Treatment of proctalgia fugax with topical nitroglycerin: report of a case.

Purpose: We report a single case of proctalgia fugax that responded to 0.3 percent nitroglycerin ointment.

Methods: Case report.

Chloride transport activation by plasma osmolarity during rapid adaptation to high salinity of Fundulus heteroclitus.

Transition from low salt water to sea water of the euryhaline fish, Fundulus heteroclitus, involves a rapid signal that induces salt secretion by the gill chloride cells. An increase of 65 mOsm in plasma osmolarity was found during the transition. The isolated, chloride-cell-rich opercular epithelium of sea-water-adapted Fundulus exposed to 50 mOsm mannitol on the basolateral side showed a 100% increase in chloride secretion, which was inhibited by bumetanide 10(-4) M and 10(-4) M DPC (N-Phenylanthranilic acid).

Regulation of C1q receptor expression on human polymorphonuclear leukocytes.

The C1q receptor (C1qR) is expressed on a variety of cells, including polymorphonuclear leukocytes (PMN), in which stimulation by the C1qR leads to activation as measured by superoxide production. To investigate the expression and modulation of the C1qR on PMN, the binding of biotinylated C1q to PMN in suspension was measured by flow cytometry. Biotinylated C1q bound in a saturable and specific manner to PMN and the use of low ionic strength buffers enhanced binding.

Successful pregnancy and vaginal delivery after heart transplantation.

Successful pregnancy and delivery in women with serious cardiovascular diseases have been reported. We describe here a patient with a transplanted heart, treated with cyclosporine and prednisone, who underwent pregnancy and vaginal delivery with good outcomes for mother and infant.
