Abstract:
Urinary lactate dehydrogenase (U-LD) isozyme assays were performed by cellulose acetate electrophoresis on the patients with clinically proven upper urinary tract infection (U-UTI) (N=21), lower urinary tract infection (L-UTI) (N=l5) and undetermined site of urinary tract infection (N =l4) as well as normal controls(N=l5). The results of this study are summarized as follows: * Total U-LD in normal controls (73.8 +/- 37.4 U/1) was significantly lower than in patients with upper UTI (145.9 +/- 86.8 U/I(p<0.01) or lower UTI (126.3 +/- 88.4 U/I) (p<0.05). * In normal controls and patients with L-UTI, LDI and LD2 predominated ('fast zone' pattern), and in patients with U-UTI, mainly LD5 and LD4 predominated('slow zone' pattern).
