Changes of glycogen content in liver, skeletal muscle, and heart from fasted rats.

Glycogen content of white and red skeletal muscles, cardiac muscle, and liver was investigated in conditions where changes in plasma levels of non-esterified fatty acids (NEFA) occur. The experiments were performed in fed and 12 and 48 h-fasted rats. The animals were also submitted to swimming for 10 and 30 min.

[Ergospirometry as a method for predicting the clinical course of ischemic, Chagas and idiopathic myocardiopathy].

Purpose: To compare and evaluate the modifications variables obtained through spyroergometry in groups of patients with ischemic cardiomyopathy (IS), Chagas' disease (CH), and idiopathic cardiomyopathy (ID). To study tolerance to anaerobic conditions of patients from the above groups who died.

Methods: A study was carried with 50 male patients, 10 of which were found in normal conditions whereas 40 presented cardiomyopathy with compensated heart failure.
