Abstract
Bacterial cellulose (BC) produced by Acetobacter xylinum has great advantages in wound dressing. However, the structural limitation under static culture, and lack of antibacterial properties restrict its application, especially for infectious wound healing. The present study reported an original wound dressing, which was composed of a Janus BC membrane with antibacterial nano-sized copper oxide (CuO) through polydopamine (PDA) conjugation to promote wound healing under infectious condition. The finished product (CuO/PDA/BC membrane) exhibited favorable air permeability, high hydrophilicity and good mechanical properties, as well as strong antibacterial effects by the sustained release of CuO and photothermal effect of CuO/PDA. Furthermore, CuO/PDA/BC membrane inhibited inflammatory response and promoted wound healing in an infectious wound model in vivo. These results suggested that our CuO/PDA/BC membrane had great potential as wound dressing for infectious wound healing.

Exploring Microemulsion Systems for the Incorporation of Glucocorticoids into Bacterial Cellulose: A Novel Approach for Anti-Inflammatory Wound Dressings. Pharmaceutics 2024; 16:504. [PMID: 38675165 PMCID: PMC11054342 DOI: 10.3390/pharmaceutics16040504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 03/05/2024] [Accepted: 03/20/2024] [Indexed: 04/28/2024] Open
Abstract
The effective pharmacological treatment of inflamed wounds such as pyoderma gangraenosum remains challenging, as the systemic application of suitable drugs such as glucocorticoids is compromised by severe side effects and the inherent difficulties of wounds as drug targets. Furthermore, conventional semi-solid formulations are not suitable for direct application to open wounds. Thus, the treatment of inflamed wounds could considerably benefit from the development of active wound dressings for the topical administration of anti-inflammatory drugs. Although bacterial cellulose appears to be an ideal candidate for this purpose due to its known suitability for advanced wound care and as a drug delivery system, the incorporation of poorly water-soluble compounds into the hydrophilic material still poses a problem. The use of microemulsions could solve that open issue. The present study therefore explores their use as a novel approach to incorporate poorly water-soluble glucocorticoids into bacterial cellulose. Five microemulsion formulations were loaded with hydrocortisone or dexamethasone and characterized in detail, demonstrating their regular microstructure, biocompatibility and shelf-life stability. Bacterial cellulose was successfully loaded with the formulations as confirmed by transmission electron microscopy and surprisingly showed homogenous incorporation, even of w/o type microemulsions. High and controllable drug permeation through Strat-M® membranes was observed, and the anti-inflammatory activity for permeated glucocorticoids was confirmed in vitro. This study presents a novel approach for the development of anti-inflammatory wound dressings using bacterial cellulose in combination with microemulsions.

Abstract
Diabetic foot ulcer (DFU) is a common complication of diabetes mellitus which can cause infection, amputation and even death. One of many treatments that can be applied to support the DFU healing processes is by using wound dressings. Bacterial cellulose (BC) is a good material to be used as a wound dressing. However, some of the limitations of BC to be applied as wound dressing are does not possess antibacterial properties and support the healing process. Andaliman (Zanthoxylum acanthopodium) is known to have antioxidant, antibacterial and anti-inflammatory abilities that can support BC as a wound dressing. This research focused on the manufacture of BC/Z. acanthopodium microencapsulated wound dressing composites and evaluate their potential as a DFU wound dressing with a variety of gelatin composition in microencapsulation. The results of FTIR and SEM analysis showed that the Z. acanthopodium impregnation process in BC was successful. The variation of gelatine that used in microencapsulation affected the morphological and effectiveness of the wound dressing. However, overall, the wound dressings showed good antibacterial effect on E. coli and S. aureus bacteria and accelerating the wound closure process 8 times faster (BCAMc12) on the 17th day compared to wounds that did not receive any treatment.

In situ Formation of Polymer Microparticles in Bacterial Nanocellulose Using Alternative and Sustainable Solvents to Incorporate Lipophilic Drugs. Pharmaceutics 2023; 15:pharmaceutics15020559.

Abstract
Bacterial nanocellulose has been widely investigated in drug delivery, but the incorporation of lipophilic drugs and controlling release kinetics still remain a challenge. The inclusion of polymer particles to encapsulate drugs could address both problems but is reported sparely. In the present study, a formulation approach based on in situ precipitation of poly(lactic-co-glycolic acid) within bacterial nanocellulose was developed using and comparing the conventional solvent N-methyl-2-pyrrolidone and the alternative solvents poly(ethylene glycol), CyreneTM and ethyl lactate. Using the best-performing solvents N-methyl-2-pyrrolidone and ethyl lactate, their fast diffusion during phase inversion led to the formation of homogenously distributed polymer microparticles with average diameters between 2.0 and 6.6 µm within the cellulose matrix. Despite polymer inclusion, the water absorption value of the material still remained at ~50% of the original value and the material was able to release 32 g/100 cm2 of the bound water. Mechanical characteristics were not impaired compared to the native material. The process was suitable for encapsulating the highly lipophilic drugs cannabidiol and 3-O-acetyl-11-keto-β-boswellic acid and enabled their sustained release with zero order kinetics over up to 10 days. Conclusively, controlled drug release for highly lipophilic compounds within bacterial nanocellulose could be achieved using sustainable solvents for preparation.

Investigation of the Properties of Linen Fibers and Dressings. Int J Mol Sci 2022; 23:ijms231810480.

Abstract
In antiquity, flax was used as a dressing for healing wounds. Currently, work is underway on the genetic modification of flax fibers to improve their properties. Genetic modifications have resulted in an increased content of antioxidants and more favorable mechanical properties. The works published so far have presented independent tests of fibers and dressings after appropriate technological treatments in cell cultures. This study aimed to compare the properties of the fibers and the dressing produced in cell cultures—hamster fibroblasts—V79. The research material was traditional NIKE fibers; genetically modified M, B, and MB fibers; and linen dressings obtained from these fibers. The extract from 48-h incubation of 40 mg of fiber in the culture medium, which was desolved into 10, 20, and 30 mg, was administered to the cell culture. On the other hand, a linen dressing was placed on cells with an area of 0.5 cm2, 1 cm2, 1.5 cm2, and 2 cm2. Cells with fiber or dressing were incubated for 48 h, and then, biological tests were performed, including cell viability (in propidium iodide staining), cell proliferation (in the SRB assay), evaluation of the intracellular free radical level (in the DCF-DA assay), genotoxicity (in the comet assay), assessment of the apoptotic and necrotic cells (in staining anexin-V and iodide propidium), the course of the cell cycle, and the scratch test. The correlation between apoptosis and genotoxicity and the levels of free radicals and genotoxicity were determined for the tested linen fibers and fabrics. The tests presented that the fibers are characterized by the ability to eliminate damaged cells in the elimination phase. However, the obtained fabrics gain different properties during the technological processing of the fibers into linen dressings. Linen fabrics have better regenerative properties for cells than fibers. The linseed dressing made of MB fiber has the most favorable regenerative properties.
