    Cataract, a leading cause of blindness, is of special concern in diabetics as it occurs at earlier onset. Polyol accumulation and increased oxidative-nitrosative stress in cataractogenesis are associated with NFκB activation, iNOS expression, ATP depletion, loss of ATPase functions, calpain activation and proteolysis of soluble to insoluble proteins. Tocotrienol was previously shown to reduce lens oxidative stress and inhibit cataractogenesis in galactose-fed rats. In current study, we investigated anticataract effects of topical tocotrienol and possible mechanisms involved in streptozotocin-induced diabetic rats. Diabetes was induced in Sprague Dawley rats by intraperitoneal injection of streptozotocin. Diabetic rats were treated with vehicle (DV) or tocotrienol (DT). A third group consists of normal, non-diabetic rats were treated with vehicle (NV). All treatments were given topically, bilaterally, twice daily for 8 weeks with weekly slit lamp monitoring. Subsequently, rats were euthanized and lenses were subjected to estimation of polyol accumulation, oxidative-nitrosative stress, NFκB activation, iNOS expression, ATP levels, ATPase activities, calpain activity and total protein levels. Cataract progression was delayed from the fifth week onwards in DT with lower mean of cataract stages compared to DV group (p<0.01) despite persistent hyperglycemia. Reduced cataractogenesis in DT group was accompanied with lower aldose reductase activity and sorbitol level compared to DV group (p<0.01). DT group also showed reduced NFκB activation, lower iNOS expression and reduced oxidative-nitrosative stress compared to DV group. Lenticular ATP and ATPase and calpain 2 activities in DT group were restored to normal. Consequently, soluble to insoluble protein ratio in DT group was higher compared to DV (p<0.05). In conclusion, preventive effect of topical tocotrienol on development of cataract in STZ-induced diabetic rats could be attributed to reduced lens aldose reductase activity, polyol levels and oxidative-nitrosative stress. These effects of tocotrienol invlove reduced NFκB activation, lower iNOS expression, restoration of ATP level, ATPase activities, calpain activity and lens protein levels.

    Oxidative and nitrosative stress underlies cataractogenesis, and therefore, various antioxidants have been investigated for anticataract properties. Several vitamin E analogs have also been studied for anticataract effects due to their antioxidant properties; however, the anticataract properties of tocotrienols have not been investigated. In this study, we investigated the effects of topically applied tocotrienol on the onset and progression of cataract and lenticular oxidative and nitrosative stress in galactosemic rats.

    INTRODUCTION: During recent years, there has been growing interest in use of topical vehicle systems to assist in drug permeation through the skin. Drugs of interest are usually those that are problematic when given orally, such as piroxicam, a highly effective anti-inflammatory, anti-pyretic, and analgesic, but with the adverse effect of causing gastrointestinal ulcers. The present study investigated the in vitro and in vivo pharmacodynamic activity of a newly synthesized palm oil esters (POEs)-based nanocream containing piroxicam for topical delivery.

    METHODS: A ratio of 25:37:38 of POEs: external phase: surfactants (Tween 80:Span 20, in a ratio 80:20), respectively was selected as the basic composition for the production of a nanocream with ideal properties. Various nanocreams were prepared using phosphate-buffered saline as the external phase at three different pH values. The abilities of these formulae to deliver piroxicam were assessed in vitro using a Franz diffusion cell fitted with a cellulose acetate membrane and full thickness rat skin. These formulae were also evaluated in vivo by comparing their anti-inflammatory and analgesic activities with those of the currently marketed gel.

    RESULTS: After eight hours, nearly 100% of drug was transferred through the artificial membrane from the prepared formula F3 (phosphate-buffered saline at pH 7.4 as the external phase) and the marketed gel. The steady-state flux through rat skin of all formulae tested was higher than that of the marketed gel. Pharmacodynamically, nanocream formula F3 exhibited the highest anti- inflammatory and analgesic effects as compared with the other formulae.

    CONCLUSION: The nanocream containing the newly synthesized POEs was successful for trans-dermal delivery of piroxicam.

