CableQuit was a 6-week, community cable television smoking cessation program, with 13 30-min "live" sessions, each followed by a 30-min "live" telephone call-in support segment. Telecasts were hosted by a public health educator with postdoctoral training in smoking cessation. Five smokers from Austin, Texas, were selected to participate "live" in the studio, while registrants followed step by step at home. A time-series design was utilized to evaluate program effectiveness. Baseline and follow-up data were gathered via mail as well as saliva samples, subsequently tested for cotinine analysis of smoking status. Participants were followed-up at 6 weeks, 6 months, and 12 months. Nonsmokers at 1 year had significantly greater levels of self-efficacy (p < .004) and significantly lower levels of depression (p < .03) than smokers. A 1-year quit rate of 17% exceeded those of previous televised programs (5-15%). Utilization of combined face-to-face smoking cessation techniques with mass media warrants further research.

A 1-year longitudinal study tested the model that the relation between maternal depression and adolescent suicidal symptoms is mediated by family functioning. Participants were 240 children (mean age = 11.86 years) and their mothers; 77% of the mothers had a history of a mood disorder and the remaining 23% were lifetime-free of psychopathology. An adolescent suicide index was created based on suicide items from the child and parent versions of the Children's Depression Inventory, Child Behavior Checklist and Children's Depression Rating Scale, administered at both Time 1 and 2. Family functioning was assessed with the Family Relationship Index completed by mothers and children at Time 1. Results indicated that the relation between maternal depression and adolescent suicide symptoms at Time 2 was mediated by perceived family functioning, controlling for suicide symptoms at Time 1.

A 1-year prospective study of 43 elderly depressed residents (13 men and 30 women) in Nagai City in Japan is described. An initial survey was carried out in 1993 to find depressed residents. The subjects of the survey were 2056 residents of 65 years of age and older. The Japanese version of the Geriatric Depression Scale (GDS) was employed as a screening tool in the first phase of the survey. In the second phase, screened subjects and control subjects were interviewed by psychiatrists using the Structured Interview for DSM-III-R (SCID). The diagnosis of depression was made by the psychiatrists on the basis of the results of the SCID. Forty-three persons were judged to be depressed. At follow-up, 10 were still depressed and 15 were well. Four were demented. Fourteen dropped out due to death, hospitalization, absence from home or refusal. The results showed that approximately half of the elderly depressed persons seemed to recover by the time of the 1-year follow-up. One-year prognosis of dysthymia was the worst. Some types of depression seemed to be a precursor for dementia. The concern is with how the findings may be used as an aid in understanding and planning community mental health services strategies. The results indicate that it is very important to pay close attention to patients with depressive illness who do not meet the criteria for major depression.

Enadoline is a highly selective and potent kappa-opioid receptor agonist. This report describes and compares the activities of enadoline and morphine in a rat model of postoperative pain. A 1 cm incision through the muscle and skin of the plantar surface of the right hind paw induced thermal hyperalgesia as well as static and dynamic allodynia lasting at least 2 days. Postoperative testing was carried out using the plantar test for thermal hyperalgesia, von Frey hairs for static allodynia and light stroking with a cotton bud for dynamic allodynia. A single i.v. dose of enadoline 15 min before surgery dose-dependently (1-100 microg/kg) blocked the development of thermal hyperalgesia as well as static and dynamic allodynia for over 24 h with respective MEDs of < or = 1, 10 and 10 microg/kg. The administration of enadoline (100 microg/kg, i.v.), 1 h after surgery, completely blocked the maintenance of the hyperalgesic and allodynic responses, but its duration of action was much shorter (2 h) than when administered before surgery. Previous studies have shown that administration of morphine (1-6 mg/kg, s.c.) 0.5 h before surgery can prevent the development of thermal hyperalgesia with a MED of < or =1 mg/kg, but it has little effect on static allodynia. In the present study similar administration of morphine (1-3 mg/kg), unlike enadoline, had no effect on the development of dynamic allodynia. Morphine dose-dependently (1-6 mg/kg, s.c.) potentiated isoflurane-induced sleeping time and respiratory depression in the rat. However, whilst enadoline also (1-1000 microg/kg, i.v.) potentiated isoflurane-induced sleeping time, it did not cause respiratory depression. It is suggested that enadoline may possess therapeutic potential as a pre-emptive antihyperalgesic and antiallodynic agent.

