8 patients with chronic pyelonephritis were given gentamycin intramuscularly injected in individual dosage during 8-10 days. Here the behaviour of the excretion of protein, alanine aminopeptidase alkaline phosphatase, alpha-glucosidase, gamma-glutamyl transpeptidase and lysozyme with the urine was tested. With the exception of the lysozymuria, which increased only in patients with chronic renal insufficiency, regularly a hyperenzymuria developed. Most distinctly the excretion of the alanine aminopeptidase increased. After initial decrease the excretion of total protein transiently increased after completion of the gentamycin therapy. All the deviations were reversible. From the increased excretion of enzymes may not be concluded to a nephrotoxicity of gentamycin.

Normal values for a number of blood components of grivet monkeys are reported. Haematological data and values for glucose, cholesterol and urea are similar to those of rhesus monkeys. Activities of alkaline phosphatase (1526 U/l), glutamine oxaloacetate transaminase (30.9 U/l), glutamine pyruvate transaminase (13.7 U/l), lactate dehydrogenase (629 U/l), alpha-hydroxybutyrate dehydrogenase (175 U/l), creatine phosphokinase (227 U/l), gamma-glutamyl transpeptidase (38.7 U/l) and sorbitol dehydrogenase (14.2 U/l), and levels of lysozyme (178 mg/dl), zinc (162 microgram/dl), copper (81.3 microgram/dl) and iron (296.5 microgram/dl) have not previously been reported for this animal. Values for serum amino acids, proteins, electrolytes, triglycerides and creatinine are compared with those of other primates.

A description is given of an outbreak of equine infectious anaemia (E.I.A.) in Campania [at Naples and Aversa (Caserta)]; it was diagnosed by clinical, pathological and serological examinations (Coggins test). Using the serum of 45 horses with E.I.A. and 11 healthy horses (controls), numerous investigations were carried out on: enzymes, intrinsic coagulation factors, lipids and other substances. The results obtained were very interesting and show that in this disease there are significant increases in many enzymes (LDH, LAP, gamma-GT, CPK, PK and ALD) and copper. Insignificant increases were found in other enzymes (SDH, GLDH, MDH, ICDH, AIP, lysozyme, cholinesterase, GOT and GPT) and also intrinsic coagulation factors, lipid substances (total cholesterol, esterified cholesterol, triglycerides) and glucose. LDH-1-isoenzyme remains unchanged, whilst AcP decreases slightly.

This study is aimed to demonstrate that renal impairment caused by administration of amikacin (AMK) alone can be lessened by co-administration of piperacillin (PIPC). The patients in the present study were divided into three groups. In "group P" and "group A", PIPC alone and AMK alone were administered, respectively. In "group P+A", PIPC and AMK were co-administered. Dosage of AMK was individualized based upon the therapeutic drug monitoring method, and that of PIPC was adjusted depending upon the creatinine clearance of a patient. In group A, urinary concentrations of beta 2-microglobulin and lysozyme, and urinary excretion of beta 2-microglobulin, lysozyme and gamma-GTP per day were significantly higher (p less than 0.05) than those in group P. These differences were not observed, however, between group P and group P+A. The trough value of AMK, 11 days after AMK administration, was significantly higher in group A (p less than 0.05) than that in group P+A. Incidence of renal impairment, as judged from urinary excretion of beta 2-microglobulin per day and urinary lysozyme concentration, was significantly higher in group A (p less than 0.05) than that in group P+A. These findings indicate that co-administration of PIPC with AMK can lessen the renal impairment caused by administration of AMK alone.

The study was designed to evaluate (a) the role of reduced renal phosphate reabsorptive capacity assessed as the ratio of maximum capacity for renal phosphate reabsorption (TmPO4) to glomerular filtration rate (GFR) in the pathogenesis of hypophosphatemia in alcoholics, (b) possible mechanisms leading to reduced TmPO4/GFR, and (c) the effect of liver function impairment on TmPO4/GFR. The TmPO4/GFR, its major extrarenal determinants, ratios of urinary excretion gamma-glutamyl transpeptidase and of alpha-glucosidase to GFR (uGGT/GFR and uAGL/GFR), indices of structural damage of renal tubular cells, and fractional clearance of lysozyme, an index of proximal renal function, were evaluated in 31 alcoholics with alcohol-related liver disease, 24 alcoholics without alcohol-related liver disease, 14 patients with non-alcohol-related liver disease, and 25 control subjects. Hypophosphatemia was found in 35% of alcoholics with alcohol-related liver disease, 29% of alcoholics without alcohol-related liver disease, and no patients with non-alcohol-related liver disease. A reduced TmPO4/GFR was the major determinant of hypophosphatemia in both groups of alcoholics. No difference in extrarenal determinants of TmPO4/GFR was found between alcoholics with and without hypophosphatemia. Alcoholics with and without alcohol-related liver disease had increased uGGT/GFR and normal uAGL/GFR regardless of serum phosphate level. Fractional clearance of lysozyme, instead, was increased only in hypophosphatemic alcoholics with and without alcohol-related liver disease. The TmPO4/GFR correlated inversely with the fractional clearance of lysozyme in both groups of alcoholics (P less than 0.01). The TmPO4/GFR and urinary enzymes were normal in patients with non-alcohol-related liver disease. It was concluded that a reduced TmPO4/GFR is involved in the pathogenesis of hypophosphatemia in alcoholics. A proximal tubular dysfunction seems to be responsible for the reduced TmPO4/GFR. Liver function impairment is not required for the expression of this tubular dysfunction.

