The aim of the present work was to examine the immunopharmacological (anti-microbial and anti-inflammatory) effect of saponin on human peripheral blood mononuclear cells (PBMC) that are isolated as well as purified from infected (virally) and non-infected (normal) human whole blood samples. However, there is little information available concerning the effect of crude saponin on human PBMC in ca...

A number of different markers (proteins, isoenzymes and RAPDs) have been used to settle taxonomic disputes and to assess genotype variability in populations of the genus Prosopis, in order to select highly productive phenotypes. In this study the genetic variability of two wild populations of Prosopis laevigata located in the Mexican states of Guanajuato (population 1) and Hidalgo (population 2...

Prosopis alba seedlings, that grew at the 45 dS m salinity level in a previous study of growth and survival of Argentine and Peruvian Prosopis, were propagated by rooting cuttings and established in a seed orchard/long term evaluation trial on soils with low salinity (EC 5.1–7.5 dS m) but high pH (8.9 to 10.2). A pH gradient occurred in the field with values ranging from pH 9.4 in block 1 to pH...

Ecophysiological traits of Prosopis juliflora (Sw.) DC. and a phylogenetically and ecologically similar native species, Anadenanthera colubrina (Vell.) Brenan, were studied to understand the invasive species' success in caatinga, a seasonally dry tropical forest ecosystem of the Brazilian Northeast. To determine if the invader exhibited a superior resource-capture or a resource-conservative str...

Objective: In 2007 the Rajasthan state of India reported 55,000 malaria cases and 46 deaths caused by malaria. District Jodhpur is the gateway to the Thar Desert in Western Rajasthan. Here malaria is endemic. Between 2002 and 2006 the slide positivity rate ranged between 0.56% and 2.29 % in Jodhpur. The present study aimed to identify factors associated with malaria in Jodhpur. Methods: An age ...

The Afrotropic subgenus Deranchylaeus; of the colletid bee genus Hylaeus is revised for the first time on the basis of all the available type material. Here, 28 new synonymies were detected: Prosopis flaviscutum Alfken and Hylaeus graaffi Cockerell = H. curvicarinatus (Cameron); H. microstictus Cockerell = dregei (Strand); H. bequaertianus Bridwell and H. ogilviei Cockerell = H. gabonicus (Vach...

The air dried leaves of Prosopis juliflora Swartz DC., commonly known as Vilayati Kikar was analyzed for chemical composition. The results revealed the quantitative analysis of following classes of natural constituents: flavonoids, alkaloids, saponins, phenols and tannins in the range of (16 ± 0.39), (3.6 ± 0.06), (2.2 ± 0.23), (0.66 ± 0.11) and (0.33 ± 0.07) % respectively. The crude fiber and...
