Out of 152 cases of Acute renal failure (ARF) 32 patients (21%) were subjected to kidney biopsy. All patients had intrinsic ARF. Prerenal azotemia and obstructive uropathy were excluded. Histologic observations were: Crescentric glomerulonephritis in 7 (21.9%), acute endocapillary proliferative glomerulonephritis 5 (15.6%), acute interstitial nephritis 7 (21.9%), necrotizing vasculitis 4 (12.5%), acute tubular necrosis in 5 (15.6%) and membrano-proliferative GN with superimposed crescent in 2 (6.2%) while renal cortical necrosis was seen in 6.2% of cases. Prebiopsy diagnosis was correct in only 10 (31.25%) cases. The result of biopsy had altered clinical diagnosis in 22 (68.75%) patients and precise renal biopsy diagnosis resulted in therapeutic changes in 54.8% of patients with ARF.

Ehrlich's test, serum mucoproproteins, phosphohexoisomerase (PHI), and lactate dehydrogenase (LDH) levels were studied in patients with cancer and age matched controls. All parameters studied were found to be significantly increased in cancer. Evaluation of Ehrlich's test, PHI and LDH for their validity as screening tests revealed that Ehrlich's test is better suited as a screening test for cancer. A positive correlation observed in the study between serum mucoproteins and Ehrlich's test strengthens the postulation that mucoproteins are responsible for the colour development in Ehrlich's test.
