Honey May Boost Healing of Pediatric Peritoneal Dialysis Exit Sites

Topical Honey in the Management of Pediatric Peritoneal Dialysis Exit Sites

Perit Dial Int. 2016 11-12;36(6):684-687

International guidelines in peritoneal dialysis (PD) advocate for regular application of topical mupirocin in chronic PD exit-site care. A strong evidence base links this treatment to reduced rates of exit-site infections and peritonitis. However, emerging reports of increasing mupirocin resistance and gram-negative infections are threatening the long-term viability of topical antibiotic ointments as a prophylactic treatment.

Medical grade honey has multiple proven antibacterial and wound healing properties. High-quality randomized controlled trial evidence (the HONEYPOT trial), however, does not support the use of topical medical-grade honey over antibiotic ointments for the prevention of exit-site infection and peritonitis in adults. Pediatric representation in these studies is low, and these findings may not extrapolate to the pediatric context, which has a higher incidence of PD-related infection and a lower prevalence of diabetes.We present a series of 8 pediatric patients treated with topical Medihoney (Comvita, Paengaroa, New Zealand) in the context of poor exit-site condition, persistent infection, and recurrent granuloma where the addition of honey was felt to produce remarkable improvement in exit-site status.

Medihoney is the first-line prophylactic exit-site ointment in PD exit sites at our institution and has been implicated in the salvage of peritoneal access in some patients. No exclusively pediatric studies have been performed; however, existing literature suggests a beneficial effect in promoting healing of infected wounds with a lower risk of developing antimicrobial resistance.

Iranian Brown Propolis May Help Treat Stroke

Brown propolis attenuates cerebral ischemia-induced oxidative damage via affecting antioxidant enzyme system in mice

Biomed Pharmacother. 2016 Nov 23. pii: S0753-3322(16)31436-6

Oxidative stress plays a critical role in ischemic brain injury. Superoxide dismutase (SOD) and glutathione peroxidase (GPx) are the enzymes underlying the endogenous antioxidant mechanisms affected by stroke and are considered as oxidative stress biomarkers. Brown propolis (BP) is a bioactive natural product with a set of biological activities that in turn may differ depending on the area from which the substance is originated.

The aim of this study was to investigate the effect of water-extracted brown propolis (WEBPs), from two regions of Iran, against cerebral ischemia-induced oxidative injury in a mouse model of stroke. Experimentally, the chemical characterization and total polyphenol content were determined using GC/MS and Folin-Ciocalteu assay respectively. Seventy-two adult male mice were randomly divided into the surgical sham group, control group (treated with vehicle), and four groups of WEBPs-treated animals.

The WEBPs were administered at the doses of 100 and 200mg/kg IP, during four different time points. Oxidative stress biomarkers (SOD and GPx activity, SOD/GPx ratio), lipid peroxidation (LPO) index (malondialdehyde content) and infarct volume were measured 48h post stroke. Behavioral tests were evaluated 24 and 48h after stroke. WEBPs treatment resulted in significant restoration of antioxidant enzymes activity and a subsequent decrease in LPO as well as the infarct volume compared to the control group. Sensory-motor impairment and neurological deficits were improved significantly as well.

These results indicate that Iranian BP confers neuroprotection on the stroke-induced neuronal damage via an antioxidant mechanism which seems to be mediated by the endogenous antioxidant system.

Anti-Cancer Potential in Australian Propolis

A sedge plant as the source of Kangaroo Island propolis rich in prenylated p-coumarate ester and stilbenes

Phytochemistry. 2016 Nov 24. pii: S0031-9422(16)30255-2

Propolis samples from Kangaroo Island, South Australia, were investigated for chemical constituents using high-field nuclear magnetic resonance spectral profiling.

A type of propolis was found containing a high proportion of prenylated hydroxystilbenes. Subsequently, the botanical origin of this type of propolis was identified using a beehive propolis depletion method and analysis of flora. Ligurian honey bees, Apis mellifera ligustica Spinola, were found to produce propolis from resin exuded by the Australian native sedge plant Lepidosperma sp. Montebello (Cyperaceae).

