ABSTRACT
Obturator artery is frequently a branch of anterior division of the internal iliac artery. It has drawn attention of pelvic surgeons, anatomists and radiologists because of the high frequency of variations in its course and origin. The obturator vein is usually described as a tributary of the internal iliac vein. During routine dissection classes to undergraduate medical students we have observed obturator artery arising from external iliac artery, obturator vein draining into external iliac vein, communicating vein between obturator vein and external iliac vein and inferior epigastric artery arising from the obturator artery. The anomalous obturator vessels and inferior epigastric artery in the present case may be in a dangerous situation in pelvic surgeries that require dissection or suturing along the pelvic rim. Developmental reasons and clinical significances of the variations are discussed.
A artéria obturatória é muitas vezes um ramo da divisão anterior da artéria ilíaca interna. Ela tem chamado atenção de cirurgiões pélvicos, anatomistas e radiologistas devido à alta freqüência de variações em seu trajeto e origem. A veia obturatória é geralmente descrita como uma tributária de veia ilíaca interna. Durante aulas de dissecação para estudantes de medicina, observamos a artéria obturatória surgindo a partir da artéria ilíaca externa, veia obturatória drenando para a veia ilíaca externa, veia comunicante entre a veia obturatória e a veia ilíaca externa e artéria epigástrica inferior surgindo a partir da artéria obturatória. Os vasos obturatórios anômalos e a artéria epigástrica inferior no presente caso podem se encontrar em situação perigosa em cirurgias pélvicas que exigem dissecação ou suturas ao longo da borda pélvica. Discutem-se as causas de desenvolvimento e a significância clínica das variações.

Molecular biology has become one of the most fascinating fields of biology in recent years. Molecular methods have been applied in various fields of biology including Medical/Health Science. In this paper, light has been shed on the application of different molecular methods (DNA analysis) in the field of Forensic Medicine.

Nine female pregnant rats were treated with single dose (30mg/kg) of 5-fluorouracil on 12th day of gestation. Gross defects in developing brain of rat fetuses were observed. 5-Fluorouracil is an antineoplastic drug, which has not been adequately studied. 5-FU induced about 5% mortality with significant reduction in body weight and various dimensions of the developing brain (p<0.001). Macroscopic findings of the developing brain revealed microcephaly, regression or absence of olfactory lobe and obliteration of the various fissures on the dorsal and ventral surfaces of the brain. Neuroembryopathic effects of 5-FU is more marked when given in late phase of gestation. So, it is advisable that the drug should be avoided during this period of pregnancy.
