The value of honey dressings in pilonidal cyst healing: a prospective randomized single-center trial. Tech Coloproctol 2023; 27:721-727. [PMID: 36598614 DOI: 10.1007/s10151-022-02740-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Accepted: 12/04/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND Honey is described as a wound healing agent. Many virtues have been attributed to it, in particular, antibacterial properties. The aim of our study was to evaluate its value in healing of wounds after wide excision on pilonidal cyst healing. METHODS A prospective randomized trial was conducted from March 2016 to February 2022 which included patients with a persistent non healed wound which required packing 6 weeks after pilonidal cyst excision. Patients were randomly allocated to simple alginate wick dressings or the same design plus honey. RESULTS Fifty patients were included in each arm. There were 57 men and 43 women. The median age was 22 years (range 19-28 years). The mean healing time was 61 (± 44) days in the wick + honey group compared to 78 (± 55) days in the simple alginate wick group (p = 0.094). There was no significant difference between the two groups in terms of time off work and time without physical activity The VQ-Dermato quality of life score was equivalent in both groups. CONCLUSIONS Tolerability for honey dressings is good and is equivalent to that of alginate dressings in cavity wound care. This trial did not reach a significant difference in its primary endpoint but it shows the value of honey in this indication, although its use requires further study. TRIAL REGISTRATION NUMBER CLINICAL TRIALS: NCT02485860 and EUDRACT: 2015-A00452-47 (10/03/2015).

Abstract
OBJECTIVE Hard-to-heal wounds can be caused by persistent infections or an excess of inflammatory cytokines, proteases and oxidants, and can severely impact the quality of life (QoL) of patients. Due to the paucity of effective treatments and increased resistance to antibiotics, new and improved therapies are required to resolve infections and to simultaneously enhance the healing trajectory. Medical grade honey (MGH) may be a novel and effective treatment approach. METHODS In this case series, we have described six cases of hard-to-heal wounds, and discussed the effects of MGH on infection, wound healing and factors influencing patient QoL (pain, odour and exudate). In all cases, the wounds had persisted for a long period, and previous treatments had been ineffective. Most of the patients had comorbidities, and the majority of the wounds were contaminated with (multiresistant) bacteria, both of which contributed to non-healing. All wounds were treated with L-Mesitran (MGH-based wound care products, Triticum Exploitatie BV, the Netherlands) either as monotherapy or as a complementary therapy. RESULTS Hard-to-heal wounds started healing, infection was controlled and QoL was strongly improved (malodour, exudate levels and pain swiftly decreased) after the application of the MGH. All wounds healed relatively quickly, considering the severity of the wounds and general health of the patients. CONCLUSION In this study, MGH was a useful alternative or complementary therapy to antibiotics and expedited the healing of hard-to-heal wounds.

Beehive Products as Antibacterial Agents: A Review. Antibiotics (Basel) 2021; 10:717. [PMID: 34203716 PMCID: PMC8232087 DOI: 10.3390/antibiotics10060717] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/09/2021] [Accepted: 06/12/2021] [Indexed: 12/31/2022] Open
Abstract
Honeybees are one of the most marvelous and economically beneficial insects. As pollinators, they play a vital role in every aspect of the ecosystem. Beehive products have been used for thousands of years in many cultures for the treatment of various diseases. Their healing properties have been documented in many religious texts like the Noble Quran and the Holy Bible. Honey, bee venom, propolis, pollen and royal jelly all demonstrated a richness in their bioactive compounds which make them effective against a variety of bacterial strains. Furthermore, many studies showed that honey and bee venom work as powerful antibacterial agents against a wide range of bacteria including life-threatening bacteria. Several reports documented the biological activities of honeybee products but none of them emphasized on the antibacterial activity of all beehive products. Therefore, this review aims to highlight the antibacterial activity of honey, bee venom, propolis, pollen and royal jelly, that are produced by honeybees.

