THE EFFECTS OF ANGIOTENSIN-CONVERTING ENZYME-INHIBITORS ON THE CLINICAL AND BIOCHEMICAL PARAMETERS IN DIABETIC NEPHROPATHY
(MARCEL DEKKER INC, 1993)Captopril's short-term effects on clinical and biochemical parameters were studied in 21 diabetic nephropathic patients. Their mean age was 57.50 +/- 2.28 years; 16 of them were women and 5 were men. Eleven patients had ... -
THERMAL-DEGRADATION OF BLENDS OF PVC WITH POLYDIMETHYLSILOXANE
(ELSEVIER SCI LTD, 1993)The thermal degradation of blends of PVC with polydimethylsiloxane (PDMS) has been studied by thermogravimetry (TG) over the whole composition range and by thermal volatilisation analysis (TVA) for 1:1 by weight blends. ... -
EFFECTS OF PROPOFOL ON VASCULAR SMOOTH-MUSCLE FUNCTION IN ISOLATED RAT AORTA
(J R PROUS SA, 1994)This study was undertaken to determine the direct actions of propofol, and whether propofol exerts any action on basal endothelium-derived relaxing factor release and vasodilator effect of acetylcholine on phenylephrine-induced ... -
THE SECONDARY NASAL MIDDLE CONCHA
(SPRINGER VERLAG, 1994)In this study a total of 175 coronal CT scans of the nasal cavity and paranasal sinuses have been investigated. A secondary middle concha was detected bilaterally in 12 (6.8%) out of 175 patients. In all cases, the ethmoidal ... -
PLASMA-FREE CARNITINE LEVELS IN CHILDREN WITH MALNUTRITION
(TURKISH J PEDIATRICS, 1994)In this study, plasma free carnitine and albumin levels were measured in children with protein-energy malnutrition (PEM). A total of 71 children with malnutrition were studied. The control group consisted of 20 healthy ... -
AN AUTOPSY EVALUATION OF DEFENSE WOUNDS IN 195 HOMICIDAL DEATHS DUE TO STABBING
(FORENSIC SCIENCE SOC, 1994)Defence wounds may be of value in differentiating between homicide, suicide and accidental death. A study of 3183 forensic autopsies in Istanbul between 1988 and 1989 showed that 195 deaths (6.1%) were due to stab wounds, ... -
DETERMINATION OF CEFTRIAXONE IN AQUEOUS-HUMOR AND SERUM SAMPLES BY DIFFERENTIAL-PULSE ADSORPTIVE STRIPPING VOLTAMMETRY
(ROYAL SOC CHEMISTRY, 1994)Differential-pulse adsorptive stripping voltammetry was used to determine ceftriaxone in serum and aqueous humour samples. The method involved extraction of the ceftriaxone from serum samples with an Amberlite XAD-2 column ... -
INTRAVENOUS IMMUNOGLOBULIN IN THE TREATMENT OF SALMONELLA-TYPHIMURIUM INFECTIONS IN PRETERM NEONATES
(WESTMINSTER PUBL INC, 1994)The purpose of this study was to determine the role of intravenous immunoglobulin (IVIG) administration in preterm neonates with S. typhimurium infection. A randomized trial of 47 preterm neonates with intestinal or ... -
AN ANALYTICAL APPROACH TO OBTAINING A VALID SOLUTION TO THE SECULAR EQUATIONS FOR CIS-DISUBSTITUTED OCTAHEDRAL METAL-CARBONYLS
(PERGAMON-ELSEVIER SCIENCE LTD, 1994)Using an analytical approach we have been able to obtain a valid solution to the secular equations for cis-ML2(CO)4 molecules. The solution has led to the relations by which carbonyl stretching force constants and interaction ... -
THE EFFECTS OF UNDERNUTRITION ON CONNECTIVITY IN THE CEREBELLAR CORTEX OF ADULT-RATS
(CAMBRIDGE UNIV PRESS, 1994)The effects of a 30 d period of undernutrition, followed in some animals by nutritional rehabilitation, on neuronal connectivity in adult rat cerebellum were investigated using the disector method. There was no significant ... -
