Abstract
Nowadays, in people's perceptions, the return to roots in all aspects of life is an increasing temptation. This tendency has also been observed in the medical field, despite the availability of high-level medical services with many years of research, expertise, and trials. Equilibrium is found in the combination of the two tendencies through the inclusion of the scientific experience with the advantages and benefits provided by nature. It is well accepted that the nutritional and medicinal properties of honey are closely related to the botanical origin of the plants at the base of honey production. Despite this, people perceive honey as a natural and subsequently a simple product from a chemical point of view. In reality, honey is a very complex matrix containing more than 200 compounds having a high degree of compositional variability as function of its origin. Therefore, when discussing the nutritional and medicinal properties of honey, the importance of the geographical origin and its link to the honey's composition, due to potential emerging contaminants such as Rare Earth Elements (REEs), should also be considered. This work offers a critical view on the use of honey as a natural superfood, in a direct relationship with its botanical and geographical origin.

Abstract
Background Ethiopia has a diverse set of floral and faunal resources that are used for primary health care in traditional or indigenous medicine. However, because they are passed down orally from one generation to the next, this indigenous medical practice is being ignored and is continuing to disappear. As a result, the goal of this ethnozoological study was to assess and document traditional healers' and indigenous people's knowledge in use of animal parts or products for medical purposes in the Diguna Fango District of Wolaita, Ethiopia. Materials and methods From March 2021 to June 2021, a field survey was conducted using personal interviews, semistructured questionnaires, and open group discussions utilizing a cross-sectional study approach. Totally, two hundred informants (125 men and 75 women) were provided information on the medicinal uses of various animals. Using a Microsoft Excel spreadsheet, the collected ethnozoological data were analyzed. The informant consensus factor, use value, and degree of fidelity were all determined. Results More than 50 different human ailments were treated using 39 different animal parts or products. Mammals had the highest use rate (N = 26, 66.67%). In the category of treating endocrine, metabolic, and nutritional diseases, Hystrix cristata had a high-fidelity level (FL = 95%). The highest use value (a maximum of 1.0) was for Bos taurus. The disease categories with the highest informant consensus factor (ICF) values were human immune deficiency disease, reproductive health, and genito-urinary ailment categories (ICF = 1.00). Wild animals (74%) outnumbered domestic animals (26%). The most common administration route (50%) was oral, and raw remedies had the highest use reports (58.9%). Conclusions The findings revealed that the study area contains a wealth of ethnozoological knowledge that could be useful in the formulation of novel drugs. The findings of the study should therefore be put to use in prospective ethnozoological, ethnopharmacological, and conservation-related studies in the region.

Abstract
Honey and propolis have recently become the key target of attention for treating certain diseases and promoting overall health and well-being. A high content of flavonoids and phenolic acids found in both honey and propolis contributes to the antioxidant properties to scavenge free radicals. Honey and propolis also exhibited antibacterial effects where they act in two ways, namely the production of hydrogen peroxide (H2O2) and gluconic acids following the enzymatic activities of glucose oxidase, which exerts oxidative damage on the bacteria. Additionally, the anti-inflammatory effects of honey and propolis are mainly by reducing proinflammatory factors such as interleukins and tumor necrosis factor alpha (TNF-α). Their effects on pain were discovered through modulation at a peripheral nociceptive neuron or binding to an opioid receptor in the higher center. The aforementioned properties of honey have been reported to possess potential therapeutic topical application on the exterior parts of the eyes, particularly in treating conjunctivitis, keratitis, blepharitis, and corneal injury. In contrast, most of the medicinal values of propolis are beneficial in the internal ocular area, such as the retina, optic nerve, and uvea. This review aims to update the current discoveries of honey and propolis in treating various ocular diseases, including their antioxidant, anti-inflammatory, antibacterial, and anti-nociceptive properties. In conclusion, research has shown that propolis and honey have considerable therapeutic promise for treating various eye illnesses, although the present study designs are primarily animal and in vitro studies. Therefore, there is an urgent need to translate this finding into a clinical setting.

