Cotton and silk fabrics dyed with brazilein(Caesalpinia Sappan), berberine (Phellodendron Amurense), and shikonin(Lithospermum Erythrorhizon) were stored in the air, in the water, and under the ground for about one year. The change of the color, the flexibility, and the breaking strength were measured at the intervals of few weeks. The results are as follows; 1. The color of the fabrics changed most extensively in the fabrics that were under the ground, then in the order of the ones that were in the water, and in the air. The color of the fabrics changed to the achromatic color over the time. 2. The flexibility change among the dyes was similar. All the fabrics became stiff under the ground and in the water over the storage time. 3. In general, cotton and silk fabrics dyed with berberine showed better strength retention than the fabrics dyed with other substances. 4. The strength retention of cotton fabrics was high in the order of the fabrics which were in the air, in the water, and under the ground. Only minuscule change occurred in the strength of the cotton fabrics. The strength of the fabrics that were in the water and under the ground decreased remarkably after 30 weeks and 20 weeks respectively. 5. The strength retention of silk fabrics was high in the order of the fabrics which were in the air, under the ground, and in the water. In the air, the strength on silk fabrics decreased rapidly after 30 weeks. In the water, the strength of silk fabrics decreased more rapidly than that of the cotton fabrics. Under the ground, the strength retention of silk was higher than that of cotton.

Objectives: This study was evaluated to elucidate the inhibitory potential of Imyosan(IMS) and its components, Phellodendri Cortex(PC: Phellodendron amurense Rupr., Hwangbaek in Korean) and Atractylodis Rhizoma(AR: Atratylodes lancea D.C., Changchool in Korean), on human aortic smooth muscle cells(HASMC) migration and production of matrix metalloproteinase (MMP)-2 and MMP-9 by TNF-${\alpha}$ treatment. Methods: Cytotoxic activity of IMS and its components on HASMC was using 5-(3-caroboxy meth-oxyphenyl)-2H-tetra-zolium inner salt(MTS) assay. Effect of IMS, PC and AR on TNF-${\alpha}$-induced HASMC migration underside of matrigel filter was stained with hematoxylin-eosin. And total number of cells that migrated to the underside of the filter was counted. MMP-2 and MMP-9 activity was evaluated by gelatin zymography assay. Results: The matrigel migration assay showed that IMS effectively inhibited the TNF-${\alpha}$-induced migration of HASMC. Moreover, IMS significantly inhibited MMP-9 activity. Our present study demonstrates that IMS and its components inhibit TNF-${\alpha}$-induced HASMC migration and MMP-9 activity. The inhibitory effect of IMS extract is more potent than that of its component herb extracts. Conclusions: These results provide evidence that IMS has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration.

Berberine은 전통적인 중의약재로 이용되어지는 isoquinoline alkaloid로 황련, 황백과 같은 식물에서 주로 추출되며, 약리효과로는 항암, 항염, 항균과 같은 다양한 효과를 나타내는 것으로 알려져 있다. 그러나 간암세포에서 berberine의 산화적 스트레스에 의한 세포사멸기전에 대해서는 아직 밝혀진 바 없다. 따라서 본 연구는 사람의 간암세포인 HepG2 세포에서 berberien의 세포사멸기전에 reactive oxygen species(ROS)와 MAP kinase의 연관성을 조사하였다. Berberine은 HepG2 세포에서 처리 시간과 농도에 의존적으로 세포독성효과를 보였으며, $LD_{50}$은 berberine(50 ${\mu}M$) 처리 후 48시간에서 관찰 되었고, 세포고사의 특징인 핵의 응축 및 분절, DNA의 분절이 확인되었다. 또한 berberine에 의해 caspase-3, p53, p38 그리고 Bax의 발현이 현저하게 증가된 반면, anti-apoptotic 신호기전인 Bc1-2의 발현은 감소되었다. 이와 더불어 세포 내 nitric oxide(NO)와 ROS의 생성도 증가되었다. 본 연구 결과 HepG2 세포에서 berberine은 산화적 스트레스인 ROS와 NO의 생성을 유발하고 p38 MAP kinase와 p53의 인산화를 유도하였으며 미토콘드리아에서 Bcl-2의 감소와 bax의 증가, caspase-3의 활성을 경유하여 DNA의 손상을 통한 세포고사가 이루어지는 것을 확인 하였다.

The purpose of this study was to investigate the effect of Imyosan on apoptosis in human colorectal cancer HCT116 cells. Phellodendron amurense Rupr. and Atratylodes lancea D.C. compose Imyosan. First of all, to study the cytotoxic effect of methanol extract of Imyosan (IMS-MeOH) on HCT116 cells, the cells were treated with various concentrations of IMS-MeOH and then cell viability was determined by XTT reduction method. IMS-MeOH reduced viability of HCT116 cells in a dose and time-dependent manner. To confirm the induction of apoptosis, the c1eavage of poly ADP-ribose polymerase (PARP), a substrate for caspase-3 and a typical sign of apoptosis, and the activation of caspase-3, procaspase-8 and procaspase-9 were examined by western blot analysis. IMS-MeOH decreased procaspase-3, procaspase-8 and procaspase-9 levels in a dose-dependent manner and induced the clevage of PARP. IMS-MeOH triggered the mitochondrial apoptotic signaling by increasing the release of cytochrome c from mitochondria to cytosol. Furthermore, IMS-MeOH also downregulated the anti-apoptotic Bcl-2 and upregulated the pro-apoptotic-Bax. Therefore, these results suggest that IMS-MeOH induced HCT1l6 cell death through the mitochondrial pathway. To explore whether the activities of caspases was required for induction of apoptosis by IMS-MeOH, caspase-3, -8, -9 activity measured by using substrates, respectively. IMS-MeOH increased caspase-3, -8, -9 activity. Co-treatment with inhibitors of caspase-3, -8, -9 and IMS-MeOH significantly blocked IMS-MeOH-triggered apoptosis in HCT1l6 cells. These results suggest that IMS-MeOH induces caspases-mediated apoptosis.