We describe the immunocytochemical distribution of adenosine A1 receptors in the rat hippocampus. Adenosine A1 receptor-like immunoreactivity was seen on the cell soma and dendrites of pyramidal cells and the cell soma and proximal part of dendrites of granule cells, but not on glial cells. Developmentally, adenosine A1 receptor-like immunoreactivity was diffuse on postnatal day 7 and increased in intensity in individual cells by day 21. In the CA2/CA3a region, the adult pattern of A1 receptor distribution was established by day 28. In the adult rat hippocampus, rostrocaudal inspection revealed that immunoreactivity in CA2/CA3a was greatest. Confocal microscopy revealed differences in the staining patterns for the adenosine A receptor and synaptophysin, a marker of presynaptic terminals. This result suggests that the adenosine A1 receptor might have postsynaptic physiological functions. Double-labeling of adenosine A1 receptors and anterogradely-labeled fibers from the supramammillary nucleus showed that the fibers from the supramammillary nucleus terminate directly on the cell soma of the A1 receptor-immunopositive neurons in CA2/CA3a and the dentate gyrus. These results indicate that the adenosine A 1 receptor in CA2/CA3a and the dentate gyrus are in a position to regulate hippocampal theta activity and that resultant strong synaptic depression in CA2/CA3a could play a role in regulating the intrinsic signal flow between CA3 and CA1.

The aims of this study were to assess whether dihydrohonokiol, 3'-(2-propenyl)-5-propyl-(1,1'-biphenyl)-2,4'-diol (DHH-B), a potent anxiolytic compound, developed benzodiazepine-like side effects. A 1 mg kg(-1) dose of diazepam, almost equivalent to the minimum dose for the anxiolytic effect, disrupted the traction performance, potentiated hexobarbital-induced sleeping and impaired learning and memory performance. DHH-B, even at a dose of 1 mg kg(-1) (i.e. five times higher than the minimum dose for significant anxiolytic effect) neither developed diazepam-like side effects nor enhanced the side effects of diazepam. Rather, the potentiation by diazepam of hexobarbital-induced sleeping was reduced by 1 mg kg(-1) DHH-B. Furthermore, mice treated with 10 daily administrations of 1 and 5 mg kg(-1) diazepam, but not 0.2-5 mg kg(-1) DHH-B, showed precipitated withdrawal symptoms characterized by hyper-reactivity, tremor and tail-flick reaction when they were challenged with flumazenil (10 mg kg(-1) i.p.). These results suggest that, unlike the benzodiazepine anxiolytic diazepam, DHH-B is less likely to induce motor dysfunction, central depression, amnesia or physical dependence at the effective dose required for the anxiolytic effect.

A 1:1 matched case control study was carried out in 81 cases with temporomandibular joint dysfunction syndrome (TMJDS) who came to a TMJ clinic of a tertiary dental centre for help and 81 controls without TMJDS to investigate the association between psychosocial factors and TMJDS. The results showed that anxiety and depression might be one of the risk factors of TMJDS. Trait anxiety and Eysenck's neuroticism might be the inherent personality factor of anxiety, and the later might be the basis of depression. Life events and social support might be the external factors of TMJDS.

