The contribution of serotonin neurons to the functional recovery after spinal cord injury was studied pharmacologically in rats with moderately severe neurologic impairment (complete paraplegia but responsive to tail pinching) 24 h after thoracic spinal cord (T11) compression-induced injury. Fourteen days after cord injury the levels of endogenous(More)
Stable ERG was successfully recorded using a contact lens-type electrode in conscious cynomolgus monkeys restrained in a monkey-chair with a specially devised head-holder. After adaptation to darkness, single photostimulation evoked ERG consisting of an initial negative wave (a-wave), followed by a positive wave superimposed with oscillatory potentials(More)
In the present study, the effects of a new anxiolytic, DN-2327, were compared to those of diazepam and buspirone in rats in the elevated plus-maze test. Two indices of anxiety were obtained in this test: the number of entries into the open arms expressed as a percentage of the total number of arm entries and the percentage of time spent on the open arms.(More)
Behavioral and EEG effects of 2-(7-chloro-1,8-naphthyridin-2-yl)-3-[(1,4)-dioxa-8-(azas piro-[4.5]dec-8- yl)carbonylmethyl]isoindolin-1-one (DN-2327; 1, 5 and 20 mg/kg p.o.) were compared to those of diazepam (0.2 and 1 mg/kg p.o.) and buspirone (1 and 5 mg/kg p.o.) in freely moving cats. DN-2327 did not affect motor coordination or the relative percentages(More)
Disrupted-in-Schizophrenia-1 (DISC1) is a gene in which a mutant truncation by a balanced t(1;11)(p42.1;q14.3) translocation is segregated with major psychiatric illness with a predominance of schizophrenic symptomatology in a large Scottish family. However, no functional polymorphisms have been detected that are associated with schizophrenia in general(More)
Sleep EEG of eight healthy males and eight females aged 54-72 years were recorded at their homes. The electroencephalograms were visually scored and analyzed by spectral analysis using the FFT method. There were no significant differences in sleep parameters except for a higher percentage of stage 3+4 in females. The spectral power of the delta band EEG was(More)
DN-2327, 2-(7-chloro-1,8-naphthyridin-2-yl)-3-[(1,4-dioxa-8- azaspiro[4.5]dec-8-yl)carbonylmethyl]isoindolin-1-one, produced anxiolytic, taming and anti-convulsive effects when administered orally to several species of animals. DN-2327 produced few of the sedative-hypnotic and muscle-relaxant effects observed with diazepam. The durations of the anxiolytic(More)
The effects of a new anxiolytic, (2-(7-chloro-1,8-naphthyridin-2-yl)-3- [(1,4-dioxa-8-azaspiro[4.5]dec-8-yl)-carbonylmethyl] isoindolin-1-one (DN-2327), on the execution of step-through passive avoidance and delayed spontaneous alternation tasks were assessed and compared with those of diazepam (DZP) and buspirone. DN-2327 and buspirone (both 10 and 20(More)
