Abstract
Kerusakan hati akibat penggunaan obat, terutama parasetamol
dalam dosis tinggi, dapat menyebabkan gangguan fungsi hati yang
ditandai dengan peningkatan kadar enzim AST dan ALT. Penelitian ini
bertujuan untuk mengevaluasi efektivitas ekstrak etanol daun kepel
dalam menurunkan kadar AST dan ALT serta memperbaiki gambaran
histopatologi hati tikus putih jantan galur Wistar yang diinduksi
parasetamol.
Penelitian ini menggunakan 25 ekor tikus putih jantan galur
Wistar yang dibagi menjadi lima kelompok, yaitu kontrol positif, kontrol
negatif, serta tiga kelompok perlakuan ekstrak etanol daun kepel dosis
100, 200, dan 300 mg/KgBB. Ekstrak diberikan selama 7 hari, kemudian
tikus diinduksi parasetamol pada hari ke-8, dan pada hari ke-9 dilakukan
pemeriksaan kadar AST-ALT serta pengamatan histopatologi hati. Data
dianalisis menggunakan uji one way ANOVA dan dilanjutkan dengan uji
Tukey Post Hoc.
Hasil penelitian menunjukkan bahwa pemberian ekstrak etanol
daun kepel mampu menahan peningkatan kadar enzim AST dan ALT
pada tikus jantan yang diinduksi parasetamol dibandingkan kontrol
negatif. Gambaran histopatologi hati pada kelompok perlakuan
menunjukkan tingkat kerusakan yang lebih ringan, ditandai dengan
minimalnya degenerasi sel hati dan infiltrasi sel radang serta tidak
ditemukannya nekrosis. Dosis 300 mg/KgBB memberikan efek
hepatoprotektor yang paling optimal. Dengan demikian, ekstrak etanol
daun kepel memiliki aktivitas hepatoprotektor dalam mencegah
kerusakan hati akibat induksi parasetamol.
Liver injury caused by drug use, particularly high-dose
paracetamol, can lead to impaired liver function, which is commonly
indicated by increased levels of AST and ALT enzymes. This study
aimed to evaluate the effectiveness of ethanolic extract of kepel
(Stelechocarpus burahol) leaves in reducing AST and ALT levels and
improving liver histopathological features in paracetamol-induced male
Wistar rats.
This study used 25 male Wistar rats divided into five groups:
positive control, negative control, and three treatment groups receiving
ethanol extract of kepel leaves at doses of 100, 200, and 300 mg/kg body
weight. The extract was administered for 7 days, followed by
paracetamol induction on day 8. On day 9, AST and ALT levels were
measured and liver histopathological observations were performed. Data
were analyzed using one-way ANOVA followed by Tukey’s post hoc
test.
The results showed that administration of the ethanol extract of
kepel leaves was able to prevent the increase in AST and ALT levels in
paracetamol-induced rats compared to the negative control.
Histopathological examination revealed milder liver damage in the
treated groups, characterized by minimal hepatocellular degeneration
and inflammatory cell infiltration, with no evidence of necrosis. The dose
of 300 mg/kg body weight exhibited the most optimal hepatoprotective
effect. Therefore, the ethanol extract of kepel leaves has hepatoprotective
activity in preventing paracetamol-induced liver damage.
