Resumen: | In the present study, we performed comparative histological observations of ICR, BALB/c, C57BL/6, C3H/HeN and DBA/2 mice kidneys. Sex and strain differences were observed in the appearance of vacuolar structures of the proximal convoluted tubules (toluidine blue-positive granules in osmium-postfixed epoxy-resin sections). These features were especially remarkable in male DBA/2 mice. The vacuolar structures in male DBA/2 mice showed heterogeneous staining with Sudan B in frozen sections and appeared under an electron microscope as multilammelar giant dense bodies. In addition, these dense bodies showed heterogeneous acid phosphatase reactions. Immunohistochemical analyses of these structures for apolipoprotein B showed strong positive reactions. These results suggested that vacuolar structures in the proximal convoluted tubules, which were remarkable in male DBA/2 mice, were giant lysosomes containing apolipoprotein B. |
