PurposeTo determine the effect of phacoemulsification on macular volume and thickness using spectral domain optical coherence tomography examinations.MethodsTwenty-seven eyes of 27 subjects who underwent phacoemulsification were studied. All nine areas of the macula were examined by spectral domain optical coherence tomography preoperatively and 2 months postoperatively. Effective phacoemulsification time and absolute phacoemulsification time were also recorded.ResultsThere were statistically significant differences in macular thickness between preoperative and postoperative spectral domain optical coherence tomography examinations in nine areas including macular volume. In the paracentral macular area, the thickness of three quadrants significantly increased (superior P=0.015; temporal P=0.001; and nasal P=0.023). Peripheral macular thickness also increased significantly in the superior (P=0.05) and temporal macular areas (P<0.001). The macular volume increased significantly after phacoemulsification (P<0.001). There were no correlations between absolute/effective phacoemulsification time and macular cellular structures (P>0.05), but a significant correlation (P=0.011) was found between absolute phacoemulsification time and change in macular volume.ConclusionMacular thickness changes in the nasal, superior, and temporal quadrants of the paracentral area and the superior and temporal quadrants of the peripheral area, as well as macular volume, may be used as detailed biomarkers to measure the effects of intraocular pressure fluctuations and maneuvers in phacoemulsification intraocular surgeries.
Abstract. Biocellulose mask sheet is a new found pharmaceutical cosmetic design that widely commercial. Mostly due to it’s biodegradable properties, provide an eco-friendly waste. Combination of Aloe vera essence (AE) and Vit E to provide and determine it’s respective anti-acne properties in biocellulose mask form. Formulation of biocellulose mask with the help of Acetobacter xylinum bacteria varied with different formulae: F1 (Vitamin E 1%), F2 (E 2.5 %), F3 (AE 5%), F4 (AE 2.5%+Vit E 1%) and F5 (AE 5%+Vit E 1%) followed antimicrobials test with common acne bacteria by diffusion disk against Propionibacterium acne (PAC) ATCC 6919 and Pseudomonas aeruginosa (PAA) ATCC 27853. Study revealed that each formulae design F1; F2; F3; F4; F5 tested against PAC diffusion disk resulted 7.86; 11.67; 10.13; 112.10; 10.33 mm respectively. As for PAA diffusion disk resulted 7.76; 11.63; 10.33; 11.67; 11.00 mm respectively. Biocellulose mask containing combination of AE 2.5% and Vit E (F4) would provide the best anti-acne activity amongst other formulae.

Betamethasone valerate and neomycin sulfate are combinations of anti-infection in skin cream. The purpose of this study was to validate intersection absorption spectrum methods and simultaneous determination of betamethasone valerate and neomycin sulfate in the skin cream using 70% ethanol as solvent. The simultaneous determination of a sample was performed with the intersection point spectrophotometric methods when betamethasone valerate and neomycin sulfate absorption spectrum were overlapped and the intersection points were obtained at wavelength 245.4 nm. Each level of betamethasone valerate and neomycin sulfate were calculated using the regression equation. The simultaneous determination of betamethasone valerate and neomycin sulfate in cream supply obtained levels of (107,98 ± 1.6491)% betamethasone valerate and (94.81 ± 2.6958)% neomycin sulfate. The validation test for betamethasone valerate were as follows accuracy was 99.90%, precision was 1.09%, LOD was 0.645 µg/mL, and LOQ was 2.15 µg/mL whereas neomycin sulfate was as follows accuracy was 99.67%, precision was 1.46%, LOD was 2.215 µg/mL, and LOQ was 7.385 µg/mL. The mixture of betamethasone valerate and neomycin sulfate used a wavelength of 245.4 nm as the point of intersection of the absorption spectrum and the results met Indonesian pharmacopeia requirements and this method satisfied the validation requirements.
Objective: The study aimed to investigate the characteristic pectin from banana peels (Musa balbisiana ABB) and formulation as a polymeric carrier in gastrorententive floating beads.Methods: Pectin from banana peel was isolated using a citric acid solvent with varying concentration (2.5%, 5%, and 7.5%) at 80°C for 90 min. Characterization of pectin included determination of yield, equivalent weight methoxyl content (Me), galacturonic acid (GaA), and degree esterification. Floating beads of amoxicillin prepared by the ionotropic gelation method used calcium ion as cross-linking and sodium bicarbonate as gas-forming agent. Three formulations of amoxicillin were formulated using different percentage of pectin. The prepared beads were evaluated for particle size, drug entrapment efficiency, morphological study, floating lag time, floating time, swelling properties, in vitro drug release, and study of drug release kinetics.Results: The result showed citric acid concentration 7.5% was optimum condition for isolated pectin from banana peels with the percent of yield was 9.51%; 6.29% Me; 62.82% GaA; and degree of esterification 48.46%. Floating time of beads was ≥12 h and drug entrapment efficiency F3 was highest (51%). In vitro drug release confirmed F3 was the best formulation as it releases 92% at 5 h with followed Higuchi model kinetics drug release. Floating beads amoxicillin showed differences of drug release compared with conventional dosage form of amoxicillin (p<0.05).Conclusion: This study confirmed these beads can entrap amoxicillin and also can successfully deliver the drug targeted stomach for a prolong duration drug release.

BACKGROUND: The content of secondary metabolites in mobe leaves has the potential to be used in wound healing. Artocarpine, one of the secondary metabolites found in mobe leaves, is reported to affect the expression of transforming growth factor-beta (TGF-β) protein, thereby increasing fibroblast cell proliferation and accelerating the wound healing process. AIM: This study aims to determine the wound healing activity of nanoemulgel-containing ethanol extract of mobe leaves. MATERIALS AND METHODS: The method used in this study was experimental using chemicals ethanol 96%, Carbopol 940, PEG 400, Propylene glycol, Methyl Paraben, Propyl Paraben, Triethanolamine, Aqua Destillata. Mode leaves which were taken purposively were then formulated in nanoemulgel preparations which were tested for wound healing in male rats. The nanoemulgel preparation was then evaluated which included homogeneity, emulsion type, pH, viscosity, dispersion, and measurement of the nanoemulgel globules of mobe leaf extract, stability of the nanoemulgel preparation. Tests for the healing effect of burns were carried out on male rats for 14 days. RESULTS: Mobe leaves ethanol extract can be formulated into nanoemulgel dosage forms. This study showed wound healing activity of nanoemulgels with concentration variation of mobe leaves ethanol extract. The percentage of wound diameter reducing and fibroblast cells value were showed to increase and significantly different to negative control (p < 0.05) in 14 days. Platelet-derived growth factor (PDGF)-BB and TGF-β1 immunoexpression evaluation result showed significantly different to Blanko group (p < 0.05) in 14-day observation. CONCLUSION: From this study, nanoemulgel mobe can stimulate more fibroblast cell proliferation by greatly expressing TGF-β1 and PDGF BB in burn wounds.
