Clinical and treatment effects on 3H-clonidine and 3H-imipramine binding in elderly depressed patients.

3H-clonidine and 3H-imipramine binding were measured in depressed patients, 55 years and older. There was no significant difference in either 3H-clonidine or 3H-imipramine binding between depressed patients and age- and sex-matched controls. There was no significant correlation between 3H-clonidine or 3H-imipramine binding and severity of depression before treatment. There was a significant negative correlation between the KD of 3H-imipramine binding sites and Hamilton score over seven weeks of antidepressant treatment. There was no significant difference between receptor data of responders and nonresponders to antidepressant treatment.

Uropharmacology: X. Central nervous system stimulants and depressants.

Several drugs that are utilized primarily for their effects on the central nervous system also affect lower urinary tract function. Most of these effects are produced by the action of these drugs on adrenergic and cholinergic receptors or by direct action of lower urinary tract musculature. Central nervous system stimulants and depressants which are known to affect the storage or evacuation role of the lower urinary tract are discussed.

Effect of neuroleptics and tricyclic antidepressants upon d-amphetamine discrimination.

After rats were trained to differentiate between the effects of intraperitqoneal administration of 0.6 mg/kg d-amphetamine and saline, pretreatment with various neuroleptic drugs was observed to significantly inhibit d-amphetamine discrimination. Thus, trifluoperazine, haloperidol, fluphenazine, chlorpromazine and thioridazine, but not clozapine, decreased d-amphetamine-induced control of discriminative performance. The ED50s of the effective neuroleptics for this inhibition were similar to those reported for antagonism of amphetamine-induced stereotypic behavior in the rat and the slopes of the dose-response curves were parallel indicating a common site and mechanism of action, presumably blockade of postsynaptic dopaminergic receptors. In contrast, pretreatment with the tricyclic antidepressant agents, imipramine, nortryptiline and desipramine had no significant effect on the discrimination of a dose of d-amphetamine which produced a low degree of discriminative control. The results are viewed in relation to the "dopamine hypothesis" of schizophrenia and affective disorders and the use of this animal behavioral method for determining brain dopamine interactions is discussed.

Coping and marital support as correlates of tinnitus disability.

Although there is increasing awareness that depression can add significantly to the disability associated with chronic medical illness, it is not clear whether all of the impact of psychosocial factors upon medical disability are mediated by or moderated by depression. It has not been determined whether treating depression alone is an adequate strategy for addressing psychosocial magnification of medical disability. We analyzed data collected at initiation of a treatment trial from 92 subjects with chronic severe tinnitus to assess the role of coping, and 49 subject-spouse pairs to assess the role of marital interaction in tinnitus-related role dysfunction. Three multiple regression models were developed. After accounting for gender, tinnitus loudness, and depressive severity among the 92 subjects, greater role dysfunction was associated appraisal of tinnitus as salient, and less role dysfunction with coping through avoidance or seeking social support. Marital interaction was assessed from patient and spouse perspectives. In the patient-rated set, less marital cohesion was associated with greater tinnitus-related role dysfunction. In the spouse-rated set, more punishing responses to subject illness behavior were associated with greater tinnitus-related role dysfunction. In each case the disabling effect was greater in the face of high levels of subject depression. This study provides evidence for the oft-stated analogy between chronic tinnitus and chronic pain, and provides justification for a similar multimodal treatment strategy. Reducing depression is an important means to reduce medical disability but should be supplemented by clinical attention to appraisal of the illness, modes of coping with the illness, and spousal response to the illness.

Treatment of adolescents with major depression: implications of the DST and the melancholic clinical subtype.

Of 38 adolescents hospitalized with major depression, 47% of those receiving psychosocial treatment alone responded. Of the non-responders then treated with combined tricyclic antidepressants and psychosocial treatment, 92% responded. The melancholic subtype and dexamethasone suppression test non-suppression were associated with failure to respond to psychosocial treatment alone. Implications for controlled studies are discussed.

Plasma tryptophan to large neutral amino acid ratios in depressed and normal subjects.

The ratios of total and free plasma tryptophan to the sum of five large neutral amino acids (LNAAs) were found to be significantly lower in a group of 16 depressed inpatients compared to nine normal subjects after oral loading with L-tryptophan. The group differences in these ratios were significant before, and 2 weeks after starting treatment with a tricyclic antidepressant. Plasma tryptophan ratios and severity of depression were not significantly correlated.

REM sleep, naps, and depression.

Continued interest in rapid eye movement (REM) sleep abnormalities in depression stimulated comparative studies on daytime naps versus nighttime sleep. In a group of 15 depressed patients, REM latencies in morning and afternoon naps were similar to the shortened REM onset at night. Although REM latency did not vary across the three times, the propensity for REM sleep appeared to be greater in the morning nap than in the afternoon nap and the early portion of nocturnal sleep. Finally, the data suggest that responders to tricyclic treatment tend to be poor sleepers during daytime naps.
