Abstract
|
|
|
Toxic nephropathy of various origin is increasingly requiring a new medical attention. The principal lesion of the disease is co isidered to be related to the changes of tubular systems but not the vasculatures. Here we have performed an experimental study to observe the changes of vascular systems as well as those of the tubules in experimentally induced intoxicated kidney with mercury bichloride.
Followings are results.
I . In micro3ngiography of the normal kidney interlobar artery, arcuate artery, interlobular artery and cortical brush are depicted well regularly. Interlobar artery measures 0. 9-1. 5 cm(average 1.22 cm) in length, arcuate artery 0.2-0.6 cm(average 0. 39 cm), cortex 0. 3-0.6 cm(average 0.43 cm) in thickness and medulla 0.4-1.4 cm(average 0.93 cm).
2. In the mercury bichlorida intoxicated kidney the intrarenal vascular system reveals no particular changes whereas destructive changes of the tubules and mild enlargement of the medulla are observed.
3. In the mercury bichloride intoxicated kidney treated with BAL, the intrarenal vasculatures and medulla are depicted normally if the BAL is given within 6 hours after the intoxication, while destructive changes of the tubules and enlargement of the medulla are found when the antidote is injected in 12 hours or more after the intoxication.
