The influence of adding iodine as a contrast substance to elevate radiation in a tumor is studied using simulation techniques of Monte-Carlo. The study is carried on a brain cancer by adopting an unsophisticated head phantom. The ionizing radiation source is an external beam of x-rays with energy range of a few tens of keV. The expected radiation dose increment due to adding the iodine is investigated by comparing the radiation in the tumor after and before adding the iodine and calculating the ratio between the two doses. Several concentrations of the contrast substance are used to quantify its impact. The change of the dose increment with the source energy is also examined. It is found that the radiation elevation in the tumor tends to saturate with increasing the iodine concentration, and for the studied domain of energies (30 keV-100 keV), the radiation dose enhancement factors (RDEF) for the different iodine concentrations (1%-9%) show peaked curves, with the peak occurring between 60 keV and 70 keV. For the highest concentration studied, 9%, the peak value is almost 7.

아토피피부염은 만성 염증성 피부질환으로 습진성병변, 피부건조 및 가려움증의 특징적 증상을 보이는 질환이다. 현재 사용되고 있는 아토피피부염 치료약제들은 오래 사용시 여러 부작용이 있어서 이를 대신할 새로운 대체 치료법의 개발이 요구되고 있다. Curcumin은 항염, 항알러지와 같은 효과를 나타내는 천연 폴리페놀(polyphenol)이며, 발광다이오드(light emitting diode, LED) 광치료는 아토피피부염과 상처치유에 효과가 있는 것으로 알려져 있다. 본 연구는 DNCB로 유도한BALB/c 마우스의 아토피피부염에서 curcumin 투여와 630 nm LED 조사를 병용하여 그 치료 효과를 높일 수 있는가를 조사하기 위해 시도하였다. 아토피피부염의 치료 효과를 조사하기 위해 modified SCORAD 지수, 조직병리학적 분석, 면역조직화학염색 및 TUNEL 검사를 사용하였다. 그 결과 curcumin 투여와 630 nm LED 조사가 각각 SCORAD 지수, 비만세포 및 탈과립세포의 수, 호산구 수, 표피세포의 증식능 및 자멸세포의 수를 의미 있게 감소시키고, 비만세포의 탈과립을 억제하여 섬유모세포에 의한 콜라겐 생성을 의미 있게 감소시켰으며, curcumin 투여와 LED 조사를 병용하였을 경우 단일 처리군에 비해 이들 수치가 의미 있게 감소하는 것을 확인하였다. 이러한 결과는 아토피피부염 치료에 curcumin 투여와 LED 조사가 각각 효과가 있음을 의미하며, 병용 치료 시 그 효과가 좀 더 향상된다는 것을 의미하는 것으로, 아토피피부염의 대체치료 전략으로 curcumin 투여와 630 nm 조사의 병용 치료를 제안한다.

We compared the clinical efficacy of LED therapy using 880 nm and 630 nm LED to test collagen accumulations in subcutaneous tissue of mouse after LED irradiation by measuring the quantity of collagen. 880 nm and 630 nm LED was irradiated on the back of ICR mouse given at $10.8J/cm^2$ followed for 30 minutes everyday for 5 weeks. Histological observation was performed by Hematoxylin & Eosin staining and Masson's Trichrome collagen staining. We also used Sircol soluble collagen assay kit for measuring the amounts of collagen in the mouse skin tissue after 1, 3, and 5 weeks post LED irradiation, respectively. Collagen generation was found at subcutaneous tissue, and the quantity of collagen in 880 nm LED group had grown more than that of 630 nm LED group at 5 weeks follow-up later. About 75% more efficacies for collagen generation were found in the group of 5th week of 880nm LED irradiation. The efficacy of 880nm LED could be more useful than 630 nm LED for synthesizing collagens in mouse subcutaneous tissue as time followed.

