Component of Honey, Propolis Protects Against Cell Damage

Chrysin, a flavonoid attenuates histological changes of hyperammonemic rats: A dose dependent study

Biomed Pharmacother. 2016 May 24;82:345-354

Chrysin (5,7-dihydroxyflavone) is a major component of some traditional medicinal herbs present in honey, propolis and many plant extracts.

The study was aimed to illuminate the effect of chrysin in the pathogenesis of ammonium chloride (NH4Cl) induced hyperammonemic rat model in a dose dependent manner. Rats were injected with NH4Cl (100mg/kg b.w.) by intraperitonially (i.p) thrice a week for 8 consecutive weeks for the induction of experimental hyperammonemia. Hyperammonemic rats were treated with chrysin by orally at a dose of 25, 50 & 100mg/kg b.w. respectively. Protective effect of chrysin against hyperammonemia was evaluated by performing biochemical estimations and morphopathological investigations of hematoxylin and eosin stained sections of liver, brain and kidney tissues. Supplementation of chrysin reinstated the levels of blood ammonia, plasma urea, uric acid, total bilirubin, creatinine, brain glutamate, glutamine, nitric oxide (NO) and the activities of Na+/K+-ATPase, and liver marker enzymes. On the other hand increased level of plasma urea was observed in chrysin treated rats as compared with hyperammonemic rats. Chrysin administration caused distortion of hepatic, brain and kidney architecture as shown by histological examination.

Chrysin at a dose (100mg/kg b.w.) showed an utmost decline in the level of all biochemical estimations. Both biochemical and morphological studies clearly revealed that chrysin protects against cell injury induced by ammonia intoxication in a dose-response manner with respect to endogenous antioxidants and hypoammonemic effects.

Honey Treats Children's Cough Better Than OTC Treatments

Efficacy and tolerability of a polysaccharide-resin-honey based cough syrup as compared to carbocysteine syrup for children with colds: a randomized, single-blinded, multicenter study

World J Pediatr. 2016 Jul 23. [Epub ahead of print]

BACKGROUND:

Available pediatric treatments for acute cough are limited by lack of demonstrated efficacy. The objective of this trial is to compare the effects of a polysaccharide-resin-honey based cough syrup, and carbocysteine syrups on nocturnal and daytime cough associated with childhood upper respiratory tract infections (URIs).

METHODS:

Using a single-blind randomization design, the study recruited children from 4 general pediatric community clinics. Participants included 150 children aged 2 to 5 years with an URI, nocturnal and daytime cough and illness duration of ≤7 days. To be eligible, children had to be free of medication on the day before presentation. A survey was administered to parents on 4 consecutive days beginning from the day of presentation in clinic. Children received the study preparation on the first evening and then 3 times per day for 3 further days. Main outcome measures were cough frequency, cough severity, bothersome nature of cough, and quality of sleep for both child and parent.

RESULTS:

Both preparations were well tolerated and cough improved over the study period. After one night and on all survey days, there was a significantly better result for polysaccharide-resin-honey.

Royal Jelly May Help Treat Alzheimer’s Disease

Royal jelly promotes DAF-16-mediated proteostasis to tolerate β-amyloid toxicity in C. elegans model of Alzheimer’s disease

Oncotarget, Published: July 26, 2016

ABSTRACT

Numerous studies have demonstrated that dietary intervention may promote health and help prevent Alzheimer’s disease (AD). We recently reported that bee products of royal jelly (RJ) and enzyme-treated royal jelly (eRJ) were potent to promote healthy aging in C. elegans.

Here, we examined whether RJ/eRJ consumption may benefit to mitigate the AD symptom in the disease model of C. elegans. Our results showed that RJ/eRJ supplementation significantly delayed the body paralysis in AD worms, suggesting the β-amyloid (Aβ) toxicity attenuation effects of RJ/eRJ. Genetic analyses suggested that RJ/eRJ-mediated alleviation of Aβ toxicity in AD worms required DAF-16, rather than HSF-1 and SKN-1, in an insulin/IGF signaling dependent manner. Moreover, RJ/eRJ modulated the transactivity of DAF-16 and dramatically improved the protein solubility in aged worms. Given protein solubility is a hallmark of healthy proteostasis, our findings demonstrated that RJ/eRJ supplementation improved proteostasis, and this promotion depended on the transactivity of DAF-16.

