| Apoptosis in colonic crypt epithelial cells was measured by observing the frequency of karyorrhexis and karyolysis in 1000 cells. |
| Frequencies of nuclear abnormalities other than micronuclei, such as binucleates, karyorrhexis and karyolysis, were also evaluated. |
| Nucleolar damage of photoreceptors that occurred after exposure include an early stage of nucleolar condensation, karyolysis, pyknosis, and karyorrhexis. |
| Nuclear pyknosis, karyolysis and eosinophilia of the cytoplasm of the necrotic centrilobular hepatocytes, and vascular congestion have also been observed. |
| Within the epiphysis of most sections, trabecular bone is frequently hypereosinophilic, and there is karyolysis and loss of osteocytes. |
