The authors studied the formation of giant 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 microliter/kg. 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 hydrazine injection. Those show attenuated portion, Y, U, or C shaped feature suggesting fusion or budding 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 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.