Collectively, the present study not only elucidated the possible anti-AD mechanism of RJ/eRJ, but also provided evidence from a practical point of view to shed light on the extensive correlation of proteostasis and the prevention of neurodegenerative disorders.

Royal Jelly May Help Control Hypertension (High Blood Pressure)


Functional and Proteomic Investigations Reveal Major Royal Jelly Protein 1 Associated with Anti-hypertension Activity in Mouse Vascular Smooth Muscle Cells

Sci Rep. 2016 Jul 22;6:30230

Vascular smooth muscle cells (VSMCs) are a major cell type of the arterial wall and their functionality is associated with blood pressure regulation. Although royal jelly (RJ) has reported effects on anti-hypertension, the mechanism of blood pressure regulation by major royal jelly protein 1 (MRJP1), the most abundant RJ protein, is still unknown.

The mrjp1 gene was inserted into mouse VSMCs to investigate how MRJP1 influences VSMC functionality by functional and proteomic analysis. The expression of MRJP1 in VSMCs significantly reduced cell contraction, migration, and proliferation, suggesting a potential role in decreasing hypertension via action on VSMCs.

These anti-hypertension activities were further observed in the changes of the proteome setting of mouse VSMCs. Among 675 different proteins after MRJP1 expression, 646 were down-regulated and significantly enriched in pathways implicated in VSMC contraction and migration, which suggest MRJP1 lowers VSMC contraction and migration by inhibiting muscle filament movement. The down-regulated proteins also enriched pathways in proliferation, indicating that MRJP1 hinders VSMC proliferation by reducing the supply of energy and genetic material.

This is the first report integrating MRJP1 into VSMC, revealing the function and mechanism correlated with anti-hypertensive activity. This offers a therapeutic potential to control hypertension by gene-therapy using bee-products.

Bee Venom Was Used in Ancient Greece, China and Egypt

The Healing Power of Venom

Wall Street Journal

July 22, 2016

Humans have been toying with this idea for centuries. One of the earliest treatments for ailments from gout to baldness was apitherapy, the medical application of bee venom, which was used in ancient Greece, China and Egypt. The ancient Greeks associated snakes and their venoms with medicine through the god Asclepius, whose followers prescribed venoms as cures and whose staff had a snake wrapped around it—the inspiration for the well-known symbol of medicine today.

Honey May Help Prevent Cancer Due to Antioxidant Activity

Histopathological and biochemical investigations of protective role of honey in rats with experimental aflatoxicosis

BMC Complement Altern Med. 2016 Jul 21;16(1):232

BACKGROUND:

Natural honey (honey) is considered as a part of traditional medicine all over the world. It has both antimicrobial and antioxidant properties, useful in stimulation of wounds and burns healing and gastric ulcers treatment. The aim of this study, for the first time, was to investigate the antioxidant properties and protective role of honey against carcinogen chemical aflatoxin (AF) exposure in rats, which were evaluated by histopathological changes in liver and kidney, measuring level of serum marker enzymes [aspartate aminotransferase (AST), alanin aminotransferase (ALT), gamma glutamil transpeptidase (GGT)], antioxidant defense systems [Reduced glutathione (GSH), glutathione reductase (GR), superoxide dismutase (SOD), glutathione-S-transferase (GST) and catalase (CAT)], and lipid peroxidation content in liver, erythrocyte, brain, kidney, heart and lungs.

METHODS:

Eighteen healthy Sprague-Dawley rats were randomly allocated into three experimental groups: A (Control), B (AF-treated) and C (AF + honey-treated). While rats in group A were fed with a diet without AF, B, and C groups received 25 μg of AF/rat/day, where C group additionally received 1 mL/kg of honey by gavage for 90 days.

