The aim of this research was to investigate antidiabetic activity of Costus igneus (also known as insulin plant) leaves extracts in streptozotocin induced diabetic albino rats. A comparison was made between the action of Costus igneus extract and a known antidiabetic drug glibenclamide (5mg/kg body wt.). An oral glucose tolerance test (OGTT) was also performed in experimental diabetic rats. Eth...

The distributions of American cicada killers (Sphecius) were examined via solicited and museum specimens. S. hogardii occurs in southern Florida and several Caribbean islands. S. speciosus occurs throughout the east coast, southeast, and Midwestern states at high densities, and its range extends much farther west than expected, but not west of the continental divide. S. speciosus appears to be ...

INTRODUCTION The nephroprotective effect of the aqueous extract of Costus afer leaves was evaluated in male albino Wistar rats with gentamicin-induced kidney injury. MATERIALS AND METHODS In a 2-phase study, 30 weight-matched male Albino Wistar rats were divided into 6 groups of 5 animals to receive gentamicin, 90 mg/kg/d (except for the control group) for 7 days in the first phase to induce ...


 Purpose: To Investigate the antiproliferative effect of n-hexane-diethyl ether fraction Costus speciosus (NP) on triple negative breast cancer (MDA-MB-231) cells, and mechanism involved.
 Methods: Maceration with methanol (CH3OH) was used for extraction rhizomes. Chromatographic separation to obtain non-polar via elution n-hexane:(C2H5)2O at a volume ratio 9:1. The cytotoxic NP eval...

Species can arise via the divisive effects of allopatry as well as due to ecological and/or reproductive character displacement within sympatric populations. Two separate lineages of Costaceae are native to the Neotropics; an early-diverging clade endemic to South America (consisting of ca. 16 species in the genera Monocostus, Dimerocostus and Chamaecostus); and the Neotropical Costus clade (ca...
