ThesisItem Open Access Histological and Histochemical studies on the testes and accessory sex glands of Normal and vasectomies Goats(Birsa Agricultural University, 1983) Pyne, Saroj Kumar; Sinha, R.D.Histological and histochemical studies were made on testes along with epididymis, seminal vesicles, prostate (Pars-disseminata) and bulbo-urethral glands of normal and vasectomised Black Bengal goats. Animals were divided into 3 groups: 3 months after vasectomy (Group I); 6 months after vasectomy (Group II) and 12 months and above after vasectomy (Group III). Each group consisted of 3 vasectomised and 3 normal goats. Testes: The testes enveloped by a capsule comprised of inner tunica albuginea and outer tunica vaginalis. The interstitial cells were present at the inter tubular region. The testicular parenchyma consisted of seminiferous tubules. The spermatogenic cells were present in several layers and Sertoli cells were placed basally in between the spermatogonia. Mature sperms lied over indistinct Sertoli cells. After 3 months of vasectomy, diameter of the seminiferous tubules were reduced significantly (P 0.01). Spermatogenesis was increased as evidenced by the significant increase of the thickness of stratified epithelium. Some Leydig cells showed hypertrophy and hyperplasia. After 6 months of vasectomy, spermatogenesis was increased highly but a few tubules showed desquamation of primary spermatocytes and spermatids into the lumen.ThesisItem Open Access Histological and Histochemical studies on the skin of the Indian buffalo and the goat(Birsa Agricultural University, 1984) Gayan, Sukumar; Prasad, C.Histological and histochemical studies were conducted on akin of the buffaloes, (age-1 yr.,l yr.,1.25 yrs., 1.5 yrs., 1.5 yrs.. 4.5 yrs.) and six Black Bengal goats (age- 1 yr., 1 yr., 1.25 yrs., 2 yrs., 2 yrs., 2 yrs.). GENERAL FEATURES Thickness of the skin: The present investigation of the skin of Indian buffaloes (adult) revealed an average total skin thickness of 5.93 mm. ranging from 4.03 mm. on medial aspect of lower forelimb to 7.83 mm, on the ventral neck. In Black Bengal goats, average total skin thickness was of 2.36 mm. ranging from 1.6 mm. on medial aspect of lower forelimb to 3.02 mm. on the ventral neck. In both species, the skin was thicker on the dorsal body region, lateral region of the limbs and ventral neck. Epidermal thickness: Thickness of the epidermis was grouped into papillomata’s epidermis and the main epidermis. In Buffalo, the average thickness of papillomatous epidermis and main epidermis was 149.53 um. and 62.137 um respectively. The thickness of main epidermis was more or less similar in all body regions. In goats, the average thickness of main epidermis and papillomatus epidermis were 32.7 um. and 88.64 um. respectively. It appeared that in goats, the thickness of the epidermis was lesser due to thinner skin, whereas buffaloes had thicker epidermis in thicker skin. However, in case of individual species, thick epidermis was not necessarily evident in the thicker skin pigmentationThesisItem Open Access Comparative Histological and histochemical studies on the lips and planum nasolabiale of Indian Buffalo (Bubalus Bubalis) ox (Bas Taurus) and goat (Capra hircus)(Birsa Agricultural University, Ranchi, 1985) Sinha, Sajay Kumar; Prasad, J.The skin of PNL/PH and upper and lower lips was thickest in buffalo, thicker in ox and thinnest in goat. Epidermis of PNL of ox was the thickest. It was thicker in buffalo and thinnest in goat. Mucosal epithelium of PNL/PN and both lips was thickest in ox, thicker in buffalo and thinnest in goat. The skin of PML/PH was thickest as compared to the skin of the other parts of the lips. However, the skin of the lower lip was thicker than the upper lip and the mucous membrane of upper lip was thicker than the mucous membrane of the lower lip in all the species under investigation. The general skin of upper and lower lips was less pigmented than PNL. The lips and PNL of buffalo were more pigmented than that of ox and