Abstract
The liver capsule measured 28.08 in goat and 18.62 in sheep. It was surrounded by a layer of flattened mesothelial cells. It was composed of collagen, elastic and reticular fibras and occasional smooth muscle. The liver capsule indicated intense reactions for bound protein and DMA moderate to weak reactions for PAS positive substances, glycogen, bound lipid, acid mucopolysaccharides and calcium salts in both the species: however reactions for PAS positive carbohydrates and alkaline phosphatase ware of higher intensity in sheep, whereas, a negative reaction was noted for alkaline phosphatase in the liver capsule of goat. Reactions for natural fats, MA, acid phosphatase and ferric iron were found to be absent.
Stromal connective tissue contained scanty amount of elastic, collegen fibres and abundant of reticular fibros. The fibroblasts vara comparatively more in the stronal tissues of the sheep. Stromal connective tissus showed intansa reactions for bound protein and DNA moderate to weak reactions for glycogen/ bound lipid, acid mucopolysaccharides and calcium salts in both goat and sheep. The PAS positive carbohydrates and alkaline phosphatase activity in the stromal connective tissus was of higher degree in sheep. Noutral fats, MA, acid phosphatase and forric iron were found to be absent in both the cases.
