The purpose of this study was to compare the physicochemical properties of sausage manufactured with carp (Carassius carassius) muscle and pork. Sausages were prepared using either 100% pork sausage (P10), a mixture of 50% pork and 50% carp muscle (P5C5), or 100% carp muscle (C10). The quality of the sausage emulsion was determined by analyzing approximate composition, pH, instrumental color, cooking yield, water holding capacity (WHC), viscosity, and texture profile analysis (TPA). Moisture content of cooked C10 was significantly higher than that of P10 or P5C5 (p < 0.05); however, protein content of cooked P10 was significantly higher than that of C10 (p < 0.05). The pH of uncooked and cooked C10 was significantly higher than that of P10 and P5C5 (p < 0.05). The cooking yield, WHC, and texture profile analysis of C10 were higher than those of P10 and P5C5 (p < 0.05). In addition, the viscosity of uncooked C10 was higher than that of P10 and P5C5. These results suggest that carp muscle can enhance sausage quality with respect to pH, WHC, cooking yield, viscosity, and TPA.

To develope the novel baculovirus transfer vector, the p10 gene was cloned from the Bombyx mori nuclear polygedrosis virus (BmNPV) vB2 strain isolated from the B. mori larvae of sericultural farms. The novel transfer vector was constructed by using the p10 gene of BmNPV vB2 strain was 210 bp. The TAAG sequence at the -71 bp of upstream from translation initiator ATG and two polyadenylation signal site at the downstream from terminator TAA were also detected in the p10 gene. The 5' and 3' flanking region of the p10 gene amplified by PCR was cloned into pBluescriptII SK(+) and then transfer vector pBm10 was construceted. The 7.9 kb pBm10 was analysed by restriction enzymes and the map was confirmed. In order to determine the expression of foreign gene of pBm10, $\beta$-galactosidase gene was inserted in the SmaI site of foreign gene cloning site of pBm10. The pBm10 containing $\beta$-galactosidase gene was cotranfected wth genomic DNA of BmNPV vB2 into BmN-4 cells. The recombinant baculovirus expressing $\beta$-galactosidase was also produced polygedra in the infected cells. The results indicated that pBm10 is functional, suggesting that in the baculovirus expression vector system, the recombinant virus produced by pBm10 was effective by oral infection for the producing recombinant proteins in in vivo expression.

증폭된 재조합 trp operon의 발현을 위한 숙주박테리아 개발의 일환으로 숙수 E. coli에 $aroP^{-}$ 변이를 도입하였다. $aroP^{-}$ 변이의 유도에는 trans po son Tn10을 사용하였으며 P1Kc파아지를 이용하여 숙주박테리아에 형질도입하였다. General aromatic amino acid transport system이 결여된 $aroP^{-}$ 변이주는 $\beta$-thienylalanine ($(2{\times}10^{-4}M)$). p-fluor-phenylalanine ($(2{\times}10^{-4}M)$) 그리고 5-methyltryptophan에 저항성을 가졌다. $aroP^{-}$ 변이주는 $aroP^{-}$ 야생주에 비해서 〔$[^3H]$-tryptophan uptake가 상당히 감소하였다. 또한 NaN, ($(2{\times}10^{-4}M)$)를 처리하였을 때의 ($[^3H]$)-tryptophan uptake 비율은 aroP 변이주가 $aroP^{-}$야생주보다 덜 감소하였다. E. coli $trpR^{-ts}/ColE_1 -trp^+$ 균주에 aroP 형질을 도입하였을 때 트립토판 방출이 $aroP^{-}$ 야생주에 비해서 4 배나 증가하였다.

Pseudomonas putida KU816에서 분리한 플라스미드 pKU10의 여러가지 특성을 조사하고 그 제한 효소 지도를 작성하였다. pKU 10은 암펴설런, 테트라사이클린, 클로람페니콜에 대한 내성 유전자를 갖는 작은 R factor로서 마이토마이신 C에 의하여 큐어링 된다. 플라스미드의 크기는 9.4Kb로 측정되었다. pKU 10은 Pseudomonas와 E.coli블 숙주로 하였을 때 안정하게 형질 발현이 되다. 또한 pKU 10의 불화합성균은 IncP-I으로 조사되었다. Eco RI, Xho I. SaiI, BglII, SmaI은 pKU 10 DNA를 한 부위에서 자르고, Pst I은 두 부위, Hind Ill는 여섯 부위에서 자른다. 제한 효소 지도는 제한 효소를 이중, 삼중으로 완전 소화시키거나, 부분 소화시켜서 얻었다. pKU 10은 Pseudomonas속에서 유용한 클로닝 벡터호 이용된 것으로 기대된다.