Abstract
Since the ancient times, bee products (i.e., honey, propolis, pollen, bee venom, bee bread, and royal jelly) have been considered as natural remedies with therapeutic effects against a number of diseases. The therapeutic pleiotropy of bee products is due to their diverse composition and chemical properties, which is independent on the bee species. This has encouraged researchers to extensively study the therapeutic potentials of these products, especially honey. On the other hand, amid the unprecedented growth in nanotechnology research and applications, nanomaterials with various characteristics have been utilized to improve the therapeutic efficiency of these products. Towards keeping the bee products as natural and non-toxic therapeutics, the green synthesis of nanocarriers loaded with these products or their extracts has received a special attention. Alginate is a naturally produced biopolymer derived from brown algae, the desirable properties of which include biodegradability, biocompatibility, non-toxicity and non-immunogenicity. This review presents an overview of alginates, including their properties, nanoformulations, and pharmaceutical applications, placing a particular emphasis on their applications for the enhancement of the therapeutic effects of bee products. Despite the paucity of studies on fabrication of alginate-based nanomaterials loaded with bee products or their extracts, recent advances in the area of utilizing alginate-based nanomaterials and other types of materials to enhance the therapeutic potentials of bee products are summarized in this work. As the most widespread and well-studied bee products, honey and propolis have garnered a special interest; combining them with alginate-based nanomaterials has led to promising findings, especially for wound healing and skin tissue engineering. Furthermore, future directions are proposed and discussed to encourage researchers to develop alginate-based stingless bee product nanomedicines, and to help in selecting suitable methods for devising nanoformulations based on multi-criteria decision making models. Also, the commercialization prospects of nanocomposites based on alginates and bee products are discussed. In conclusion, preserving original characteristics of the bee products is a critical challenge in developing nano-carrier systems. Alginate-based nanomaterials are well suited for this task because they can be fabricated without the use of harsh conditions, such as shear force and freeze-drying, which are often used for other nano-carriers. Further, conjunction of alginates with natural polymers such as honey does not only combine the medicinal properties of alginates and honey, but it could also enhance the mechanical properties and cell adhesion capacity of alginates.

Abstract
There is an increase in the incidence of inflammatory eye diseases worldwide. Several dysregulated inflammatory pathways, including the NOD-like receptor protein 3 (NLRP3) inflammasome, have been reported to contribute significantly to the pathogenesis and progression of ophthalmic diseases. Although the available allopathic/conventional medicine has demonstrated effectiveness in managing eye diseases, there is an ongoing global demand for alternative therapeutics with minimal adverse drug reactions, easy availability, increase in patient-compliance, and better disease outcome. Therefore, several studies are investigating the utilization of natural products and herbal formulations in impeding inflammatory pathways, including the NLRP3 inflammasome, in order to prevent or manage eye diseases. In the present review, we highlight the recently reported inflammatory pathways with special emphasis on NLRP3 Inflammasomes involved in the development of eye diseases. Furthermore, we present a variety of natural products and phytochemicals that were reported to interfere with these pathways and their underlying mechanisms of action. These natural products represent potential therapeutic applications for the treatment of several inflammatory eye diseases.

Abstract
Honey, a concentrated natural product, is produced by honeybees (Apis mellifera) from the nectar of flowers. It contains over 200 compounds that exert various biological or pharmacological activities, ranging from antioxidant, anti-inflammatory, antimicrobial, and antihypertensive to hypoglycemic effects. Due to the presence of a plethora of bioactive compounds, as well as unique physicochemical properties, honey has been widely used as medicine throughout human history along with its extensive utilization as common food and flavoring agent. The application of neat honey for therapeutic purpose, however, poses some difficulties such as the maintenance of a required therapeutic concentration over an adequate timeframe due to the problem of liquefaction and leakage. This has driven researchers to incorporate honey into a range of formulations, for example, hydrogels, dressings, ointments, pastes, or lozenges. After a brief discussion of the chemistry and medicinal use of honey, this review focuses on commercial honey-based medicinal formulations as well as in vitro, in vivo, and clinical studies on noncommercial honey formulations for the treatment of various ailments. In addition to this, it also covers the application of honey formulations and the evidence underpinning their use.

