Abstract | BACKGROUND/AIMS: Activation of reticuloendothelial system functions by the treatment with OK-432 has been reported to enhance liver regeneration. However, its effect on liver regeneration has not been studied after hepatectomy under ischemia/reperfusion which is in clinical use. The aim was to examine the effect of OK-432 on regeneration and energy status of the liver after hepatectomy under ischemia/reperfusion in rats. METHODOLOGY: Rats were randomly divided into two groups; OK-432 pretreatment and saline treatment (control) group. In the OK-432 group, OK-432 (2.5 mg/kg body weight) was administered intraperitoneally 24 hours before hepatectomy. In the control group, the same volume of physiological saline was administered in the same manner. Seventy percent hepatectomy was performed in both groups during the second 15-minute ischemia period after an initial 15-minute ischemia and 15-minute reperfusion periods. The survival after hepatectomy, relative liver weight, deoxyribonucleic acid synthesis rate, and hepatic adenine nucleotide and energy charge levels were examined immediately after hepatectomy and on postoperative days 1, 2, 3, and 7. Serum levels of total bilirubin, glutamic pyruvic transaminase, and hyaluronic acid were also measured. RESULTS: CONCLUSIONS: Under ischemia/reperfusion, pretreatment with OK-432 has no significant effect on regeneration and energy status of the liver after hepatectomy.
