Muscles from three patients were obtained during continuous ischemic periods and were investigated ultrastructural changes to know the reversible tourniquet time. Tourniquet was applied for periods lasting between 60 minutes and 90 minutes in the human and muscle biopsies were taken from 10 minutes to 90 minutes ischemic period and at the same periods after release of the tourniquet. All specimens were investigated with electron microscopy and the results were as follows: In 10 minutes tourniquet period, loss of cristae in few mitochondria were observed. In 30 minutes tourniquet period, partial swelling, loss of cristae and myelin figure in many mitochondrias and vacuolar dilatation in T-tubule and sarcoplasmic reticulumn were observed. In 60 minutes tourniquet period, above change were observed in nearly all mitochondrias and total number of mitochondrias were decreased. In 90 minutes tourniquet period, above changes were more distinct. 20 minutes after release of 90 minutes tourniquet period, small sized new mitochondria were appeared and abundant electron dense granule in their matrix and sarcoplasmic reticulumn were visible. 60 minutes after release of 90 minutes tourniquet period, the majority of damaged mitochondrias were replaced by small sized new mitochondrias and electron dense granule were abundant in sarcoplasmic reticulumn. In human, the changes on the ultrastructure were reversible for at least a succeeding 90 minutes ischemic periods.

A retrospective analysis of 108 patients who had undergone transurethral prostatectomy for benign prostatic hyperplasia between January 1988 and December 1992 was performed to evaluate risk factors influencing intraoperative and postoperative morbidity and mortality. Of 108 patients complications occurred in 32 cases, with the morbidity rate of 29.6% but no death occurred. The most common postoperative complication was bleeding in 9 cases(8.3%) followed by incontinence in 7 cases(6.5%), capsular perforation in 4 cases(3.7%), failure to void in 4 cases(3.7%) and urethral stricture in 4 cases(3.7%). Risk factors which increased the morbidity of transurethral prostatectomy were age greater than 75 years and the presence of associated medical disease(p<0.05) but a resection time of more than 90 minutes, weight of resected tissue more than 30 gram and amounts of irrigating solution of more than 20 L did not increase the postoperative morbidity significantly. In conclusion, meticulous preoperative and postoperative cares are necessary because poor general condition increase the postoperative complications and long-term, prospective randomized studies are required to evaluate risk factors influencing postoperative morbidity after transurethral prostatectomy.

The measurements of B-type natriuretic peptide (BNP) or N-terminal proBNP (NT-proBNP), when taken together with conventional clinical assessment, may assist in making the prognosis and also for making serial adjustment of such treatment. But although such commercial assays are currently approved for the diagnosis of heart failure, the role of the natriuretic peptides for monitoring the success of congestive heart failure (CHF) therapy has not as yet been submitted for regulatory approval. Moreover, because of the intra-individual biologic variation of the BNP or because of multiple factors that affect the BNP levels, the magnitude of the change of BNP levels must be large to confidently interpret BNP changes within an individual, and just how large has not been determined. Yet the levels of plasma BNP and NT-pro BNP are well correlated with the concurrent haemodynamic measurements and indicators of left ventricular systolic function. Also, BNP and NT-pro BNP serve as significant prognostic information and it is possible that adjustment of anti-heart failure therapy according to serial measurements of BNP (in addition to the standard clinical assessment) may offer improved outcomes. Better understanding of the test characteristics is needed before we can effectively use this valuable test to guide therapeutic strategies.
