“…In the summer, there were a significant increase in AST (p < 0.05) and a decrease in uric acid (p < 0.05) (Table 1). The other variables did not change in the analysed period, similarly to a variety of snake species evaluated pre-and post-hibernation (Francisco et al, 2002).…”

“…To our knowledge, there are not reference values of biochemical profile and serum protein electrophoresis for the subspecies Boa constrictor amarali (Stull, 1932). In addition, seasonal effects on biochemical profile have been poorly understood and scarcely reported in the literature, especially regarding South American snakes (Francisco et al, 2002).…”

Seasonal influence on biochemical profile and serum protein electrophoresis for Boa constrictor amarali in captivity

Similarly to other reptiles, snakes are ectothermic animals and depend exclusively on the environment for the maintenance of their physiological, biochemical and immunological processes. Thus, changes in biochemical values can be expected due to seasonal influence. Twenty-two adult specimens of Boa constrictor amarali kept in captivity were used. Blood collections were done in two different seasons: winter (July 2004) and summer (January 2005) for the following assays: uric acid, aspartate aminotransferase (AST), glucose, cholesterol, total protein, and serum protein electrophoresis. The mean biochemical results found in summer and winter, respectively, were: 6.3 ± 3.4 and 11.3 ± 6.2 mg/dL for uric acid; 28.7 ± 12.4 and 20.7 ± 16.2 UI/L for AST; 26.3 ± 17 and 17.4 ± 6.8 mg/dL for glucose; 67.3 ± 30.2 and 69.7 ± 38.5 mg/dL for cholesterol; and 5.9 ± 1.6 and 5.9 ± 1.4 g/dL for total protein. Results regarding electrophoresis in summer and winter, respectively, were: 1.9 ± 0.7 and 2.4 ± 0.6 g/dL for albumin; 0.7 ± 0.2 and 0.5 ± 0.2 g/dL for α-globulin; 1.5 ± 0.5 and 1.7 ± 0.6 g/dL for β-globulin; and 1.8 ± 0.5 and 1.5 ± 0.5 g/dL for γ-globulin. In the summer, there was a significant increase in AST and a decrease in uric acid (p < 0.05). Serum protein electrophoresis showed a significant increase in α-globulin fraction (p < 0.05) in the same season. There were not significant differences between seasons for the remaining variables. Based on these results, the period of the year must be considered in the interpretation of some biochemical values for these animals.
