    Notes: Abstract Early studies showed dramatic improvement in some depressed patients when a brief course of parenteral reserpine was added to ineffective tricyclic antidepressant (TCA) treatment. We treated eight patients with DSM-III melancholic major depression with desipramine (DMI)≥2.5 mg/kg/day (plasma levels〉125 ng/ml) for at least 4 weeks. All patients failed to respond and received reserpine 5 mg IM b.i.d. over 2 days, in seven cases as a placebo-controlled, double-blind trial. One patient had dramatic resolution of depressive and psychotic symptoms within 48 h, but relapsed within 2 weeks; two other patients had transient hypomanic symptoms. Depression ratings did not significantly change for the sample as a whole, but plasma and cerebrospinal fluid (CSF) levels of 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG) decreased and CSF levels of homovanillic acid (HVA) and 5-hydroxy-indoleacetic acid (5-HIAA) increased. Despite robust effects on central monoamine metabolism, reserpine augmentation appears insufficiently effective for routine use in managing refractory depression.

    Notes: To enhance utility of the linear epitope mapping (Pepscan) technique for assay of humoral responses linked to vaccination, two modifications were tested. First, peptides were incubated with serum contained in baths rather than individual wells. Second, a rigorous statistical model was developed to determine which peptide/antibody-binding interactions were significant. The modifications increased the ability to detect signal in these experiments by 15- to 45-fold. These two modifications were applied to linear epitope mapping of HIV seropositive volunteers under treatment with recombinant HIV gp160 and also to rabbits immunized with the same product. Changes in fine specificity of response were observed in animal models and human vaccine recipients over the course of an immunization series with this antigen.
