ABSTRACT
OBJECTIVES:
This study investigated serum sialic acids for a predictive and diagnostic biomarker of diabetes mellitus (DM) in dogs and its prognostic value with ethanolic extract of Anogeissus leiocarpus.DESIGN:
Four groups of 3 dogs were used; non-diabetic controls (ND), diabetic-untreated (DU), diabetic insulin-treated (DI) and diabetic extract-treated (DE). Free serum sialic acids (FSSA) and erythrocyte surface sialic acids (ESSA) were assayed in all groups, pre-and post-induction of hyperglycaemia and results were presented as means ± standard error of means (SEM) and subjected to ANOVA using Tukey's post-hoc tests with GraphPad Prism® statistical package.RESULTS:
FSSA increased in DU and plateaued at third week (61.8 ± 0.41 µg/ml), (P < 0.002) with additional 38.2 µg/ml (62%) generated, coinciding with hyperglycaemia. FSSA of DI increased but declined to 22.3 ± 1.55 µg/ml. Extract of Anogeissus leiocarpus effectively modulated FSSA in DE as increased value declined to 21.4 ± 0.78 µg/ml. Pre-induction DU ESSA (8.27 ± 0.11 µg/ml) significantly (P < 0.002) decreased by third week (2.33 ± 1.49 µg/ml), coinciding with hyperglycaemia. Strong negative correlation coefficient (r = -0.92) occurred between DU's FSSA and ESSA and ND (P < 0.03). Sialic acid expression in dog's insulin dependent diabetes mellitus (IDDM) is 18% lower than normal. Extract of A. leiocarpus restored ESSA completely. ESSA cleaved in DU, 5.94 µg/ml (72%), could not account for the extra FSSA (32.26 µg/ml); liver and kidneys are contributors.CONCLUSION:
FSSA predicts canine DM.