goat. The nuclei of the cells of stratum corneum were indistinct in the skin of PNL of buffalo, however they were distinctly marked in the upper and lower lips. The stratum corneum in ox and goat did not show the presence of nuclei, Stratum lucidum was found to be absent in all the species under investigation. Stratum grnulosum was 2-3 cell layer thick in buffalo and ox and 1-2 cell layer in goat. This layer was found to be absent in the muzzle skin of buffalo and ox. The cells of stratum spinosum of the skin of lips and PL. in all the three groups of animals were mostly polygonal but in goat superficial cells were rhomboidal and parallel to the surface. stratum cylindricum contained melanocytes which were more in buffalo and goatThesisItem Open Access Comparative histological and histochemical studies on the eyelids of goat (Capra Hircus) and sheep (Ovis Aries)(Birsa Agricultural University, Ranchi, 1987) Baba, Mushtak Ahmed; Sinha, R. D.Comparative histological and histochemical studies were conducted on the upper, lower and third eyelid (nictitating apparatus) of goat and sheep. Twelve healthy Black Bengal goats and an equal number of Chotanagpuri sheep between 1-2 years of age were utilized for the investigation. HISTOLOGY SYELIDS (PALPEBRAS):Histologically, the eyelids in goat and sheep consisted of skin, subcutis, muscular layer, tarsus, tarsal glands and palpebral conjunctiva. The skin comprised of epidermis, dermis with dermal elements hairs and hair follicles, sweat and sebaceous glands. Average thickness of epidermis in goat (41.01± 1.67 ) was significantly higher than that of sheep (28.70 ± 1.24 μ). It was composed of keratinized stratified squamous epithebium having rate pags towards the free lid margin. Rete pags ware more prominent in goat. Stratum lucidum was absent in both. Epidermis was pigmented mainly towards the free edge of the lid. Pigmentation was more intense in goat than in sheep. Dermis was composed of collagen, reticular and elastic fibres and was divisible into superficial (papillary) and deep (reticular) layers. In goat, collagen fibres in the papillary layer were mostly arranged parallel to surface, whereas in sheep, these were arranged irregularly.ThesisItem Open Access Comparative histological and histochemical studies on the pancreas of black Bengal goats (Capra Hircus) and Chotanagpuri Sheep (Ovis Aries)(Birsa Agricultural University, Ranchi, 1987) Lone, Zahseen Kausar; Prasad, G.Under the present investigation a comparison was made between the histological and certain histochanical picture of the pancreas of goat and sheep. Irrespective of Sex, pancreatic tissues of twelve adult animals from each species formed the basis of this investigation. The following conclusions ware dram: The goat pancreas had more typical ruminant characteristics as compared to sheep. Goat pancreas had loose architecture with the acini, islets and ducts loosely placed within the storm. Sheep pancreas was compact and rim with denser connective tissue elements. Pancreatic capsule in goat was moderately thick (116-15 am) with appreciable capsula-adiposa and diffused sub-capsular fat. sheep pancreas had comparatively thicker capsule (123.75 m). Lymphatic aggregations, blood vessels and nerve bundles were present in the capsule. Smooth muscle bundles ware found only in sheep capsule. Interlobular stroma had predominant collagen, lesser reticular and few elastic fibrous. In goat, the stroma had loose architecture as compared to sheep, where it was compact. Sheep had denser concentrations of connective tissue in the saptae as compared to goat. Interlobular adipose tissue was present. Large areas comprising of blood vessel and herves were found in the saptations. Ganglionic calls ware present in the septa.ThesisItem Open Access Comparative histological and histochemical studies on the lips and planum nasolabiale of Indian Buffalo(Bubalus Bubalis) ox (Bos Taurus) andgoat (Capra Hircus)(Birsa Agricultural University, Ranchi, 1985) Sinha, Sanjay Kumar; Prasad, J.The skin of