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 sensitivity of immunodiagnosis in cats experimentally infected with Paragonimus westermani, agar-gel precipitin reaction were studied. Metacercariae of P. westermani were administered to cats in various doses(2-100 metacercariae per cat) and antisera were obtained at an interval of a week. Precipitin bands appeared in homologous antigen-antibody in experimental paragonimiasis between 3 and 5 weeks after infection in all the cats. Almost all the cases in which a large number of worms were detected, showed strong reactions as revealed by deeply stained bands. Precipitin reactions did not necessarily parallel with the number of worms detected. This may be attributable to the individual difference of a cat's conditions. Very weak precipitin reactions were noticed between Clonorchis antigen and Paragonimus antisera of cats, but no reactions were noticed between Paragonimus antigen and Clonorchis antisera of cats or rabbits.

In an attempt to investigate the antigen-antibody relations and the value of immunodiagnosis for several helminths, Ouchterlony tests and immunoelectrophoreses were carried out. Taenia saginata, Cysticercus sp. of cestodes, Clonorchis sinensis, Fasciola hepatica and Paramphistomum sp. of trematodes,and Ascaris suum of nematodes were used as antigens. On the other hand, antisera were obtained by injecting 0.5 ml each of the above antigens and the same amount of complete Freund's adjuvant into rabbits ten times at an interval of one week. The result obtained in this study are as follows: A larger number of precipitin arcs were demonstrated in homologous antigen-antibody reactions than in heterologous antigen-antibody reactions both in Ouchterlony tests and immunoelectrophoreses. Gross reactions were observed between the different species of the same class, but no cross reactions were noticed when the classes were different with one or two exceptions, such as between T. saginata, F. hepatica and A. suum. In A. suum, the difference between the male and female was more distinct in Ouchterlony test and immunoelectrophoresis than in the examination of organs such as genital organ and coeliac fluid. Immunoelectrophoresis revealed specific arcs and higher sensitive reaction than Ouchterlony test, and was considered to be a more valuable method for identifing species and immunological diagnosis.
