Propolis Helps Treat Oral Cavity Diseases

Propolis, A Hope for the Future in Treating Resistant Periodontal Pathogens

Cureus. 2016 Jul 12;8(7):e682

INTRODUCTION:

Periodontitis is one of the most common causes of tooth loss worldwide. Recently, special attention has been paid to natural medication for its treatment. For this purpose, propolis (bee glue) activity has also been investigated. Its antibacterial properties are mainly attributed to flavonones pinocembrin, flavonols galangin and to the caffeic acid phenethyl ester. This study is aimed at evaluating the antimicrobial effects of propolis from Pakistan on 35 clinical isolates of pigmented anaerobic periodontal pathogens.

METHODS:

This study was conducted in the Microbiology department, University of Health Sciences, Lahore, Pakistan. Pathogens included were Porphyromonas asaccharolytica (n=9), Porphyromonas gingivalis (n=13), Prevotella intermedia (n=9), Prevotella melaninogenica (n=4). Minimum inhibitory concentration (MIC) to three antibiotics was obtained by E-test method. All strains were sensitive to amoxicillin plus clavulanic acid and metronidazole, but 100% of P asaccharolytica and P melaninogenica strains displayed intermediate resistance to tetracycline while 69.2% P gingivalis and 100% P intermedia strains exhibited complete resistance to tetracycline. Screening for antibacterial activity of propolis extract was done by agar well diffusion assay, and all strains were found sensitive to ethanolic extract of propolis.

RESULTS:

MIC was obtained by agar incorporation technique with values ranging from 0.064 to 0.512 mg/ml. It was also noticed that percentage yield of ethanolic extract of propolis prepared from ultrasonic extraction method was higher compared to extract obtained with maceration.

CONCLUSION:

These results indicate that propolis from this region has potent antimicrobial activity against pigmented anaerobic periodontal pathogens. Taking into consideration the increasing resistance in anaerobic bacteria, this effective antimicrobial activity of propolis gives hope in the treatment of oral cavity diseases.

Anti-Inflammatory Activity of Bee Venom Studied

Anti-Inflammatory Activity of Bee Venom in BV2 Microglial Cells: Mediation of MyD88-Dependent NF-κB Signaling Pathway

Evid Based Complement Alternat Med. 2016;2016:3704764

Bee venom has long been used as a traditional folk medicine in Korea. It has been reportedly used for the treatment of arthritis, cancer, and inflammation. Although its anti-inflammatory activity in lipopolysaccharide- (LPS-) stimulated inflammatory cells has been reported, the exact mechanism of its anti-inflammatory action has not been fully elucidated.

Therefore, the aim of this study was to investigate the anti-inflammatory mechanism of bee venom in BV2 microglial cells. We first investigated whether NO production in LPS-activated BV2 cells was inhibited by bee venom, and further iNOS mRNA and protein expressions were determined. The mRNA and protein levels of proinflammatory cytokines were examined using semiquantitative RT-PCR and immunoblotting, respectively. Moreover, modulation of the transcription factor NF-κB by bee venom was also investigated using a luciferase assay. LPS-induced NO production in BV2 microglial cells was significantly inhibited in a concentration-dependent manner upon pretreatment with bee venom. Bee venom markedly reduced the mRNA expression of COX-2, TNF-α, IL-1β, and IL-6 and suppressed LPS-induced activation of MyD88 and IRAK1 and phosphorylation of TAK1. Moreover, NF-κB translocation by IKKα/β phosphorylation and subsequent IκB-α degradation were also attenuated.

Thus, collectively, these results indicate that bee venom exerts its anti-inflammatory activity via the IRAK1/TAK1/NF-κB signaling pathway.

Honey, Propolis and Bee Pollen Human Carbonic Anhydrase

Investigation of the inhibitory properties of some phenolic standards and bee products against human carbonic anhydrase I and II

J Enzyme Inhib Med Chem. 2016 Aug 25:1-6

Polyphenols are important secondary products of plants with the potential to inhibit carbonic anhydrases. The aim of this study was to investigate the inhibition effects of various phenolic standards, honey, propolis, and pollen species on human carbonic anhydrase I and II. The inhibition values (IC50) of the phenolics (gallic acid, protocatechuic acid, quercetin, catechin, tannic acid, and chrysin) ranged from 0.009 to 0.32 μg/mL, tannic acid emerging as the best inhibitor.

The inhibition values of three different types of honey, heather, rhododendron, and chestnut ranged between 2.32 and 25.10 μg/mL, the chestnut honeys exhibiting the best inhibition. The ethanolic extracts of pollen and propolis exhibited good inhibitory properties, with IC50 values between 0.486 and 3.320 μg/mL. In order to evaluate the phenolic composition of bee products, phenolic profiles and total phenolic contents (TFC) were also measured. The inhibition ranking among the natural products studied was phenolic standards > propolis > pollen > honeys, and inhibition was related to TFC.

