The authors studied the formation of ginat mitochondria in liver cell. The Sprague
Dawley rats were sacrificed following intervals ; 5, 10, 20, 30, and 60 minutes after
intraperitoneal injection of hydrazine in the amount of 200 §¢/§¸. And the extracted liver
tissues were examined with light and electron microscopes.
The results obtained were summarized as follow ; Light microscopically, there is little
difference between control and experimental groups.
Electron microscopically, elongated, bizzare shaped mitochondria are appears 5 minutes
after hydrasine injection.
Those show attenuated portion, Y, U, or C shaped feature suggesting fusion or
budding of mitochondria. The number of giant mitochondria is decreased after 10
minutes group and rarely present in 60 minutes group.
The results suggest in this experiment that the formation of giant mitochondria is a
kind of reversible change and it is different from the mitochondrial swelling of cellular
injury.
Intermitochondrial fusion and mitochondrial budding may be related with the formation
of giant mitochondria.
