Densitometria óptica radiografia em equinos da microrregião da baixada maranhense

Abstract

The objective of this study was to determine the mineral density (BMD) of the accessory carpal bone using X-ray bone densitometry (DOR) in horses and the grouping Baixadeiro BMD values correlate with gender, age, calcium, phosphorus and alkaline phosphatase. To determine the degree of closure of the epiphysis of the distal radius, we used 60 animals were divided into two groups according to sex and aged between 18 and 30 months, under the regime of creating ultra-extensive. To this end followed by Stashak methodology 2002 that ranks the degree of closing the second phase of the development of plaque. We use portable, model FNX Jockey 90, chassis, displays and film size 24x30cm, craniocaudal projection and disclosure manual. To determine the values of BMD of the accessory carpal bone in mmAl, another 60 animals were radiographed, using the same equipment, projection lateromedial. It was adapted to a support frame made of wood and an aluminum coupled with 25 steps of each 3 mm. Radiographs were digitized using scanner Microtek ScanMaker 1000XL PRO model to be analyzed by Cromox v3.1 Vet Athena SAI - Advanced Intelligence System - (c) 2013. For the biochemical study was collected 5 mL of blood from each animal, this material was processed and analyzed using specific tests, following the manufacturer's instructions. The values obtained in this study was 2.86 ± 0.47 mmAl in males and 3.20 ± 0.77 in, females, with no significant difference between sex, macro minerals and enzyme studies but as the age of the animals. The epiphyseal plate closure was 26.7 months for males and 24.5 for females.
