background: royal jelly has been shown to have antioxidant and antidiabetic effects. the objective of this study was to evaluate the protective effect of rj against kidney damage in streptozotocin induced diabetic rats. methods: thirty two male wistar rats were divided randomly into four groups (n=8 per group). normal control and diabetic control groups received 1cc/day distilled water, normal ...

Royal jelly (RJ) intake lowers serum cholesterol levels in animals and humans, but the active component in RJ that lowers serum cholesterol level and its molecular mechanism are unclear. In this study, we set out to identify the bile acid-binding protein contained in RJ, because dietary bile acid-binding proteins including soybean protein and its peptide are effective in ameliorating hyperchole...

In an intriguing article titled “Horticulture: the Font for the Baptism of Genetics” by Robert C. Olby (2000) suggests that the establishment of genetics as an experimental science should be credited to the Evolution Committee of the Royal Horticultural Society (RHS). William Bateson was a member of this committee and he was the stimulus for the adoption of Mendelism as a science and for the ac...

This paper presents a study on the transfer and metabolism of triadimefon residues from rape flowers to apicultural products. In the field trials, honeybee colonies were placed in four rape greenhouses treated with triadimefon on standard dosage. Apicultural products (pollen, honey, and royal jelly) were collected on a regular basis. Sample preparation and extraction procedure were established....

This article proposes guidelines for quality standards of royal jelly. The proposals are based on two sets of data; the first from our study of the factors that may affect the royal jelly's chemical composition (protein and sugar supplementation of beehives) and the second on the analysis of a great number of samples from across Greece to establish natural variability of this product. We compar...

BACKGROUND Royal jelly is a widely ingested supplement for health, but its effects on humans are not well known. The objective was to evaluate the effects of long-term royal jelly ingestion on humans. METHODS We conducted a randomized placebo-controlled, double-blind trial. A total of 61 healthy volunteers aged 42-83 years were enrolled and were randomly divided into a royal jelly group (n = ...

The study was designed to investigate the efficacy of treating the adult male rats with royal jelly (1g/kg B. Wt. orally) for one month with or without hydrogen peroxide (0.5%) in drinking water on sexual efficiency, glutathione and malondialdehyde tissue testis levels. The current study demonstrated that male rats receiving hydrogen peroxide caused a significant decrease (P<0.05) in the sperm ...
