本研究從台灣海岸擱淺之鯨豚，選取新 鮮且能用之鯨豚肺臟供作實驗，共採得並 完成以硬乳膠供做鯨豚肺臟之支氣管樹鑄 型標本計有：弗氏海豚( lagenodelphis hosei)八個，花紋海豚( Grampus griseus) 三個，侏儒抹香鯨( kogia simus)三個、 瓶鼻海豚( Tursiops truncatus)及露脊鼠 海豚( Neophocaena phocaenoides)各一個 等。完成後之支氣管樹鑄型標本以中久喜 正一所建立的支氣管分枝的基本架構，可 了解到鯨豚肺臟支氣管分枝和一般路生哺 乳動物不同，外觀可分左右二大葉，每大 葉由前葉與後葉合而為一，兩側均無中間 葉與附葉小支氣管系統。右前葉之右前小 支氣管系統是獨立分支自氣管，其餘主支 氣管二分支自氣管。 The lungs of eight fraser’s dolphin ( Lagenodelphis hosei ), three Risso’s dolphin( Grampus griseus),three Dwarf sperm whale(kogia simus),one bottlenose dolphin( Tursiops truncatus) and one finless porpoise ( Neophocaena phocaenoides) were examinated. The cetacean lungs , unlike those of the other domestic species, are not clearly subdivided by deep interlobar fissures into lobes, although there are occasionally external indications of a lobar arrangement. However, the right and left lung may be bilaterally considered to consist of two lobes, namely an apical (cranial) and a diaphragmatic (caudal). Both lobes are united to form a single one. The middle and accessory lobe bronchioles are lacking on either side. The principal bronchus of right apical lobe is solitary arising from the trachea. Despite of the right apical lobe, the remaining principal bronchi of right and left lobe are bifurcation from the trachea.
