Morphological analysis of liver tissues of C. carpio exposed for acute and sub-lethal study. The morphological anomalies were represented in symbol based on their severity.
| Liver tissues morphological anomalies | Control | 96h | 7th | 14th | 21st | 28th | 35th |
|---|---|---|---|---|---|---|---|
| Nuclear degeneration | − | ++ | − | − | − | − | − |
| Vacuolization | − | ++ | − | + | + | + | − |
| Cellular edema | − | ++ | − | − | + | + | + |
| Increased sinusoidal space | − | ++ | + | + | + | + | + |
| Necrosis | − | + | − | − | − | − | + |
| Altered hepatocyte | − | + | − | + | + | + | + |
Note: The anomalies visible in the liver morphology were divided based on the severity into three grades (−) no anomalies; (+) anomalies in <20% of the fields; (++) anomalies in <20–60% of the fields.
