Activities of Diagnostic Enzymes and Lipid Content in Camel (Camelus dromedarius) Blood Vessels

Abstract

Al-Qarawi A. A., H. A. Abdel-Rahman, S. A. El-Mougy: Activities of Diagnostic Enzymes and Lipid Content in Camel (Camelus dromedarius) Blood Vessels . Acta Vet. Brno 2002: 71: 19-22. A number of tissue enzymes are a valuable tool as diagnostic agents. Alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), creatine kinase (CK), glutamyl transpeptidase (GGP), lactate dehydrogenase (LDH), in addition to cholesterol and triglycerides are demonstrated to be constituents of some of the major camel blood vessels. Any damage to these blood vessels could result in a significant increase in serum values becoming a valuable diagnostic tool for vascular diseases. The enzyme activities in the blood vessels of the one-humped camel (Camelus dromedarius), were measured. The blood vessels were the aorta abdominalis, vena cava caudalis, arteria carotis communis, arteria coronaria dextra, vena jugularis dextra, arteria pulmonalis dextra, vena pulmonalis dextra, arteria renalis, arteria plantaris medialis dextra, vena plantaris medialis dextra. The results indicated extremely elevated activities of the enzymes ALP, ALT, AST, CK, GGT LDH (8.47, 300.93, 17.12, 1.71, 10.94 and 411.11 nKat⋅g‐1, respectively) and lipids CHO and TG (12.03 and 6.9 mmol·g, respectively) in the a. coronaria dextra. At the same time there was no evidence for any difference between the arteries and veins. Thus, our results provides the first preliminary reference values of some diagnostic enzymes in the blood vessel wall that may be used when evaluating damage to the vasculature resulting in the leakage of the enzymes and lipids.
