Introduction to the special section on the contribution of psychotherapy and pharmacotherapy research to national mental health care.

This special section represents a coordinated publication of the Journal of Consulting and Clinical Psychology and the Archives of General Psychiatry. These 2 journals have typically focused on somewhat different areas of research and have been read by different audiences. In an effort to achieve cross-fertilization of the disciplines of psychiatry and clinical psychology, this coordinated publication provides a current view of research both in psychopharmacology and psychotherapy as applied to major depression, anxiety disorders, alcohol abuse, and drug abuse. To further the aims of informing the diverse readership in areas to which they are often not exposed in the separate journals, the Journal of Consulting and Clinical Psychology is publishing in this section, articles that address biomedical and psychopharmacological research, and the Archives of General Psychiatry is publishing a coordinated set of articles on psychotherapy and behavior therapy. Collectively, the series contained in these 2 journals is designed both to foster knowledge and to enhance communication among psychiatrists and psychologists.

Psychiatry.

In 1994, the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) was published. Two studies suggested that the prevalence of psychiatric disorders may have been underestimated. A susceptibility gene for manic-depressive illness has been reported.

Amplified RNA synthesized from limited quantities of heterogeneous cDNA.

The heterogeneity of neural gene expression and the spatially limited expression of many low-abundance messenger RNAs in the brain has made cloning and analysis of such messages difficult. To generate amounts of nucleic acids sufficient for use in standard cloning strategies, we have devised a method for producing amplified heterogeneous populations of RNA from limited quantities of cDNA. Whole cerebellar RNA was primed with a synthetic oligonucleotide containing the T7 RNA polymerase promoter sequence 5' to a polythymidylate region. After second-strand cDNA synthesis, T7 RNA polymerase was used to generate amplified antisense RNA (aRNA). Up to 80-fold molar amplification has been achieved from nanogram quantities of cDNA. The amplified material is similar in size distribution to the parent cDNA and shows sequence heterogeneity as assessed by Southern and Northern blot analysis. Specific messages for moderate-abundance mRNAs for actin and guanine nucleotide-binding protein (G-protein) alpha subunits have been detected in the amplified material. By using in situ transcription to generate cDNA, sequences for cyclophilin have been detected in aRNA derived from single cerebellar tissue sections. cDNA derived from a single cerebellar Purkinje cell also has been amplified and yields material that hybridizes to cognate whole RNA and mRNA but not to Escherichia coli RNA.

Influence of maternal proximity on behavioral and physiological responses to separation in infant rhesus monkeys (Macaca mulatta).

The effects of maternal proximity on the behavioral and physiological responses of infant rhesus macaques during 4 days of total or adjacent separations from the mother were studied. The 6 infants tested showed behavioral responses that differentiated the two separation conditions. Major differences were found in the quantity and quality of vocalizations, the occurrence of cage-biting and cage-shaking behavior, object exploration, and hunched and freezing postures. In particular, the structure of coo vocalizations clearly discriminated between the presence or the absence of the mother during separation. Cerebrospinal fluid (CSF) concentrations of dopamine and serotonin metabolites did not discriminate between the two separation conditions but showed a transient elevation at 24 hr after separation and were not different from baseline by 96 hr after separation. In contrast, both the plasma cortisol and the CSF norepinephrine metabolite responses tended to be greater and to persist for a longer period of time when infants were totally isolated. The results are discussed within the context of attachment and coping theories.

CSF phenylacetic acid and hostility in paranoid schizophrenia.

Lumbar cerebrospinal fluid concentrations of phenylacetic acid were significantly elevated in paranoid vs. nonparanoid schizophrenics. Further, phenylacetic acid concentrations were correlated with hostility. These results are consistent with the hypothesis that phenylethylamine, the proposed precursor of phenylacetic acid, plays a role in schizophrenia.
