ABSTRACT
Quantitative estimation of proteinuria done by the refractometric method was compared with that done by the sulphosalycilic acid method and biuret method in 102 urine samples. The analysis of results by students' t test showed no statistically significant difference between the three methods. It is concluded that quantitative estimation of urinary protein excretion by refractometric method is a simple cheap and reliable method and can be performed easily in the outpatient clinic. The instrument is quite handy and can be carried in the pocket.

Paraquat poisoning is relatively rare and is associated with mortality varying from 35 to 50%. A patient who consumed paraquat developed features of non-oliguric acute renal failure and recovered following haemodialysis. Renal biopsy done during the early recovery phase showed features of acute tubulo-interstitial nephritis with no disruption of tubular basement membrane. On recovery the patient had no evidence of proximal renal tubular dysfunction.
