A comparable group of rats fed on basic diet only was used as a control.Results obtained indicate that all the measured parameters (serum calcium and phosphorus level, femur weight and its calcium and phesphorus content, and the osteometry of the tibia) showed no significant difference between the experimental and the control groups.Thus there is no adverse effect either on the calcium and phosphorus metabolism or on the bone after a long-term intake at a moderate dosage.展开更多

It not only exhibits a major physiological function to regulate the metabolism of calcium and phosphorus, but also relates to the prevention and treatment of a variety of diseases such as lung diseases, cancers, diabetes, tuberculosis, lupus erythematosus, autoimmune diseases and liver damage. In this paper, the latest research progresses of the physiological function of vitamin D were summarized and discussed, aiming at providing the solid basis for utilization and application of vitamin D.展开更多
