Objectives In this study, the effects of Ja-eum-gang-hwa-tang (JGT) on the increase in airway epithelial mucosubstances of rats and ATP- or PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production and gene expression from human airway epithelial cells were investigated. Materials and Methods Hypersecretion of airway mucus was produced by exposure of $SO_2$ to rats for 3 weeks. The effect of orally-administered JGT for 2 weeks on increased epithelial mucosubstances from tracheal goblet cells of rats was assessed by using histopathological analysis after staining the epithelial tissue with Hematoxylin-eosin and PAS-alcian blue. Possible cytotoxicity of JGT was assessed by investigating the potential damage on kidneys and liver functions by measuring serum GOT/GPT activities and serum BUN concentration of rats and the body weight gain during experiment. Also, the effect of JGT on ATP- or PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production and gene expression from human airway epithelial cells (NCI-H292) were investigated. Confluent NCI-H292 cells were pretreated for 30 min in the presence of JGT and treated with ATP ($200{\mu}M$) or PMA ($10ng/ml$) or EGF ($25ng/ml$) or TNF-${\alpha}$ (0.2 nM) for 24 hrs to assess the effect of JGT both on ATP- or PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production by using enzyme-linked immunosorbent assay (ELISA) and on gene expression by the same inducers using reverse transcription-polymerase chain reaction (RT-PCR). Results (1) JGT decreased the amount of intraepithelial mucosubstances of trachea of rats. (2) JGT did not show any renal and hepatic toxicities, and did not affect body weights either. (3) JGT significantly inhibited ATP-, PMA-, EGF-, and TNF-${\alpha}$-induced MUC5AC mucin productions from NCI-H292 cells. (4) JGT inhibited EGF-, and PMA-induced expression levels of MUC5AC gene in NCI-H292 cells. However, ATP- and TNF-${\alpha}$-induced MUC5AC gene expression levels were not affected in NCI-H292 cells. Conclusions The result from the present study suggests that JGT might control the production and gene expression of airway mucin observed in various respiratory diseases which accompanied by mucus hypersecretion. Also, JGT did not show liver toxicity or impact on kidney functions. The effect of JGT should be further studied by using animal experimental models which can show proper pathophysiology of airway diseases.

Objectives In this study, the author tried to investigate whether piryongbang-gamgil-tang (PGGT) significantly affect in vitro airway mucin secretion, PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production / gene expression from human airway epithelial cells and increase in airway epithelial mucosubstances and hyperplasia of tracheal goblet cells of rats. Materials and Methods For in vitro experiment, confluent RTSE cells were chased for 30 min in the presence of PGGT to assess the effect of PGGT on mucin secretion by enzyme-linked immunosorbent assay (ELISA). Also, effect of PGGT on PMA- or EGFor TNF-${\alpha}$-induced MUC5AC mucin production and gene expression from human airway epithelial cells (NCI-H292) were investigated. Confluent NCI-H292 cells were pretreated for 30 min in the presence of PGGT and treated with PMA (10 ng/ml) or EGF (25 ng/ml) or TNF-${\alpha}$ (0.2 nM) for 24 hrs, to assess both effect of PGGT on PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production by ELISA and gene expression by reverse transcription-polymerase chain reaction (RT-PCR). For in vivo experiment, the author induced hypersecretion of airway mucus and goblet cell hyperplasia by exposure of rats to $SO_2$ during 3 weeks. Effect of orally-administered PGGT during 2 weeks on increase in airway epithelial mucosubstances from tracheal goblet cells of rats and hyperplasia of goblet cells were assesed by using histopathological analysis after staining the epithelial tissue with alcian blue. Possible cytotoxicities of PGGT in vitro were assessed by examining LDH release from RTSE cells and the rate of survival and proliferation of NCI-H292 cells. In vivo liver and kidney toxicities of PGGT were evaluated by measuring serum GOT/GPT activities and serum BUN/creatinine concentrations of rats after administering PGGT orally. Results (1) PGGT did not affect in vitro mucin secretion from cultured RTSE cells. (2) PGGT significantly inhibited PMA-, EGF-, and TNF-${\alpha}$-induced MUC5AC mucin productions and the expression levels of MUC5AC mRNA from NCI-H292 cells. (3) PGGT decreased the amount of intraepithelial mucosubstances and showed the tendency of expectorating airway mucus already produced. (4) PGGT increased LDH release from RTSE cells. However, PGGT did not show in vivo liver and kidney toxicities and cytotoxicity to NCI-H292 cells. Conclusion The result from this study suggests that PGGT can regulate the production and gene expression of airway mucin observed in diverse respiratory diseases accompanied by mucus hypersecretion and do not show in vivo toxicity to liver and kidney functions after oral administration. Effect of PGGT with their components should be further studied using animal experimental models that reflect the diverse pathophysiology of respiratory diseases through future investigations.

