Previous investigators have reported a high prevalence of depressive symptoms in drug-dependent patients. Given the responsiveness of depressive disorders to both psychological and pharmacological treatments, it is desirable to find an economical, efficient screening instrument to detect depressive disorders in this population. In this study, 6
depression
symptom screening scales (Beck
Depression
Inventory, Hamilton
Depression
Scale, Raskin
Depression
Scale, Degree of Illness Rating, Symptom Checklist 90 Overall, and
Depression
Subscale) based on either clinician interview or patient self report, were compared according to their utility in detecting cases of
depression
among 64 applicants for treatment at a substance abuse treatment unit of a community mental health center. The criteria for a case of
depression
were the Research Diagnostic Criteria (RDC) which are specified and operationalized. Cases identified using previously described cutoff scores on the screening scales were compared to rates based on the RDC and sensitivity and specificity were determined. The results showed that: (1) although the sensitivity of the symptom scales was applicable, ranging from 65--94%, the specificity was less impressive, ranging from 39--61%, and (2) the Beck
Depression
Inventory, a 13-item patient self report was the most sensitive and specific and is recommended for screening drug-dependent populations for
depression
.

Thirty-four recent rape victims were assessed for depressive symptomatology using a well-validated self-report instrument in combination with formal psychiatric evaluation. Fifteen subjects were found to be moderately or severely depressed when measured on the self-report questionnaire. A closer examination of these 15 subjects revealed that 8 were suffering from a major depressive disorder. The authors emphasize that all clinicians working with rape victims should be alert to the emergence of
depression
in this population.

Cellular immune responses of patients with histologically confirmed lung carcinoma were assessed in vivo using cutaneous response and in vitro with a microlymphocyte blastogenic transformation (LBT) assay. In addition, correlation of the cutaneous response with the migration inhibitory factor (MIF) assay and LBT response was examined. The results indicated that cutaneous responses seen in patients with cancer of the lung were consistently lower than similar responses in normal controls (p less than 0.001). Similarily, the percentage of positive cutaneous responses seen with patients included in this study was lower than the frequencies reported by others. Stimulation of cells from lung cancer patients by PHA-M was also depressed when compared to similar lymphocytic responses in normal volunteers (p less than 0.001). The correlation between cutaneous response to tuberculin and the in vitro assays was high. The few instances of disparity demonstrate the need to utilize more than one assay in evaluating cellular immune functions. These data would support the work of others that indicate a
depression
of cellular immunity in advanced malignancy.

There have been few reports concerning facilitation and
depression
in sympathetic ganglia9,17,40. In the present investigation, pairs of excitatory postsynaptic potentials (EPSPs) were recorded intracellularly from bullfrog paravertebral sympathetic ganglia for an analysis of the site and mechanism responsible for the phenomena of facilitation and
depression
of ganglionic transmission. The ratio of the amplitude of the second of a
depression
of ganglionic transmission. The ratio of the amplitude of the second of a pair of EPSPs divided by the first was compared to the time interval between each pair of EPSPs divided by the first was compared to the time interval between each pulse. These ratios demonstrated two phases: an earlier phase of facilitation (20-500 msec pulse intervals) and a later phase of
depression
(500 msec-10 sec). Additional parameters-rate of rise of synaptic potentials (dV/dt), synaptic currents (EPSCs), and synaptic conductances (Gtr)-were determined and all confirmed the results obtained with EPSPs. Furthermore, the degree of facilitation or
depression
could be modulated by altering the extracellular concentration of calcium. On the other hand, comparison of the amplitude of pairs of presynaptic terminal spikes did not show any variability over similar stimulus intervals, nor were the amplitudes of miniature EPSPs significantly different before or after an evoked EPSP. Therefore, the processes of facilitation and
depression
of ganglionic transmission occur as a result of normal nerve terminal activity. The processes are occurring simultaneously, such that one or the other may predominate depending upon the interval between pulses, as well as the relative concentration of extracellular calcium.

beta-Adrenoceptor function has been compared in lymphocytes of normal subjects, asthmatic patients taking large doses of beta-adrenergic bronchodilators, and comparable asthmatics treated exclusively with nonadrenergic medication. The effect of prolonged administration of beta-adrenoceptor agonists on receptor function in normal subjects has also been examined. beta-receptor response in each situation was quantitated by changes in levels of cyclic AMP, measured by a protein-binding assay. Dose response curves to isoproterenol (10 nM-0.1 mM) have been constructed for each group. Maximal increase in cyclic AMP in lymphocytes from normal subjects (393.2+/-44.0%) and in asthmatics on nonadrenergic preparations (408.3+/-46.7%) was significantly greater (P less than 0.001) than in asthmatics taking large doses of beta-sympathomimetics (67.5+/-24.2%).
Depression
of the cyclic AMP response appeared to correlate with the degree of exposure to beta-adrenergic agonists but not with the prevailing severity of the patient's asthma. Withdrawal of beta-adrenergic drugs was followed by a reversion of the cyclic AMP response to normal values, which suggests that the
depression
was drug-induced rather than an inherent feature of the disease. This interpretation was confirmed by the finding that prolonged exposure of normal subjects to high doses of a beta-adrenergic agonist caused a marked and significant (p less than 0.001) reduction in the cyclic AMP response, very similar to that seen in asthmatics on large doses of adrenergic bronchodilators. A possible link between drug-induced changes in the cyclic AMP response and the rise in the United Kingdom asthma death rate in the 1960's is discussed.