Abstract
PURPOSE To evaluate the effects of manuka honey eye-drops in the treatment of meibomian gland dysfunction. METHODS This is an assessor-masked (single-blind), randomised controlled trial comparing conventional treatment group with interventional group using Optimel 16% manuka honey topical eye-drops. 59 patients were recruited to the study and randomised into two groups: one given regular lubricants and the other given Optimel 16% manuka honey eye-drops. The Standard Patient Evaluation of Eye Dryness (SPEED) score was measured at baseline and on follow-up. 4 patients were lost to follow-up. Multiple ocular surface parameters were graded from slit lamp examination by a masked assessor. Results were compared from baseline to follow-up date 3 weeks later. RESULTS Patients in the conventional treatment group demonstrated minimal difference in SPEED score at 3-week follow-up (mean difference 1.087, p=0.183), which was not statistically significant. However, measurements of tear film break-up time, corneal surface stain (Oxford), lid margin, conjunctival redness, as well as meibum quality and expressibility showed significant improvements at 3 weeks (p<0.01). Patients in the manuka honey eye-drops group showed significant difference after 3 weeks in SPEED score (mean difference 2.53, p=0.006), as well as in lid margin redness, conjunctival redness, corneal surface stain (Oxford), and meibum quality and expressibility (p=0.000). CONCLUSIONS Optimel 16% manuka honey eye-drops showed significant improvement in symptoms and objective signs in meibomian gland dysfunction and are an effective alternative treatment for meibomian gland dysfunction.

Abstract
In this study, the photodegradation of organophosphorus (OPs) pesticides in the honey medium was evaluated under sunlight irradiation. Some of the 22 samples collected at different sites contained OPs pesticides (Methyl parathion, Coumaphos and Fenitrothion) with an average of 8 ng/g. Moreover, three samples were found with pesticide residue levels exceeding the maximum residue limits (MRL ≥ 50 ng/g) imposed by the standard water (WHO). Gas chromatography (GC) combined with a tritium electron capture detector system was used for the analysis of OPs pesticides in honey. Total degradation of the Methyl parathion was obtained in less than 60 min of irradiation. Moreover, the elimination of the other OPs found in the samples was also effective with a rate of 85% for Coumaphos and Fenitrothion after 50 min of sunlight irradiation. The kinetics of the photodegradation reaction of all OPs pesticides studied followed a pseudo-first order model.

Abstract
Natural honey in spite of its usefulness is known to contain certain microorganisms. In the present study, we describe a case of Acanthamoeba keratitis after using topical honey administered by a traditional medicine therapist. A 32-year-old male came with red eye and blurred vision. The pain and other symptoms became more severe after the 1st week, with appearance of radial perineuritis at the cornea. A repeated interview revealed that 1 week before appearance of ocular symptoms, the patient had instilled a drop of natural honey in his left eye. Confocal microscopic cornea imaging demonstrated cyst and trophozoite of Acanthamoeba in the corneal stroma.

Abstract
AIM The aim of this study was to evaluate the efficacy of honey-based ophthalmic drop in patients with foreign body induced corneal ulcer. BACKGROUND Honey is traditionally used for skin, mucosal and corneal ulcers. Its use is well studied in human skin and mucosal ulcers and animal model of corneal ulcer with promising effects. METHODS In this randomized clinical trial, 50 patients with foreign body induced corneal ulcer were allocated to receive 70% sterile honey-based ophthalmic formulation or 0.3% ophthalmic ciprofloxacin, as the standard treatment every 6 hours. All the patients were examined for the size of corneal epithelial defect, corneal infiltration and depth and followed on a daily basis until complete healing. Duration for complete healing was considered as the outcome measure. Smear, culture, antibiogram and minimum inhibition concentration (MIC) tests were performed for honey and ciprofloxacin in all patients. RESULTS The average durations of complete healing of corneal epithelial defect in the honey and ciprofloxacin groups were 3.88 ± 3.44 vs. 6.32 ± 3.69days, respectively (p=0.020). No significant difference was observed between two groups regarding an average duration of healing of corneal infiltration (8.12 ±1.94 days vs. 8.64±2.15 days, p=0.375). MIC of honey for pseudomonas aeruginosa was 60%w/w, for E.Coli 40% w/w, and for staphylococcus aureus 30% w/w. CONCLUSION Honey based ophthalmic drop can acceleratethe corneal epithelial defect healing in patients with foreign body induced corneal ulcer, compared to ophthalmic ciprofloxacin as a standard treatment. The study was registered in Iranian registry of clinical trial center (IRCT) with registration number IRCT2015020120892N1.

