Postnatal caffeine treatment affects differently two pentylenetetrazol seizure models in rats

Effects of repeated postnatal administration of caffeine (10 and 20mg/kg s.c. daily from P7 to P11) were studied in two models of epileptic seizures characterized by spike-and-wave EEG rhythm in 18- and 25-day-old rats. Rhythmic metrazol activity (RMA, model of human absences) was induced by low dose of pentylenetetrazol (PTZ, 20mg/kg or 40mg/kg, i.p.) and minimal clonic seizures (model of huma...

Different effects of postnatal caffeine treatment on two pentylenetetrazole-induced seizure models persist into adulthood.

BACKGROUND Postnatal treatment with caffeine from P7 to P11 (10 or 20 mg/kg daily) resulted in transient changes in two pentylenetetrazole (PTZ)-induced models of epileptic seizures characterized by spike-and-wave EEG rhythm in immature rats. To know if some changes persist into adulthood we studied these models in young adult Wistar rats. METHODS Caffeine treatment at a daily dose of 10 and/...

Chronic Treatment by L-NAME differently Affects Morris Water Maze Tasks in Ovariectomized and Naïve Female Rats

Introduction: The role of ovarian hormones and nitric oxide (NO) in learning and memory and their interaction has been widely investigated. The present study carried out to evaluate different effect of L-NAME on spatial learning and memory of ovariectomized (OVX) and sham operated rats. Methods: 32 rats were divided into 4 groups: 1) Sham 2) OVX 3) Sham-LN and 4) OVX-LN. The animals of groups 3...

Postnatal inflammation increases seizure susceptibility in adult rats.

There are critical postnatal periods during which even subtle interventions can have long-lasting effects on adult physiology. We asked whether an immune challenge during early postnatal development can alter neuronal excitability and seizure susceptibility in adults. Postnatal day 14 (P14) male Sprague Dawley rats were injected with the bacterial endotoxin lipopolysaccharide (LPS), and control...

Dextromethorphan affects ventilation differently in male and female rats.

Subcutaneous administration of aspartic acid results in a long-lasting but reversible depression of ventilation in male but not in female rats. Aspartic acid acts on N-methyl-D-aspartate receptors. The present study tested the hypothesis that a noncompetitive N-methyl-D-aspartate-receptor antagonist, dextromethorphan (Dex), would depress ventilation in female rats and stimulate it in male rats....
