Free radical production and quenching in honeys with wound healing potential. (1/16)
OBJECTIVES: Honey-impregnated wound dressings are now available on drug tariff in the UK, though the modes of action of honeys with antibacterial and wound healing properties are not entirely clear. The action of some but not all of these honeys is linked to the production of hydrogen peroxide on dilution of the honey with wound exudate. The present study investigates both free radical production and the antioxidant potential of some honeys, properties which may have a role to play in wound healing. METHODS: Free radical production and quenching of three honey types (manuka, antibacterial but non-peroxide-producing; pasture, antibacterial peroxide-producing; commercial heat processed, non-antibacterial) was investigated by electron paramagnetic resonance (EPR) spectroscopy; quenching was also examined using a superoxide quenching assay. RESULTS: All honeys tested had antioxidant potential, with manuka able to completely quench added radicals within 5 min of spiking. Only the peroxide-producing honey (pasture PS9) was found to form radicals on dilution. CONCLUSIONS: The ability to modulate production and quenching of free radicals may contribute to the demonstrated ability of some honeys to help in resolving the state of inflammation typifying chronic wounds.

Honey is used as a therapy to aid wound healing. Previous data indicate that honey can stimulate cytokine production from human monocytes. The present study further examines this phenomenon in manuka honey. As inflammatory cytokine production in innate immune cells is classically mediated by pattern recognition receptors in response to microorganisms, bacterial contamination of honey and the effect of blocking TLR2 and -4 on stimulatory activity were assessed. No vegetative bacteria were isolated from honey; however, bacterial spores were cultured from one-third of samples, and low levels of LPS were detected. Blocking TLR4 but not TLR2 inhibited honey-stimulated cytokine production significantly. Cytokine production did not correlate with LPS levels in honey and was not inhibited by polymyxin B. Further, the activity was reduced significantly following heat treatment, indicating that component(s) other than LPS are responsible for the stimulatory activity of manuka honey. To identify the component responsible for inducing cytokine production, honey was separated by molecular weight using microcon centrifugal filtration and fractions assessed for stimulatory activity. The active fraction was analyzed by MALDI-TOF mass spectroscopy, which demonstrated the presence of a number of components of varying molecular weights. Additional fractionation using miniaturized, reverse-phase solid-phase extraction resulted in the isolation of a 5.8-kDa component, which stimulated production of TNF-alpha via TLR4. These findings reveal mechanisms and components involved in honey stimulation of cytokine induction and could potentially lead to the development of novel therapeutics to improve wound healing for patients with acute and chronic wounds.

This study was carried out in order to investigate the potential of using plant oils derived from Leptospermum petersonii Bailey and Syzygium aromaticum L. Merr. Et Perry as natural antifungal agents. The antifungal effects of essential oils at concentrations of 0.05, 0.1, 0.15, and 0.2 mg/ml on the dermatophytes Microsporum canis (KCTC 6591), Trichophyton mentagrophytes (KCTC 6077), Trichophyton rubrum (KCCM 60443), Epidermophyton floccosum (KCCM 11667), and Microsporum gypseum were evaluated using the agar diffusion method. The major constituents of the active fraction against the dermatophytes were identified by gas chromatography-mass spectrometry and high-performance liquid chromatography analysis. The antifungal activities of S. aromaticum oil (clove oil) against the dermatophytes tested were highest at a concentration of 0.2 mg/ml, with an effectiveness of more than 60%. Hyphal growth was completely inhibited in T. mentagrophytes, T. rubrum, and M. gypseum by treatment with clove oil at a concentration of 0.2 mg/ml. Eugenol was the most effective antifungal constituent of clove oil against the dermatophytes T. mentagrophytes and M. canis. Morphological changes in the hyphae of T. mentagrophytes, such as damage to the cell wall and cell membrane and the expansion of the endoplasmic reticulum, after treatment with 0.11 mg/ml eugenol were observed by transmission electron microscopy (TEM). At a concentration of 0.2 mg/ml, L. petersonii oil (LPO) was more than 90% effective against all of the dermatophytes tested, with the exception of T. rubrum. Geranial was determined to be the most active antifungal constituent of L. petersonii oil. Taken together, the results of this study demonstrate that clove and tea tree oils exhibited significant antifungal activities against the dermatophytes tested in this study.

