We investigated the quality characteristics of cookies prepared after addition of various concentrations of used coffee grounds (0%, 1%, 3%, and 5%, all w/w) as a substitute for flour. As coffee grounds concentration rose, decrease in the pH of cookie dough was evident. In terms the water-holding capacity of dough, cookies prepared 3% (w/w) coffee grounds yielded the highest value. With an increase in coffee grounds concentration, the color a value rose, but the L and b values fell. The gelatinization temperature became higher, but both peak viscosity and 15 min-height values declined. The spread and loss ratios decreased but the leavening rate rose significantly with elevation of coffee grounds concentration. The hardness of cookies rose but slightly, as coffee grounds concentration rose. Upon sensory evaluation of all of appearance, flavor, and overall preference, cookies prepared with addition of used coffee grounds were superior to those without grounds, whereas those prepared using 1%-3%(w/w) coffee grounds showed the highest overall acceptability. Thus cookies made using coffee grounds can be economically competitive. In addition, the ingredients of coffee powder and used coffee grounds were shown to be very similar, except that coffee grounds contain 15-fold less caffeine than dose coffee powder. As health concerns are popular today, the use of coffee grounds to manufacture processed food may be acceptable.

밤 가공공장에서 폐기되고 있는 밤의 귀피를 항산화 기능성 자원으로 활용하고자, 밤 귀피의 methanol 추출물 및 용매획분을 benzoic acid 수산화법으로 hydroxyl radical 소거능과 ferric thiocyanate법으로 과산화물생성 억제능을 시험하였다. 대부분의 획분에서 항산화성을 보였으며 특히 ethyl acetate 획분에서 BHA나 α-tocopherol과 거의 유사한 강한 hydroxyl radical 소거능과 지질과산화물생성 억제능을 보였다. Ethyl acetate 획분으로부터 항산화성 물질을 분리하기 위하여 Sephadex LH-20 column chromatography 및 prep HPLC를 행하여 단일 물질로 정제하였다. 분리, 정제된 물질을 ¹H-NMR과 ¹³C-NMR로 구조 분석한 결과 gallic acid로 동정하였다. 페놀산을 GC로 분석한 결과 밤 귀피의 주요 페놀산으로 ellagic acid(172.22 mg%)와 gallic acid(107.39 mg%)가 확인되었다. To enhance the utilization of chestnut husk discarded in the processing company, antioxidative activities and compounds were investigated. Antioxidative activities of solvent fractions from chestnut husk were examined by benzoic acid hydroxylation method, ferric thiocyanate method and DPPH test. Ethyl acetate fraction showed strong antioxidative activities comparable to BHA. Active compounds were isolated and purified from ethyl acetate fraction by Sephadex LH-20 column chromatography and preparative HPLC. A major active compound, gallic acid was identified by ¹H and ¹³C-NMR. The phenolic acid contents was analyzed by GC and ellagic acid (172.22 mg%) and gallic acid (107.39 mg%) were major phenolic acid of chestnut husk.

Moyamoya disease is a rare progressive cerebrovascular disorder caused by blocked arteries at the base of the brain in an area called the basal ganglia. The etiology and pathogenesis are unknown Clinically, this disease is found with a higher incidence in young female, but there are few cases of moyamoya disease in pregnancy. The disease primarily affects children, but it can also occur in adults. in children. The first symptom of moyamoya disease is often stroke, or recurrent transient ischemic attack, frequently accompanied by muscular weakness or paralysis affecting one side of the body, or seizures. Adults most often experience a hemorrhagic stroke due to recurring blood clots in the affected brain vessels. The diagnosis of moyamoya disease is made on the basis of angiographic findings and threatment of Moyamoya disease is surgery, or conservative management. We report a case of moyamoya disease that presented as intracerebral hemorrhage and intraventricular hemorrhage during pregnancy complicating severe preeclampsia.

