Simple clinical method of measuring gastric emptying of solid meals.

The radioisotope techniques used for the measurement of gastric emptying of solid meals in man require complex and expensive scintiscanners of cameras. We have evaluated a simple technique which uses a fixed scintillation detector and compared the results with those obtained from a gamma camera. The rates and patterns of gastric emptying recorded by the two methods correlated well in both healthy volunteers (mean r= 0.95) and patients with duodenal ulcer (mean r =0.89). The scintillation detector provides a reliable and inexpensive method for measurement of gastric emptying of solid meals.

Distribution of R plasmids among the O-antigen types of Escherichia coli isolated from human and animal sources.

The O-antigen types of 600 independently isolated Escherichia coli strains from human feces have been determined, and the types have been related to the antibiotic resistance patterns of the strains. The relative abundance of each O-antigen type differed in the susceptible and resistant series of strains. The majority (86%) of the resistant strains carried R plasmids. Resistant E. coli (20.3%) were found associated with O-antigen types 8, 9 and 101, whereas the susceptible strains covered a wide range of O-antigen types. Examination of 174 resistant strains isolated from calf feces also showed a prevalence of O-antigen types 8, 9, 101 (24.1%), and it seems probable that strains expressing these three O-antigen types commonly carry R plasmids in the alimentary tracts of man and calves. The number of strains not typeable with the O sera available were similar in the human (12.5%) and the calf (11.5%) series. There are no grounds for distinguishing "human" from "calf" E. coli on the basis of their O-antigen reactions.
