The purpose of this study was to investigate the quality characteristics of sponge cake with broccoli (Brassica oleracea var. italica Plenck) powder. Broccoli powder was mixed with wheat flour at various ratio (3, 5, 7, 9%, w/w) for physical and sensory evaluations. The specific gravity of bread dough increased with added broccoli powder. The moisture of the sponge cakes with added broccoli powder was higher than that of control. In the crumb color values, lightness (L) and redness (a) decreased upon broccoli powder addition, whereas yellowness (b) significantly increased (p<0.05). In the texture analysis hardness, cohesiveness, springiness and gumminess were reduced by addition of broccoli powder. When we evaluated the sensory characteristics of five subareas (color, flavor, texture, taste, and overall acceptability), 7% broccoli sponge cake showed the highest sensory properties except for flavor (p<0.05). Therefore, the results suggested that 7% broccoli sponge cake could be helpful in improving physical quality and taste.

This study was conducted to investigate the effect of Hijikia fusiforme extracts on serum lipid and liver antioxidative enzyme activities in triton-induced hyperlipidemic rats. Sprague-Dawley male rats divided into 7 groups : We injected saline to a normal group (N), saline and tween 80 to control groups (CS, CT) and tot extracts to experimental groups (CSA, CTEtOH, CTE, CTH) for 7 days and then injected triton at the last day. Serum and liver free cholesterol contents were significantly lower in hexane-treated group (CTH) than control group (CT) whereas serum HDL-cholesterol content was higher in aqueous extract group (CSA) than control group (CS). Total cholesterol and phospholipid contents in serum and liver were lower in aqueous extract group (CSA) than control group (CS). Serum and liver triglyceride contents were significantly lower in ethanol (CTEtOH) and hexane treated group (CTH) than control group (CT). Thiobarbituric acid reactive substances of liver were lower in tot extract groups (CSA, CTEtOH, CTE, CTH) than control groups (CS, CT). Superoxide dismutase activities in liver were significantly lower in aqueous extracts group (CSA) and hexane treated group (CTH) than control groups (CS, CT). Liver catalase activity was the lowest in ethylacetate extract group. These results showed that some Hijikia fusiforme extracts have reduction effect of lipid and antioxidative effect in triton-induced hyperlipidemic rats.

This study was conducted to investigate the effect of 0.5% calcium lactate(CaL) on the fermentation of dough and quality and shelf-life of bread. Calcium lactates(CaL-A and CaL-P) were prepared from ash of black snail which contained shell and tissue together(ABS) and powder of the snail(PSB). pH of dough with the CaLs were higher than that of the control md, volume of the dough, loaf volume of bread were lower than those of the control products. But the volumes were almost the same when the pH of the dough were adjusted to pH 5.5. Mean calcium contents of treated bread (39.36~49.70 mg/100 g) were higher than that of control products(13.43 mg/100 g). There was no difference in Hunter $L^{*}$, $a^{*}$, $b^{*}$ values between the control and the treated group. Hardness and gumminess of CaL-A treated bread were the highest, but springiness and cohesiveness were the lowest. All the attributes showed no difference in case of pH adjustment(pH 5.5). The smaller pore and larger air cell with rough surface were observed in the CaL treated bread by SEM analysis. Sensory scores of CaL treated bread showed relatively lower values than those of the control products, but the scores increased by pH adjustment. The shelf-life of bread with CaL-P and CaL-A at 2$0^{\circ}C$ were 4 and 3 days, respectively, while that of the control group 1 day.day.y.

This study was performed to evaluate the quality characteristics and antioxidant activity of sikhe prepared using various concentrations of hot water extracts roasted coffee ground residue (CR-sikhe; 0.2, 0.4, 0.6, 0.8, and 1.0%). The pH increased with increasing CR concentration. The reducing sugar content after 5 h saccharification was the highest when 0.8% CR extract was used. Total polyphenol and flavonoid contents increased in a concentration-dependent manner reaching maximum levels when 1.0% CR-extract was used. The antioxidant activities of CR-extracts were higher than that of the control and increased dose-dependently. The CR-0.6 showed the best taste (4.28), color (4.56), flavor (4.08), and overall acceptability (4.28). After 10 day of storage at $4^{\circ}C$, the total cell count in CR-sikhe was approximately 1-2 log cycle, which was less than that in the control.

