Abstract

The fetotoxic potential of betel nuts was investigated in Swiss albino mice. Total aqueous extracts of ripe betel nuts of unprocessed and processed varieties were administerd to pregnant animals at dose levels of 1, 3 and 5 mg/day/mouse (27 ± 1 g body wt) through days 6–15 of gestation. The dams were sacrificed prior to term and the fetuses were examined for morphological, visceral and skeletal anomalies. The treatments resulted in increased resorptions as well as dead fetuses. Fetal weight was adversely affected as indicated by the dose related reduction in average body weight of live fetuses. No major morphological, visceral and skeletal defects, apart from hematomas, curved tails and a few incidences of rib anomalies, were observed. There was, however, a dose-related decrease in the number of fetuses possessing ossified coccygeal vertebrae while an increase in the number of fetuses with unossified 5gh metacarpals. This indicated a delay in skeletal maturity, particularly in those fetuses exposed prenatally to the betel nut extract of the unprocessed variety.

    Especially, more and more studies on the safety of herbal medicines during pregnancy have been executed all over the world [3,4]. Up to now, many herbs, such as realgar [5], euphorbia [6], betelnut [7], podophyllum [8], and aconite [9], have been shown to be embryotoxic. Curcuma zedoaria, a herb widely distributed in subtropical region, has been used to treat various diseases.

    The mechanisms governing areca nut-mediated birth weight reduction are mostly unclear. It has been suggested that embryotoxicity of areca nuts in mice may result from a delay in skeletal maturity (Sinha and Rao, 1985a). Animal studies indicate that impaired muscle development also contributes heavily to low birth weight (Fahey et al., 2005; Rehfeldt and Kuhn, 2006).

    In conclusion, our preliminary results suggest that inhibition of blastocyst growth by arecoline may be responsible for the reduced pregnancy associated with arecoline ingestion. Sinha and Rao have determined that aqueous extracts of ripe betel nuts of unprocessed and processed varieties were administered to pregnant Swiss albino mice at different dose levels and showed to be fetotoxic (Sinha and Rao, 1985a). These studies resulted in increased resorption, dead fetuses and an adversely affected fetal weight.

  • Altered BRCA1 and BRCA2 responses and mutation of BRCA1 gene in mice exposed chronically and transgenerationally to aqueous extract of betel nut (AEBN)

    2011, Environmental Toxicology and Pharmacology
    Citation Excerpt :

    Since AEBN is a general carcinogen capable of affecting various tissues, it is likely that exposure of P generation parental mice caused alterations in the Brca1 and Brca2 proteins of their germ cells. The previously reported genotoxic potential of arecoline in mouse germ cells (Sinha and Rao, 1985a,b) supports this contention. Thus, AEBN induced decline in Brca1 and Brca2 protiens would have been initiated in P generation during the 6 weeks of exposure prior to mating (Wary and Sharan, 1988; Choudhury and Sharan, 2009).
