Abstract
Chemical elements of Gelée Royale (R J) are reported to be somewhat different depending on the analizer but it is said to contain Vitamin B1, B2, B5, B6, B8, B12, Pantothenic acid, Biotin, Amino acids, Mono-Saccharide, Polysaccharide, Enzyme, Acetylcholine, Cholinesterase, Biopterine, Kynurenine, Antibacterial and Antitumor substances etc.
In the present study, fertilized eggs received the injection of R J and an investigation was made on the influence of this injection on the development of chick embryos as well as on the nitrogen metabolism in the allantoic fluid of the developing eggs.
Generally speaking, embryos of the eggs received R J injection showed better growth with larger increase in the body weight than the control eggs in the latter stage of incubation. In all cases, no deformity was recognized. X-ray findings of the bone showed no abnormality. In the latter stage of incubation, the nitrogen content of allantoic fluid was slightly higher in the eggs received R J than that of the control demonstrating the change in the dose of nitrogen excretion.
