  • The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling moleculesthrough suppression both mitogen-activated protein kinases(MAPK) and nuclear factor-kappa B ($NF-{\kappa}B$) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of anti-oxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazine.

  • With the recent rapid improvement in the standards of life and westernization of dietary lifestyles, the consumption of high-calorie diets such as high-fat and high-protein red meat and instant foods has increased, while less vegetables containing dietary fiber are consumed. In addition to that, stress, erroneous dietary behaviors, and contaminated environments are linked to the risk of developing ulcerative colitis, which is on the rise. Another cause of ulcerative colitis is that involve laxative abuse, including repeated, frequent use of laxatives, and include such conditions as deteriorated bowel function, irritable bowel syndrome, diarrhea, intestinal inflammation, etc. The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of antioxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazine.

  • Tamoxifen, a nonsteroidal estrogen receptor (ER) antagonist, is used routinely as a chemotherapeutic agent for ER-positive breast cancer. However, it is also causes side effects, including retinotoxicity. The retinal pigment epithelium (RPE) has been recognized as the primary target of tamoxifen-induced retinotoxicity. The RPE plays an essential physiological role in the normal functioning of the retina. Nonetheless, potential therapeutic agents to prevent tamoxifen-induced retinotoxicity in breast cancer patients have not been investigated. Here, we evaluated the action mechanisms of sulfasalazine against tamoxifen-induced RPE cell death. Tamoxifen induced reactive oxygen species (ROS)-mediated autophagic cell death and caspase-1-mediated pyroptosis in RPE cells. However, sulfasalazine reduced tamoxifen-induced total ROS and ROS-mediated autophagic RPE cell death. Also, mRNA levels of tamoxifen-induced pyroptosis-related genes, IL-1β, NLRP3, and procaspase-1, also decreased in the presence of sulfasalazine in RPE cells. Additionally, the mRNA levels of tamoxifen-induced AMD-related genes, such as complement factor I (CFI), complement factor H (CFH), apolipoprotein E (APOE), apolipoprotein J (APOJ), toll-like receptor 2 (TLR2) and toll-like receptor 4 (TLR4), were downregulated in RPE cells. Together, these data provide novel insight into the therapeutic effects of sulfasalazine against tamoxifen-induced RPE cell death.

  • Sulfasalzine is a widely administered drug against inflammatory-based disorders in human. However several cases of liver injury are associated with its administration. There is no stabilized safe protective agent against sulfasalazine-induced liver injury. Current investigation was designed to evaluate if N-acetylcysteine (NAC) and dithioteritol (DTT) as thiol reducing agents and/or vitamins C and E as antioxidants have any protective effects against sulfasalazine-induced hepatic injury in an ex vivo model of isolated rat liver. Rat liver was canulated and perfused via portal vein in a closed recirculating system. Different concentrations of sulfasalazine and/or thiol reductants and antioxidants were administered and markers of organ injury were monitored at different time intervals. It was found that 5 mM of sulfasalazine caused marked liver injury as judged by rise in liver perfusate level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) (p < 0.05). A significant amount of lipid peroxidation and hepatic glutathione depletion were detected in drug-treated livers, accompanied with significant histopathological changes of the organ. Administration of NAC ($500{\mu}M$), DTT (${400\mu}M$), Vitamin C ($200{\mu}M$), or vitamin E ($200{\mu}M$) significantly alleviated sulfasalazine-induced hepatic injury in isolated perfused rat liver. The data obtained from current investigation indicate potential therapeutic properties of thiol reductants and antioxidants against sulfasalazine-induced liver injury.

  • Most of the axons in the vertebrate nervous system are surrounded by a lipid-rich membrane called myelin, which promotes rapid conduction of nerve impulses and protects the axon from being damaged. Multiple sclerosis (MS) is a chronic demyelinating disease of the CNS characterized by infiltration of immune cells and progressive damage to myelin and axons. One potential way to treat MS is to enhance the endogenous remyelination process, but at present there are no available treatments to promote remyelination in patients with demyelinating diseases. Sulfasalazine is an anti-inflammatory and immune-modulating drug that is used in rheumatology and inflammatory bowel disease. Its anti-inflammatory and immunomodulatory properties prompted us to test the ability of sulfasalazine to promote remyelination. In this study, we found that sulfasalazine promotes remyelination in the CNS of a transgenic zebrafish model of NTR/MTZ-induced demyelination. We also found that sulfasalazine treatment reduced the number of macrophages/microglia in the CNS of demyelinated zebrafish larvae, suggesting that the acceleration of remyelination is mediated by the immunomodulatory function of sulfasalazine. Our data suggest that temporal modulation of the immune response by sulfasalazine can be used to overcome MS by enhancing myelin repair and remyelination in the CNS.

