We reported previously that following ileocystoplasty the structure and pharmacologic response of the implanted ileum changes towards that of the bladder. Specifically, the relaxation response to alpha adrenergic (methoxamine) and purinergic (ATP) stimulation reverses to a contractile response one month after the ileal segment is surgically made part of the(More)
We have designed a venous compression device implantable at the base of the penis outside the tunica albuginea. Because it does not require exposure of individual veins for ligation, the risk to the cavernous nerve is practically nil. It occludes the venous return only temporarily, and thus collaterals are less likely to occur. In this preliminary acute(More)
Fetal liver transplantation was attempted in 7 patients with aplastic anemia. 4 of these patients showed a partial response as evidenced by decrease in blood transfusion requirements and increase in the peripheral blood counts and hematopoietic cells in the bone marrow. Bone marrow culture studies revealed evidence of a temporary mixed lymphoid chimerism(More)
From March 1995 to March 1996 24 women aged 29–73 years with stress urinary incontinence underwent a modified vaginal wall sling procedure following videourodynamic evaluation. Of these 24, 2 had stress urinary loss due to urethral hypermobility (UH), 3 had intrinsic sphincter deficiency (ISD) and 19 had both UH and ISD. Thirteen (54%) had preoperative urge(More)
Despite occasional case reports, vasodilator therapy of primary pulmonary hypertension remains unsatisfactory. Nifedipine, a calcium channel antagonist, has recently been recommended for the treatment of primary pulmonary hypertension. Transient mild side effects to this drug have been known. In this report we describe a case of primary pulmonary(More)
PURPOSE We evaluated the diagnostic efficacy of pudendal nerve somatosensory evoked potential testing in patients with voiding and/or erectile dysfunction. MATERIALS AND METHODS A total of 55 consecutive patients with voiding and/or erectile dysfunction underwent pudendal nerve somatosensory evoked potential testing during a 2.5-year period. P1 latencies(More)
This article examines various kinds of chemical sensors, their mechanism of operation and the ways to improve their performance. It reports the results of exploratory investigation of binary composite polycrystalline thick-films such as SnO2-WO3, SnO2-In2O3, and SnO2-ZnO for the detection of volatile organic compound (isopropanol) are reported. It also(More)
High quality bulk single crystals of novel NLO semiorganics : L-arginine tetrafluoroborate (L-AFB) and L-histidine tetrafluoroborate (L-HFB) measuring 78 × 50 × 35 mm have been successfully grown from solution by temperature lowering methods. Solubility curves of these materials have been determined in different solvents, such as water, ethanol and acetone(More)