체외에서 한우 난포란의 감수분열과 배발달 능력의 획득에는 단백질 합성이 수반되어야 한다. 그러나 이러한 변화와 관련된 연구 보고는 거의 전무한 실정이다. 본 실험은 난자의 핵성숙과 관련된 세포질내 단백질 변화를 파악하기 위하여, 체외성숙 시간에 다른 배발달율과 세포질내 단백질을 비교하여 배발달능력 획득과 관련 있는 단백질을 규명하고자 실시하였다. 한우 난소에서 2-8mm의 가시난포로부터 난포란을 회수하였다. 회수된 난포란은 10% FBS와 호르몬이 첨가된 TCM199 용액에서 18시간 또는 24시간 체외성숙을 실시하였다. 난자 세포질내 단백질 변화는 2D gel electrophoresis를 이용하였고, 유의적인 변화를 나타낸 spot은 peptide mass fingerprinting을 통하여 단백질 동정을 실시하였다. 체외수정은 fer-TALP 용액을, 체외배양은 CR1aa 용액을 배양 3일째까지는 0.3% BSA, 그 이후에는 10% FBS와 난관상피세포를 첨가하여 사용하였다. 통계분석은 t-test를 이용하였다. 난자의 세포질에 대한 이차원전기영동 결과 29개의 단백질 spot들을 확인하였다. 한편 체외성숙 18시간째에 PB가 출현된 난자는 PB가 출현되지 않은 난자에 비하여 15개의 spot에서 유의적인 변화를 나타냈다. 이들 중 4개의 단백질 spot은 낮았고, 11개 spot의 수준은 높은 경향이었다. 체외성숙 18시간째와 24시간째의 배발달율을 조사한 결과 18시간째에서 유의적으로 높은 배반포 발달율을 나타냈다. 그리고 체외성숙 18시간과 24시간째 난자의 세포질내 단백질 spot들의 변화를 비교한 결과 PB가 출현된 난자 세포질에서 단백질의 변화와 유사한 경향이었다. 그러나 2개의 단백질 spot은 상반된 경향을 나타냈다. 따라서 본 실험에서 난자의 핵성숙과 관련 있는 15개의 spot을 확인하였고, 이들 단백질 spot중에서 2개가 배발달 능력과 관련이 있을 것으로 사료된다.보다는 육질등급에 많은 영향을 받는 것으로 판단된다. 한편 육질 1등급에서 배발달율이 낮은 이유는 육질 향상을 목적으로 암소를 비육 하는 경우 발생하는 번식장애와 밀접한 관계가 있는 것으로 사료된다.각각 가장 높았다. 배양 8일째 배반포의 세포수에 있어서 총세포수와 TE 세포수는 차이가 없었으나, ICM 세포수가 l0mg 첨가군에서 가장 높았다. 본 실험 결과에서 체외성숙 배지에 NEAA와 EAA 첨가가 배발달율에는 효과가 없었지만, 첨가농도의 증가에 따라 ICM 세포수가 증가하였다. 한편 체외성숙 배지에 LAH 첨가는 첨가 농도가 높을수록 배발달율은 낮았지만 ICM 세포수는 증가하였다.에 Csk가 관여하고 있음을 알 수 있다. 결론적으로 성적 성숙에 따른 생쥐 정소 내 Src-Csk loop의 발현과 Src kinase 활성의 변동은 정소 내 간충조직, 세정관 상피의 증식 및 기능적 분화 과정을 매개하는 생리적 활성분자 수용체 하위의 신호전달 과정에 Src-Csk loop에 의한 조절가능성을 확인할 수 있었다.rugrene의 향기성분이 주요 성분군으로 확인되었다. 2. 생강나무에서 생강의 향기를 발산하는 성분으로는 $\beta$-myrcene, o-terpinolene, phellandrone, ι-limonene, $\beta$-eudesmol, $\delta$-cadinone, elemol, trans-caryophyllene으로 동정되었으며 그 중에서도 phellandrene, $\beta$-eudesmol이 주된 역할을 하는 성분으로 확인하였다. 유의적인 관련성이 나타났고, 복부 비만의 지표인 허리엉덩이둘레비는 GPT, alkaline phosphatase, 공복시 혈당 및 MCV 등 다양한 건강지표와 관련성을 나타내어 향후 비만에 있어 다양한 혈액 성상의 변화 및 역할규명에 대한 연구가 이루어져야 할 것으로 본다.hat

Two experiments were conducted to investigate the effect of feeding cyanidin 3-glucoside (C3G) high black rice bran on nutrient digestibility, blood measurements, growth performance and pork quality of pigs. In Exp. I, a total of fifteen pigs (19.91${\pm}$1.80 kg, average initial body weight) were used in assay of nutrient digestibility and blood measurements. All pigs were allotted to 5 treatments with 3 replicates according to a completely randomized design (CRD) in an individual metabolic crate. Treatments included 1) CON: basal diet, 2) BRB-2: basal+brown rice bran 2%, 3) BRB-4: basal+brown rice bran 4%, 4) CRB-2: basal+C3G high black rice bran 2% and 5) CRB-4: basal+C3G high black rice bran 4%. