A study was undertaken to assess the incidence of inflammation and dysplasia in retained mucosa after double-stapled ileoanal reservoir (IAR) for mucosal ulcerative colitis (MUC). Between September 1988 and February 1992, 56 patients with MUC underwent an IAR. Forty-five patients had a double-stapled IAR (DS-IAR), seven patients had a transanal pursestring(More)
Blood flow in vasa recta capillaries of the exposed renal papilla of young antidiuretic rats (n = 18) was determined by an adaptation of the video-photometric technique of Intaglietta. The erythrocyte velocity and capillary diameter in vasa recta (n = 97) were measured at the same location by means of fluorescence video microscopy, with fluorescein-labeled(More)
We used a PCR-based technique to isolate 18 microsatellite loci for the largemouth bass, Micropterus salmoides. These loci were characterized using sampled populations in Florida and Wisconsin. The mean number of alleles at a locus was 8 for the sample from Florida and 5 for the samples from Wisconsin. The observed heterozygosities were 0.57 and 0.33 for(More)
Furosemide caused a significant reduction in mesenteric blood flow and conductance as early as 10 min after administration. When fluid losses were not replaced, conductance continued to decline. In volume-repleted animals, conductance fell initially but failed to decrease further. Thus, furosemide decreases mesenteric conductance in two ways: a small early(More)
A study was undertaken to assess the etiology, optimal diagnostic method, and incidence of healing of perianal ulcers in HIV-seropositive men. Between March 1990 and December 1991, 26 HIV-seropositive homosexual or bisexual males were referred with perianal ulcerations. According to CDC criteria, three (12 percent) were Class II, six (23 percent) were Class(More)
Vasa recta erythrocyte velocities (VRBC) in the exposed renal papilla of anesthetized water-loaded rats were determined before and 60 min after intravenous administration of a prostaglandin synthesis inhibitor (indomethacin, meclofenamate) or the inhibitor vehicle alone. The change in VRBC of ascending and descending vasa recta for the inhibitor group [-17(More)
We describe 10 microsatellite loci for Panulirus argus (Caribbean spiny lobster). The number of alleles at each locus ranged from four to 39 (mean = 21.8) in 89 juvenile specimens collected at two different times at a recruitment site in south Florida. Levels of expected and observed heterozygosities ranged from 0.48 to 0.96 (mean = 0.83) and from 0.32 to(More)
A furnace oil, a dewaxed heavy paraffinic distillate, and a solvent-extracted lubricant base oil induced skin tumors in 9/43, 26/48, and 1/47 male C3H mice, respectively, during lifetime skin-painting bioassays. An initiation/promotion (I/P) bioassay was conducted to assess the I/P potential of these materials. During a 28-week initiation bioassay, groups(More)
Catalytic reforming is a refining process that converts naphthenes to aromatics by dehydrogenation to make higher octane gasoline blending components. A portion of this wide boiling range hydrocarbon stream can be separated by distillation and used for other purposes. One such application is a mixture of predominantly 9-carbon aromatic molecules (C9(More)
OBJECTIVE To find out if clearance of surgical colectomy specimens with xylene gave a higher yield of lymph nodes and more accurate staging than the traditional step-sectioning technique. DESIGN Consecutive open study. SETTING Private hospital, United States. MATERIAL 84 specimens from colonic resections, 4 of which were total colectomies and the(More)
