1.An Analysis of Chrome in Cements and Bleaching Detergents.
Korean Journal of Dermatology 1990;28(1):11-15
The chrome content of 8 Korean cements and 11 Korean bleaching detrgents was analyzed by the qualitative DPC method and the quantitative atomic absorption spectrophotometry and UV-visible spectrophotometry. In cements, there was no detectable chrome in 1 sample and the range of chrome content in other 7 samples was 1.32 5.29ppm. The qualitative result was welJ. correlated with the quantitative result. In bleaching detergents, there was no detectable chrome in 4 samples and the range of chrome content in other 7 samples was 0.0329 0.362ppm. However, the qualitative result was not correlated with the quantitative result.

In August 2001 we began to use WELPAS (a benzalkonium chloride solution) as part of our cost-containment drive, replacing self-made glycerol-added ethanol, which had been used for a long time to prevent nosocomial infections. Since then, blackish stains have become particularly noticeable here and there on the floorboards of the passageways in the hospital wards. The newly adopted quick-drying hand disinfectant was suspected as the culprit. To find the real cause of the dirt, we built a hallway similar to the real passageway for experiment. The disinfectant agents used were WELPAS, WELLUP (chlorhexidine gluconate), HIBISOFT (chlorhexidine gluconate), medicinal ethanol, cationic detergent solution, HIBITANE solution (chlorhexidine hydrochioride) and glycerol solution. These agents and distilled water were dropped on a limited area of the floor respectively for comparison of the degrees of dirt. The cationic detergent solution and WELPAS containing cationic detergent left blackish stains that were hardest to remove. From this finding, it was inferred that the cationic detergent solution was responsible for the dirt on the floor. So we decided to switch to a quick-drying hand disinfectant which does not contain cationic detergents. After considering economic benefit, we chose WELLUP which contains medicinal alcohol plus chlorhexidine gluconate and put it into actual use in October 2003. Since then, the hospitall floors have become unmistakalbly clean.

BACKGROUND: It is important to avoid the direct contact with water of detergents as possible for the treatment and prevention of hand eczema. OBJECTIVE: The purpose of this study is to evaluate the protective effect of skin protector, Marly skin on housewifes eczema, METHODS: The patients with hand eczema apply skin protector, Maly skin, four times a day on their both hands. They are evaluated with the scores of subjective symptor is(itch, dryness, smarting) and objective signs(erythema, scaling, fissures), and skin replica which are taken from the specified site are analysed by using an image analyser and, scanning electron micrascipe. RESULTS: 4 weeks after application of skin protector, there are statstically significant decrease of total clinical symptom scores. Scanning electron microscopic findings of the skin replicas show marked changes between the beginning and the end of the study. On quantive image analysis of the skin replicas, the length of fissure is a little decreased and the depth of rrows is slightly increased than before application of skin protector, but these are not statistically significant. CONCLUSION: Skin protector, Marly skin, has a protective effect on the development of hand eczema.

6.Detection of formaldehyde in textiles.
Korean Journal of Dermatology 1991;29(2):155-158
Formaldehyde is contained in various everyday products such as shampoos, detergents, leathers and papers, and is thought to be one of the important couses of clothing related contact dermatitis(ACD). The results about the minimum sensitizing concentrations of formaldehyde were different, and the concentration of 30 pg per gram of textiles was the least one. We measured the quantity of formaldehyde in 16 different types of textiles which are widely used in Korea to investigate whether the textiles contain an enough amount of formaldehyde to induce ACD and washing can reduce the amount of it. The results were as follows : 1. The quantity of formaldehyde ranged from 3 to 1246 pg per gram of textiles. 2. Three types textiles contained more than 100pg of formaldehyde per gram of textiles and 6 between 50 pg and 100pg. 3. 1.00% cotton, ramie and rayon contained the highest content of formaldehyde per gram fabric. 4. After washing, the average quantity of formaldehyde decreased to 60% of that, of pre-wash measure.

Oral sodium phosphate is known to be safe and it is widely used as a colon cleansing agent for colonoscopy. Yet several complicated cases with the development of electrolyte imbalance have been reported. We report here on 2 interesting cases: after administration of oral sodium phosphate, one patient presented with hyponatremia (Na, 122 mEq/L) with seizure and the other patient presented with hyponatremia (Na, 120 mEq/L) with a confused mentality. Brain imaging and electroencephalography showed no evidence of other causes for the seizure and mental change. We report here on two cases of hyponatremia with neurologic side effects, and this was all caused by oral sodium phosphate. We also include a review of the relevant literature.

BACKGROUND: Although venous lake is asymptomatic, treatment is usually performed for cosmetic purposes or to prevent bleeding after trauma. The treatment is diverse and includes surgical excision, compression and cryotherapy. Above all, sclerotherapy is a useful and effective procedure for the treatment of venous lake on the lip. OBJECTIVE: This study was undertaken to assess the effectiveness and complications of the sclerotherapy of venous lake on the lip. METHODS: Fifteen lesions from eleven patients with venous lake on the lip were treated with sclerotherapy using sodium tetradecyl sulfate, detergent sclerosant. According to the size of lesions, the volume of infused solution was varied and the effectiveness of treatment was evaluated after four weeks. RESULTS: After a single treatment, fourteen of the fifteen lesions(93.3%) were cleared completely. The remaining lesion was treated one additional time. There were no reported complications during treatment. CONCLUSION: Sclerotherapy is highly effective and safe for the treatment of venous lake on the lip and may be a promising treatment option.

In order to prevent cross-infection, the sterilization of used and/or contaminated anesthetic- apparatus is still a difficult problem in clinical practice, particularly, following anesthesia for known advanced pulmonary tuberculosis cases. Therefore the antibacterisl activities of, an amphoteric detergent, Dodecyl diaminoethyl glycin hydrochloride (Hygien 51) were tested in vitro as a disinfectant against mycobacteria (M. tuberculosis H37 Rv, M. bovis, M. avium, M. tuberculosis H37 Ra, M. phlei, B.C.G.) The antimycobacterial activity tests were performed according to the modified Kolmer method. The testing organisms were cultured in Dubos broth at 37 degrees C, and the detergent, Hygien 51, was: diluted with sterile distilled water to 1,3,5 and 10%. One half milliliter of culture was pipetted into each tube containing 4.5 ml of diluted detergent, and at intervals of 3, 15, 30, 60, 120, 180 and 240 minutes, a 4mm loopful of the material was removed from each tube, and transferred to Ogawa media. The tests were carried out at two different temperatures, 20 degrees C and 50 degrees C. The subcultures were incubated at 37 degrees C for more than 8 weeks. The results were obtained as follows: 1) At room temperature (20 degrees C), all mycobateria, except M. bovis, were destroyed by treatment- with 10% solution of the detergent for more than 60 minutes. M. bovis was relatively sensitive to the detergent, and was killed by 5% solution for 30 min. and 10% for 15 min., but M. avium. was very resistant, and was not killed by 10% solution for 240 min. 2) By treatment with the detergent at 50 degrees C, the antimycobacterial activities of the detergent were highly increased. All mycobacteria were destroyed by 1% solution for 180 min, and by 10% for less than 30 min at 50 degrees C. In the comparison of the antibacterial activities against mycobacteria and other bacteria, it shows that mycobacteria are generally more resistant to the detergent, Hygien 51.
