(1973)When nucleic acids are catabolized by the rat, most of the purine moiety is excreted in the urine as allantoin. The amount excreted has been found to be higher under physiological conditions associated with increased protein ...
-
(1974)In iodine-deficient subjects the T3 and T4 peripheral metabolism was studied. A diminished disposal rate of T4 and an increase in T3 were found. Serum concentrations and disposal rates of both hormones were determined ...
-
(1974)A previous report based on investigations in Mexico suggested that quingestanol acetate might have potential as a postcoital oral contraceptive at a 800 mcg dose. This concept was based on some 1,000 cycles of therapy with ...
-
(1974)The influence of sodium salicylate, di- pyrone and indomethacin on the electroencephalographic effect of morphine was quantitatively studied in rabbits bearing chronically implanted electrodes. Salicylate alone produced a ...
-
(1973)Data concerning the evolution of SCP in the rabbit cortex during learning are presented. Unpolarizable electrodes were implanted in nine Ss at different sites of motor and somato-sensory cortex. These animals were trained ...
-
(1968)Two distinct fiber systems are recognizable in the dorsal lateral geniculate nucleus of the rat. One consists of small bundles running in a transverse plane from the ventrolateral to the dorsomedial parts of the nucleus, ...
-
(1973)The effect of chronic halothane inhalation and blood ethanol elimination was studied in the rat. Hepatic α glycerophosphate, oxidase ADH and malic enzyme activities were determined. Malic enzyme activity was also assayed ...
-
(1973)Experiences are discussed in the treatment of vesical sequelae from tuberculosis through ileocecocystoplasty, using Gil Vernet's technique, which provided for a satisfactory evaluation in seven of the eleven cases treated. ...
-
(1972)In contrast to experience in New York where the frequency of triiodothyronine (T3) toxicosis among hyperthyroid patients is 4%, 56 (12·5%) of 449 patients in Chile, an area of iodine deficiency, were hyperthyroid by clinical ...
-
(1973)A trial was conducted in naturally-occurring disease to compare the efficacy of treatment with trimethoprim-sulfamethoxazole (TMP-SMZ) with oral chloramphenicol. The majority of patients treated with TMP-SMZ (79%) responded ...
-
(1973)Synovial fluid from a patient with ochronotic arthropathy and calcification of the capsule of the right knee contained calcium pyrophosphate crystals and dark debris. Microscopic examination of an unstained fresh preparation ...
-
(1972)Since iodine deficiency induces in the plasma a rise in the concentration of T3 and a proportional fall in the concentration of T4, the disposal rates of both hormones and the thyroid function were studied in iodine deficient ...
-
(1973)Eine anfängliche Analyse der Wirkung der Vinca rosea L. Alkaloide wurde an induzierten Degenerationen von Rattenspermatogonien durchgeführt. Trotz der höheren mitotischen Indices der Typen B und In war die Degeneration ...
-
(1972)Serial fetal heart rate (FHR) determinations were made from early pregnancy to term in 24 healthy fetuses by means of an ultrasonic device. A decreasing FHR pattern was noticed from the eleventh through the thirtieth weeks, ...
-
(1972)Neural activity in the torus semicircularis (colliculus) of the frog was studied. Tones of different frequency, intensity, and duration were used for stimulation of each ear or both ears simultaneously. Unit responses were ...
-
(1968)Cytotoxic agents, cadmium, iodoacetate, thio-TEPA, podophyllin, colchicine, and alcohol, were instilled in one uterine horn of the rat to observe their subsequent effect on fertility. Cadmium and iodoacetate interfere with ...
-
(1971)Depth recording of photic evoked potentials of auditory and ectosylvian posterosuperior cortex of cat do not show reversal of polarity. Strychnine enhances only the auditory potentials. KCl has a depressor action on auditory ...
-
(1971)Variable proportions of four kinds of cones with different coloured oil droplets, are distributed in all retinal quadrants. Pigeons can learn and generalize colour recognition in any portion of their visual field. Since ...
