Evaluation of the efficacy and toxicity of oral and topical pumpkin oil on the hair growth of mice.

This study aimed to evaluate the efficacy and safety of a topical and oral administration of pumpkin seed oil (PSO) on the hair growth of BALB/c male mice. The animals had their dorsal area shaved (2 ×2 cm) and they were divided into 6 experimental groups. They received orally saline (OS), finasteride (F), or PSO (OP) for 14 days; or topically saline (TS), minoxidil (M), or PSO (TP) for 7 days. The euthanasia of all of the mice occurred on the 22nd day, and the histological slides from the skin area were analyzed. Lipoperoxidation in the liver was assessed through the TBARS method and was also evaluated by the antioxidant enzymes (SOD and CAT). The comet assay and the micronucleus tests were performed for genotoxic/mutagenic safety analyses. A significant increase in the number of hair follicles in the TP group was seen (8.8 ± 0.8) but it was disorganized, with loose dermal collagen. Finasteride presented a significant increase in the levels of the TBARS, SOD, and CAT in the liver, and M increased the DNA damage in the blood and the liver tissues. PSO did not induce any significant changes. In addition, PSO did not induce genotoxic or mutagenic effects. In conclusion, the oral PSO for 14 days acted in the proliferation of the hair follicles, without toxicity signals in the liver.

[Prescribed and unprescribed drug use among pregnant patients attended by the Unified Health System in Santa Rosa (State of Rio Grande do Sul, Brazil)]. / Utilização de medicamentos por gestantes usuárias do Sistema Único de Saúde no município de Santa Rosa (RS, Brasil).

In order to ascertain the use of prescribed and unprescribed drugs among pregnant patients of the Unified Health System (SUS), a descriptive study comprised of a sample of pregnant women was carried out in the city of Santa Rosa, State of Rio Grande do Sul, Brazil. Data were collected by means of structured interviews and consultation of patient records of pregnant women in the prenatal period. The prevalence of drug use was 90%, corresponding to an average of 4.1 drugs per pregnant woman, of which 83.6% were prescribed and 16.4% were self-medicated. Of this total, 17.5% of the drugs were included in fetal risk category C. The use of drugs during pregnancy is frequent and the majority of the pregnant women used one or more prescribed and unprescribed drugs during pregnancy. These data suggest the need for preventive measures to promote rational drug use during pregnancy.

Com o objetivo de descrever o uso de medicamentos prescritos e não prescritos, realizou-se um estudo descritivo em gestantes em pré-natal no Sistema Único de Saúde (SUS) no município de Santa Rosa, Estado do Rio Grande do Sul. Os dados sobre o uso de medicamentos foram coletados através de entrevista estruturada e consulta aos prontuários das gestantes. A prevalência do uso de medicamentos foi de 90 por cento, correspondendo a uma média de uso de 4,1 medicamentos por gestante, dos quais 83,6 por cento foram prescritos e 16,4 por cento foram utilizados por automedicação. Do total de medicamentos, 17,5 por cento estão incluídos na categoria C de risco ao feto. O uso de medicamentos é frequente, e a maioria das gestantes utilizou um ou mais fármacos prescritos ou não prescritos. Esses dados sugerem a necessidade de medidas de intervenção para promover o uso racional de medicamentos durante a gestação.
