본 연구는 우리나라 장수노인들의 식품섭취상태를 분석 평가하고 건강한 장수를 위한 식생활 지침의 설정을 위한 기초자료를 얻고자 수행되었다. 연구 대상은 경상북도 성주군에 거주하는 85세 이상 고령노인 중에서 일상 생활에 문제가 없는 224명이었으며 이들을 대상으로 반복 24시간 회상법을 이용하여 1년간 4회의 계절별 식품 섭취 조사를 실시하였으며 결과를 요약하면 다음과 같다. 계절별 식품군별 섭취량에 있어서 남자노인은 감자류의 섭취량이 여름철에 유의적으로 높고, 버섯류의 섭취량이 가을철에 유의하게 높은 것을 제외하고는 모든 식품군의 섭취량에 있어 계절별 차이가 나타나지 않았다. 여자노인의 경우 곡류, 당류, 두류, 채소류, 과일류, 조미료류, 음료 및 주류, 육류, 우유류, 어패류의 섭취량이 겨울철에 유의하게 높았으며, 종실류, 해조류, 난류의 섭취량은 계절에 따른 차이가 없었다. 조사 대상자들의 연평균 1일 총 식품 섭취량은 594.4±186.1 g이었으며 이 중에서 513.5±161.2 g(86.4%)는 식물성 식품군으로부터 섭취하였고 79.3±56.7 g(13.3%)는 동물성 식품군으로부터 섭취하였다. 섭취량이 가장 높았던 식품군은 곡류였으며그 다음이 채소류, 과일류, 어패류, 음료 및 주류, 조미료류, 두류, 육류, 우유류, 감자류 등의 순이었다. 장수 노인대상자들의 음식별 섭취빈도는 밥류에 있어서는 쌀밥의 섭취비율이 80.1~89.2%로 가장 높았으며 국과 찌개류에서는 쇠고기국, 된장국, 된장찌개의 섭취 비율이 높았다. 어육류 식품의 경우 조기구이의 섭취비율(9.4~12.7%)이 높았으며, 해조류 식품의 경우 김구이의 섭취비율(7.4~20.5%)이 높았고, 각 계절마다 계절식품의 섭취비율이 높았다. 김치류의 경우 배추김치의 섭취비율이 4계절 모두 70% 이상으로 높게 나타났다. 일품요리류는 손쉽게 조리할 수 있는 라면과 국수의 섭취비율이 높았다.<br/> 본 연구의 결과에서 경북 성주지역 장수 노인들의 계절별 식품 섭취량에 있어 겨울철의 식품 섭취량이 다른계절에 비해 유의하게 높았으며, 남자노인보다는 여자노인이 식품섭취에 계절에 의한 영향을 더욱더 많이 받는 것으로 나타났다. 또한 장수 노인들은 가공식품보다는 계절마다 제철에 생산되는 자연 식품의 섭취비율이 높았다. 전반적으로 장수노인들은 소식의 경향을 보였으며 이와 같은 소식습관과 신선한 식물성 식품들의 일상 섭취가 건강한 장수에 영향을 미쳤을 가능성도 있을 것으로 사료된다. The purpose of this study was to estimate food intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longevity. The subjects of the study were 224 elderly people of age over 85 years living in Kyungpook Sung-Ju area who have no problem in daily living. The food consumption survey was carried out seasonally by the repeated 24-hr recall method for one year. The subject group for this study was composed of 58 males and 166 females, the average age being 87 years old. Food intakes of the winter were more than any other seasons. The mean daily total food intake per capita was 594.4 g, 513.5 g (86.4%) from plant foods and 79.3 g (13.3%) from animal foods. The sequence of high intakes of food groups were cereals, vegetables, fruits, fishes, legumes and meats. Boiled white rice, beef soup, soybean paste soup, soybean paste stew, broiled yellow croaker, kimchi, ra myon and broiled noodles were consumed most frequently. In conclusion, the subjects consumed much more plants foods than animal foods and consumed more natural and seasonal foods than processed foods and also showed food habits of eating small meals. Dietary habits of eating small meals containing abundant amount of fresh plant foods might partially contribute to the longevity of the subjects.

The antigenic potential of CFA-001, cefazolin, a cephalosporin derivative produced by an enzymatic semisynthesis, was determined in Hartley guinea pigs. A battery of tests employed consisted of active systemic anaphylaxis (ASA), passive cutaneous anaphylaxis (PCA), and indirect hemagglutination test (IHA). The results were as follows: 1) In ASA, no signs attributable to anaphylaxis was observed in guinea pigs sensitized with CFA-001, whereas OVA-sensitized animals induced severe anaphylactic symptoms; 2) guinea pigs did not produce antibodies against CFA-001 when sensitized with or without Freund's complete adjuvant (FCA) in homologous PCA tests. Meanwhile, antibodies against ovalbumin (OVA) were clearly detected; 3) No CFA-001-specific hemagglutination was observed in the IHA using sera obtained from CFA-001-sensitized guinea pigs. These results suggest that CFA-001 has no antigenicity potential in guinea pigs.

