    Histological And Certain Histochimical Studies on Oviduct of Domestic Hen ( Gallus Domesticus )
    (Birsa Agricultural University, Ranchi, 2002) Suresh Mehta; P.N. Sahay
    In vagina the height of epithelium was maximum. The lamina propriety was very thin in developing birds whereas comparatively thick in laying birds. The mucosal folds were leaf like in developing birds whereas they were slightly wider and finger like in laying birds. The mucosal glands were absent in vagina. The epithelium of vagina in developing birds showed moderate to strong affinity for PAS and bromphenol blue stain and moderate for alcian blue and colloidal iron. On an average lamina epithelial is of laying birds had more affinity for PAS +ve substance and bromphenol blue but had weaker affinity for alcian blue.

    Histomorphological And Certain Histochemical Studies on The larynx And Lungs of Black Bengal Goat ( Carpa Hircus )
    (Birsa Agricultural University, Ranchi, 1998) Mushtak Ahmad Baba; J. Prasad
    Histomorphological and certain histochemical studies were con ducted on the larynx, trachea and lungs of ten adult healthy Black Bengal goats. Histomorphology Larynx: The larynx consisted of mucosa, submucosa, layer of muscles and cartilages and adventitia. The mucosa was composed of non keratinized stratified squamous epithelium upto vocal folds and of pseudostratified columnar ciliated epithelium in the remainder areas. Lamina propria and submucosa were intermingled, containing abundant glands in large groups. The glands were of tubuloalveolar, mucous, seromucous types. Cricoid, thyroid and arytenoid cartilages were hyaline in nature and epiglottis and corniculate cartilages were of elastic type. Laryngeal muscles were of skeletal type and adventitia was composed of loose connective tissue. Trachea: The tracheal wall consisted of mucosa, submucosa, musculo-cartilaginous-layer and adventitia. The tracheal epithelium was of pseudostratified columnar ciliated type with goblet cells. Average thickness of the epithelium was 55.93 ± 2.48 um. Lamina propria and submucosa were blended with each other, containing abundant collagen and clastic fibres, lymphocytes, lymph nodules and blood vessels. Tracheal glands were present in the propria-submucosa. The glands were of tubuloalveolar, mucous or mixed types.

    Comparative Histological and Histochemical Studies on the Liver of Black Bengal Goats ( Carpa Hircus ) and Chotanagpur Sheep
    (Birsa Agricultural University, Ranchi, 1987) Massarat Khan; Dr. J. Prasad
    The liver capsule measured 28.08 in goat and 18.62 in sheep. It was surrounded by a layer of flattened mesothelial cells. It was composed of collagen, elastic and reticular fibras and occasional smooth muscle. The liver capsule indicated intense reactions for bound protein and DMA moderate to weak reactions for PAS positive substances, glycogen, bound lipid, acid mucopolysaccharides and calcium salts in both the species: however reactions for PAS positive carbohydrates and alkaline phosphatase ware of higher intensity in sheep, whereas, a negative reaction was noted for alkaline phosphatase in the liver capsule of goat. Reactions for natural fats, MA, acid phosphatase and ferric iron were found to be absent. Stromal connective tissue contained scanty amount of elastic, collegen fibres and abundant of reticular fibros. The fibroblasts vara comparatively more in the stronal tissues of the sheep. Stromal connective tissus showed intansa reactions for bound protein and DNA moderate to weak reactions for glycogen/ bound lipid, acid mucopolysaccharides and calcium salts in both goat and sheep. The PAS positive carbohydrates and alkaline phosphatase activity in the stromal connective tissus was of higher degree in sheep. Noutral fats, MA, acid phosphatase and forric iron were found to be absent in both the cases.

    Study on the lever of Black Bengal Goats & Chotanagpur Sheep
    (Birsa Agricultural University, Ranchi, 1986) Malay Kumar Roy; Malya Kumar Roy
    Comparative histology and histochemistry of pituitary gland, pineal body, adrenal gland, thyroid gland and Leydig cells of testes were studied in the normal and vasectomized male goats. The normal goats were grouped under prepubertal (3-4 months), circunpubertal (6-7 months) and postpubertal (10-18 months) animals. The prepubertal vasec tomy was done at 3 months of age while postpubertal vasectomy was conducted at the age of 9 months. From vasectomized goats, the tissues were collected after 1, 3 and 9 months of operations. 5.1 PITUITARY GLAND (Glandule pituitaries) The capsule was mainly composed of collagen fibers with a few reticular and elastic fibers. The stroma was rich in reticular fibres. The sinusoidal capillaries were distributed the gland. Histochemically, the capsule and stroma were positive for PAS and acid mucosubstances. The capsule and stroma in the vasectomized goats did not differ from the normal goats. Para distalis adenohypophysis was composed of solid or tubular cell cord. The average cell density per m² area increased with the advancing age of the animals. Statistically the average cell density per m² area in the vasectomized goats did not differ from the corresponding normal values. Both orangeophil and carminophil were identified in the acidophil cells of the goat.

    Comparative Histological and Histochemical Studies on The Liver of black Bengal Goats (capra Hircus ) and Chotanagpuri Sheep (Ovis Aries)
    (Birsa Agricultural University, Ranchi, 1987) Miss Massarat Khan; Dr. J. Prasad
    The liver capsule measured 28.08 u in goat and 产 in sheep. It was surrounded by a layer of flattened 10.62 masothelial cells. It was composed of collagen, elastic and reticular fires and occasional smooth muscle. The liver capsule indicated intense reactions for bound protein and DNA moderate to weak reactions for PAS positive substances, glycogen, bound lipid, acid mucopolysaccharides and calcium salts in both the species? However reactions for PAS positive carbohydrates and alkaline phosphatase ware of higher intensity in sheep, whereas, a negative reaction was noted for alkaline phosphatase in the liver capsule of goat. Reactions for neutral fats, RA, acid phosphatase and ferric iron were found to be absent. Stromal connective tissues contained scanty amount of elastic, collagen tires and abundant of reticular fibers. The fibroblasts were comparatively more in the stromal tissues of the sheep. Stromal connective tissues showed intense reactions for bound protein and DNA moderate to weak reactions for glycogen bound lipid, acid mucopolysaccharides and calcium salts in both goat and sheep. The PAS positive carbohydrates and alkaline phosphatase activity in the stromal connective tissue was of higher degree in sheep. Neutral fats, RIA, acid phosphatase and ferric iron were found to be absent in both the copes.

    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.

    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 pigmentation

    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 goat
