B ACKGROUND:Alpinia galanga (A. galanga) was reported as a potential medicinal source due to its wide effect. A. galanga rhizome crude extract (ARCE) was reported to have high cytotoxic effect in cancer cells, but low in normal cells. However half maximal inhibitory concentration (IC 50 ) of ARCE is not clearly known yet. Hence, current study was conducted to investigate the IC 50 of ARCE in normal standard fibroblast cell line, NIH-3T3 cells. METHODS:Rhizomes of A. galanga were collected, peeled, dried, milled and weighed. Extraction was performed using maceration method, then filtered and evaporated. ARCE with various concentrations were applied in NIH-3T3 cells for 24 or 48 hours. Cells were documented and counted with 3-(4,5-dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide (MTT) assay. RESULTS:Five hundreds grams of simplicia were macerated with ethanol and evaporated, 1 mg/mL crude extract with total volume of 114 mL was obtained. By addition of ARCE in NIH-3T3 cell culture, number of NIH-3T3 cells were shown less when treated with higher concentration of ARCE. Cell numbers of 0, 3.125, 6.25, 12.5, 25 and 50% ARCE treatment for 24 hours are 11, 531, 11,352, 10,920, 10,365, 9,471, 8,360, respectively, meanwhile for 48 hours are 13,219, 12,686, 12,278, 11,390, 10,279, 8,390, respectively. CONCLUSION: IC 50 of ARCE in 24 hours treatment was 620.5 mg/mL, while in 48 hours treatment was 666.6 mg/ mL. Hence, ARCE is suggested to have low cytotoxic effect in NIH-3T3 cells. KEYWORDS:

Background: In Indonesia, Solanum betaceum cav is a traditional herbal medicine which their skin is often wasted because not many people known its content. Aims: To find out the anti-toxic effect of Solanum betaceum cav peel skin ethanol extract on rat’s renal post-carrageenan induction. Study Design: Laboratory experimental in vivo study. Place and Duration of Study: This research was done at Animal Research Facilities (ARF) Medical Faculty University of Indonesia, at September to December 2021. Methodology: The samples used in this research are male white mice, Wistar strain (Rattus norvegicus) with the body weight 180–220 gram which divided into 5 groups, negative control (saline), positive control (sodium dilcofenac 7mg/kgBW), and Solanum betaceum Cav. peel skin ethanol extract groups (70mg/kgBW, 140mg/kgBW, and 280mg/kgBW).  Mice’s buccal mucosa was injected with Caraagenan 1%. Macroscopic and microscopic observation was done before, 24 hours, 48 hours and 72 hours post caraagenan injection. Results: Phytochemical test showed that Solanum betaceum Cav. peel skin ethanol extract contains phenolic, flavonoid, tannin, and alkaloid. At all doses, anti-toxic effect of Solanum betaceum Cav. peel skin ethanol extract have same healing effectiveness within 48 hours. In positive control, the renal were normal at 48 hours. Meanwhile, the negative control’s healing effectiveness was seen at 72 hours. Conclusion: The anti-toxic effect of Solanum betaceum Cav. peel skin ethanol extract has effective healing process at all doses in 48 hours post-carrageenan induction without affect rats’ body weight, however with lower intensity than positive control which using dilcofenac as anti-inflammatory drug.

Fibroblas berperan dalam proses penyembuhan luka dengan pembentukan pembuluh darah, penggerakan serta proliferasi, deposit matriks ekstraseluler dan remodeling jaringan. Pada penyembuhan luka, netrofil dan makrofag akan mengalami peningkatan penggunaan oksigen sehingga memproduksi ROS, peningkatan produk ini akan menyebabkan stres oksidatif pada fibroblas yang akan mempengaruhi proses migrasi dan proliferasi selama proses penyembuhan luka. Kandungan gugus amino (-NH2) dan gugus hidroksil (-OH) pada nano kitosan mampu mengurangi stres oksidatif fibroblas. Penelitian bertujuan untuk mengetahui kemampuan nano kitosan X. gideon dalam menurunkan produksi ROS fibroblas. Penelitian terbagi menjadi enam kelompok terdiri dari kontrol negatif (H2O2), kontrol pembanding, kontrol asam askorbat, nano kitosan konsentrasi 200, 400, dan 600 µg/mL. Produksi ROS dilihat menggunakan probe 2′,7′-Dichlorodihydrofluorescein diacetate (H2DCF-DA). Produksi fibroblas diperlihatkan dengan intensitas fibroblas terflouresen hijau dihitung menggunakan software image J. Rerata produksi ROS pada kelompok nano kitosan 200, 400, dan 600 µg/mL berbeda signifikan dengan kontrol negatif (p<0,05), sedangkan yang diberikan asam askorbat tidak signifikan (p>0,05) dengan perlakuan 200 dan 600 µg/mL, namun signifikan dengan nano kitosan 400 µg/mL. Nano kitosan X. gideon mampu menurunkan produksi ROS fibroblas pada konsentrasi 400 µg/mL.
