Objectives This study was performed to investigate the effects of Bujasasim-tang ethanol extract (BST) on oxidative stress, inflammation and osteoarthritic rat model. Methods To ensure safety of BST, heavy metal levels were measured and cytotoxicity test was done. In vitro, To evaluate antioxidative effects of BST, total phenolic contents, 1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging activity, reactive oxygen species (ROS) levels were measured. Also, to evaluate anti-inflammatory effects of BST treated group, total nitric oxide (NO) and pro-inflammatory cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) levels were measured in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In vivo, We injected MIA $50{\mu}l$ (60 mg/ml) into knee joints of rats to induce osteoarthritis. Rats were divided into total 3 groups (normal, control, BST treated group, each n=7). Normal group was not treated at all without inducing osteoarthritis and taken normal diet. Control group was induced osteoarthritis by MIA and taken with 2 ml of distilled water once a day for 4 weeks. BST treated group was induced osteoarthritis by MIA and taken BST 2 ml (200 mg/kg/mouse) once a day for 4 weeks. We evaluated dynamic weight bearing with the Incapacitance Test Meter. At the end of experiment, the rats were sacrificed to observe the functions of liver and kidney, changes of WBC, neutrophil, lymphocyte, monocyte levels in blood, to evaluate the levels of pro-inflammatory cytokines, tissue inhibitor of metallopreteinases-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9), prostaglandin $E_2$ ($PGE_2$), leukotriene $B_4$ ($LTB_4$) within serum. We observed change of articular structures by Hematoxylin & Eosin (H&E), safranin-O staining method and measured amount of cartilage by micro CT-arthrography. Statistical analysis was done by unpaired student's t-test with significance level at p<0.05 in SPSS 11.0 for windows. Results 1. Safety of the BST was identified. 2. AST, ALT, BUN, creatinine levels of BST treated group were within normal limit. In vitro, 1. DPPH and ABTS free radical scavenging activities of BST showed dose-dependent increase. 2. ROS production were significantly decreased. 3. Total nitric oxide (NO) and IL-$1{\beta}$ production were decreased. 4. IL-6 and TNF-${\alpha}$ production were significantly decreased. In vivo, 1. Weight bearing ability was significantly increased. 2. WBC, neutrophil, lymphocyte, monocyte levels in blood were decreased. 3. IL-$1{\beta}$ and TNF-${\alpha}$ levels in serum were significantly decreased. and the IL-6 level was decreased. 4. TIMP-1, MMP-9, $LTB_4$, $PGE_2$ levels in serum were significantly decreased. 5. Cartilage volume of BST treated group was significantly increased. Also changes of cartilage, synovial membrane, fibrous tissue were suppressed. Conclusions The results obtained in this study Bujasasim-tang have effects of antioxidative, anti-inflammatory, relieve pain and protection of cartilage. Therefore we expect that Bujasasim-tang is effective treatment for osteoarthritis.

Objectives This study was intended to clarify the anti-inflammation and anti-oxidation effects of gamikyejakjimo-tang herbal acupuncture (GKHA) for osteoarthritis. Methods Osteoarthritis was induced by injection of MIA into right knee joint cavities of rats. Rats were divided into a total of 4 groups (n=8). The 4 groups were normal group, control group, positive comparison group and expeimental group. Indomethacin and GKHA were medicated for a total of 4 weeks. After that, functions of liver and kidney by AST, ALT, creatinine, BUN, DPPH and ABTS free radical scavenging activity, ROS (reactive oxygen species) production, NO (Total Nitric oxide), IL-$1{\beta}$, IL-6, TNF-${\alpha}$ production, weight changes in the hind legs of MIA-induced osteoarthritis rat, serum PGE2, TIMP-1, MMP-2, MMP-9, LTB4, hs-CRP, and white blood cells, neutrophils, lymphocytes, monocytes were measured. The volume of cartilage was observed by micro CT arthrography. H&E and Safranin-O staining were used to examine the injury of synovial tissue. Results 1. In the hind leg weight bearing measurement, level of weight was increased. 2. AST, ALT, BUN, creatinine were decreased. 3. The production of total white blood cell was decreased, and the production of neutrophils, lymphocytes, monocytes were significantly decreased. 4. The production of NO, PGE2, TIMP-1, MMP-2, MMP-9, LTB4 were significantly decreased, and the production of hs-CRP was also decreased but with no significance. 5. The cartilage volume was significantly increased. 6. In H&E staining and Safranin-O staning, the cartilage cell appeared to be proliferated, and proteoglycans appeared to be increased. Conclusions Based on the results above, Gamikyejakjimo-tang Herbal Acupuncture has anti-oxidation and anti-inflammation effects, which leads to suppressing the underlying causes and the progression of osteoarthritis.

