The author investigated 100 hypertensive patients (199 eyes) on their brachial blood pressure, ophthalmic blood pressure, Fritz's index, sclerotic changes in retinal vessels, and P.S.P. test. The vascular changes of the retina were classified according to the Keith-Wagener scheme, and the sclerotic changes were represented by the point system. For the evaluation of circulatory status of the carotid system, r(s)/r(d)-carotis ratio and cerebrovascular resistance (CVR) were also calculated. The relationships between these data were studied and their results were as follows: (1) There was a linear correlation between mean ophthalmic blood pressure and mean brachial blood pressure, the correlation coefficient being plus 0.83. (2) There was also a linear relationship between fundus changes and mean ophthalmic blood pressure. The more advanced the grade of Keith-Wagener classification and the sclerotic changes, the higher the mean ophthalmic blood pressure. The rise of the mean ophthalmic blood pressure as more marked in K-W grade III, IV, and in grade IV sclerosis. (3) There was a close relationship between P.S.P. test, mean ophthalmic blood pressure and brachial blood pressure. The renal function was disturbed in patients with higher mean ophthalmic blood pressure. (4) The decrease of r(s)/r(d) carotis was always accompanied by the increase of Fritz's index, severity of sclerotic changes in the retina and advancement of the grade of K-W classification. (5) In patients with normal P.S.P. value, there was no single case of advanced sclerosis (more than 10 points of sclerosis). r(s)/r(d) carotis ratio was generally over 1.0. In patients with low P.S.P. value, however, the retinal vascular sclerosis shoshowed more marked changes, and r(s)/r(d) carotis ratio failed below 1.0. (6) Generally, there was a tendency of the increase in the CVR in accordance with the increase in Fritz's index and sclerotic changes. Moreover, functional disturbance of the kidney was usually associated with higher CVR. (7) The author proposed the possibilities that CVR value more than 0.5 or r(s)/r(d)-carotis ratio below 1.0 might represent the advanced sign of vascular sclerosis, disturbance of kidney function.

The intradermal studies with the fraction of Ascaris lumbricoides and Toxocara canis were performed to human and dog, and the following results were observed. Wheal and erythema were appeared in the cases of ascaris infection or who had past history, but not in the ascaris free before. The size of wheal reached to peak 30 minutes after the injection. The crude antigen had specificity and showed no cross reaction. The crude antigen cause the strongest and largest reaction than the other substances; protein, polysaccharide and the mixed antigen. No cutaneous reaction was observed with the fraction of polysaccharides. The size of wheal did not parallel with the worm burden. The skin reaction was appeared four weeks after the infection.

The authors made a study on the species and distribution of helminths in Korean native cattle. The feces and internal organs from 1,755 heads were examined in slaughter plants of Taejon district. The results are summarized as follows. Distribution and infestation rate of helminths among the collected samples are, Paramphistomum spp. 68.4 per cent, Fasciola spp. 48 per cent, Eurytrema spp. 23.5 per cent, Moniezia spp. 8 per cent, Dictyocaulus spp. 3.5 per cent, Trichostrongylus spp. 12.4 per cent, and other species 26.8 per cent, respectively. In 33.4 per cent of ths cases, single infestation was seen and in 31.5 per cent, 18.0 per cent, and 14.0 per cnet mixed infestation of double, triple, and quadruple or more species were seen, respectively. Geographical analysis of infested helminths in the native cattle indicates: Among the trematoda order, Paramphistomum spp. and Fasciola spp. showed high rate of infestation throughout all districts of the country, especially Cheju island with a significant higher rate. Central district (Taejon) was higher in number of native cattle infested with Fasciola spp. than any other district of the country investigated. The rate of infestation with cestoda also showed to be higher in Cheju island than any other district of main land, but the rate of infestation with other nematoda showed no geographical difference.

BACKGROUND: Interleukin-10(IL-10) was initially discovered and isolated on the basis of its ability to suppress cytokine by Thl helper T cell. Recently, the effect of IL-10 has been reported in cultured connective tissue cells. OBJECTIVE: To further investigate the mechanisms of IL-10 on extracellular matrix(ECM) homeostasis, we evaluated the expression of type I collagen and stromelysin-1 at the transcriptional level and also observed their promoters activities. METHODS: We examined that effect of the recombinant human IL-10 on the expression of genes involved in extracelluar matrix(ECM) synthesis and remodelimg in human dermal fibroblast cultures. Quantification of collagen synthesis, Northern blot analysis, transient transfection and a chloramphenicol acetyl transferase(CAT) assay were performed. RESULTS: In studying the dose and time response effect of IL-10 on collagen synthesis, maximal reduction was seen at 1.0 ng/ml concentration and 24 hours incubation. The synthesis of type I collagen mRNA was downregulated, while stromelysin-1 gene expression was enhanced by IL-10. In the transient transfection and CAT assay, the type I collagen promoter/CAT reporter gene construct showed downregulation by IL-10, while the stromelysin-1 gene promoter activities were upregulated. CONCLUSION: It is suggested that IL-10 differently regulates the transcriptional levels of type I collagen and stromelysin-1 gene and denoting IL-10 seems to take part in the homeostasis of ECM at pretranscriptional level.

The teeth present at birth are called natal teeth, while the teeth that appear within the first thirty days following birth are called neonatal teeth. Approximately one in 2,000 to 3,500 infants experiences the eruption of teeth at birth or within the first few weeks postpartum. Many contributing factors have been suggested for the premature eruption of primary teeth. It has been suggested that upon eruption these teeth are of normal structure according to their developmental age, but after eruption, lateral movement in the cervical area leads to disturbance of the dentin and premature degeneration of Hertwig's root sheath. In most cases, they have immature, aborted structures consisting only of caps of enamel, dentin, or a combination of both. A radiograph can show the presence or absence of enamel, dentin, or root structures, as well as supernumerary teeth. These teeth may be aspirated or swallowed during feeding. Discomfort from mobile and erupting teeth often causes the infant to refuse to feed. In addition, a nursing mother's nipples may become lacerated and infected. Extraction is the indicated treatment if these neonatal teeth cause discomfort or demonstrate mobility or incomplete, immature development. Treatment decisions must be made on an individual basis from both clinical and radiographic findings. We report four cases of neonatal teeth in complete cleft lip and palate patients.
