NICKEL IMPROVES IRON ABSORPTION

Cempel M. (2004). Effect of nickel(II) chloride on iron content in rat organs after oral administration. Biol Trace Elem Res. 102(1-3):189-98.

The effect of oral administration of nickel(II) chloride on iron content in serum and certain body organs of rats was investigated. The male adult rats were given 300 and 1200 ppm Ni in drinking water for 90 d. The iron content in serum, liver, kidney, lung, spleen, and brain was analyzed 30 and 90 d postexposure. The hemoglobin, hematocrit, and body and organ weights were also measured. Nickel given in drinking water led to a pronounced increase in iron content in serum and the liver, as compared to control rats. This effect was related to Ni concentration in the water. There was not great time-dependent difference in the iron content as a response to continuous nickel treatment, except the lung of 1200-ppm Ni-treated rats. In relation to hematological parameters, Ni supplementation did not affect any of them. Body weight significantly decreased, and lung weight was significantly increased in 1200-ppm Ni-treated rats. The results of this study indicate that nickel ingestion (300 and 1200 ppm in the drinking water) induces the iron uptake by serum and some organs of rats. The highest amount of iron was found in the liver of all exposed animals, and the time-dependent difference in iron content was observed in the lung of 1200-ppm Ni-treated rats.
