Maltodextrins that contain both simple sugars and polymers of saccharides have been widely used as ingredients in food products and pharmaceutical delivery systems. To date, no much work has been reported on the applications of maltodextrin from broken rice (RB) sources. Therefore, the objective of this work was to investigate thein vitrowound healing efficacy of RB maltodextrin at different conditions. Wounds treated with lower dextrose equivalent (DE) range (DE 10–14) of maltodextrins at a concentration of 10% obtained from RB were found to be able to heal the wounds significantly faster (p<0.01) than maltodextrin with higher DE ranges (DE 15–19 and DE 20–24) and concentrations of 5% and 20%. The findings from both BrdU and MTT assay further confirmed its wound healing properties as the NIH 3T3 fibroblast wounded cells were able to proliferate without causing cytotoxic effect when wounded cell was treated with maltodextrin. All these findings indicated that the RB maltodextrin could perform better than the commercial maltodextrin at the same DE range. This study showed that RB maltodextrins had better functionality properties than other maltodextrin sources and played a beneficial role in wound healing application.

Diabetic wound infections caused by conventional antibiotic-resistant Staphylococcus aureus strains are fast emerging, leading to life-threatening situations (e.g., high costs, morbidity, and mortality) associated with delayed healing and chronic inflammation. Electrospinning is one of the most widely used techniques for the fabrication of nanofibers (NFs), induced by a high voltage applied to a drug-loaded polymer solution. Particular attention is given to electrospun NFs for pharmaceutical applications (e.g., original drug delivery systems) and tissue regeneration (e.g., as tissue scaffolds). However, there is a paucity of reports related to their application in diabetic wound infections. Therefore, we prepared eco-friendly, biodegradable, low-immunogenic, and biocompatible gelatin (GEL)/polyvinyl alcohol (PVA) electrospun NFs (BNFs), in which we loaded the broad-spectrum antibiotic cephradine (Ceph). The resulting drug-loaded NFs (LNFs) were characterized physically using ultraviolet-visible (UV-Vis) spectrophotometry (for drug loading capacity (LC), drug encapsulation efficiency (EE), and drug release kinetics determination), thermogravimetric analysis (TGA) (for thermostability evaluation), scanning electron microscopy (SEM) (for surface morphology analysis), and Fourier-transform infrared spectroscopy (FTIR) (for functional group identification). LNFs were further characterized biologically by in-vitro assessment of their potency against S. aureus clinical strains (N = 16) using the Kirby–Bauer test and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, by ex-vivo assessment to evaluate their cytotoxicity against primary human epidermal keratinocytes using MTT assay, and by in-vivo assessment to estimate their diabetic chronic wound-healing efficiency using NcZ10 diabetic/obese mice (N = 18). Thin and uniform NFs with a smooth surface and standard size (<400 nm) were observed by SEM at the optimized 5:5 (GEL:PVA) volumetric ratio. FTIR analyses confirmed the drug loading into BNFs. Compared to free Ceph, LNFs were significantly more thermostable and exhibited sustained/controlled Ceph release. LNFs also exerted a significantly stronger antibacterial activity both in-vitro and in-vivo. LNFs were significantly safer and more efficient for bacterial clearance-induced faster chronic wound healing. LNF-based therapy could be employed as a valuable dressing material to heal S. aureus-induced chronic wounds in diabetic subjects.

Abstract Bacterial nanocellulose (BNC) is a type of 3-dimensionally structured polymer gel produced by Acetobacter that has recently attracted increased interest in wound healing concerns. To produce an effective antibacterial wound dressing, researchers investigated the manufacturing and structural features of honey-infused BNC reinforced gelatin/aldehyde-modified Guar gum films (H/BNC/Ge/AD-GG). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), mechanical characteristics, water solubility, and degradability were all used to assess the produced films. In addition, the influence of honey addition on the produced films' various properties has been examined. Antibacterial activity, better degradation capability, improved mechanical qualities, and excellent cell adhesion and proliferation by NIH-3T3 fibroblast cells were among the outcomes. The cytotoxicity assay in vitro revealed good cytocompatibility. As a result of the findings, the produced H/BNC/Ge/AD-GG films appear to have a high potential for antibacterial wound dressing applications.

