In recent years, the consideration of natural products as anti-inflammatory and antioxidative treatments has more interested worldwide. Moreover, natural products are easily obtained and are relatively safe the Royal jelly (RJ) is one of them. The current study was carried to evaluate the effects of pregabalin (PGB) on physiological activity of sperms, reproductive hormones assay and some biochemical analysis. Forty (40) male albino rats (10-weeks-old) were divided into four groups (10 rats each): G1 (treated with PGB drug, 150 mg/kg B.wt (Lyrica-Pfizer-Pharmaceutical Industries), G2 (treated with RJ 1g/kg), G3 (treated with PGB drug and RJ together), and G4 control treated with normal saline only. all groups were treated orally via stomach tube for 60 consecutive days.. PGB caused a significant reduction in sperm count, sperm viability, motility and sperm abnormality percent, serum FSH, LH and testosterone levels, the co-administration of RJ caused normal level of the previous tests near the control group level. Results of the lipid profile and some the present results of the liver function parameters showed increased concentrations in PGB-treated group, but after treated with RJ the levels were recovered to normal level. In the studied antioxidants markers, the results appeared high level in malondialdehyde (MDA) and low level in the antioxidants enzymes; superoxide dismutase (SOD) and catalase (CAT) the RJ was appeared direct effect on MDA and showed decreased concentration of MDA and increased levels in the studied antioxidants enzymes of the PGB group which treated with RJ.
The gas sensing properties of Co3O4and Co3O4:Y nano structures were investigated. The films were synthesized using the hydrothermal method on a seeded layer. The XRD, SEM analysis and gas sensing properties were investigated for Co3O4and Co3O4:Y thin films. XRD analysis shows that all films are polycrystalline in nature, having a cubic structure, and the crystallite size is (11.7)nm for cobalt oxide and (9.3)nm for the Co3O4:10%Y. The SEM analysis of thin films obviously indicates that Co3O4possesses a nanosphere-like structure and a flower-like structure for Co3O4:Y.The sensitivity, response time and recovery time to a H2S reducing gas were tested at different operating
