This study was to demonstrate a rapid novel method for detection of adulterated cow milk in goat milk using modified staining protocol after native polyacrylamide gel electrophoresis (PAGE). Samples of cow milk and goat milk containing 0, 0.5, 1.0 and 2.0% (v/v) of cow milk were analyzed. Low levels of cow milk mixed in goat milk were identified by the presence of higher mobility of $\beta$-lactoglobulin A ($\beta$-Lg A) in cow milk. By mini-gel electrophoresis, a distinguishable protein profile was visualized in 25 min using the modified Coomassie blue staining solution, in which methanol (50%) was replaced with ethanol (20%) and the concentrations of Coomassie blue and acetic acid were reduced from 2 to 0.13% and 10 to 5%, respectively. To visualize the milk proteins, gels in the staining solution were water-bathed in boiling water for 5 min and then cooled down immediately for 3-5 min. The sensitivity of this method is relatively high, allowing examination of 1% cow milk in goat milk. The procedure presented here is also very cost-effective due to less reagents needed. This simplified method would be useful and applicable to dairy industry for routine examination of goat milk.

부산(傅山, 1607~1684)은 명말청초에 매우 현실참여적 삶을 살았던 인물이다. 부산이 바라보는 당대의 지식인들은 정주(程朱)의 빈껍데기에 의지하여 도학선생이라고 허풍을 떨면서 자리만 지키고 있는 허수아비들이었다. 그는 리(理)와 기(氣), 성(性)과 정(情) 등만을 논의하는 것은 현실세계의 활발한 실용적 측면을 도외시한 채 추상적 사유에만 머물게 하여 현실 세계의 다양성을 무시하는 부작용을 낳는다고 보았다. 부산의 이러한 사유는 정치사상이나 문학론에 고스란히 드러난다. 그는 기적 세계보다 먼저 그것을 규제하고 통제하는 리가 존재한다는 송명 리학(理學)의 주장은 일종의 도덕적 이데올로기를 창출하여 봉건적 전제주의를 이론적으로 합리화하는 논리 틀을 제공한다고 보았다. 따라서 부산에게 있어 성인은 이러한 사회의 불합리한 요소를 척결하는 사회 개변가이며 혁명가였다. 부산은 문학도 활발발한 기의 세계를 표현할 수 있어야 한다고 보았다. 자유분방한 광(狂)의 경지, 창조적인 경지가 진정한 문학이라고 보았다. 옛 문체나 흉내내면서 고답적인 작문을 하는 것은 천기(天機)의 자연스러움을 거스르는 행위였다. 글은 변화무상한 활발발한 세계를 표현할 수 있어야 하는 것이었다.

Following is the result through translating. studying, and analyzing San Zhi Shan(三指禪), the book worked by Zhou Xue Ting(周學霆). 1. The chapter of Mai Xue Yuan Liu(脈學源流) explains the Xiang Shu Xue(象數學) viewpoint, the part that pulse is based on Lu guan(律管). 2. The chapter of Liu Bu Mai Jie(六部脈解) explains that emphasizing Shen(神) through understanding the shape of pulse(脈象) is more important than the locating the area of the shape of pulse(脈象). 3. The chapter of Zuo Xin Tan Zhong Can Dan Shen Xiao Chang You Fei Xiang Zhong Pi Wei Ming Da Chang Bian(左心膽中肝膽腎小腸 右肺胸中脾胃命大腸辨) exhibits the different view about the position of pulse from Li Shi Zhen(李時珍)'s. the chapter in which Zhou(周) arranges Heart{\cdot}Small\;Intestine{\cdot}Liver{\cdot}Gall\;Bladder{\cdot}Kidneys{\cdot}and$ Bladcler(心 小腸 肝 膽 腎 膀胱) in left hand and $Lungs{\cdot}Large{\cdot}Intestine{\cdot}Spleen{\cdot}Stomach{\cdot}Kidney{\cdot}and$ The gate of Vitality(肺 大腸 脾 胃 腎 命門) in right hand. From the above results, I'm sure that San Zhi Shan(三指禪)which has headed down to descendants as the special book about the study of pulse has developed the theory of pulse. Therefore I expect that the more profound study about this will be going on.

Gardeniae Fructus (Gardenia jasmmoides Ellis) is widely used as a natural food colorant and as a traditional medicine for the treatment of hepatic and inflammatory diseases. The quality evaluation of Gardeniae Fructus was carried out by HPLC using geniposide as a marker. The geniposide was isolated from commercial Gardeniae Fructus on ODS column using a mixed solvent of acetonitrile-water (v/v 9:91) as mobile phase and a detection wavelength 240 mm. The content of geniposides in twenty different samples was in a range of 1.20% to 7.17% of total tissues and the average was 4.97%.