Purpose: The purpose of the study is to investigate the relationship between total serum bilirubin(TSB) and transcutaneous bilirubinometry(TcB) in neonates with jaundice. Method: TcB from various sites(forehead, sternum, abdomen, buttock, hand, dorsalis-pedia) was measured using a JM-102 in a total of 102 neonate, 42 female and 60 male, with the mean 37.5 gestational week and the mean 2,903 gram of birth weight, as well as TSB from capillary punctures. Result: The mean bilirubin was 11.73 in serum, 20.55 on the forehead, 17.23 on the sternum, 16.19 on the abdomen, 18.22 on the buttock, 15.83 on the hand and 15.49 on the dorsalis-pedia. The relationship between TSB and TcBs were formulated by simple regression with 0.406 < r < 0.668(p < .000). A higher relationship was revealed between TSB and TCB at the forehead in infants of full-term, ABO incompatibility, and Hb greater than 16 mg/dl(r =0.725, 0.790, and 0.717, retrospectively). Phototherapy altered the measurement of TcB per site. Conclusion: TcB on the forehead is a reliable, noninvasive and convenient measurement of TSB in normal infants(Institutions need to establish quantitative equations representing the specific relationship between TSB and TCB according to the hemodynamic problems of infants such as ABO incompatibility, or low Hb).

Purpose: The study was conducted to measure stratum corneum hydration (SCH) and pH (SCP) in high-risk newborns in the early postnatal period and to explore the features related to patterns of change in those parameters. Methods: SCH and SCP were measured on the dorsal hand in 99 hospitalized newborns during the first 14 days of life and the results were analyzed using a general linear model. Results: The mean hydration was 42.9% on day 1, which decreased to 34.6% by 2 weeks (F=15.61, p=<.001). An association was observed between SCH and prematurity (F=21.12, p<.001), as well as for their interaction (F=8.11, p<.001). The mean SCP was $6.2{\pm}0.3$ on day 1, and decreased to $5.7{\pm}0.2$ (F=95.75, p<.001), with no association with prematurity. After adjusting for birth weight, SCH was higher in newborns with vaginal delivery (F=9.07, p=.023) and who received phototherapy (F=11.81, p=.011). For SCP, only delivery type had a significant influence (F=6.40, p=.044). Conclusion: This study suggests that SCH is typically in the 30% range during the early postnatal period, and that an acid mantle on the SC surface is very unlikely to form; these findings could be applied to the nursing process for promoting skin integrity in high-risk neonates.

This study examined characteristics among 131 infants who were born at three hospitals affiliated with Catholic University. Those infants were very low birth weight infants (VLBWI ). Data were gathered through review of medical records between 1990 to 1993. The results were as follows : 1. Regarding the birth weight, 72.6％ were between 1000 gm to 1500 gm and 27.4% were below 1000gm. Of the VLBWI, 27.5% had gestational age of 29-30 weeks and 22. lof had gestational age of 26 weeks and below. The birth weight of them was significantly correlated with their gestational age. 2. Most of VLBWI had been hospitalized for more than 30 days and particulaly those who were between 1100-1400gm had been hospitalized more than 60 days. And the number of clinical problem was the most influencing factor on their discharge. 3. Of the VLBWI, 28.2% were given gavage feeding. 4. Jaundice appeared predominantly on the 3rd day after birth ,with 64.1％ of incidence rate. Of those infants developed jaundice, 92.9% received phototherapy 5. The most common problem after birth was respiratory conditions. And oxygen therapy was administered for 93.9% of the VLBWI while they were in the hospital.

Objective : Subcorneal pustular dermatosis is a rare, chronic neutrophilic dermatoses that was first described in 1956. The eruption is characterized by flaccid pustules grouped in a circinate pattern on normal or erythematous skin. We treated a case of subcorneal pustular dermatosis in one patient; there have been no former reports of this disease treated by oriental medicine. We present this case because we considered it to be useful as a possible Oriental medicine treatment for subcorneal pustular dermatosis, and something that canbe used for further study of neutrophilic dermatoses. Method : We used herbal medication, acupuncture, herbal wet dressing, herbal ointment, cupping therapy and phototherapy during treatment. We assessed symptoms during treatment and also carried out blood tests through out. Result : We observed and treated a case of subcorneal pustular dermatosis patient and after treatment the patient's objective and subjective symptoms showed noticeable improvement. Conclusion : We suggest that subcorneal pustualr dermatosis can be treated by Oriental medicine therapy effectively. We expect these study results will help provide useful evidence of Oriental medicine as an effective treatment for subcorneal pustualr dermatosis.
