The Effects of Water Pipe Smoking onHematological Parameters in Rats

Objectives: this study aimed to investigate the effect of water-pipe (wp) smoking on hematologicalparameters of wistar rats.methods: thirty-five young male rats (200-250 g) were randomly assigned to five groups (n=7). the controlgroup was exposed to room air and the experimental groups were exposed to wp smoking, using a specialapparatus designed to have the ability to keep the rats for 40 minutes every day for 4, 8, 12 and 12 weeks;moreover, one of the two groups of 12 weeks of wp exposer had four following weeks of rest. blood sampleswere collected to evaluate red blood cell count, hemoglobin, hematocrit, white blood cell and platelet counts.results: the results showed that rbc count, hb and hct parameters were significantly higher in wp smokingrats than the control group (p< 0.001). we found that wbc counts insignificantly increased (p < 0.39) but pltcounts insignificantly decreased (p < 0.13) in wp smoking rats compared with control group.conclusion: the findings may help to raise awareness of tobacco smokers about the potential toxicities ofwp; likewise, the results can be used by physicians and public health officials in tobacco prevention programs.
