Rutin and quercetin are flavonoid compounds containing in the extract of mulberry (Morus alba L.) leaves have an influence on the cardiovascular system. This study aims to assessment of the blood pressure effect and cardiac puls after giving ethanolic extract of mulberry leaves. The extract was made using 95% ethanol by remaseration method. The content of rutin and quercetin in the extract were determined by using HPLC(High Performance Liquid Chromatography). The formula of the encapsulation containing extract 0.25% w/v, chitosan 0.5mg/mL and TPP (sodium tripolyphosphate) 1mg/mL. Characterization of extract encapsulated was done on the particle size, encapsulation efficiency and FTIR. Extract encapsulated was given to rats orally, subsequently arterial blood pressure and heart rate were measured using Coda Non-Invasive Blood Pressure System. The results showed that mulberry extract contains rutin (0.879±0.138) mg/g and quercetin (4.427±0.065) mg/g. Ratio of chitosan-TPP with 0.5:1 forms particle size were 25.11-45.2 nm, encapsulation efficiency (76.14±2.29)%. Mulberry leaves extract and encapsulated extract could decrease arterial blood pressure.

Piper betle leaf in extract form is more effective than crude drug. Eugenol is a component in the extract that has antibacterial activity but irritate. Patch of piper betle leaf extract was used on the mucosa to make oral cavity hygiene. Antibacterial activity was influenced by the release of eugenol from the patch. Release enhancer substances (RES) such as glycerin, propylen glicol and tween 80 were added in patch formulation to increase the release of active substances. The aim of the research was to investigate the physicochemical properties, eugenol release profiles, and local tolerance test of the patch. Extract of piper betle leaf was made using infundation method. Patch was made according to the variation concentration of extract (1, 2 and 4%) and RES (glycerine, propylen glycol and tween 80) using chitosan as vehicle. Patch produced solvent casting method. Patch obtained was tested for swelling index, folding endurance, surface pH, antibacterial activity, release of eugenol, and local tolerance. Data obtained were analyzed descriptively. The result showed that the addition of RES did not affect the surface pH but increase the water absorption with in inconsistent way except patch with tween 80. The flexibility (folding endurance value) increased, and the highest amount of eugenol released was achieved by patch using propylen glicol. Patch with tween 80 and glycerin for all extract concentration and patch with 1% extract concentration using propylen glycol showed medium sensation (local tolerance), and patch with 2 and 4% extract using propylen glycol showed severe sensation.

Background: The expression of 8-oxo-dG is defined as one form of damaged DNA occuring as the result of oxidation reaction due to X ray exposure. Panoramic radiography exposure has been widely known to be able to increase micronucleus which are signing the early stage and as biomarker in carsinogenesis mechanism. Purpose: The purpose of this research was to determine the correlation between micronucleus number and 8-oxo-dG expression as a result of panoramic radiography exposure. Methods: Twelve New Zealand male rabbits aging 6 months were divided into 4 groups. Group I were rabbits that represented 0 day, group II represented 3th day, group III represented 6th day, and group IV represented 9th day after the panoramic radiography exposure. Respectively samples were swabbed at mandibular anterior gingival mucosa before and after the panoramic radiography exposure. The swabbed samples were coloured by using Feulgen-Rossenbeck modified staining for calculating the amount of micronucleus formation. Expression of 8-oxodG was detected using immunohistochemical of rabbit’s gingival mucosa epithelium. Statistical analysis were carried out on pearson correlation. Results: There was a highest increasing of micronucleus on the 9th day after panoramic radiography exposure. Meanwhile, there was significant correlation (p=0,049) of the increasing amount of micronucleus and 8-oxo-dG expression in negatively correlation (r = -0,578). The increasing of micronucleus formation on the 9th day after panoramic radiography exposure was accordance with some previous studies. The expression score of 8-oxo-dG decreases as the day goes by. Conclusion: There was a correlation between the number of micronucleus and expression score of 8-oxo-dG.Latar belakang: Ekspresi 8-oxo-dG adalah suatu bentuk kerusakan DNA yang terjadi akibat reaksi oksidatif dari paparan sinar X. Paparan radiografi panoramik telah diketahui menyebabkan peningkatan jumlah mikronukleus yang merupakan biomarker tahap dini mekanisme karsinogenesis. Tujuan: Tujuan penelitian ini adalah untuk meneliti korelasi antara jumlah mikronukleus dan ekspresi 8-oxo-dG akibat paparan radiografi panoramik. Metode: Sebanyak 12 ekor kelinci New Zealand jantan usia 6 bulan dibagi menjadi 4 kelompok. Kelompok I merupakan kelinci untuk mewakili hari ke-0, kelompok II untuk mewakili hari ke-3, kelompok III untuk mewakili hari ke-6, dan kelompok IV untuk mewakili hari ke-9 setelah paparan radiografi panoramik. Terhadap seluruh kelinci dilakukan usapan pada mukosa gingiva anterior rahang bawah sebelum dan sesudah dilakukan paparan radiografi. Selanjutnya terhadap sampel usapan itu dilakukan pewarnaan menggunakan teknik pewarnaan modifikasi Feulgen-Rossenbeck untuk menghitung jumlah mikronukleus. Ekspresi 8-oxo-dG dinilai dari pemeriksaan imunohistokimia pada sel epitel mukosa gingiva kelinci. Analisis statistik menggunakan uji korelasi Pearson. Hasil: Peningkatan jumlah mikronukleus paling tinggi terjadi pada hari ke-9 setelah paparan radiografi panoramik. Sementara itu, terdapat korelasi yang signifikan (p=0,049) antara peningkatan jumlah mikronukleus dan ekspresi 8-oxo-dG dengan arah korelasi yang negatif (r=-0,578). Peningkatan jumlah mikronukleus yang terjadi pada hari ke-9 setelah paparan radiografi panoramik ini sesuai dengan penelitian sebelumnya. Dengan bertambahnya hari skor ekspresi 8-oxo-dG semakin menurun. Simpulan: Terdapat korelasi antara jumlah mikronukleus dan skor ekspresi 8-oxo-dG.
