Cholecalciferol rodenticide intoxication in a cat
Journal of the American Veterinary Medical Association, 1991A 4-month-old 2.5-kg sexually intact female domestic shorthair cat was referred to the teaching hospital because of suspected cholecalciferol intoxication after ingestion of a cholecalciferol-containing rodenticide. At referral, the cat was hypercalcemic, hyperkalemic, and acidotic. Despite management of hypercalcemia and preservation of renal function

Fecal Loss of Cholecalciferol in Gastrectomized Rats
Digestion, 1986Rats were gastrectomized, and the intestinal absorption and fecal excretion of cholecalciferol were studied following the administration of radioactive cholecalciferol, either by subcutaneous injection or with the aid of a gastric tube. From measurements of radioactivity in feces and sera it has been possible to establish that gastrectomy in rats ...

The cholecalciferol sulphate system in mammals
Journal of Steroid Biochemistry, 19877-Dehydrocholesterol sulphate has been identified in human and rat skin. The compound was isolated by anion exchange chromatography and following hydrolysis it was characterized by high-performance liquid chromatography and gas chromatography-mass spectrometry.

Cholecalciferol: Properties and Determination
2016Cholecalciferol (vitamin D) is the common form of vitamin D synthesized in animals, and the equivalent form in plants is ergocalciferol (vitamin D). Cholecalciferol is produced from provitamin D in human skin, on exposure to ultraviolet (UV) light. Due to avoidance of sunlight because of skin cancer concerns, vitamin D deficiency has become common in ...

The predominant source of vitamin D is the synthesis of cholecalciferol in the skin by the action of sunlight; however, due to the relative lack of sunlight, the intake of vitamin D from food is emphasized during winter, especially in the northern countries. Only a few foods (fish, eggs, wild mushrooms, meat, and milk) are natural sources of vitamin D.

Cholecalciferol (vitamin D) deficiency rickets remains an occasional problem in poultry. Diagnosis currently relies on analysis of feed and histopathological examination of bone. These experiments were designed to provide data that might allow diagnosis of cholecalciferol deficiency on the basis of plasma concentrations of 25-hydroxycholecalciferol, a ...
