This study aims to determine the potential of the Cissus quadrangularis extract to decreased the expression of IL-1 β so that it can to inhibit bone resorption and osteoporosis fracture healing is not delayed union. Forty rats adapted for 1 week, and then divided into four groups with 10 replications. P0 (sham-operated + Osteotomy + CMC Na); P1 (ovariectomy + Osteotomy + CMC Na); P2 (ovariectomy + Osteotomy + Raloxifene 5.4 mg / kg); P3 (ovariectomy + Osteotomy + CQ 750 mg / kg). Osteoporosis induced is made by bilateral ovariectomy in rats, then to make sure that osteoporosis is already happened, 8 weeks post-ovariectomy performed radiology examinations on the femur, then the osteotomy action. IL1-β expression observations performed in at the 2 nd week and 6 th week after osteotomy through the immunohistochemistry examination. The results of immunohistochemistry examination in the 2 nd week showed an increased expression of IL1-β in all groups of rat that did ovariectomy (P1, P2 and P3) were significantly different (p <0.05) with a rat group that didn't ovariectomy, as well P2 dan P3 were significantly different with P1. The Results of immunohistochemistry examination in the 6 th week showed the same pattern with the 2nd week and there is increased IL1-β expression in all groups of rat compared with the results of the examination in the 2nd week. Based on these results it can be concluded that Cissus quadrangularis extract and Raloxifen can decreased the expression of IL-1 β, and the results that don't significantly different, so that these both materials can to inhibit bone resorption and osteoporosis fracture healing don't get delayed union.

AbstrakPenelitian ini bertujuan untuk mengetahui potensi ekstrak Cissus quadrangularis (Cq) dalam menurunkan ekspresi IL-1β sehingga mampu menghambat resorpsi tulang dan kesembuhan fraktur osteoporosis tidak mengalami keterlambatan (delayed union). Empat puluh ekor tikus putih diadaptasikan selama 1 minggu, selanjutnya dibagi menjadi empat kelompok dengan 10 ulangan. P0 (Non ovariektomi + Osteotomi + CMC Na); P1 (Ovariektomi + Osteotomi + CMC Na); P2 (Ovariektomi + Osteotomi + Raloxifene 5,4 mg/kg BB); P3 (Ovariektomi + Osteotomi + Cq 750 mg/kg BB ). Induksi osteoporosis dilakukan dengan cara ovariektomi pada tikus, selanjutnya untuk memastikan bahwa sudah terjadi osteoporosis, 8 minggu pasca ovariektomi dilakukan pemeriksaan radiologi pada tulang femur, kemudian dilakukan tindakan osteotomi. Pengamatan ekspresi IL1-β dilakukan pada minggu ke-2 dan minggu ke-6 pasca osteotomi melalui pemeriksaan imunohistokimia. Hasil pemeriksaan imunohistokimia pada minggu ke-2 menunjukkan adanya peningkatan ekspresi IL1-β pada semua kelompok tikus yang dilakukan ovariektomi ( P1, P2 dan P3) yang berbeda nyata (p<0,05) dengan kelompok tikus yang tidak di ovariektomi, demikian juga P2 dan P3 berbeda nyata dengan P1. Hasil pemeriksaan imunohistokimia pada minggu ke-6 menunjukkan p...
