• 中文摘要： 當觀察Long-Evans株老鼠腎上皮細胞時，於線粒體的基質內發現絲狀內涵物，其具有兩種型態：其一呈平行排列，另一種其絲亦呈平行排列，但具有明、暗帶的構造。 綜合各種不同切面的顯微照片觀察，發現此絲狀體均由直徑約 5nm 的絲平行成束排列而成。具明、暗帶結構的絲狀體，由高倍的顯微照片顯示其絲與絲之問有電子密度大的物質介入而呈現暗帶，反之若無此物質介入的區域則為明帶。
• 英文摘要： Two types of filamentous inclusions havebeen found within the matrix of mitochondriain the epithelial cells of uriniferous tubules inthe rat of Long-Bvans strain. One type of theinclusions is composed of a bundle of parallelfilaments 5nm thick; the other consists of anaccumulation of filaments having the same thick-ness as the former and with regular light anddark bands of 30.5nm periodicity. Their mor-phological characteristics are essentially similarto those of the intramitochondrial inclusionsreported by Suzuki in cells of thick limb ofHenle in Sprague-Dawley rats. Additionally, microcylinders, which were firstreported by Lin in pinealocytes of Long-Evansrats, have been observed within the mitochondrialcristae of the renal epithelial cells. They mayoccur in the same mitochondrion as the fila-mentous bodies, but no relationship is foundbetween both distict types of mitochondrialinclusions.
