Abstract

Anomalous lobulation of the lungs from the 395 cases (202 cases in male and 193 cases in female) of Korean fetuses aged from the 4th to the term of the prenatal life has been analyzed. 1. Of the left lung the incomplete oblique fissure has been observable in 38. 2 per cent out of the lungs 。bserved. 2. The horizontal fissure on the costal surface of the left upper lobe has been observable in one case out of the observed population. 3. The frequency of the occurrence of the fissure above the lingula of the left lung is 1. 3 per cent (5 cases out of the 395 left lungs). 4. The incomplete oblique fissure on the right lung is observable in 35.9 per cent out of the 395 right lungs. 5. In the 37.7 per cent of the right lungs the incomplete horizontal fissures are observable. 6. Of the lower lobe of the right lung the frequency of the horizontal fissure which is limited on the costal surface is 8 cases (2 per cent) out of the 395 right lungs. 7. In one case of the right lungs the lower lobe is divided into two lobes by a horizontal fissure.
