Soft denture liners or conditioners may be valuable therapeutic materials. The life of these liners is short and varies, but it can be extended by the use of a mono-poly(polymethyl methacrylate coating material). This study determined whether coating three temporary soft denture liners with mono-poly affected the resiliency of soft liners, and evaluated the ability of mono-poly to prevent water absorption and alcohol loss from the underlying soft liners. 20x12mm cylindrical specimens of Coe-Soft, Soft-Liner, Coe-Comfort soft lining materials were made and divided into two groups of mono-poly uncoated(control) and mono-poly coated specimens. Specimens were immersed in water and compressed on an instron universal testing machine and weighted at initial, 24 hours, 1 week, 2 weeks, and 4 weeks. resiliency was determined by measuring the energy absorbed by the soft liners when stressed to a specific yield point. Mono-poly coating significantly increased the resiliency of the Soft-Liner, but had no effect on the other soft liners. Among the 3 soft liners, Soft-Liner showed the hightest resiliency and modulus of elasticity. The weight loss in Soft-Liner was the least among the 3 liners, and the weight loss in Coe-Soft was decreased by monopoly coating.

The retinoic acid and retinoid(Ro 11-1430) were alternately applied topically on forty patients with acne vulgaris. Therapeutic effects and side reactions of this regimen were compared with our previous studies of the treatment with retinoic acid alone and with retinoid alone. Compared with the treatment with retinoic acid alone, the therapsutic effect of the alternating treatment was relatively superior as indicated by the markedly reduced severity of local side reactions.

Monilethrix is a rare hereditary disorder of hair which was described by smith in 1879. The scalp hair is most frequently affected but the body or sexual hair are rarely affected. The affected hair shows periodic constrictions that break easily, so the hair could not grow more than a few millimetere long. It is thought that the node of the affected hair is normal and the thin internodal segment is deficient in hair matrix. Keratosis pilaris is generally an associated feature. We experienced a case of monilethrix with keratosis pilaris. The 4 years old male patient with monilethrix affected only scalp hair with keratosis. The family history was non-contributory.

BACKGROUND: Asthmatic patients frequently suffer cold-weather-associated respiratory symptoms. The sensitivity, specificity, accuracy and diagnostic value of isocapnic hyperventilation of cold air(IHCA) using a multistep method was investigated in patients suspected to have asthma. METHOD: One hundred and 29 adult patients who had an IHCA performed between july 1999 and December 2000, had an methacholine bronchoprovocation test because of a clinical suspicion of asthma. RESULTS: According to strict criteria, 50 were defined as asthmatics and 79 as symptomatic nonashmatics. There were no differences in age, sex and smoking state between the asthmatic and symptomatic nonasthmatic groups. There was a significant decrease in the percentage reduction in the forced expiratory volume in 1 second(FEV1) after the IHCA between the asthmatics(-10.0±6.8%) and the symptomatic nonasthmatics(-2.3±2.5%). The factors associated with a reactivity to IHCA were FEV1/FVC, FEF25-75/FVC and FEV1(% of predicted). The accuracy was highest using a 7% fall in FEV1; the sensitivity was 76% and the specificity 96%. CONCLUSION: IHCA is a specific, although not a sensitive, test for diagnosing asthma in adult patients. Furthermore, the diagnostic cut-off value of the different methods of IHCA need to be determined.

In order to study the relationship between life-style and serum lipids level in young adults, the author measured the concentration of serum total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) and investigated age, relative weight, weekly alcohol intake and daily cigarette smoking through questionnaire in 310 male workers aged 20 to 39, in Ulsan area. The results obtained were as follows: 1. In the factors being able to influence serum lipids level there was negative correlation between age and alcohol intake, and the positive corrrelation between age and relative weight, alcohol intake and relative weight, alcohol intake and smoking with the strongest correlation between alcohol intake and smoking. 2. In univariate analysis, mean total cholesterol concentration were significantly different according to age, smoking and relative weight; mean triglyceride concentration were significantly different according to relative weight only; mean HDL-C concentration were significantly different according to alcohol intake alone. 3. In non-drinkers, HDL-C concentration of smokers were significantly lower than that of nonsmokers but triglyceride concentration of smokers were significant higher. And in drinkers, total cholesterol concentration of smokers was significantly higher than that of non-smokers. 4. In multiple regression analysis, significant independent variables were relative weight, age and smoking in the total cholesterol concentration, and relative weight, age and alcohol intake in the triglyceride concentration, and alcohol intake, relative weight and smoking in the HDL-C concentration. By these independent variables, total variation in each dependent variable was explained 7.9%, 17.6% and 7.4% respectively.

This study was designed to estimate the prevalence of hepatitis C virus(HCV) infection in drug abusers. The subjects were 141 inpatients who had been admitted to a general hospital with the symptoms and signs of methamphetamine intoxication. Seroprevalence of antibody to the hepatitis C virus(anti-HCV) was 60.3%,(85/141) and it was higher in the group with increased frequency and duration of drug abuse, but such a relationship was not found in the seroprevalence of hepatitis B surface antigen(HBsAg). These findings suggested the possibility of high prevalence of HCV infection in methamphetamine abusers, and the importance of repetitive percutaneous injection in the transmission of HCV infection.

The serologic tests for syphilis including VDRL and TPHA tests were performed on generaI entertainers in Jung Ku and Young Deung Po Ku, and prostitutes including general entertainers in the Pa Ju area from January 1978 to June 1978. In the same period, direct vaginal smear with Gram stain and culture in Thayer-Martin media were carried. aut for all the general entertainers in Jung Ku and Young Deung Fa Ku as well as for the prostitutes in the Pa Ju area. The results were as follows: 1. An overall VDRL reactive rate of 5, 6 A was found among the 6, 666 general entertainers and prostitutes studied. The reactive rate of VDRL test was 5.3, in 5,289 general entertainers, and 7.6% among the 837 prostitutes in the Pa Ju area. 2. With regard to the VBRL quantitative test, the reactive rate of the group with a titration of 1: 8 or higher rvas 34.8, among the general entertainers of Young Deung Po Ku and Jung Ku. 3. The overall biologic false positive rate of VDRL test was 16.8% in the Young Deung Po Ku and Pa Ju areas using the TPHA test as the standard. 4. The positive rates of culture in Thayer-Martin media were 8.6% out of 1,387 general entertainers of Young Deung Po Ku and l.3% out of 4,352 in Jung Ku respectively, and 2.5 out of 326 prostitutes in the Pa Ju area. The findings seem to be probable that no remarkable change of the incidence of syphilitic and gonococcal infection has taken place recently among the genera. entertainers and prostitutes.