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA) and crude fiber (CF) was not affected by dietary treatments. Serum triglyceride (TG) and high density lipoprotein (HDL) cholesterol concentrations were not affected by addition of C3G high black rice bran. However, at the end of experiment, pigs fed rice bran showed decreased tendency in total cholesterol concentration. Especially pigs fed C3G high black rice bran showed significantly lower total cholesterol concentration compared to pigs fed brown rice bran (p<0.03). There was numerically lower total cholesterol concentration with increasing levels of black rice bran in the diet. In terms of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT), there were no significant differences among treatments, even though pigs fed CRB-4 showed the lowest GOT concentration compared to other pigs. In Exp. II, sixteen finishing pigs (average initial body weight 89.96${\pm}$0.35 kg) were divided into 4 treatments to investigate the effect of feeding C3G high black rice bran on growth performance and pork quality. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among the treatments. Pigs fed C3G high black rice bran showed numerical decrease in ADG and increase in FCR while not effecting feed intake. There was no significant difference in live weight, carcass weight, carcass rate, backfat thickness and carcass grade. However, pigs fed C3G high black rice bran tended to show lower backfat thickness than pigs fed basal diet. Pigs fed C3G high black rice bran showed a tendency of decreased TBA value than pigs fed basal diet, although there was no overall significant difference among treatments. In conclusion, nutrient digestibility, blood measurements, growth performance and pork quality were not significantly affected by feeding C3G high black rice bran to pigs. However, C3G high black rice bran might have an effect on lowering serum total cholesterol and decrease the TBA value in pork compared to control group and these effects might be due to high concentration of antioxidative compounds in C3G high black rice bran.

