In Lima during the summer months, ambulatory sales do not meet quality standards for the sale of bottled water. A recent study by Shotyk et al, reported elevated levels of antimony in potable water stored in polyethylene terephthalate (PET) containers1 For this reason, the concentration of antimony in bottled water was studied in three samples during the months of February and March of 2013 of ambulatory sale on Alfonso Ugarte and Nicolás de Piérola avenues of metropolitan Lima in relation to the environmental temperature of sampling and the time of packaging. It was found that the average concentration of antimony on Alfonso Ugarte avenue was 1610 ng/L, The average concentration of antimony on Nicolás de Piérola avenue was 1600 ng/L. The antimony concentration of the samples of bottled water of ambulatory sale on Alfonso Ugarte and Nicolás de Piérola avenues was less than the máx...

En Lima durante los meses de verano, la venta ambulatoria no reúne los estándares de calidad para la venta de agua embotellada. Un estudio reciente de Shotyk y colaboradores, reportó niveles de antimonio elevados en el agua potable almacenada en envases de tereftalato de polietileno (PET). Por eso, se estudió la concentración de antimonio en agua embotellada de venta ambulatoria, en tres muestreos durante los meses de febrero y marzo del 2013 en las avenidas Alfonso Ugarte y Nicolás de Piérola de lima metropolitana en relación a la temperatura ambiental de muestreo y al tiempo de envasado. Se encontró que la media de concentración de antimonio en la avenida Alfonso Ugarte fue de 1610 ng/L, la media de concentración de antimonio en la avenida Nicolás de Piérola fue 1600 ng/L. La concentración de antimonio de las muestras de agua embotellada de venta ambulatoria en las avenid...

The present investigation was carried out with the objective of knowing if the traffic policemen of the city of Huancayo in 2019 exceeded the normal values of carboxyhemoglobin in blood, for which the carboxyhemoglobin COHb) was quantified in the blood of 64 traffic policemen. The study was carried out based on the scientific research method, a type of applied research and a non-experimental-descriptive and cross-sectional research design. The parametric statistical method was also used. The results showed that 40 (62.5%) gave lower than normal COHb values and 24 (37.5%) gave higher than normal COHb values, being that the normal value of carboxyhemoglobin in blood is from 1 to 2 %. The values according to gender were obtained 28.1% in women and 9.4% in men with higher than normal COHb values. Regarding age, it was divided into four groups, finding levels higher than the normal COHb value...

The purpose of this study was to assess whether the loss of fur and changes in liver enzymes, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), produced in albino mice by oral administration of carbon tetrachloride and dimethyl sulfoxide (DMSO) (1:1), 2 mL/kg dose, are reversible processes when administered modified aloe gel (GSM) orally daily dose of 8 mL/kg of weight. Tests carried out at 13, 18 and 33 days from starting treatment with GSM, was evidenced significant and progressive decrease in AST and ALT without significant variations in proteins and phosphatases; whereas triglyceride level by the effect of GSM (group B), experienced significant decrease during the first week compared to mice given CCl4+DMSO mixture (group A), specimens that also recovered the fur on its chest and muzzle at 33 days of starting the experiment. The mice in the groups: control, GSM, DM...

The aim of this study was to evaluate the hepatoprotective effect of Aloe vera modified gel (MAVG) against the injury induced in albino mice by the oral administration of mixed overheated cooking oil (OCO) with dimethyl sulfoxide (DMSO) (1:1). OCO doses used were 2,3 and 3,1 mL/kg administered for 14 days, which produced increases of transaminases ALT, AST and triglycerides. For the specimens that received the lowest dose of OCO (2,3 mL/kg body weight), since day 14 and continuing for 18 days, were administered additionally four drops daily of MAVG equivalent to 6,1 ml/kg. When analyzing the results obtained at 14, 19, 28 and 33 days of starting treatment were observed significant progressive decrease in ALT, AST and triglycerides. However, the specimens that received the highest dose of OCO (3,1 ml/kg) plus MAVG, showed increase in the levels of ALT, AST and triglycerides over time, sug...

El objetivo del presente estudio fue evaluar el efecto hepatoprotector del gel de Aloe vera modificado (GAVM) frente a la injuria inducida en ratones albinos por la administración, vía oral, de aceite comestible recalentado (ACR) mezclado con dimetilsulfóxido (DMSO) (1:1). Las dosis de ACR usadas fueron 2,3 y 3,1 mL/kg, administradas por 14 días, lo cual produjo incremento de las transaminasas (ALT, AST) y triglicéridos. A los ejemplares que recibieron la menor dosis de ACR (2,3 mL/kg de peso), a partir del día 14 y por 18 días, se les suministró, adicionalmente, cuatro gotas diarias de GAVM equivalente a 6,1 mL/kg de peso. Al analizar los resultados obtenidos a los 14, 19, 28 y 33 días de iniciado el tratamiento, se observó disminución progresiva significativa de ALT, AST y triglicéridos. Sin embargo, los ejemplares que recibieron mayor dosis de ACR (3,1 mL/kg de peso) más ...
