  • Obesity has become one of the main public health problems. Saussurea lappa (Asteraceae), syn Aucklandia lappa and Saussurea costus, is a well-known herbal medicine that has been used for treating various ailments, such as inflammatory and gastrointestinal diseases. The present study examined the anti-obesity effect of S. lappa extract (SLE) in 3T3-L1 adipocytes and high fat diet (HFD)-induced obese mouse model. SLE significantly inhibited the differentiation from preadipocytes to adipocytes of cultured 3T3-L1 in dose-dependent manner. In addition, SLE significantly decreased the body weight gain and the food efficiency ratio of mice fed HFD during 9 weeks. Further study must be performed for the pharmacological mechanism and safety of SLE as well as the identification of active compound in SLE. Our results revealed that S. lappa suppresses the adipogenesis in cultured cells and the obesity in rodent models. Therefore, S. lappa may be useful toward the development of new potent anti-obesity drugs.

  • This study was conducted to evaluate the antioxidant and antimicrobial activities of lyophilized extracts of scallions (Allium fistulosum L., SLE), garlic (Allium sativum, GLE), and gold kiwi (Actinidia chinensis, GKE) and their effects on the quality of chicken breast meat inoculated with L. monocytogenes during storage for 9 days at $4^{\circ}C$. The lowest minimum inhibitory concentration and minimum bactericidal concentration (25 and 100 mg/mL, respectively) against L. monocytogenes were observed for SLE and GLE, respectively. GKE had the lowest half-maximal inhibitory concentration ($IC_{50}$) for 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activity (5.06 mg/mL). The pH values of meat inoculated with L. monocytogenes and dipped in 1% SLE (LSLE), 1% GLE (LGLE), or 1% GKE (LGKE) were lower than that of the control on day 3 of storage (p<0.05). The initial population of L. monocytogenes in meat was 4.95-5.01 Log CFU/g. However, the population in the LSLE (5.73 Log CFU/g) was lower than that in the control (6.23 Log CFU/g) on day 5 (p<0.05). The volatile basic nitrogen value of the LSLE (19.90 mg/100 g) was lower than that of the control (24.38 mg/100 g) on day 7 (p<0.05). Moreover, treatment with SLE resulted in the maintenance of meat quality and reduced the population of L. monocytogenes on the meat. Thus, SLE may be used as an alternative natural and environmentally friendly sanitizer for reducing L. monocytogenes contamination in the chicken meat industry.

  • Objectives: Systemic lupus erythematosus (SLE) or lupus patients usually experience various physical and psychological challenges. Since the coronavirus disease 2019 pandemic, these challenges have become even harsher. Using the participatory action research approach, this study evaluated how an e-wellness program (eWP) impacted SLE-related knowledge and health behaviors, mental health, and quality of life among lupus patients in Thailand. Methods: A 1-group, pretest-posttest design study was conducted among a purposive sample of lupus patients who were members of Thai SLE Foundation. The 2 main intervention components were: (1) online social support, and (2) lifestyle and stress management workshops. Sixty-eight participants completed all the study requirements, including the Physical and Psychosocial Health Assessment questionnaire. Results: After being in the eWP for 3 months, participants' mean score for SLE-related knowledge increased significantly (t=5.3, p<0.001). The increase in sleep hours was statistically significant (Z=-3.1, p<0.01), with the percentage of participants who slept less than 7 hours decreasing from 52.9% to 29.0%. The percentage of participants reporting sun exposure decreased from 17.7% to 8.8%. The participants also reported significantly lower stress (t(66)=-4.4, p<0.001) and anxiety (t(67)=-2.9, p=0.005). The post-eWP quality of life scores for the pain, planning, intimate relationship, burden to others, emotional health, and fatigue domains also improved significantly (p<0.05). Conclusions: The overall outcomes showed promising results of improved self-care knowledge, health behaviors, mental health status, and quality of life. It is recommended that the SLE Foundation continues to use the eWP model to help the lupus patient community.

