| | Human Teratogens: A critical evaluation |
 | | Teratogenic specificity also applies to species, for example, aspirin and corticosteroids have been found to be teratogenic in mice and rats but appear to be safe in humans. |  | | Although major new teratogenic drugs in humans have been predicted from animal studies, there are problems in extrapolating animal data to humans. |  | | Thalidomide, on the other hand, was not shown to be teratogenic in rats, a tragic fact that resulted in significant human morbidity. |

 | | A developing baby's reaction to a teratogen is thought to be influenced by her or his genetic makeup. |  | | The most sensitive period is said to be the first three weeks of embryonic life, when the major body organs and systems begin to develop; teratogenic exposures during the first three weeks sometimes result in miscarriage. |  | | Exposure to cancer-causing agents (carcinogens) can affect the developing baby at any stage of intrauterine life. |

| | TERATOGENS |
 | | Cases of phocomelia in the early 1960's in Germany and Australia led to the identification of thalidomide as a human teratogen. |  | | The public awareness of hazardous agents in the home and the workplace, and awareness of the teratogenic potential of drugs or medications during pregnancy has led to the establishment of teratogen information services in most states or regions of the country. |  | | This may be because there has been an increase in the number of synthetic chemical compounds in use or possibly the clinical recognition of subtle malformations as teratogenic effects. |

 | | Moffet argues that "pregnancy sickness" (a.k.a., "morning sickness") is not a sickness at all, but an adaptive response to avoid potential teratogens. |  | | Similarly, industrial teratogens (methylmercury, thalidomide, etc.) are artificial compounds not usually found in nature and have none of the "warning signals" associated with naturally occuring toxins. |  | | The mechanism for producing such an adaptive response appears to be correlated through the hormones. |

 | | One such teratogen assay method is based on the ability of primate derived cell cultures to support infection by poxvirus. |  | | The major limitation of model systems is that they oversimplify the complexity of a multi-cellular organism. |  | | Thus, any teratogen that acts by inhibiting cell proliferation or by disturbing cell metabolism in subtle ways that may not be overtly or immediately cytotoxic will cause a quantitative or qualitative change in progeny virions. |

 | | The timing of foetal exposure to a teratogen is one of the major determinants of what effects the teratogen will have on prenatal development. |  | | A teratogen is any medication, chemical, infectious disease, or environmental agent that might interfere with the normal development of a foetus and result in the loss of a pregnancy, a birth defect, or a pregnancy complication. |  | | Some examples are listed, but there are other teratogens which are not on this list. |

| | #322 (01/27/93): America Learns About Teratogens |
 | | Although the systematic medical literature on occupational health reaches back to the year 1700, concern about teratogens and mutagens is almost brand new. |  | | Naturally, management had some appreciation of acute toxic effects from chemicals (sick workers can't be productive, and they might sue), but the only long-term consequence that anyone talked about was cancer. |  | | Up until this time, some Americans had been concerned about cancer from chemicals, but thalidomide brought home the dangers of teratogens and mutagens. |
