Figure 4. Passive distensibility of mesenteric arteries from female (A) and male (B) rats at 3 months and female (C) and male (D) rats as 6 months fed either a high or low isoflavone diet.

At 6 months female rats fed the high isoflavone diet showed increased arterial distensibility compared with female rats fed the low isoflavone diet (*P < 0.05 high isoflavone versus low isoflavone fed rats). Data are presented as the mean ±s.e.m.
