  • 독성약물에 의한 급성신부전시 세뇨관세포의 물질 재흡수 장애에 대한 단삼(丹參) 추출액의 효과를 조사하였다. 토끼에 수은(HgCl2)을 10 mg/kg되게 피하 주사하여 급성신부전을 유발하였고, 단삼(丹參) 추출액의 효과는 수은을 주사하기 전 7일 동안 0.05% 액(液) 0.3 g/kg 용량을 경구 투여하여 관찰하였다. 수은을 주사하기 전 24시간 동안 요와 혈액을 채취하여 신장기능을 측정하여 대조기간(basal period)의 값으로 하였고, 수은을 주사한 후 24시간 동안 요와 혈액을 얻어 수은에 의한 신장기능 변화를 평가하였다. 수은을 처리한 후 사구체여과율이 대조값에 비해 감소하였고, 혈청내 creatinine 농도가 증가하였다. 이러한 결과들은 수은이 급성신부전을 유발하였음을 가리킨다. 수은을 처리한 동물에서 포도당 및 인산의 배설분율이 증가하였고, 이러한 변화는 brush-border membrane에서 물질의 이동장애와 Na-pump 활성의 감소에 기인하였다. 수은을 주사한 동물의 신장피질 절편에서 유기이온인 PAH와 TEA 이동이 억제되었다. 토끼의 신장조직에서 지질의 과산화가 수은을 주사한 후 증가하였다. 단삼(丹參) 추출액을 전 처리한 후 수은을 주사한 경우 수은에 의해 유발된 사구체여과율의 감소와 혈청내 creatinine 농도 증가 현상이 유의하게 완화되었다. 수은에 의한 세뇨관에서 물질의 재흡수 장애가 단삼(丹參) 추출액의 전처리에 의해 방지되었다. 단삼(丹參) 추출액은 수은에 의한 지질의 과산화를 억제하였다. 수은에 의한 급성신부전은 항산화제로 잘 알려진 DPPD에 의해 방지되었다. 이상의 결과를 종합하면 생체실험결과 수은에 의한 급성신부전의 유발과정에 지질의 과산화가 중요한 역할을 할 가능성을 보이고 있고, 단삼(丹參) 추출액은 수은에 의한 급성신부전을 방지하는 효과를 가지고 있으며, 그 효과는 단삼(丹參)의 항산화작용에 기인(起因)할 가능성이 많다.

  • 목적 : 이전 연구에서 단삼 추출액이 강력한 항산화 작용이 있음을 확인한 바 있어 단삼 추출액이 신장세뇨관 세포에서 oxidant에 의한 세포사망 및 DNA 손상을 방지하는 지를 조사하고 이러한 효과가 지질의 과산화를 억제하는 효과에 기인하는 지를 시험하였다. 방법 : 신장 근위세뇨관 세포 유래 세포주인 opossum kidney (OK)세포를 이용하여 세포 사망은 frypan blue exclusion방법을 이용하여 평가하였고, DNA손상 정도는 double stranded DNA의 파괴를 측정하여 평가하였다. Oxidant 약물 모델로는 $H_2O_2$를 사용하였다. 결과 : $H_2O_2$는 적용시 간과 농도에 비례하여 세포 사망을 유도하였다. 단삼 추출액은 0.05% 농도에서 $H_2O_2$에 의한 세포사망 및 DNA 손상을 방지하였다. 이러한 방지효과는 $H_2O_2$ 제거 효소인 catalase와 철 착염제인 deferoxamine에 의해서도 나타났다. 그러나 강력한 항산화제인 DPPD는 $H_2O_2$에 의한 세포 사망이나 DNA손상을 방지하지 못하였다. $H_2O_2$는 세포내 ATP 농도를 감소시켰으며. 이러한 감소는 poly (ADP-ribose) polymerase억제제인 3-aminobenzamide에 의해 방지되었으나 단삼 추출액에 의해서는 영향을 받지 않았다. 3-aminobenzamide는 $H_2O_2$에 의한 세포 사망을 방지하였다. $H_2O_2$는 지질의 과산화를 증가시켰으며, 이러한 변화는 단삼 추출액과 DPPD에 의해 방지되었다 결론 : OK 세포에서 $H_2O_2$에 의한 세포사망과 DNA 손상에는 지질의 과산화가 중요한 역할을 하지 않으며, 단삼 추출액의 $H_2O_2$에 의한 세포 사망과 DNA 손상 방지 효과는 항산화 작용이 아닌 다른 기전에 기인하는 것으로 사료된다.