Intraincisional medical grade honey decreases the prevalence of incisional infection in horses undergoing colic surgery: A prospective randomised controlled study. Equine Vet J 2020; 53:1112-1118. [PMID: 33340154 DOI: 10.1111/evj.13407] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 10/20/2020] [Accepted: 11/26/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Medical grade honey has previously been described as a prophylactic treatment for wounds. Local prophylactic treatment may be valuable in preventing post-operative incisional infections in horses undergoing colic surgery but has not been evaluated. OBJECTIVES To establish whether medical grade honey gel, applied on the linea alba intraoperatively, decreases the prevalence of incisional infections in horses undergoing colic surgery with no associated adverse effects. STUDY DESIGN Prospective blinded randomised controlled clinical study. METHODS Horses older than 4 months that underwent colic surgery between May 2017 and December 2018 and survived for >2 weeks were included in the study. Horses were allocated 1:1 to treatment or control by block randomisation. In the treatment group, following closure of the linea alba, medical grade honey gel (L-Mesitran Soft® ) was placed in the incision followed by apposition of subcutaneous tissue and skin. Information regarding the incision and post-operative complications was obtained at five time points (24 hours, 48 hours, 5 days, 14 days and 3 months). RESULTS Eighty-nine horses were included in the study. No adverse effects associated with treatment were observed. Horses in the treatment group had a lower rate of incisional infection compared with the control group (8.2% vs. 32.5%, P = .02). The protective effect of MGH had a calculated adjusted odds ratio (OR) of 0.2 (95% CI:0.07-0.8, P = .03). The number of patients required to receive treatment to prevent one case of incisional infection (NNEB) was 4.7. Risk factors associated with infection included: younger age (OR = 27, 95% CI: 2.3 to 306, P = .008) and diarrhoea 48 hours post-operatively (OR = 20, 95% CI: 1.5 to 277, P = .02). MAIN LIMITATIONS Follow-up was performed by different veterinary surgeons, hence not completely uniform. CONCLUSION Local prophylactic treatment with medical grade honey gel in the abdominal incision during surgery is safe and may significantly decrease the prevalence of incisional infections in horses undergoing colic surgery.

Manuka Honey Reduces NETosis on an Electrospun Template Within a Therapeutic Window. Polymers (Basel) 2020; 12:polym12061430. [PMID: 32604824 PMCID: PMC7362002 DOI: 10.3390/polym12061430] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 06/19/2020] [Accepted: 06/23/2020] [Indexed: 12/23/2022] Open
Abstract
Manuka honey, a topical wound treatment used to eradicate bacteria, resolve inflammation, and promote wound healing, is a focus in the tissue engineering community as a tissue template additive. However, its effect on neutrophil extracellular trap formation (NETosis) on a tissue engineering template has yet to be examined. As NETosis has been implicated in chronic inflammation and fibrosis, the reduction in this response within the wound environment is of interest. In this study, Manuka honey was incorporated into electrospun templates with large (1.7–2.2 µm) and small (0.25–0.5 µm) diameter fibers at concentrations of 0.1%, 1%, and 10%. Template pore sizes and honey release profiles were quantified, and the effect on the NETosis response of seeded human neutrophils was examined through fluorescence imaging and myeloperoxidase (MPO) analysis. The incorporation of 0.1% and 1% Manuka honey decreased NETosis on the template surface at both 3 and 6 h, while 10% honey exacerbated the NETosis response. Additionally, 0.1% and 1% Manuka honey reduced the MMP-9 release of the neutrophils at both timepoints. These data indicate a therapeutic window for Manuka honey incorporation into tissue engineering templates for the reduction in NETosis. Future in vivo experimentation should be conducted to translate these results to a physiological wound environment.

Abstract
Over the past few decades, there has been a resurgence in the clinical use of honey as a topical wound treatment. A plethora of in vitro and in vivo evidence supports this resurgence, demonstrating that honey debrides wounds, kills bacteria, penetrates biofilm, lowers wound pH, reduces chronic inflammation, and promotes fibroblast infiltration, among other beneficial qualities. Given these results, it is clear that honey has a potential role in the field of tissue engineering and regeneration. Researchers have incorporated honey into tissue engineering templates, including electrospun meshes, cryogels, and hydrogels, with varying degrees of success. This review details the current state of the field, including challenges which have yet to be overcome, and makes recommendations for the direction of future research in order to develop effective tissue regeneration therapies.

