[Lipoprotein lipase activity in healthy subjects and patients with metabolic disorders].
The activity of the post-heparin-lipase as well as of the cholesterol and triglyceride levels of test persons with normal weight and obese test persons of different age groups was established: 1. In normal persons (males and females) in mature age (30-45 years) a decrease of the enzyme activity takes place which is connected with an increase of the triglyceride content. Above all in older females a repeated increase of the post-heparin-lipase activity was observed, which positively correlates with the triglyceride level. While the decreases of the enzyme activity in mature age may be connected with processes of ageing, a repeated increase of the enzyme activity in older persons is perhaps induced by the increase of the triglyceride level. 2. Obese persons show higher enzyme activities in all age groups examined. Also in obese persons in mature age a decrease of the activity of post-heparin-lipase is to be established. The ageing development of the enzyme activity of the post-heparin-lipase is similar to that of normal persons, takes place, however, at a higher level. 3. The cholesterol and triglyceride levels of the obese persons examined were on an average higher than those of normal persons of the same age group. A dependence of age of these parameters was not observed in the adipose patients.
