Morphological changes of the ovary and oviduct from birth until sexual maturation were monitored in 35 female quails. The birds were randomly selected from a flock reared at the quail farm of the Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos. Five quails were weighed and then slaughtered every week starting at one week of age. The ovaries were measured in situ, removed and processed for histological evaluation. Mean body weights and ovary length were 40, 68, 108, 132, 138, 171, and 154 g; and 6.9, 8.8, 11.6, 12.0, 11.8, 13.3, and 13.3 mm for the 1st, 2nd, 3rd, 4th, 5th , 6 th, and 7th week of age. Sexual maturity started at week 6. Histological images of growing and mature follicles coincided with macroscopic observations.

La impulsividad representa un factor importante en la adicción a las drogas en el Perú, por ello, la siguiente investigación se centró en conocer las características de la relación de la impulsividad con la adicción a las drogas, bajo el análisis de la literatura. Se consultaron bases de datos que concentraran investigaciones empíricas, no experimentales, de diseño transversal. La muestra estuvo constituida por siete artículos científicos que analizaron la correlación de las variables. Los resultados evidencian una correlación positiva, con la mayoría de los artículos señalando esa correlación. No obstante, hubo una investigación que encontró una correlación negativa entre ambas variables, lo cual se debe a que la impulsividad fue concebida desde la teoría de la regulación emocional.
