on IL-1β-induced secretion and proteolytic activity of MMP-3 were investigated using western blot analysis and casein zymography, respectively. The effect of oleanolic acid on in vivo MMP-3 protein production was also examined, after intra-articular injection to the knee joint of rat. The results were as follows: (1) oleanolic acid inhibited the gene expression of MMP-3, MMP-1, MMP-13, ADAMTS-4, and ADAMTS-5, but increased the gene expression of type II collagen; (2) oleanolic acid reduced the... -

using zymography were measured. Clinical conditions of the LT, HT, and PC groups were significantly improved after 6 weeks. In zymographic evaluations, gelatinolytic and caseinolytic activities were suppressed in LT, HT, and PC groups but not in the NC group. The results suggest that ALH-L1005 could be an effective agent for clinical prevention and treatment of periodontitis by inhibiting the gelatinase and collagenase activities, which can detach periodontal ligaments from alveolar bone. -
Fibrin 용해 균주의 분리 및 특성
한국생물공학회 한국생물공학회지 1999, Vol.14 No.1 103-108 (6 pages)
혈전 용해효소를 생산하는 미생물을 탐색하기 위하여 장류 및 토양사료로부터 미생물을 분리하여 그 중 fibrin 용해활성이 높고 기질특이성이 우수한 S7-l6 균주를 선발하였다. 선발된 미생물은 Gram 양성의 간균으로 운동성이 있고, catalase 양성이었으며 포자를 형성하는 것으로 관찰되어 BClcilius sp. S7-16으로 명명하였다. $alpha$cill$mu$ sp S7-16의 효소생산 조건을 검토한 결과,0.5% (w/v) polypeptone, 0.5% (w/v) yeast extract, 0.3% (w/v) NaCI, 0.l%(w/v) $KH_2P0_4$, 0.3% (w/v) $KH_2P0_4$, 0.01% (w/v)...
