Intestinal Linings Protected by Propolis from Radiation

New findings from this study reaffirms the protective effects of propolis from radiation exposure. This is quite impressive, as propolis is documented to work well on mucous linings of the body and protecting organs such as the liver, kidneys and spleen. This study builds upon the rich database of research which continues to reveal this substance as an essential adjuvant for patients undergoing radiation therapy. Furthermore, the anti-cancerous effects that propolis also provides should make physicians eager to incorporate propolis in their protocols.  

Propolis aqueous extract preserves functional integrity of murine intestinal mucosa after exposure to ionizing radiation

Environ Toxicol Pharmacol. 2015 Oct 9;40(3):901-906

Highlights: 

- Histological and biochemical evidence of intestinal damage seen after irradiation

- Parameters for intestinal function measured in tissue homogenates and plasma

- Propolis extract prevents histological and biochemical radiation-induced changes

- Beneficial effect of propolis water extract due mainly to caffeic acid derivatives

The ability of a specially prepared water propolis extract (PWE) to preserve the functional activity of the intestinal mucosa after radiation exposure was studied. PWE was given orally (650mg/kg) to rats five days prior to irradiation by 6Gy and continued for further two days. Rats were sacrificed 24h later, intestinal segments were examined histologically and homogenates were used to assess relevant biochemical parameters reflecting intestinal injury. Irradiation led to a rise in the histological damage score, a rise in tissue TNF-α and TBARS, and a decrease in sucrase, alkaline phosphatase, GSH and cholecystokinin as well as a decrease in plasma citrulline.

The findings reflect a decrease in intestinal functional activity. PWE preserved the intestinal integrity and largely protected against the changes induced in the histology damage score and all parameters measured, possibly as a result of the antioxidant and anti-inflammatory action of its caffeic acid content.

Dental Plaque Reduced with Propolis Toothpaste

Competing with propolis in the field of dentistry is tough. Propolis responds very well when in contact with mucous linings of the body. This super antioxidant also delivers antimicrobial, antifungal and antiseptic properties which make it very adaptable to numerous conditions found out of balance. A secret in finding good toothpaste is to look for the "propolis. If it's not brown, then it's not significant.

The antiplaque efficacy of propolis-based herbal toothpaste: A crossover clinical study

J Nat Sci Biol Med. 2015 Jul-Dec;6(2):364-8

BACKGROUND:

In recent years, herbal products have been suggested as an economic, safe and probably effective alternative for prevention and control of various oral diseases. But still there are some products which need to be evaluated. Of lately, Propolis is one such product. To assess and compare the efficacy of herbal dentifrice containing Propolis with Miswak and Colgate total toothpastes in controlling plaque formation.

MATERIALS AND METHODS: 

Propolia propolis herbal toothpaste

A double blind, randomized, crossover study design was conducted among thirty healthy dental students. After oral prophylaxis all subjects were given a washout product for one week period. Subjects were then made to brush with (washout product) for 1 minute followed by 1 minute brushing with assigned test product. The baseline MGMPI plaque scores were recorded. Subjects were then refrained from oral hygiene for 24 hours, and were recalled to be re-disclosed and re-measured for plaque formation. This procedure was repeated according to crossover design after a washout period of (2 week). Statistical tests used were Krukalwallis and Wilcoxon sign rank test.


RESULTS:
There was a significant difference in 24 hour score between the test products evaluated. When the change from baseline to 24 hours was analyzed, the test product Propolis resulted in a consistently and significantly (p < 0.05) lower MGMPI mean scores than the Colgate Total and Miswak toothpastes.

CONCLUSION: 

Propolis was found to be safe and effective in reducing plaque accumulation when compared to Miswak and Colgate total toothpaste.

Comparative effect of propolis of honey bee and some herbal extracts on Candida Albicans

Chinese Journal of Integrative Medicine, July 7 2015

Objective

To determine the effect of propolis on Candida albicans and to compare it with the effects of some other herbal extracts and antibiotics on this pathogenic fungi.

