Determination of proteins and metabolites concentrations in plasma of rattlesnakes in captivity

摘要

: For determining plasma concentrations of proteins and metabolites of rattlesnakes in captivity, 60 adult snakes, 30 males and 30 females were used. Blood was collected by puncture of the cervical paravertebral venous sinus and stored in tubes with heparin. Biochemical analyzes were colorimetrically processed using an Automatic Biochemistry Analyzer Chemwell (Awareness Technology??, Inc). The mean and standard deviation were calculated for the following constituents: total protein, albumin, globulin, albumin/globulin ratio, uric acid, creatinine, urea, cholesterol, HDL cholesterol and triglycerides. The values were similar to those previously reported for reptiles and snakes, with the differences observed probably due to the difference between species, climate, season and the methodology used. There were no significant differences between males and females for the parameters studied. These results may be useful in establishing normal biochemical values for conservation plans for these snakes in captivity. Index