Intravitreal use of vital dyes in combination with the action of endoillumination can induce a cyto- and phototoxic effect on posterior eye segment structures. The search for a staining agent with a maximum safety profile to retinal structures, intensively and selectively coloring vitreous body and vitreoretinal interface structure, remains relevant.Objective: to determine comparative viability of NIH / 3T3 mouse fibroblast cell culture with traditional agents for chromovitrectomy and “Vitreocontrast” suspension with and without endovitreal illumination.Materials and methods. NIH / 3T3 mouse fibroblast cultures contacted with agents for chromovitrectomy (MembraneBlue® Dual, Triamcinolone acetonide, “Vitreocontrast” suspension) and the corresponding controls in a volume of 50 μl / well. The test plate was irradiated with a Photon II illuminator (Synergetics, USA), working distance of 5 mm. The control tablet with the introduced preparations was not exposed to light. Next, the cells were washed and incubated, after which the morphology and lysis of the cells, as well as the number of proliferating relatively negative control of fibroblasts, were evaluated using the vital dye PrestoBlue Cell Viability Reagent. Negative control was the complete growth medium for the cultivation of mouse fibroblasts of the NIH / 3T3 line. The results of the cytotoxic reaction of a culture of mouse fibroblasts of the NIH / 3T3 line were interpreted using the table “The degree of cell response”.Results. Studies have shown that exposure to a source of endovitual illumination does not affect the cytotoxic effect of TA suspension and MembraneBlue® Dual dye. The TA suspension, both after light source and without it, has a moderate cytotoxic effect, and MembraneBlue® Dual has no cytotoxic effect on the culture of mouse fibroblasts of the NIH / 3T3 strain. Without light, “Vitreocontrast” suspension does not have cytotoxic effect on mouse fibroblasts culture NIH / 3T3 line. Light irradiation for 1 h increases the cytotoxicity of “Vitreocontrast” suspension to the level of unsharp cytotoxicity allowed by ISO Standard 10993-5-2011.Conclusion. The safety profile of MembraneBlue® Dual and “Vitreocontrast” suspension allows them to be recommended for use in endovitreal surgery. The cyto- and phototoxicity demonstrated in the experiment with TA suspension can reduce the functional outcomes of retinal surgery.

Purpose: To develop a high performance thin-layer chromatography (HPTLC procedure for quantitation of apigenin in ethanol extract of Matricaria chamomilla (Babunaj) flowers, and to evaluate the extract for in vitro cytotoxic effect on MCF-7 cell lines. Methods: Quantification of apigenin was carried out using a CAMAG TLC system. A combination of toluene, ethyl acetate and formic acid (4.5:3.5:0.2 v/v/v) was used as mobile phase, with densitometry detection at 336 nm. The HPTLC procedure was subjected to validation as per ICH guidelines. The cytotoxicity of the extract was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Results: A sharp apigenin band at Rf of 0.51 was obtained, and the content of apigenin in the extract was 0.062 % w/w. The detection limit (LOD) and quantification limit (LOQ) were 0.19 and 0.57 ng/band, respectively. MTT assay results indicate that M. chamomilla was cytotoxic to Michigan Cancer Foundation-7 (MCF-7) cells, with half-maximal concentration (IC50) of 74 µg/mL. Conclusion: The developed HPTLC method is linear, precise, accurate and specific for the determination of apigenin. M. chamomilla exerts cytotoxic effect on MCF-7 cell line via induction of apoptosis.

Wound healing is a complex multicellular process involving many cell types which include; inflammatory cells, endothelial cells, fibroblasts and keratinocytes. The process involves an orderly sequence of events with four overlapping phases namely; haemostasis, inflammatory, proliferation and remodeling phases.  The process can be facilitated by the use of wound healing agents including herbal remedies from plants. In this study the main objective was to evaluate the in vitro wound healing activity of the resin obtained from Commiphora swynnertonii (C.swynnertonii). First the NIH -3T3 cells viability were evaluated using (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyl Tetrazolium Bromide (MTT) assay. Then the wound scratch assay model was used to evaluate cellular proliferation, closure of the wound and release of matrix metalloproteinase enzymes. Results indicate differences in mean cell viability between different concentrations within 24 hours of incubation. The highest viability was recorded at the concentration of 1% (v/v). The in-vitro wound scratch assay showed positive NIH - 3T3 cells proliferation on the wound area and cells migration when compared with control group (without treatment) at 0 and 24 hours. In addition, C. swynnertonii was able to stimulate secretion of MMP-2 release from NIH - 3T3 cells. MMP-2 is an important enzyme for extracellular matrix remodeling during wound healing suggesting that C. swynnertonii promotes wound healing by stimulating cell proliferation and production of MMP-2 in a mechanism that is currently not known.

