Ultrastructural And Cytochemıcal Study On Intramıtochondrıal Granules Of Tubulus Proxımatıs Cells In Renal Cortex
Abstract
Electron microscope shows dense granules against electrons in the matrix of mitochondria (tintramitochondrial granules), The structural and functional characteristics of intramitochondrial granules are still a matter of debate. It has been suggested that they are related to ion transport into the cell (11, 6) or that some ions settle and accumulate on them (2, 4), that their structure is mainly composed of neutral lipids (8), and that they are phospholipids (12). In this study, the structure of intramitochondrial granules of the renal cortex proximal tubule and their relationship with the accumulation or transport of some cations were examined at the electron microscopic level with a cytochemical approach. For this purpose, the identification of lipid content, 2 - Enzymatic hydrolysis of nucleic acids, 3 - Removal of some ketones, 4 - Introduction of some divalent cations
