[Renal protective effect of nilestriol in aged women with hypertension]

To investigate the renal protective effect of nilestriol in aged hypertensive women.

Forty-one aged hypertensive women treated with antihypertensive drugs were randomly divided into two groups. The women in Group A (n = 21) received nilestriol, whereas those in Group B (n = 20) received a placebo for six months. Antihypertensive drugs were unchanged. Twenty-four healthy subjects were set as the normal control group.

1. Before the treatment, the levels of urinary transferrin (TRF), retinol binding protein (RBP), P-selectin, vWF, and ET-1 were significantly higher in the aged hypertensive women than those in the control group. 2. The levels of TRF and RBP significantly decreased in both Group A and Group B after the 6-month treatment, but these levels in Group A were significantly lower than those in Group B (P < 0.05). 3. The levels of P-selectin, vWF, and ET-1 in Group A were significantly lower than those in Group B (P < 0.05-0.01) after the treatment.

1. In aged hypertensive women treated with antihypertensive drugs, the renal function is still damaged; 2. Nilestriol can significantly decrease the levels of TRF and RBP; 3. The renal protective effect of nilestriol may be related to the protection of endothelin function and antithrombosis activity.
