Abstract:
Male Hartley guinea pigs (480-610 g; n=5) were treated intratracheally with saline, cadmium (Cd, 0.3 mg) as cadmium chloride, selenium (Se, 0.3 or 0.06 mg) as sodium selenite or Se (0.06 mg) and Cd (0.3 mg). After 24 hours, lungs were collected and analyzed for prostaglandin (PGE2), thromboxane (TXB2) and leukotriene (LTC4) levels. Results indicated that, 0.3 mg Se and 0.06 mg Se in combination with 0.3 mg Cd increased PGE2 significantly. Selenium and Cd alone or in combination, decreased LTC4 and TXB2 significantly.
