The whole body ether extracts of a marine prawn Nematopaleamon tenuipes and two gastropods viz. Euchelus asper and Hemifusus pugilinus, obtained by Soxhlet extraction and cold percolation were tested for their effects on phagocytosis by in vitro (slide method) and by in vivo (carbon clearance) methods. Extract of E. asper exhibits immunostimulatory activity in vitro and immunosuppressant activi...

this study assesses the effect of major trace metals levels in wastewater discharges and sedimentfrom twenty four permanent and five semi-permanent wastewater drain outlets into the kuwait coast. theeffect of trace metals levels released from untreated wastewater discharges to euchelus asper, gastropod was also determined. results showed high trace metal levels in e. asper tissues, followed by ...

The whole body ether extracts of a marine prawn Nematopaleamon tenuipes (PEP), two gastropods viz. Euchelus asper (EAE) and Hemifusus pugilinus (HPE), and acetone extract of a fish Rastrelliger kanagurta (MA), were tested for their effects on Delayed type Hypersensitivity (DTH) reaction and Plaque Forming Cell (PFC) assay. The Delayed type Hypersensitive reaction assay for HPE and PEP as well a...

Marine molluscs are widely distributed throughout the world and many bioactive compounds exhibiting antiviral, antitumor, antileukemic, and antibacterial activity have been reported worldwide. The present study was designed to investigate the beneficial effect of methanol extract of Euchelus asper (EAME) on estrogen deficiency induced osteoporosis in ovariectomised mice model. Forty-two female ...

We report the rediscovery of the exceedingly rarely collected and enigmatic fungus-farming ant species Mycetosoritis asper. Since the description of the type specimen in 1887, only four additional specimens are known to have been added to the world's insect collections. Its biology is entirely unknown and its phylogenetic position within the fungus-farming ants has remained puzzling due to its ...

Leaf extract of 12 medicinal plants were obtained by using 10mM sodium phosphate buffer and studied for their antibacterial activity against 6 cariogenic pathogens. Among them, the extract from Streblus asper showed the most intensive activity. Antibacterial activity of Streblus asper was investigated by the minimum inhibitory concentration (MIC) test and the viable cell count method. MIC of St...

The majority of snake bites in Central America are caused by Bothrops asper, whose venom induce complex local effects such as myonecrosis, edema and especially hemorrhage. These effects are only partially neutralized by the clinically used antivenom, even when administered rapidly after envenomation. Recently we screened 49 substances for antihemorrhagic activity and found that a mixture compos...