<P><B>Abstract</B></P> <P>Exposure of the developing fetus and infants to toxic substances can cause serious lifelong health consequences. Several chemicals have been associated with adverse neurodevelopmental disorders in the early life stages of humans. However, most epidemiological studies have focused on a limited number of chemicals, and hence may exclude important chemicals from consideration or result in conclusions built on associations by chance. In the present study, we investigated the chemical exposure profile of the women, and associated these with the early neurodevelopmental performance of their offspring at 13–24months of age. The chemicals assessed include four phthalates, bisphenol A, three heavy metals, 19 polychlorinated biphenyls (PCBs), 19 organochlorine pesticides, and 19 polybrominated diphenyl ethers, which were measured from urine, whole blood, serum, and/or breastmilk of the pregnant or lactating women. For neurodevelopmental performance, the Bayley Scales of Infant Development-II (BSID-II), Social Maturity Scale (SMS), and Child Behavior Checklist (CBCL) were measured from a total of 140 toddlers. Among the measured chemicals, monoethyl phthalate (MEP) in maternal urine was significantly associated with early mental, psychomotor, and social development. In addition, breast milk di-ethylhexyl phthalate (DEHP) metabolite and blood lead concentrations were inversely associated with mental and psychomotor development indices, respectively. Maternal blood PCB153, heavy metals, and urinary MEP levels were also higher among the children with behavioral problems, as indicated by the CBCL range. Taken together, maternal exposure to several EDCs such as PCBs and DEHP was associated with adverse neurodevelopmental performances among the children aged 1–2years. Confirmation of these association in larger populations, as well as longer-term consequences of such exposure warrant further investigation.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Prenatal Hg, Pb, BPA, or DEP exposures were associated with neurodevelopmental delay. </LI> <LI> DEHP exposure through lactation showed negative association with mental index. </LI> <LI> Prenatal Hg, DEP, or PCB exposures showed positive associations on CBCL scores. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

<P><B>Abstract</B></P> <P>The impact of aluminum carbide (Al<SUB>4</SUB>C<SUB>3</SUB>) at the metal/silicon-carbide (SiC) interface is presented here with respect to 4H-SiC Schottky barrier diodes (SBDs). A post-annealing process at a high temperature (1000°C) has been employed for the reaction between the aluminum and the carbon. The current density of the fabricated device was measured as ~ 13.4A/cm<SUP>2</SUP> at 5V with a leakage current density of less than ~ 6.84 × 10<SUP>−9</SUP> A/cm<SUP>2</SUP> at − 5V. The thermal-activation energy (<I>E</I> <SUB> <I>A</I> </SUB> = 0.35eV) extracted from the Arrhenius plot decreased by ~ 37% via the formation of the Al<SUB>4</SUB>C<SUB>3</SUB>. According to the experiment results, the sample with the Al<SUB>4</SUB>C<SUB>3</SUB> layer yields a rectification ratio of 1.95 × 10<SUP>9</SUP> that is 33 times higher than that of the reference SBDs. The structural defects of the SiC interface may be available for the formation of the Al<SUB>4</SUB>C<SUB>3</SUB> layer.</P>

Purpose: To present the author’s experience with various treatment methods of granulomatous lobular mastitis (GLM) and to determine effective treatment methods of GLM. Methods: Fifty patients who were diagnosed with GLM were classified into five groups based on the initial treatment methods they underwent, which included observation (n = 8), antibiotics (n = 3), steroid (n = 13), drainage (n = 14), and surgical excision (n = 12). The treatment processes in each group were examined and their clinical characteristics, treatment processes, and results were analyzed respectively. Results: Success rates with each initial treatment were observation, 87.5%; antibiotics, 33.3%; steroids, 30.8%; drainage, 28.6%; and surgical excision, 91.7%. In most cases of observation, the lesions were small and the symptoms were mild. A total of 23 patients underwent surgical excision during treatment. Surgical excision showed particularly fast recovery, high success rate (90.3%) and low recurrence rate (8.7%). Conclusion: The clinical course of GLM is complex and the outcome of each treatment type are variable. Surgery may play an important role when a lesion is determined to be mass-forming or appears localized as an abscess pocket during breast examination or imaging study.

Delayed esophageal rupture due to blunt injury is not new. However, rupture due to suspected barotrauma is very rare. We describe a case of esophageal rupture in a male 24-year-old patient after diving in shallow waters. The patient was quadriplegic and could not experience the typical chest pain related to rupture and resulting mediastinitis. The rupture was discovered 4 days after emergency decompressive laminectomy and fusion for his cervical spine. The rupture was evidently caused by barotrauma and was discovered four days after admission. He underwent primary closure and pericardial flap as a life-saving procedure.
