Is attenuation of experimental hypertension by dietary linoleic acid model dependent?
Safflower oil has a hypotensive effect only in the two-kidney, one-clip rat on a low NaCl, but not on a high NaCl intake, and not in Dahl-S rats. Additional studies are required to identify the mechanism(s) for the hypotensive effect of safflower oil and to define the relationship of this animal study to human hypertension.
Our results indicate that serpentine soils do not constitute an extreme environment for ectomycorrhizal fungi, and raise important questions about the role of symbioses in edaphic tolerance and the maintenance of biodiversity.
