and deposition of IgG, IgM) and beta(1)C in the mesangium. No glomerular changes occur upon transplantation of a normal kidney into a normal rat. These findings indicate that diabetic glomerular changes in the rat are reversible and are secondary to the diabetic state rather than to the inducing agent.
免疫球蛋白和补体沉积于化学诱导的糖尿病继发进行性肾小球硬化大鼠的肾小球系膜中。将糖尿病6个月的大鼠肾脏同种移植到正常受体中,2个月内系膜中的IgG、IgM和β(1)C消失,光镜下肾小球病变停止或逆转。将正常供体的肾脏同种移植到糖尿病大鼠体内,会出现系膜基质增厚以及IgG、IgM和β(1)C在系膜中的沉积。将正常肾脏移植到正常大鼠体内则不会出现肾小球变化。这些发现表明,大鼠的糖尿病性肾小球变化是可逆的,是糖尿病状态而非诱导剂所致的继发性变化。