The plants, commonly known as sword sedge, were found to have resin that matched with the propolis samples identified as the most abundant propolis type on the island containing C- and O-prenylated tetrahydroxystilbenes (pTHOS) in addition to a small amount of prenylated p-coumarate. The isolation of five pTHOS not previously characterized are reported: (E)-4-(3-methyl-2-buten-1-yl)-3,4',5-trihydroxy-3'-methoxystilbene, (E)-2,4-bis(3-methyl-2-buten-1-yl)-3,3',4',5-tetrahydroxystilbene, (E)-2-(3-methyl-2-buten-1-yl)-3-(3-methyl-2-butenyloxy)-3',4',5-trihydroxystilbene, (E)-2,6-bis(3-methyl-2-buten-1-yl)-3,3',5,5'-tetrahydroxystilbene and (E)-2,6-bis(3-methyl-2-buten-1-yl)-3,4',5-trihydroxy-3'-methoxystilbene.

A National Cancer Institute 60 human cell line anticancer screen of three of these compounds showed growth inhibitory activity. The large Australasian genus Lepidosperma is identified as a valuable resource for the isolation of substances with medicinal potential.

Propolis Boosts Therapeutic Effect of Antibiotic


Studies on the therapeutic effect of propolis along with standard antibacterial drug in Salmonella enterica serovar Typhimurium infected BALB/c mice

BMC Complementary and Alternative Medicine
Published: 25 November 2016Background

Antibiotic resistance is an emerging public health problem. Centers for Disease Control and Prevention (CDC) has described antibiotic resistance as one of the world’s most pressing health problems in 21st century. WHO rated antibiotic resistance as “one of the three greatest threats to human health”. One important strategy employed to overcome this resistance is the use of combination of drugs. Many plants, natural extracts have been shown to exhibit synergistic response with standard drugs against microorganisms. The present study focused on the antibacterial potential of propolis in combination with the standard antibiotic Cefixime against the typhoid causing bacteria i.e. Salmonella.

Methods

Ethanolic extract of propolis was taken for the present work. For the experiment BALB/c mice were taken as animal model and divided into ten groups. Along with normal and infected control groups, four different combinations of cefixime and propolis were used. Biochemical, hematological and histopathological indices were studied by following the standard protocols.

Results

In BALB/c mice, Salmonella causes severe biochemical, hematological and histopathological alterations by 5th day of infection. Ethanolic extract of propolis at a dose of 300 mg/kg body weight of mice when used alone to treat Salmonella infection in mice gave significant results by 30th day of treatment. Similarly, when cefixime (4 mg/kg body weight of mice) was used to treat infection in mice, significant results as compared to infected control were observed after 5th day. But when propolis and cefixime were used together in different concentrations in combination therapy, evident results were observed after 5 days of treatment. The levels of various liver and kidney function enzymes, blood indices and the histopathology of liver, spleen and kidney were restored to near normal after 5 days of treatment and at much lower doses as compared to the effective dose when used alone.

Conclusion

The study confirmed that significant results were observed in three combinations of cefixime and propolis as compared to infected controls. Propolis acted synergistically with cefixime and enhanced the efficacy of antibiotic and reduced its effective dose in combined therapy.

Bee Venom Possible Broad Spectrum Antiviral Agent

Inhibitory effects of bee venom and its components against viruses in vitro and in vivo

J Microbiol. 2016 Dec;54(12):853-866. Epub 2016 Nov 26.

Bee venom (BV) from honey bee (Apis Melifera L.) contains at least 18 pharmacologically active components including melittin (MLT), phospholipase A2 (PLA2), and apamin etc. BV is safe for human treatments dose dependently and proven to possess different healing properties including antibacterial and antiparasitidal properties. Nevertheless, antiviral properties of BV have not well investigated.

Hence, we identified the potential antiviral properties of BV and its component against a broad panel of viruses. Co-incubation of non-cytotoxic amounts of BV and MLT, the main component of BV, significantly inhibited the replication of enveloped viruses such as Influenza A virus (PR8), Vesicular Stomatitis Virus (VSV), Respiratory Syncytial Virus (RSV), and Herpes Simplex Virus (HSV). Additionally, BV and MLT also inhibited the replication of non-enveloped viruses such as Enterovirus-71 (EV-71) and Coxsackie Virus (H3). Such antiviral properties were mainly explained by virucidal mechanism. Moreover, MLT protected mice which were challenged with lethal doses of pathogenic influenza A H1N1 viruses.

