corticotropin-releasing hormone is a rapid and potent convulsant in the infant rat. | corticotropin-releasing hormone (crh) administered into the cerebral ventricles of rats during the first postnatal week caused a specific and stereotyped behavior sequence: rhythmic chewing and licking (jaw myoclonus) were followed by 'limbic'-type seizures. the onset of the seizures was much more rapid (2-45 min vs 3-7 h) than in adult rats, and the convulsant doses were much lower (50 x 10(-12) mol per gram brain weight vs 750 x 10(-12) mol per gram brain weight in adults). crh potency in indu ... | 1991 | 1914160 |
nasopharyngeal carcinoma with spinal secondaries. | nasopharyngeal carcinoma has been reported to have a higher incidence of distant metastases as compared to other head and neck cancers. distant metastases of nasopharyngeal carcinoma has been reported in the bones, lungs, liver, distant lymph nodes, brain and porta hepatis. this report presents a case of nasopharyngeal carcinoma with secondaries in the extradural space at the thoracic level of the spinal cord which hitherto has been an unreported site. | 2007 | 1919352 |
observation and theory in psychoanalysis: the self psychology of heinz kohut. | the development of self psychology by heinz kohut illustrates the influence of observational method on theory formation in psychoanalysis. in 1959 kohut began to emphasize empathy and introspection over the traditional combination of free association and evenly suspended attention. this became an important part of a process of revision in psychoanalytic theory which culminated in self psychology. this paper demonstrates how and why that particular change in observational method influenced that p ... | 2007 | 1924603 |
central nervous system involvement during infection by phlebovirus toscana of residents in natural foci in central italy (1977-1988). | central nervous system (cns) involvement was detected during infection caused by the sand fly-transmitted phlebovirus toscana. one hundred fifty-five cases of toscana virus-associated meningitis or meningoencephalitis were identified in a survey that lasted ten years, conducted in two regions of central italy. diagnosis was performed by different serologic tests. a combination of hemagglutination-inhibition and plaque-reduction neutralization or indirect immunofluorescence for igm, and enzyme-li ... | 1991 | 1951851 |