Abstract
BACKGROUND Mupirocin is used specifically for the eradication of nasal meticillin-resistant Staphylococcus aureus (MRSA), but increasing mupirocin resistance restricts its repeated use. The antibacterial effects of manuka honey have been established in vitro; antibacterial activity of other honeys has also been reported. AIM To describe the learning experience from a randomized controlled trial (RCT) comparing the efficacy of medical-grade honey (MGH) with mupirocin 2% for the eradication of nasal MRSA. METHODS Patients colonized in the nose with MRSA and age ≥18 years were recruited. Participants received either one or two courses of MGH or mupirocin 2%, three times per day for five consecutive days. FINDINGS The proportion of patients who were decolonized after one or two courses of treatment was not significantly different between MGH [18/42; 42.8%; 95% confidence interval (CI): 27.7-59.0] and mupirocin 2% (25/44; 56.8%; 95% CI: 41.0-71.7). Non-nasal MRSA colonization was significantly associated with persistent nasal colonization (odds ratio: 5.186; 95% CI: 1.736-5.489; P = 0.003). The rate of new acquisition of mupirocin resistance was 9.75%. CONCLUSION Although not significant, a decolonization rate of 42.8% for MGH was impressive. Our findings suggest that this strategy, which has the potential to combat antimicrobial resistance, should be assessed in similar but larger studies.

Towards Profiles of Resistance Development and Toxicity for the Small Cationic Hexapeptide RWRWRW-NH2. Front Cell Dev Biol 2016; 4:86.

Abstract
RWRWRW-NH2 (MP196) is an amphipathic hexapeptide that targets the bacterial cytoplasmic membrane and inhibits cellular respiration and cell wall synthesis. In previous studies it showed promising activity against Gram-positive bacteria and no significant cytotoxicity or hemolysis. MP196 is therefore used as lead structure for developing more potent antibiotic derivatives. Here we present a more comprehensive study on the parent peptide MP196 with regard to clinically relevant parameters. We found that MP196 acts rapidly bactericidal killing 97% of initial CFU within 10 min at two times MIC. We were unable to detect resistance in standard 24 and 48 h resistance frequency assays. However, MP196 was effective against some but not all MRSA and VISA strains. Serum binding of MP196 was intermediate and we confirmed its low toxicity against mammalian cell lines. MP196 did neither induce NFκB activation nor cause an increase in IL8 levels at 250 μg/mL, and no IgE-dependent activation of basophil granulocytes was detected at 500 μg/mL. Yet, MP196 demonstrated acute toxicity in mice upon injection into the blood stream. Phase contrast microscopy of mouse blood treated with MP196 revealed a shrinking of erythrocytes at 250 μg/mL and severe morphological changes and lysis of erythrocytes at 500 μg/mL. These data suggest that MP196 derivatization directed at further lowering hemolysis could be instrumental in overcoming acute toxicity. The assessment of hemolysis is a critical step in the evaluation of the clinical potential of promising antimicrobial peptides and should be accompanied by microscopy-based morphological analysis of blood cells.

Abstract
Since ancient times, complementary and alternative medicine (CAM; bǔ chōng yǔ tì dài yī xué) have played an important role in human health and welfare. Many therapeutic approaches in healthcare outside the realm of conventional medicine persist in various parts of the world. There is considerable scientific and commercial potential in CAM, which needs to be explored precisely. Cupping therapy ( bá guàn liáo fǎ), one of the CAM, is practiced across the world. This therapy is believed to act by correcting imbalances in the internal bio field, such as by restoring the flow of "Qi (qì)". Cupping involves applying a heated cup to generate a partial vacuum that mobilizes the blood flow and promotes effective healing. This review outlines various tools and techniques of cupping therapy.

Abstract
Infection is a major cause of morbidity and mortality at all stages of chronic kidney disease (CKD). Multiresistant organisms are becoming increasingly common, particularly in the CKD population. Unfortunately, the rapid evolution of antibiotic resistance has not been mirrored by innovation in new antibiotic agents. Novel treatments are therefore urgently needed. Honey has garnered much interest due to its broad-spectrum antibacterial properties based on extensive experimental data. Unlike conventional antibiotics, honey has an added advantage as it appears to avoid inducing antimicrobial resistance in bacteria. This review discusses the potential mechanisms of action and role of honey in infection management in the general population, epidemiology and special challenges of infections in CKD populations, and the clinical trial evidence pertaining to the safety and efficacy of honey for the prevention and treatment of infections in CKD population.

