ABSTRACT.-Gradela A., Souza V.N., Queiroz M.M., Constantino A.C., Bandeira C.G. This study aimed to evaluate the body biometry and hematological profile of Trachemys scripta elegans (N=28) and Trachemys dorbignyi (N=22) reared in captivity in the Brazilian submedium northeastern semi-arid region in the Valley of the São Francisco river. It aimed to establish basic health blood values and generate useful data on the comparative physiology of Testudines. After 120-day adaptation and 24-hour fasting, 2.5mL of blood were collected from the dorsal occipital sinus and deposited into a tube with sodium heparin for evaluation, following, of hematological levels. The red blood cell count (RBC) and GLC was conducted in a Neubauer chamber, the hemoglobin level (HGB) was supplied by the cyanmethemoglobin method and the hematocrit (HCT) was obtained by the microhematocrit technique. Based on the RBC, the hematimetric were mathematically established. Body biometry were also evaluated: a) body mass (BM, g); b) maximum dimensions of the carapace [length (MLC, cm) and width (MWC, cm)]; c) maximum dimensions of plastron [length (MLP, cm) and width (MWP, cm)]; d) total length of tail (TLT, cm); e) linear length from the base of the tail to the cloacal orifice (LPrC, cm); f) linear length from the cloacal orifice to the extremity of the tail (LPoC, cm). T. scripta elegans showed higher values (P<0.05) for biometrics, while TLT and LPrC were higher (P<0.05) in T. dorbignyi. The hematological values did not differ (P>0.05) among species. The results show that most of the variation found between T. scripta elegans and T. dorbignyi is explained by the biometric variables and that some hematologic correlations characterize interspecies differences. It was conclude that the results shed light on benchmarks for these species kept in captivity in the northeastern semi-arid region and serve as a model for intra and interspecies comparative physiology.

Description of absence of the distal part of the right thoracic limb in an individual of the species Corythomantis greeningi. Thereunto, it was performed radiographic evaluations in ventrodorsal projection followed by dissection of the piece and scanning electron microscopy. It was possible to verify in the radiograph that the affected limb still had the humerus. Scanning electron microscopy revealed irregularities, grooves, and fissures, typical of clipping fractures, which led to limb amputation. Considering the scarce literature, the importance of studies to distinguish malformations from those lesions that lead to the amputation of body segments is noted.

Resumo O estudo biomecânico de ligamentos articulares geram subsídios às pesquisas de biomateriais ou técnicas de tratamento para substituição ou reparação destas estruturas por ocasião de ruptura ou degeneração. Diante disto, realizaram-se ensaios biomecânicos de tração do ligamento patelar em 53 cães, totalizando 106 ligamentos patelares testados. Foram determinadas a capacidade máxima de resistência em Newtons (N) e a deformação expressa em milímetros (mm), sendo estes dados correlacionados à biometria corporal dos cadáveres dos cães utilizados. A resistência do ligamento patelar direito e esquerdo no grupo das fêmeas foi de 642,6N ±297,2N e 627,0N ±300,6N (p=0,028), respectivamente. Nos machos, verificaram-se valores superiores (p=0,035). O ligamento patelar direito teve capacidade máxima de resistência de 850,8N ±299,9N e o esquerdo 729,3N ±283,5N. Estatisticamente, foi evidenciado que não há correlação significativa (r>0,7) entre os parâmetros biométricos corporais aferidos e a resistência ou deformação do ligamento patelar. Mesmo não havendo correlação estatística significativa, os dados de resistência e deformação do ligamento patelar canino podem gerar embasamento para outras pesquisas, que visam corrigir rupturas de ligamentos articulares.
