Pengaruh Pemberian Ekstrak Lengkuas (Alpinia Galanga) Terhadap Gambaran Histologik Payudara Mencit (Mus Musculus) Yang Diinduksi Benzo(a)pyrene

: Galangal (Alpinia galanga) is one of the plants that is often used for cancer therapy. Galangal contains different active ingredients, one of which is 1 'acetoxy chavicol acetate (ACA) which serves as an anticancer through its action as an anti-inflammatory agent, induction of apoptosis and inhibition of proliferation. Benzo(a)pyrenes (BAP) are five-ringed Polycyclic Aromatic Hydrocarbons (PAHs), a group of mutagenic and carcinogenic organic compounds. This study aimed to determine the effect of galangal extract on histological features of mice's breast induced by benzo(a)pyrene. This was an experimental laboratory study using mice as experimental animals. Subjects were 15 mice, divided into negative control group (5 mice) and two treatment groups (5 mice each). All mice were fed with standard pellet throughout the experiment. Mice in group A (negative control) received no treatment; mice in group B were administered with benzo(a)pyrene for 14 days then were given no treatment for the next 14 days; and mice in group C were induced by benzo(a)pyrene and were given galangal extract for 14 days then were given no treatment for the next 14 days. The result of this study revealed changes in mice breast histological features in the form of hyperplasia of cuboid epithelial cells of lactiferous ducts in group B and C, however the manifestation in group C was less pronounced than that was seen in group B. Conclusion: Oral administration of galangal extract subcutaneously was able to inhibit the cuboidal ductal lactiferious epithelial cell hyperplasia of mice breast induced by benzo(a)pyrene
