Pengaruh Simvastatin Terhadap Kadar Proliferasi Limfosit Mencit Balb/C yang Diinduce Sepsis dengan LPS

Tujuan : Membuktikan efek simvastatin dosis bertingkat peroral pada mencit yang diberi LPS intraperitoneal terhadap penurunan kadar proliferasi limfosit.
Metode : Penelitian eksperimental laboratorik dengan desain randomized post test only controlled group pada 20 ekor mencit Balb/c yang disuntik lipopolisakarida 10 mg/KgBB intraperitoneal dan simvastatin dosis 0,03 mg, 0,06 mg dan 0,12 mg peroral. Mencit dibagi menjadi 4 kelompok secara random, yaitu K1 sebagai control, K2 yang mendapat simvastatin 0,03 mg, K3 yang mendapat simvastatin 0,06 mg dan K4 yang mendapat simvastatin 0,12 mg. Pemeriksaan limfosit diambil dari kultur limpa setelah 72 jam pemberian simvastatin. Uji statistik yang digunakan adalah parametrik ANOVA dan dilanjutkan Posteriori
Hasil : Kadar rerata limfosit kelompok K1 (1,546 ± 0,106), K2 (0,541 ± 0,046), K3 (0,471 ± 0,013) dan K4 (0,553 ± 0,02). Terdapat penurunan kadar limfosit secara signifikan pada kelompok K2, K3 dan K4 dibanding K1 dengan p <0,05. Tidak terdapat perbedaan bermakna antara kadar limfosit kelompok K2 dengan kelompok K3 dan K4 ( p>0,05) tetapi didapatkan perbedaan bermakna antara kelompok K3 dibandingkan kelompok K4 ( p<0,05).
Simpulan : Simvastatin secara signifikan menurunkan kadar proliferasi limfosit pada mencit yang diberi LPS intraperitoneal. Dosis 0,06 mg memiliki efek menekan kadar proliferasi limfosit paling besar.
