Background: Yellow‐headed temple turtles (YHT), Hieremys annandalii, native to Thailand, are protected from exploitation under the Wild Animal Reservation and Protection Act, also listed under Appendix II of the Convention on International Trade of Endangered Species and the International Union for the Conservation of Nature red list. Objectives: The objectives of this study were to describe quantitative, morphologic, and cytochemical features of blood cells and plasma biochemical analytes of clinically healthy YHT. Methods: Blood samples were collected from 40 adult YHT from October 2007 to February 2008. Hematologic and biochemical analyses, cytochemical staining, and ultrastructural evaluation were performed using standard methods. Results: Hematologic results (mean ± SD) included: RBC count, 0.275 ± .094 × 106 cells/μL; WBC count, 11.7 ± 6.6 × 103 cells/μL; heterophils, 29.4 ± 6.9%; eosinophils, 23.7 ± 5.3%; basophils, 21.2 ± 1.9%; lymphocytes, 14.8 ± 5.9%; and azurophils, 10.7 ± 5.3%. Erythrocytes stained dark red with peroxidase‐staining. Periodic acid‐Schiff stain could not differentiate between thrombocytes and lymphocytes. Thrombocytes contained cytoplasmic vacuoles, similar to mammalian platelets and those of birds and snakes. Heterophils and eosinophils were similar in structure and cytochemical staining characteristics to those of other turtles and reptiles. Structure of basophils was similar to avian basophils. Lymphocytes and azurophils had similar cytochemical staining compared with mammalian lymphocytes and monocytes. Mean MCHC, WBC counts, absolute azurophil counts, and plasma alanine aminotransferase activity were higher in male turtles than in females. Conclusion: Blood characteristics of YHT are species‐specific, and this study can be served as a reference for future clinical studies and medical care of YHT. 相似文献

The purpose of this study was to measure the thickness of canine epidermis at various anatomical sites according to localization of cornified envelopes (involucrin and filaggrin), keratins (keratin 10, 5), and their mRNA expression. This was done in the skin of five breeds of dogs including seven poodles, six golden retrievers, six Shih Tzus, four pugs, and four Labrador retrievers. Epidermal thickness of the stratum corneum and nucleated epidermal layer was significantly different. The greatest thickness was observed in the digital web area and the thinnest epidermis was in the axilla. Epidermal thickness was also significantly different between the breeds (p < 0.05). Immunohistochemical staining scores revealed significant decreases of involucrin, filaggrin, and keratin 10 in the ventral and weight-bearing sites, and a relative increase of keratin 5 (p < 0.05). q-PCR analysis showed that their the levels of mRNA were positively correlated with expression of the corresponding proteins in skin samples (p < 0.05). The present study is the first to report the relationship between epidermal gene expression and histologic morphology of the skin in normal dogs. Further studies will be essential to fully understand the pathogenesis of skin barrier dysfunctions in canines. 相似文献

The optimal dosage of astaxanthin for goldfish Carassius auratus was determined by feeding a series of diets containing 0, 25, 50, 75, and 100 mg of astaxanthin/kg of diet for 4 wk. The pigmentation on fish skin was measured by visual assessment against a color chart and by counting chromatophores produced in the dermis layer of fish skin. Both criteria showed that 36–37 mg/kg astaxanthin was the optimal dosage to stimulate fish color. A 4-wk observation after this experiment demonstrated that fish color stimulated by dietary astaxanthin was stable in its intensity. Therefore feeding astaxanthin could be a suitable way for goldfish producers to stimulate color among fish grown in an algae-free environment. The survival rate of fish fed diets with astaxanthin was significantly higher than fish fed diets without astaxanthin. However, there was no significant effect of astaxanthin on fish weight gain. 相似文献
