Repeated Blood Collection from Tail Vein of Non-Anesthetized Rats with a Vacuum Blood Collection System

Blood can be collected from rats in a number of sampling locations. For instance, the tail vein is a superior location for blood sampling. However, the ...

We previously reported significantly enhanced cardiac remodeling post aortocaval fistula (AV) in unilateral nephrectomized (UNX) rats. However, the relationship between the size of the AV and the cardiorenal effects in UNX rats remains unknown. In the present study, AV was induced by 20, 18 and 16 gauge needles in UNX rats to see if larger shunt would definitely induce heavier cardiac and renal damage in UNX rats. Our results demonstrated that bigger shunt size is linked with proportional more significant cardiorenal remodeling and dysfunction in UNX rats. Expression of inflammatory biomarkers including CRP, TNF-α, IL-6, IL-1β, TGF-β and MCP-1 in left kidney and heart was significantly increased in all UNX + AV groups compared to Sham rats. Inflammation might thus participate in the worsening cardiorenal functions and remodeling processes in this model.
