title: Effect of homocysteine on bone mineral density of rats.
abstract: The relationship between plasma levels of homocysteine (Hcy) and femur bone mineral density (BMD) was studied in Wistar rats. After 8 weeks of treatment with 0.5 and 1.0 g kg(-1) day(-1) l-methionine the mean plasma levels of Hcy were 7.67 +/- 1.25 and 61.2 +/- 11.4 micromol/l, respectively. Only rats treated with the higher dose had Hcy levels significantly higher than those of controls, 6.38 +/- 0.90 micromol/l (p < 0.001). Dual Energy X-ray Absorptiometry was used to measure the BMD, which was significantly lower only in the animals with the highest plasma levels of Hcy (p < 0.001). This led us to conclude that increased levels of Hcy are associated with risk of decreased BMD.
