| Abstract: | The Ca and P concentrations as well as the Ca/P ratio were estimated in intact trabecular bone samples from the femoral neck of healthy humans, 34 women and 44 men, aged from 15 to 55 years, using instrumental neutron activation analysis. The mean values (M+/-SD) for the investigated parameters (on a dry-weight basis) were: 12.1+/-3.0%, 5.94+/-1.71%, 2.07+/-0.25 and 10.9+/-2.5%, 5.30+/-1.23%, 2.07+/-0.22 for females and males, respectively. A statistically significant (p