새로운 미세공구조를 갖는 제올라이트성 물질인 ETS-4와 ETS-10의 합성에 pH가 미치는 영향을 조사한 결과, pH가 10.4인 경우 세공의 크기가 약 $8{\AA}$인 ETS-10가 합성되는 반면 pH가 증가하면서 두 종류가 동시에 합성되는 것을 알 수 있었다. 그러나 pH가 11.5인 경우에는 순수한 ETS-4만이 합성되는 것을 알 수 있었다. Morphology를 보면 ETS-10의 경우 정점이 잘린 두 개의 피라미드를 겹쳐놓은 형상에서 pH가 증가함에 따라 순수한 ETS-4의 경우 판상형의 결정체들이 형성되는 것을 알 수 있었다.

야생주 핵다각체병 바이러스의 낮은 병원성에 대해 살충제로서의 파밤나방 핵다각체병 바이러스(Spodoptera exigua nucleopolyhedrovirus: SeNPV)의 병원성 향상을 꾀함과 동시에 재조합 바이러스가 다각체 내에 매립됨으로써 살충제로의 적용시 야외에서의 안정성을 확보할 수 있는 p10 유전자의 프로모터를 이용한 새로운 발현벡터를 개발하기 위하여 국내분리주 SeNPV의 p10 유전자 구조를 분석하였다. 그 결과, SeNPV p10 유전자의 프로모터와 구조유전자 부위를 포함한 545염기서열을 결정하여 기존에 보고된 SeNPV p10 유전자(Zuidema et al., 1993)와 비교한 결과 구조유전자 부위에서는 100%의 상동성을 보였으나 5` 및 3` flanking region의 4개의 염기서열에서 차이를 보였다. Southern hybridization에 의하여 SeNPV전체 genomic DNA상에서 p10 유전자는 Sph I 2.4Kb와 Cla I 4.0Kb 단편내에 각각 존재함을 확인하였으며, p10 유전자를 포함하는 이들 단편을 각각 클로닝하여 제한효소 지도를 작성한다.

The intake of fatty acids, and the effects of fatty acid intake patterns on serum lipid concentrations was investigated in 112 postmenopausal women. Dietary intakes of fatty acids were assessed by means of a semi-quantitative food questionnaire with food models and other measuring tools. The intakes of saturated fatty acid(SFA), monounsaturated fatty acid(MFA) and polyunsaturated fatty acid(PUFA) were 10.85g, 11.89g and 12.09g, respectively. The ratios of P/M/S and $\omega$6/$\omega$3 fatty acid were 1.19 : 1.10 : 1 and 6.65 ; 1, respectively. Serum lipid concentrations were adjusted for age, menopausal period, BMI, stress scores, exercise habit and energy intake and the relationship between fatty acid intake and serum lipids was measured using Pearson's correlation coefficient. Serum cholesterol concentration was positively correlated with dietary intake of SFA (p<0.10), MUFA(p<0.05), palmitic acid(p<0.10), stearic acid(p<0.05), oleic aicd(p<0.05), and arachidonic acid(p<0.10). Serumk LDL-cholesterol concentration was positively correlated with MUFA(p<0.10), oleic acid(p<0.10), oleic acid(p<0.10), and arachidonic acid (p<0.10). Serum triglyceride concentration was positively correlated with arachidonic acid(p<0.10). However, serum HDL-cholesterol concentration was not found to be significantly correlated with any fatty acids.

The porphyrin-incorporated arylether dendrimers ZnP-D1 and ZnP-D4 were investigated to discover the influence of dendritic environments for the axial ligation of pyridine and photoinduced electron transfer by methyl viologen. Absorption and fluorescence spectra of ZnP, ZnP-D1, and ZnP-D4 were measured in dichloromethane with the addition of pyridine or methyl viologen dichloride. Axial ligation of pyridine was confirmed by red-shifted absorption spectrum. The complex formation constants $K_f$ (Table 1) for axial coordination of pyridine on ZnP, ZnP-D1, and ZnP-D4 were estimated to be $4.4{\times}10^3\;M^{-1}$, $3.3{\times}10^3\;M^{-1}$, and $1.7{\times}10^3\;M^{-1}$, respectively. The photoinduced electron transfer to methyl viologen dichloride was confirmed by fluorescence quenching. Stern-Volmer constants Ksv for ZnP, ZnP-D1, and ZnP-D4 were calculated to be $2.6{\times}10^3$, $2.5{\times}10^3$, and $2.1{\times}10^3$, respectively. ZnP-D4 surrounded by 4 aryl ether dendrons shows the smallest $K_f$ and Ksv values, with comparison to ZnP and ZnP-D1.
