Healing of leprosy-associated chronic plantar wounds with a novel biomembrane containing latex proteins from Calotropis procera. BRAZ J BIOL 2024; 84:e281674. [PMID: 39292137 DOI: 10.1590/1519-6984.281674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 07/15/2024] [Indexed: 09/19/2024] Open
Abstract
Pre-clinical assays demonstrated that a 1% polyvinyl alcohol biomembrane containing latex proteins (10%) from the medicinal plant Calotropis procera was biocompatible and stimulated healing of incisional and excisional wounds in murine models, and the mechanistic aspects were established. The efficacy of the biomembrane (BioMemCpLP) to promote healing of chronic ulcers in leprosy patients was investigated. The study started with 28 volunteers. Five were excluded later due to different disconformities. Ulcers from 15 patients were continuously treated with BioMemCpLP for 56 days. Five patients were treated only with silver sulfadiazine and three patients received plain hydrocolloid wound dressings with high absorption capacity. In all cases, wound dressings were renewed three times a week for 56 days and ulcers were evaluated weekly for contraction and healing progress. The extent of the healed area in the ulcers treated with BioMemCpLP was greater than in the control groups. Approximately 88% of ulcers treated with BioMemCpLP were fully healed before day 56, against 6% in both control groups. This result was not correlated with age/gender, duration or location of ulcers, deformity or whether or not the patient was cured of leprosy. The results showed that BioMemCpLP was beneficial for treatment of ulcers suffered by leprosy patients without noticeable side effects.

Abstract
This work investigated the healing properties of proteins extracted of latex (HdLP) on excisional wounds. Cell toxicity of HdLP was investigated carried out in murine fibroblasts after incubation with HdLP (12.5-100 μg/ml). The dermal irritability test was performed to evaluate dermal reactions. The wounds were performed and treated with vehicle or HdLP (0.5 %, 1.0 %, and 2.0 %). The macroscopic parameters, histological analysis and measurement of inflammatory markers and mediators were evaluated. HdLP did not exhibit cytotoxicity and did not induce skin irritation. HdLP stimulated the release of IL-1β at the beginning of the inflammatory phase. This effect probably favored the earlier release of IL-10 by macrophages, during the proliferative phase. The shortening and completeness of healing were characterized by fibroblast proliferation and the presence of newly synthesized collagen fibers. This was accompanied by well-organized re-epithelialization. The involvement of latex proteins in this activity is reported for the first time.

Abstract
The chronification of ulcers or sores may result in a dramatic outcome such as amputation. Currently, the search for plant based treatments of various diseases/disorders, including complicated ones, is getting the attention of researchers worldwide. The soluble latex protein fraction (CpLP) obtained from Calotropis procera (Apocynaceae) was previously demonstrated to accelerate wound healing by topical application or when incorporated in a polyvinyl alcohol biomembrane (BioMemCpLP). Here, in vitro assays were performed to investigate and characterize the biocompatibility and bioactivity of latex proteins dressing. Macrophages (RAW 264.7), fibroblasts (L929) and keratinocytes (HaCaT) cell lines were used to evaluate the effect of CpLP. These cell lines were exposed to concentrations of CpLP comparable to those found in BioMemCpLP during 24-72 h. The cytotoxicity, proliferation, release of wound healing mediators (TGF-β, VEGF, IL-10, IL-6, IL-1β, TNF-α and NO) and migration of cells (E-cadherin and β-catenin) incubated with CpLP was assessed and the cell adhesion to BioMemCpLP as well. The results showed that CpLP has no cytotoxic effects. It induced a suitable balance between pro- and anti-inflammatory mediators, enhanced proliferation and re-epithelialization in all cell lines, but the intensity of each effect was different at various doses in all cell strains. The BioMemCpLP stimulated cell adhesion to PVA substrate. The CpLP-PVA based biomembrane can be a good option for healing of different wounds.

Abstract
Introduction: We previously described the manufacture and characterization of hydrogel forming, thin film, anti-infective wound dressings made from Poly Vinyl Alcohol (PVA) and silver nanoparticles, crosslinked by heat. However, these films were designed to be inexpensive for simple manufacture locally in Africa. In this new study, we have further developed PVA dressings by manufacturing films or electrospun membranes, made from blends of PVA with different degrees of hydrolyzation, that contain silver salts and degrade in a controlled manner to release silver in a sustained manner over 12 days. Methods: Films were solvent cast as films or electrospun into nanofibre membranes using blends of 99 and 88% hydrolyzed PVA, containing 1% w/w silver sulphadiazine, carbonate, sulphate, or acetate salts. Dissolution was measured as weight loss in water and silver release was measured using inductively coupled plasma (ICP) analysis. Results: Cast films generally stayed intact at PVA 99: PVA 88% ratios greater than 40:60 whereas electrospun membranes needed ratios greater than 10:90. Films (40:60 blend ratio) and membranes (10:90) all released silver salts in a sustained fashion but incompletely and to different extents. Electrospun membranes gave more linear release patterns in the 2–12 day period and all salts released well. Conclusion: Blended PVA cast films offer improved control over hydrogel dissolution and silver release without the need for high temperature crosslinking. Blended PVA electrospun membranes further improve membrane dissolution control and silver release profiles. These blended PVA films and membranes offer improved inexpensive systems for the manufacture of long lasting anti-infective hydrogel wound dressings.