Few data are yet available comparing the histological patterns of cadmium nephropathy with the values of urinary enzyme excretions, useful indexes of renal tubular damage. 40 Wistar rats, divided into four groups (A-D), were intoxicated with cadmium chloride (CdCl2) at 16 ppm in drinking water for 4, 16, 40 and 60 weeks, respectively. At the end of each period all the intoxicated rats and 5 controls were assessed for creatinine clearance, fractional excretion of gamma-glutamyltransferase (UfrGGT) and alpha-glucosidase (UfrAGL), indexes of anatomical tubular damage, and for fractional clearance of lysozyme (CfrLys), index of functional tubular damage. Thereafter, the rats were sacrificed and their kidneys examined with light and electron microscopy. Control rats and group A and B rats did not show any histological impairment. A widespread vesiculation of proximal tubular cells with mitochondrial and lysosomal alterations was found in the group C rats and was more evident in group D. The brush border never showed any damage in all groups in accordance with the finding of a normal excretion pattern of UfrGGT, an enzyme situated in this structure. The UfrAGL was increased only in group D rats (p less than 0.025), who showed the most severe anatomical damages. The CfrLys, an index of tubular function, was elevated in group C and D rats (p less than 0.02 and p less than 0.002, respectively). It was possible to detect the initial renal tubular damage.

The following 10 enzymes were assayed in 187 amniotic fluid and maternal serum samples at 15-42 weeks of gestation: alkaline phosphatase, heat-stable alkaline phosphatase (only in amniotic fluid), acid phosphatase, alanine aminotransferase, aspartate aminotransferase, alpha-amylase, gamma-glutamyltransferase, creatine kinase, lactate dehydrogenase, and lysozyme. The normal reference ranges are reported for amniotic fluid and maternal serum enzymes, together with the abnormal values accompanying neural tube defects and EPH-gestosis. The determination of gamma-glutamyltransferase, heat-stable alkaline phosphatase and creatine kinase was found to be of appreciable diagnostic significance in clinical practice.

The urinary enzymes alanine amino-peptidase, alkaline phosphatase, gamma-glutamyltransferase and N-acetyl-beta-D-glucosaminidase and the two urine low-molecular mass proteins lysozyme and ribonuclease were measured in 30 healthy men and 36 insulin-dependent diabetics. 17 diabetics had "clinical proteinuria" (greater than 7.5 g/mol creatinine) and were defined as patients with manifest diabetic nephropathy. The remaining 19 diabetics were without proteinuria. The excretion rates of the two urine proteins and all enzymes except for gamma-glutamyltransferase were the highest in patients suffering from diabetic nephropathy. The excretion rates in both diabetic groups exceeded those of the control group. N-Acetyl-beta-D-glucosaminidase was more often increased than albumin in diabetics without manifest diabetic nephropathy. It is concluded that the tubular dysfunction is an early indicator of the incipient diabetic nephropathy. Thus, tubular parameters, especially the lysosomal enzyme N-acetyl-beta-D-glucosaminidase may be used in follow-up studies of diabetics.

Rat neutrophils added to 3H-labelled glomerular basement membrane (GBM) treated with rabbit anti-rat GBM antiserum degraded the GBM as judged by the release of 3H-labelled peptides. Cells from female animals promoted a more marked degradation than cells from males. This correlated with measurements of higher levels of elastase in granule fractions from the cells. The subcellular distributions of granule marker enzymes was found not to differ between the sexes. Levels of myeloperoxidase, lysozyme, cathepsin G, alkaline phosphatase, gamma-glutamyltranspeptidase and N-acetyl-beta-glucosaminidase showed no sex-based differences. No alpha-mannosidase could be detected in the cells.
