Determination of blood levels of intracellular enzymes is an appropriate method to evaluate tissue and organ damage. To show systemic tissue damage resulting from intestinal ischemia-reperfusion, New Zealand rabbits underwent 60 min intestinal ischemia and 60 min reperfusion. ⋯ It is difficult to claim that enzymes arise from the intestine, but an increase of CK, LDH, and later of AST without any increase in alanine aminotransferase levels during ischemia suggests that their primary source is the injured intestine. Increased levels of plasma enzymes do not provide exact information about the location, but do reveal the presence of an injury.

Lichen sclerosus et atrophicus in children with phimosis and hypospadias.
This prospective study was designed to evaluate the incidence of lichen sclerosus et atrophicus (LSA) in a pediatric population with hypospadias and phimosis in order to discuss the indications for circumcision and utilization of preputial skin for urethral surgery. All 115 boys, 55 with congenital phimosis, 45 with acquired phimosis, 13 with hypospadias, and 2 with recurrent chronic balanitis, underwent full-thickness biopsies of the foreskin that were examined by a single pathologist. Of the patients with acquired phimosis, 88% showed inflammatory features in the foreskin; 60% had LSA. ⋯ Of the patients operated upon for hypospadias, 61% showed histologic findings of chronic inflammation of the foreskin and LSA was evident in 15%. The high incidence of LSA in the prepuce of patients with phimosis suggests that circumcision should be performed to correct this disease. The frequent presence of chronic inflammation is a possible cause of stenosis when the foreskin is used to perform a urethroplasty in patients with hypospadias.
