SERUM GLUTAMIC OXALACETIC TRANSAMINASE (SGO-T) DETERMINATIONS IN PROSTATIC SURGERY: REPORT OF CASES J.R.REAGAN,F. W. TAYLOR,R. E. HIGGS, C.B.DAYDEN, E. W. IRVINE, JR. AND E. S. IRVINE
It has been repeatedly demonstrated that elevations most commonly occur in the serum level of glutamic oxalacetic transaminase (SGOT) following damage to the myocardium, liver and skeletal muscle1• Some surgical procedures will elevate the transaminase levels, particularly those involving the liver, lungs and skeletal muscle. 2 Studies have also revealed that in the normal person, surgical procedures will not cause sufficient elevations to mask the characteristic curve caused by a myocardial infarction.a Literature includes relatively few reports of SGO-T determinations in prostatic surgery.a, 4 One of us (J.R.) was faced with the problem of an elevated SGO-T in a patient following transurethral resection. This patient had a negative electrocardiogram and no evidence of liver disease. The current study was then undertaken to determine if this elevation could possibly be a result of the operative procedure.
DISCUSSION
Weisberg and Sampsona reported SGO-T levels in 21 surgical cases, 17 of which were major surgical procedures, and 4 were minor. Included in this report was 1 case of suprapubic prostatectomy. No marked elevation in transaminase TABLE

MATERIALS AND METHODS
Blood samples were drawn on 20 patients, 8, 12, and 24 hours postoperatively (table 1). Transaminase levels were determined by the Reitman and Frankel colorimetric method, 5 and the results were expressed in Karmen units. By this method, the normal range is from O to 40 units, with 40 to 50 considered borderline. 1 Merrill, J.M., Lemley-Stone, J., Grace, J. T., Jr. and Meneely, G.

levels was noted. Elevations were exhibited in 3 patients undergoing major surgery. Only one of these was related to surgery; this case was a thoracotomy. Of the remaining 2 patients, one had a myocardial infarction, and the other, biliary obstruction due to carcinoma of the head of the pancreas. Person and Judge4 reported 7 cases of prostatic surgery, in which the highest elevation recorded

SERUM LEVELS OF SGO-T IN PROSTATIC SURGERY
at the end of 24 hours was 43, certainly not a significant rise. In the current study, 3 cases exhibited borderline elevations of no clinical significance. These elevations were not correlated with any evident pathology. It must be concluded that significant elevations in SGO-T levels, following prostatectomy, cannot be attributed to the operative procedure.
SGO-T levels will remain within normal range following prostatecto1ny. Significant elevations exhibited in postoperative patients are indications of one of the pathologic states known to produce such elevations.
SUMMARY AND CONCLUSIONS
1511 Tenth St., Wichita Falls, Texas (J.R.R., F.W.T., R.E.H.) 1505 Tenth St., Wichita Falls, Texas (E. E.S.I.)
Twenty cases of prostatic surgery are reported, in which no significant postoperative elevation in SGO-T levels occurred. In normal individuals,
