Patterns of branches and distributions of left coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. The left aortic sinus had only one orifice in all cases. The left coronary artery had mural coronray in 65% of cases. Type 3 of ramus interventricularis anteror was most frequent. Ramus coni arteriosi from the left coronary artery was more underdeveloped than that from right coronary artery. Right anterior ventricular branch was absent frequently, but when it was present it was composed of 1-2 small vessels. The left anterior ventricular branch was composed 2-5. It was difficult to define diagonal branch, and was present in 90% of cases. Type 3 of ramus circumflexus was most frequent. The ramus artrialis anastomoticus was present in 90% of cases. The rami atrialis could be divided into anterior and posterior group and incidence was only 47.5% and 30% respectively. The ramus marginalis sinister was present in 77.5% of cases. The anterior and posterior ventricular branch was composed of 1-3 and 1-4 respectively. The ramus posterior ventriculi sinistri was present in 82.5% of cases. Based on these results, the author depict typical arrangement of the left coronary artery in Korean.

Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.

Three cases of human embryo of Carnegie stage 13 were described. The CR length of these embryos were 3.0-5.3mm. The authors made a reconstruction model using photograph, photocopy and computer. These embryos were characterized externally by 4 limb buds and 4 pairs of branchial arches, and internally closed otic pits, appearance of venous valves, septum primum and foramen primum in the heart, beginning of the right and left lung buds, appearance of lens disk.

A case of thanatophoric dwarfism is presented. The previous gestation was polyhydramniotic and aborted spontaneously at 19th week. The aborted fetus showed marked micromelia. Present gestation was also polyhydramniotic and terminated by therapeutic abortion at 31th weeks due to skeletal deformity representing thanatophoric dwarfism. The fetus shows typical characteristics of thanatophoric dwarfism. Grossly the fetus shows marked micromelia, narrowed thorax with relatively normal length of trunk, and enlarged head. In the radiograph the femur shows characteristic ‘ telephone receiver’-like form. And the histological observations shows marked disturbances of the endochondral ossification.