    This study was conducted to evaluate the effects of topical application of aqueous extract of Hericium erinaceus fruiting bodies (HEFB) on the rate of wound healing enclosure and histology of the healed wound. Five groups of male Sprague-Dawley rats were experimentally wounded in the posterior neck area. A uniform wound area of 2.00 cm in diameter, using a circular stamp, was excised from the nape of the dorsal neck of all rats with the aid of a round seal. The animal groups were topically treated, respectively, with 0.2 mL each of sterilized distilled water (sdH2O); Intrasite gel; and 20, 30, and 40 mg/mL HEFB. Macroscopically, those rats whose wounds were dressed with HEFB and those in the Intrasite gel-treated group healed earlier than those treated with sdH2O. Histological analysis of healed wounds dressed with HEFB showed less scar width at wound enclosure and the healed wound contained fewer macrophages and more collagen with angiogenesis, compared to wounds dressed with sdH2O. In conclusion, wounds dressed with HEFB significantly enhanced the acceleration of wound healing enclosure in rats.

    Topical route of administration is the most commonly used method for the treatment of ophthalmic diseases. However, presence of several layers of permeation barriers starting from the tear film till the inner layers of cornea make it difficult to achieve the therapeutic concentrations in the target tissue within the eye. In order to circumvent these barriers and to provide sustained and targeted drug delivery, tremendous advances have been made in developing efficient and safe drug delivery systems. Liposomes due to their unique structure prove to be extremely beneficial drug carriers as they can entrap both the hydrophilic and hydrophobic drugs. The conventional liposomes had several drawbacks particularly their tendency to aggregate, the instability and leakage of entrapped drug and susceptibility to phagocytosis. Due to this reason, for a long time, liposomes as drug delivery systems did not attract much attention of researchers and clinicians. However, over recent years development of new generation liposomes has opened up new approaches for targeted and sustained drug delivery using liposomes and has rejuvenated the interest of researchers in this field. In this review we present a summary of current literature to understand the anatomical and physiological limitation in achieving adequate ocular bioavailability of topically applied drugs and utility of liposomes in overcoming these limitations. The recent developments related to new generation liposomes are discussed.

    Cataract, a leading cause of blindness, is characterized by lenticular opacities resulting from denaturation of lens proteins due to activation of calcium-dependent enzyme, calpain. Magnesium (Mg(2+)) plays an important role not only in maintaining a low lenticular calcium (Ca(2+)) and sodium concentration but also in preserving the lens redox status. Taurine has also been shown to reduce lenticular oxidative stress. Present study evaluated the anticataract effects of magnesium taurate in vivo and in vitro. Among the five groups of 9 Sprague Dawley rats each, two groups received 30% galactose diet with topical (GDMT) or oral treatment (GDMO) with magnesium taurate. Two groups received 30% galactose diet with topical (GDT) or oral vehicle (GDO). Remaining 1 group received normal diet (ND). Weekly slit lamp examination was done during 21 days experimental period and then all rats were sacrificed; Ca/Mg ratio and antioxidant parameters including reduced glutathione (GSH), catalase and superoxide dismutase (SOD) activities were measured in the isolated lenses using ELISA. In the in vitro study, 2 groups of 10 normal rat lenses were incubated in Dulbecco's Modified Eagle's Medium (DMEM) with galactose while 1 similar group was incubated in DMEM without galactose. In one of the groups, galactose containing medium was supplemented with magnesium taurate. After 48 h of incubation, lenses were photographed and Ca(2+)/Mg(2+) ratio and antioxidant parameters were measured as for in vivo study. The in vivo study, at the end of experimental period, demonstrated delay in the development of cataract with a mean opacity index of 0.53 ± 0.04 and 0.51 ± 0.03 in GDMO (p < 0.05 versus GDO) and GDMT (p < 0.01 versus GDT) respectively. Histopathological grading showed a lower mean value in treated groups, however, the differences from corresponding controls were not significant. Lenticular Ca(2+)/Mg(2+) ratio with a mean value of 1.20 ± 0.26 and 1.05 ± 0.26 in GDMO and GDMT was significantly lower than corresponding controls (p < 0.05) and in GDMT no significant difference was observed from ND. Lenticular GSH and catalase activities were significantly lower and SOD activity was significantly higher in all galactose fed groups. However, in GDMT, GSH and catalase were significantly higher than corresponding control with mean values of 0.96 ± 0.30 μmol/gm lens weight and 56.98 ± 9.86 μmol/g lens protein respectively (p < 0.05 for GSH and p < 0.01 for catalase). SOD activity with mean values of 13.05 ± 6.35 and 13.27 ± 7.61 units/mg lens protein in GDMO and GDMT respectively was significantly lower compared to corresponding controls (p < 0.05) signifying lesser upregulation of SOD due to lesser oxidative stress in treated groups. In the in vitro study, lenses incubated in magnesium taurate containing medium showed less opacity and a lower mean Ca(2+)/Mg(2+) ratio of 1.64 ± 0.03, which was not significantly different from lenses incubated in DMEM without galactose. Lens GSH and catalase activities were restored to normal in lenses incubated in magnesium taurate containing medium. Both in vivo and in vitro studies demonstrated that treatment with magnesium taurate delays the onset and progression of cataract in galactose fed rats by restoring the lens Ca(2+)/Mg(2+) ratio and lens redox status.

