EFEKTIVITAS EKSTRAK PROPOLIS DALAM PENYEMBUHAN LUKA BAKAR DERAJAT II PADA HEWAN UJI

Luka bakar merupakan salah satu insiden yang sering terjadi dalam kehidupan sehari-hari. Tujuan dari penelitian berdasarkan studi pustaka ini adalah untuk mengetahui efektivitas ekstrak propolis dalam penyembuhan luka bakar derajat II pada hewan uji. Propolis kaya akan manfaat seperti menjadi antimikroba, antibakteri, antimikotik, astringent, spasmolitik, anti-inflamasi, anestesi, antioksidan, antiulcer, antikanker, serta memiliki efek imunomodulator yang dapat mendukung penyembuhan luka bakar derajat II. Senyawa flavonoid, fenol, arginine, asam ferulat, dan albumin berperan baik dalam menurunkan pertumbuhan mikroorganisme, mempercepat perbaikan jaringan dan menghambat munculnya ROS atau Reactive Oxygen Species pada luka bakar.Ekstrak propolis dengan konsentrasi 100% telah terbukti lebih efektif dalam mempercepat penyembuhan luka bakar derajat II pada hewan uji. Pemberian propolis dengan dosis pemberian yang berbeda menunjukkan perbedaan lamanya waktu penyembuhan luka bakar yang ditandai oleh perbedaan nilai rata-rata luas luka bakar dalam setiapwaktu pengukuran. Berdasarkan analisis hipotesis peneliti, efektivitas penyembuhan luka bakar dipengaruhi oleh dosis pemberian ekstrak propolis pada luka bakar tersebut. Dimana keduanya memiliki hubungan yang sebanding, peningkatan dosis pemberian propolis dapat mempercepat penyembuhan luka bakar derajat II.Burns are one of the incidents that often occur in life. The purpose of this research based on literature study was to determine the effectiveness of propolis extract in healing second degree burns in tested animals. Propolis is rich in benefits such as being antimicrobial, antibacterial, antimycotic, astringent, spasmolytic, anti- inflammatory, anesthetic, antioxidant, antiulcer, anticancer, and has an immunomodulatory effect that can support healing of second degree burns. Flavonoids, phenols, arginine, ferulic acid, and albumin have a good role in reducing the growth of microorganisms, accelerating tissue repair and inhibiting the appearance of ROS or Reactive Oxygen Species in burns.Propolis extract with a concentration of 100% has been proven to be more effective in accelerating the healing of second degree burns in test animals. Giving propolis with different doses showed a difference in length of time to heal burns, indicated by differences in the average value of burns in each measurement time. Based on the analysis of the researchers' hypothesis, the effectiveness of healing burns was influenced by the dose of propolis extract on the burns. Both have an equal relation, increasing thedose of giving propolis can accelerate the healing of second degree burns Keywords: second degree burns, propolis, effectiveness of propolisextrac

Molecular Insights into the Antistress Potentials of Brazilian Green Propolis Extract and Its Constituent Artepillin C

Propolis, also known as bee-glue, is a resinous substance produced by honeybees from materials collected from plants they visit. It contains mixtures of wax and bee enzymes and is used by bees as a building material in their hives and by humans for different purposes in traditional healthcare practices. Although the composition of propolis has been shown to depend on its geographic location, climatic zone, and local flora; two largely studied types of propolis: (i) New Zealand and (ii) Brazilian green propolis have been shown to possess Caffeic Acid Phenethyl Ester (CAPE) and Artepillin C (ARC) as the main bioactive constituents, respectively. We have earlier reported that CAPE and ARC possess anticancer activities, mediated by abrogation of mortalin-p53 complex and reactivation of p53 tumor suppressor function. Like CAPE, Artepillin C (ARC) and the supercritical extract of green propolis (GPSE) showed potent anticancer activity. In this study, we recruited low doses of GPSE and ARC (that did not affect either cancer cell proliferation or migration) to investigate their antistress potential using in vitro cell based assays. We report that both GPSE and ARC have the capability to disaggregate metal- and heat-induced aggregated proteins. Metal-induced aggregation of GFP was reduced by fourfold in GPSE- as well as ARC-treated cells. Similarly, whereas heat-induced misfolding of luciferase protein showed 80% loss of activity, the cells treated with either GPSE or ARC showed 60–80% recovery. Furthermore, we demonstrate their pro-hypoxia (marked by the upregulation of HIF-1α) and neuro-differentiation (marked by differentiation morphology and upregulation of expression of GFAP, β-tubulin III, and MAP2). Both GPSE and ARC also offered significant protection against oxidative stress and, hence, may be useful in the treatment of old age-related brain pathologies.
