1. Aspects of Vitamin D : Prevalence of deficiency and impact on musculoskeletal parameters
Sammanfattning : Vitamin D is central in calcium turnover, and adequate levels are important for skeletal health. It is not clear how large contributions from food and sunlight are in Swedish primary care patients, considering the low radiation of UVB in Sweden and fortification of some foods, and whether differences exist between patients of immigrant and Swedish origin.

2. Vitamin A and Osteoporosis : Experimental and Clinical Studies
Sammanfattning : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. LÄS MER
3. Vitamin D Hydroxylating Enzymes and Analogues in Parathyroid Tumors and Breast Cancer
Sammanfattning : In hyperparathyroidism (HPT) raised serum concentrations of ionized calcium is caused by increased secretion of parathyroid hormone (PTH) by parathyroid tumors. Active vitamin D, 1α,25-dihydroxyvitamin D3, is known to suppress PTH secretion and to reduce proliferation of parathyroid tumor cells. LÄS MER

5. Vitamin D and its role in obesity and other associated conditions
Sammanfattning : Vitamin D has received much attention in recent years due to the re-emergence of vitamin D deficiency as a global health issue along with increasing evidence indicating that 1,25-dihydroxivitamin D, the hormonally active form of vita-min D, not only acts in calcium and bone metabolism but also generates ex-traskeletal biological responses.In this thesis, the role of vitamin D in obesity and other associated condi-tions has been studied.