    This study aims to investigate the use of palm olein as the oil phase for betamethasone 17-valerate (BV) emulsions. The physicochemical properties of the formulations were characterized. In vitro drug release study was performed with the Hanson Vertical Diffusion Cell System; the samples were quantified with HPLC and the results were compared with commercial products. Optimized emulsion formulations were subjected to stability studies for 3 months at temperatures of 4, 25, and 40°C; the betamethasone 17-valerate content was analyzed using HPLC. The formulations produced mean particle size of 2-4 μm, viscosities of 50-250 mPa.s, and zeta potential between -45 and -68 mV. The rheological analyses showed that the emulsions exhibited pseudoplastic and viscoelastic behavior. The in vitro release of BV from palm olein emulsion through cellulose acetate was 4.5 times higher than that of commercial products and more BV molecules deposited in rat skin. Less than 4% of the drug was degraded in the formulations during the 3-month period when they were subjected to the three different temperatures. These findings indicate that palm olein-in-water emulsion can be an alternative vehicle for topical drug delivery system with superior permeability.

    Mupirocin is a promising broad-spectrum antibiotic that is effective in treating MRSA infections. However, due to its rapid elimination and hydrolysis following injection and high protein binding, current therapeutic use is limited to topical administration. Nanotechnology-driven innovations provide hope for patients and practitioners in overcoming the problem of drug degradation by encapsulation. The objective of this research is to develop and characterize Mupirocin-Loaded Nanostructured Lipid Carriers (M-NLC) for intravascular administration. The MNLC was produced by a combination of high shear homogenization and high pressure homogenization of solid (cetyl palmitate) and liquid (caprylic/caprylic acid) biocompatible lipids in 5 different ratios. The mean particle size, polydispersity index (PDI) and the zeta potential (ZP) of the MNLC formulations were between 99.8 and 235 nm, PDI lower than 0.164, ZP from -25.96 to -19.53 and pH ranging from 6.28-6.49. The MNLC formulation also enhances the anti-bacterial activity of mupirocin. All formulation showed sustained drug release and good physical characteristics for three months storage under 25 °C. It also revealed that the MNLC 1 is safe at 250 mg/kg dose in rats. The MNLC 1 also showed a significant increase in plasma concentration in rabbits following IV administration thus, demonstrating an enhancement on its pharmacokinetic profile as compared to free mupirocin.

