Elevated 1-α Hydroxylase Activity in Monocytes from Patients with Active Tuberculosis
Figure 2
Quantitation of 1,25(OH)2D3 in patients with active TB and frequent TB contacts. RIA measurement of 1,25(OH)2D3 purified from monocyte suspensions cultured with 25(OH)D3 for 3 hours. The amount of 1,25(OH)2D3 in the active TB group was significantly higher than that in the frequent TB contact group. Each column represents the mean of 1,25(OH)2D3 quantitation. Error bars represent the standard deviation. *.
