Previously we reported carbon tetrachloride-induced body weight loss in rats as a new model of wasting disorders. The oral administration of a low dose of carbon tetrachloride to rats reduced the body weight and food intake at 24 h with a minimal effect on plasma alanine aminotransferase activity. Tumor necrosis factor-alpha, and cyclooxygenase-1 and -2 mRNA expression in the brain was not affected by carbon tetrachloride. Zaltoprofen, which is a non-steroidal anti-inflammatory drug, prevented the carbon tetrachloride-induced body weight decrease, without preventing the carbon tetrachloride-induced loss of food intake. The present results suggest the possible application of this drug for the treatment of wasting disorders.
