Abstract:
For the purposes of the adrenal gland’s study, 27 four months old male rabbits (Oryctolagus cuniculus) of Termond White breed were selected. Based on electrocardiography and variation pulsometry results, three types of autonomous tonus were determined in animals: sympathicotonia (ST), normotonia (NT) and parasympathicotonia (PS), which formed the basis for the division of animals into three groups. All rabbits were subjected to euthanasia and histological preparations were made from their adrenal glands. Apart from the main adrenal gland, accessory adrenal gland was detected in five purposes a

Abstract:
All mammalian uteri contain glands that synthesize or transport and secrete substances into the uterine lumen. Uterine gland development, or adenogenesis, is uniquely a postnatal event in sheep and pigs and involves differentiation of glandular epithelium from luminal epithelium, followed by invagination and coiling morphogenesis throughout the stroma. Intrinsic transcription factors and extrinsic factors from the ovary and pituitary as well as the mammary gland (lactocrine) regulate uterine adenogenesis. Recurrent pregnancy loss is observed in the ovine uterine gland knockout sheep, providing

Introduction Adrenal insufficiency is a typical complication after surgical treatment of adrenal tumors, especially after the removal of both adrenal glands. Human beings are not able to survive without adrenal glands and without proper hormonal substitution. Autotransplantation of a fragment of the adrenal gland may prevent this complication. This can be done by transplanting the entire adrenal glands or its fragment, such as the adrenal cortex cells. In the case of adrenal tumors, the entire adrenal gland can not be transplanted.

Several reptiles possess glands capable of secreting fluids with sodium chloride as the major solute.

Abstract:
Abstract The accessory reproductive glands of male mammals contribute the bulk of the secretions in which spermatozoa are transported to the female tract during copulation. Despite their morphological diversity, and the chemical complexity of their products, little is known about the possible effects of sexual selection upon these glands in mammals. Here we consider the seminal vesicles and prostate glands in a sample of 89 species and 60 genera representing 8 Orders of mammals. The sizes of the accessory glands are analysed in relation to body weight and testes weight. Both the seminal vesicl

The implication of STAT5A and STAT5B in mammary gland development and maintenance of lactation is well documented in rodents and humans. However, little is known regarding their roles in mammary gland development during gestation in pigs. We identified and analyzed the complete coding sequences of swine STAT5A and STAT5B and evaluated their mRNA levels in mammary glands of gestating gilts (day 110) in two different breeds, Upton-Meishan and Large White. Sequence analysis revealed a new APASA insertion in the STAT5A amino acid sequence that is in close proximity to residue Tyr 699 and whose pho

This tube, which enters the gland at its rostrolateral extremity and runs caudodorsally, is partially filled with stiff hairs that arise from follicles in its wall.

Post-irradiation replacement of salivary gland stem cells with donor stem cells may ameliorate radiation-induced complications.
