1.Studies on Liquefaction of Human Semen.
Korean Journal of Urology 1975;16(3):133-139
The human semen ejaculated in a form of liquid state, coagulates immediately after ejaculation, and then liquefies again. However, the mechanisms of neither coagulation and liquefaction of semen have not been explained clearly so far, and very limited numbers of report are available, although the spermatology and andrology made rapid progress. This clinical study has been undertaken to investigate the liquefaction phenomena and practicability of the results might be applied to fertility and infertility problems. As a preliminary study, in this report the liquefaction time of various semen groups is measured and analyzed. The following results are obtained: 1. An average liquefaction time of semen of a total of 60 subjects:25 minutes. 2. An average liquefaction time of semen according to sperm count: I) Normospermia group(20 cases) :34 minutes. 2) Oligospermia group(20 cases) :21 minutes. 3) Azoospermia group(20 cases) :20 minutes. An average liquefaction time of semen according to abstinence period: I) Less than 3 days group(20 cases) :22 minutes. 2) More then 5 days group(30 cases) :28 minutes. In conclusion: I. The liquefaction time of semen of the normospermia group is longer than oligospermia group or azoosermia group. 2. The liquefaction time of semen may not be greatly influenced by the various factors such as abstinence period. semen volume, semen pH. age of the subjects and so on. In routine semen analyses, it is recommended to begin the analysis at least 25 minutes after the ejaculation. 4. Further studies are required in conjunction with practical application of liquefaction mechanism in infertility and fertility control.

2.A survey of the Types of Burns in Children and Mother's Preventive Attitudes to, and Knowledge of Burns.
Korean Journal of Child Health Nursing 1998;4(1):97-104
Burns is children result in the loss of precious life, or if the child survives, in much suffering from physical, emotional, social, and economic problems. These burn accidents to children happen in the bustle of family life and frequently without any warning. With this background information, this study was designed to identity types of burns in children and mother's attitudes towards, and knowledge of burn prevention, in order, to not only, in still a safety consciousness regarding the seriousness of burn accidents and the strengthening prevention, but also as basic data towards the development of an educational program aimed at prevention. From May 1 to May 25 in 1997, data were collected from the mothers of children attending five day care centers and kindergartens located in Seoul, which had been selected for the study. The tools used for the study, which were developed by the researchers, surveyed the type of burns suffered by children, mother's knowledge of burns and attitudes toward burn accidents. The data were analyzed through real numbers percentages and analysis was done using SPSS computer programs. The results of the study show that the most frequent type of burn accidents were those caused by hot water(55.4%) and these were frequently related to everyday habits that easily lead to danger. Further, the first aid treatment following a burn was weak. The majority of the mothers had not instructed their children on who to contact in the cape of a fire, first aid for burns, or how to take escape in the case of a fire. This left the children in a defenseless position in case of a fire. The mothers showed a lack knowledge, on what to do when a blaze is discovered, how to put out a fire, first aid for burns, escaping from a fire and appropriate water temperature, in that 50% of the time they answered incorrectly. From this study a prevention program, HIPP(Home Injury Prevention Program) could be developed that includes fire prevention habits and first aid for burns. This program can be used with kindergarten and elementary school children for group education fire prevention and can be used as a foundation for construction of a system of facilities and equipment to prevent fires and also prevent injury from fires.

3.A Study on Dietary Intakes and Nutritional Status in College Women Smokers - II. Assessment of Nutritional Status for Antioxidant Vitamins.
Korean Journal of Community Nutrition 1997;2(2):159-168
This study was done to compare the nutritional status of antioxidant vitamins between college women smokers and nonsmokers. Dietary intakes and serum levels of antioxidant vitamins were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Dietary intakes of vitamin A and C were determined by a quick and convenient dietary intake method. Serum vitamin C level was measured by 2,4-dinitrophenylhydrazine method and serum levels of vitamin A and E were measured by HPLC. The mean A intake of nonsmokers and smokers was 504.3 microgram R.E./day and 450. 4 microgram R.E./day and the mean vitamic C intake of nonsmokers and smokers was 51.6mg/day and 50.2mg/day, reapectively. There was no difference in the dietary intakes of antioxidant vitamins between smokers and nonsmokers. The serum vitamin A level, 0.71mg/1 in nonsmokers was not significantly different from that of 0.74mg/1 in smokers. However, the serum vitamin C level, 7.94mg/1 in smokers was 15% lower(p<0.05) than that of 9.30mg/1 in nonsmokers. The serum vitamin E level, 18.15mg/1 in smoders was also 34% lower(p<0.05) than that of 27.58mg/1 in nonsmokers. There was no significant correlation between dietary intakes and serum levels of vitamin A and C for both smokers and nonsmokers. These results suggest that cigarette smokers need more dietary intakes of vitamin C and E than do nonsmokers to reach the same serum level.