Methods

The extracts of propolis, Thymus vulgaris, Caryophillium aromaticus, Echinophora platyloba, Allium cepa and Cinnamomum zeylanicum were prepared and the antifungi effects of the extracts were examined on Candida albicans ATCC10231 using disc-diffusion assay and micro-broth dilution. The minimum fungicidal concentration (MFC) and minimum inhibitory concentrations (MIC) as well as inhibition zone were evaluated and the anti fungi effects of herbal extracts were compared with amphotricin B and nystatin at the times of 24, 48 and 72 h. Data analysis was performed using test.

Results

Obtained results showed that propolis extract with MIC90 and MFC equal to 39 and 65 µg/mL, respectively, possess the highest antifungal activity when compared with other studied extracts. The extracts of Allium cepa and Thymus vulgaris, with MFC of 169 and 137 µg/mL, respectively, showed the lowest effects on the fungi. Also nystatin and amphotericin B yielded better effects on the tested fungi compared with the effects of all studied extracts on Candida albicans.

Conclusions

Propolis extract is effective in controlling Candida albicans. However, the issue requires further investigation on samples in animals and performing toxicological examinations.

Royal Jelly Effective Against Antibiotic-Resistant Pneumonia

Royal Jelly possesses many documented bioactive properties and this study found that both fresh and freeze-dried royal jelly is effective against antibiotic-resistant pneumonia. Add this to the fact that it's also a brain-booster, hormone-regulator and an anti-aging compound, not to mention that it boosts red blood cell counts, glucose tolerance and mental health!

The Lyophilization Process Maintains the Chemical and Biological Characteristics of Royal Jelly

Evid Based Complement Alternat Med. April 2015

The alternative use of natural products, like royal jelly (RJ), may be an important tool for the treatment of infections caused by antibiotic-resistant bacteria. RJ presents a large number of bioactive substances, including antimicrobial compounds.

In this study, we carried out the chemical characterization of fresh and lyophilized RJ and investigated their antibacterial effects with the purpose of evaluating if the lyophilization process maintains the chemical and antibacterial properties of RJ. Furthermore, we evaluated the antibacterial efficacy of the main fatty acid found in RJ, the 10-hydroxy-2-decenoic acid (10H2DA).

S. pneumoniae in spinal fluid (digitally colored).

Chromatographic profile of the RJ samples showed similar fingerprints and the presence of 10H2DA in both samples. Furthermore, fresh and lyophilized RJ were effective against all bacteria evaluated; that is, the lyophilization process maintains the antibacterial activity of RJ and the chemical field of 10H2DA. The fatty acid 10H2DA exhibited a good antibacterial activity against Streptococcus pneumoniae.

Therefore, it may be used as an alternative and complementary treatment for infections caused by antibiotic-resistant S. pneumoniae.

Honey Bee Products Improve the Immune System

Yet another synergistic effect from consuming bee products. This is an important update to a previous study that identified lactic acid bacteria present in honey, bee pollen and bee bread. This human trial, even though small, reveals great promise for those needing immune system support, complementing the medical community's interest in the connection between the immune system and a healthy gut.

Lactobacillus kunkeei YB38 from honeybee products enhances IgA production in healthy adults

J Appl Microbiol. 2015 Jun 29. doi: 10.1111/jam.12889.

AIMS:
To identify lactic acid bacterial isolates that promote IgA production in honeybee products and honeybees (Apis mellifera).

METHODS AND RESULTS:
Pyrosequencing analysis of the microbiota of honeybee products and honeybees revealed the predominance of Lactobacillus kunkeei in honey, bee pollen, bee bread, and royal jelly. L. kunkeei was isolated from bee pollen, bee bread, and honey stomach, and its effect on IgA production was evaluated in vitro. Heat-killed YB38 and YB83 isolates from bee pollen promoted IgA production in mouse Peyer's Patch cells and had little mitogenic activity or effect on IL-2 production in mouse spleen cells in comparison with Listeria monocytogenes, which does exhibit mitogen activity. A pilot study in 11 healthy adults showed that 4-week intake of 1,000 mg/day heat-killed YB38 increased SIgA concentrations and secretion in saliva with no adverse effects.

