    Notes: Abstract The adult population of a large mental hospital was screened for tardive dyskinesia (TD). Approximately 11% of the hospital population showed signs of TD; females and the elderly were over-represented in the TD group. A representative sample of those with TD was selected and a control (non-TD) patient was chosen to match each of the TD subjects in age, sex, length of hospitalization, diagnosis, and race. The charts of these subjects were searched for any indices of brain damage and the complete psychotropic medication history was recorded. There was no difference between the TD and controls in the amount of psychotropics ingested, in the duration of administration, in the kinds of drugs, or in the organicity history. Women as a group, however, tended to have more polypharmacy than men. The role of neuroleptics in TD is discussed as well as other possible etiological factors.

    Deanol in the treatment of tardive dyskinesia (1977)
    Springer
    Psychopharmacology 52 (1977), S. 257-261

    Topics: Medicine
    Notes: Abstract Ten hospitalized chronic psychotic patients with symptoms of tardive dyskinesia were given deanol and placebo, each for 8 weeks following a double blind, crossover design. No psychotropic agents were administered during the trial. Improvement occurred in all patients during the first treatment phase regardless of which drug the patients received; seven patients were on deanol and three on placebo during this time. The possible reasons for this decrease were discussed. It was concluded that deanol may have contributed to the decline but that its effect on the disorder was not dramatic.

    Clozapine in tardive dyskinesia (1978)
    Springer

    ISSN: 1432-2072
    Keywords: Clozapine ; Schizophrenia ; Tardive dyskinesia ; Parkinsonism ; Neutropenia ; Convulsions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Clozapine, which has had limited clinical testing in the U.S.A., was evaluated in 12 chronic schizophrenic patients with tardive dyskinesia. Its antipsychotic activity was again demonstrated and it suppressed the symptoms of tardive dyskinesia with a marked rebound occurring in these symptoms when it was withdrawn; there was no rigidity or other Parkinsonian symptoms. However, out of a total of 12 patients, neutropenia (800 and 1120) occurred in two patients, convulsions in one patient, marked withdrawal effects in three patients, and a hypotensive collapse with atrial fibrillation in one patient. If these adverse effects are confirmed in a larger sample size, then despite the novel desirable effects of clozapine it would seem unlikely that it will gain widespread or routine use1.

    Capillary electrophoresis separation of heterocyclic nitrosoamino acid-conformers at sub-ambient temperatures (1994)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 17 (1994), S. 753-755

    Keywords: Capillary electrophoresis ; Nitrosamines ; Subambient temperature ; syn and anti isomers ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The separation of a selected group of naturally occurring, heterocyclic nitrosoamino acids was achieved by capillary zone electrophoresis and the resolution of the syn and anti conformers improved as the temperature was lowered to 5 °C. The double peaks observed for each nitrosoamino acid are probably caused by the slow kinetics of conformational isomerism. The experimental setup consisted of a P/ACE 5510 electrophoresis system, a 57 cm polyacrylamidecoated capillary, and a 10 mM phosphate buffer, pH 7.2, containing 2 mM of 3-(N-N-dimethylmyristylammonio)propanesulfonate (DMMAPS) and 0.1% Tween 20. Our study shows that (a) the lower the temperature, the greater the resolution and the longer the migration times; and (b) different nitrosoamino acid conformers were resolved at different temperatures because of differences in the rate of isomerization. For example, the conformers of N-nitrosothiazolidine-4-carboxylic acid were partially resolved at 30 °C while those of N-nitrosoproline were well resolved at the same temperature.

    Detection of hydrogen-bonded supramolecular complexes using electrospray ionization from chloroform (1995)

    Notes: The stoichiometry of a noncovalent, hydrogen-bonded supramolecular complex, hub(M)3·RCA3, was characterized using electrospray ionization from chloroform. The intact (1:3) complex was observed in the negative-ion mode as a Cl--bound species using Ph4PCl as the source of the charge donor. Collisionally and thermally induced dissociation of the (1:3) complex resulted in the simultaneous loss of all the three RCA units, indicating a cooperative binding of RCA units in the (1:3) complex. These results suggest that the attachment of small, organic-soluble ions may be a useful technique for mass spectrometric characterization of neutral supramolecular complexes that are stable or soluble only in non-polar organic solvents.

    Micellar electrokinetic chromatography in coated capillaries: Determination of micelle-aqueous partition coefficients (1995)

    Topics: Chemistry and Pharmacology
    Notes: A micellar electrokinetic chromatography method is presented for the determination of the partition coefficient for the distribution of nonpolar and moderately polar solutes between the micelle and the aqueous phases in aqueous micellar solutions. In comparison with the literature the method is, theoretically and experimentally, the most straightforward for this application. An equation is derived for the determination of the partition coefficient in a coated fused silica capillary, with neglible electroosmotic flow, from simple measurements of the migration times of solutes and a marker for micelle migration. The advantages and limitations of this method are discussed. The method is tested by using sodium dodecylsulfate (SDS) surfactant and naphthalene, benzene, toluene, and phenol solutes. Micellar electrokinetic chromatography in coated columns isideally suited for the separation of hydrophobic solutes in aqueous samples.

    Complete PCB congener distributions for 17 aroclor mixtures determined by 3 HRGC systems optimized for comprehensive, quantitative, congener-specific analysis (1996)

    Notes: Three HRGC systems (1: 30m DB-XLB capillary with MS-SIM detection; 2: 60m DB-XLB capillary with full-scan, ion-trap MS detection; and 3: Parallel dual-column DB-17 and series-coupled HP5/HT5 with ECD detection) were used to completely characterize multiple lots of 8 different-numbered Aroclor mixtures by quantitative calibration against 9 solutions containing primary standards of all 209 PCB congeners. Despite lower absolute sensitivity and more Aroclor congener coelutions than the dual-column ECD system, the MS systems enabled measurement of more congeners per Aroclor since their greater linear response range did not require dilution of samples and standards. Pairs of different lots of Aroclors 1248 and 1254 displayed markedly different proportions of congeners, and the 1254 pair displayed strong differences in the extent of ortho-chlorine substitution. The tables of congener weight percent distributions among Aroclors are more comprehensive and quantitatively precise than those of prior publications. However, the limitations of single-level calibration precluded measurement of all congeners to the ±10% accuracy desirable for establishing these Aroclors as secondary standards for comprehensive, quantitative congener-specific PCB analysis.
