Diabetes Mellitus (DM) is considered a very common health problem today. It causes many acute and chronic complications and negatively affects the quality of life of patients. It is known that diabetes has an impact on many biochemical processes. This study aimed to evaluate the interaction between royal jelly (RJ) and diabetes with irisin, a parameter that has not been investigated before. The study was planned with 3 groups: control group, DM group, DM+350 mg/kg RJ group. In the experiments, 18 female Wistar albino rats were studied. Irisin levels in rat blood serum were determined using the ELISA (Enzyme-Linked Immuno Sorbent Assay) method. Glucose levels in blood taken from the tail vein were determined with a glucometer. As a result of the experimental study, a statistically significant difference was found in the DM+350 mg/kg RJ group compared to the control group (p
Purpose: Cadmium (Cd) is a toxic metal that seriously threatens human health due to environmental pollution, is widely used in industry and agriculture, and causes oxidative stress and tissue damage. This study aims to examine the effect of royal jelly (RJ) on oxidative status and telomerase enzyme activity in tissue damage induced by Cd.
Materials and Methods: The experimental design was made with 6 rats in each group. A total of 6 groups were created: control group, Cd group, 250 mg/kg RJ group, Cd + 250 mg/kg RJ group, 400 mg/kg RJ group, Cd + 400 mg/kg RJ group. In the study, total oxidant status and total antioxidant status in blood serum were investigated by colorimetric method, and telomerase enzyme activity in ovarian tissue was investigated by ELISA method.
Results: Cd caused an increase in oxidative capacity (23.80 ± 2.4) and a significant decrease was determined after RJ applications compared to the control group. After RJ application, the best total antioxidant response was observed in the 250 mg/kg RJ and Cd + 250 mg/kg RJ groups. Cd significantly reduced telomerase enzyme activity (0.90 ± 0.13). RJ administered for treatment after Cd application increased telomerase levels up to the control level (1.40 ± 0.05). The best treatment response was observed in the Cd + 250 mg/kg RJ group (1.42 ± 0.05).
Conclusion: Cd causes oxidative stress and that RJ may have curative effects by increasing the antioxidant capacity and telomerase enzyme activity RJ is a promising natural product and can contribute to recovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
