Teratological Note

Two Teratological Cases

Burnei’s disease: teratological spondylolysis

Teratological spondylolysis is a pathological entity noted for the first time in the specialty literature by Gh. Burnei in "The Spine Journal", in September 25, 2014. This disease was described in a short presentation of the first case treated by the author. The aim of this paper was to expose in a didactic manner the main characteristic aspects of Burnei's disease: embryological, clinical, ima...

Morphological studies in modern teratological investigations.

Despite the variety of modern molecular techniques available, examination of foetal anatomy is still a fundamental part of teratological studies in evaluating the developmental toxicity of xenobiotics or other non-chemical factors. The article presents contemporary methods of embryotoxicity and foetotoxicity assessment. A single alizarin red S and double alcian blue followed by alizarin red S s...

Toxicological, pathological, and teratological studies in animals with cephradine.

Cephradine, a semisynthetic cephalosporin antibiotic, has a low order of oral and parenteral toxicity in animals. The oral LD(50) in mice and rats ranged from 5 to >8 g/kg, and the intraperitoneal LD(50) values in mice and rats were 0.7 to 1.5 g/kg and 4.0 g/kg, respectively. The intravenous LD(50) in mice ranged from 3.0 to 3.8 g/kg. In anesthetized dogs, intravenous doses of cephradine (40 an...

Teratological research using in vitro systems. IV. Cells in culture.

Several in vitro cellular systems designed to screen agents for teratogenic potential are described in this report. These assays were selected from a review of literature published through the spring of 1986 that generated over 100 references on teratological research using cell-based systems. Some of the assays have a broader application than others, but most require confirmation by one or mor...
