ABSTRACT
We studied the dependence of water exchange in various human tissues (skin, Achilles tendon, various types of hyaline cartilage, muscle, and muscle fascia) on the content of collagen and proteoglycans. Carbohydrates of the connective tissue do not play the major role in tissue water exchange. Collagen fibers and proteoglycan aggregates probably retain the main part of bound and free water, respectively.

A simple in vitro test system based on the use of peroxide-eliminating oxidoreductases (glutathione reductase, glutathione peroxidase) is described. The system allows detection of antioxidant properties of aqueous extracts from raw medicinal plants. The system was used for testing water extract of Baikalskii-6 tea. Antioxidant and, presumably, adaptogenic activity of this tea was detected. In addition to activation of glutathione reductase and glutathione peroxidase, the preparation inhibits erythrocyte catalase and therefore should not be used for detection of antioxidant activity in in vitro screening tests.
