Ginkgo biloba is the oldest tree on the planet. Its healing characteristics have been weel known for more than 3000 years. The aim of this investigation to establish the influence of Ginkgo biloba extract (Egb 761 Tanakan) on bioelectric activity of brain in humans. 30 subjects aged from 52 to 56 years were included in study. The bioelectric activity (EEG) was registrated before and after three month therapy with Ginkgo biloba extract. The obtained results showed that summary bioelectric activity speeds up. Frequency of alpha rhytms increases significantly, number of desinchrayitation desreases, decreases number of non specific activity 

Menopause may influence negatively the cardiovascular system of women, especially that of smokers. The aim of
our study was to compare lipid levels and left ventricular function in postmenopausal women smokers and non-smokers
during 12 months of oral estrogen replacement therapy. The study group included healthy postmenopausal women, 30
smokers and 32 non-smokers. Before and in 6 month intervals the following parameters were followed: total cholesterol,
LDL-, HDL-cholesterol, triglycerides, blood pressure and echocardiographic parameters of systolic and diastolic left
ventricular function. Before therapy non-smokers had higher total and LDL-cholesterol, when compared to smokers. Oral
estrogen replacement therapy significantly decreased levels of total and LDL-cholesterol and increased HDL-cholesterol,
only in non-smokers. No change in lipid levels was observed in smokers. However, women who smoked longer had higher
triglyceride levels after 12 months of oral estrogen replacement therapy. Echocardiography revealed significant improvement of systolic and diastolic left ventricular function in non-smokers, while improvement of only systolic function in
smokers. Our study has shown that 12 months of oral estrogen replacement therapy may not have a protective role on the
cardiovascular system of postmenopausal women smokers