Abstract
BACKGROUND The use of complementary medical treatment in wound management has continued to grow throughout the world. There is a large body of evidence that supports the use of honey as a wound dressing for a wide range of wound types. The authors present an update of present knowledge about honey as a form of complementary medicine in paediatric wound management. METHODS The literature cited was found by searching the PubMed, BIOSIS and ISI Web of Science databases for the phrase 'honey and wound'. Papers where honey was used in a mixture with other therapeutic substances were excluded. Randomised controlled trials as well as case studies were taken into consideration. RESULTS This paper reviews data on the effectiveness of honey in wound healing; 80 citations or references were found that matched the criteria. Furthermore, the wound-healing properties of honey are described and the mechanism of action discussed. The authors' data show that honey induced enhanced epithelialisation, minimised scar formations and had an anti-microbiotic effect. CONCLUSION These results should encourage the use of medical honey in the field of paediatrics. It is a safe and natural substance that induces wound healing at a greater rate than conventional methods.

Abstract
Honey has a complex chemistry, and its broad-spectrum antimicrobial activity varies with floral source, climate, and harvesting conditions. Methylglyoxal was identified as the dominant antibacterial component of manuka honey. Although it has been known that methylglyoxal has antibacterial activity against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus, there is not much information describing its activity against gram-negative bacteria. In this study, we report the effect of methylglyoxal against multidrug-resistant Pseudomonas aeruginosa (MDRP) using 53 clinically isolated strains. We also assessed the effect of deleting the five multidrug efflux systems in P. aeruginosa, as well as the efflux systems in Escherichia coli and Salmonella enterica serovar Typhimurium, on MICs of methylglyoxal. Our results indicate that methylglyoxal inhibits the growth of MDRP at concentrations of 128-512 μg/ml (1.7-7.1 mM) and is not recognized by drug efflux systems.

Abstract
Honey is one of the most ancient remedies for wound care. Current research has shown promising results for its use in wound care. This review is intended to inform readers of the physiological properties of honey and the evidence that exists to support its clinical use. When compared with evidence for current wound treatment, honey has proven to be a safe, effective, and sometimes superior treatment for various wounds. There are currently US Food and Drug Administration-approved medical-grade honey products available in the United States. Although there have been no clinical trials exploring the use of honey in wilderness environments, it may be a safe, improvisational wound treatment. More robust studies are needed for definitive conclusions of its efficacy and safety.

Abstract
In recent years, the treatment of wounds with honey has received an increasing amount of attention from healthcare professionals in Germany and Austria. We conducted a prospective observational multicentre study using Medihoney™ dressings in 10 hospitals - nine in Germany and one in Austria. Wound-associated parameters were monitored systematically at least three times in all patients. Data derived from the treatment of 121 wounds of various aetiologies over a period of 2 years were analysed. Almost half of the patients were younger than 18 years old, and 32% of the study population was oncology patients. Overall, wound size decreased significantly during the study period and many wounds healed after relatively short time periods. Similarly, perceived pain levels decreased significantly, and the wounds showed noticeably less slough/necrosis. In general, our findings show honey to be an effective and feasible treatment option for professional wound care. In addition, our study showed a relationship between pain and slough/necrosis at the time of recruitment and during wound healing. Future comparative trials are still needed to evaluate the extent to which the positive observations made in this and other studies can definitely be attributed to the effects of honey in wound care.

Abstract
Honey has been used to treat wounds throughout the ages. This practice was rooted primarily in tradition and folklore until the late 19th century, when investigators began to characterize its biologic and clinical effects. This overview explores both historic and current insights into honey in its role in wound care. We describe the proposed antimicrobial, immunomodulatory, and physiologic mechanisms of action, and review the clinical evidence of the efficacy of honey in a variety of acute and chronic wound types. We also address additional considerations of safety, quality, and the cost effectiveness of medical-grade honeys. In summary, there is biologic evidence to support the use of honey in modern wound care, and the clinical evidence to date also suggests a benefit. However, further large, well designed, clinical trials are needed to confirm its therapeutic effects.

