Abstract
|
|
|
|
Mitochondria was observed much around the nuclear membrane of liver tissue where the energy metabolism process is active. Testis tissue had a large number of undifferentiated cells, and cristae in Inner membrane of Mitochondria was not observed clearly. Morphological damage occurred first in Inner membrane rather than the outer membrane. The kidney tissue was clearly observed in the form of cristae. Radiation-induced damage occurred at the edges of both ends, and the membrane was observed bursting with the thickness of the outer membrane. Small intestine cells were observed in many mitochondria in the tissues around the villus, where bowel movements were active. Morphological damage occurred with the outer and inner membranes getting tangled. Mitochondria sensitivity to radiation was sensitized in testis and small intestine tissues, and kidney, ovary and liver tissues were found to be resistant.