4.Study on Peripheral T - Cell Pepulation in Parients with Leprosy.
Korean Journal of Dermatology 1978;16(1):3-7
It is generally believed that the defense against mycobacterium leprae is largely mediated through cell-mediated immunity(CMI) and several investigators have reported a defective CMI in patients with leprosy. especially the lepromatous from. This study was undertaken to ennumerate the peripheral T-cell population in leprosy patients for evaluation of one aspect of its immune status. Fiftu-two patients with leprosy(26 tuberculoid, 17 active lepromatous, 9 inactive lepromatous) entered in this study. All the patients are under regular antileprosy chemotherapy for varing periods(10 months to 14 years). Peripheral blood T0lymphocytes were enumerated by the E-rosette technique and compared with normal healthy control. The results were as follows: The mean T-cell percentage in peripheral blood was 50.6% in 17 active lepromatous leprosy patients, 62.2% in 9 inactive lepromatous leprosy patients, 67.7% in 26 tuberculoid patients and 69.5% in 17 normal healthy controls, There was marked decrease in the peripheral T-cell ratio in active lepromatous group (p<0,005) and less marked decrease in inactive lepromatous group (0.01.

Korean Journal of Dermatology 1978;16(4):331-336
Nickel sensitivity is the most common cause of allergic metal dermatitides,, particularly in women. Women are uaually sensitized. by the objects wom close to the skin ('e.g. earring, necklace fasther, watch, suspenders, brassiere clips, etc.), and men are by occupational exposures (e.g. plating or printing industries, tools, etc.). Nickel dermatitis is frequently developed on the sites where seems to have been directly contact witb nickel substance, but secondary eruptions may develop on the areas where seems to have not been directly exposed to nickel, so that nickel dermatitie is sometimea misdiagnosed as atopic dermatitis, nummular eczema, stasis dermatitis, or other dermatitides. The authora prcsent two cases of nickel dermatitis confirmed by patch test with 2. 5% nickel sulfafte; first case-a 22 years old female who has erythemat,ous maculopapular patches on her ears, around neck, left wriat, elbows, and abdomen; second case tkat was previously misdiagnosed as mummular eczema-a 18 years old female who has large oozing and crusted patches on both lateral aspects of her right thigh and back, The authors reviewed the incidence of nickel sensitivity during past years in korea and the clinical aspect of distribution of nickel dermatitis.

Korean Journal of Dermatology 1975;13(4):263-270
Warts are benign turnors caused by oncogenic human papovavirus which has been clearly identified on electronmicroscopy, although repeated atternpts at culture have not been successful. Various therapeutic modalities have been tried for the treatment of warts, however thete is no saisfactory method and the clinical course as well as the prognosis is always variable. Recently several authors have reported successful therapeutic results in the treatment of warts by DNCB sensitization method based on the findings that warts are often regressing spontaneously and that the spontaneous regression seems to depend on host's ability to mount an immune response against the wert virus. The present study was undertaken to evaluate the DNCB sensitization method for possible routine use in the treatment of warts. Fifteen cases including five verruca vulgaris and ten verruca plana juvenilis patients were sensitized with 1000ug of DNCB in acetone solution on either side of their inner forearms. Seven or ten days after sensitization, several warts, which were unintentionally selected, were challenged with 0.05 to 0.1ml of weaker DNCB solution(50ug-25ug/0.1ml)at weekly interval. Four patients with verruca vulgaris and three patients with verruca plana juvenilis did not return after 1 to 4 times of challenge, however six out of these 7 patients showed a slight decrease in size and number of the warts. One patient with verruca plana juvenilis developed marked irritative and delayed cutaneous hypersensitivity reaction to the 3 times of challenge, so that this patient was excluded from further study. The remaining 7 patients consisted of I verruca vulgaris and 6 verruca plana juvenilis patients showed complete disappearance of all warts including those which were never challenged, after 1 to 13 times of DNCB challenge application. The authors reviewed the possible therapeutic mechanism of DNCB sensitization in the wart patients, the possible advantage and disadvantage of this method and concluded that this method can be cautiously used in seleted patients with warts whose response to the conventional treatment methods are poor.

Senile sebaceous hyperplasia refers to a benign enlargement of a normal sebaceous unit which is not uncommon in the old age group, and is characterized clinically by single or multiple small cream to yellowish round papules developed on the face, chiefly on the forehead and cheeks. A case of florid senile sebaceous hyperplasia developed in a 81-year-old man was presented. Because this disorder is one of the geriatric dermatoses and the average life span of our people is remarkably lengthened in recent years, we believe dermatologists should pay more attention to this kind of dermatosis.
