The carbonic acid-base balance and the concentrations of Na and Cl were studied in 3 fluids, plasmatic, pericardial and peritoneal, sampled from 2 species of amphibians: Pleurodeles waltl and Xenopus laevis. In Pleurodeles the pericardial and peritoneal fluids are in a state of marked metabolic alkalosis, the carbonate alkalinity being up to 10 times higher in the serosal fluids than in the plasma, whereas PCO2's are very close in the 3 fluids. The Cl concentration is markedly lower in the serosal fluids than in the plasma. In Xenopus, the metabolic alkalosis of the serosal fluids also exists, but to a much lower extent than in Pleurodeles. These observations lead to further researches in the field of morphometry, physicochemistry and physiology.
对从两种两栖动物（虎纹钝口螈和非洲爪蟾）采集的三种液体（血浆、心包液和腹膜液）中的碳酸酸碱平衡以及钠和氯的浓度进行了研究。在虎纹钝口螈中，心包液和腹膜液处于明显的代谢性碱中毒状态，浆膜液中的碳酸盐碱度比血浆中高多达10倍，而三种液体中的PCO2非常接近。浆膜液中的Cl浓度明显低于血浆。在非洲爪蟾中，浆膜液的代谢性碱中毒也存在，但程度比虎纹钝口螈低得多。这些观察结果促使在形态测量学、物理化学和生理学领域开展进一步研究。