본 연구는 육성돈에 있어 인분해효소인 phytase의 첨가가 환경친화성사료개발을 위한 기초자료로 사용하기 위해 영양소 이용률을 측정하였다. 대조구는 옥수수-대두박의 육성돈 사료이고, 처리구는 대조구 사료에 Phytase의 첨가 수준을 500 unit 및 1,000 unit을 첨가한 구로 3×3 Latin Square 방법으로 실시하였다. 건물과 질소에 대한 소화율에서는 각 처리구간에 유의적인 차이가 없었다(P>0.05). 회분, 칼슘 및 인의 소화율의 경우 phytase 첨가구가 대조구에 비해 높은 수준을 보였다(P<0.05). 돼지가 섭취한 인의 양은 phytase 첨가구가 대조구에 비해 증가하였다. 또한 인의 흡수량에서 phytase 첨가구가 대조구에 비해 높았다(P<0.05) 분과 뇨의 총 인 배설량은 유의적인 차이를 나타내지 않았다. 칼슘의 섭취량은 처리구가 대조구에 비해 높았다. 칼슘의 분 배설량은 각 처리구간에 별 다른 차이를 보이지 않았으나(P>0.05), 뇨의 배설량은 처리구가 대조구보다 적은 양이 배설되었다. 소화된 아미노산 중 cystine, isoleucine, tyrosine, phenylalanine은 처리구가 대조구에 비해 소화율이 현저히 증가된 것을 알 수 있었다(P<0.05). Asparagine, threonine, serine, methionine, leucine의 경우 phytase를 500 unit 첨가한 구가 높은 소화율을 나타내었다(P<0.05). 한편 lysine, histidine, arginine 등의 다른 아미노산은 처리구가 대조구보다 약간의 소화율 증가를 보였으나 통계적 유의차는 나타나지 않았다(P>0.05). 결론적으로 인분해효소 phytase를 사료내 첨가하므로서 분중 영양소를 줄일 수 있는 환경친화성 사료를 개발 가능하다고 사료된다. 체결홈이 형성된 체결부를 갖는 안경집과 이것에 결합되는 체결구가 마련되어 개폐되는 커버가 형성된 케이스로 구성된다.로 금형설계 및 제작기간을 단축하고자 한다.ere demonstrated in rats after i.c.v., intraperitoneally and orally administration, respectively. The antiepileptical effects by the combination of compounds from ginseng; were compared with the iuluence of Rg1, Rb1, Rc and with the well known antiepileptical drugs such as carbamazepine, valproic acid. The base for the research is obtained by using the WAG/Rij strain (Luijtelaar, Coenen, Kuznetcova), an excellent genetic model for human generalized absence epilepsy. The improving action of gensinosides was effectively demonstrated on the model of electrical kindling of amygdala of WAG/Rij rats with genetically determined absences, and the influences of ginsenosides on the slow wave discharges have also been being investigated. The different characteristics of a kindling process exerted in the sex-dif

