ABSTRAKCampuran Daun sirsak dan Kulit buah manggis sekarang ini banyak digunakan sebagai fitoterapi penyakit kanker dan antioksidan. Tetapi penggunaan bahan ini belum diketahui data keamanannya. Tujuan dilakukan penelitian adalah untuk mengetahui efek sitotoksik campuran ekstrak daun sirsak dan kulit buah manggis terhadap sel vero dan sel AML12. Uji sitotoksik dapat memprediksi keberadaan senyawa yang bersifat toksik secara in vitro menggunakan sel normal atau sel yang telah mengalami transformasi. Uji ini menggunakan 2 jenis cell line, yaitu sel vero dan sel AML12. Sampel berupa simplisia daun sirsak dan kulit buah manggis yang dibuat ekstrak dengan menggunakan etanol 96%. Konsentrasi uji yang digunakan adalah 100; 50; 25; 12,5; 6,25 dan 3,125 g/mL untuk sel vero dan 500; 250; 125; 62,5; 31,25 dan 15,625 g/mL untuk sel AML12. Kultur sel dilakukan di wellplate 96 diinkubasi didalam inkubator CO2 pada suhu 37C selama 24 jam kemudian ditambahkan sampel uji dan selanjutnya diinkubasi kembali didalam inkubator CO2 pada suhu 37C selama 24 jam. Langkah selanjutnya uji MTT dan kemudian dibaca dengan ELISA reader pada panjang gelombang 570nm. Diperoleh hasil sebagai berikut: IC50 55,97 g/mL pada sel vero, dan 43,292 g/mL pada sel AML12. Kesimpulannya sampel campuran ekstrak daun sirsak dan kulit buah manggis ini mempunyai efek toksik terhadap sel vero dan sel AML12 (IC50100 g/mL).Kata kunci: Sitotoksik, Daun sirsak, Kulit buah manggis, sel vero, sel AML12, IC50 ABSTRACTMix of soursop leaves and mangosteen pericarp use as cancer phytotherapy and antioxidant, but it is not yet known its toxicities data. The aim of this study was evaluate cytotoxicity effect of mix of soursop leaves and mangosteen pericarps extract on vero cells and AML12 cells. Toxicity study is one ways to predict the presence of toxic compounds using normal cells or cells that have undergone a transformation. That study was using vero cell and AML12. Samples was ethanolic extract of soursop leaves and mangosteen pericarp. The test dose were 100; 50; 25; 12,5; 6,25 dan 3,125 g/mL in vero cell and 500; 250; 125; 62,5; 31,25 dan 15,625 g/mL in AML12. Cells were cultured in well plate 96 and incubated in CO2, temperature 37C for 24 hours and then added samples and incubated incubated in CO2, temperature 37C for 24 hours. Cell was added MTT and read with ELISA reader. The results showed IC50 55,97g/mL in vero cells and 43,292 g/mL in AML12. Conclusion of

Reconstructed Human Epidermis (RHE) is an artificial epidermis made in such a way that it resembles human skin, and can be used for the identification of irritant chemicals, especially for cosmetic and topical medicinal products. Currently the new RHE is produced by European and American countries, whose skin physiology is very different from Indonesia. Based on this, the Center for Research on Drugs and Food, NADFC of Republic of Indonesia took the initiative to develop the reconstruction of keratinocyte, melanocytes and fibroblasts cells into RHE adapted to the anatomical and physiological functions of the skin of Indonesians. RHE is made from an epidermal layer composed of keratinocyte and melanocytes cells that are reconstructed with a dermis layer composed of fibroblast and collagen cells. Keratinocyte, melanocytes and fibroblasts cells are cultured on suitable mediums by adding a suitable growth medium. To find out that RHE has been successfully reconstructed, measured percentage of cell life, made histology preparation to see the existence of cell nucleus, and conducted Immunohistochemical examination to see existence of integration (bond) between antigen. From the research results can be seen that keratinocyte cells grown on culture medium Keratinocyte SFM (IX) with rEGF supplements; melanocyte cells grown on Melanocyte 254 culture medium with HMGS supplementation; and fibroblast cells grown on Fibroblast M 106 culture medium with LSGS supplementation. The percentage of epidermal cell life grew well in the planting of 10 Â 10 4 cells /mL keratinocytes and 0.25 Â 10 4 cells /mL of melanocyte cells and survived until the 11 th day with live cell percentage of 93.45%. In making preparation for histology with HE staining, there is a cell life in RHE tissue. Used Immunohistochemical (IHC) examination using cytokeratin 10 antibody marker to view physiological function of epidermal tissue.

Objective: The main purpose of this study is to characterize Hibiscus rosa-sinensis L. mucilage (MHR) powder as superdisintegrant and to decide the optimum concentration of Hibiscus rosa-sinensis L. Methods: Characterization was conducted in many tests such as organoleptic, swelling ratio, solubility, polysaccharide, viscosity, particle size distribution, flowability and compressibility index. Next, MHR powder was included in fast disintegrating tablet (FDT) domperidone formulation in several concentrations and compared with FDT domperidone formulation that using sodium starch glycolate as superdisintegrant. Results: The result of characterization of MHR powder were brownish powder, specific smell like traditional medicines, swelling ratio of 24, solubility of 0.426±0.034 mg/ml, positive polysaccharide, the viscosity of 491.33±119.44 cps (2% w/v), 4520.00±1224.42 cps (4% w/v), Dv(10) of 26.2 µm, Dv(50) of 157 µm, Dv(90) of 260 µm, Dv(100) of 380 µm, flowless, and average compressibility index of 26.75±1.79%. The optimum MHR powder concentration was 1% because the average disintegration time was 39.67±4.73 seconds and the average wetting time was 66.33±14.29 seconds. Those times were faster than domperidone FDT that used this superdisintegrant in other concentrations or sodium starch glycolate in the same concentration. Conclusion: Hibiscus rosa-sinensis L. mucilage powder can be used as superdisintegrant in FDT formulation with an optimum concentration of 1%.
