An alternative method to the Johnson Institute's "Intervention" is presented which, while incorporating many of Johnson's innovations, is, additionally: (a) less confrontative, thereby avoiding the reactivity in clients and family members that such confrontational approaches have tended to evoke; (b) takes into account both the needs of the chemically dependent person as well as the needs of the larger family and network system; and (c) aimed toward enrolling substance abusers in outpatient (as well as inpatient) treatment, thus placing it more in line with managed care priorities. Principles for treatment engagement are presented, accompanied by case examples. The approach is part of a more comprehensive model designed to maximize successful engagement with a minimum amount of professional time and effort.

Prevention of carcinogenesis by tea polyphenols.

Tea, an extract of the leaves of the plant Camellia sinensis, has been considered a medicine and healthful beverage for ages. The beneficial effects of tea are thought to be due to its polyphenolic components. Herein, we discuss the present status of tea as a possible cancer chemopreventive agent, covering basic chemistry and biochemical activity of tea, pharmacokinetics of major tea components, studies in animal and cell lines, epidemiological investigations, and future challenges. Tea is one of the few chemopreventive agents known to have protective effects at different stages of the carcinogenic process. Tea constituents may inhibit this process by modulating signal transduction pathways leading to the inhibition of cell proliferation and transformation and enhancement of apoptosis. These activities may or may not be due to the antioxidative activity of tea polyphenols. The bioavailability and tissue levels of tea polyphenols is a key topic to be studied in order to understand the mechanisms of action of tea and its possible protection against cancer in humans.