최근 노인인구의 증가와 함께 식생활의 변화에 의해 사망원인의 변화가 일어나고 있다 한국인의 주요 사망원인 중 뇌혈관 및 심장질환 등 순환기계 질환에 의한 사망이 증가하고 있는 추세이며, 심장순환계 질환의 위험요인인 고혈압의 이환률도 65세 이상 노인에게서 증가하고 있다. 고혈압은 만성질환으로 산화적 스트레스를 증가시키는 질환이므로 본 연구에서는 건강한 노인과 고혈압 노인의 체내 항산화 영양상태를 비교하기 위해 울산지역 50세 이상 노인을 대상으로 하였다. 대조군은 질환이 없거나 골다공증, 위장질환과 같은 기타 질환을 가진 사람 96명이었으며, 고혈압환자군은 고혈압을 가진 모든 질환자 118명이었고, 항산화 영양소 섭취나 혈장내 항산화 영양상태에 영향을 미치는 성별, 연령, 흡연 및 음주상태를 보정하여 비교하였다. 고혈압환자의 평균 유병기간은 6.1년이었으며, 항산화 비타민 섭취량은 비타민 A, retinol, $\beta$-carotene과 비타민 C 섭취량 모두 고혈압 유무에 따른 유의적인 차이가 나타나지 않았으나 고혈압환자의 섭취량이 높은 경향을 보였다. 한국인영양권장량과 비교한 결과 대조군의 비타민 A 섭취는 권장량의 86.2%, 고혈압환자군은 권장량의 103.0%를 섭취하여 고혈압군에서 유의적으로 높았고, 권장량의 75% 이하 섭취자의 비율은 대조군에서 46.9%, 고혈압군에서 41.5%로 조사되었다. 비타민 C 섭취는 대조군에서 권장량의 176.6%, 고혈압군에서는 189.0%로 나타나 질환의 유무에 관계없이 두 군 모두 권장량의 170%이상을 섭취하고 있었으나 권장량의 75% 이하를 섭취하는 사람의 비율이 대조군에서 13.5%, 고혈압군에서 17.0%로 고혈압군에서 높게 나타났다. 혈장 비타민 C의 농도는 대조군 15.3 mg/L, 고혈압환자 15.9mg/L, 혈장 $\beta$-carotene 농도는 대조군 0.21mg/L, 고혈압환자 0.22 mg/L로 나타나 고혈압 유무에 따른 차이가 없었고, 혈장 비타민 A,E 농도 및 총 항산화능력은 대조군에 비해 고혈압환자에게서 유의적으로 높게 나타났다. 또한 혈장 지질과산화물의 농도도 유의적이지는 않지만 고혈압환자에게서 높은 경향이 나타났다. 따라서 고혈압에 따른 항산화 영양상태를 비교한 결과 전반적인 항산화 비타민의 섭취량, 혈중 비타민 농도 및 총 항산화능력이 예상과 달리 대조군 보다 고혈압환자에게서 유의적으로 높게 나타났다. 이런 결과는 질환자들이 자신이 가진 질병의 진전을 막거나 치료의 목적으로 치료제를 복용하고, 식이요법을 실시하고 있기 때문으로 사료되며, 고혈압과 같이 산화적 스트레스가 증가하는 질환의 경우 체내 항산화 체계 반응이 이러한 변화에 효율적으로 대처하기 위한 방향으로 증가되었을 가능성이 있을 것으로 사료된다. 특히, 본 연구의 대상자들의 유병기간이 6.1년으로 비교적 길기 때문에 질환의 진행정도에 따른 항산화 상태를 측정하거나 비교적 질환으로 판정된 직후의 사람들의 대상으로 한 연구 등 더 많은 연구가 필요하다.

This study investigated the immunostimulatory effect of enzymatic porcine placental hydrolyzate (EPPH) in cyclophosphamide (Cy)-treated rats. This effect of EPPH prevented Cy-induced decreases in body, spleen, and thymus weights and natural killer (NK) cell activity. The numbers of immune cells, such as white blood cells, granulocytes, and lymphocytes, and mid-range absolute counts were significantly higher compared to the control group. The levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-2, IL-12, and immunoglobulin G (IgG) were notably reduced by Cy, while EPPH prevented these effects. Histopathological analysis of spleen samples revealed the protective effect of EPPH against Cy-induced immunosuppression. The findings demonstrate that EPPH can alleviate immunosuppression by cell viability, tissue damage, and regulation of the levels of cytokines. EPPH may have value as a component of immunostimulatory agents or an ingredient in functional foods.

