The fat appearance was recovered on the 18th day of incubation. Necrobiosis of the liver cells and capillary hyperemia were also marked in OMP groups. Fat appeared also in vitamin B6 group.
2. Findings in the Kidney-Hyperemia in glomeruli and regressive changes in the epithelia of the urinary tubules were observed in OMP groups.
3. Findings in the Thymus-In both OMP groups and vitamin B6 group, anisocytosis, non-stainability and nucleus pycnosis of thymicolymphatic cells were detected, whereas no atrophy of the organ was observed.