Therefore, these results provides the evidence that BV and MLT could be a potential source as a promising antiviral agent, especially to develop as a broad spectrum antiviral agent.

Sustained-Release Bee Venom Particles

Preparation and characterization of bee venom-loaded PLGA particles for sustained release

Pharm Dev Technol. 2016 Nov 24:1-20

Bee venom-loaded poly(lactic-co-glycolic acid) (PLGA) particles were prepared by double emulsion-solvent evaporation, and characterized for a sustained-release system. Factors such as the type of organic solvent, the amount of bee venom and PLGA, the type of PLGA, the type of polyvinyl alcohol, and the emulsification method were considered. Physicochemical properties, including the encapsulation efficiency, drug loading, particle size, zeta-potential, and surface morphology were examined by Fourier transform infrared (FT-IR) spectroscopy, differential scanning calorimetry (DSC), and X-ray diffraction (XRD). The size of the bee venom-loaded PLGA particles was 500 nm (measured using sonication). Zeta-potentials of the bee venom-loaded PLGA particles were negative owing to the PLGA. FT-IR results demonstrated that the bee venom was completely encapsulated in the PLGA particles, indicated by the disappearance of the amine and amide peaks. In addition, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis indicated that the bee venom in the bee venom-loaded PLGA particles was intact. In vitro release of the bee venom from the bee venom-loaded PLGA particles showed a sustained-release profile over 1 month. Bee venom-loaded PLGA particles can help improve patients' quality of life by reducing the number of injections required.

Sicilian Black Honeybee Honey Shows Strong Antioxidant Potential

Monofloral honeys by Sicilian black honeybee (Apis mellifera ssp. sicula) have high reducing power and antioxidant capacity

Heliyon. 2016 Nov 10;2(11)

Thirty samples from thirteen Sicilian monofloral honeys by the local black honeybee, and two honeydew honeys, were studied to assess phenol content, reducing power and antioxidant capacity as well as correlations among these parameters.

Honeys from Apiaceae showed the highest phenol amount and capacity to reduce ferric ion and stable chemical radicals, whereas honeys from Leguminosae the lowest.

All honeys were active against myoglobin-derived radicals usually formed in red meat after storage and/or heating and significant correlation (p = 0.023) was found between flavonoid content and deactivation rate of this radical. Dill > almond > tangerine > thistle > sulla honeys inhibited formation of lipoperoxides in either iron/ascorbate or azoinitiator -induced membrane lipid oxidation, whereas eucalyptus honey was mostly effective in the metal-dependent model.

Honeys by black honeybee possess remarkable reducing power and antioxidant potential against radicals of interest in dietary foodstuffs.

Comparison of the Effects of Alpha and Medical-Grade Honey Ointments

A Comparison of the Effects of Alpha and Medical-Grade Honey Ointments on Cutaneous Wound Healing in Rats

J Pharm (Cairo). 2016;2016:9613908

Introduction. This study compared the healing efficacy and possible adverse effects of topical Alpha and medical-grade honey ointments on cutaneous wounds in rats.

Methods. To conduct the study, 22 male Sprague-Dawley rats were randomly allocated into two equal groups: (1) rats with Alpha ointment applied to the wound surface area and (2) rats with medical-grade honey ointment applied to their wounds. The ointments were applied daily during the 21-day study period. Wound contraction was examined photographically with images taken on days 0, 7, and 21 after wounding. The healing process was histopathologically assessed using skin biopsies taken from the wound sites on days 7 and 21.

Results. No statistically significant difference in mean wound surface area was observed between the two study groups. According to histopathological assessment, a significant reduction in the amount of collagen deposition (P value: 0.007) and neovascularisation (P value: 0.002) was seen in the Alpha-treated rats on day 21. No tissue necrosis occurred following the application of Alpha ointment.

Conclusion. Daily topical usage of Alpha ointment on a skin wound can negatively affect the healing process by inhibiting neovascularization. Topical Alpha ointment can reduce the possibility of excessive scar formation by reducing collagen deposition.

It’s a new type of facial that’s getting a lot of buzz, CBS2’s Emily Smith reported. The procedure uses bee venom and honey to tighten your skin and make it glow by tricking your body into thinking your face has been stung.

“Bee venom that sounds scary but once they got it they get addicted to the peel,” clinical aesthetician Julie Lindh said.

