The Relationship between Ultraviolet, Vitamin D and Blood Glucose, in Vivo Study

Asma Bukhari, Faten Khorshid


This study is carried on to investigate the effect of (UV) on the estimate of vitamin D production and the correlation ratio of vitamin D and its impact on the increase of blood glucose finally to prove the relationship via biochemical analysis of Vitamin D and glucose level. 90 adult rats were randomly divided into three groups. G1 (-ve control): This group contains 30 rats that were not exposed to the ultraviolet. Rats were eating daily/4 months. G2 (+ve control): This group contains 30 rats that were not exposed to the ultraviolet. Rats were fasting 2 days and eat the third day frequently (4 months). G3: Test group: To examine the exposed to the ultraviolet for 10 second to simulate sunrise and another 10 second to simulate sunset (using prototype cage). This group contains 30 rats, which were fasting 2 days and eat the third day frequently (4 months). Weights were recorder every week. The blood samples were collected through retro- orbital venous plexus in the zero time, every month, and at the end of four months and the obtained sera were subjected to the Glucose and D3 tests. The results showed that the body weights were reducing significantly in G1 compared with G3 at all measured periods (P < 0.000). Whereas no significant differences between G3 and G2 in all weeks. The Glucose levels in G1 and G3 were raised significantly in (1st, 2nd, 3rd and 4th month) (P< 0 .035), (P< 0 .036), (P< 0.030) and (P< 0.023). Also blood level of Glucose was raised significantly between G3 and G2 in all periods (P< 0 .008), (P< 0 .009), (P< 0.002) and (P< 0.001). Moreover the blood levels of Vitamin D between G1 and G3 were raised significantly in all tested periods (P< 0 .001), (P< 0 .000), (P< 0.000) and (P< 0.003). Also Vitamin D was raised significant (P< 0.000) in G3 compared with G2. This study was proved that vitamin D level was affected by the exposure to ultraviolet that intern affect the glucose level. Also ultraviolet (UV) extend to preservation of glucose homeostasis by raising glucose level. Accordingly ultraviolet (UV) raising vitamin D should be considered since this may help reduce the risk of glucose disorders.