  • 목적:반응성산소기들은 장관에서 여러 종류의 질병의 발생과 관련을 가지고 있는 것으로 알려져 있어, 이들에 의한 세포손상을 방지하는 약물의 개발은 시급한 실정이다. 본 연구에서는 항산화작용을 가진 약재로 보고 된 단삼추출액이 장관상피세포에서 $H_2O_2$에 의한 세포손상을 방지할 수 있는 지를 조사하고자 하였다. 방법:장관상피세포로는 사람의 소장상피세포에서 유래한 배양세포주인 Caco-2세포를 이용하였고, 세포손상 정도는 trypan blue exclusion assay를 통해 평가하였고, 지질의 과산화는 그 산물인 malondialdehyde의 량을 측정하여 산정하였다. 결과: $H_2O_2$는 처리 시간 및 농도에 비례하여 세포손상을 유발하였으며, 이러한 효과는 단삼추출액에 의해 농도의존적으로 방지되었다. $H_2O_2$에 의한 세포소상은 $H_2O_2$제거제인 catalase와 철착염제인 deferoxamine에 의해 방지되었으나 항산화제인 N,N-diphenyl-p-phenylenamine(DPPD)에 의해 영향을 받지 않았다. $H_2O_2$는 지질의 과산화를 증가시켰으며, 이러한 효과는 단삼추출액과 DPPD에 의해 억제되었다. 단삼추출액은 $H_2O_2$에 의한 세포내 ATP 고갈을 방지하였다. $H_2O_2$는 DNA 손상을 일으켰으며, 이러한 효과는 단삼추출액, catalase 및 deferoxamine에 의해 방지되었으나, DPPD에 의해서는 변화되지 않았다. 결론 : 이상의 결과를 종합하면 단삼추출액은 장관상피세포에서 $H_2O_2$에 의한 세포손상을 방지하며, 이러한 효과는 항산화작용이 아닌 다른 작용기전에 기인할 것으로 생각된다. 또한 본 연구의 결과는 $H_2O_2$가 장관상피세포에서 지질의 과산화를 유발하여 세포손상을 일으키지 않음을 가리킨다.

  • This study was carried out to determine if Salviae Radix extract (SRE) exerts protective effect against alterations in membrane transport function in rabbits with rhabdomyo lysis-induced acute renal failure. Acute renal failure was induced by intramuscular administration of glycerol (50%, 10 ml/kg). GFR in the glycerol-injected animals was reduced to 11% of the basal value and the fractional $Na^{+}$ excretion was increased to 7.8-fold, indicating generation of acute renal failure. When animals received SRE pretreatment for 7 days prior to glycerol injection, such changes were significantly attenuated. The fractional excretion of glucose and phosphate was increased more than 43-fold and 27-fold, respectively, in rabbits treated with glycerol alone. However, they were increased to 17-and 4.3-fold, respectively, in SRE-pretreated rabbits, and these values were significantly lower than those in rabbits treated with glycerol alone. Uptakes of glucose and phosphate in purified isolated brush-border membrane, the $Na^{+}-K^{+}-ATPase$ activity in microsomal fraction, and cellular ATP levels all were reduced in rabbits treated with glycerol alone. Such changes were prevented by SRE pretreatment. Uptakes of organic ions, PAH and TEA, in renal cortical slices were inhibited by the administration of glycerol, which was prevented by SRE pretreatment. Pretreatment of an antioxidant DPPD significantly attenuated the increase in the fractional excretion of glucose and phosphate induced by rhabdomyolysis. These results indicate that rhabdomyolysis causesimpairment inreabsorption of solutes in the proximal tubule via the generation of reactive oxygen species, and SRE pretreatment may provide the protection against the rhabdomyolysis-induced impairment by its antioxidant action.

  • The antibacterial effect of fish diet soaked in the extract of Salvia miltiorriza was tested to determine its levels of antibacterial activity, minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC). The extract showed strong activity against gram positive bacteria, but was weak against gram negative bacteria. Concentration levels of 13.4~40.3 and 67.2~403.0 $\mu\textrm{g}$/ml were determined as the MIC and MBC, respectively. However, levels above 403.0 $\mu\textrm{g}$/ml was neither bacteriostatic nor bactericidal against Edwardsiella tarta, a gram negative strain. The fish diet, soaked in the extract of Salvia miltiorriza, inhibited the growth of all strains of Streptococcus genus and Vibrio anguillarum. The relationship formula between weight of fish diet and Salvia miltiorriza extract absorbed into the fish diet was Y=2.4953X+3.3276 ($R^2$= 0.9999). The antibacterial activity of the fish diet, soaked in the extract, was stable from 10 to 35$^{\circ}C$ during the storage period of 28 days.