Here’s how it works. First, the skin is washed clean. Then, a bee venom potion is applied to the skin to help trigger the healing process, ultimately creating a collagen synthesis.

A second coat is then applied, creating a stronger burning sensation. Once application is complete, the client’s face is wrapped in gauze, locking in the concoction for around 10 minutes.

Honey Reduces Tonsillectomy Pain

Role of Honey after Tonsillectomy: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Clin Otolaryngol. 2016 Nov 12

BACKGROUND:

Honey reduced post-tonsillectomy pain, but its effects on awakening at night, inflammation and healing of the tonsillar fossa were controversial.

OBJECTIVES:

This systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated the effect of oral honey on pain, consumption of painkillers, awakening at night, healing of tonsillar fossa, and adverse effects in children after tonsillectomy.

METHODS:

A search of MEDLINE, EMBASE, SCOPUS, CINAHL and COCHRANE Collaboration library databases was performed without any restriction of publication year. The end date of search was June 30, 2016. The search was supplemented by search from Google, hand search of cross-references of selected articles and reviews, and contacting the authors of different studies. The inclusion criteria were RCTs comparing the effect of honey with control on different outcomes, in children after tonsillectomy.

CONCLUSIONS:

Honey improved pain, requirement of painkillers, and awakening at night due to pain in children after tonsillectomy. There was little improvement in healing of tonsillar fossa. The GRADE of the evidence varied from 'low' to 'very low'. A good quality, placebo controlled RCT of different doses and durations of administration of honey is required to evaluate its clear efficacy and safety in children after tonsillectomy.

Royal Jelly May Help Treat Inflammatory Diseases

In Vitro Anti-Inflammatory Effects of Three Fatty Acids from Royal Jelly

Mediators Inflamm. 2016;2016:3583684

Trans-10-hydroxy-2-decenoic acid (10-H2DA), 10-hydroxydecanoic acid (10-HDAA), and sebacic acid (SEA) are the three major fatty acids in royal jelly (RJ). Previous studies have revealed several pharmacological activities of 10-H2DA and 10-HDAA, although the anti-inflammatory effects and underlying mechanisms by which SEA acts are poorly understood.

In the present study, we evaluated and compared the in vitro anti-inflammatory effects of these RJ fatty acids in lipopolysaccharide-stimulated RAW 264.7 macrophages. The results showed that 10-H2DA, 10-HDAA, and SEA had potent, dose-dependent inhibitory effects on the release of the major inflammatory-mediators, nitric oxide, and interleukin-10, and only SEA decreased TNF-α production. Several key inflammatory genes have also been modulated by these RJ fatty acids, with 10-H2DA showing distinct modulating effects as compared to the other two FAs. Furthermore, we found that these three FAs regulated several proteins involved in MAPK and NF-κB signaling pathways. Taken together, these findings provide additional references for using RJ against inflammatory diseases.

Radical Scavenging Activity of Cameroonian Propolis

New mono-ether of glycerol and triterpenes with DPPH radical scavenging activity from Cameroonian propolis

Nat Prod Res. 2016 Nov 13:1-11

The extracts of some propolis samples were analysed by GC-MS and then purified by column chromatography. The latter led to the isolation of a new mono-ether of glycerol, 1'-O-eicosanyl glycerol and a new triterpene, methyl-3β,27-dihydroxycycloart-24-en-26-oate together with known triterpenoids namely betulin, 3β-hydroxylanostan-9,24-dien-21-oic acid, mangiferonic acid, a mixture of ambolic acid and β-sitosterol, 3β-hydroxycycloartan-12,24(25)-diene and 27-hydroxymangiferonic acid. The DPPH radical scavenging potential of some extracts and compounds were measured.

The radical scavenging activity varied from Hexane extract of Foumban propolis (IC50 = 5.6 mg/mL) to Methanol extract of Foumban propolis (IC50 = 1.07 mg/mL) for the extracts and from 3β-hydroxylanostan-9,24-dien-21-oic acid (IC50 = 1.22 mg/mL) to 1'-O-eicosanyl glycerol (IC50 = 0.93 mg/mL) for the compounds. Activities of samples were moderate as they remained closer to those of the standard antioxidants Gallic acid (IC50 = 0.30 mg/mL) and vitamin C (IC50 = 0.80 mg/mL), especially 1'-O-eicosanyl glycerol, the most active compound.
