Sulindac. A potentially renal-sparing nonsteroidal anti-inflammatory drug.

Three patients experienced rapidly reversible azotemia related to the use of naproxen or ibuprofen but tolerated full-dose sulindac. This article discusses renal toxicity of nonsteroidal anti-inflammatory drugs (NSAIDs), with emphasis on the role of inhibition of prostaglandin synthesis, and reviews evidence supporting a renal-sparing property of sulindac. The current literature assumes that all NSAIDs possess a similar potential for renal toxicity. The data presented suggest that sulindac has less potential for renal toxicity and may be the preferred NSAID for use in patients with impaired renal function.

N-acetylcysteine and clotrimazole inhibit sickle erythrocyte dehydration induced by 1-chloro-2,4-dinitrobenzene.

Clotrimazole, a specific inhibitor of the Ca(2+) activated potassium (Gardos) channel, and the antioxidant N-acetylcysteine were found to inhibit the in vitro formation of high-density sickle cells induced by treatment with 1-chloro-2,4-dinitrobenzene (CDNB). The CDNB induced leakage of K(+) can be inhibited by treatment of SS erythrocytes with 20 mM N-acetylcysteine. We conclude that the effect of N-acetylcysteine in preventing K(+) efflux and formation of high-density sickle cells is related to its ability to protect the Gardos channel from oxidative damage caused by diminished levels of reduced glutathione. This effect is due to the ability of N-acetylcysteine to maintain an appropriate level of reduced glutathione and its direct antioxidant activity.

The use of indomethacin, sulindac, and tamoxifen for the treatment of desmoid tumors associated with familial polyposis.

Seven familial polyposis patients with desmoid tumors were treated with indomethacin, sulindac, or tamoxifen either as single agents or in combination. Serial computed tomographic (CT) scan examination was employed for objective measurement of tumor size since physical examination alone was an inaccurate means to evaluate intraabdominal and retroperitoneal desmoids. Only one patient with minimal tumor burden demonstrated a favorable response with complete resolution of an abdominal wall desmoid.

The variable fine structure of elastin visualized with Verhoeff's iron hematoxylin.

Verhoeff's iron hematoxylin (VIH) followed by lead citrate (LC) applied to epoxy thin sections stained the dense component of elastic fibers heavily and the peripheral microfibrillar component lightly in guinea pig trachea and mouse testis fixed with a glutaraldehyde-osmium tetroxide sequence. This method stained large fimbriated fibers beneath tracheal epithelium, small fibers and stacked aggregates thereof in the deep lamina propria, cartilage and adventitia of the trachea and large stacked fibers in the fibroelastic band of the trachea. Fibers of the fetus differed from those of the adult, especially in the subepithelial elastic lamina of the trachea. Elastic fibers were intimately associated with fibroblasts and particularly slender fibroblast processes in tracheal stroma and with chondrocytes in tracheal cartilage. Fibroblasts associated with elastic fibers in the tracheal subepithelial lamina propria were often closely bordered by eosinophils, mast cells, or monocytes. Occasional mast cells extended slender processes around elastic fibers in the subepithelial lamina propria. In mouse testis and in many regions of the trachea, small elastic fibers were identified which were below the limits of resolution for the light microscope and were not apparent at the ultrastructural level in routinely stained thin sections.