This research examined the effects of several cyclic nucleotides on in vivo cat soleus nerves and muscles. The reagents were administered by rapid close intra-arterial injection while electrical activity in single motor axons and contractile activity in the whole muscle were monitored. Cyclic N6-2'-O-dibutyryl adenosine 3',5'-monophosphate (dibutyryl cAMP) initiated bursts of action potentials in unstimulated axons. It also caused the occurrence of stimulus bound repetitive potentials in stimulated axons. It caused the muscle to undergo a series of rapid asynchronous contractions and potentiated the strength of stimulus-evoked contractions. Monobutyryl cAMP produced similar responses, but was less potent than dibutyryl cAMP. cAMP produced only a small, transient
depression
of neuromuscular transmission. There was no response to dibutyryl cyclic 3',5' guanosine monophosphate or sodium butyrate. None of these reagents affected denervated muscle. The results suggest that cAMP-like materials that can penetrate nerve membranes cause depolarization of motor nerve terminals, prolongation of the depolarization of the terminal initiated by an action potential and release of transmitter.

Narcotic analgesics and related drugs act as agonists on several receptors that are responsible for their effects on pain perception, mood and feeling state, and respiration, as well as other pharmacologic actions. Naloxone is the first discovered antagonist that is devoid of agonistic activity and appears to be a competitive antagonist at several receptors. The ability of naloxone to displace or prevent the binding of agonistic narcotics is partly responsible for its antagonistic effects. The ability of naloxone to rectify narcotic-depressed homeostats and precipitate abstinence is also related to its antagonistic activity. Certain cautions and principles apply in the use of naloxone in treating narcotic overdose, reversing surgical analgesia, and the treatment of neonates and children. Unapproved uses of naloxine include reversing the psychotomimetic effects of certain agonists-antagonists, terminating narcotic-induced convulsions and coma, reversing non-narcotic
depression
, diagnosing physical dependence, and treating narcotic addicts.

Pressure increases elicited by contractions of the circular muscle of the isolated guinea-pig vas deferens in response to nerve stimulation were recorded. In contrast to longitudinal muscle which contracted in response to 1--50 pulses, circular muscle responded only to longer trains of pulses (10--500) at a frequency of 10 Hz. Atropine (1.4 muM) caused a slight
depression
of responses to 100 shocks. Phentolamine at a concentration of 2.6 muM failed to inhibit the response to stimulation, but a higher concentration (53 muM) caused a definite blockade. Guanethidine (25 muM) strongly reduced the responses. With a stimulus train of 100 pulses no inhibition by prostaglandin E1 (PGE1) (0.028 muM) could be demonstrated; however, at a lower number of shocks (20--50) a clearcut
depression
was observed. The lower the number of pulses the more marked was the
depression
. The observation that PGE1 failed to block the contractions evoked by noradrenaline (59 muM) suggests a presynaptic inhibitory action of the prostaglandin. It is suggested that noradrenaline is the transmitter in both muscle coats of the guinea-pig vas deferens and that the neuroeffector junctions are sensitive to the effect of PGE1.

The authors stress the value of radiological examinations in the diagnosis of interstitial pneumonia in children with immuno-
depression
secondary to chemotherapy and/or radiotherapy. X-rays play a capital role in the early diagnosis of these conditions and may be of vital interest in some cases, in particular pneumocystosis which is curable. The diagnosis is based upon the discovery of minor signs of radiological interstitial syndrome, which in one third of cases is limited to a decrease in lung volume. This syndrome will be associated sooner or later with signs of alveolar involvement. The authors subsequently describe the underlying background, frequency, immune state, the circumstances of diagnosis and features of the aetiological diagnosis.

It was shown that the vital capacity of the mouse kidney tissues quantitatively estimated by the in vitro growth in a plasma-free medium depended upon the condition of the donor organism.
Depression
of the culture growth was noted after the general X-irradiation of the animals, as well as following prolonged starvation and chloric cadmium poisoning. An increased growth of the kidney tissues was observed both in compensatory hypertrophy caused by unilateral nephrectomy and in subcutaneous inflammation.
