Toxicity of organotin compounds in chicken and rats. 1980

Di-methyltin-dichloride (DMTC), di-butyltin-dichloride (DBTC), di-octyltin-dichloride (DOTC) and two commercial products (CP 1, CP 2) used as stabilizers in plastics induce a dose-related decrease of the thymus weight in young rats when given by gastric intubation for 10 or 14 days; in the chicken a decrease of the bursa Fabricii weight can also be observed. It is of interest, that there are distinct differences in response between the animal species. The sensitivity in acute toxicity tests does not correspond with the sensitivity of thymus and bursa Fabricii. The response is also dependent on the vehicle in which the agent is given.

D002060 Bursa of Fabricius An epithelial outgrowth of the cloaca in birds similar to the thymus in mammals. It atrophies within 6 months after birth and remains as a fibrous remnant in adult birds. It is composed of lymphoid tissue and prior to involution, is the site of B-lymphocyte maturation. Fabricius Bursa
D002645 Chickens Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA. Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken

Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D013950 Thymus Gland A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
