Edge Activator: Effect of Concentration Variation of Tween 80 on Characteristics and Rate of Difusion transfersome sodium diclofenac

Diclofenac sodium is a Transfersom is a transdermal delivery system consisting of phospholipids and edge activators. Transfersom increases the size of the stratum corneum lipid barrier pores, then enters the skin through the drive of the trans-barrier motion and squeezes itself to follow the lipid barrier pore size. The purpose of this study is to determine the effect of the tween-80 concentration as an edge activator on the characteristics and diffusion rate of diclofenac sodium transfersom. Transferom preparation used the vortex-sonication method which was made in five formulae with variations in the concentration ratio of phosphatidylcholine and tween-80 (95:05, 90:10, 85:15, 80:20, and 75:25). The results show that all five formulae have different morphological forms. The results of statistical tests using One-Way ANOVA finds a significant effect (p-value) of the edge activator concentration on the diffusion rate of diclofenac sodium transfersom.

FORMULASI EMULGEL DARI EKSTRAK DAUN KELOR (Moringa oleifera LAM) SERTA EVALUASI AKTIVITAS ANTIOKSIDAN DENGAN METODE DPPH

Moringa (Moringa oleifera Lam) is one of the plants that has high antioxidant activity, especially in the leaves. Emulgel is one of the topical dosage which dermatologically has several beneficial properties, namely thixotropic, not oily, easy to spread, easy to clean, soft, easy to wash, long lasting, transparent and comfortable when used. The purpose of this research was to formulate moringa (Moringa oleifera Lam) leaves extract into emulgel dosage forms and determine the antioxidant activity of the dosage using DPPH method.The research began with extraction of moringa leaves and optimization of the base by varying the concentration of carbopol 940 as gelling consisting of F1 0.5%, F2 1%, F3 1.5% and F4 2%. The base that met the requirements of good physical stability was F2. The F2 base was then made into emulgel dosage with 3 concentration variations of the extract, namely F2a 4%, F2b 5% and F2c 6%. The physical stability test result of each formula met the organoleptic test,the pH test, the dispersion test, the adhesion test, the viscosity test, and the freeze-thaw test. The One way ANOVA statistical test result showed that the p value was greater than 0.05, which meant that the emulgel dosage had good physical stability. The IC50values of each antioxidant activity result were F2a (t0 = 120.464 g/mL; t28 = 144.887 g/mL), F2b (t0 = 113.642 g/mL; t28 = 128.407g/mL), F2c (t0 = 74.745 g/mL; t28 = 90.618 g/mL). The statistical results of the t-test showed thep value = 0,027, (0.05), This indicated that there were significant difference results of the antioxidant activity test between the three formulas on the first day (t0) and on the 28th day (t28).

This study aims to determine the physical characteristics of the bean extract powder that has been stored in a predetermined time variation. The physic properties tested included water content, solubility and organoleptic tests. The results of the sample water content test with storage variations of less than 1, 1, 2 and 3 months respectively were 5.55%, 2.86%, 3.83% and 3.54% and the solubility was 42.67%, 33, 84%, 44.51% and 34.33% for Artificial Gastrid Fluid (AGF) solvents and 31.79%, 35.08%, 43.24 and 34.52% for Water solvents. The results of the organoleptic test showed that the color of the bean extract powder sample with a storage time of ± 2 months was the most preferred by the panelists, Fresh samples had the highest average scores for taste and aroma, of the panelist samples preferred the samples that had been stored for ± 3 months

The Effect of Telmisartan on Collagen Percentages by Picrosirius Staining in the Glomerular Renal Organ of 8% NaCl-Induced Rats

