    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 Histochemical Studies on Certain Sex-Related Endocrines of Normal and Vasectomized Male Goats
    (Birsa Agricultural University, Ranchi, 1987) Malay Kumar Roy; Dr. R.D. Sinha
    Comparative histology and histochemistry of pitui tary 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), circumpubertal (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.

    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.
