Inhibition of calcification in embryonic bone rudiments was studied in the presence of several tetracyclines at three different concentrations. Different criteria for calcification and different concentrations of tetracyclines yielded parallel results and showed significant differences in the inhibitory action of the various compounds. The clear-cut results indicate that the test-system that wa...

change in the crescent-shaped cap of the distal phalanx are the two main candidate pathogenetic mechanisms that have been proposed.[6] Exposure to teratogens, especially antiepileptic drugs in utero, in mothers with epoxide hydrolase deficiency is another supposed cause of COIF. This probably could explain our patient’s predicament, as her mother had consumed an abortifacient when our patient w...

Environmental teratogenic factors (e.g. alcohol) are preventable. We focus our analysis on human teratogenic drugs which are not used frequently during pregnancy. The previous human teratogenic studies had serious methodological problems, e.g. the first trimester concept is outdated because environmental teratogens cannot induce congenital abnormalities in the first month of gestation. In addit...

A single stillborn female with craniofacial, abdominal, and central nervous system malformations was exposed to reserpine during the first six weeks of gestation. Parallels between the malformations present in this infant and those induced in rats through exposure to reserpine at analogous periods of gestation suggest that reserpine may pose specific risks for malformations in some pregnancies.

Normal development of the human kidney and lower urinary tract is a highly complex process that not uncommonly goes wrong. Furthermore, congenital malformations of these structures, involving absent, immature, or poorly-grown organs, account for most young children with long-term kidney failure who require dialysis and transplantation. Evidence is emerging that some of these individuals have mu...
