the effects of constant light on eeg and seizure activity in the epileptic baboon.the effects of a change from a standard photoperiod (12:12 ld, 45 fc) to that of constant low level illumination (ll, 5 fc) on electroencephalographic activity (eeg), photic seizures and urine cortisol excretion were investigated in the baboon papio papio. unlike the normal circadian cycle, in which maximal urine cortisol excretion occurred at 08.00 h and minimal at 20.00 h, rhythms in cortisol excretion were free running under constant light, shifting an average of 2 h/week toward an earlier ti ...19826179743
characteristics and origin of frontal paroxysmal responses induced by light stimulation in the papio papio under allylglycine.in the papio papio, curarized and rendered photosensitive by injection of a subconvulsant dose of dl-allylglycine, single flashes induce frontal paroxysmal evoked responses on condition that they be preceded by trains of intermittent light stimulation (ils). the characteristics of these responses have been compared to those of non-paroxysmal responses induced in the same cortical area by isolated flashes (not preceded by trains of ils). the paroxysmal responses resemble spikes and waves and cons ...19826177492
opposite effects of lorazepam on two kinds of myoclonus in the photosensitive papio papio.the action of lorazepam was studied in photosensitive baboons. animals were either naturally very photosensitive or rendered photosensitive by a previous injection of allylglycine. intravenous administration of varying doses, from 0.05 to 0.5 mg/kg, of lorazepam blocked the myoclonus induced by intermittent light stimulation in all the animals. however, in the naturally photosensitive baboon the injection of lorazepam favoured the appearance of spontaneous myoclonus with no important eeg modific ...19816172264
cortical unit activity during intermittent photic stimulation in papio papio. relationship with paroxysmal fronto-rolandic activity.extracellular records have been made in the fronto-rolandic (fr), parietal and occipital cortical areas in papio papio injected with allylglycine and paralysed with a synthetic curarizing agent. the organization of the unit discharges in the absence of intermittent light stimulation (ils) is normal. during ils, unit discharges in the fr cortex are organized in bursts of high frequency that are synchronous with the spikes of the eeg paroxysmal discharges (pd) in the same territory; this burst-org ...19816166452
cerebral and extracerebral blood volume in generalized seizures in the baboon papio papio.relative variations of the cerebral and extracerebral blood volume (cbv) were measured continuously by a novel atraumatic method in baboons to explore the relationship between changes in the systemic circulation and in the cerebral (and extracerebral) vascular responses, before, during and after generalized seizures induced by photic stimulation. major bursts of generalized spikes and waves are accompanied by an increase of the mean arterial pressure and of the cerebral blood volume and a decrea ...19816161785

eeg and anticonvulsant effects of dipropylacetic acid and dipropylacetamide in the baboon papio papio.the ability of dipropylacetic acid (dpa) and dipropylacetamide (dpm) to modify eeg and seizure activity was assessed in 4 female and 3 male papio papio. doses of 30-60 mg/kg of dpa given at intervals over an 8 h period produced blood levels of 19-44 micrograms/ml which were not protective against intermittent light stimulation (ils). administration of 150-200 mg/kg doses at intervals over a 36 h period produced blood levels greater than 150 micrograms/ml and were highly protective against ils. s ...19806158417
evidence for neurotransmitter abnormalities related to seizure activity in the epileptic baboon.the experimental evidence that indicates that alterations in neurotransmitter activity exacerbate or diminish seizure responses to intermittent light stimulation in the papio papio model of epilepsy is reviewed. studies of the effects of drugs known to modify the synthesis, storage release, or activity of known or putative neurotransmitters are included. catecholamines, to a lesser extent the indolamine, serotonin, and the inhibitory transmitter gamma-aminobutyric acid all alter seizures as do l ...19846145626
antiepileptic action of excitatory amino acid antagonists in the photosensitive baboon, papio papio.antagonists of excitation induced by dicarboxylic amino acids have been evaluated for acute anticonvulsant activity in baboons, papio papio, with photosensitive epilepsy. 2-amino-7-phosphonoheptanoic acid, 1 mmol/kg, i.v., abolishes myoclonic responses for 5 h. less prolonged protection is seen after cis-2,3-piperidine-dicarboxylic acid, 1-3.3 mmol/kg; 2-amino-5-phosphonovaleric acid, 1-3.3 mmol/kg; or glutamic acid diethyl ester, 1-3.3 mmol/kg. toxic side-effects are prominent after the latter ...19836138738
differential effects of the benzodiazepine antagonist ro 15-1788 on two types of myoclonus in baboon papio papio.certain benzodiazepines (bzs) like lorazepam, diazepam or clonazepam induce myoclonus jerks in photosensitive and non-photosensitive baboons. papio papio, which are not accompanied by eeg paroxysmal discharges (type b). the effect of the selective bz antagonist r0 15-1788 was evaluated in this myoclonus. ro 15-1788 completely blocked type b myoclonus without decreasing the level of vigilance in the two types of baboons, and reversed the antiepileptic action of the bzs in the photosensitive ones, ...19836136945
[myoclonus induced by some benzodiazepines in the papio papio. comparison with myoclonus induced by intermittent light stimulation (author's transl)].papio papio may show two different kinds of myoclonus. a first type corresponds to myoclonus induced by photic stimulation (25 hz). this type is always preceded by paroxysmal discharges. another type of myoclonus may be induced, or at least facilitated, by some benzodiazepines, especially lorazepam and, to a lesser extent, diazepam. this type is neither preceded nor accompanied by paroxysmal discharges. a single injection of lorazepam (1 mg/kg i.v.) blocks the first type of myoclonus but favors ...19826125000
gamma-glutamyl transferase distribution in the organs of papio papio and macaca fascicularis.tissue distribution of non solubilized gamma-glutamyl transferase (ggt) was studied in eight baboons and ten macaques. in both, ggt is mainly in kidney, pancreas and liver. this tissue distribution of ggt is roughly similar to that observed in man.19806107384
conservation of the human col1a1-tk-gaa synteny and homoeologous assignment in the african green monkey and the baboon (cercopithecoidae).the pro alpha 1 (i) collagen structural gene (col1a1), the acid alpha-glucosidase (gaa), and the thymidine kinase (tk) genes, known to be closely linked in man (hsa) and mapped to hsa17, were found syntenic in two cercopithecoidae species, the baboon (papio papio, ppa) and the african green monkey (cercopithecus aethiops, cae) and assigned to homoeologous chromosomes, ppa16 and cae19, respectively. the assignment of col1a1 was obtained using two human cdna probes. hind iii restriction sites foun ...19846096258
gabaergic agents as anticonvulsants in baboons with photosensitive epilepsy.gabaergic agents have been evaluated for acute anticonvulsant activity in baboons, papio papio with photosensitive epilepsy. the potent gabaa agonists muscimol and thip are proconvulsant. (-)baclofen, 2 mg/kg suppresses myoclonic responses; higher doses facilitate eeg paroxysmal activity. (s) gamma-vinyl gaba, 100-200 mg/kg, suppresses myoclonic responses for more than 24 h. some derivatives of esters of beta-carboline-3-carboxylate that bind to the benzodiazepine receptor, e.g. zk 91296 and zk ...19846089055