Abstract
This study evaluated the effects of Gelam honey (GH) on ex vivo corneal fibroblast ulcer model via wound healing assay, gene expression and immunocytochemistry. Corneal fibroblasts from New Zealand white rabbits were culture expanded. The corneal fibroblast wound healing capacity was observed by creating a circular wound onto confluent monolayer cells cultured in basal medium (BM), BM with GH, serum-enriched basal medium (BMS) and BMS with GH respectively. Wound healing assay and phenotypic characterization of the corneal fibroblast were performed at different stages of wound closure. Expression of aldehyde dehydrogenase (ALDH), vimentin, α-smooth muscle actin (α-SMA), lumican, collagen I and matrix metalloproteinase 12 (MMP 12) were measured at day 1, day 3 and complete wound closure day. Corneal fibroblast cultured in BMS with GH demonstrated the fastest wound closure, at day 5 post wounding. The gene expressions of ALDH and vimentin were higher than control groups while α-SMA expression was lower, in GH enriched media. The expressions of lumican, collagen I and MMP 12 were also higher in cells cultured in GH enriched media compared to the control groups. GH was shown to promote in vitro corneal fibroblast wound healing and may be a potential natural adjunct in the treatment of corneal wound.

Abstract
Dry eye disease (DED) is one of the most frequent presentations to optometrists with over 16 million US adults (6.8% of adult population) diagnosed as having this disorder. The majority of associated marketed products offer relief from symptomatology but do not address aetiology. DED harbours many distinguishing features of a chronic inflammatory disorder. The recent explosion in human microbiome research has sparked interest in the ocular microbiome and its role in the preservation and extension of ocular surface health and in the contribution of the gut microbiome to chronic systemic inflammation and associated "Western life-style" diseases. With a significant lack of success for many patients using currently available DED treatments, in this era of the microbiome, we are interested in exploring potential novel therapies that aim to reconstitute healthy bacterial communities both locally and distally (in the gut) as a treatment for DED. Although this direction of investigation is in its infancy, burgeoning interest makes such a review timely. This paper considers a number of studies into the use functional foods and associated products to ameliorate dry eye.

Abstract
Introduction Pseudomonas aeruginosa is a common cause of microbial keratitis that can cause a significant loss of visual acuity. Antibiotics, including fluoroquinolones and aminoglycosides, are clinically effective against Pseudomonas-induced keratitis, but their effectiveness has been conspicuously reduced as resistant pathogens have become more potent. This study sought to evaluate the clinical and antibacterial effects of tualang honey as an alternative therapeutic agent against Pseudomonas-induced keratitis. Methods We conducted a randomized control trial in which 30 rabbits were injected intrastromally with 1,000 colony-forming units (CFU) of Pseudomonas aeruginosa in the right eye of each rabbit (n = 30). The rabbits were then randomized into three groups of 10 rabbits each. Group A was treated with topical gentamicin 0.3%, group B was treated with topical tualang honey 30%, and group C received both treatments. The specified treatments were administered every two hours from 24 to 48 hours post injection, and subsequently every four hours for six days. Clinical examinations were performed on days one, two, three, five, and seven, and the mean results of slit lamp examinations (SLEs) were documented. On day seven after pseudomonas induction, the rabbits were euthanized and their corneas were harvested to determine the median CFU per cornea. Results There were no statistically significant differences (p > 0.05) in mean SLE scores (p = 0.209) or median CFU values (p = 0.820) between the three groups. Conclusion Topical gentamicin, topical tualang honey, and the combination of the two all showed similar clinical and antimicrobial effects in treating Pseudomonas-induced keratitis in rabbits. These findings should be verified in further studies with larger sample sizes and the addition of a control group.

