Attenuated metabolic response to surgery in tumor-bearing rats.
Effects of epinephrine on urea synthesis in vivo in rats.
Epinephrine in physiological concentrations cannot by itself account for the increase of urea synthesis seen in vivo after surgery, suggesting that catecholamines might be of regulatory importance.
Blockade of glucocorticoid receptors prevents the increase in urea synthesis after hysterectomy in rats
Abstract. The postoperative increase in hepatic conversion of amino nitrogen to urea nitrogen seems to be a primary cause of post‐surgical catabolism. The importance of glucocorticosteroids for the


Increased hepatic amino nitrogen conversion after elective cholecystectomy in man.
1. The effect of elective, uncomplicated cholecystectomy on plasma clearances of amino acids and on amino acid-stimulated urea synthesis was investigated in 10 patients, pre-operatively and on the
The exchange of blood-borne amino acids in the leg during abdominal surgical trauma: effects of glucose infusion.
A high release of amino acids at the end of surgery was thus associated with low arterial levels of 3-hydroxybutyrate while the reverse pattern was seen in the control patients.
Muscle protein metabolism of rats in surgical trauma.
The effects of decreased food intake and degree of surgical trauma on total, myofibrillar and sarcoplasmic muscle protein synthesis and degradation were assessed in two experiments and trauma depressed total protein content of muscle.
Postsurgical muscle protein turnover in perfused hindquarters of the rat.
The effect of trauma on protein turnover appears not to be due to decreased nutrient consumption, and the role of decreased postoperative nutrient intake on muscle protein turnover is explored.

The reductions in cardiac output and heart blood flow indicate that the heart also made a contribution to energy conservation in the effects of starvation.
Distribution of an ammonia load in the normal rat.
It was observed that the muscle is highly efficient in removing ammonia from the circulation; the metabolite apparently is actively retained in this tissue.
Progressive hepatic arterial flow increase after end-to-side portacaval shunt in normal and cirrhotic rats.
In rats in which cirrhosis was induced by CCl4, the HBF is decreased and the contribution of the hepatic artery raised, and after portacaval shunting, the increase of the HABF, although less pronounced, is also progressive and takes 4 h to reach its maximum.
The effects of arterialisation of the portal stump on liver function and hepatic haemodynamics in cirrhotic rats with a portacaval shunt.
The results suggest that arterialisation of the portal vein with an artery which does not significantly increase sinusoidal pressure may be of benefit in preventing the early undersirable sequelae of PCS in man.
Protein degradation in muscle: response to feeding and fasting in growing rats.
The results support the presence of a diurnal pattern of protein degradation as well as increased muscle degradation during starvation, and the fractional degradative rate.
