Reduced Liver Lipid Peroxidation in Subcellular Fractions Is Associated with a Hypometabolic State in Rats with Portacaval Anastomosis

Figure 6

Food intake, respiratory quotient, and energy expenditure in rats with PCA. Data were collected over a period of 1-2 days using metabolic cages (PANLAB, Spain). Darker section depicts period with light off. (a) Cumulative food intake, expressed in g, during 24 h. (b) Respiratory quotient (ratio of CO₂ produced by the O₂ consumed) recorded for 2 days. (c) Energy expenditure recorded for 2 days. Data from panels (b) and (c) were recorded every 12 min and the results shown in the graphics correspond to values calculated with the average of every hour. To make simpler the display of the data, only the mean of 6 independent experimental observations are represented; SEM values (corresponding from 8 to 13% of the mean) were omitted. PCA rats showed significant reduction in food intake and respiratory quotient during the dark period and along the 24 h recording in energy expenditure.
