摘要
１９９０年，作者于辽东湾采集了１０头江豚标本，分别测定了其骨骼、皮肤、肌肉、肝脏、肺、肾、心、胃、肠、胰、脾、肾上腺及生殖腺等１３种组织中Ｃａ、Ｓｒ、Ｍｇ、Ｐ、Ｋ、Ｎａ６种元素的含量，详细分析了骨骼及其他各组织中的Ｃａ／Ｍｇ值、Ｃａ／Ｋ值、Ｃａ／Ｐ值、Ｃａ／Ｎａ值和Ｃａ／Ｓｒ×１００值。结果表明，Ｃａ、Ｓｒ、Ｍｇ、Ｐ，Ｋ在骨骼中累积率最高，钾在肌肉中具有高累积，Ｓｒ、Ｃａ在肌肉中累积率最低；Ｍｇ累积率最低的组织是生殖腺，Ｐ累积率最低的组织是肠，而Ｋ在骨骼中，Ｎａ在肌肉中的累积率均高于其他组织。分析结果还显示，Ｃａ／Ｍｇ值最高的是骨骼，最低为肌肉，Ｃａ／Ｐ值最高的是骨骼，最低的是肌肉和胰脏，Ｃａ／Ｋ值最高为骨骼，最低为脾Ｃａ／Ｓｒ×１００值最高为肺、最低为肠，而Ｋ／Ｎａ值最高为肌肉，最低为骨骼，在骨中Ｃａ／Ｐ值大约为１，类同于猫和人类。
The contents of Ca,Sr,Mg,P,K and Na in the bone,skin,muscle,kidney.liver.lung,heart,stomach.instestine,pancreas,spleen adrenal and gonad of the finless porpoise(Neophocaena phocaenoides) were analysed respectively.The finless porpoise were captured off the coast of Xing Cheng in Liaodong Bay in 1990.Moreover,the ratio of Ca/Mg,Ca/K,Ca/P,Ca/Na and Ca/Sr×100 were calculated.The results indicated that the ratio of Ca/Mg was the lighest in the bone and the lowest in the muscle.the highest Ca/P was in the bone and the lowest in the muscle and pancreas.The ratio of Ca/P in the bone was about 1 which is similar to the human and the cat's.
