In order to investigate the effect of in ovo injection of different levels of royal jelly on the hatchability rate and the quality of one-day-old broiler chickens (Ross 308) and some traits of the immune system, we have conducted an experiment using 640 eggs in a completely randomized design with four levels of royal jelly injection including 1) 1 mL of physiological serum (control), 2...

Objectives: Royal jelly (RJ), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. Important component of royal jelly are proteins which form about 50% of the dry mass of RJ. Major royal jelly proteins (MRJPs) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...

Royal jelly has been demonstrated to have several physiological activities. However, in the literature, different reactions induced by royal jelly are reported. We describe a case of seven-year-old child that was referred to our observation for two episodes of oral allergy syndrome (OAS) that appeared ten minutes after ingestion of royal jelly. Skin prick test with standard panel of inhalant an...

the aim of this study was to compare the effects of using different levels of royal jelly in semen extender on viatal characteristics of goat sperm after freezing. semen was collected from four adult bucks twice a week and samples pooled together. sperm samples (six repeats) containing royal jelly in four levels (0.5, 1, 1.5 and 2%) had been frozen. after semen samples freezing – were thawed an...

Royal jelly is known as a functional food containing many useful minerals. In this study, we found an anti-environmental estrogen activity of royal jelly. Bisphenol A (BPA) is an environmental estrogen that stimulates proliferation of human breast cancer MCF-7 cells. Royal jelly inhibited the growth-promoting effect of BPA on MCF-7 cells, even though it did not affect the proliferation of cells...

background: bleomycin (bl) is a glycopeptide antibiotic obtained from the bacterium streptomyces verticillus which is routinely used for treatment of human cancers. royal jelly (rj) is a production from the hypo pharyngeal, mandibular and post cerebral glands of nurse bees. rj consists of 66% water, 15% sugars, 5% lipids, and 13% proteins, essential amino acids and vitamins. objective: the aim ...

background royal jelly (rj), a food item secreted by worker honeybees, is a mixture that contains protein, glucose, lipid, vitamins, and minerals; it is widely used as a commercial medical product. previous studies have shown that rj has a number of physiological effects, such as anti-inflammatory, antitumor, antiallergic and antioxidant activities. objectives in the present study, the anti-inf...

conclusions it seems that rj does not appear to have significant immediate effects on glycemic factors in patients with type 2 diabetes. however, further studies with larger sample sizes and different doses of rj are needed to achieve more precise results. background type 2 diabetes is the fourth major public health problem worldwide. royal jelly (rj) insulin-like activity and blood glucose mod...

The purpose of this study was to investigate the effects of royal jelly against radiation-induced oral mucositis in rats. This study was comprised of 48 adult male Sprague-Dawley rats, each between eight and 12 weeks old and weighing 275±35 g. These were divided randomly into six groups; Group C (control), Group IR (irradiation), Group IR+RJ50 (irradiation plus 50 mg/kg royal jelly), Group IR+R...