개불 당단백질의 sarcom 180 cell 고형암 성장 저지능은 4mg/kg에서 43.63%로 나타났으나, 20mg/kg이상의 농도에서는 고형암 성장 저지능을 보이지 않았다. Sarcom 180 cell에 대한 수명 연장 실험에서도 2mg/kg와 4mg/kg의 저농도에서는 상당한 수명연장 효과를 보였으나, 2Omg/kg 이상의 고농도 투여군에서는 수명연장 효과를 나타내지 않았다. 개불 당단백질의 sarcoma 180 cell에 대한 직접적인 세포 독성 효과는 농도의 증가에 따라 약간의 종양세포 살해효과를 보였으나, 그 효과는 미약하였다. 개불 당단백질의 면역능 증진효과는 체중에 대한 간과 비장의 중량비 증가, 총 복강세포수의 증가 그리고, 당단백질을 고농도 투여시 30.78%~46.30%정도의 백혈구 수 증가 등으로 확인되었다. 이러한 결과로서 개불에서 추출한 당단백질의 항암효과는 면역활성의 증진과 면역자극의 효과라고 볼 수 있었으나, 전반적인 면역활성의 증가에도 불구하고, sarcoma 180 cell에 대한 고형암 성장 저지실험과 수명연장실험에서 고농도로 투여시에는 오히려 활성이 나타나지 않았다. 따라서 개불 당단백질의 최적투여 농도와 고농도 투여시의 부작용에 관한 더 많은 연구가 필요하였다. 이상의 결과에서 개불에서 추출한 당단백질의 면역자극에 의한 항종양 활성을 확인 되므로, 일반적으로 사용되어지는 항암 화학요법제와 더 불어 병행될 수 있는 면역증진제로서의 개발 가능성이 있다고 보여진다.

본 연구에서는 참나무(oak wood)류중 신갈나무(Querrus mongolica)로부터 수용성 식이섬유소의 제조와 제조된 수용성 식이섬유소의 생리적 기능성을 검정하고자 하였다. 신갈나무로부터 수용성 식이섬유소의 분리는 전처리 기술로써 폭쇄처리를 하였으며 최적 폭쇄전처리 조건은 25kgf/$\textrm{cm}^2$의 압력으로 6분간 처리하였다. 폭쇄시료를 탈리그닌 처리하기 위해 가장 효과적인 방법중 1% NaOH 용액으로 수회여과 처리 하였다. 앞에서 탈리그닌된 시료를 효소가수분해 처리하기 위 해 사용된 효소로는 Onnozok R-10보다 Cellusoft 효소의 가수분해율이 효과적이었다. 제조된 수용성 식이섬유소의 분자량 분포는 약 1,200-348 사이에 존재하는 oligomer 형태의 소당류로 분포되어 있었다. 제조된 수용성 식이섬유소의 생리적 기능성을 검정하기 위해 실험동물은 Sprague-Dawley종 수컷을 이용하여 정상군과 고콜레스테롤식이 실험군으로 나눈 후 고콜레스테롤 실험군을 다시 섬유소 종류와 공급수준에 따라 섬유소를 공급하지 않은 무섬유식이군 (FF군), 시판 식이섬유소를 5%공급한군 (5P군) 10%공급한군 (l0P군) 제조 식이섬유소를 5% 공급한 군 (5M군) 10% 공급한 군(10M군) 등 각 10마리씩 6군으로 나누어 4주간 사육하였다. 식이섭취량은 섬유소공급군이 FF군에 비해 증가되었으며 체중증가량은 섬유소공급군에서 FF군에 비해 유의적 (p<0.05)으로 낮았다. 식이효율은 FF군에 비해 모든 식이섬유소군에서 유의적 (p<0.05)으로 낮았으며 특히 10% 공급군에서 가장 낮았다. 간 무게근 FF군에 비하여 식이섬유소 공급군에서 유의적 (p<0.05)으로 감소되었으며 소장 및 맹장무게는 정상군과 무섬유식이군에 비하여 식이섬유소 공급군에서 증가되었다. 혁청 GOT 활성은 식이섬유소 공급군이 FF군에 비해 유의적 (p<0.05)으로 저하되었다. GPT 활성은 정상군에 비해 무섬유식이군인 FF군에서 증가되었으며 섬유소 공급관들은 다소 감소되는 경향이었다. 간조직 중 GST 활성은 FF군에 비해 식이섬 유소 공급군 모두 활성이 증가되었다. 그리고 이러한 생리적 기능은 제조된 수용성 섬유소군이 시판 수용성 섬유소와 차이가 없었다. 결론적으로 제조된 수용성 식이섬유소와 시판되는 수용성 식이섬유소가 생리져 기능이 거의 비슷하고 무독성이 관찰됨으로써 신갈나무로부터 제조된 수용성 식이섬유소의 제조 방법이 우수하다고 볼 수 있다.