RESULTS:

At the end of the 90-day experimental period, we found that the honey supplementation decreased the lipid peroxidation and the levels of enzyme associated with liver damage, increased enzymatic and non-enzymatic antioxidants in the AF + honey-treated rats. Hepatoprotective and nephroprotective effects of honey is further substantiated by showing almost normal histological architecture in AF + honey-treated group, compared to degenerative changes in the liver and kidney of AF-treated rats. Additionally, honey supplementation ameliorated antioxidant defens systems and lipid peroxidation in content in other tissues of AF + honey treated rats.

CONCLUSION:

The present study indicates that honey has a hepatoprotective and nephroprotective effect in rats with experimental aflatoxicosis due to its antioxidant activity.

Chestnut Honey Shows Antioxidant, Antimicrobial Activity

A comparative study of the antihyaluronidase, antiurease, antioxidant, antimicrobial and physicochemical properties of different unifloral degrees of chestnut (Castanea sativa Mill.) honeys

J Enzyme Inhib Med Chem. 2016 Jul 20:1-9

This study was planned to investigate some physicochemical and anti-inflammatory, antioxidant, antimicrobial properties of three different degrees of unifloral characters of chestnut honeys.

Antihyaluronidase, antiurease and antimicrobial activities were evaluated as anti-inflammatory characteristics. Total phenolic contents, flavonoids, tannins, phenolic profiles, ferric-reducing antioxidant power (FRAP), scavenging activities of 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS+) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals were evaluated as antioxidant properties. Color, optical rotation, conductivity, moisture, pH and ash content were evaluated as physicochemical parameters, and some sugars content, prolin, diastase, HMF and minerals (Na, K, Ca, P, Fe, Cu and Zn) were evaluated as chemical and biochemical parameters.

All studied physicochemical and biological active properties were changed in line with the unifloral character of the chestnut honeys. A higher unifloral character was found associated with greater apitherapeutic capacity of the honey, as well as biological active compounds.

Gelam Honey and Ginger May Help Treat Colorectal Cancer

Mechanism of Chemoprevention against Colon Cancer Cells Using Combined Gelam Honey and Ginger Extract via mTOR and Wnt/β-catenin Pathways

Asian Pac J Cancer Prev. 2015;16(15):6549-56

The PI3K-Akt-mTOR, Wnt/β-catenin and apoptosis signaling pathways have been shown to be involved in genesis of colorectal cancer (CRC).

The aim of this study was to elucidate whether combination of Gelam honey and ginger might have chemopreventive properties in HT29 colon cancer cells by modulating the mTOR, Wnt/β-catenin and apoptosis signaling pathways. Treatment with Gelam honey and ginger reduced the viability of the HT29 cells dose dependently with IC50 values of 88 mg/ml and 2.15 mg/ml respectively, their while the combined treatment of 2 mg/ml of ginger with 31 mg/ml of Gelam honey inhibited growth of most HT29 cells.

Gelam honey, ginger and combination induced apoptosis in a dose dependent manner with the combined treatment exhibiting the highest apoptosis rate. The combined treatment downregulated the gene expressions of Akt, mTOR, Raptor, Rictor, β-catenin, Gsk3β, Tcf4 and cyclin D1 while cytochrome C and caspase 3 genes were shown to be upregulated.

In conclusion, the combination of Gelam honey and ginger may serve as a potential therapy in the treatment of colorectal cancer through inhibiton of mTOR, Wnt/β catenin signaling pathways and induction of apoptosis pathway.

Active Leptospermum Honey a 'Valuable' Treatment for Partial-Thickness Facial Burns

A Pilot Study of the Efficacy of Active Leptospermum Honey for the Treatment of Partial-Thickness Facial Burns

Adv Skin Wound Care. 2016 Aug;29(8):349-355

OBJECTIVE:

Research suggests that active Leptospermum honey (ALH) improves outcomes in patients with partial-thickness burns by enhancing healing and reepithelialization rates, as well as by protecting against antibiotic-resistant microorganisms. This study assessed the effectiveness of ALH gel on healing time, bacterial growth, patient satisfaction, and cost of treatment.

DESIGN:

Single-arm, prospective case series.

SETTING AND PATIENTS:

Seven patients (aged 7-64 years) with partial-thickness facial burns were recruited from a northeastern US burn center.

