1.A Study of Anctiviy with CAstsnea Crenata Flos.
Korean Journal of Dermatology 1976;14(2):91-95
There are many herbs used in the treatment of dermatophytosis as home medicine and Castanea crenata Flos (C.C.F.) is one of that used in Kyung gi-do district. With that regard we tried to examine in vitro antifungal activity of the C.C.F. with its water extract and alcohol extract as the test materials. Until now many authors have studied the antifungal activity with several plant extracts, as like the alcohol extracts of Zanthoxylum piperatum Fructus and Berberis Korea palibin or Fennel oil, and reported that these plant extrscts or essential oiI have good antifungal activities in vitro and in vivo. On that they said that the principal fractions those have strong fungistatic activity were all alikely the fatty acids chemically similar with the well known undecylenic acid. At this in vitro experiment the extracts of C.C.F. were diluted. serially in the Sabourauds dextrose agar and certain portions of fungi (the strains of Trichophyton (Tr.) mentagrophytes and Tr. rubrum) were transplanted into each medium containing different concentrations of test materials then observed its growth for 2 weeks at room temperature. After that we measured the sizes of colony grown in various conditions and compired with that of the normal medium to determine the fungistatic effectiveness. As the result, in the view of the colony sizes, Tr. mentagrophytes and Tr. rubrum equally revealed marked inhibition of its growth only in the media with water extract over the concentration of 10mg/ml in the mediurn, and the critical fungistatic dilution was 20 mg/ml. We could not identified the principal fraction in the water extract of C.C.F.which exhibited antifungal activity. In the comparison of the critical fungistatic dilution with the alcohol extract of Zanthoxylum piperaturn Fructus and Fennel oil, water extract of C.C.F. required tenfold higher concentration for the same effect. However in regarding the utilizing habits of C.C.F. in horne medicine, as topical wet dressing with water boiled solution, we might expect its effect practically. iVow there are problems to be investigated about the chemical natures and physical properties of the C.C.F. and for the antifungal fractions of it, in addition further in vivo study we thought would be interesting.

3.Two Cases of Weber-Christian Disease.

Two cases of Weber-Christian disease are reported. This very rare disease, we had two another reports of case sincc last ten years in The Korean Journal of Dermatology. In our cases both patients are seventeen years old girls and have the histories of remissions and exacerbations for two to three years. The skin lesions of subcutaneous nodules are scattered on the trunk, extremities and even to the hand dorsurns, with the atrophic depressions. Histologic features are typical with faormy histiocytes in the subcutaneous fat tissue. On tne treatments these patients are given oral corticosteroid, antihistaminics and salicylate with some improvments.

Korean Journal of Dermatology 1979;17(3):215-219
Finger print patterns were studied in a series of 99 male schizophrenics who met with the diagnostic criterias of International Pilot Study of schizophrenia except items associated with chronicity in exclusion criteria, As controls, the autbors used 400 Korean men who were free of congenital, dermatological, neurological and psychiatric disorders, The frequency distribution of the finger print patterns in the 99 s'chizophrenics were whorls 52.45%, loops 49.09% and arches 3.46%. and that of controls were vrhorls 49.65%, loops 46.38% and arches 3.97%, The diffeence in pattern frequency was statistically significant (P<0.05). However, the striking differences were found in the frequency of the ridge dissociation. The observed frequency was very significantly high (p<0.005) in the schizophrenics (16.16%) compared to controls (6.25%). This findings supported the rcport of the Raphael (18%) but the frequency of our controls(6.25%) were not matched with previous study of Abel (The frequency for his 4,000 control was negative. No plausible explanation is not found for the extraordinary high frequency of ridge clissociat,ions in the controls of tbis study. Although rnore extensive investigation in needed for the explanation of significantly high frequency of ridge dissociation in thes chizophrenics, the findings of the present study give us another evidence of the constitutional factors in schizophrenics.

Korean Journal of Physical Anthropology 1990;3(2):119-129
The primitive erythroblasts in 21 cases of embryonic hearts from 4 to 9 weeks of gestation were studied with a light microscope. The nuclear diameter, the motosis, and the loss of nuclei of the primitive erythoblasts were analyzed quantitatively. The results obtained were as follows. 1. At 4 weeks of gestation, the blood cells consisted of proerythroblasts, along with basophilic polychromatophilic primitive erythroblasts. The nuclear diameter ranged from 3.20 µm to 9.20 µm, but the main range was from 4.20 µm to 6.00 µm. It was revealed that 9.50% had diameter of more than 6 µm. 2. At the fist half of the 7 week gestation when hepatic hemopoiesis developed, the blood cells consisted of basophilic, polychromatophilic, and eosinophilic erythroblasts. Cells of more than 6 µm in nuclear diameter were about 1.10% and thereafter gradually disappeared. The range of the nuclear diameters was from 2.60 µm to 7.00 µm, while a range from 3.40 µm to 5.20 µm wqs the main. The proportion of cells less than 4 µm in nuclear diameter was 39.58% and thereafter rapidly increased. 3. From the second half of 7 weeks to 9 weeks of gestation, the erythrocytes originating from hepatic hemopoiesis increasingly replaced the circulating primitive erythroblasts, which became mature during this time. The erythrocytes showed 72.88% at 9 weeks of gestation. The proportions of cells less than 4 µm in nuclear diameter in the first and second haIves of 8 weeks and 9 weeks were 52.73%, 80.02%, and 89.09%, which represented the rapid destruction of nuclei. 4. Mitosis in the primitive erythroblasts occurred principally up to the early 6th weeks, and very weakly at 8 weeks. 5. As the crown-rump length increased, the average nuclear diameter decreased very significantly (P<0.01, y=-0.2811X + 0.3171). The results suggest that distrilbution of the nuclear diameter, the maturity, the rate of nuclear loss, and the mitotic figure offer credible data for estimating embryonic age.