Abstract
Honeydew honey has differentiated chemical and physicochemical characteristics besides potential functional properties such as antimicrobial, anti-inflammatory and antioxidant. In this sense, the interest and consumption of this honey as a functional product by the food industry and consumers have increased. Honeydew honeys usually present dark color, a lower content of monosaccharides and higher values of pH, acidity, electric conductivity, proteins, minerals, phenolic compounds, and oligosaccharides compared to blossom honeys, which contribute to its outstanding biological activities. Consequently, contaminations and adulterations of this honey can occur and compromise the quality, safety and authenticity of honeydew honey. Thus, detailed knowledge of the composition and properties of honeydew honeys is of great importance, especially considering that honeydew honeys are still few studied and therefore underestimated. Therefore, in this review, the physicochemical characteristics, chemical and bioactive composition, functional and health-promoting properties of honeydew honey as well as contamination, adulteration and authenticity of this honey are summarized.

Abstract
Both honeybees (Apis spp.) and stingless bees (Trigona spp.) produce honeys with high nutritional and therapeutics value. Until recently, the information regarding potential health benefits of stingless bee honey (SBH) in medical databases is still scarce as compared to the common European bee honey (EBH) which is well known for their properties as therapeutic agents. Although there have been very few reports on SBH, empirically these products would have similar therapeutic quality as the EBH. In addition, due to the structure of the nest, few studies reported that the antimicrobial activity of SBH is a little bit stronger than EBH. Therefore, the composition of both the types of honey as well as the traditional uses and clinical applications were compared. The results of various studies on EBH and SBH from tissue culture research to randomised control clinical trials were collated in this review. Interestingly, there are many therapeutic properties that are unique to SBH. Therefore, SBH has a great potential to be developed for modern medicinal uses.

Abstract
Honeydew honey is increasingly valued due to its pronounced antibacterial potential; however, the underlying mechanism and compounds responsible for the strong antibacterial activity of honeydew honey are still unknown. The aim of this study was to investigate the inhibition of bacterial growth of 23 honeydew honey samples. Activity of bee-derived glucose oxidase (GOX) enzyme, the content of defensin-1 (Def-1) and hydrogen peroxide (H2O2), and total polyphenol content were determined in the 23 honey samples. Our results demonstrated that antibacterial activity of honeydew honey was equivalent to medical-grade manuka and kanuka honey and was abolished by catalase. Although H2O2 is an important factor in the inhibition of bacterial growth, polyphenolic compounds and their interaction with H2O2 are the key factors responsible for high antibacterial activity of honeydew honey. In addition, our results indicated that the antibacterial activity of honeydew honey is not dependent on GOX-mediated production of H2O2 or the presence of Def-1.

Abstract
Background This study investigates and compares the effect of phenytoin and honey cream on intensity of pain and episiotomy wound healing in nulliparous women. Methods This research was conducted by double-blinded randomized clinical trial method on 120 nulliparous women in three groups of phenytoin, honey and placebo. After delivery and episiotomy, mothers used a knuckle of the prescribed creams on their episiotomy area, every night until 10-night. Evaluation of wound healing using REEDA scale and pain intensity with numerical rating scale of pain took place within the first 24 h and after 7 and 14 days of delivery. Results Results showed significant differences between healing scores of the three groups for the seventh day after delivery. Healing score in the honey group was lower than that in placebo group. On the fourteenth day after delivery, the healing scores showed no significant differences between the three groups. Measuring pain intensity did not show any significant difference in the three groups after 7 and 14 days of delivery. Conclusions Both honey and phenytoin led to episiotomy wound healing; however, honey caused the wound healing better than the phenytoin. Honey and phenytoin did not reduce episiotomy pain.