  • In this work, analytical HPLC was utilized to obtain Tanshinone IIA (TIIA) from Salvia Miltiorrhiza Bunge (SMB). The optimum operating conditions were experimentally determined to analyze the TIIA in the pretreated extract. SMB was extracted with the various organic solvents of methanol, ethyl acetate, and ethanol, then the extract was analyzed to compare the amount of TIIA. From the results, the methanol showed the best extraction efficiency of TIIAd. The analysis by $C_{18}$ column was performed. The mobile phase was composed of methanol and water, and the isocratic elution mode was mainly applied. $2.154{\mu}g$ of TIIA/mg of SMB powder was extracted with methanol.

  • This study was performed to evaluate the antitumor activities of water and ethanol (EtOH) extract of Salvia miltiorrhiza in vitro and in vivo. The proliferation of the human hepatoma (HepG2), rectum cancer (HRT-18) and colon cancer (HT-29) cells was inhibited by administration of extracts in a dose-dependent manner. Particularly, EtOH extract inhibited proliferation of the cells more effectively than water extract did. The morphology of cells induced by EtOH extract was characterized by reduction of cell size and deformatin. Oral administration of the EtOH extract (3 mg/head) to tumor-bearing mice inhibited the tumor (sarcoma-180) growth by 35% and prolonged their survival rate by 61%. The EtOH extract was shown to be nontoxic at 37.5% mg/head/day on the acute toxicity test. These studies suggest that the EtOH extract of Salvia miltiorrhiza may have antitumor activity in vitro and in vivo.

  • Dansam (Salvia miltiorrhiza Bunge) is a perennial plant that belongs to the Labiatae family and is characterized by red pigment found in the epidermis of its roots. Research on the dyeability of Dansam extract was performed with repeated trials under various conditions such as temperature, time, and mordant treatment. Silk fabrics were dyed with Dansam extract and mordanted with various agents such as Al, Fe, Cu, and Sn to evaluate the dyeability and functionality of Dansam extract; subsequently, the K/S value and the change of surface color were analyzed using a colorimeter. In addition, the dyeability of dyed fabrics (such as color fastness to washing, dry cleaning fastness, rubbing fastness and light fastness) and functionality (such as antibacterial activity and deodorization) were analyzed. The surface colors of all dyed fabrics were recorded and the results showed the presence of mostly YR series of colors; in addition, a GY color series appeared in the Fe pre-mordants of the silk fabric. The highest K/S values were recorded in Fe post-mordants. The washing fastness were Level 3 and Level 4; in addition, the dry-cleaning fastness showed excellent results at Level 4 and Level 5. The rubbing fastness was satisfactory at Level 3 and Level 4 and the light fastness was satisfactory at Level 4. The results of the measurements (that pertained to the antibacterial activity of fabrics dyed with Dansam extract) showed a 99.9% bacteria reduction rate of Staphylococcus aureus and Klebsiella pneumoniae. In regards to deodorization ability, dyed fabrics were found to have higher deodorization rates than those not dyed. The dyed fabric demonstrated exceptional deodorization qualities.

  • Objectives: The aim of this study was to determine the effects of Salvia miltiorrhiza (SM) extract in urethane-induced lung tumorigenesis in A/J mice. Methods : We examined change of body weight, histological, apoptosis, immunohistochemical and gene expression of cyclooxygenase (COX-2) in lung tumors. Mice were divided into 3 groups: normal, saline, and experimental group administered SM extract after injection with urethane. Results : Histological observation showed shrunken alveoli in the control group, but recovered from damage in the SM extract administered group. The COX-2 positive materials were observed in the smooth muscle of terminal bronchiole and alveoli from the control group, but these positive materials decreased in the SM extract treatment group. The results of electron microscopical observation, dilated capillary and degenerated endothelia were observed in the control group. The apoptotic nuclei increased more in the control group compared with the normal and SM extract administered groups. Serial sections of the whole lung showed solid and papillary tumors. The size and number of tumors decreased in the SM groups compared with the control groups. Conclusions : These results suggest the possibility that SM may exert an anti-tumor effect on urethane-induced lung tumorigenesis.
