ABSTRACT
The Positive and Negative Syndrome Scale or PANSS is a standardized instrument for the measurement of positive and negative symptoms of schizophrenia. The PANSS was widely accepted by researchers and was translated into many languages. It is now translated into Thai, the PANSS-T. The PANSS-T was carefully assessed for its reliability and criterion validity in relation to the PANSS in Thai schizophrenic patients. The results were satisfactory. The PANSS-T can now be used by Thai researchers in clinical studies of schizophrenia that involve the measurement of positive and negative symptoms.

Preliminary studies for peripheral blood leukocytes and lymphocyte subsets were done in smokers and non-smokers. There were 20 smokers (smoked more than 10 cigarettes per day) for more than a year and 20 non-smokers (smoked less than 20 cigarettes/20 years). Ages of smokers and non-smokers were respectively 21-57, and 18-55 years. Cigarette smoking was associated with a statistically significant increase in the number of neutrophils, activated lymphocytes, CD25 and CD19; but a statistical decrease in the percentage of CD7 and CD3.
