Abstract:
Objective To study the radiation effects on the serum concentration of urea nitrogen (BUN), creatinine (Cre), ?2-microglobulin (?2-MG) and uric acid (UA), and to evaluate the injuries to renal function induced by a 60 Co irradiation accident in Shandong province. Methods The concentrations of urea nitrogen, serum creatinine and serum uric acid were determined by enzymatic methods. The concentrations of serum ?2-microglobulin were determined by the immunoturbidity methods using HITACHI 7170s automatic biochemical analyzer. Results The serum concentrations of BUN and Cre of 2 patients increased significantly after irradiation, and the serum concentration of UA in the two cases elevated too after irradiation, but didn't reach the normal value. The serum concentrations of ?2-microglobulin also increased significantly after irradiation. In case A which received 20~25Gy irradiation, the concentrations of serum BUN, creatinine and ?2-microglobulin increased to 41.63mmol/L, 364?mol/L and 9.2mg/L, respectively. In case B which received 9~15Gy irradiation, the concentration of serum BUN, creatinine and ?2-microglobulin increased to 52.2mmol/L, 199?mol/L and 11.3mg/L, respectively. There seemed a dosage-dependent effect on the BUN, Cre and ?2-microglobulin concentration. Conclusion 60 Co may irradiate the tissues of kidney directly, and irradiate the cells of other tissues and organs, lead to necrosis and degenerations accordingly on the tissues of kidneys and other organs. In the process of necrosis and degenerations, a large amount of metabolic products was released which is poisonous to the kidney. The present results showed the concentrations increased of all the four renal serum markers mentioned above. It is supposed that the renal cells might be damaged by the Cobalt ? ray irradiation.