목적 : 최근 쌍태임신의 임상양상적 특징과 그 결과를 알아보고자 함. 방법 : 1990년부터 1999년까지 포항성모병원 산부인과에 입원하여 분만된 18,333예중 쌍태분만 149예 산모의 임상기록부를 관찰, 분석하였다. 결과 : 쌍태분만의 발생빈도는 1:123이었다. 총 쌍태임신에 대한 보조생식술에의한 쌍태임신의 비율은 1990년부터 1994년까지 5.3%에서 1995년부터 1999년까지 25.4%로 증가하였다. 임산부 연령은 26-30세군이 41.6%로 가장 많았고 이들의 평균 연령은 27.5±4.1세였다. 또한 초산부가 전체의 71.8%였다. 임신주수는 37-38주군이 43.6%로 가장 많았고 평균 임신주수는 35주 5일 이었다. 태위로는 두위-두위군이 42.3%로 가장 많았다. 분만방법에서는 제왕절개분만이 전체의 77.2%였고 이들의 가장 많은 적응증은 선택적 제왕절개분만이었다. 신생아의 평균체중은 2,315±610g 이었다. 신생아 Apgar점수는 제1아에서가 제2아 보다 성적이 좋았다. 태반의 형태는 이중양막 및 단일융모막이 54.4%로 가장 많았다. 성별에서는 둘다 남성인 예가 44.9%로 가장 많았다. 산모합병증에서는 빈혈이 41.6%로 가장 많았다. 주산기 사망율은 1,000명당 97명이었으며 이의 가장 많은 원인은 조산(64.0%)이었다. 쌍태분만으로 인한 모체사망은 없었다.결론 : 최근 쌍태임신의 빈도는 증가하고 있지만 쌍태임신은 단태임신보다 많은 산과적 합병증과 높은 주산기 사망율을 나타내고 있다. 따라서 이를 줄이기 위한 더 많은 연구가 필요하다. Objective : To evaluate the clinical aspects of twin pregnancy and its results Methods : We reviewed the medical records of the 149 cases of twin births among 18,333 deliveries, from Jan. 1, 1990 to Dec. 31, 1999 at Pohang St. Mary's Hospital. Results : The incidence of twin births was one in 123 births. The rate of twin pregnancies by assisted reproduction technique was increased from 5.3% between 1990 and 1994 to 25.4% between 1995 and 1999. The predominant age group was 26-30(41.6%) and mean age was 27.5±4.1 years old. According to parity, nullipara(71.8%) was the most frequent. The predominant gestational age of twin births was 37-38 weeks(43.6%) and mean gestational weeks of twin births was 35 weeks and 5 days. The cephalic-cephalic combination(42.3%) was predominant presentation. The most common mode of twin delivery was cesarean section(77.2%) and its main indication was elective. The mean birth weights of twins was 2,315±610 grams. Low one minute Apgar scores occured more often in second twins than in first ones. The most common type of placental membrane was diamniotic-monochorionic(54.4%). Both male group(44.9%) was predominant. The most frequent maternal complication during pregnancy was anemia(41.6%). The perinatal mortality rate was 97 per 1000 newborns and its main cause was prematurity(64.0%). Maternal deaths were not encountered. Conclusion : Recently, although the incidence of twin pregnancy has been increased, it has greater risks of obstetrical complications and higher perinatal mortality than singleton pregnancy. Therefore, further studies are needed for effective management of twin pregnancy.

Separation of symphysis pubis during vaginal delivery is rare condition with incidence ranging from 1/500 to 1/30000 deliveries. The injury is caused by fetal head exerting pressure on pelvic ligaments that have been relaxed by progesterone and relaxin. The separation might be associated with considerable pain, swelling and tenderness over the pubic area. Diagnosis is based on clinical findings and X-ray findings. The condition is treated conservatively with bed rest, analgesics and physical therapy. Prognosis is exellent. We experienced 3cases of separation of symphysis pubis during vaginal delivery and report these cases with a brief review of literature.