Abstract
GC/MS of headspace solid phase micro extraction (HS-SPME) and solvent extractives along with targeted HPLC-DAD of Polish fir (Abies alba Mill.) honeydew honey (FHH), were used to determine the chemical profiles and potential markers of botanical origin. Additionally, typical physical-chemical parameters were also assigned. The values determined for FHH were: conductivity (1.2 mS/cm), water content (16.7 g/100 g), pH (4.5), and CIE chromaticity coordinates (L* = 48.4, a* = 20.6, b* = 69.7, C* = 72.9, and h° = 73.5). FHH contained moderate-high total phenolic content (533.2 mg GAE/kg) and antioxidant activity (1.1 mmol TEAC/kg) and (3.2 mmol Fe2+ /kg) in DPPH and FRAP assays. The chemical profiles were dominated by source plant-originated benzene derivatives: 3,4-dihydroxybenzoic acid (up to 8.7 mg/kg, HPLC/honey solution), methyl syringate (up to 14.5%, GC/solvent extracts) or benzaldehyde (up to 43.7%, GC/headspace). Other markers were terpenes including norisoprenoid (4-hydroxy-3,5,6-trimethyl-4-(3-oxobut-1-enyl)cyclohex-2-en-1-one, up to 20.3%, GC/solvent extracts) and monoterpenes, mainly linalool derivatives (up to 49%, GC/headspace) as well as borneol (up to 5.9%, GC/headspace). The application of various techniques allowed comprehensive characterisation of FHH. 4-Hydroxy-3,5,6-trimethyl-4-(3-oxobut-1-enyl)cyclohex-2-en-1-one, coniferyl alcohol, borneol, and benzaldehyde were first time proposed for FHH screening. Protocatechuic acid may be a potential marker of FFH regardless of the geographical origin.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This review provides information on the antimicrobial research which has taken place on South African natural products for the last eight years (2009-2016). This important field is the backbone of all studies involving the use of medicinal plants against infectious diseases and hence can form the mainstay for future studies. MATERIALS AND METHODS All publications within the years 2009-2016 were considered. Exclusion criteria were studies not involving South African medicinal natural products and those publications where full articles could not be accessed. An overview of the most common experimental methods used and new advances in terms of antimicrobial investigations are provided. Disease categories selected for further investigation were skin and wounds, respiratory, gastrointestinal, sexually transmitted and ophthalmic infections amongst others. Alternate natural products and combinations studies were also included. RESULTS The minimum inhibitory concentration (MIC) was the most commonly used experimental method to determine antimicrobial activity. Staphylococcus aureus was the most commonly tested skin pathogen and Klebsiella pneumoniae was the most common pathogen implicated in respiratory disorders. Only 20% of gastrointestinal studies included commonly implicated pathogens such as Shigella flexneri and Campylobacter species. CONCLUSION Multidisciplinary studies have emerged as a strong support for antimicrobial investigations and show the importance of including toxicity when studying antimicrobial efficacy. Alternate approaches (for example biofilms and quorum sensing) at examining antimicrobial effects are encouraged. Studies on resistant strains require more insight and future recommendations should look at consistent dosing and investigations on compound interactions amongst others.

Abstract
BACKGROUND The aim was to evaluate the efficacy of standardised Manuka (Leptospermum species) antibacterial honey as adjunctive twice daily treatment to conventional therapy (warm compresses, lid massage and preservative-free lubricant), in participants with evaporative dry eye due to moderate to advanced meibomian gland dysfunction. METHODS This prospective, open-label study involved 114 participants. After two weeks of conventional therapy participants were randomised to one of three treatment groups: Optimel Antibacterial Manuka Eye Gel (98 per cent Leptospermum species honey) plus conventional therapy (n = 37), Optimel Manuka plus Lubricant Eye Drops (16 per cent Leptospermum species honey) plus conventional therapy (n = 37) and a control (conventional therapy) (n = 40). Clinical evaluations performed at baseline and Week 8 included: symptom scores (Ocular Surface Disease Index, Ocular Comfort Index), daily lubricant use, tear assessments (break-up time, secretion, osmolarity and InflammaDry), corneal sensation, ocular surface staining, meibomian gland secretion quality and expressibility, bulbar conjunctival, limbal and lid marginal redness and eyelid marginal bacterial cultures and colony counts. RESULTS Significant improvements (p ≤ 0.05) occurred at Week 8 in symptoms, tear break-up time, staining, tear osmolarity, meibum quality and bulbar, limbal and lid margin redness for all treatments. Improvement in staining was significantly greater with Optimel 16 per cent drops (p = 0.035). Significant improvements (p < 0.05) in meibomian gland expressibility and InflammaDry occurred for both Optimel treatments. Optimel 98 per cent gel was significantly more effective in improving meibum quality (p = 0.005) and gland expressibility (p = 0.042). Total eyelid marginal bacterial colony counts reduced significantly with Optimel 16 per cent drops (p = 0.03) but not the other treatments. Staphylococcus epidermidis counts reduced significantly with Optimel 16 per cent drops (p = 0.041) and Optimel 98 per cent gel (p = 0.027). Both Optimel treatments significantly reduced the need for lubricants, with Optimel 16 per cent drops decreasing lubricant use most (p = 0.001). Temporary redness and stinging were the only adverse effects of Optimel use. CONCLUSIONS Optimel antibacterial honey treatments are effective as adjunctive therapies for meibomian gland dysfunction.

