ABSTRACT
ObjectiveTo study the regularity of the changes and the role of serum ionized Calci um in the pathogenesis of hemorrhagic fever with renal syndrome(HFRS). MethodsSerum was detected at different stages of HFRS by selective electrode, and analized the relationship between serum with blood urea Nitrogen and creatinine. ResultsSerum was much lower (P＜0.05) during hypotension shock stage and diuretic stage, and significantly lower(P＜0.01) during oliguria stage. The decrease of serum level was correlated to the state of illness aggravated. There is a negative relativity between serum and blood urea Nitrogen and creatinine (P＜0.01) in the patients. ConclusionSerum levels in patients may be related to the severity of the disease and renal function.
