The aim of this study was to determine the antibacterial activity of essential oil Minthostachys mollis “ruyaq muña”, against Helicobacter pylori, Shigella dysenteriae, Salmonella typhi and Pseudomonas aeruginosa. The leaves of M. mollis were collected in the district of Huamanguilla (3000-3200 m.s.n.m), Huanta province, Ayacucho region. The essential oil obtained by distillation with water vapor drag. The antibacterial activity was determined by plate cultive excavation method, resulting in order of sensitivity, for S. dysenteriae 21.41 mm; H. pylori 17,07 mm; S. typhi 14.25 mm and P. aeruginosa 11.45 mm. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for H. pylori were determined by the microplate dilution method, resulting in 2 μg/mL. For the other bacteria was determined by the dilution method, being for S. dysenteriae 4 μg/ml, S. typhi...

Heart rnitochondrion ATPase activity, ADP:O ratio (P:O) and Respiratory Control (RCR) are compared between guinea pigs from high altitude (Morococha, 4540 m) (HA) and those from sea level (SL). The study comprised 60 male guinea pigs, 30 from each altitude level, with mean weight 400-450 grams. Heart mitochondria were obtained by differential centrifugation at 4°C. P:O ratio and RCR were measured polarographically by Tyler method, and ATP hydrolysis was done by Holton et al. Method. Mean values obtained for heart mitochondria at SL and HA, expressed in mmoles oxygen uptake/mg protein/hour, were, with Glutamate + Malate as subtrates, respectiveIy: P:O 2.90, RCR 6.02 and P:O 2.93, RCR 6.0; and, with Pyruvate + Malate as subtrates, respectively P:O 2.60, RCR 5.0 and P:O 2.70, RCR 4.80. ATPase activity was at SL and HA, respectively: 57.50 and 64.50 mmoles P /mg protein/hour. The results su...
