Kunci regulator terhadap respons inflamasi diketahui melalui aktivasi interleukin-1β (IL-1β). Makrofag merupakan sel fagosit mononuklear berperan dalam sistem imun innate dan adaptif. Sitokin yang disekresikan makrofag sebagai respons terhadap patogen antara lain IL-1, IL-6, IL-12, TNF-α, dan chemokine. Minyak atsiri temu putih (Curcuma zedoaria Rosc.) diduga memiliki efek anti inflamasi. Tujuan penelitian ini adalah untuk mengetahui kadar IL-1β pada makrofag terekspose aggregat bakteri actinomycetemcomitans setelah pemberian minyak atsiri temu putih. Subjek penelitian adalah 10 ekor tikus Wistar jantan yang dibagi menjadi 2 kelompok (perlakuan dan kontrol), masing-masing kelompok terdiri atas 5 ekor. Kelompok perlakuan diberi minum minyak atsiri temu putih dosis 30,6 μl/ml dan kelompok kontrol diberi aquabides selama 14 hari. Gingiva anterior rahang bawah tikus diolesi A.actinomycetemcomitans sebanyak 100 μl dalam CMC 2% pada hari ke-7 setelah pemberian minum bahan uji dan kontrol selama 7 hari. Pada hari ke-15, tikus pada masing-masing kelompok dianestesi lalu makrofag dikoleksi dari cairan peritoneal. Kadar IL-1β makrofag diukur menggunakan ELISA kit (R&D Systems, USA), selanjutnya data dianalisis menggunakan uji-t. Hasil penelitian menunjukkan terdapat penurunan kadar IL-1β setelah perlakuan. Perbandingan kelompok perlakuan dan kontrol menunjukkan perbedaan bermakna (p < 0,05). Disimpulkan bahwa minyak atsiri temu putih kemungkinan memiliki efek anti inflamasi melalui penurunan kadar IL-1β makrofag.IL-1β level of macrophage exposed to A. actinomycetemomitans decreases after administration Curcuma Zedoaria volatile oil. Activation of interleukin-1β (IL-1β) is a key regulator of the inflammatory response. Macrophage is a phagocytic mononuclear cell that plays an important role in innate and adaptive immune response. The cytokine secreted by macrophages in response to pathogen are IL-1, IL-6, IL-12, TNF-α and chemokine. Curcuma zedoaria volatile oil may have anti inflammation effect. The aim of this study was to investigate IL-1β level of macrophage exposed to A. actinomycetemcomitans after administration Curcuma zedoaria volatile oil. The subjects were 10 male Wistar rats, which divided into two groups (treatment and control), each group 5 rats. In the treatment group, 30,6 μl/ml Curcuma zedoaria volatile oil was administered per oral for 14 days and the control group used aquabidest. In the 7th days, 100 μl A. actinomycetemcomitans in CMC 2% were applied on the anterior gingival mandible for 7 days. Rats were anesthetized in the 15th days then macrophage was collected from peritoneal. Interleukin-1β level of macrophage was measured using ELISA kit (R&D Systems, USA). Data were analyzed using t-test. The result showed IL-1β level decreased after treatment. The comparison between treatment and control was significant difference (p<0.05). It can be concluded that Curcuma zedoaria volatile oil may have anti inflammation effect through reducing the IL-1β level of macrophage.
