RESUMO
La achicoria o chicoria es una planta medicinal cuya infusión es frecuentemente usada como un compuesto mucolítico en neonatos y lactantes. Se reportan doce casos con probable intoxicación por achicoria (Cichorium intybus), en los cuales fueron comunes signos clínicos opioide-similares como depresión del sistema nervioso central y respiratoria, pupilas puntiformes y estreñimiento. El tratamiento consistió en descontaminación interna, oxígeno por mascarilla, fluidoterapia IV y en seis casos con severa depresión respiratoria se administró naloxona IV. En todos los pacientes se observó una evolución clínica satisfactoria y fueron egresados uno o dos días después.
Chicory is a medicinal herb which infusion is usually used as a mucoactive compound in neonates and infants. Twelve cases with probable chicory poisoning (Cichorium intybus) are reported, in which were common opioid-like clinical signs as central nervous system and respiratory depression, pin-point pupils and constipation. Treatment consisted of internal decontamination, oxygen by mask, fluids IV and in six cases with respiratory depression severe naloxona IV was administered. In all patients a satisfactory clinical course was observed and they were discharged one or two day after.

SUMMARY Endive, cv. Crespa, was seeded in May 25, June 18, July 31 and August 20, in 1987, and in May 06, June 30, July 26 and August 18, in 1988, to determine the influence of seeding dates in plant development, seed yield and quality. It was utilized the block randomized experimental design, with four replications and spacing of 0,60m and 0,20m between rows and plants, respectively. The dates of plant emergence, bolting, flowering and maturity were registered and the rates of germination and vigor were determined. It was also determined the base temperature and the number of day-degrees accumulated in each development stage. The results showed shorter plant cicle and lower plant development and seed yield under long days and high temperatures. The better seeding dates occur in May and June, while seed germination and vigor are not influenced by seeding dates.
RESUMO Foram realizadas semeaduras de chicória, cv. Crespa, nas datas de 25/05, 18/06, 31/07 e 20/08, em 1987 e em 06/05, 30/06, 26/07 e 18/08, em 1988. Utilizou-se o delineamento experimental de blocos casualizados, com quatro repetições e espaçamento de 0,60m e 0,20m entre fileiras e plantas, respectivamente. Determinaram-se, para cada época, as datas de emergência, pendoamento, floração e maturação das plantas e o rendimento e qualidade das sementes. Também determinou-se a temperatura base de crescimento e a soma térmica para cada um dos subperíodos fenológicos. Os resultados mostraram que as melhores épocas de semeadura ocorrem nos meses de maio e junho, que o fotoperíodo crescente e as temperaturas elevadas aceleram o ciclo, reduzem o crescimento, o desenvolvimento da planta e o rendimento de sementes e que a germinação e o vigor das sementes não apresentam relação com a época de semeadura.
