Abstract

Background: Amaranthus spinosus and Andrographis paniculata are traditionally used as antimalarial herbs, but the combination of both has not yet been tested. The aim of this study was to determine the schizonticidal anti-malaria effect of a combination in Plasmodium berghei-infected mice.Methods: Male mice (Balb/c strain) weighing 28-30 g, 7-8 weeks old, were randomly devided into 5 groups of 4 animals each. Group A: controls (nil) and 4 treatment groups (B, C, D, and E). Group B: Amarathus 10 mg/kgBW, group C: Andrographis 2 mg/kgBW, group D: combination of Amaranthus + Andrographis 10 mg + 2 mg/kgBW. All treatment with plant extracts was administered orally, once per day for 7 days. Group E was given chloroquine 10 mg/kgBW, once a day orally, for 3 days.Results: The body weigh increased only in group D, hemoglobin concentration increased significantly vs controls (p < 0.05) in treatment groups C, D, and E, and blood schizonticidal activity was seen in all treatment groups, highest at almost 90% in groups D and E. Survival rate was 100% in all groups.Conclusion: The combination of Amaranthus and Andrographis (10 mg + 2 mg/kgBW) exerts the same blood schizonticidal activity as chloroquine 10 mg/kgBW.

Abstract

The study was conducted to determine the effect of land typology and lime on the population of indigenous nitrogen-fixing bacteria and soil pH, and to analyze the effect of soil typology interaction and lime on the population of indigenous nitrogen-fixing bacteria and soil pH. Sampling of soil in tidal land of Mulya Sari and Banyu Urip Village of Banyuasin Regency, South Sumatera. Then the sample was studied at the Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sriwijaya, Inderalaya. During January-May 2017. Based on the results of the study known the soil typology of the total population of nitrogen-fixing bacteria, the highest population of nitrogen inhibitor bacteria in the second week of soil typology D was 6.0x107 and the highest pH of 5.18 in typology B on week Third, the lime treatment that affected the population of indigenous nitrogen-fixing bacteria, obtained the population of bacteria as much as 9.3x105 in the second week and the highest soil pH 4.93 in the second week, while the results of the interaction between soil typology and lime treatment only affect the population of bacterial inhibitor Indigenous nitrogen, with bacterial population of 3.5x107 in soil typology D in the second week, but this interaction did not significantly affect soil pH, with the highest pH measurement of 5.33 on the soil typology D.Keywords: nitrogen-fixing bacteria, tidal land, lime treatment

Abstract

Background: Carbonic anhydrases (CAs) are metalloenzymes which catalyze the reversible hydration/dehydration reaction of CO2, in order to maintain the cell homeostasis. These enzymes are found in various tissues and involve in a number of different physiological processes, including ion transport, acid-base balance, bone formation, and gluconeogenesis. Objective: To examine the specific activity of CA and to observe the liver tissue respond to oxidative stress by measured the malondialdehyde (MDA) concentration, in rat liver tissue induced by chronic systemic hypoxia for 1, 3, 5, 7, and 14 days of hypoxia. Results: The study showed that the activity of CA induced by chronic systemic hypoxia significantly increasing at early exposure to the hypoxic condition, at day 1 and days 3 of hypoxia (0.281 and 0.262 nmol/mg protein/minute compared to control 0.155 nmol/mg protein/minute) (p<0.05). No statistical difference at treatments of hypoxia 5, 7, and 14 days. The concentration of MDA also increased significantly on day 3 of liver tissue hypoxia (0.013 nmol/mg compared to control 0.009 nmol/mg liver tissue) (p<0.05), and no statistical differences at day 1, 5, 7, and 14 days of hypoxia. Conclusion: There was damage of membrane cells affected by oxidative stress in the liver tissue of rats induced by chronic systemic hypoxia.