Osteoarthritis (OA) is the most common form of arthritis associated with ageing. Vitamin D has diverse biological effect on bone and cartilage, and observational studies have suggested it potential benefit in OA progression and inflammation process. However, the effect of vitamin D on OA is still contradictory. Here, we investigated the therapeutic potential of vitamin D in OA. Six-week-old male Wistar rats were injected with monosodium iodoacetate (MIA) to induce OA. Pain severity, cartilage destruction, and inflammation were measured in MIA-induced OA rats. Autophagy activity and mitochondrial function were also measured. Vitamin-D (1,25(OH)₂D3) and celecoxib were used to treat MIA-induced OA rats and OA chondrocytes. Oral supplementation of vitamin D resulted in significant attenuations in OA pain, inflammation, and cartilage destruction. Interestingly, the expressions of MMP-13, IL-1β, and MCP-1 in synovial tissues were remarkably attenuated by vitamin D treatment, suggesting its potential to attenuate synovitis in OA. Vitamin D treatment in OA chondrocytes resulted in autophagy induction in human OA chondrocytes and increased expression of TFEB, but not LC3B, caspase-1 and -3, in inflamed synovium. Vitamin D and celecoxib showed a synergistic effect on antinociceptive and chondroprotective properties in vivo. Vitamin D showed the chondroprotective and antinociceptive property in OA rats. Autophagy induction by vitamin D treatment may be a promising treatment strategy in OA patients especially presenting vitamin D deficiency. Autophagy promoting strategy may attenuate OA progression through protecting cells from damage and inflammatory cell death.

본 실험에서는 primary culture된 연골세포 in vitro 실험모델과 MIA로 유발한 골관절염 in vivo 실험모델을 이용하여 꾸지뽕나무 잎 추출물의 관절염 예방 효과를 확인하였다. 먼저 MTT 시험법을 통해 세포 사용 적정농도를 $500{\mu}g/mL$ 이하로 결정하여 연골세포사멸 억제를 확인하고, 이를 근간으로 골관절염 동물실험 모델에서 골관절염 예방효과를 확인하였다. $H_2O_2$ 처리에 따른 산화적 독성으로 연골세포 사멸을 유도한 실험에서 꾸지뽕 잎 추출물은 정상세포 수준으로 사멸을 억제하였으며, 이러한 효과는 CTL80의 $200{\mu}g/mL$, CTL10의 $300{\mu}g/mL$ 농도에서 비교적 높게 나타났다. 교원질 합성을 억제하고 분해를 촉진시키는 MMPs(MMP-7, MMP-13)의 발현을 실시간 정량 PCR로 측정하여 발현변화를 살펴보았다. 그 결과 앞선 세포실험 결과와 마찬가지로 CTL80과 CTL10 처리군에서 발현이 유의적으로 낮아졌음을 살펴볼 수 있었다. 특히 CTL80에서 MMP-7과 MMP-13의 발현이 농도 유의적으로 감소하였으며, CTL10의 경우 200, $300{\mu}g/mL$ 농도에서 유의적으로 발현이 감소하는 것을 확인하였다. 세포실험 결과를 바탕으로 동물실험에서의 적정농도를 결정하였으며, 동물독성실험 결과 이상이 없음을 확인하고 실험을 진행하였다. 이때 세포실험결과 선정된 두농도(200, $300{\mu}g/mL$) 간의 차이가 미미하여 동물실험에 적용할 경우 비슷한 실험결과가 나타날 것으로 사료되어 두 실험군 간의 결과를 정확히 구분 짓기 위해 200, $500{\mu}g/mL$ 농도를 선정하여 사용하였다. 골관절염 유발 동물모델을 만들기 위해 SD rat의 관절강에 MIA를 injection 하였으며, 꾸지뽕 잎 에탄올 추출물 투여에 따른 관절염 예방 효과를 관찰하기 위해 관절염 유발 2주일 전부터 1일 1회 경구투여를 실시하고, 유발 후 3주간 지속적으로 투여하고 관찰하였다. 동물 관절의 병리학적 변화를 관찰하기 위하여 Micro-CT 촬영 및 분석을 실시한 결과 Control 군은 골의 강도와 밀도가 감소한 반면, 양성대조군인 MTX 투여군에서 정상군과 비슷한 수준으로 회복된 것을 확인하였고, CTL80-200군과 CTL10-500군에서 Control 군에 비해 유의적으로 수치가 감소하여 골관절염에 따른 손상이 감소한 것을 확인하였다. 동물의 관절조직의 H&E 염색을 통한 조직학적인 변화에서는 골관절염 유발로 연골세포의 손상과 뼈조직의 손상을 관찰하였으며 관절형태를 알아볼 수 없을 정도로 손상된 것을 확인하였다. 반면 CTL80과 CTL10에서는 관절강 세포의 형태가 정상군과 비슷한 둥근모양을 띤 양상을 보였으며 연골조직의 형태가 잘 유지되어 Control 군에 비해 꾸지뽕잎의 투여효과가 나타났음을 관찰하였다. 이상의 결과를 통하여 꾸지뽕 잎 에탄올 추출물은 높은 항관절염 효과가 있을 것으로 사료되며, 항관절염 효능을 지니는 기능성 소재로써 개발 가능성을 확인하였다.