PML/PH and upper and lower lips was thickest in buffalo, thicker in ox and thinnest in goat. Epidermis of PNL of ox was the thickest. It was thicker in buffalo and thinnest in goat. Mucosal epithelium of PNL/PN and both lips was thickest in ox, thicker in buffalo and thinnest in goat. The skin of PNL/PN was thickest as compared to the skin of the other parts of the lips. However, the skin of the lower lip was thicker than the upper lip and the mucous membrane of upper 11p was thicker than the mucous membrane of the lower lip in all the species under investigation. The general skin of upper and lower lips was less pigmented than PNL. The lips and PNL of buffalo were more pigmented than that of ox and goat. The nuclei of the cells of stratum corneum were indistinct in the skin of PNL of buffalo, however they were distinctly marked in the upper and lower lips. The stratum corneum in ox and goat did not show the presence of nuclei, Stratum lucidum was found to be absent in all the species under investigation. grnulosun was 2-3 cell layer thick in buffalo and ox and 1-2 cell layer in goat. This layer was found to be absent in the muzzle skin of buffalo and ox. The cells of stratum spinosum of the skin of lips and PNL in all the three groups of animals were mostly polygonal but in goat superficial cells were rhomboidal and parallel to the surface. stratum cylindricum contained melanocytes which were more in buffalo and goat than ox.ThesisItem Open Access Histological and histochemical studies on lactating and nonlactating mammary glands of black bangal and jamunapari cross reed goats(Birsa Agricultural University, Ranchi, 1983) parmar, Mangi lal; Sinha, R.D.Histological and histochemical studies were conducted on thirty six mammary glands of lactating and nonlactating Black Bengal and Jamunapari cross-bred goats, HISTOLOGY Udder skin The thickness of the epidermis and dermis of the udder skin was greater in high milk-yielder Jamunapari cross-bred goats than in low milk-yielder Black Bengal goats. It was probably due to greater pressure caused by more milk accumulation in the Jamunapari cross-bred goats. Capsule and supporting tissue- The external lamina of the capsule was comprised mainly of collagenous and elastic fibers. Reticular and smooth muslce fibers were occasional in distribution. The medial suspensory ligament was rich in elastic fibers. Remarkable differences in the histomorphology of the capsule between lactating and nonlactating Black Bengal and Jamunapari cross-bred goats were not noticeable. The interlobular stroma was comprised of collagenous and fine elastic fibers. Adipose tissue was occasionally seen. The connective tissue stroma was more in lactating Black Bengal than in Jamunapari cross-bred goats. In nonlactating goats of both breeds, the interlobular connective tissue stroma was greater in amount than the glandular tissue. The intralobular stroma was highly cellular in lactating as well as in nonlactating goats of both the breeds.ThesisItem Open Access Comparative Histological and Histochemical studies on thr eyelids of goat (Sapra Hircus) and Sheep (Ovis Aries)(Birsa Agricultural University, Ranchi, 1987) Baba, Mushtak Ahmed; Sinha, R. D.Sepithelium of nictitating membrane manifested positive reactions for glycogen, alkaline phosphate, 1ipids, proteins and acid mucopolysaccharides in both the species. Basement membrane exhibited mild PAS-positive reaction. Cartilage showed positive reaction for acid mucopolysa chariden, glycogen, lipids and carbohydrates. Nictitating gland manifested positive reactions for glycogen, lipids, protein, alkaline phosphatase and acid mucopolysaccharidas.ThesisItem Open Access Comparative histological and histochemical studies on the pancreas of black Bengal goats capra hircus andchotanagpuri sheep ovis aries(Birsa Agricultural University, Ranchi, 1987) lone, Lahseen Kausar; Prasad, G.Under the present investigation a comparison was made between the histological and certain histochemical picture of the pancreas of goat and cheap.
