Autoradiographic study was performed in order to know the distribution of exogenous C(14)-glucose by lung fluke, Paragonimus westermani, incubated in Tyrode medium containing 10 uCi/ml of labeled substance. After 1 hour incubation at 37C, microautoradiographs of this fluke showed that black grains derived from radioactive carbon were accumulated mainly in the parenchyme and subcuticular musculature. The muscular tissues such as oral sucker, pharynx and ventral sucker revaled considerable density of fine grains. Slight radioactivity was also observed in the regions of ovary, testes, vitelline follicles, eggs in uterus, intestinal ceca, and even in excretory bladder. Structures showing the least activity included the cuticle and uterine tubules of this fluke.

The growth plate is responsible for longitudinal bone growth and is involved in 6–15% of children's fracture. Of these injuries, 25–35% have been reported to result in some shortening or deformity, but in only 10% are the deformities sufficiently severe to lead to functional problems. The problem of repair of a demaged growth plate in children has never been adequately solved. The purpose of this study is to clarify that allograft of cultured chondrocytes can survive in the growth plate defect and can prevent the angular deformity by avoiding the formation of bone bridge. The chondrocytes were obtained from the rib cartilage of rabbit weighing 500g. The chondrocytes were cultured by socalled micromass culture method. The rabbits were divided two groups; the group I in which medial proximal tibial growth plate was destroyed, and the group II in which the cultured chondrocytes were transplanted into the right medial proximal tibial physeal defect. Each group has 10 rabbits. The tibial growth was observed grossly, radiologically and histologically until 16 weeks after graft. The angular deformity was observed from 3 weeks after operation and histologically the fusion of growth plate was observed in all of group I. In group II, there were no angular deformity and no fusion of growth plate in 7 out of 10 rabbits. Allografted cultured chondrocytes survived and produced matrix in the physeal defects. Through this study it was inferred that allograft transplantation of cultued chondrocytes in the iatrogenical physeal defect is a useful method to keep the physeal growth without cessation. However, further studies will be necessary to prove that the longitudinal growth potential resides in the transplanted chondrocytes as growth plate cartilage.

Throughout medical science today there is increasing emphasis upon understanding the familial and associated genetic interplay in various disease processes. We observed a case of Legg-Calve-Perthes disease developed in monozygotic male twins. They have some mirror image of each other, for example hair whorl and involved hip. This report of the disease which is present in mirror fashion in idenitical twins illustrates enen more vividly the genetic interaction in the disease. Therefore, those who are aware that Legg-Calve- Perthes disease has appeared in a family should keep in mind the probability of the disease developing in another member.

In an attempt to investigate the specific antigenic substance of Fasciola hepatica, Ouchterlony tests and immunoelectrophoretic analyses were carried out. Crude Fasciola antigen was prepared and fractionated by Sephadex G-200 column to Antigen I, II and III according to protein content. Crude antigens of Paragonimus westermani, Clonorchis sinensis and Paramphistomum sp. were also prepared for control and absorption study. Antiserum was prepared by injecting 0.5 ml of crude Fasciola antigen with same amount of complete Freund's adjuvant in rabbits, 10 times at an interval of l week. The results obtained in this study were as follows: Crude Fasciola antigen reacted with antiserum with 9 precipitin bands by Ouchterlony test and with 11 bands by immunoelectrophoresis. Cross reaction was observed between Paragonimus, Clonorchis and Paramphistomum antigens and anti-Fasciola rabbit serum respectively. By Ouchterlony test, 3-4 cross reacting bands were found. Anti-Fasciola sera which were absorbed with respective Paragonimus, Clonorchis and Paramphistomum antigens, reacted with Fasciola crude antigen. Ouchterlony test gave 5-6 precipitin bands. Further reaction between Fasciola antigen and antiserum absorbed with the above 3 antigens concomitantly gave 5 precipitin bands by Ouchterlony test and 7 bands by immunoelectrophoretic analyses. Fractionated Fasciola antigens (Antigens I, II and III) reacted with anti-Fasciola rabbit serum in immunoelectrophoresis. Antigen I, II and III gave 2, 3 and 5 precipitin bands respectively. Anti-Fasciola rabbit serum which was absorbed with 3 trematodes antigens gave, by immunoelectrophoresis, 1 band with Antigen I, 2 bands with Antigen II and III of Fasciola hepatica. From the above results, it is concluded that Fasciola hepatica possessed the specific antigenic substance not cross-reacted with other trematodes.
