Thymoquinone ameliorates pulmonary vascular damage induced byEscherichia coli-derived lipopolysaccharide via cytokine downregulation in rats.

Our study investigated the ameliorative effects of thymoquinone (TQ) on the pulmonary blood vessels which were injured after intratracheal administration of Escherichia coli-derived lipopolysaccharide (LPS) in a rat model. Forty rats (150 ± 50 g) were randomly divided into four groups equally. The first group was intratracheally administered LPS (Escherichia coli O55:B5) at a dose 200 μg.

The effect of some natural alternative to antibiotics on growth and changes in intestinal histology in broiler exposed to Salmonella challenge.

This study was conducted to find the effect of different feed additives on the production performance and intestinal histology in Salmonella challenged birds. A total of 600 day-old-broiler chicks (Ross 308) were assignment to 10 treatments. Each treatment was further divided into 10 replicates.
