儿童特发性股增殖性肾小球肾炎（MPGN）也称系膜毛细血管性肾小球肾炎。本病早在1965年依靠有关光镜观察结果及血浆中C3下降而被认识。进一步的研究表明有些病人尽管有典型的病理组织学改变，但C。水平却正常。最近对肾小球超微结构的研究将MPGN分为3型。巨型也称致密物沉积病 Children’s idiopathic proliferative glomerulonephritis (MPGN) is also known as mesangial capillary glomerulonephritis. The disease as early as 1965 rely on the light microscopic observations and plasma C3 decreased and be recognized. Further studies have shown that some patients despite a typical histopathological changes, but C. The level is normal. Recent studies on glomerular ultrastructure have classified MPGN as type 3. Giant also known as dense sediment disease
