A total of 97 species of flies collected in Korea since 1919 is described which consists of the collections by Kobayashi, Hori and the author. They include 19 species belonging to 12 genera of the family Calliphoridae, 38 species belonging to 15 genera of the family Sarcophagidae and 40 species belonging to 14 genera of the family Muscidae. The specimens were identified according to the male genitalia, which generally show little variations among the flies of the same species, and were illustrated. The geographical distribution and localities in Korea of all the species are presented, and the medically important species are discussed in detail. Of these flies, the calliphorid species in Korea are described and illustrated in this paper. The author found newly 8 species of calliphorid flies including a new species. As for the families Sarcophagidae and Muscidae, the descriptions on these will be published in part II and part III, respectively, in the near future.
Twenty species belonging to the genus Musca Linné are reported from Tailand with taxonomic key. This study is based on the specimens available in the authors' collection and 8 species are the new records from this country. The newly recorded species are Musca interrupta pilifacies, M. lucens, M. fasciata, M. pattoni, M. planiceps, M. xanthomelas, M. bezzii and M. convexifrons.
Effect of carbon monoxide on the redox state and blood flow in the renal cortex of the rabbit was examined by the fluorometric method. By a short-period (1-3 min) inhalation of CO in concentrations over 1%, the following were revealed: (1) Reduced pyridine nucleotide was increased, (2) oscillatory change of the reduced pyridine nucleotide, which is characteristic for the histotoxic reaction, developed, and (3) extent of the fluorescence changes tended to be in proportion to the concentration of CO, but no change was caused by inhalation of CO in lower concentrations (0.1%, 0.5%) even if the inhalation was continued for 30 min. As to the blood flow, CO in concentrations over 0.5% decreased it, whereas anoxia due to nitrogen increased it. Some implications were discussed from toxicological points of view on the results obtained.
As a part of the work designed to find a material suitable for a dental implant, tissue reaction of various kinds of polysulfone composite materials has first been studied by implantation in the femur of rats and in the mandible of rabbits. Histological examination showed that the porous polysulfone composite containing 20 wt.% of tricalcium phosphate exhibited a favorable osteogenesis. The tooth replica implants made of this composite material were inserted into the extraction sockets of dogs. During 5.5 months of observation, horizontal or diagonal orientation of periodontal fibers, no epithelization, and no alveolar bone resorption were noted. This study suggests a promising feasibility of the polysulfone-calcium phosphate composite material as a dental implant material.
An autopsy case of renal cancer complicated with multiple oral ulcers is presented. Although serological tests were not available, double viral infection with herpes simplex virus and cytomegalovirus was suspected as causal agents in the retrospective examination. This infection may be a complication in the prolonged stage of cancer patients.
