Results of this study suggest that Hcy, folate or vitamin B(12) levels were not related to BMD in population of healthy Croatian women aged 45-65. In the group of postmenopausal Croatian women, beside BMI and age, alcohol consumption was significant positive predictor of BMD at the lumbar spine.

Synthesis and Structure of Dehydro-4-iminoallantoin and its CovalentAdducts.-In contrast to earlier reports, the oxidation of the uric acid (I) by ferric cyanide in aqueous NH3 results in the formation of (III) and ( IV). Subsequent treatment of (III) with AcOH yields the dehydroallantoin (V) which forms covalent adducts like (VIII). Oxidation of methylated uric acids afford only products of the type ( IV). -(POPOVIC, T.; SOKOLIC, L.; MODRIC, N.; PALKOVIC, A.; POJE, M.; Tetrahedron 47 (1991) 2, 317-322; Lab. Org.
