Objective: To identify possible differences in the level of externalizing behavior problems among children with and without hearing impairment and determine whether any relationship exists between this type of problem and parenting practices. Methods: The Behavior Assessment System for Children was used to evaluate externalizing variables in a sample of 118 boys and girls divided into two matched groups: 59 with hearing disorders and 59 normal-hearing controls. Results: Significant between-group differences were found in hyperactivity, behavioral problems, and externalizing problems, but not in aggression. Significant differences were also found in various aspects of parenting styles. A model for predicting externalizing behavior problems was constructed, achieving a predicted explained variance of 50%. Conclusion: Significant differences do exist between adaptation levels in children with and without hearing impairment. Parenting style also plays an important role.

Oil from pumpkin seeds has been widely used in the treatment of prostatic hyperplasia. In the present paper, the effect of lipophilic extract of Cucurbita pepo L seeds (ELMSC) was studied in an in vivo model of testosterone propionate -induced experimental prostatic hyperplasia during 15 days. It was found that ELMSC at doses of 400 and 200 mg/kg caused a significant decrease of prostatic growth. Our findings showed that doses of ELMSC over 200 mg/kg inhibits the testosterone-induced prostatic growth in the experimental model of prostatic hyperplasia in rats.

El aceite de semillas de calabaza ha sido ampliamente utilizado en el tratamiento de la hiperplasia prostática. En el presente trabajo se estudió el efecto del extracto lipofílico de semillas de Cucurbita pepo L (ELMSC) en el modelo in vivo de hiperplasia prostática experimental inducida por propionato de testosterona durante 15 días. Se observó que el ELMSC a las dosis de 400 y 200 mg/ kg provocó una disminución significativa del crecimiento prostático. Nuestros resultados indican que el ELMSC a dosis mayores de 200 mg/ Kg inhibe el crecimiento prostático inducido por la testosterona en el modelo experimental de hiperplasia prostática en ratas.

Authors present references review about Coleus (Plecthranthus). We refer isolated compunds and pharmacological activities credited and corroborated for some species of gendre. We in form on Plecthranthus amboinicus (Lour.) Spreng, knowed in our country as French origan and traditionally used in catarrhal infections, its cultivation and harvesting, chemical components, popular uses and preclinical studies performed. To date, results obtained allow us to predict a wide utilization of this species in development of Herbal Drugs, prescribed in catarrhal infections and in cases of epilepsy. We used Medline database (1966/1998), NAPRALERT (1995), International Pharmaceutical Abstracts (1970/1993), and Chemical Abstracts (1998).

Se presenta una revisión bibliográfica acerca del género Coleus (Plecthranthus). Se hace referencia a los compuestos aislados y actividades farmacológicas atribuidas y corroboradas para algunas especies del género. Sobre Plecthranthus amboinicus (Lour.) Spreng, conocida en Cuba como Orégano francés y empleado tradicionalmente en afecciones catarrales, se informa sobre su cultivo y recolección, componentes químicos, usos populares y estudios preclínicos realizados. Los resultados obtenidos hasta el momentos permiten pronosticar una amplia utilización de la especie en el desarrollo de Medicamentos Herbarios indicados en afecciones catarrales y en epilepsia. Se consultaron las bases de datos MEDLINE (1966/1998). NAPRALERT (1995), International Pharmaceutical abstracts (1970/1993) y Chemical abstracts (1998).
