title: Modulatory effect of Areca nut on the action of mace (Myristica fragrans, Houtt) on the hepatic detoxification system in mice.
abstract: The present paper reports the modifying potential of areca nut (Areca catechu), an ingredient of the habitual masticatory betel quid, on the induction of the hepatic detoxification system in mice by mace (the aril of nutmeg, Myristica fragrans) a known chemopreventor of chemically induced carcinogenesis. The modulatory effect of areca nut was assessed by determining the levels of enzymes of the hepatic detoxification system, such as glutathione S-transferase (GST), cytochrome b5 and cytochrome P-450, and the content of acid-soluble sulphhydryl (-SH). Mice were fed either control diet or diet containing 0.25, 0.5 or 1% areca nut for 45 days. During the last 10 days the diet was supplemented with 0.5 or 1% mace. At 0.5 and 1% in the diet, areca nut decreased mace-induced increases in hepatic GST and -SH levels and elevated further increases in the levels of cytochrome b5 and cytochrome P-450.
