%X Con el prop車sito de comparar la posible relaci車n entre las concentraciones urinarias de boro y las concentraciones de calcio, de magnesio y de f車sforo en suero y orina de mujeres posmenop芍usicas con y sin osteoporosis, seleccionamos 45 mujeres posmenop芍usicas con m芍s de 47 a os de edad, divididas en dos subgrupos: grupo I mujeres posmenop芍usicas cl赤nicamente sanas y grupo II mujeres posmenop芍usicas con osteoporosis, sin enfermedades renales, hep芍ticas o diabetes mellitus. Se determin車 el boro (B), el f車sforo (P), el calcio total (Ca) y el magnesio total (Mg) en la orina de dos horas por espectroscopia de emisi車n at車mica con plasma acoplado por inducci車n (ICPA-ES), el calcio y el magnesio total en suero por espectroscopia de absorci車n at車mica en llama (FAAS) y el f車sforo inorg芍nico en suero y la creatinina en suero y orina por espectroscopia de absorci車n molecular. Los resultados obtenidos sugieren preliminarmente una diferencia significativa (p<0,05) en las concentraciones de boro y de f車sforo en la orina de dos horas entre los grupos estudiados. El an芍lisis de regresi車n lineal aplicado, sugiere relaci車n entre el 赤ndice boro/creatinina y los 赤ndices calcio/creatinina, magnesio/creatinina y f車sforo/creatinina en la orina de las mujeres posmenop芍usicas con osteoporosis. In order to compare the possible relationship between urinary concentrations of boron, calcium, magnesium and phosphorus in serum and urine of postmenopausal women with and without osteoporosis, we selected 45 postmenopausal women over 47 years of age, divided into two groups: group I clinically healthy postmenopausal women and group II postmenopausal women with osteoporosis, without chronic kidney and hepatic diseases or diabetes mellitus. We determined the boron (B), phosphorus (P), total calcium (Ca) and total magnesium (Mg) in the urine of two hours, by atomic emission spectroscopy with induction-coupled plasma (ICPA-ES). Total calcium and total magnesium in serum were determined by atomic flame absorption spectroscopy (FAAS) and inorganic phosphorus in serum, and creatinine in serum and urine, by molecular absorption spectrometry. The preliminary results suggest the existence of a significant difference (p <0.05) in boron and phosphorus concentrations in the urine of two hours between the groups. The model of linear regression analysis used showed a relationship between urinary concentrations of boron/creatinine index and calcium/ creatinine, magnesium/creatinine and phosphorus/creatinine indexes in the urine of postmenopausal women with osteoporosis.
