The aim of the study was to explore the patterns of dental health services access in children under twelve years of age in Peru. Data from 25,285 children under 12 years who participated in the Demographic and Family Health Survey of 2014 were reviewed. An exploratory spatial analysis was performed to project the proportions of children with access to dental health services, according to national regions, type of health service and urban or rural place of residence. The results show that of the total sample, 26.7% had access to dental health services in the last six months, 39.6% belonged to the age group 0-4 years, 40.6% lived in the Andean region and 58.3% lived in urban areas. The regions of Huancavelica, Apurimac, Ayacucho, Lima and Pasco had the highest percentages of access nationwide. In conclusion, there is low access to dental health services in the population under 12 years of ...

The purpose of this study was to determine the carriage rate, susceptibility pattern, and serotype distribution of Streptococcus pneumoniae in the nasopharynx of children younger than 2 years old in Lima, Peru. A total of 666 children were evaluated during 3 periods, 1997, 2001, and 2003. The overall pneumococcal carrier rate was 41%. Reduced susceptibility to penicillin was found in 5% (4/75) of isolates in 1997, 20% (15/75) in 2001, and 37% (40/109) in 2003. Reduced susceptibility to ceftriaxone was found in 12% of isolates in 2003. Serogroups 6, 19, 23, 15, and 14 accounted for 68% of all the isolates and for 81% of the penicillin-nonsusceptible strains. Only 65% of the isolated strains had serogroups found in the 7-valent conjugate pneumococcal vaccine. This highlights the importance of regional surveillance studies for effective vaccine strategies and treatment protocols.

In order to know the effect of 60Co gamma irradiation, in the sunflower crop, were irradiated achenes in the Transelektro LGI-01 in the Instituto Nacional de Investigaciones Nucleares. The data was evaluated under a completely randomized design, where the treatments were 0, 100, 200, 300, 400, 500, 600, 700, 800 and 900 Gy and four repetitions (10x4) = 40 experimental units. The response variables were: plant height, root length and volume, dry biomass. The results indicated that germination and sprouting decreased as the radiation increased, adjusting these to a quadratic model. Plant height, length, root volume and dry biomass decreased at high doses. From this investigation it was concluded, that doses of 100 and 200 Gy, have a stimulating effect on plant height and root length, being an important agent, to induce genetic variability in sunflower.

Objectives: To determine the possible pharmacological interactions from the leaves of Maytenus macrocarpa with inhibitory and stimulating bowel motility drugs. Methods: We used 110 male albino mice with average weight of 25g, Arbos and others method was applied. Activated charcoal was administered at 5 % at dose of 0.1ml/10g, as an intestinal marker. The experimental groups included 0.1 ml/10 g of distilled water, leave extract of M. macrocarpa 1 (500mg/kg), leave extract of M. macrocarpa 2 (3000 mg/kg), 1,5mg/kg of atropine, 5mg/kg of loperamide, 0.4mg/kg of neostigmine, 10mg/kg of metoclopramide, leave extract of M. macrocarpa 1 with metoclopramide, leave extract of M. macrocarpa 1 with loperamide, leave extract of M. macrocarpa 2 with metoclopramide and leave extract of M. macrocarpa 2 with loperamide. The statistical validation was based on Wilconxon, ANOVA and Tukey test. Results: T...

OBJETIVO: Determinar las posibles interacciones farmacológicas de las hojas de Maytenus macrocarpa, con fármacos estimulantes e inhibitorios de la motilidad intestinal. MÉTODOS: Se utilizaron 110 ratones albinos machos, con pesos medios de 25 g, se empleó el método de Arbos y col, se administró carbón activado al 5 % vía oral, dosis de 0.1ml/10g, como marcador intestinal. Los grupos experimentales fueron: control (agua destilada 0,3ml), hojas de chuchuhuasi 1 (500mg/kg), hojas de chuchuhuasi 2 (3000mg/kg), atropina (1,5mg/kg), loperamida (5mg/kg), neostigmina (0,4mg/kg), metoclopramida (10mg/kg), hojas de chuchuhuasi 1 con metoclopramida, hojas de chuchuhuasi 1 con loperamida, hojas de chuchuhuasi 2 con metoclopramida y hojas de chuchuhuasi 2 con loperamida. Para la validación estadística se usó la prueba de Wilconxon, ANOVA y Tukey. RESULTADOS: El porcentaje de recorrido inte...