  • 목 적: SLE에서는 진단 당시 및 경과 중에 약 15-20%에서 혈소판 감소가 발생하며, 5-16%에서는 혈소판 감소증이 첫 임상증상으로 발생할 수 있으므로 소아 ITP와 SLE와의 연관성이 강력히 제기되고 있다. 한편 항핵항체는 여러 자가면역질환의 선별검사로 주로 이용되고 있는데, 특히 자가면역질환의 임상증상이 발현되기 수개월 혹은 수년 전에 발현될 수 있다. 따라서 저자들은 소아 ITP로 진단된 환자들에서 항핵항체 검사의 양성률 및 임상적 의의를 조사하고자 본 연구를 시작하였다. 방 법: 2003년 1월부터 2006년 12월까지 부산대학교병원 소아청소년과에서 급성 ITP로 진단 받고, 진단 당시에 항핵항체 검사를 시행하였던 77예의 환아를 대상으로 하였다. 항핵항체 검사는 정량 및 정성 검사를 시행하였고, 1:40 이상을 양성으로 판정하였다. 항핵항체 검사 상 양성인 환자들은 1년 이상 역가를 주기적으로 추적관찰 하였다. 결 과: 1) 진단 당시 항핵항체 검사를 시행한 77예의 ITP 환자 중 남아는 38예(49.4%), 여아는 39예(50.5%)였으며, 평균 연령은 4.5세였고, 16예(20.8%)에서 항핵항체 검사 상 양성을 보였다. 2) 항핵항체 양성인 군에서 항핵항체의 정량 역가의 분포는 1:80-1:1,280으로 1:640이 16명 중 5명(30.7%)으로 가장 많았고, 항핵항체의 형은 homogeneous 형이 16명 중 6명(37.5%)으로 가장 많았다. 3) 항핵항체가 양성인 군의 평균 연령은 9.3세로 음성인 군의 3.3세에 비해 진단 당시 평균 연령이 의미 있게 높았다(P<0.05). 4) 항핵항체가 음성인 군의 남녀비는 비슷하였던 반면 항핵항체가 양성인 군은 여아가 81.3%로 현저히 높았다(P<0.05). 5) 진단 당시 혈소판 정중값은 항핵항체 양성군에서는 $18,400/{\mu}L$, 음성군에서는 $21,800/{\mu}L$으로 두 군 사이에 의미 있는 차이가 없었다. 6) 진단 당시 항핵항체의 역가 및 형은 만성 ITP 및 SLE로의 진행과 의의있는 관련이 없었다. 7) 급성 ITP 진단 당시 항핵항체 양성이었던 환자 중 1명이 추적관찰 41개월 후 SLE로 최종 진단되었다. 결 론: 소아 급성 ITP 환자에서 ANA 양성인 경우가 비교적 흔한 것으로 나타났으며, 만성 ITP와 SLE로의 진행에 대한 연관성은 더 많은 환자를 대상으로 한 연구를 통하여 밝혀져야 할 것이다.

  • Systemic Lupus Erythematosus(SLE) is a autoimmune disease characterized by combined symtoms of malar rash, discoid rash, neuropsychiatric disorder, renal disorder, hematologic disorder, photosensitivity immunologic disorder, oral ulcer, anti-nuclear antibody, arthritis, pleuritis and pericarditis, etc. Multiple genetic or environmental causes are supposed to facilitate antiboby production to autoantigen such as ds-DNA, histone, phospholipid, red blood cell, platelet, etc. And defective complementary system fail to remove autoantigen-antibody complex, which deposit in multiple organs and result in inflammatory damages. SLE does not correctly correspond to any specific category of oriental medicine. But, accoring to previous reports, it can be controlled by herb medications used differently patients-to-patients. So we are to report this one SLE case being successfully controlled by classic corticosteroids with herb medications based on oriental diffrential diagnosis of symptoms and signs.

  • Objective : The main purpose of this study was to evaluate the effect of Jasinwhalhyul-tang (Zishenhuoxue-tang, JWT) on MRL/MpJ-Ipr/Ipr mouse model with systemic lupus erythematosus. Methods: The effect of JWT on MRL/MpJ-Ipr/Ipr mice that have autoimmune disease similar to SLE in humans was evaluated after JWT per oral in the present study. Mice were administered with Jasinwhalhyul-tang (Zishenhuoxue-tang, JWT) (80 or 400mg/kg) or distilled water for control group from experimental week 10 for 22 weeks. Results : The amount of erythematosus skin lesion and proteinuria were significantly decreased. The size and weight of cervical lymph nodes and spleen were significantly reduced. The ratio between activated $CD3^+CD69^+$ T-cells and undifferentiated $CD3^+CD4^-CD8^-$ T-cells in lymph nodes, spleen and kidney was effectively reduced. The gene expression of TGF-$\beta$ in spleen and kidney was increased. The amount of anti-dsDNA IgG in blood was decreased. The gene expression of TGF-$\beta$ in normal mouse spleen cells was increased depending on concentration by treatment of with T cell stimulating agent. In the histological examination of skin and kidney, the amount of infiltration of immune cells involved in the inflammatory response was decreased. Conclusions : According to the above results, JWT should be considered as an applicable therapeutic agent to SLE in clinical practice. Further research is required to investigate other efficacies of JWT on SLE.
