Lansau adalah ramuan tradisional masyarakat Suku Muna Sulawesi Tenggara yang terdiri dari 44 jenis tanaman yang dipercaya oleh masyarakat setempat berkhasiat untuk mengobati berbagai macam penyakit. Lansau telah digunakan selama ratusan tahun secara turun temurun. Penelitian ini bertujuan untuk mengetahui aktivitas ekstrak etanol ramuan lansau terhadap histopatologi organ ginjal pada model hewan yang mengalami kerusakan fungsi ginjal dengan induksi kombinasi injeksi gentamisin 3,6 mg/kgbb dan suspensi oral piroksikam 100 mg/kgbb. Hewan uji tikus dikelompokkan menjadi 6 kelompok, yaitu normal, kontrol negatif, kontrol positif, ekstrak etanol lansau dosis 6,90; 13,81 dan 27,62 mg/kg bb. Pemberian bahan uji dilakukan secara oral setiap hari selama 4 minggu. Pada minggu kelima hewan dikorbankan, dilakukan pembedahan dan diamati histopatologi organ ginjal meliputi tubulus normal, degenerasi sel tubulus, nekrosis sel tubulus, penyempitan lumen tubulus, adhesi dan atrofi glomerulus. Hasil pengamatan menunjukkan ektrak etanol lansau dosis 6,90; 13,81 dan 27,62 mg/kgbb memiliki kemampuan dalam menghambat kerusakan fungsi ginjal. Berdasarkan histopatologi organ ginjal pemberian ekstrak etanol lansau dosis 13,81 mg/kgbb lebih efektif dalam menghambat kerusakan organ ginjal dengan tidak ditemukannya sel yang mengalami degenerasi dan nekrosis. Kesimpulan dari penelitian ini adalah ektrak etanol lansau mempunyak aktivitas untuk perbaikan fungsi ginjal.

The ethanol extract activity of Lansau, a traditional Muna ethnic concoction, on improving kidney function

Abstract

Lansau is a traditional concoction of the Southeast Sulawesi Muna Tribe community which consists of 44 types of plants that are believed by local people to be efficacious for treating various diseases. Lansau has been used for hundreds of generations. The aim of this study was to determine the activity of ethanol extract of elderly herbs against the histopathology of kidney organs in animal models that have impaired kidney function by induction of a combination of gentamicin injection of 3.6 mg / kgbb and oral suspension of piroxicam 100 mg / kgbb. Rat test animals were grouped into 6 groups, namely normal, negative control, positive control, ethanol extract, or 6.90; 13.81 and 27.62 mg / kg bw. Provision of test material is carried out orally every day for 4 weeks. In the fifth week the animals were sacrificed, performed surgery and observed histopathology of kidney organs including normal tubules, tubular cell degeneration, tubular cell necrosis, tubular lumen constriction, adhesion and glomerular atrophy. The observation results showed an ethanol extract of a dose of 6.90; 13.81 and 27.62 mg / kg have the ability to inhibit damage to kidney function. Based on histopathology of kidney organs, the administration of ethanol extract at a dose of 13.81 mg / kg is more effective in inhibiting kidney organ damage with the absence of degenerated and necrotic cells. The conclusion of this study is the ethanol extract of the elderly has activity to improve kidney function.