This study aimed to replace the imported Chinese complete medium for Lentinula edodes with a newly-developed complete medium that is suitable for export as well. Three media compositions that supported fast mycelium growth and higher density, compared to that in the control, were chosen. Culture in the T13 medium reduced the incubation period for 'Nongjingo' by 12 days and for 'Cham-aram' by 10 days, compared to that required for the control; in addition, the number of days required for browning was greatly reduced for both varieties. The quantity of each mixed medium was increased according to the composition from the 1^st to the 5^th cycle by 5.9% for 'Nongjingo' and 12.6% for 'Cham-aram' in T13, compared to that in the control. A mixed medium comprising oak sawdust + Douglas fir sawdust + corn flour (40:40:20, v/v) was selected as the most suitable complete medium.

Purpose : Early surfactant therapy with either gentle ventilation, high-frequency ventilation or aggressive weaning of mechanical ventilation are principles for the treatment of respiratory distress syndrome(RDS). We studied to determine the accessibility of noninvasive nasal continuous positive airway pressure(CPAP) rather than mechanical ventilation by invasive intubation after early surfactant therapy. Methods : The study group consisted of 14 infants who were born and diagnosed with moderate respiratory distress syndrome and received early surfactant therapy with nasal CPAP of PEEP 5-6 cm $H_2O$ within two hours after birth in the Fatima neonatal intensive care unit for two years from January 1999 to August 2001. The control group consisted of 15 infants who were diagnosed with the disease and could be weaned from mechanical ventilator within five days after birth during the same period. Results : The characteristics, the severity of clinical symptoms and laboratory findings in the two groups at birth showed no significant difference. Neither did the interim analysis of laboratory data in two groups. Of 14 infants in the study group who received nasal CPAP after early surfactant therapy, only two infants showed weaning failure with this therapy. In the response cases, duration of CPAP was five days and mean airway pressure was $5.4{\pm}0.5cm$ $H_2O$. Two had the complication of CPAP with abdominal distension. Final complications and outcomes in the two groups showed no signifcant difference(P>0.05). Conclusion : The clinical courses in the two groups showed no significant difference. Therefore, we suggest that early surfactant therapy with noninvasive nasal CPAP is a simple and safe method rather than aggressive weaning after invasive mechanical ventilation in moderate respiratory distress syndrome.

$SO_2$ 폭로군의 기관 상피층의 섬모에서 DBA 및 SBA는 50ppm 이하 $SO_2$ 폭로군에서는 대조군에 비해 증가하였으며 sWGA 및 UEA-1은 대부분의 $SO_2$ 폭로군에서 대조군에 비해 증가하였다. 섬모세포에서 LCA 및 Con A는 100ppm 및 200ppm $SO_2$ 폭로군에서 대조군에 비해 약간 증가하였다. 배상세포에서는 대부분의 렉틴의 반응성이 50ppm 이하의 $SO_2$ 폭로군에서는 증가하였다가 100ppm 및 200 ppm $SO_2$ 폭로군에서는 현저히 감소하였다. 장액선포에서는 LCA 및 Con A는 모든 $SO_2$ 폭로군에서 대조군보다 증가하는 경향을 보였으며 점액선포에서는 대조군에서 관찰되지 않았던 RCA-1은 50ppm 및 100ppm $SO_2$ 폭로군의 일부 선포에서 증가하였다. 위의 결과로 보아 $SO_2$는 기관에 심대한 병리조직학적 변화뿐만 아니라 glycoconjugates대사에 심대한 영향을 미쳐 심한 병변을 야기시킴을 알 수 있었다. 전반적으로 $SO_2$의 호흡기 영향은 고농도로 갈수록 심한 영향을 나타내었다. 저농도에서도 폭로 시간이 길어짐에 따라 나타나는 $SO_2$의 영향이 고농도와 유사한 경향을 나타내며 또한 모든 $SO_2$의 농도를 비교해보면 폭로 시간이 길어질수록 그 영향이 더 심하게 나타났다.
