Pengaruh Pemberian Vitamin E, Isolat Andrografolid Serta Kombinasi Isolat Andrografolid Dan Vitamin E Dalam Pencegahan Terbentuknya Plak Lemak Pada Aorta Tikus

Terbentuknya plak lemak pada dinding pembuluh darah akibat peningkatan kadar lipid dalam darah dapat memicu terjadinya oksidasi pada salah satu lipoprotein yakni LDL. Sehingga diperlukan upaya pencegahan terjadinya oksidasi LDL agar plak lemak pada dinding pembuluh darahtersebut tidak terbentuk.Andrografolid yang merupakan salah satu golongan senyawa diterpen lakton diketahui mempunyai aktivitas dalam penurunan LDL dalam darah. Disisi lain, vitamin E diketahui mempunyai aktivitas antioksidan yang dominan dalam partikel LDL. Tujuan penelitian ini adalah untuk melihat pengaruh pemberian vitamin E, isolat andrografolid serta kombinasi isolat andrografolid dan kombinasi vitamin E dalam pencegahan pembentukan plak lemak pada dinding aorta tikus. Tahapan penelitian ini meliputi penyiapan hewan uji, pemberian induksi pakan lemak serta pengujian pengaruh pemberian kombinasi isolat andrografolid dan vitamin E pada hewan uji selama 2 bulan. Hewan uji dibagi atas 5 kelompok yakni kelompok normal (pakan standar), kelompok negatif (CMC Na 0,1%), kelompok perlakuan 1 (Isolat andrografolid 18 mg/kgBB p.o.), kelompok perlakuan 2 (Vitamin E 10 IU/kgBB p.o.), dan kelompok perlakuan 3 (isolat andrografolid 9 mg/kgBB dan vitamin E 5 IU/kgBB p.o.). Pengambilan aorta hewan uji setelah 2 bulan perlakuan dan dilakukan analisis skoring terhadap histopatologi aorta tersebut. Hasil skoring diolah secara statistik non parametrik dengan taraf kepercayaan 95%. Pemberian kombinasi isolat andrografolid dan vitamin E menunjukkan perbedaan yang bermakna signifikan (p<0,05) dibandingkan dengan kelompok negatif dan kelompok normal sehingga dapat dikatakan pemberian kombinasi isolat andrografolid dan vitamin E mampu mencegah terbentuknya plak lemak namun belum dapat mengembalikan kondisi anatomi aorta seperti kondisi normal
