Cigarette Smokers

This experimental model related to cigarette smokers compared with non-smokers (Hulea et al., 1995). Smokers generally had a higher plasma lipid peroxide concentration (TBAR) but a lower total antioxidant capacity (Table 14.5). This was significant at ages 46-80 (groups C and D). These subjects had smoked at least 12 cigarettes per day for more than 2 years. It was shown in an in vitro study (Mahfouz et al., 1995) that smoking increased the concentration of lipid peroxides. We used the...

Antioxidants from herbs and spices

The consumption of herbs and spices, which is a feature of many dietary practices world-wide, makes a significant contribution to the intake of phytochemicals with biological action (Huang et al., 1994 Plumb et al., 1995). Numerous spices have been shown to exert biological effects by modulating arachidonic acid metabolism and platelet aggregation (Table Table 15.2. Isoflavone content (mg 100 g 1) in traditional and commercial soy items. Adapted from Samman et al. (1996). Table 15.2. Isoflavone...

Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is an obstructive airway disorder characterized by a gradually progressive and irreversible decrease in forced expiratory volume (FEVj) (Siafakas et al., 1995). The condition usually arises due to chronic bronchitis or emphysema and the airflow obstruction may be accompanied by airway hyperreactivity. Asthma is generally differentiated from COPD, although distinguishing the two in a patient who smokes and has allergies can be difficult. This decrease...