Almost all terrestrial and aquatic assays that are accepted as standardized, or that have been proposed, involve the exposure of confined organisms to toxicants. If avoidance (sensu evasion, displacement) of contaminants occurs in real situations, then bioassays involving forced exposure severely underestimate pernicious effects of contamination. Two main objectives were achieved in this study: To verify the occurrence of avoidance of copper by cladocerans; to determine the association between avoidance and other toxicity endpoints (lethality and feeding depression), and therefore, to ascertain if fully acclimated individuals from a reference field population exhibited a genetically determined avoidance markedly different from those belonging to a historically metal-stressed population. Twelve cloned lineages of the cladoceran Daphnia longispina, collected from two field populations, were selected according to their lethal sensitivity to copper and acclimated to controlled conditions for more than 30 generations. A 1.1-m test chamber with five compartments was built, allowing the establishment of a dissolved toxicant gradient and the free movement of individuals. In the absence of any toxicant, juveniles from each cloned lineage distributed themselves randomly along the test chamber and furthermore, no significant differences were observed between the two replicates, attesting the repeatability of this novel assay. All lineages showed significant avoidance to copper when exposed to a gradient from 3 to 87 microg/L. The most sensitive lineages to lethal levels of copper began avoiding this metal earlier than resistant ones. An intense association was observed between other endpoints and avoidance; furthermore, avoidance was determined to be much more sensitive than lethality. Therefore, avoidance assays should be recommended as a complementary tool in ecological risk assessments and effluent biomonitoring because such assays can provide cost-effective and ecologically relevant information.

The primary endpoints in this study were the remission rates [final Hamilton Rating Scale for Anxiety (HAM-A) total score < or =7] and reduction from baseline in the HAM-A total score in patients with generalized anxiety disorder (GAD) and no associated depression. Patients with GAD (DSM-IV and HAM-A total score >18) were randomly assigned to treatment with venlafaxine XR or placebo for 8 weeks. A 1-week placebo run-in period preceded the double-blind phase. Patients with a >20% drop in their total HAM-A score during the run-in period, were excluded from the double-blind phase. All patients started therapy with 75 mg/day venlafaxine XR or matched placebo. Patients with less than 30% decrease in their HAM-A total score at the end of the second week, doubled their dose. Patients on the 150 mg/day dose underwent a 1-week taper period. Of the 24 patients in the venlafaxine XR group, 62.5% achieved remission versus 9.1% in the placebo group (P=0.0006). The mean decrease from baseline in HAM-A total score was 19.2 points for the venlafaxine XR group and 10.8 points for the placebo group (P<0.001). Eleven placebo-treated patients and seven venlafaxine XR treated patients doubled their dose at the end of the second week of double-blind treatment. No patient interrupted therapy because of side-effects. No changes in systolic or diastolic blood pressure were observed. Venlafaxine XR 75-150 mg/day was well tolerated. The remission rates achieved with venlafaxine 75-150 mg/day in non-depressed GAD patients were high with good tolerability.

Acute zinc poisoning has been observed in dogs following the ingestion of metallic zinc objects. A 1 1/2-y-old female miniature bull terrier exhibiting anorexia, vomiting, depression, fever (39.9 C), icterus and intravascular hemolysis was diagnosed with acute zinc poisoning. Anemia, Heinz body production, azotemia and bilirubinemia were also evident. Abnormal pancreatic, hepatic and renal functions were also apparent. A radio opaque object was observed in the stomach. Based upon an elevated plasma zinc level of 28.6 ppm, a tentative diagnosis of zinc poisoning was made. Following surgical removal of the metallic zinc object, a blood transfusion and fluid therapy were given to restore the normal blood volume. Heparin, Cephazolin and Raniditine were also given, although chelation therapy was not provided. Zinc levels in the plasma declined in a steady fashion (half-life = 7.6 d). Complications, such as disseminated intravascular coagulation, chronic pancreatitis, renal or hepatic failure, were not observed. By 20 d post surgery, only mild elevation of liver enzymes was evident. Measurements of the half-life of zinc may provide a useful indication of prognosis and the success of treatment.
