Attitudes toward minorities: a comparison of homosexuals and the general population.

As a prelude to a media campaign to improve the public image of gays, a gay rights organization in Columbus, Ohio, constructed a questionnaire to assess perceptions of and attitudes toward gays and various other minority groups including blacks, Jews, women, communists, and recovering alcoholics. The questionnaire was administered to two samples in the central Ohio area: a sample of the greater Columbus population at large, and a sample of gays and lesbians. This article reports on the comparative findings from these two samples.

Laparoscopic removal of a large colonic lipoma. Report of a case.

A 72-year-old white male was found to have a 6-cm submucosal mass at 35 cm on screening sigmoidoscopy. The lesion had all the characteristics of a submucosal lipoma. Instead of performing a laparotomy with its potential morbidity, the lesion was removed laparoscopically in its entirety without untoward operative sequelae. Laparoscopic techniques have had a profound impact on the treatment of patients with surgical disorders. This new technology can be applied to selected patients with colorectal diseases.

Influence of R-plasmid RP1 of Pseudomonas aeruginosa on cell wall composition, drug resistance, and sensitivity to cold shock.

R-plasmid RP1 was transferred to Pseudomonas aeruginosa cells, as indicated by their resistance to carbenicillin, ampicillin, cephaloridine, kanamycin, and tetracycline, and by the presence of a periplasmic beta-lactamase. The wild-type cells (RP1-) were lysed by ethylenediaminetetraacetic acid but not by ethylene-glycol-bis(2-aminoethyl ether)-N,N-tetraacetic acid, whereas cells carrying the plasmid (RP1+) were resistant to both these chelating agents. RP1+ and RP1- strains were both sensitive to the lytic action of polymyxin B and the lethal action of cold shock, but the effect was less marked in the RP1+ cultures. A proportion of the RP1+ cells surviving cold shock lost resistance to carbenicillin, tetracycline, and kanamycin. The chemical composition of whole cells and cell walls of RP1+ differed from that RP1- in the content of cation, phospholipid, and markers for lipopolysaccharide and peptidoglycan. Differences in cell wall composition, response to ethylenediaminetetraacetic acid and polymyxin B, and the effects of cold shock are all compatible with the hypothesis that RP1 confers changes in the cell envelope, probably in the outer membrane, of P. aeruginosa.