Abstract
Purpose In eye care field, contact lenses (CL) have a great impact on improving vision, but their use can be limited by ocular infection. CL- associated infections can be reduced by good attention to CL storage case practice. CL-care solutions should be able to control microbial growth on CL. The aim of the study was to evaluate and compare the efficacy of CL-care solutions (found in Egyptian market) with some natural compounds in removal and inhibition of bacterial biofilm formed on soft CL. Clinical isolates were recovered from patients having conjunctivitis from Benha University Hospital and identified microbiologically. Quantification of biofilm was done using microtiter plate assay. Three multipurpose CL-care solutions were examined for their ability to remove and inhibit biofilm. Also four natural extracts having antibacterial activity and are safe on eye were tested for their anti-biofilm activity. Results The major bacterial isolates from eye infections were Pseudomonas aeruginosa (36%) and Staphylococcus spp. (37.8%). Only 33.3% of isolates showed ability to produce weak to moderate biofilm. The tested multi-purpose CL-care solutions showed moderate ability to remove preformed biofilm. Among the tested natural compounds, Calendula officinalis and Buddleja salviifolia extracts showed an excellent efficacy in inhibition of biofilm and also removal of preformed biofilm. Conclusion This study demonstrated that isolates from infected eye and CL-cases showed weak to moderate biofilm formation. Calendula officinalis and Buddleja salviifolia extracts showed excellent effect on inhibition and removal of biofilm, these extracts could be added into CL-care solutions which could markedly reduce eye-infections during CL-wear.

Abstract
Infection is a major cause of morbidity and mortality at all stages of chronic kidney disease (CKD). Multiresistant organisms are becoming increasingly common, particularly in the CKD population. Unfortunately, the rapid evolution of antibiotic resistance has not been mirrored by innovation in new antibiotic agents. Novel treatments are therefore urgently needed. Honey has garnered much interest due to its broad-spectrum antibacterial properties based on extensive experimental data. Unlike conventional antibiotics, honey has an added advantage as it appears to avoid inducing antimicrobial resistance in bacteria. This review discusses the potential mechanisms of action and role of honey in infection management in the general population, epidemiology and special challenges of infections in CKD populations, and the clinical trial evidence pertaining to the safety and efficacy of honey for the prevention and treatment of infections in CKD population.

Abstract
Honey has been widely accepted as food and medicine by all generations, traditions, and civilizations, both ancient and modern. For at least 2700 years, honey has been used by humans to treat a variety of ailments through topical application, but only recently have the antiseptic and antimicrobial properties of honey been discovered. Honey has been reported to be effective in a number of human pathologies. Clinical studies have demonstrated that application of honey to severely infected cutaneous wounds rapidly clears infection from the wound and improves tissue healing. A large number of in vitro and limited clinical studies have confirmed the broad-spectrum antimicrobial (antibacterial, antifungal, antiviral, and antimycobacterial) properties of honey, which may be attributed to the acidity (low pH), osmotic effect, high sugar concentration, presence of bacteriostatic and bactericidal factors (hydrogen peroxide, antioxidants, lysozyme, polyphenols, phenolic acids, flavonoids, methylglyoxal, and bee peptides), and increase in cytokine release, and to immune modulating and anti-inflammatory properties of honey; the antimicrobial action involves several mechanisms. Despite a large amount of data confirming the antimicrobial activity of honey, there are no studies that support the systemic use of honey as an antibacterial agent.