Excessive salt consumption is one of the hypertension and kidney disease factors, while telmisartan is one of antihypertensive drugs used in the therapy. Telmisartan not only blocks angiotensin receptor which leads to the decrease of blood pressure, but also activates peroxisome proliferator activated receptor gamma (PPAR-γ) and inhibits transforming growth expression factor of beta-1 (TGFβ-1). Whether telmisartan decreases the kidney collagen volume fraction of excessive NaCl-induced Wistar rats are studied in this experiment. Twenty five male Wistars 2.5-3 months of age and 100-150 g BW rats were used in this research. They were grouped into 5, each consists of 5 rats. Group I (G I) as first negative control did not receive NaCl and telmisartan. G II as second negative control received NaCl but not telmisartan. G III, IV and V received NaCl and telmisartan 3, 6 and 12 mg/kg BW. The treatments were given every day within 8 weeks. At the day of 56 all rats were sacrificed by mean of neck dislocation and operated to take the kidney. The collagen was stained by picrosirius red staining. Data were expressed as mean ± standard deviation. They were analyzed by parametric test (analysis of variance-ANOVA and paired samples t-test) or nonparametric test (Kruskal-Wallis). A value of p0.05 was considered statistically significant. The results showed that intraglomerular and extraglomerular collagen volume fraction were lower in telmisartan-treated Wistar rats group than negative control group (0.05p0.05). In conclusion, intraglomerular and extraglomerular collagen volume fraction were lower in 8% sodium chloride-induced and telmisartan-treated male Wistar rats than the items of negative control group.

Uji Aktivitas Antibakteri Sediaan Sabun Cair Ekstrak Daun Mengkudu (Morinda citrifolia L.) Terhadap Staphylococcus aureus

The bacteria Staphylococcus aureus are round bacteria that are shaped like a cocci, and are Gram-positive. These bacteria can be found on the skin, genitals, nasal cavity, mouth and around the anus. One of the pharmaceutical products that can maintain skin health and protect the skin is soap. The leaves of noni (M. citrifolia L.) contain various compounds such as flavonoids, tannins, saponins, alkaloids, and triterpenoids which are capable of being antibacterial. This study aims to make a liquid soap formulation from M. citrifolia L. leaf extract and its activity as an antibacterial to S aureus. The leaves of M. citrifolia L. were extracted using 96% ethanol solvent by maceration method until a thick extract was obtained. Soap formulations are made with a concentration of 20% 40% and 60%. Evaluation of soap quality includes organoleptic test, high foam test and pH test. The method of antibacterial testing is carried out in vitro by means of well diffusion. The results on the quality test of the liquid soap formulation showed that the pH and height of the foam had good results and had met the SNI 1996 Standards. From the results showed that formulation III with an extract content of 60% had a large antimicrobial activity with a value of 16.83 mm which was categorized as strong. In positive control (Dettol) 60% antimicrobial activity showed a value of 14.83 mm. The results of statistical tests were carried out by One-Way ANOVA analysis followed by LSD analysis Post hoc, liquid soap extract of M. citrifolia L. had greater antimicrobial potential than the positive control (Dettol).

Formulasi Sediaan Masker Gel Peel-Off dari Ekstrak Buah Tomat (Solanum Lycopersicum L.) Beserta Uji Aktivitas Antioksidan

Tomatoes are well-known as the source of antioxidants due to the content of lycopene, i.e., a potential free radical inhibitor. Gel peel-off masks are among the chemical products containing antioxidants. The first step of the study was extracting tomato fruits by macerating the fruits using alcohol solvents 96%. The obtained thick extract was used as the material of the gel mask; the percentage of the extract comprised 3% (F1), 5% (F2), and 7% (F3), and it used PVA basis 11% and viscolam 3%. According to the result, the gel peel-off masks meet the requirements of physical and storage stability evaluation. The result of the antioxidant test reveals that the IC50 value of the three masks is F1 189.22 µg/mL, F2 89.34 µg/mL, and F3 36.77 µg/mL. Further, the result of T-Test reveals that P-value = 0.019 (α = 0.05), indicating a difference in the result of the antioxidant test of the three formulae in day one (t0) and day 28 (t28).
