The calliphorid flies collected from different localities in Thailand were examined to study their medical importance as well as to study from the zoogeographical standpoint of view. Fourty-two species of 15 genera, Bengalia，Calliphora, Catapicephala, Chrysomya, Hemipyrellia, Hypopygiopsis, Lucilia, Melinda, Onesia，Phumosia，Pollenia, Polleniopsis, Tainanina, Tricycleopsis and Verticia belonging to both the subfamilies Calliphorinae and Chrysomyinae were found in Thailand. Many species are newly recorded from this country. The little known species, which are redescribed in detail with the illustration of the male genitalia and female ovipositors, and the key, which is revised to the gene1a and species, are also presented in this paper.
The purpose of this experiment was to examine the growth of condylar, epiphyseal, and spheno-occipital synchondrosal cartilages cultured on medium BGJ. Materials from 12 neonatal rabbits were cultured for 7 days on this medium with the addition of 0, 10, or 20% fetal calf serum.
Epiphyseal cartilages cultured with the addition of 20% fetal calf serum showed slightly better maintenance of in situ state, though little morphological changes were observed during 7 days.
Spheno-occipital synchondrosal cartilages cultured with the addition of 10% or 20% fetal calf serum were histologically relatively similar to in situ state than those cultured without fetal calf serum, but no growth in length and width of these cartilages was observed. On the other hand, cultured condylar cartilages showed the least maintenance of histological and histochemical features.
It was assumed that medium BGJ was not a recommendable medium for the organ culture of condylar cartilage.
To evaluate the diagnostic value of cytological study of the goiter in pediatric practice, percutaneous aspiration biopsies were performed on 22 patients.
In 13 of 14 patients whose physical and serological examinations suggested chronic thyroiditis, abundant lymphoid cells including germinoblasts and germinocytes were observed in the smeared preparation of aspirated materials. A few degenerated follicular epithelial cells, reticuloendothelial cells, and plasma cells were also occasionally seen. No fibrous elements were observed. In 5 of 8 patients with simple goiter, only a few intact follicular epithelial cells were seen. The procedure was simple, well tolerated by the patients, and there were no complications.
Based on these results, it was concluded that percutaneous aspiration biopsy may be one of the useful methods for the diagnosis of chronic thyroiditis in childhood.
The author examined the cerebral schistosomiasis japonica (CSJ) in the Philippines which is one of the areas heavily infected with S. japonicum.
Seventy-five subjects were selected randomly from 307 patients with CSJ, who showed neurological symptoms such as convulsions, paroxysmal disturbance of consciousness and hemiparesis.
The mean age of the subjects was 33. Of the 71 patients who had paroxysmal diseases, 54 had convulsions, in 33 of which it was of the Jacksonian type, and 24 had psychomotor seizures and 1 autonomic seizures. Thus, 58 patients or 82% of the paroxysmal disease group showed a sign of the localized lesion of the brain.
Fifty-one patients (72%) of this group had attacks more than once a month, and the onset of the paroxysmal disease was later than 20 years old in 49 (69%).
EEGs were judged as abnormal in 24 (32% of total subjects), borderline in 13 (17%) and normal in 38 (51%). The characteristic abnormal or borderline findnigs of EEG were random and paroxysmal slow waves with asymmetry.
Discussion was made in reference to the strong suspicion that the cerebral symptoms of the subjects, the paroxysmal diseases in particular, were a syndrome associated with Schistosoma japonicum and to the difference between CSJ in Japan and that in the Philippines.