Accompanied by the demand of thin type TV, the application of the TFT LCD display device is more and more extensive. The key material which influences the optical performance of the TFT LCD is optical film. Due to the rapid development of the big size TFT LCD for the recent years, the supply has been unable to meet the demand for its relative material. Therefore, we bring up a alternate choice-the hybrid compensation film which could not only show well optical performance, but also lessen the quantity of usage in TAC in order to make the optical film free of shortage.

Breast cancer metastasis is the most common cause of cancer-related death in women. Thus, seeking targets of breast tumor cells is an attractive goal towards improving clinical treatment. The present study showed that CCL18 from tumor-associated macrophages could promote breast cancer metastasis via PITPNM3. In addition, we found that pachymic acid (PA) could dose-dependently inhibit migration and invasion of MDA-MB-231cells, with or without rCCL18 stimulation. Furthermore, evidence was obtained that PA could suppress the phosphorylation of PITPNM3 and the combination of CCL18 and PITPNM3. Therefore, we speculate that PA could inhibit breast cancer metastasis via PITPNM3.

Two types of immunoloigcal probes, anti-ABBP Abs, have been developed. The purified ABBP from ABA-C1-BSA-sepharose 4B column was identified by PAGE and appeared in one band of about 56KD, as well as showed a specific binding ability and a high affinity for ABA (Kd2.0$\times$10-9 mol/L). Unexpectedly, the existence of rRNA with a length of around 300 nucleotides could be found, when the ABBP was digested with proteinase K and identified by eletrophorsis on an agarose gel (1%). As a result, about 120 cDNA clones coding maize 17s RNA and only one cDNA clone coding ABBP (24cDNA) were obtained from 200,000 seperated phage plaques by the anti-ABBP pAbs. 24cDNA had 1075bp and contained an open reading frame coding 254 amino acids. The anti-idiotypic Ab raised against an ABA MAb showed the ability of either mimicking ABA or competing with ABA. The localization of ABBPs in plant cell was investigated.

This study developed a natural ingredient as a functional food possessing properties of attenuation of hypertension and cardiovascular hypertrophy. In a previous study hydrolysates obtained from chicken leg bone protein using Alcalase strongly inhibited angiotensin I converting enzyme (ACE) in vitro. In particular, hydrolysate (A4H) from four hours of incubation exhibited the highest ACE inhibitory activity (IC50 = 0.545 mg/ml). A4H was selected as a potent ACE inhibitor and orally administrated to spontaneously hypertensive rats (SHR) for eight weeks to investigate attenuating effects on age-related development of hypertension and cardiovascular hypertrophy. Results showed that treatment with A4H of SHRs attenuated the development of hypertension as effectively as the clinical antihypertensive drug captopril. Moreover, a significantly lower heart to body weight ratio and thinness of coronary arterial wall was observed in SHRs that had been treated with A4H or captopril. The results suggest that A4H can be utilized in developing an ACE inhibitor as a potential ingredient of functional foods to alleviate hypertension and cardiovascular hypertrophy.

A series of 5-alkoxy-tetrazolo[1,5-a]quinolines were synthesized to evaluate their anticonvulsant and antidepressant effects. Anticonvulsant effects and neurotoxicity of the compounds when injected intraperitoneally to mice were determined by a maximal electroshock (MES) test and a rotarod test, respectively. Only three of the synthesized compounds (4a, 4b, 4c) displayed anticonvulsant activity at a dose of 300 mg/kg. Most of the compounds significantly reduced immobility times during the forced swimming test (FST) at a dose of 100 mg/kg, indicative of antidepressant activity. Among the compounds, 5-(2-fluorobenzyloxy)tetrazolo[1,5-a]quinoline (4k) reduced immobility time by 66.85% at 30 mg/kg compared with the same dose of Fluoxetine, which reduced immobility time by 52.30%. According to the results of the 5-Hydroxytryptophan induced head-twitch test and yohimbine toxicity potentiation test, the noradrenergic system seems not to be involved in the antidepressant-like effect of compound 4k while the serotonergic system seems a little to be involved.

Twenty six compounds (1-26) were isolated from the root barks of Ulmus davidiana var. japonica. The anti-inflammatory activity of the isolated compounds were evaluated agai nst the generation of inflammatory chemical mediators in bone marrow-derived mast cells. Among them, compounds 10, 11, 13, 15 and 19 inhibited not only cyclooxygenase-2 dependent prostaglandin $D_2$ generation but also 5-lipoxygenase dependent leukotrien $C_4$ generation in a concentration-dependent manner. In addition, compounds 11, 12, 13, 15 and 19 also inhibited $\beta$-hexosaminidase release, a marker of mast cell degranulation reaction, from bone marrow-derived mast cell. These results suggest that the anti-inflammatory activity of U. davidiana might in part occur by both the inhibition of eicosanoid generations and the degranulation reaction of mast cells.
