• Description:
  The influence of some active materials in cotton dust on the development of byssinosis was investigated. Surface activity of cotton dust components: catechin (120809), rutin (153184), and gossypol (303457) was measured alone and with dipalmitoyl-lecithin (2644646) (DPL), the major constituent of lung surfactant. Surface tension area hysteresis curves were recorded. The effect of single and repeated washings with ammonium-hydroxide (1336216) and sodium- hydroxide (1310732) on surface activity was determined. All three cotton components were surface active. Gossypol was the most active. Surface tensions were higher for the cotton components than the surface tension produced by dipalmitoyl-lecithin. The hysteresis of DPL films was reduced by rutin and abolished when catechin was added; however, gossypol increased the hysteresis area. Only a small portion of the surface active material was removed from cotton dust after a single washing with ammonium-hydroxide. Repeated washings reduced the surface activity to 10 percent. Repeated washings of cotton dust with sodium-hydroxide removed only 60 percent of the surface activity. The authors conclude that gossypol may be the cotton dust component responsible for surface activity of cotton dust. The role of surfactant loss in development of peripheral lung disease remains to be studied. [Description provided by NIOSH]
