Comparison of creatinine and inulin clearances in multiple trauma
1990
Creatinine clearance (Ccr) is a good predictor of renal dysfunction. However, numerous analytical interferences have been observed with the classical measurement of creatinine by Jaffé's procedure. This prospective study was conducted to compare 4 methods for determining creatinine; and also endogenous creatinine clearance with inulin clearance (Cin) to estimate the glomerular filtration rate. The 4 different techniques for measuring creatinine were: 1) 2 techniques using Jaffé's colorimetric reaction: one with rapid and the other with slow kinetics: 2) 2 more selective methods: enzymatic procedure and high performance liquid chromatography (HPLC). Measurements were performed in 13 multiple…
Comparison of BT-PABA test and fecal chymotrypsin measurements in normal subjects and diabetic patients
1990
A N-benzoil-L-tyrosil-PABA test on 6h urine collection, a plasma PABA assay 2 h after administration and a fecal chymotrypsin assay were performed on 66 patients (36 controls and 30 type 2 diabetic patients on insulin therapy). All patients were hospitalized and without gastrointestinal and renal disease. The mean values of plasmatic PABA and fecal chymotrypsin were significantly lower in the diabetic group than in the controls (p less than 0.025 and p less than 0.01, respectively), although they remained within normal range. But this was not the case for PABA urinary excretion values. This may indicate a slower but more protracted PABA absorption during the third or fourth hour with the re…
THERAPEUTIC AND COLATERAL EFFECTS OF 25-HYDRXYCHOLECAICI FEROL IN VITAMIN D DEFICIENCY
1974
Vitamin D polar metabolite, 25–HCC has been used in 2 infant groups whose ages range from 0–18 months. In the 1st group of 15 infants, all of them suffered from rickets, clinically, biochemistry and radiologically and no prophylactic vitamin D administration could be demonstrated. The control group (15 infants too) was admitted with similar diseases but no one suffered from rickets. Routine determinations for metabolic assesment of Ca phosphoric metabolism were perforaed in plasma and in 240. urine collections, prior and after 25–HCC adBinietration. The rickets group received 20 mcg/day, orally for 20 days and the control 10mcg/day in the same way. The biochemical study demonstrated that bo…