  • 본 연구는 인체에 유익한 효과가 있고 부작용 없이 장기간 안전하게 사용할 수 있으며 표준치료제인 설파살라진과 비교하여 열처리된 무 추출물의 궤양성 대장염증의 예방에 탁월한 효과가 있는지 알아보았다. 쥐에 덱스트란나트륨설페이트(DSS)로 유도된 UC에 대한 설파살라진 투여군과 열처리된 무추출물 투여군에 대해 약리효능의 비교 평가를 알아보았다. Balb/c 마우스는 7일동안 식수에 5 % DSS를 투여하여 대장염을 유도하였다. DSS+ sulfasalazine(30 mg/kg), IV-DSS + sulfasalazine(60 mg/kg), 5-DSS +, V-DSS + 설파살라진(30 mg/kg) + 무우 엑기스 혼합물(30 mg/kg) (SRE). DSS 처리된 마우스는 심한 피의 설사 및 체중 감소와 같은 인간 UC와 유사한 증상을 보였다. 설파살라진 뿐만 아니라 SRE보충은 결장길이와 점막염증 침투를 억제하였다. 또한 SRE 치료는 MAPK와 nuclear factor-kappa B(NF-${\kappa}B$) 신호전달 경로를 억제함으로써 전염증 신호분자의 발현을 현저히 감소 시켰으며 결장의 세포 사멸을 예방하였다. 또한, SRE 투여는 SOD 및 카탈라아제를 포함한 항산화 효소의 상향 조절을 의미있게 만들었다. 이번 연구 결과는 열처리된 무추출물과 설파살라진의 병용 투여가 sulfasalazin 표준과 매우 유사한 염증과 세포사멸의 억제. 열처리된 무추출물은 궤양성 대장염 유발에 의한 대장의 길이 감소와 조직학적 변화에 의한 대장 길이의 감소나 조직학적 변화를 효과적으로 억제 하였다.

  • 설파살라진은 1941년 최초로 합성된 이후, 류마티스 관절염, 궤양성 대장염 및 크론병을 치료하는 데 사용되는 질병 변형 항 류마티스 약물-비 생물제제 (아미노살리실산 유도체)이다. 1950년 미국에서 의약품으로 승인된 이후 다양한 염증성 질환의 치료제로 사용되고 있으나 이 약물의 작용기전은 아직 명확하게 밝혀지지 않고 있다. 본 연구에서는 설파살라진이 염증반응을 조절하는 주요 면역세포인 대식세포의 세포생존, 세포사멸 및 세포주기 진행에 어떠한 영향을 미치는지를 마우스 대식세포인 RAW264.7 세포를 이용하여 조사하였다. 세포생존에 미치는 설파살라진의 영향을 측정한 결과 농도의존적으로 RAW264.7 세포의 생존을 억제하였다. 이러한 세포생존의 억제가 세포사멸에 기인한 것인지를 확인하기 위해 Annexin-V로 염색한 결과 0.25 mM 이상의 농도에서 Annexin-V 양성세포가 유의적으로 증가하였다. 또한 0.25 mM 이상의 농도에서 G0/G1기에서 유의적으로 세포주기 정체를 유도하는 것을 확인할 수 있었다. G0/G1기를 조절하는 주요 단백질의 발현을 확인한 결과 설라살라진의 처리는 RAW264.7 세포에서 CDK의 억제제인 p21과 p27의 단백질 발현을 유의적으로 증가시켜 설라살라진에 의한 G0/G1기의 정체는 p21과 p27에 기인하는 것으로 사료된다. 염증성 궤장염이나 류마티스 관절염과 같은 염증성 질환에서 설라살라진이 대조약으로 빈번하게 사용되어지고 있음에도 불구하고 대식세포에 미치는 영향에 대한 연구가 매우 제한적이어서 본 연구의 결과가 질병치료제로서의 설파살라진의 이용에 기초적인 정보를 제공할 수 있을 것이라 판단된다.

  • 구강편평태선은 면역매개성 반응으로 유발되는 만성염증질환으로 정의할 수 있으며 그 정확한 원인은 아직 밝혀지지 않은 상태이다. 일반적으로 스테로이드를 이용한 국소적 또는 전신적 치료를 시행하고 있으나 스테로이드 치료에 반응이 없는 환자의 경우에는 치료가 힘들다. Sulfasalzine은 염증성 장질환을 치료하기 위한 약물로 선택되고 있고 류마티스성 관절염에서도 치료제로 사용하고 있다. 염증성 장질환과 구강편평태선에서 발병기전을 살펴보면 공통적인 부분이 많이 발견된다. 전신적으로 투여시 나타나는 부작용을 최소화하고 접근의 편이성을 위하여 Sulfasalzine을 구강편평태선에 국소 도포의 형태로 시도하였으며, 본 연구에서는 성공적으로 치료한 2 치험례를 소개하였다. 첫번째 증례에서는 8주간의 도포(30mg/5ml, 하루3번) 후 증상이 완화되었으며, 두번째 증례에서는 15주간의 도포 후 증상이 완화되었다. 두 증례 모두 스테로이드에 치료반응이 없었던 환자였으며 sulfasalazine 도포 후 현재까지 증상이 완화된 상태로 지내고 있다. 따라서 Sulfasalazine은 구강편평태선환자에서 치료약물로 선택될 수 있다는 결론을 얻었다.

  • Background : Sulfasalazine for treating ulcerative colitis has a clinical limitation due to its adverse effects. This case is about a patient with ulcerative colitis who could not tolerate sulfasalazine and was improved by Do-che decoction-based Korean medicine. Method and Results : Purulent and bloody diarrhea more than 20 times a day, mild fever, chilling and tenesmus were main symptoms of this patient who was diagnosed as ulcerative colitis 10 years ago. Do-che decoction-based Korean medicine which was recommended for purulent and bloody diarrhea in Dong-Ui-Bo-Gam, the classic literature of Traditional Korean Medicine was given to the patient for more than 1 month. After treatment, the frequency of purulent and bloody diarrhea, tenesmus and fever was decreased remarkably, and C-reactive protein, erythrocyte sedimentation rate, white blood cell count and maximum temperature also dropped to the normal range. Conclusion : Do-che decoction-based Korean medicine has a potential effect and may be a alternative therapeutic option in patients with ulcerative colitis who cannot tolerate sulfasalazine due to its adverse effects.