(+info)Using leptospermum honey to manage wounds impaired by radiotherapy: a case series. (5/16)
Radiation-induced tissue injury and wounds with radiation-impaired healing are traumatic for patients and challenging for their caregivers. Standardized management approaches do not exist. The effect of Leptospermum honey as a primary dressing for managing these wounds was assessed in four patients (age range 63 to 93 years) who had previously undergone radiotherapy that left them with fragile friable areas of damaged skin that did not respond to conventional treatment. Compromised areas involved the neck, cheek, groin/perineum, and chest. In patients 1 and 2, after topical application of honey via hydrofiber rope and nonadhesive foam, respectively, improvements in the size and condition of wound/periwound area and a reduction in pain were noted before death or loss to follow-up. After including honey in the treatment regimen of patients 3 and 4, complete healing was noted in 2.5 weeks (with honey and paraffin) and 6 weeks (with honey-soaked hydrofiber rope), respectively. No adverse events were reported. Honey as an adjunct to conventional wound/skin care post radiation therapy shows promise for less painful healing in these chronic wounds. Prospective, randomized, controlled clinical studies are needed to confirm these observations.

(+info)Leptospermum is a genus of flowering plants in the myrtle family, Myrtaceae. It includes around 80 species of shrubs and small trees that are native to Australia and Southeast Asia. The plants are commonly known as tea trees due to their aromatic leaves which have been used to make a medicinal tea.
The essential oil derived from some species of Leptospermum, particularly Leptospermum scoparium (Manuka), has antimicrobial and anti-inflammatory properties. This oil is used in various medical and therapeutic applications, such as in the treatment of wounds, burns, and skin infections.
However, it's important to note that not all Leptospermum species have medicinal properties, and the use of this plant and its derivatives should be done under the guidance of a healthcare professional.
I'm sorry for any confusion, but "Myrtaceae" is not a medical term. It is a taxonomic category in biology, specifically the family name for a group of flowering plants that include eucalyptus, tea tree, and myrtle, among others. These plants have fleshy fruits or dry capsules and contain essential oils with various medicinal properties. If you have any questions related to health or medicine, I'd be happy to try to help answer those!
'Aspergillus ochraceus' is a species of fungi that belongs to the genus Aspergillus. The term 'Aspergillus ochraceus' is used in medical and scientific contexts to refer to this specific type of fungus. It is commonly found in soil, decaying vegetation, and other organic matter, and can also be found in indoor environments such as air conditioning systems, carpeting, and drywall.
While 'Aspergillus ochraceus' is not typically associated with human disease, it can cause invasive aspergillosis in individuals with weakened immune systems, particularly those who have undergone organ transplants or have certain types of cancer. The fungus can also produce toxins that can cause allergic reactions and other health problems in some people.
It's worth noting that while 'Aspergillus ochraceus' is a specific species of fungi, there are many other species of Aspergillus that can also cause human disease, including the more common 'Aspergillus fumigatus'.
Volatile oils, also known as essential oils, are a type of organic compound that are naturally produced in plants. They are called "volatile" because they evaporate quickly at room temperature due to their high vapor pressure. These oils are composed of complex mixtures of various compounds, including terpenes, terpenoids, aldehydes, ketones, esters, and alcohols. They are responsible for the characteristic aroma and flavor of many plants and are often used in perfumes, flavors, and aromatherapy. In a medical context, volatile oils may have therapeutic properties and be used in certain medications or treatments, but it's important to note that they can also cause adverse reactions if not used properly.
