-
(1988)The apparent permeation rate constants and amount of ranitidine transferred in 1 h were measured through everted rat intestine using a perfusion apparatus. The effects of pH and 5% or 10% ethanol on the apparent permeation ...
-
(1988)The enthalpies of the reaction between glutathione and amoxycillin have been measured directly using a flow microcalorimeter. Comparative results are obtained by using an ac polarographic method previously developed in our ...
-
(1988)1. 1. Intestinal clearances of flucloxacillin significantly decrease with the increase of pH, concomitantly with a decrease of the percent absorbed at 60 min. 2. 2. The apparent rate constants for unionized (Ku) and ionized ...
-
(Instituto de Investigaciones Agropecuarias, 1988-04)Dehydrogenase and respiratory activities were studies in six soils, five of volcanic origin and the other alluvial, as a reference. Dehydrogenases activity was measured by the reduction of 2, 3, 5- Tryphenyl Tetrazolium ...
-
(ROYAL SOC CHEMISTRY, 1988-06)An electrochemical study of the (+/-)-1-(2,5-DIMETHOXY-4-NITROPHENYL)-2-AMINOPROPANE, which differs from similar compounds in that a hydrophilic nitro group replaces hydrophobic substituents on the 4-position of the benzene ...

(Sociedad Chilena de Química, 1989)Se estudió la reacción de condensación de di-2-piridilmatano con los compuestos carbonílicos: benzaldehido, 2, piridilcarboxaldehido, acetona y di-2-piridilcetona, catalizada por sales de los metales de la primera serie ...
-
(National Institute of Health, 1989)Almost every week, it seems, another character appears, expending the cast of DNA-binding proteins. Some of these proteins are destined for major roles, binding to DNA sequences a few hundred basepairs upstream of key ...
-
(American Chemical Society, 1989)The exchange between bromide and chloride counterions at the surfaces of dioctadecyldimethylammonium vesicles has been examined through fluorescence quenching experiments. The quenching of the fluorescence of vesicle-incorporated ...
-
(Colegio Químico Farmacéutico de Chile, A. G., 1989)La importancia del tema se debe a la especial relación entre alimentos y enzimas. Las enzimas, catalizadores bioquímicos, cumplen diversas funciones en los alimentos, provocando en algunos casos, graves daños en el color, ...
-
(1989)The changes in the acquisition of conditioned avoidance responses (CARs) and the performance of some spontaneous behaviors were examined across the estrous cycle of female rats. CARs were facilitated during diestrus, ...
-
(1989)A 300 mg controlled-release theophylline formulation was developed as a tablet prepared by wet granulation using the acrylic resins Eudragit S 100(R) and Eudragit RSPM(R). The tablet was compared with a marketed ...

-
(1989)Abstract The quenching of the benzophenone triplet by lysozyme and its constituent amino acids in aqueous solutions have been studied. Native lysozyme quenches the benzophenone triplet with a high rate constant, 4 × ...
-
(1989)1. The in vivo effect of estradiol and domperidone (a hypophysis stimulator of prolactin secretion) in immature ovariectomized-adrenalectomized and hypophysectomized rat mammary gland was studied. 2. γ-Glutamyltranspeptidase ...
-
(1989)This note presents measurements of the electric charge in a Nuclepore filter attained with a simple device able to detect induced charge in a metallic plate which is registered through a 610B KEITHLEY electrometer. A ...
-
(1989)Nifurtimox disposition was evaluated in 7 healthy volunteers. Each subject received an oral dose of 15 mg/kg of nifurtimox and blood sample was obtained 11 h after the drug administration. We used an analytical method ...
