N/A Background: Wound model is important for the development of dressing materials in dermatologic practice, Most of the wound healing models are not standardized, individualized ones for each special situation. Objectives: The purpose of our study is to establish a standardized wound model for evaluating the efficiency of wound healing of dressing material and the effect of epidermal growth factor(EGF) on artificially induced wounds. Methods: Using ultrapulse CO₂ laser and rats, we calibrates the most effective level of energy, frequency, and pulse duration for a wound model of upper dermis. Then, we evaluated the effect of various dressing materials such as vaseline gauze, collagen sponge, collagen sponge containing EGF and hydrogel on wound healing. Results: We obtained relatively even and uniformed wound models of upper dermal level with the setting of ultrapulse CO₂ 1aser; continuous mode, 800watt, frequency of 100Hz, and pulse duration of 0.3ms. Wounds applied with collagen sponge containing EGF showed relatively accelerated wound healing, but wounds with hydrogel or collagen sponge only showed delayed healing of wounds Conclusion: Ultra CO₂ laser could make a wound model of uniform depth level and could be used as a tool for making standardized wound models.

일부 수원지역 임신부들의 임신적 비만도에 따른 임신후반기 식행동 분석
남희정,임영숙,황의수,박혜련,정계옥 명지대학교 자연과학연구소 2001 자연과학논문집 Vol.20 No.-
이 연구는 임신전 비만도와 임신후반기의 식행동과의 관련성을 분석하여 비만 임산부의 올바른 영양관리를 위한 교육자료를 수집하고자 하는 목적으로 시도되었다. 임신전 비만도는 임신전의 체중과 키를 이용한 BMI값으로 결정하였고 입덧이 지난 23-26주 사이에 직접면접에 의한 설문조사를 실시하였으며 일일식이섭취를 24시간 회상법으로 조사하여 비만도와의 관련성을 분석하였다. 전체 조사대상 임신부들은 일일 평균 영양소 섭취량을 보면 인(mg) ㆍ 비타민A(RE) ㆍ 비타민 C(mg)는 권장량의 100% 이상 섭취하였으나 열량을 비롯하여 단백질, 칼슘, 철분, 비타민 B1, 비타민 B2, 나이아신은 권장량보다 훨씬 적게 섭취한 것으로 나타났다. 3대 영양소의 섭취 열량비율은 분석한 결과 수척군은 한국인 영양권장량에서 권장하는 3대 영양소 열량비율을 보였으나 비만군은 지질에서 얻는 열량이 상대적으로 높게 나타났으며 유의적으로 당질 섭취가 적었다. 비만군이 수척군과 정상군보다 육류 섭취시 지방을 제거하는 경향을 보였으며 식사속도는 비만할수록 빠른 경향과 결식율도 높았다. 또한 비만군에서 신생아 출생체중도 유의하게 높았으나 비만할수록 임신기간 중 체중증가량은 유의하게 적게 증가한 것으로 분석되었다. 콜레스테롤과 섬유소, 비타민 A 섭취량도 비만군에서 유의적으로 적었다. This study investigated the pre-pregnancy BMI related with dietary behavior. It's propose is to find solution of dietary methods to improve the obesity of pregnanct women. All the subjects were 78 cases in the pregnant had not any diseases and were 20∼40 years. The survey method was investigated with structured questionnaire and 24 hour recall method used with the Food Model. 24 hour recall method was investigated of only one day of 23-26 weeks the first visited after decreased in hyperemesis because the intake of meals is to normal in post-pregnancy. 24 hour recall data were analyzed to using the Can-Pro software. Height of pregnant women were measured in 23-26 weeks and weight of them were measured at visited in the hospital. BMI (Body Mass Index) was calculated to weight of pre-pregnancy. Dietary habits and attitudes were included overeating, Eating speed, snack, intake of animal fats, intake of carbonated beverages, preference of cooking methods, preference of sugar foods, preference of sodium foods, preference of spice foods and preference of fatty foods. Women history was included the number of total pregnancy. The questionnaire of physical and psychic stress were investigated using national health survey of the Ministry of Health and Social Affairs. As a result of this study is following. It was analyzed to BMI of pre-pregnancy related with intake of nutrients. There were under weight group correctly intake of calorie ratios of the three macro nutrients in Recommend Dietary Allowances for Korean, but over weight group were the highest intake of calorie ratios of fat than other groups. Also they tend to remove animal fat than others were. Eating speed was the fastest in over weight groups, besides neonatal weights increased significantly in over weight groups. But weight gains were the lowest in over weight groups. In all the subjects, intake ratios of phosporus (mg), vitamin A (RE), vitamin C (mg) was above a hundred percent of the recommend allowances, but calorie, protein, calcium, iron, vitamin B1, vitamin B2, and niacin was very below of the recommend daily allowance.

Aspiration can generate postoperative pulmonary morbidity of varing severity, depending on the type and volume of the aspirate. Epidural anesthesia can lead to local anesthetic systemic toxicity with mental change, followed by respiratory depression and abdominal and intercostal muscle weakness depressing the ability of the patient to cough and clear the airway. The authors experienced a case of pulmonary aspiration with systemic toxicity after epidural anesthesia for cesarean section. The chest X-ray showed alveolar consolidation at left lower lung field and arterial blood gases showed that PaO_2 decreased. The exact causes of mental change and respiratory depression were unknown, but we suspected it lidocaine induced systemic toxicity due to vascular absorption, When airway reflexes are ineffective during face mask ventilation of the lungs, aspiration of clear oral secretions can generate small airway obstruction.