INTERVENTION:

All patients cleansed their wounds daily with soap and water, after which they applied ALH gel.

MAIN OUTCOME MEASURES:

Three physicians independently rated healing using wound photography and daily tests for the presence of exudate. Wound cultures on days 1 and 7 (±2 days) assessed bacterial growth. Patients completed a satisfaction survey at the end of treatment, and cost of treatment was calculated.

MAIN RESULTS:

Healing time ranged from 3 to 14 days (mean, 8.1 days). Wound cultures revealed normal bacterial growth on days 1 and 7 for all patients. Patients rated ALH gel favorably, with the most common complaint of stickiness in 5 patients. One patient experienced transient burning on application that did not interrupt treatment. Average hospital-based cost of treatment was $26.15 per patient.

CONCLUSIONS:

Healing time was congruent with or better than what would have been expected with standard treatment. Furthermore, despite no antibiotic treatment, wound culture results yielded no abnormal bacterial growth. Finally, patients overall reported satisfaction with treatment. The findings of this study suggest that ALH is a clinically and economically valuable treatment for partial-thickness facial burns.

Propolis May Help Treat Chronic Rhinosinusitis

The Effect of Propolis in Healing Injured Nasal Mucosa: An Experimental Study

Int Arch Otorhinolaryngol. 2016 Jul;20(3):222-5

INTRODUCTION:

Mechanical trauma to the nasal mucosa increases the risk of synechia formation, especially after chronic rhinosinusitis and nasal surgeries.

OBJECTIVE:

This study was carried to assess the effect of propolis administration in healing injured nasal mucosa in rats.

METHODS:

We randomly divided eighteen rats into three equal experimental groups: (1) non-treated group; (2) gum tragacanth (suspending agent for propolis) treated group; and (3) propolis treated group. The non-treated group received no treatment for 15 days. The second group received gum tragacanth administration (5 ml/kg, orally) once daily for 15 days. The third group received propolis suspension orally at a dose of 100 mg/kg once daily for 15 days. At the beginning of this study, we induced unilateral mechanical nasal trauma on the right nasal mucosa of all rats in the three groups using a brushing technique. A pathologist stained tissue samples using hematoxylin and examined eosin by using a light microscope.

RESULTS:

The severity of inflammation was milder with the absence of ulcerations in the propolis treated group compared with the non-treated and gum tragacanth groups. Goblet cell and ciliated cell loss was substantially lower in patients treated with propolis compared with groups without treatment and those treated with gum tragacanth.

CONCLUSION:

Propolis decreased inflammation and enhanced healing of wounds of the nasal mucosa in rats

Propolis, Bee Venom May Help Treat Schistosomiasis

Effect of bee venom or proplis on molecular and parasitological aspects of Schistosoma mansoni infected mice

J Parasit Dis. 2016 Jun;40(2):390-400

The present study was performed to elucidate the efficacy of Apis mellifera L bee venom (BV) or proplis (200 mg/kg orally for three consecutive days) on Schistosoma mansoni infected mice.

The results recorded reduction in the total worm burden, numbers of immature eggs and the ova count in hepatic tissue in BV (sting or injection) or proplis treated groups as compared to the infected group.

Histological examination illustrated a significant increase (P ≤ 0.05) in the diameter of hepatic granuloma in BV treated groups (272.78 and 266.9, respectively) and a significant decrease in proplis treated mice (229.35) compared with the infected group (260.67). Electrophoretic pattern of RNA showed a decrease in mean of maximal optical density in liver and intestine of S. mansoni infected mice treated with bee venom (sting or injection) as compared with infected group. Flow cytometry analyses of RNA or apoptotic percentage of worms recovered from BV sting (19 and 49 % respectively); BV injected (20.5 and 51.17 %, respectively) and proplis (35 and 23.93 %, respectively) groups were compared with S. mansoni infected group (37.87 and 39.21 %, respectively).

It can be concluded that administration of bee venom or proplis are effective in case of S. mansoni infection. Although bee venom cause increase of granuloma diameter and this might be due to venom concentration and further studies are required to avoid such harmful effect.
