Clinical findings and lysosomal enzymes (LYE) in eight lumpy skin diseases (LSD) cows and same number of healthy ones were reported in Tal-El Baker village and Tal Alkabir centre, Ismailia province, Egypt. LSD began with fever, anorexia, skin lesions in form of nodules all over the body, which disappeared spontaneously or gathered to form large lumps. It was complicated with respiratory manifestation, corneal opacity, mastitis, dehydration and later on recumbency. It is noteworthy that the level of 3 LYE showed the same trend of significant reduction in acute stage of the disease (5 days after occurrence of LSD) probably due to injection of animals with a therapeutics dose of terramycin. Acid-phosphatase (ACP) enzyme is the sole that behaved very high significant increase in the serum in acute stage of LSD due to the damaged tissues caused by the virus. It underwent insignificant decrease in late stage of the disease (20 days after its occurrence) to restore the normal LYE level in control cows indicating recovery. Alpha-galactosidase (alpha-GAL) decreased perpetually by the progression of LSD because of the decreased bactericidal index which ist in concomitance with the secondary bacterial invader. N-acetyl-beta-glucosaminidase (beta-NAG) and beta-galactosidase (beta-GAL) in LYE had the same fluctuating manner. The activities showed very highly significant decrease in acute stage, followed by highly significant and significant increases (late LSD stage) respectively. The appreciable significant increase of beta-GAL may declare the effect of anorexia on LSD. In view of these findings, it can be postulated that LSD may be diagnosed and prognosed through LYE changes in the serum.

Sustained hyperleptinemia in normal rats induced by infusing a recombinant adenovirus containing the rat leptin cDNA (AdCMV-leptin) exhibited a remarkable reduction in food intake (AdCMV-leptin, 9.3 +/- 2.6 vs untreated, 20.6 +/- 1.0 g/day) and ablated body fat without any significant changes in wet weight of liver and left ventricle. In those hyperleptinemic rats, we found a 52% reduction in wet weight of salivary gland compared with that in the pair-fed AdCMV-beta-gal-treated rats, which received a recombinant virus containing the beta-galactosidase gene (AdCMV-beta-gal) and were fed on the same amount of food as had been consumed by the AdCMV-leptin-treated group on the previous day. Microscopic examination with hematoxylin-eosin staining revealed that atrophic change was induced in both serous and mucous gland only in the AdCMV-leptin-treated group, but not in the pair-fed controls. Thus, the atrophic changes in hyperleptinemic rats were due to neither a decrease of food intake nor disuse of the salivary gland related with anorexia. Our data suggested that size of the salivary gland was controlled, at lease in part, by "non-anorexic" effect of leptin.