HUMAN DATA SYNTHESIS Staphylococcus aureus is a common human commensal organism; acquisition of genes encoding an altered penicillin-binding protein confers resistance to beta-lactam antimicrobial drugs. Methicillin-resistant S. aureus (MRSA) are often resistant to non-beta-lactam antimicrobial drugs as well. Originally described as an important cause of nosocomial infection, MRSA colonization and infection are now often identified in humans outside healthcare settings. Like other S. aureus, MRSA may be present without clinical illness. However, when they do cause infection the consequences can be extremely serious. VETERINARY DATA SYNTHESIS The major domestic animal species, including pets and livestock, may become contaminated, colonized, or infected with methicillin-resistant staphylococci, including MRSA. Dogs and cats are more likely to be colonized/infected with Staphylococcus pseudintermedius than S. aureus, but this pathogen can acquire genes encoding methicillin resistance (ie, MRSP). Diagnosis of MRSA or MRSP has implications not only for treatment of infected animals, but for potential zoonotic transmission. CONCLUSIONS MRSA infection is an important cause of morbidity and mortality in humans. Animals may be contaminated, colonized, or infected with MRSA, with implications for the animal's health and as a potential reservoir for human infection. Staphylococci other than S. aureus may also acquire genes for methicillin resistance, and these species can also result in animal and occasionally human morbidity or mortality.

Abstract
Clean, non-contaminated skin surgery is associated with low rates of surgical site infection (SSI), bacterial endocarditis, and joint prosthesis infection. Hence, antibacterial prophylaxis, which may be associated with adverse effects, the emergence of multidrug-resistant pathogens, and anaphylaxis, is generally not recommended in dermatologic surgery. Some body sites and surgical reconstructive procedures are associated with higher infection rates, and guidelines for SSI antibacterial prophylaxis have been proposed for these cases. Large prospective, controlled trials are needed to ascertain the role of oral SSI prophylaxis for these surgical sites and procedures especially in patients with diabetes mellitus who are intrinsically at greater risk of SSI. Topical antibacterial ointment and sterile paraffin appear to make no difference to healing or the incidence of SSIs in clean wounds. Although further research is needed, preliminary studies have shown that intraincisional antibacterials, which may be associated with fewer adverse effects and a lower risk of multidrug-resistant bacteria, could potentially be helpful for SSI prophylaxis. Trials using honey- and silver-impregnated dressings have found no advantage in the healing of chronic wounds. However, several case studies, which need corroboration in larger studies, suggest that these dressings may be helpful in preventing and treating SSIs. Bacterial endocarditis and joint prosthesis infection prophylaxis are not routinely recommended in cutaneous surgery. The updated 2007 American Heart Association guidelines now advocate bacterial endocarditis prophylaxis for high-risk cardiac patients having surgery involving the oral mucosa or infected skin. The latest American Dental Association/American Academy of Orthopaedic Surgery guidelines recommend considering antibacterial prophylaxis for oral procedures where bleeding is anticipated and for surgery involving acute orofacial skin infections if the patient has had a total joint replacement within 2 years or is in a high-risk group and has had a joint replacement at any time.

The intracellular effects of manuka honey on Staphylococcus aureus. Eur J Clin Microbiol Infect Dis 2009; 29:45-50.

Abstract
The purpose of this study was to investigate the effect of manuka honey on Staphylococcus aureus in order to identify the intracellular target site. The mode of inhibition of manuka honey against S. aureus NCTC 10017 was investigated by determining the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and the effect of time on viability. Structural changes were observed by scanning (SEM) and transmission electron microscopy (TEM) of cells suspended for 4 h at 37 degrees C in 0.05 mM Tris buffer containing 10% (w/v) manuka honey and were compared to cells in buffer alone or buffer containing 10% (w/v) artificial honey (to assess osmotic damage). A bactericidal mode of inhibition for manuka honey on S. aureus was established. Marked structural changes in honey-treated cells were seen only with TEM, where a statistically significant increase in the number of whole cells with completed septa compared to untreated cells were observed (P < 0.05). Structural changes found with TEM suggest that honey-treated cells had failed to progress normally through the cell cycle and accumulated with fully formed septa at the point of cell division without separating. Sugars were not implicated in this effect. The staphylococcal target site of manuka honey involves the cell division machinery.

The unusual antibacterial activity of medical-grade Leptospermum honey: antibacterial spectrum, resistance and transcriptome analysis. Eur J Clin Microbiol Infect Dis 2009; 28:1199-208.

