Introduction: We have been exploring the effects of dihydroprogesterone in female amygdala-kindled rats. For intraperitoneal (i.p.) time-response studies, we used a vehicle containing the common solvent, benzyl alcohol (BnOH). The vehicle containing BnOH was also tested alone as a control.
A 53-year-old African-American man with relapsed non-Hodgkin's lymphoma developed seizures and respiratory arrest 2 hours after an infusion of high-dose etoposide in preparation for an autologous bone marrow transplant. Laboratory tests revealed both rapid hemolysis and severe metabolic acidosis.
Phenol has various medical applications but can cause convulsions and cardiac arrhythmia suggestive of K+ channel block. We examined phenol inhibition of the delayed-rectifier RCK1 (Kv1.1) K+ channel cloned from rat brain and expressed in Xenopus laevis oocytes. Phenol (2.5 mM) caused a 43 +/- 5 mV
The prevalence of kernicterus in our neonatal intensive care unit (NICU) decreased from more than 2/1000 live births in 1980 to none in 1984. To clarify predictors of kernicterus, we examined the medical records of infants born during that time who died between 2 and 28 days of age. Infants were
Drug tolerance and withdrawal are insidious responses to drugs of abuse; the first increases drug consumption while the second punishes abstention. Drosophila generate functional tolerance to benzyl alcohol sedation by increasing neural expression of the slo BK-type Ca(2+) activated K(+) channel
Carbamazepine (CBZ) could be dissolved in Glycofurol (polyethylene glycol monotetra-hydrofurfuryl ether) with concentrations up to 100 mg/ml, and the solutions were stable for at least 14 days. Ethanol or benzyl alcohol was added without loss in solubility, while water, human serum albumin or
Gamma-hydroxybutyrate (GHB) is an increasingly popular drug of abuse that causes stimulation, euphoria, anxiolysis or hypnosis, depending on the dose used. Low doses of the drug are used recreationally, and also implicated in drug-facilitated sexual assaults. Because of the unusually steep
Drug addiction is a complex condition of compulsive drug use that results in devastating physical and social consequences. Drosophila melanogaster has recently emerged as a valuable genetic model for investigating the mechanisms of addiction. Drug tolerance is a measurable endophenotype of addiction
Recent research has shown that bursts of approximately 20 Hz fast waves are elicited in rhinencephalic cortex in rats by the odors of a number of different organic solvents and of components of the secretions of predators such as the weasel and the fox. We now show that a number of phytochemicals
The slo gene encodes the BK-type Ca(2+)-activated K(+) channels. In Drosophila, expression of slo is induced by organic solvent sedation (benzyl alcohol and ethanol), and this increase in neural slo expression contributes to the production of functional behavioral tolerance (inducible resistance) to
OBJECTIVE
The excipients benzyl alcohol, propylene glycol and ethanol are present in medications used in the neonatal intensive care unit. Exposure to high levels can have adverse effects in a neonatal population. The objective was to quantify excipient exposure in very low birth weight (VLBW)
Thirty-five neonates with sensorineural hearing loss (SNHL), identified by brainstem auditory evoked response (BAER), and 70 matched controls with normal BAERs were studied. All infants had had BAERs before discharge from hospital as part of a screening program for high-risk neonates. Infants with
