[Evaluation of a nutritional intervention to reduce cholesterol levels in patients with coronary artery disease].

Background: The mainstay of cholesterol reduction therapy is the diet. But the lack of compliance and prescription problems limit its usefulness.

Aim: To compare the effectiveness of a nutritional intervention given by a nutritionist with the usual recommendations given by a physician to reduce the LDL cholesterol levels in patients with coronary artery disease, treated at the Regional public hospital in Temuco.

Increased effect of noradrenaline on synaptic responses in rat CA1 hippocampal area after adrenalectomy.

Pyramidal neurons in the rat CA1 hippocampal area contain intracellular receptors for the steroid hormone corticosterone, and membrane associated alpha- and beta-adrenergic receptors. We compared the effect of noradrenaline (NA) on the synaptically evoked CA1 field potential in adrenalectomized (ADX) rats, where corticosteroid receptors are not occupied, with sham-operated controls. It appeared that the increase in the amplitude of the field potential induced by 10 microM NA was more pronounced in slices from ADX rats than in sham operated controls.
