[Serotonin concentration and transport in the blood platelets of ischemic stroke patients and their relatives].

Serotonin levels and transport were studied in patients with ischemic stroke (n = 31), their relatives (n = 50) and clinically healthy subjects (n = 45). A statistically significant difference was found in the absorption of exogenic serotonin in the patients and relatives. It has been shown that if judged by serotonin levels, the distribution curves in the control subjects patients with ischemic stroke and their relatives correspond to a model of the polygenic type of the heredity of the traits studied.
