Extract

Following the work of Dale (1934) and Loewi (1935) on the relationship of choline esterase to the transmission of nervous impulses, a number of studies have been made of the choline esterase activity of the serum in different physiological and pathological conditions. The serum esterase activity varies considerably from one individual to another, but it generally remains very constant in any one individual even over long periods of time; it is believed to be unaffected by changes in diet, exercise, fatigue, or by menstruation. The earlier investigators were unable to correlate the esterase level with any such factor as age, sex, heart rate, blood pressure, weight, or with pathological conditions such as benign or malignant tumours, chronic infections, heart diseases or neurological conditions (v. Verebely, 1936; McGeorge, 1937); they found only a tendency to low esterase activities in acute infections (Hall and Lucas, 1937) and in advanced tuberculosi (Vahlquist, 1935).

In an investigation in which psychopathic patients were included Tod and Jones (1937) and Jones and Stadie (1939) described a number of positive correlations between the serum choline esterase and various clinical conditions. They found a high esterase activity in anxiety states and lowered activity in catatonic stupor, epilepsy, schizophrenia and also in advanced tuberculosis and carcinoma. Antopol et al. (1937, 1938) associated high serum esterase activity with thyrotoxicosis and low activities with liver disease, anaemia and hyperpyrexia. Milhorat (1938), in agreement with Jones and Stadie, attributes the low esterase activities in these conditions to the general debility, but McArdle (1940) concludes that impairment of liver function is the primary cause.

The present work was carried out with the object of obtaining further information as to the relationship between the serum choline esterase activity and anxiety.
