pubmed-article:2385751 | pubmed:abstractText | Adult healthy specimens of Channa punctatus (fish) were exposed to three doses (i.e. 2.25, 4.50 and 9.00 Gy) of gamma radiations from a 60Cobalt source. Five animals were autopsied at each post-irradiation intervals of 1, 2, 3, 7 and 14 days. The liver was fixed in Bouin's fluid and after processing in a routine way, it was examined histologically and compared with control group. The radio lesions appeared on day 2 in 2.25 Gy dose group and on day 1 in 4.50 and 9.00 Gy dose groups. Signs of recovery was seen on day 7 in 2.25 Gy dose group. Liver exhibited normal picture on day 14 in 2.25 and 4.50 dose group but in 9.00 dose group the lesions persisted. The radiation effects were found dose dependent. | lld:pubmed |
