Study of urologic exposure dose in selective organ's cell & behavior of Wistar rats

Abstract

Background

Radiologic fluoroscopy procedures have been imposing considerable exposure dose to staff with serious consequences relative to dose quantity which is still continuing as challenge of studies, hence the aims were to assess the animal behavior, quantify blood components and red blood cells morphology after exposure to x-ray urologic fluoroscopy doses (0.3, 0.8, 1.8 and 2.5 mSv).

Methods

urologic exposure doses measured by TLDs chips and TLD reader Model 5500 from selected hospitals. These doses used to expose Wister male rats weighted (275 ± 2.0 g). The collected data were animal behavior, quantity of blood components and cellular changes in RBCs, kidneys, liver & testicles then analyzed by SPSS- 20 (SPSS Inc., Chicago, IL, USA)

Results

showed that a dose of 2.5 mSv decreased significantly (p value = 0.00) the motor activity of rats. and the blood components decreased as follows: WBC (30.2%), Lymphocytes (40%.0), Neutrophils (35.7%), RBC (37.9%), MCV (32.2%) and RCDW (31.5%). At exposure dose of 0.3 mSv a mild morphological changes as circular shape deformity and loss of bi-concavity of RBCs. At 0.8 mSv RBCs diameter increment (10 ± 0.4 μm) and formation of spikes. At 1.8 mSv RBC underwent anisocytosis and poikilocytosis. While at 2.5 mSv the RBC showed intensive spikes, clustering and some underwent hemolysis. Morphological changes were induced also, at 2.5 mSv for the followings: The renal cortex showed bleeding & congestion at 2.5 mSv. The Renal medulla showed bleeding at 2.5 mSv. The liver texture showed bleeding and congestion with two nuclei- Kupffer cells hyperplasia, ballooning of hepatocytes with Acidophilic bodies at 2.5 mSv. the testicles tissues developed congestion and bleeding.

Conclusion

fluoroscopic urologic exposure dose can induce significant behavioral, RBCs changes and reduction in blood components.
