Résumé

El quiste de colédoco consiste en la dilatación quística de la vía biliar intrahepática o extrahepática. Según la teoría mas aceptada, es causado por una anormalidad de la unión biliopancreática. Sus complicaciones más importantes son colangiocarcinoma, litiasis biliar, y pancreatitis, y su terapia es la resección quirúrgica. Sólo 20 por ciento a 30 por ciento de los casos se diagnostican en la vida adulta. Se reportan dos casos de quiste de colédoco en pacientes femeninas adultas, una de ellas al final de la gestación, y la otra puérpera. El diagnóstico de quiste de colédoco en la gestación y puerperio es un evento inusual que tiene consideraciones propias en cuanto a presentación y manejo.


A choledochal cyst is a cystic dilation of the intrahepatic or extrahepatic biliary tract. According to the most accepted theory, it is caused by an anomalous pancreatobiliary junction. The most important complications are cholangiocarcinoma, lithiasis, andpancreatitis. Current therapy is surgical resection. Only 20 per cent to 30 per cent of cases are diagnosed in adult life. Two cases of choledocal cysts are reported in female adult patients, one of them in late pregnancy and the other in puerperium. Diagnosis of choledochal cyst in pregnancy and puerperium is an uncommon event, entailing particular considerations regarding symptoms and treatment.

Résumé

In vitro regeneration of shoots from leaf explants of the Paradise tree (Melia azedarach L.) was studied. Three different portions (proximal portion, distal portion and rachis of the leaflets) of three developmental stages (folded, young still expanding and completely expanded) of leaves of 10-15 year old plants of seven genotypes were cultured on Murashige and Skoog (1962) medium (MS) supplemented with 1 mg x l(-1) benzylaminopurine (BAP) + 0.1 mg x l(-1) kinetin (KIN) + 3 mg x l(-1) adenine sulphate (ADS). The rachis of the leaflets of the completely expanded leaves was found to be the most responsive tissue, in most of the genotypes employed. Shoot regeneration occurred in leaf explants of all the genotypes tested. The best genotype for shoot regeneration was clone 4. Rooting was induced on MS medium supplemented with 2.5 mg x l(-1) 3-indolebutyric acid, IBA, (4 days) followed by subculture on MS lacking growth regulators (26 days). Complete plants were transferred to soil.