    To investigate the use of chitosan nanoparticles (CS-TPP-NPs) as carriers for α- and β-arbutin. In this study, CS-TPP-NPs containing α- and β-arbutin were prepared via the ionic cross-linking of CS and TPP and characterized for particle size, zeta potential, and dispersity index. The entrapment efficiency and loading capacity of various β-arbutin concentrations (0.1, 0.2, 0.4, 0.5, and 0.6%) were also investigated. SEM, TEM FTIR, DSC and TGA analyses of the nanoparticles were performed to further characterize the nanoparticles. Finally, stability and release studies were undertaken to ascertain further the suitability of the nanoparticles as a carrier system for α- and β-arbutin. Data obtained clearly indicates the potential for use of CS-TPP-NPs as a carrier for the delivery of α- and β-arbutin. The size obtained for the alpha nanoparticles (α-arbutin CSNPs) ranges from 147 to 274 d.nm, with an increase in size with increasing alpha arbutin concentration. β-arbutin nanoparticles (β-arbutin CSNPs) size range was from 211.1 to 284 dn.m. PdI for all nanoparticles remained between 0.2-0.3 while the zeta potential was between 41.6-52.1 mV. The optimum encapsulation efficiency and loading capacity for 0.4% α-arbutin CSNPs were 71 and 77%, respectively. As for β-arbutin, CSNP optimum encapsulation efficiency and loading capacity for 0.4% concentration were 68 and 74%, respectively. Scanning electron microscopy for α-arbutin CSNPs showed a more spherical shape compared to β-arbutin CSNPs where rod-shaped particles were observed. However, under transmission electron microscopy, the shapes of both α- and β-arbutin CSNP nanoparticles were spherical. The crystal phase identification of the studied samples was carried out using X-ray diffraction (XRD), and the XRD of both α and β-arbutin CSNPs showed to be more crystalline in comparison to their free form. FTIR spectra showed intense characteristic peaks of chitosan appearing at 3438.3 cm-1 (-OH stretching), 2912 cm-1 (-CH stretching), represented 1598.01 cm-1 (-NH2) for both nanoparticles. Stability studies conducted for 90 days revealed that both α- and β-arbutin CSNPs were stable in solution. Finally, release studies of both α- and β-arbutin CSNPs showed a significantly higher percentage release in comparison to α- and β-arbutin in their free form. Chitosan nanoparticles demonstrate considerable promise as a carrier system for α- and β-arbutin, the use of which is anticipated to improve delivery of arbutin through the skin, in order to improve its efficacy as a whitening agent.

    Introduction: Delayed wound healing and a hefty cost of treatment poses a burden to those undergoing treatment for Diabetic wound care. An alternative wound product to speed up wound healing may address this problem. Honey has been recognized around the world for its efficacy as treating wounds, eczema, and inflammation while cinnamon has a variety of biological functions including anti-diabetic, anti-microbial, and anti-inflammatory. As both cinnamon and honey possess different properties in wound healing, it is hypothesized that combining both products can accelerate wound healing. This study is to compare the efficacy of pure honey, pure cinnamon and honey-cinnamon commixture in diabetic wound healing.
    Methods: Three volunteers were selected from Kitamura clinic, Pontianak, Indonesia participated in this study. Each of them was given a different wound product which were pure honey (subject 1), pure cinnamon extract (subject 2), and honey-cinnamon commixture (subject 3). The wound bed percentage, size, and characteristics were recorded and compared. Results: Usage of pure cinnamon was discontinued during the second visit due to its drying effect. Subjects 1 and 3 both presented with an increase in granulation and reduction in sloughing of cells and biofilm. However, subject 3 showed faster wound contraction and reduction in maceration as compared to subject 1.
    Conclusion: Pure cinnamon extract should not be used as a standalone wound product due to its drying properties. However, topical co-administration of honey and Cinnamon cassia extract has a synergistic interaction effect, improves wound healing in diabetic individuals and is recommended as a new topical herbal drug production for treating of the diabetic wound. Further studies on the therapeutic concentration of honey-cinnamon commixture should be conducted.

    Silver preparations are commonly used for burns, but evidence of their effectiveness remains poorly defined. The aim of the study was to evaluate the effectiveness of silver-containing dressings and topical silver for preventing infection and promoting healing in burns wounds through a meta-analysis of the available evidence. The Cochrane Central Register of Controlled Trials and relevant databases were searched. Drug companies and experts in this field were also contacted. Randomised controlled trials (RCTs) of silver dressings or topical silver (used with dressings) compared with non-silver dressings were eligible for inclusion. We identified 14 RCTs involving 877 participants. One small trial of a silver-containing dressing showed significantly better healing time compared to the control [MD -3.6; 95% CI -4.94 to -2.26 for partial thickness burns and MD -3.9; 95% CI -4.54 to -3.26 for superficial burns]. Topical silver showed significantly worse healing time compared to the non-silver group [WMD 3.96; 95% CI 2.41-5.51] and showed no evidence of effectiveness in preventing wounds infection [WMD 2.48; 95% CI 0.39-15.73]. Our review suggests that silver-containing dressings and topical silver were either no better or worse than control dressings in preventing wound infection and promoting healing of burn wounds.