There's a Battle to Trademark Manuka, the Champagne of Honeys


Bloomberg, 8/24/2016

There's a fight Down Under over manuka honey, the so-called superfood famed for its antibacterial qualities. On one side, New Zealand beehive owners say they should have exclusive rights to the manuka name. On the other, Australian producers say the manuka tree that gives the sticky stuff its name is an Aussie native and their honey is just as super as its Kiwi cousin.

Does Natural Honey-Containing Fructose have Benefits to Diabetic Patients?

Malaysian Journal of Medical Sciences 23(2):86 · March 2016

A  systematic  review  and  meta-analysis  by Cozma  et  al.  (4)  resulted  in  some  important findings  with  respect  to  the effect  of fructose  in diabetic  patients.  The  authors  concluded  that compared  to  other  carbohydrates,  fructose  has greater long term benefits for improving glycemic control  and  has no  effect on  insulin  and fasting glucose.  Moreover,  unlike  the  work  of  Bahrami et  al.  (3),  this  study  showed  improvements  in HbA1c levels as a result of fructose consumption. However,  this  review  has  several  limitations, including the short duration (less than 12 weeks) and relatively low quality of most trials analyzed. Thus, larger and longer studies are recommended.

Qairooti (Cerate or Cera Beeswax Salve) in Traditional Iranian Pharmacy

Iran J Med Sci. 2016 May;41(3):S8

BACKGROUND:

Qairooti (Cerate), a medicinal salve or ointment, compounded of wax and oil, is a formulation used alone or as a basis for medicinal dosage forms. It is widely used from the ancient times to the present. Based on its structure, beeswax has unique characteristics. It builds stable emulsions and increases water absorbance of creams and ointments. The aim of this study was to gather all pharmaceutical information about preparing Qairooti products from traditional pharmacopoeaes, such as the various types of Qairooti and their preparation methods.

METHODS:

In this article, various types of Qairooti, their producing method and related indications have been discussed based on the main medical Persian manuscripts including Al-Canon fil tibb (Canon of Avicenna), Gharabadin-e-Kabir, Gharabadin-e-Salehi, Exir-e-Azam, Alhavi, Kamel-al-sanaat, Zakhireh-ye Khwarazm shahi, al-Shamel-fi-sanawat-al-tebie, Ekhtiarate badiee, Kholasat-al-tajarob, Tib-e-Akbari, Mofareh al-gholoob, Makhzan-ul-Adwiah, Hedayat-al-motealemin-fi-al-tibb, Altasrif-le-man-ajeza-an-talif, etc.

RESULTS:

About 500 different formulations from the above-mentioned manuscripts were found and their preparation method and other required information were collected. The amounts of oil and wax in Qairooti are not fixed and depend on different factors; providing the best consistency and appearance of the formulation, such as seasonal temperature. In order to prepare cerate, wax has to be melted by indirect heat and then mixed with the isothermal oil. Mixing process should be performed precisely to provide a homogenized product. If the multi-ingredient cerate is needed, other constituents have to be added to the warm mixture of oil and wax.

CONCLUSION:

There are many kinds of Qairooti in traditional Iranian pharmacopoeias recommended for different indications. Cerate was a common medication for injuries and wounds. Although it is still used in conventional medicine, some clinical applications in traditional Iranian medicine have been forgotten nowadays. It is recommended that we have a smarter approach to the traditional pharmacopoeias in order to use past experience and transcend existing knowledge of modern pharmacy.

Tester Microorganisms for Power of Medicinal Honeys

Honey sensitive Pseudomonas aeruginosa mutants are impaired in catalase A

Microbiology. 2016 Aug 9

The antimicrobial power of honey seems to be ascribable to several factors, including oxidative and osmotic stress. The aim of this study was to find genetic determinants involved in the response to honey stress in the opportunistic pathogen Pseudomonas aeruginosa, chosen as model microorganism.

A library of transposon mutants of P. aeruginosa PAO1 was constructed and only four mutants unable to grow in presence of fir honeydew honey were selected. All four mutants were impaired in the major H2O2-scavenging enzyme catalase A (Kat A). The knock-out of katA gene caused sensitivity, as expected, to hydrogen peroxide, but also to different types of honey including Manuka GMO 220 honey. Genetic complementation, as well as the addition of PAO1 supernatant containing extracellular catalase, restored tolerance to honey stress in all the mutants.

