Status epilepticus is a medical emergency requiring immediate treatment. General treatment is aimed at restoring physiologic homeostasis, and drug therapy is aimed at arresting the convulsive activity and preventing its recurrence. Concurrent administration of diazepam and either phenytoin or phenobarbital will be effective in most cases. After the status epilepticus has been treated the underl...

Rat cerebellar granule cells were cultured for 5 days with progesterone, resulting in the conversion of progesterone to allopregnanolone, a potent and efficacious modulator of gamma-aminobutyric acid (GABA) type-A receptors, as well as in decreases in the abundance of GABA(A) receptor alpha(1), alpha(3), alpha(5), and gamma(2) subunit mRNAs. These effects were accompanied by decreases in the ef...

Treatment of SE is based on the age of the patient and the possible underlying etiology. Initial treatment should include a benzodiazepine (lorazepam 0.1 mg/kg or diazepam 0.5 mg/kg). Specimens for laboratory tests should be drawn early in the event of a prolonged seizure and geared toward the clinical presentation and age of the patient. If a seizure lasts longer than 10 minutes, phenobarbital...

Quantitative determination of the cells excreted in the urine has until recently been regarded as a cumbersome and timeconsuming procedure (Lancet, 1961). Houghton and Pears (1957) attempted to simplify the technique, and McGeachie and Kennedy (1963) described a method of semi-quantitative cell counting which was suitable for routine use yet was much more accurate than the ordinary wet-film tec...

We investigated the effect of acute oral treatment with a water-alcohol extract of the inflorescence of Erythrina mulungu (EM, Leguminosae-Papilionaceae) (100, 200 and 400 mg/kg) on rats submitted to different anxiety models: the elevated T-maze (for inhibitory avoidance and escape measurements), the light/dark transition, and the cat odor test. These models were selected for their presumed cap...

Rats undergoing extinction of lever-pressing for food after the attenuation of an external feedback for this behavior, exhibit excessive lever-pressing unaccompanied by an attempt to collect a reward, which may be analogous to the excessive and unreasonable behavior seen in obsessive-compulsive disorder (OCD). Given that one of the most salient features of OCD is its selective response to treat...

In humans, a first night effect (FNE) is characterized by increased sleep latency and decreased total sleep time in an unfamiliar environment, but the mechanism and treatment options for this universally experienced acute insomnia are unclear. We continuously recorded electroencephalography (EEG) and electromyogram (EMG) and measured plasma corticosterone levels to develop a mouse FNE model by ...

The objective of the current paper was to review the literature and discuss the degree of evidence for various treatment strategies for status epilepticus (SE) in adults. We searched MEDLINE and EMBASE for relevant literature from 1966 to January 2005. Furthermore, the Cochrane Central Register of Controlled Trials (CENTRAL) was sought. Recommendations are based on this literature and on our ju...

Lippia alba (Mill.) N.E. Brown (Verbenaceae) is widely used in different regions of Central and South America as a tranquilizer. The plant's anxiolytic properties, however, merit investigation. The present study evaluated the effects of repeated daily (14 days) intraperitoneal (ip) treatment with an essential oil (EO) from a chemotype of L. alba (LA, chemotype II, 12.5 and 25 mg/kg; N = 6-8) an...
