It was found that the eye in P. stoliczkanus comprised three layers—external, middle uveal and inner. The external layer consisted of the cornea and sclera. The cornea showed three layers: 1) corneal epithelium, 2) corneal stroma and 3) corneal endothelium, while the sclera exhibited a thick connective fi ber and an external sheath of hyaline cartilage supporting the sclera. The middle uveal layer showed only the lens and choroid. The lens protruded into the aqueous chamber. The choroid was subdivided into two distinct layers: 1) a connective layer adjacent to the sclera and 2) the lamina vasculosa and choriocapillaris. The inner layer or retinal tunica was composed of 10 distinct layers: 1) pigment epithelium, 2) photoreceptor layer, 3) outer liming membrane, 4) outer nuclear layer, 5) outer plexiform layer, 6) inner nuclear layer, 7) inner plexiform layer, 8) ganglion cell layer, 9) optic nerve layer and 10) inner limiting membrane, respectively, from the outside inward. These results provided data for other investigations in aquaculture, reproductive biology and histopathology. Keywords: eye, histology, Puntius stoliczkanus, Tapee river, Thailand |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Histological Study of the Intestine of Stoliczkae's Barb Puntius stoliczkanus (Day, 1871) (Cypriniformes: Cyprinidae)) ผู้เขียน:Sinlapachai Senarat, Watiporn Yenchum, พิสิษฐ์ พูลประเสริฐ สื่อสิ่งพิมพ์:pdf AbstractThe histological and histochemical characteristics of the digestive tract of Stoliczkae's barb Puntius stoliczkanus (Day, 1871) were examined. This fish had an intermediate gut length with the nonexistence of the stomach. The histology revealed that the intestine consisted of four different layers: mucosa, submucosa, muscularis and serosa. The mucosa comprised the various villi and simple, columnar epithelia which were lying on the lamina propria. Muscularis mucosae and mucosal tubular glands were not present. Eosinophilic granular cells were observed along the intestine, mainly beneath the lamina propria. Histochemical analysis showed the goblet cells and eosinophilic granular cells react positively with periodic acid-Schiff. This research reports on the histological study of the alimentary tract of P. stoliczkanus for the first time. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Eye Structure and Chemical Details of the Retinal Layer of Juvenile Queen Danio Devario regina (Fowler, 1934)) ผู้เขียน:Piyakorn Boonyoung, Sinlapachai Senarat, Jes Kettratad, พิสิษฐ์ พูลประเสริฐ, Watiporn Yenchum, Wannee Jiraungkoorskul สื่อสิ่งพิมพ์:pdf AbstractThe eye structures and chemical details of the retinal layer in juvenile Queen Danio—Devario regina, an ornamental fish—were histologically investigated under a light microscope. Sample fish were collected from the Tapee River, Nakhon Si Thammarat province, Thailand and their heads were exclusively prepared using a standard histological technique. The results revealed that the eye of D. regina was composed of three layers—inner, middle and external—based on histological organization and cell types. The inner layer was composed of 10 layers; 1) pigment epithelium, 2) photoreceptor layer, 3) outer liming membrane, 4) outer nuclear layer, 5) outer plexiform layer, 6) inner nuclear layer, 7) inner plexiform layer, 8) ganglion cell layer, 9) optic nerve layer and 10) inner limiting membrane, respectively. The localization and chemical details showed that a periodic acid-Schiff reaction for the detection of glycoprotein was intensive in the pigment epithelial layer whereas the inner plexifrom layer had only a slight reaction. Reaction of aniline blue was employed for the detection of mucopolysaccharide which was slightly positive for three layers—the outer limiting membrane, outer plexiform and inner plexiform. |