As P. aeruginosa PAO1 catalase Kat A copes with H2O2 stress, it is conceivable that the antimicrobial activity of honey is, at least partially, due to the presence of hydrogen peroxide in honey or the ability of honey to induce production of hydrogen peroxide.

The katA deficient mutants could be used as tester microorganisms to compare the power of different types of natural and curative honeys in eliciting oxidative stress mediated by hydrogen peroxide.

Difficulty of Establishing a Uniform Quality Standard for Propolis from Diverse Geographical Origins

Comparative Study of Chemical Composition and Biological Activity of Yellow, Green, Brown, and Red Brazilian Propolis

Evid Based Complement Alternat Med. 2016;2016:6057650

The chemical composition and biological activity of a sample of yellow propolis from Mato Grosso do Sul, Brazil (EEP-Y MS), were investigated for the first time and compared with green, brown, and red types of Brazilian propolis and with a sample of yellow propolis from Cuba.

Overall, EEP-Y MS had different qualitative chemical profiles, as well as different cytotoxic and antimicrobial activities when compared to the other types of propolis assessed in this study and it is a different chemotype of Brazilian propolis.

Absence of phenolic compounds and the presence of mixtures of aliphatic compounds in yellow propolis were determined by analysing (1)H-NMR spectra and fifteen terpenes were identified by GC-MS. EEP-Y MS showed cytotoxic activity against human tumour strain OVCAR-8 but was not active against Gram-negative or Gram-positive bacteria.

Our results confirm the difficulty of establishing a uniform quality standard for propolis from diverse geographical origins. The most appropriate pharmacological applications of yellow types of propolis must be further investigated.

Bee Venom Used to Treat Musculoskeletal Disease in Korea

Usage report of pharmacopuncture in musculoskeletal patients visiting Korean medicine hospitals and clinics in Korea

BMC Complement Altern Med. 2016 Aug 17;16(1):292

BACKGROUND:

Pharmacopuncture is a relatively new acupuncture therapy combining acupuncture with herbal medicine. While pharmacopuncture is applied extensively in Korean medicine treatment, there are no clinical reports regarding what types of pharmacopuncture are used for which diseases.

METHODS:

Data was extracted retrospectively from the electronic medical records of all inpatients and outpatients at 12 Korean medicine hospitals and clinics during the period of December 17, 2010 to October 2, 2014. Treatment patterns for acupuncture, electroacupuncture and pharmacopuncture were analyzed. Principle diagnosis codes, frequency of treatment, pharmacopuncture type and costs were investigated to assess pharmacopuncture use in clinical settings.

RESULTS:

During the study period, a total 33,415 inpatients and 373,755 outpatients visited the study sites, and most were musculoskeletal. Among inpatients and outpatients, 98.6 % and 77.6 % received pharmacopuncture, respectively. Administration rate of pharmacopuncture for the 10 most frequent principle diagnosis codes was 97.2-99.3 % in inpatients, and that for outpatients was 73.0-91.5 %. The average number of pharmacopuncture sessions in pharmacopuncture recipients was 8.2 ± 12.3 for outpatients and 25.8 ± 18.7 for inpatients. The mean total cost for pharmacopuncture per patient was $556.24 ± 174.62 among inpatients, and $149.16 ± 243.85 among outpatients. Estimated average cost per pharmacopuncture session was $23-24 for inpatients, and $17-18 for outpatients. Shinbaro1, bee venom, Hwangryunhaedok, and Shinbaro2 were the most frequently used pharmacopuncture types.

CONCLUSIONS:

This is the first analysis of treatment patterns of pharmacopuncture in a large-scale Korean medicine hospital/clinic patient population. We verified patterns of pharmacopuncture use for musculoskeletal disease treatment in Korea, and use of pharmacopuncture varied depending on disease or symptom severity. These results are expected to contribute to future clinical study design and standardization of pharmacopuncture.

Kelulut Stingless Bee Honey May Protect Against Colon Cancer

Chemopreventive Properties and Toxicity of Kelulut Honey in Sprague Dawley Rats Induced with Azoxymethane

Biomed Res Int. 2016;2016:4036926

Ethnopharmacological Relevance. Colon cancer has been a major problem worldwide. Kelulut honey (KH) is produced by the stingless bees from Trigona species and has strong antioxidant activities that could be one of the potential chemopreventive agents from natural resources.

Aim of This Study. This study investigated the chemopreventive properties and toxicity of KH in Sprague Dawley rats induced with azoxymethane (AOM).

Material and Method. Twenty-four male Sprague Dawley rats aged 5 weeks were divided into 4 groups: (G1) untreated group not induced with AOM, (G2) untreated group induced with AOM, (G3) treated group induced with AOM, and (G4) treated group not induced with AOM. Injection of AOM (15 mg/kg) was via intraperitoneal route once a week for two subsequent weeks. The treatment groups were given oral administration of KH (1183 mg/kg body weight) twice daily for 8 weeks.