CONCLUSION:
Heat-killed L. kunkeei YB38 from bee pollen increases IgA production and may safely improve immune responsiveness.

SIGNIFICANCE AND IMPACT OF THE STUDY:

This is the first report of microbiota analysis of royal jelly and the immune efficacy of L. kunkeei from honeybee products in humans.

Forest Honey Can Prevent Ulcers

Recognized world wide that honey is more than a food but also medicine, this new study finds these monofloral honeys to possess specialized healing properties, in particular concerning gastric ulcers. In fact, oak and chestnut honeys inhibit enzymes which cause gout, gastritis, cardiovascular disease and peptic ulcers.

Honey as an apitherapic product: its inhibitory effect on urease and xanthine oxidase

J Enzyme Inhib Med Chem. 2015 May 

The aim of this study was to evaluate new natural inhibitor sources for the enzymes urease and xanthine oxidase (XO). Chestnut, oak and polyfloral honey extracts were used to determine inhibition effects of both enzymes.

In addition to investigate inhibition, the antioxidant capacities of these honeys were determined using total phenolic content (TPC), ferric reducing antioxidant power (FRAP), and DPPH radical scavenging activity assays.

Due to their high phenolic content, chestnut and oak honeys are found to be a powerful source for inhibition of both enzymes. Especially, oak honeys were efficient for urease inhibition with 0.012-0.021 g/mL IC50 values, and also chestnut honeys were powerful for XO inhibition with 0.028-0.039 g/mL IC50 values.

Regular daily consumption of these honeys can prevent gastric ulcers deriving from Helicobacter pylori and pathological disorders mediated by reactive oxygen species.

Antioxidant Content in Propolis Protects Liver

Propolis provides a very good quantity of antioxidants and has important protective effects on internal organs, in particular the liver. This study confirms propolis reduced hypertension by preventing blood vessels from restricting blood flow even when under the influence of a drug that induces vasorestriction. A commonly found trait in propolis is its ability to protect and heal, along with anti-inflammatory and antimicrobial properties, it's an important adjuvant agent. 

Antioxidant Effect of Ethanolic Extract of Propolis in Liver of L-NAME Treated Rats

Adv Clin Exp Med. 2015 Mar-Apr

BACKGROUND:

The blocking of nitric oxide synthase (NOS) activity may cause vasoconstriction with formation of reactive oxygen species. Propolis is a natural product collected from plants by honeybees. Propolis has biological and pharmacological properties.

OBJECTIVES:

This study was designed to investigate the effects of propolis on catalase (CAT) activity, nitric oxide (NO) and malondialdehyde (MDA) levels in the liver tissues of NOS inhibited rats by Nω-Nitro-L-argininemethyl ester (L-NAME).

MATERIAL AND METHODS:

Rats were given a NOS inhibitor (L-NAME, 40 mg/kg, intraperitoneally) for 15 days to provoke hypertension and propolis (200 mg/kg, by gavage) the last 5 of the 15 days.

RESULTS:

Nitric oxide levels in the liver tissue of the rats given L-NAME significantly

decreased (p < 0.01). That parameter did not significantly alter in the liver of rats treated with propolis compared to the control group. CAT activity and MDA levels in the liver of the rats administrated L-NAME significantly increased compared to the control group (p < 0.01). These parameters significantly decreased in the liver of the rats given L-NAME + propolis compared to the L-NAME group (p < 0.01).

CONCLUSIONS:

The present data shows that L-NAME in the liver may enhance oxidative stress via inhibited nitric oxide synthase. Our results also suggest that this effect is suppressed by the antioxidant properties of propolis in the liver tissue of NOS inhibited rats.
