- W72386067 abstract "The present study describes the morphological aspects of the testis and presents a generalcharacterization of the seminiferous elements of adult specimens (N=8) of Allobates femoralis(Boulenger, 1883) collected at the Panguana Biological Station (9°37'S 74°56'W), 250 masl,upstream of the Pachitea river, Yuyapichis district, Puerto Inca province, Huanuco, Peru. Theamphibians (25.99 ± 0.97 mm in length) were dissected and their testes were isolated for macroscopicdescriptions; later, routine histological protocols for microscopic analysis were done, colored withhematoxylin and eosin dye. The germinal stages were described and measured with the help of anocular micrometer. The biometrics of the testes were: major axis = 2.254 mm (SD=0.282), minor axis= 1.343 mm (SD=0.181), width = 0.971 (SD=0.097). At a microscopic level we found the albugineacoat (6.51 ± 1.74 im width) formed by connective tissue and smooth muscle. The seminiferoustubules (162.56 ± 47.61im) were delimited by a thin layer of connective tissue. Regarding themicroscopic features, spermatogenesis in A. femoralis occurs into the seminiferous tubules where thecellular elements are organized in spermatocysts. Each cyst contains cells in the same stage ofdevelopment. The characterization of each cell type allowed the identification of the germ line cells:1) Spermatogonia, isolated cells or forming groups of the most voluminous cells of the germinallinage (7.07 ± 1.187 im) with an irregular nucleus shape. They laid very close to the seminiferoustubule. 2) Spermatocyte I, with a smaller form than spermatogonias (6.95 ± 1.21 im). 3) Spermatids;with a round shape, as they advance in their development, they elongated slightly and are organizedinto bundles whose heads are attached between them. 4) Spermatozoa, elongated with theflagellum lightly stained, are well compacted cells with the nucleus and cytoplasm reduced,elongated and extend into the lumen of the seminiferous tubule. It is reported for the first time themacroscopic and microscopic description of the testis of A. femoralis in Peru." @default.