Results. Treatment with KH significantly reduced the total number of aberrant crypt foci (ACF) and aberrant crypts (AC) and crypt multiplicity. KH was not toxic to the animals since the level of blood profile parameters, liver enzymes, and kidney functions was in normal range.

Conclusions. The current finding shows that KH has chemopreventive properties in rats induced with colorectal cancer and also was found not toxic towards the animals.

Citrus and Thyme Honeys Have Low GI

Glycemic index values of monofloral Turkish honeys and the effect oftheir consumption on glucose metabolism

Turk J Med Sci. 2016 Feb 17;46(2):483-8

BACKGROUND/AIM:

Clinical trials have shown that low glycemic index (GI) nutrition reduces mean blood glucose concentrations and insulin secretions. The aim of the present study was to determine the GI values of various monofloral (citrus, milk-vetch, chestnut, thyme, lime, pine) honeys of Turkey, and the effect of their consumption on glucose metabolism.

MATERIALS AND METHODS:

Processing data from 20 healthy volunteers, GI values were determined from the glycemia values by using the incremental area method. Serum insulin and C-peptide levels were also measured before and 120 min after the test.

RESULTS:

The GI values of citrus, thyme, lime, chestnut, pine, and milk-vetch honeys were found to be 44.9, 52.6, 55.3, 55.5, 58.8, and 69, respectively. Serum insulin and C-peptide values after honey consumption were relatively lower than those after reference food (glucose) consumption. By the end of the 120 min, serum insulin levels were significantly higher, while a significant decrease was observed after the consumption of chestnut honey (P < 0.05).

CONCLUSION:

Citrus and thyme honeys were determined to have low GI, while serum insulin levels were significantly lower after the consumption of chestnut honey. Long-term research is needed to compare the effects of honey consumption on healthy and diabetic individuals.

Honey, Propolis, Pollen, and Royal Jelly Significantly Enhance Healing of Liver

Apitherapy products enhance the recovery of CCL4-induced hepatic damages in rats

Turk J Med Sci. 2016 Jan 5;46(1):194-202

BACKGROUND/AIM:

Our objective was to identify the antioxidant properties of honeybee products from Turkey, chestnut honey, pollen, propolis, and royal jelly, and their hepatoprotective activity against CCl4-induced hepatic damage in rats.

MATERIALS AND METHODS:

Animals were fed with honeybee products for 7 days following CCl4 injection. Development of liver damage and oxidative stress were monitored by measuring the activities of the enzymes alanine transaminase, aspartate transaminase, malondialdehyde, superoxide dismutase, and catalase. Antioxidant capacities of the bee products were identified using FRAP and DPPH assays, as well as by measuring total phenolic and flavonoid contents.

RESULTS:

The antioxidant activities of the honeybee products were highest in propolis, followed, in order, by pollen, honey, and royal jelly. Despite their different levels of antioxidant capacity, their roles in the prevention of liver damage induced by CCl4 were very similar, which can be explained through their bioavailability to the treated animals.

CONCLUSIONS:

Our results suggest that honey, propolis, pollen, and royal jelly significantly enhanced the healing of CCl4-induced liver damage, partially due to their antioxidant properties and bioavailability.

Honeydew, Chestnut and Lime Tree Honeys Show Greatest Antimicrobial Activity

Evaluation of antimicrobial activity of Italian honey for wound healing application in veterinary medicine

Schweiz Arch Tierheilkd. 2016 Jul;158(7):521-527

Honey as a topical treatment for infected wounds dates back to ancient times. However, few studies have been reported concerning the medical properties of Italian honey.

In this study, the microbial contamination, the antimicrobial activity and the antibiotic residues of 6 different varieties of Piedmont honeys were evaluated. The antimicrobial activity of honeys was tested by agar well diffusion method and 1 honey for each variety has been selected and tested by broth micro-dilution test to determine Minimum Inhibitory Concentrations (MICs) and evaluated by Minimum Bactericidal Concentrations (MBCs). The honeys with a high level of antibacterial activity were analyzed for the presence of tetracyclines, sulfonamides and macrolide residues.

The agar well diffusion method showed the greatest antimicrobial activity for honeydew, chestnut and lime tree honeys. The MICs and MBCs identified the close similarity to the medical manuka honey of honeydew, polyfloral and chestnut honey. The levels of antibiotic residues on these honeys were below the limit of quantification. Based on our results the Italian variety of honeydew showed the best antimicrobial activity and can be considered for the treatment of infected wounds in animals.
