Were studied the antioxidant effect and toxicity of the hot springs of San Antonio de Putina-Puno. Were used methods of lipid antiperoxidation, malondialdehyde (expressed as TBARS), in vivo oral acute toxicity at fixed dose according to 423 OECD and the physical chemistry composition by inductively coupled plasma source mass spectrometry (ICP-MS). The antioxidant effect presented significant difference between control group (0,0527 ŋm) and the study group (0,0390 ŋm) and malondialdehyde (p<0,05) and in vivo oral acute toxicity at fixed-dose treatment. Not evident signs of intoxication, moreover, in the composition of these hot springs were found: chloride 71,9%, sodium 80,3 % and sulphate 22,7% meq. Was concluded that the thermal mineral hot springs, are not toxic, have antioxidant effect and are chlorinated, sulphate and sodium type.

Se estudiaron el efecto antioxidante y la toxicidad de las aguas termales de San Antonio de Putina-Puno, por los métodos de antiperoxidación lipídica, malondialdehido (expresado como TBARS), la toxicidad aguda oral in vivo a dosis fijas según la OECD 423 y la composición fisicoquímica por espectrometría de pesos con fuente de plasma de acoplamiento inductivo (ICP-MS). El efecto antioxidante presentó diferencia significativa entre el grupo control (0,0527 ŋm) y el grupo estudio (0,0390 ŋm) malondialdehido (p<0,05) y en la toxicidad aguda oral in vivo a dosis fijas, después del tratamiento, no se evidenciaron signos de intoxicación, además en la composición de dichas aguas termales se encontraron cloruro 71,9%, sodio 80,3% y sulfato 22,7% meq. Se concluye que las aguas termales mineromedicinales, son atóxicas, tienen efecto antioxidante y son de tipo clorurada, sulfatada ...

In this study, was investigated the antistaphylococcal activity in vitro of ethanol and hydroalcoholic extracts of 3 peruvian medicinal plants: Juglans neotropica Diels (bark), Piper lineatum Ruiz & Pav. (leaves) and Terminalia catappa L. (leaves). The species were collected in the regions of Amazonas and Cajamarca, in Peru. Antistaphylococcal activity was assessed by microdilution method. The organisms used were bacteria Staphylococcus aureus ATCC 25923 and Staphylococcus epidermidis ATCC 12228. All extracts investigated showed significant activity against both bacteria with a minimum inhibitory concentration (MIC) of 125 to 500 μg/mL for Staphylococcus aureus, with increased activity of the ethanol extract of Juglans neotropica Diels, and of 250 to 500 μg/mL for Staphylococcus epidermidis, having greater activity the hydroalcoholic extract of Piper lineatum Ruiz & Pav.
