Aim: Royal jelly is a bee product that secreted from glands of young worker bees and used resource of food for larvae and queen honeybee. Royal jelly which is very important for physiological development of queen honeybee and larvae, also used by people due to the nutritional properties and positive effects on health. Royal jelly contains water, lipid, protein, carbohydrate, amino acid, short peptide, vitamin, phenolic compounds, trace element and minerals. It was suggested that composition of royal jelly varies depending on the geographical structure of the zone, climate, flora that it is produced, storage condition and bees race. There are also publications which suggest that mineral content of royal jelly is independent of geographical structure and climate, but only varies depending on the harvesting time. There are not so many study related with chemical composition and biological properties of royal jelly that is produced in Turkey. In this study, it was aimed to determine some element levels in royal jelly samples that obtained from Bursa province, Mustafakemalpaşa district. Material and Methods: Element levels of copper (Cu), zinc (Zn), magnesium (Mg) and calcium (Ca) determined by Atomic Absorption Spectrophotometer (AAS) (n=3). For each element, the results were exhibited as mean±standard deviation. Results: The amount of Cu was determined 3.25±0.05 mg/kg, the amount of Zn was 23.87±1.33 mg/kg, the amount of Mg was 794.33±38.44 mg/kg and the amount of Ca was 250.87±24.49 mg/kg in Bursa royal jelly. Conclusion: Element levels of Bursa royal jelly are at a level that can contribute to daily mineral requirement. However, there is a need for further in vivo studies on the availability of mineral additives and their therapeutic utility.

Objective: Peroxisome proliferator-activated receptor gamma (PPARγ), lipids, lipoproteins, and adipokines have recently been shown to be associated with psychiatric diseases. Our major aim is to investigate the contribution of the PPARγ gene polymorphism, adipokines, lipids, and lipoproteins to the development of major depression. Material and Methods: The frequency of Pro12Ala in exon 2 and C478T in exon 6 of the PPARγ gene, lipids and adipokines in major depression (n = 78) and control subjects (n= 64) were analyzed. Genotypes of PPARy gene polymorphisms were examined. Serum leptin, adiponectin, and resistin were studied by enzyme-linked immunosorbent assay (ELISA). Serum apo A1, apo B, and Lp(a) levels were determined by immunonephelometry. Serum total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol levels were analyzed by enzymatic methods. Results: The genotypes of exon 2 and exon 6 distribution did not differ between the control subjects and patients with major depression. Frequencies of genotypes of Pro12Ala, and Ala12Ala in exon 2 in overweight and obese patients with major depression were higher than those of overweight and obese controls. C478T polymorphism was highest in overweight and obese patients with major depression. Pro12Ala and Ala12Ala genotypes in exon 2 of PPARγ gene in patients were found to be associated with triglyceride and HDL-cholesterol. There were significant differences regarding glucose, total cholesterol, LDL-cholesterol, apo B, Lp(a), adiponectin and resistin levels between patient and control subjects. Conclusion: PPARγ exon gene polymorphisms, alterations in lipid profile and adipokines may be associated with the development of major depression.