    Pyoderma gangrenosum (PG) is an uncommon, chronic, painful, ulcerative skin disease of unknown origin, often associated with systemic diseases including inflammatory bowel disease, rheumatoid arthritis; monoclonal gammopathy, hepatitis and myeloproliferative disorders. The mainstay of therapy for PG has been high-dose corticosteroids but not all patients have a favourable outcome. Other systemic agents have also been used such as cyclosporine, azathioprine, cyclophosphamide and tacrolimus. However, all these systemic therapies can be complicated by serious side effects. In this paper, we report a series of four patients with pyoderma gangrenosum treated successfully with topical cyclosporine. No side-effects were observed in any of the patients and there was minimal systemic absorption of the topical cyclosporine.

    Quinazoline is an aromatic bicyclic compound exhibiting several pharmaceutical and biological activities. This study was conducted to investigate the potential wound healing properties of Synthetic Quinazoline Compound (SQC) on experimental rats. The toxicity of SQC was determined by MTT cell proliferation assay. The healing effect of SQC was assessed by in vitro wound healing scratch assay on the skin fibroblast cells (BJ-5ta) and in vivo wound healing experiment of low and high dose of SQC on adult Sprague-Dawley rats compared with negative (gum acacia) and positive control (Intrasite-gel). Hematoxylin and Eosin (H&E), Masson's Trichrome (MT) staining and immunohistochemistry analysis were performed to evaluate the histopathological alterations and proteins expression of Bax and Hsp70 on the wound tissue after 10 days. In addition, levels of antioxidant enzymes (catalase, glutathione peroxidase and superoxide dismutase), and malondialdehyde (MDA) were measured in wound tissue homogenates. The SQC significantly enhanced BJ-5ta cell proliferation and accelerated the percentage of wound closure, with less scarring, increased fibroblast and collagen fibers and less inflammatory cells compared with the negative control. The compound also increases endogenous enzymes and decline lipid peroxidation in wound homogenate.

    PURPOSE: To investigate whether topical insulin improves healing rate of corneal epithelial erosions induced during vitreoretinal surgery in diabetics.
    METHODS: We retrospectively reviewed case notes and serial post-operative photographs of 15 eyes of 14 patients who had corneal epithelial debridement performed during various vitreoretinal surgeries to improve one surgeon's view over a 10 month period in 2010.
    RESULTS: Three groups were identified: DTI, comprising diabetics who received topical insulin 1 unit qds postoperatively (n=5); DCT comprising diabetics treated with conventional post-operative medications only (n=5) and NDCT comprising non diabetic patients on conventional post operative therapy (n=5). Only eyes in which the corneal epithelial defect had been serially photographed at time, t= 0, 12, 24, 36, 48, 60, 72 and 120 hours following commencement of topical medications were included. The size of the defect was calculated using local software. DTI eyes had a significantly smaller defect size at t= 24 (p=0.009), 36 (p=0.009), 48 (p=0.015) and 60 hours (p=0.005) compared to DCT eyes and had no statistical difference from NDCT eyes at all times in the Mann Whitney U analysis (p>0.05). In the diabetic operated bilaterally, the insulin treated eye re-epithelialised by 48 hours whereas fellow eye treated conventionally re-epithelialised in 72 hours.
    CONCLUSIONS: Topical insulin or insulin eye drops 1 unit qds may be applied to the corneal surface to normalize the rate of healing of epithelial defects in diabetic patients undergoing epithelial debridement to improve the surgeon's view.

    Topical application of honey to burn and wounds has been found to be effective in controlling infection and producing a clean granulating bed. It is suggested that the wound healing effect of honey may in part be related to the release of inflammatory cytokines from surrounding tissue cells, mainly monocytes and macrophages. It has been reported that honey hastens wound healing by accelerating wound contractions. Microscopic evaluation demonstrated that there was a significant acceleration of dermal repair in wound treated with honey. Macroscopic and microscopic observations under in vivo assessment suggested that the topical application of honey might have favourable influences on the various phases of burn and wound healing hence accelerating the healing process. The regulatory effects of honey are related to components other than the sugars. However, the mechanisms by which honey affects the release of anti inflammatory agents and growth factors from monocytic cells are as yet unclear. Whether honey affects other cell types, particularly endothelial cells and fibroblasts, involved in wound healing also needs to be clarified. The present article is a short review of recent patents on the healing effect of honey in wound and burn management.
