Peritonitis in rats was produced by cecal ligation and puncture. Sixteen hours following cecal ligation and puncture, the gangrenous cecum was removed and the animals received either 4 ml saline (nontreated), 0.75 ATP-MgCl2 (100 mumoles ATP plus 50 mumoles MgCl2), and 2.0 ml of 50% glucose or 2.0 ml of 50% mannitol and 1.25 ml saline. Two hours after the removal of the cecum, RES function was evaluated by measuring the intravascular clearance of a 131 I triolein-labeled gelatinized test lipid emulsion. The intravascular half-time (t1/2) in the nontreated animals was double that of sham-operated animals, suggesting that significant depression in RES function occurred during sepsis. Administration of ATP-MgCl2 plus glucose following sepsis resulted in t1/2 values similar to those of sham-operated animals, indicating that the impairment of pagocytic activity of the RES was reversed with treatment. The beneficial effect of treatment following sepsis does not appear to be due to hypertonicity, since administration of 50% mannitol failed to decrease the t1/2. The precise mechanism of the beneficial effect of ATP-MgCl2 + glucose on restoration of RES function is not known.

Our previous studies have claimed that cirrhotic rats, induced with CCl4, showed depressed reticuloendothelial system (RES) function and increased susceptibility to infection. We have also shown that OK-432, a non-specific immunopotentiator, and ATP-MgCl2, which improves depressed intracellular energy metabolism, improve RES function of cirrhotic rats and that thereby improve survival following peritonitis or hepatectomy. The present study was undertaken to investigate whether OK-432 or ATP-MgCl2 could be beneficial for the prevention of multiple organ failure (MOF) following hepatectomy among the cirrhotics. The cirrhotics with hepatocellular carcinoma, who underwent partial hepatectomy (segmentectomy or subsegmentectomy) were given OK-432 (5 KE/day for 4 days) preoperatively or ATP-MgCl2 (50 mumole/kg) within 24 hours following the operation. The rates of postoperative pulmonary complication and the operative mortality were compared among OK-432 group, ATP-MgCl2 group and controls. The rates of posthepatectomy pulmonary complication and operative mortality were decreased with these treatments compared to the controls. The RES function was also improved with these treatments. These data suggest that the cirrhotic patients are the immunocompromised hosts showing the depressed RES function and that the enhancement of RES function with OK-432 or ATP-MgCl2 is beneficial for the prevention of posthepatectomy MOF among cirrhotics.

Studies in rats with a clinically relevant form of peritonitis indicate that tissue adenine nucleotide levels do not decrease in the early stages of sepsis. In contrast, hepatocellular active transport appears to be depressed even in the very early stages of sepsis. In late sepsis, however, tissue adenine nucleotide levels decrease significantly because of inadequate perfusion associated with peritonitis. Reticuloendothelial function (RES) is also significantly depressed at the late stages of sepsis. Administration of saline, glucose, or ATP-MgCl2 alone following sepsis does not produce any beneficial effects on survival. However, administration of high concentrations of ATP-MgCl2 together with hypertonic glucose results in a significant improvement in the survival of animals. This treatment regimen restores cellular ATP levels and also restores the depressed RES function to normal within three hours. Thus, extirpation of the lesion producing the septic process, combined with metabolic support, proves helpful without antibiotic treatment.

Oxygen metabolites formed during reperfusion of ischemic kidneys prevent recovery of renal function after short periods of renal ischemia. The administration of ATP-MgCl2 is beneficial to the survival of animals after hemorrhagic shock, severe burns, septicemia-peritonitis, post-ischemic hepatic failure, bowel ischemia, and endotoxic shock. In this study, the effect of ATP-MgCl2 on lipid peroxidation and its curative effect were evaluated by measuring the decomposition products of lipid peroxidation, detected as thiobarbituric-acid reactive substances in homogenized kidney tissues in ischemic and reperfused rabbit kidneys. Ischemia was performed by clamping the right renal artery for 60 minutes followed by 30 minutes of reperfusion. Thirty-six rabbits were classified into 6 groups containing 6 rabbits in each. In the first group, no renal ischemia-reperfusion (I-R) was designed (Sham group), the right kidney was removed 90 minutes later. In the second group, I-R was established but nothing given. Saline 0.25 cc/kg was given into the right renal artery in group 3 two minutes before ischemia, and in group 4 two minutes before reperfusion. ATP-MgCl2 17.5 mumol/kg (0.25 cc/kg) was given two minutes before ischemia in group 5, and before reperfusion in group 6. The right kidneys of the rabbits were removed and thiobarbituric-acid reactive substances in the homogenates were measured. In addition, histopathological evaluation was performed. High lipid peroxidation products were recorded in groups 2-5, whereas in group 6, these levels were low similar to those obtained in Sham group (76.72 +/- 1.01 nmol/g tissue). On histopathological evaluation, a considerable cell damage resulting from I-R trauma especially in proximal tubules was observed. In groups which were under saline effect, no histopathological damage was found. Histophatological preservation was better in group 6 rather than in group 5. The results of this study indicate that ATP-MgCl2 is remarkably effective for preventing the lipid peroxidation if given before reperfusion but not before ischemia in experimental I-R injury in rabbit kidneys.