Abstract
BACKGROUND Honey is used as a traditional medicine for centuries by different cultures for the treatment of various disorders. However, not all honeys exhibit equal antimicrobial potency and only a few meet the criteria for clinical usage. AIM The aim of the study was to determine clinical efficacy of sterilised honeydew honey in the treatment of the lower leg ulcers in 25 patients. Furthermore, we evaluated honey acceptability of patients in terms of pain and overall satisfaction. METHODOLOGY A total of 25 patients with chronic venous leg ulcers were recruited into this study. The 100% γ-irradiated sterile honeydew honey was applied onto the cleaned wounds and each wound was assessed at the least two times in for a period of 6 weeks. RESULTS During the course of treatment, the average wound area of all patients decreased significantly from 51 (3-150) to 22 (0-91) cm(2). Eighteen patients (72%) experienced a decrease in reported pain levels while five patients (20%) experienced the same level of pain throughout the study. The overall satisfaction with honey treatment was positive in 80% of patients. Only two patients experienced poor tolerance due to problems at ulcer site related to pain. CONCLUSION Based on these findings, honeydew honey has the potential to be one of the medical-grade honeys.

Abstract
Purpose. This trial was designed to evaluate the efficacy and safety of topical honey eye drops in patients with diagnosed VKC.
Methods. This clinical trial was conducted on 60 patients with diagnosed VKC. The patients were selected and randomly allocated between two groups of 30. Patients in two groups received honey eye drop (60% in artificial tear) or placebo, other than cromolyn and fluorometholone 1% eye drops, to be used topically in each eye, four times per day. The patients were examined with slit lamp and torch at baseline and the follow-up visits on the 1st, 3rd, and 6th months of the study for redness, limbal papillae, and intraocular pressure.
Results. Out of 60 patients who completed the study, 19 patients (31.7%) were female. There was significant increase in eye pressure and reduction in redness as well as limbal papillae, following the consumption of the honey drop in honey group compared to placebo control group (P < 0.05). At the end of trial, one patient in honey group and 7 ones in placebo group had limbal papillae (P < 0.05). Conclusion. Topical honey eye drops, when used along with Cromolyn and Fluorometholone eye drops, might be beneficial for the treatment of VKC.

Abstract
The global prevalence of chronic diseases such as diabetes mellitus, hypertension, atherosclerosis, cancer and Alzheimer's disease is on the rise. These diseases, which constitute the major causes of death globally, are associated with oxidative stress. Oxidative stress is defined as an "imbalance between oxidants and antioxidants in favor of the oxidants, potentially leading to damage". Individuals with chronic diseases are more susceptible to oxidative stress and damage because they have elevated levels of oxidants and/or reduced antioxidants. This, therefore, necessitates supplementation with antioxidants so as to delay, prevent or remove oxidative damage. Honey is a natural substance with many medicinal effects such as antibacterial, hepatoprotective, hypoglycemic, reproductive, antihypertensive and antioxidant effects. This review presents findings that indicate honey may ameliorate oxidative stress in the gastrointestinal tract (GIT), liver, pancreas, kidney, reproductive organs and plasma/serum. Besides, the review highlights data that demonstrate the synergistic antioxidant effect of honey and antidiabetic drugs in the pancreas, kidney and serum of diabetic rats. These data suggest that honey, administered alone or in combination with conventional therapy, might be a novel antioxidant in the management of chronic diseases commonly associated with oxidative stress. In view of the fact that the majority of these data emanate from animal studies, there is an urgent need to investigate this antioxidant effect of honey in human subjects with chronic or degenerative diseases.

Abstract
Perianal fistula is a common disease that affects particular patients with inflammatory bowel disease. Honey has been used as a natural remedy for centuries for the treatment of various disorders. We report a patient with persistent fistulas, in whom conventional medical and surgical therapy failed. In this case, most of fistulas in gluteofemoral region were completely healed and closed after 6 months of treatment with honey. In addition, honey reduced inflammation, pain and induration of affected region. This medical approach positively affected patient's mental condition and also improved his quality of life.