Abstract
There is an urgent need for new, effective agents in topical wound care, and selected honeys show potential in this regard. Using a medical-grade honey, eight species of problematic wound pathogens, including those with high levels of innate or acquired antibiotic resistance, were killed by 4.0-14.8% honey, which is a concentration that can be maintained in the wound environment. Resistance to honey could not be induced under conditions that rapidly induced resistance to antibiotics. Escherichia coli macroarrays were used to determine the response of bacterial cells to a sub-lethal dose of honey. The pattern of gene expression differed to that reported for other antimicrobial agents, indicating that honey acts in a unique and multifactorial way; 78 (2%) genes were upregulated and 46 (1%) genes were downregulated more than two-fold upon exposure to the medical-grade honey. Most of the upregulated genes clustered into distinct functional regulatory groups, with many involved in stress responses, and the majority of downregulated genes encoded for products involved in protein synthesis. Taken together, these data indicate that honey is an effective topical antimicrobial agent that could help reduce some of the current pressures that are promoting antibiotic resistance.

Abstract
While the ancient Egyptians and Greeks used honey for wound care, and a broad spectrum of wounds are treated all over the world with natural unprocessed honeys from different sources, Medihoney has been one of the first medically certified honeys licensed as a medical product for professional wound care in Europe and Australia. Our experience with medical honey in wound care refers only to this product. In this review, we put our clinical experience into a broader perspective to comment on the use of medical honey in wound care. More prospective randomized studies on a wider range of types of wounds are needed to confirm the safety and efficacy of medical honey in wound care. Nonetheless, the current evidence confirming the antibacterial properties and additional beneficial effects of medical honey on wound healing should encourage other wound care professionals to use CE-certified honey dressings with standardized antibacterial activity, such as Medihoney products, as an alternative treatment approach in wounds of different natures.

Abstract
The use of honey in wound management has enjoyed a resurgence. This is largely due to the growing clinical problem of antibiotic-resistant bacteria and the combined difficulties for the practitioner in managing chronic wound types, such as burns, leg ulcers or surgical wounds, that may become infected, for example, with methicillin-resistant Staphylococcus aureus or Pseudomonas. The associated costs of treating such wounds are escalating as a result. While the use of honey as a wound dressing has been recognized, at least since Egyptian times circa 2000 BC, it is only more recently, due to the development and licensing of modern honey wound dressings, that such dressings have become more widely available and used in wound management. This article focuses on the use of honey in the treatment of infected wounds and burns. It will examine the effects of honey at the wound bed and its clinical applications, along with the current dressings available. Also discussed are the practical considerations, if, like any wound dressing, honey is to be used safely, appropriately and for the benefit of the patient.

Abstract
OBJETIVO: Avaliar efeitos do uso tópico do mel da abelha silvestre Melipona subnitida na evolução de feridas infectadas de pele. MÉTODO: Ratos Wistar foram distribuídos aleatoriamente em grupos de 6, anestesiados com tiopental sódico 20mg/Kg IP e cetamina 30mg/Kg IM e submetidos a exérese de segmento de 1 cm² de pele total do dorso. Os ratos do grupo C (não infectado) foram tratados com solução salina sobre a ferida diariamente e no grupo MEL (não infectado) as feridas foram tratadas com mel uma vez por dia. Nos grupos C/I e MEL/I as feridas foram inoculadas com solução polimicrobiana. Culturas foram feitas 24 horas após. Caracterizada a infecção, as feridas foram tratadas com solução salina e mel, respectivamente. No terceiro dia de tratamento foi feita nova cultura. Após epitelização foi contado o tempo de cicatrização e as feridas foram biopsiadas para histopatologia e dosagem de TNF-α, IL-1β e IL-6 no tecido. RESULTADOS: O tempo médio de cicatrização do grupo MEL/I foi menor que nos demais grupos (P<0,05). Verificou-se que a densidade de colágeno, leucócitos, fibroblastos e dosagem de citocinas (especialmente TNF) foi maior no grupo infectado e tratado com mel que nos demais grupos. Houve significante redução de bactérias Gram-negativas e positivas nas feridas após o tratamento com mel. CONCLUSÃO: O uso tópico de mel de Melipona subnitida em feridas infectadas da pele de ratos estimulou a resposta imunológica, reduziu a infecção e o tempo de cicatrização.
