In Hannover/Germany in 1976 a so called "Society for Regenerative Hyperbaric Therapy" (Gesellschaft für Regenerative Uberdruck-Therapie) subjected 20 patients within two coupled multi-place chambers to a simulated hyperbaric environment, equivalent to a maximum of 4 ata, followed usually by gradual reductions of the pressure. The patients were of an average age of 67.2 years and were afflicted by various disorders. During one of the "dives" a patient developed air embolism of the central nervous system. During ensuing confusion of the chamber was opened suddenly, with resultant explosive reduction of the high pressure. This resulted in five letal accidents of decompression sickness. Post mortem examination revealed diffuse distribution of gas bubbles throughout the entire body. By elecronmicroscopy each bubble was covered by an osmiophilic coat. Post mortem findings are discussed and correlated with well-known and new clinical symptomes. These observations present for the first time fatal accidents of decompression sickness in humans, associated with hyperbaric air-therapy. 相似文献

The authors compared the effects of alcoholic drinks rich in fusel oil with the effects of diluted pure alcohol of the same quantity on 19 clinically healthy university students. The investigations utilized EEG and physiopsychic testing methods. The clinical symptoms were observed both under the effect of drinks and in a crapulous state ("hang-over"). It was found that alcoholic drinks rich in fusel oil can produce a more deviating EEG curve, an increased worsening of physiopsychic performance and of clinical and subjective symptoms. The necessity of regular quality control of alcoholic beverages is pointed out. 相似文献

In 1971, 44 percent of workers who had been currently entitled to social security disability insurance (DI) benefits for 1 year or more also received benefits from at least one other source. Their average disability insurance benefit was higher than that of persons who received only DI benefits. On the average, total benefits to those receiving multiple benefits were double the amounts paid to those receiving only DI benefits. The combined benefits for the former produced median replacement rates about 50 percent larger than the median replacement rates for the latter. High replacement rates--defined here as more than 80 percent of predisability earnings replaced by benefit--predominate among those with multiple benefits. Considering replacement rates based solely on disability insurance benefits substantially understates the extent to which benefits from public and private programs actually replace predisability earnings. Replacement rates based solely on DI benefits are generally higher for those receiving DI benefits only than for persons receiving multiple benefits. Limiting DI benefits to the replacement rate from DI benefits alone is disadvantageous for persons who receive only DI benefits, compared with those who also receive other benefits. 相似文献
