Objective: Determination of the reference values of aspartate aminotransferase (AST), alanine aminotransferase(ALT),
alkaline phosphatase (ALP), lactate dehydrogenase (LDH)
and gamma glutamyltransferase (GGT) in the urine of
clinically healthy Iranian dromedary camels.
Design: Descriptive study.
Animals: Fifty clinically healthy adult camels (Camelus
dromedarius).
Procedure: Urine samples were collected from fifty
clinically healthy adult camels in identical nutritional and
managemental conditions. urine specimens were
lyophilized and the activity of AST, ALT, ALP, LDH and
GGT was measured by routine colorimetric methods. Also, urinalysis and measurement of urine creatinine were
performed.
Statistical analysis: The data were analysed by analysis of
Variance (ANOVA), Duncan’s multiple range test and
regression analysis. Results: LDH and GGT showed the highest and the lowest activity of urinary enzymes were related to LDH and GGT,
respectively. Urine pH was alkaline. The concentration of
creatinine in the urine of Iranian camels was relatively
high. According to urinalysis, the urine of Iranian camels was normal. Significant positive correlations were
observed between GGT activity and urine creatinine
(P (P Conclusion: The activity of AST, ALT, ALP, LDH and
GGT in the urine of Iranian camels can be used as indices for diagnosing renal disorders. J.Fac.Vet.Med. Univ.
