The influence of active components of Eleutherococcus senticosus on cellular defence and physical fitness in man.

The influence of active components of Eleutherococcus senticosus, contained in Taiga Wurzel preparation, were studied on cellular defence and physical fitness in man. 50 healthy volunteers of both sexes were selected, and basic clinical examination and laboratory tests were performed in all subjects. All were randomly subdivided into two study groups: group A with 35 subjects receiving Taiga Wurzel and group B with 15 subjects receiving Echinacea.

The influence of exogenous antioxidants and physical exercise on some parameters associated with production and removal of free radicals.

Metabolic processes generate chemically active forms of oxygen, among which a prominent role is played by the superoxide ion. Cells are equipped with defence systems against the effects of superoxide radicals, superoxide dismutase is the most important one. The organism depends on the delivery of exogenous antioxidants, like selenium, vitamins E and C.

Effect of lecithin on the development of experimental atherosclerosis in rabbits.

Thirty male mongrel rabbits were divided into 3 equal groups: (1) controls, (2) animals receiving a high-fat diet (HFD) containing cholesterol and coconut oil, and (3) HFD + lecithin. The experiment lasted 12 weeks. In animals receiving a HFD (group II) the QRS interval (ECG) was significantly prolonged, and the concentration of lipid fractions (except for HDL-cholesterol) and malondialdehyde (MDA) in the blood was markedly elevated.

Comparative pharmacokinetics and bioavailability of flavonoid glycosides of Ginkgo biloba after a single oral administration of three formulations to healthy volunteers.

Eighteen healthy volunteers received three different formulations of Ginkgo biloba: capsules (A) and drops (B) (delivered by Agon Pharma), and tablets (C) (Tebonin-Dr. W. Schwabe) in equal an quantity, orally as a single dose, at an interval of at least five days.
