PREFACE This is an independent report of the In Vitro Acute Toxicity Peer Review Panel (" Panel ") The ICCVAM and the Acute Toxicity Working Group (ATWG) will consider the Panel report, along with public comments, to prepare final test method recommendations for U.S. Federal agencies. ICCVAM test method recommendations will be forwarded to U.S. Federal(More)
The present study examined the relationship between 24-hr urinary catecholamine (norepinephrine and epinephrine) output and measures of platelet adenylate cyclase (AC) activity in depressed patients (n = 17) and control subjects (n = 10). In both groups, significant inverse correlations were observed when 24-hr urinary catecholamine levels were examined in(More)
Pretreatment 24 hr urinary 3-methoxy-4-hydroxyphenylglycol (MHPG) levels and the Depression-type (D-type) scores (derived from a multivariate discriminant function equation based on levels of urinary catecholamines and metabolites) were examined as possible predictors of antidepressant responses to either imipramine or alprazolam. In the case of imipramine,(More)
The authors present preliminary data showing that pretreatment levels of urinary 3-methoxy-4-hydroxyphenylglycol (MHPG) were significantly higher in six depressed patients who responded to the antidepressant effects of alprazolam than in six depressed patients who showed no antidepressant response.
Demonstration of oligoclonal bands by electrophoresis of cerebrospinal fluid is an important aid in establishing the diagnosis of multiple sclerosis. Electrophoretic systems vary in their effectiveness in doing so. We compared two systems in this respect. For a thin-layer agarose system, sensitivity was less (47%) than for a high-resolution agarose system(More)
Data on 24-hour urinary levels of catecholamines and metabolites were determined in 114 depressed patients. For each patient, a D-type score was calculated, using a discriminant function equation that was previously derived using data from an independent group of depressed patients. Of all measures, D-type scores provided the highest sensitivity and(More)

We describe the case of an elderly woman whose symptoms and electrocardiographic pattern initially suggested acute myocardial infarction. The value for total serum creatine kinase (EC 2.7.3.2; CK) was 737 U/L (reference interval: 22-269 U/L), and electrophoresisfor CK isoenzymes demonstrated two bands, the more anodal migrating to the CK-MB region and the(More)
We have developed an HPLC technique which is precise, rapid and reliable. Sample preparation involves simple alkaline extraction into an organic solvent mixture. Trazodone elutes at 3.2 min in this reverse phase system. There is no requirement for elevated column temperature. The method is linear to 3000 ng/ml. The availability of a technique which is(More)
