Rats received their doses orally for 28 days. Results revealed that curcumin possesses high antioxidant activity, as demonstrated by its DPPH, ABTS+ scavenging activity, and FRAP chelating capacity. The administration of EMB-LD or EMB-HD elevated lipid peroxidation and protein oxidation and significantly decreased enzymatic and non-enzymatic antioxidants. Liver enzyme activities and lipid and protein contents in rat serum were markedly altered after EMB treatment. Additionally, pro-inflammatory and apoptosis-related genes, and tissue structure were significantly altered in rats that received EMB. However, rats receiving Cur only enhanced the antioxidant status and reduced oxidation biomarkers. Further, rats that received curcumin and then were intoxicated with EMB exhibited significant modulation in most measured parameters compared with their respective treated groups.

Furthermore, the impact of delivering bee venom and melittin via PLGA nanoparticles on reducing their toxic effects was investigated. Fifty male mice were divided randomly into five equal groups and were injected intra-peritoneally for 3 weeks as follows: control (saline), bee venom (15μg/kg), melittin (500μg/kg), bee venom loaded PLGA NPs (15μg/kg), PEG targeted melittin-encapsulated PLGA-NPs (250 μg/kg).
