    Notizen: Abstract  Although there is a need for systematic research on the psychosocial issues faced by lung cancer patients, there have been few studies in this area. The objective of the present study was to investigate potential predictors of psychological distress among ambulatory lung cancer patients. The variables examined included the patients' characteristics, coping responses, and social support factors. Lung cancer patients completed the Profile of Mood States (POMS) and the Mental Adjustment to Cancer scale (MAC scale), and information pertaining to demographic variables and social support factors was obtained from them at a structured interview. Evaluable data were obtained from 87 patients. The results of multiple regression analysis indicated that female gender, living alone, no children in the role of confidant, nurses as confidants, and helplessness/hopelessness as a coping style were predictive for psychological distress. Information on patients' demographic variables and psychosocial correlates of psychological distress may later be useful in developing interventions to facilitate their adjustment to lung cancer.

    Notizen: Summary Serotonin (5-HT)-2 receptor-mediated cGMP generation was investigated in comparison with calcium (Ca2+) mobilization in C6 glioma cells. 5-HT enhanced cGMP generation, and risperidone and ketanserin potently blocked the response. These results indicate that 5-HT-2 receptors are responsible for the cGMP generation. 5-HT-induced cGMP production was completely abolished by BAPTA, an intracellular Ca2+ chelating agent, or N g -monomethyl-L-arginine (NMMA), a nitric oxide synthase (NOS) inhibitor, suggesting that 5-HT-induced cGMP generation was through nitric oxide (NO)-dependent pathway. 5-HT (10 μM)-elicited Ca2+ mobilization and cGMP generation were reduced to 40 and 15 % after pretreatment with 10 μM 5-HT for 4 hours. NMMA did not modify 5-HT-induced desensitization of either Ca2+ mobilization or cGMP generation, suggesting that NO pathway is independent of the desensitization. The present study has demonstrated the nature of 5-HT-2 receptormediated cGMP generation in C6 glioma cells.
