RÉSUMÉ
21 male adult goats were divided into the experimental group (11 goats) and control group (10 goats). The pressure-time of hyperbaric pretreatment was 700kPa-3min. The rates of the compressions and decompressions of hyperbaric pretreatments were l00kPa/min. The intervals between hyperbaric pretreatments and simulated divings which were repidly decompressed were 15min. The pressure-time of simulated diving was 600 kPa-60min. The rates of the compressions of the simulated divings were l00kPa/min and those of the decompressions were 60kPa/min. The results indicated that hyperbaric pretreatments might reduce the bubble formation and increased 5-HT concentrations which were caused by rapid decompression after simulated divings, and that other indexes such as morbility and mortality of decompression disease, platelet count of circulation, and bubble sound of blood flow on the precardium of the goats changed coincidently. These suggest that hyperbaric pretreatments could prevent goat's experimental decompression disease in some degree.