The present study was carried out to investigate the wound healing potentials of 17 medicinal plants historically used in Ghana for wound healing. Warm and cold water extracts were prepared from the 17 dried plant species and tested in vitro in the scratch assay with NIH 3T3 fibroblasts from mice. The wound healing scratch assay was used to evaluate the effect of the plants on cell proliferation and/or migration in vitro, as a test for potential wound healing properties. After 21 hours of incubation increased proliferation and/or migration of fibroblasts in the scratch assay was obtained for 5 out of the 17 plant species. HPLC separation of the most active plant extract, which was a warm water extract of Philenoptera cyanescens, revealed the wound healing activity to be attributed to rutin and a triglycoside of quercetin. The present study suggests that Allophylus spicatus, Philenoptera cyanescens, Melanthera scandens, Ocimum gratissimum, and Jasminum dichotomum have wound healing activity in vitro.

Background: Since ancient times, preparations from traditional medicinal plants e.g. Arnica montana, Calendula officinalis or Hypericum perforatum have been used for different wound healing purposes. The aim of this study was to investigate the efficacy of the commercial low dilution homeopathic remedy Similasan® Arnica plus Spray, a preparation of Arnica montana 4x, Calendula officinalis 4x, Hypericum perforatum 4x and Symphytum officinale 6x (0712-2) and medium diluted SIM WuS (Petroleum 15x, Arnica montana 15x, Calcium fluoratum 12x, Calendula officinalis 12x, Hepar sulfuris 12x and Mercurius solubilis 15x; 1101-4), on the wound healing in cultured NIH 3T3 fibroblasts. Both remedies were from Similasan AG (Jonen, Switzerland) and prepared according the German Homoeopathic Pharmacopoeia (GHP) following descriptions 4a for arnica, 3a for marigold and St. John’s wort, 2a for comfrey, 5a for petroleum, and 6 for calcium fluoride, hepar sulfuris and mercurius solubilis. Materials and Methods: Cell proliferation, migration and wound closure promoting effect of the preparations (0712-2, 1101- 4) and their succussed solvents (0712-1, 1101-3) were investigated on mouse NIH 3T3 fibroblasts. Cell viability was determined by WST-1 assay, cell growth using BrdU uptake, cell migration by chemotaxis assay and wound closure by CytoSelect ™Wound Healing Assay Kit which generated a defined wound area. All assays were performed in three independent controlled experiments. In some experiments diluted unsuccussed alcohol (0712-3) was also investigated. Results: Preparations (0712-1), (0712-2), (0712-3), (1101-3) and (1101-4) were investigated at decimal dilution steps from 1x to 4x. Cell viabilty was not affected by any of the substances and (0712-1) and (0712-2) showed no stimulating effect on cell proliferation. Preparation (0712-2) exerted a stimulating effect on fibroblast migration (31.7%) vs 15% with succussed solvent (0712-1) at 1:100 dilutions (p0.05). Positive control 2 ng/ml EGF increased migratory activity of cells by 49.8%. Preparation (0712-2) at a dilution of 1:100 promoted in vitro wound closure by 59.5% and differed significantly (p

Abstract This study aimed to investigate the wound-healing efficacy of Hypericum perforatum and pomegranate seed extract oil combined with curcumin as an anti inflammatory agent. A series of experiments were carried out to determine effective concentrations for H. perforatum oil, pomegranate seed extract oil, and curcumin. Ibuprofen was used as a positive control. The wound-healing effects of the applied compounds were tested according to the migration experiment model performed in HaCaT cells. A real-time cell analyzer (xCELLigence) was used to determine the cytotoxic/proliferative effects of H. perforatum, pomegranate seed oil, ibuprofen, and curcumin in HaCaT cells alone and their combined use at specified concentrations. After examining the noncytotoxic concentrations of H. perforatum oil, pomegranate seed oil, curcumin, and ibuprofen, migration experiments were performed to examine the wound healing properties. According to the results, the wound-healing efficacy of curcumin and H. perforatum combination was better than ibuprofen combinations. Also, according to the results, the wound-healing efficacy of curcumin and pomegranate seed oil combination was better than ibuprofen combinations. It was concluded that both oils had improved wound-healing properties in combination with curcumin or Ibuprofen.
