본 연구는 위장 단계의 소화과정에 관여하는 Gastric lipase (GL)를 반려견을 위한 정적 체외 소화모델(Static in vitro digestion model)에 적용을 검토하기 위하여 실시되었다. GL의 첨가가 체외 소화과정 동안 건물(Dry matter; DM), 조단백질(Crude protein; CP) 그리고 조지방(Ether extracts; EE) 소화율에 미치는 영향을 평가하였다. GL은 위장 소화단계에서 첨가되었다. 위장(39℃, 2 hr.)과 소장(39℃, 4 hr.) 소화 후에 비소화 분획을 분리하였다. 그리고 실험사료와 분리된 비소화 분획에서 DM, CP 그리고 EE 수준을 측정하고 각각의 소화율을 계산하였다. 위장과 소장 소화단계에서 측정된 DM, CP 그리고 EE 소화율은 Control과 GL 그룹 사이에서 통계적으로 유의한 차이는 관찰되지 않았다(p>0.05). 결과적으로 우리의 체외 소화모델에서 GL의 첨가는 DM, CP 그리고 EE의 소화율에는 영향을 미치지 않는 것으로 나타났다. 따라서 이와 같은 결과는 정적 체외 소화모델을 이용한 소화율의 평가에 있어서 GL의 역할은 다소 제한적일 수 있다는 것을 시사한다.

  Recently, the increasing trend for the transshipment traffic of Busan port in Korea is slowing down because of the extensive development plan of domestic ports in china. For solving this problem, Korea is going on the project for preoccupying the transs

Legume seed isoflavones may have a variety of desirable physiological effect on the human health including both the circulatory and skeletal systems. The present study was performed to determine the isoflavone content of leaf and seed as well as to purify and identify the types of isoflavone from leaf extract of hyacinth bean (Lablab purpureus (L.) Sweet). Reverse phase HPLC revealed six different types of isoflavone such as daidzin, genistin, daidzein, genistein, 6"-o-acetyl genistin and 6"-o-acetyl daidzin in aqueous methanol extract from seeds and leaves of the hyacinth bean. Relatively, leaf isoflavone content of hyacinth bean was greater than seed isoflavone content. Using DiAion HP-20 silica gel and sephadex LH-20 chromatography, pure daidzein was identified in the ether layer, whereas genistin was in the EtOAC fraction.

The effect of Dolichos lablab leave extract on enzyme activities in mice blood was investigated in this study to clarify the new useful application of the plant leaves. There were not significant differences in the enzyme activities in mice blood among treatment fed with the leave extract and non fed control. The feeding treatment with the extract showed a tendency to activity compared to the non fed control. The activities of glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and lactate dehydrogenase in mice blood at the treatment fed with lead and the leave extract were significantly low compared to their activities at the non fed treatment with the extract, respectively. The choline esterase activity was high at the leave extract feeding. The cadmium dietary treatment showed the same result as the lead treatment. In conclusion, the physiological function of the Jebikong leave was significantly in creased when the mice was stressed by the heavy metal intake. Therefore, the plant leave extract would consider the reduction of heavy metal effect.
