Background
Frequent consumption of fructose and saturated fatty acids increase risk of metabolic syndrome (MS). Features of MS include insulin resistance, dyslipidemia, visceral obesity, and hypertension. The aim of this study was to investigate the role of omega‐3 and l‐carnitine in ameliorating features of MS.
Methods
MS was induced in rats by high‐fructose high‐fat fed diet for 8 weeks. They were randomly divided into five groups: normal control, MS control group treated with saline, MS groups given omega‐3 (260 mg/kg), l‐carnitine (200 mg/kg), or metformin (100 mg/kg) daily for 4 weeks. Body weight, relative organ weight, glucose, insulin, adiponectin, and lipid profiles were estimated. Also glucose transporter 4 (GLUT4) content and peroxisome proliferator‐activated receptor‐gamma (PPARγ) protein expressions were determined.
Results
Omega‐3 and l‐carnitine caused decrease in both MS‐induced increase in body weight and glucose similar to metformin. They reduced insulin level and resistance with increased adiponectin, and correction of MS‐induced hyperlipidemia. Drugs also increased GLUT4 and PPARγ protein expression compared with MS control group.
Conclusion
Omega‐3 and l‐carnitine improve features of MS via increased GLUT4 and PPARγ expression.
Increased fructose intake has been linked to the epidemiology of insulin resistance, type 2 diabetes mellitus, renal damage, and metabolic syndrome (MS). As oxidative stress plays a pivotal role in the pathology of insulin resistance, the present study was conducted to investigate the effects of Nigella Sativa (NS) and ginger as potent antioxidants on fructose-induced MS in rats. Male rats were fed with a high‐fructose high-fat-fed diet for 8 weeks. By the end of the 8th week, rats were divided into four groups; one was left untreated (normal control) and MS control group was treated with saline. MS groups were given Nigella sativa (4 ml/kg) and ginger (500 mg/kg) daily for 4 weeks. Markers chosen for assessment included the effect on body weight gain, glucose, insulin, adiponectin levels, and lipid profile. Also, protein expressions were estimated by glucose transporter 4 (GLUT4) content and peroxisome proliferator‐activated receptor‐gamma (PPARγ). Nigella sativa and ginger ameliorated some manifestations of MS, including an increase in body weight, glucose, insulin level, and resistance. Besides, both drugs lowered insulin resistance, induced hyperlipidemia and increased adiponectin level. Drugs also increased GLUT4 and PPARγ protein expression compared with MS control group. Nigella sativa and ginger ameliorated parameters of MS via increased GLUT4 and PPARγ expression.
Mycoplasmosis remains one of the most expensive and common diseases facing poultry industry. The presence of Mycoplasma gallisepticum (MG) predisposes birds to other infections asEscherichia coli which together causes mortality, and sub-optimal performance. Therefore, this study was carried out to evaluate the efficacy of tilmicosin, apramycin and both drugs together on experimentally infected chicken with local field isolates of MG only or with E. coli as CRD and CCRD treatments. The present investigation clarified that infected groups treated with both tilmicosin and apramycin showed additive or synergistic interaction between them, which in turn confirmed the safety use of this combination therapy. The use of the recommended therapeutic dose of tilmicosin (1ml/L) or apramycin (0.5gm/L) alone or in combination for 5 successive days after appearance of the clinical signs are of considerable value in the treatment of MG infection in broiler chickens as antimycoplasmal drugs through displayed valuable improvement in clinical symptoms, survival rate, lesion scoring and termination of infection by the mycoplasmacidal effect of both drugs. The results also indicated that combined tilmicosin-apramycin therapy as antimicrobial drugs givesThe Effect Of Tilmicosin And Apramycin Alone Or ...
The pharmacokinetic properties of difloxacin were investigated following intravenous, intramuscular and oral administration of 10 mg/kg body weight, in non-infected and experimentally mycoplasma infected chickens. Serum concentrations of difloxacin were assayed microbialogically after intravenous, intramuscular and oral administrations. difl-oxacin residues were detected in chicken tissues following repeated oral administrations in non-infected and infected chickens. Following a single intravenous injection, the serum difloxacin level was best approximated to follow a two-compartment open model. The elimination half-life (t0.5) was 4.58 + 0.008 h. The volume of distribution at steady-state (Vdss) was 2.12 + 0.07 L/kg and the mean residence time (MRT) was 3.91 + 0.07 h.
