 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Prenatal Development of Gonads in Siamese Crocodile Embryos (Crocodylus siamensis)) ผู้เขียน:วรรณดา สุจริต, ดร.อุไร พงศ์ชัยฤกษ์, ผู้ช่วยศาสตราจารย์, นางสาวผกาวดี พงษ์เกษ, Natanun Prompa, Pibul Ruengsupapichat, ดร.ศิริรักษ์ จันทครุ, ผู้ช่วยศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractIn crocodiles, differentaition of gonads to testis or ovary was influenced by incubation temperatures. To manipulate sexual outcome of the offspring, the information of gonadal development in terms of timing and stages of development is crucial. However, there has been no reports in Siamese crocodiles (Crocodylus siamensis), indigenous fresh water crocodiles of Thailand. This study aims to investigate gonadal development in Siamese crocodile embryos at 35, 48, 63 and 69 days of incubation which belonged to the second half of incubation. Microscopic study of gonad from Siamese crocodile embryos showed the presence of gonadal ridges in embryos at 35 days of incubation, Migration of primordial germ cells was found within gonads at day 35 of incubation and during the same period sex cords were developed. Bipotential gonads were detected at 48 days of incubation and sex cords extensively developed at 63 days and at 69 days of incubation. The data suggested that development of testis and ovary may occur after hatching. Expressions of sex steroid hormones and receptors for sex hormones in Siamese crocodile are needed to be elucidated. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Histological Study on Effect of Kapok Seed Meal and Kapok Seeds on Gonads and Livers in Broilers) ผู้เขียน:Supaluk Tiansuwan, Prateep Rachapaetayakom, ดร.กฤษณ์ มงคลปัญญา, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractHistological studies on gonads and livers of broilers after fed with a ration supplemented with kapok seed meal to replace 20% plant protein or kapok seeds to replace 10% plant protein for 8 weeks were carried out. Increase of stromal connective tissue and decrease of developing follicles were observed in the ovaries in comparison with the control. Proliferation of interseminiferous tubule counective tissue in testes of the treated animals was also revealed. The livers were affected with histological lesions of degeneration, focal necrosis and fibrosis. |
