  • The electron beam irradiation was applied as a pretreatment of the enzymatic hydrolysis of yellow poplar with doses of 0$\sim$450 kGy. The higher irradiation dose resulted in the more degradation of hardwood biomass not only from carbohydrates but also from lignin. This changes originated from the irradiation resulted in the better response to enzymatic hydrolysis with commercial cellulases (Celluclast 1.5L and Novozym 342). The more improvement on enzymatic hydrolysis by the irradiation was found in the xylan than in the cellulose of yellow poplar.

  • 마늘은 백합과 식물로서 인류의 식생활에서 중요한 역할을 할 뿐 아니라 최근에는 항암작용을 가진 것으로도 알려져 세계적으로 많은 연구가 수행되고 있다. 그러나 같은 백합과 식물인 양파의 경우 과량 섭취시 개에서 용혈성 빈혈이 유발된다는 것은 잘 알려진 사실이지만 마늘의 경우 이러한 부작용에 관한 보고는 전혀 없는 실정이다. 따라서 본 연구에서는 체중 25 kg 이상의 성견을 대상으로 마늘 추출액을 투여한 결과 다음과 같은 성적을 얻었다. 총적혈구수(RBC), 헤모글로빈(Hb)함량, 혈구용적(PCV), 평균적혈구용적(MCV), 평균적혈구혈색소농도(MCHC)는 실험기간 중 유의한(P<0.05) 감소경향을 나타내었다. GSH 함량은 6일째 유의한(P<0.01)증가를 나타내었다. 본 실험 성적의 결과 과량의 마늘 투여시에도 양파에서와 동일한 용혈성 빈혈이 발생되는 것으로 생각된다.

  • In an effort to use plant biotechnology for the production of biopharmaceuticals, pollens collected from lily (Lilium longiflorum) were grown in vitro and transformed with a PCR-amplified 1.7 kb cDNA encoding human tissue plasminogen activator (tPA) using Agrobacterium via a vacuum infiltration process. Western blotting showed that transgenic lily pollen tubes selected on kanamycin for 16 hrs expressed a tPA protein with a size similar to the human standard, suggesting their possible use as a disposable host for rapid foreign protein production.

  • A clone, LCM1, which encodes calmodulin (CaM) was isolated and characterized from monocot lily (Lilium longiflorum Thunb.) plants. The clone is 681 bps and contains the 447 bp coding region, 8 bp leader sequence, 210 bp 3'-untraslated region, and a poly(A) tail. The coding region of 149 amino acids encodes a protein of predicted Mr 17 kD. Comparison of the LCM1 amino acid sequence with other CaMs revealed that the protein is highly conserved among various living organisms. The expression level of calmodulin gene in lily was studied by RNA blot analysis. The LCM1 mRNA was present in all tissues tested. However, a higher level of calmodulin was observed in anther and floral bud. The level of calmodulin mRNA in anther was about 10 times higher than that in anther was about 10 times higher than that in vegetative tissues. The anther preferential expression of CaM in lily is currently investigated in dicot plants.