Abstract
Background:
Hydrogel has a three-dimensional network structure that is able to absorb
a large amount of water/liquid and maintain its original structure. Hemicellulose (HC) is the second
most abundant polysaccharide after cellulose in plants and a heterogeneous polysaccharide
consisting of various saccharide units. The unique physical and chemical properties of hemicellulose
make it a promising material for hydrogels.
Methods:
This review first summarizes the three research hotspots on the hemicellulose-based
hydrogels: intelligence, biodegradability and biocompatibility. It also overviews the progress in
the fabrication and applications of hemicellulose hydrogels in the drug delivery system and tissue
engineering (articular cartilage, cell immobilization, and wound dressing).
Results:
Hemicellulose-based hydrogels have many unique properties, such as stimuliresponsibility,
biodegradability and biocompatibility. Interpenetrating networking can endow appropriate
mechanical properties to hydrogels. These properties make the hemicellulose-based hydrogels
promising materials in biomedical applications such as drug delivery systems and tissue
engineering (articular cartilage, cell immobilization, and wound dressing).
Conclusion:
Hydrogels have been widely used in biomedicine and tissue engineering areas, such
as tissue fillers, drug release agents, enzyme encapsulation, protein electrophoresis, contact lenses,
artificial plasma, artificial skin, and tissue engineering scaffold materials. This article reviews the
recent progress in the fabrication and applications of hemicellulose-based hydrogels in the biomedical
field.

Abstract
Cysteine peptidases (EC 3.4.22) are the most abundant enzymes in latex fluids. However, their physiological functions are still poorly understood, mainly related to defense against phytopathogens. The present study reports the cDNA cloning and sequencing of five undescribed cysteine peptidases from Calotropis procera (Aiton) Dryand (Apocynaceae) as well as some in silico analyses. Of these, three cysteine peptidases (CpCP1, CpCP2, and CpCP3) were purified. Their enzymatic kinetics were determined and they were assayed for their efficacy in inhibiting the hyphal growth of phytopathogenic fungi. The mechanism of action was investigated by fluorescence and atomic force microscopy as well as by induction of reactive oxygen species (ROS). The deduced amino acid sequences showed similar biochemical characteristics and high sequence homology with several other papain-like cysteine peptidases. Three-dimensional models showed two typical cysteine peptidase domains (L and R domains), forming a "V-shaped" active site containing the catalytic triad (Cys, His, and Asn). Proteolysis of CpCP1 was higher at pH 7.0, whereas for CpCP2 and CpCP3 it was higher at 7.5. All peptidases exhibited optimum activity at 35 °C and followed Michaelis-Menten kinetics. However, the major difference among them was that CpCP1 exhibited highest Vmax, Km, Kcat and catalytic efficiency. All peptidases were deleterious to the two fungi tested, with IC50 of around 50 μg/mL. The peptidases promoted membrane permeabilization, morphological changes with leakage of cellular content, and induction of ROS in F. oxysporum spores. These results corroborate the hypothesis that latex cysteine peptidases play a role in defense against fungi.

Bacterial cellulose membrane associated with red propolis as phytomodulator: Improved healing effects in experimental models of diabetes mellitus. Biomed Pharmacother 2019; 112:108640. [PMID: 30784929 DOI: 10.1016/j.biopha.2019.108640] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Revised: 01/25/2019] [Accepted: 01/28/2019] [Indexed: 12/21/2022] Open
Abstract
Since early times, propolis has been used in folk medicine. The red propolis, collected in the northeast region of Brazil has been highlighted due to its popular use as an antimicrobial, with anti-inflammatory and healing properties, which are associated with its chemical composition. Here, we combine a bacterial membrane with red propolis to treat wounds of diabetic mice. This work aims to evaluate a biocurative from bacterial cellulose associated with red propolis in diabetic mice as wound healing model. Biocuratives from bacterial cellulose membrane and different extracts of red propolis were produced. The qualification and quantification of the presence of propolis chemical compounds in the membrane were investigated through high-resolution mass spectrometry (HRMS). Tests in vivo with biocuratives were performed on Swiss male diabetic mice induced by estroptozotocin. The animals were submitted to a surgical procedure and a single lesion was produced in the dorsal region, which was treated with the biocuratives. Macroscopic assessments were performed at 2, 7 and 14 postoperative days, and biopsies were collected on days 0, 7 and 14 for histological analysis, myeloperoxidase enzyme activity (MPO) and cytokines (TNF-α, IL-1β, and TGF-β). Altogether, ten compounds were identified in membranes and five were further quantified. The ethyl acetate extract showed more red propolis markers, and the most prevalent compound was Formononetin with 4423.00-2907.00 μg.g-1. Macroscopic analyses demonstrated that the two groups treated with red propolis (GMEBT and GMEAE) showed significantly greater healing capabilities compared to the control groups (GS and GMS). An increase in leukocyte recruitment was observed, confirmed by the activity of the enzyme myeloperoxidase (MPO) in GMEBT and GMEAE groups. The levels of TNF-α were significantly higher in wounds stimulated with red propolis, as well as in TGF-β (GMEBT and GMEAE) on day 7. This was different from the IL-1β levels that were higher in the control groups (GS and GMS). In summary, the biocuratives produced in this work were able to accelerate the wound healing process in a diabetic mouse model. In this way, the traditional knowledge of red propolis activity helped to create a biotechnological product, which can be used for diabetic wound healing purpose.
