-
(1993)The absolute biovailability of a sustained release tablet developed in our laboratory was evaluated. The formulation employs acrylic resins Eudragit as the sustaining release system and tablets were obtained using conventional ...
-
(1993)1. Liver microsomes from alloxan or streptozotocin diabetic rats displayed differential drug metabolizing abilities in vitro. 2. Only streptozotocin liver microsomes exhibited changes in the cytochrome P-450 normal spectral ...
-
(1993)When the rat kidney is subjected to ischemia and reperfusion, changes in glutathione content and in lipid peroxidation are produced in the cortex and in the medulla. The cortex shows a decrease in the glutathione content ...
-
(1993)The chronic daily administration of isoproterenol provokes in mouse parotid glands the induction and progressive accumulation of a family of secretory polypeptides named polypeptides C, D, E, F, and G (polypeptides C- G). ...
-
(1993)Microsomal lauric acid 12-hydroxy lauric acid (ω)-hydroxylation and fatty acid peroxisomal β-oxidation were studied in kidney tissue from starved rats. Starvation increased the microsomal ω-hydroxylation and peroxisomal ...
-
(1993)An investigation of the influence of the aggregate sizes on some elements of an oxisol is presented. Proton Induced X-ray Emission (PIXE) has been used to carry out this analysis. Aggregate sizes from <0.5 mm to 4.7 mm ...
-
(1993)1. 1. The antinociceptive action of calcium channel blockers administered intracerebroventricularly to mice using the acetic acid writhing test was studied. 2. 2. The drugs produced dose-dependent inhibition of the number ...
-
(1993)1. 1. The formalin test and R-III nociceptive electromyographic reflex were used to determine the origin of analgesia induced by ketorolac tromethamine (KT) in rats. 2. 2. The effects of KT and morphine were compared after ...
-
(1993)1. 1. In the present study, adenosine modulation on the antinociceptive action of benzodiazepines (BZD) using the writhing test in mice was evaluated. 2. 2. The i.c.v. BZDs tested (diazepam, midazolam and lorazepam) induced ...
-
(1993)Four sodium polysoaps from poly[malcic anbydride-co-styrene] were synthesized and the surface properties of their aqueous solutions at the air-water interface were determined. The surface tension lowering was directly ...
-
(KLUWER ACADEMIC PUBL, 1993-01)Santiago is a city of over 4.5 million inhabitants and about 415000 motor vehicles using leaded gasoline. Twenty-four-hour samples were taken of total and fractionated particulate matter using a low-volume system and two ...
-
(ELSEVIER SCIENCE BV, 1993-02-01)D-Glucosamine and ammonia, 1,2-ethylenediamine, or 1,10-phenanthroline form complexes with Co(III)*. The complexes are: [Co(NH3)3-H2O-D-glucosamine]3+, [Co(en)2.D-glucosamine]2+ and [Co(phen)2.D-glucosamine]3+. Formation ...

-
(GUSTAV FISCHER VERLAG, 1993-04)Antibodies raised against Trichoderma harzianum conidia prevented accumulation of Phenylalanine ammonia-lyase (PAL, E.C. 4.3.1.5.) in Citrus. The observed effect of the antibodies is produced by a delay in the formation ...
-
(MUNKSGAARD INT PUBL LTD, 1993-09-15)The crystal consists of discrete dimeric units, di-mu-chloro-bis[chloro(4,4'-dimethyl-2,2'-bipyridine)copper(II)] hydrate, linked to one water molecule and to another unit by van der Waals forces. Each dimeric unit contains ...
-
(SPRINGER VERLAG, 1993-11)Methyl methacrylate and methyl acrylate were grafted onto chitosan by using potassium persulfate alone as redox initiator and in combination with MnCl2 and CuCl2, as inorganic, and both ammonium tartrate and oxalate as ...
-
(DUSTRI-VERLAG DR KARL FEISTLE, 1993-11)Food-induced changes on the bioavailability of a sustained-release theophylline tablet, which uses acrylic resins Eudragit as sustaining agent, were studied in 12 healthy male volunteers. The tablet was developed in our ...
-
(ELSEVIER SCIENCE BV, 1993-11-15)A continuous-flow sensor based on integrated separation and spectrophotometric detection was developed for the determination of sulphur dioxide at the ng ml-1 level by transient immobilization of the reaction product formed ...
