The parasitic worm Ascaris suum contains the opiate alkaloids morphine and morphine-6-glucuronide as determined by HPLC coupled to electrochemical detection and by gas chromatography/mass spectrometry. The level of morphine in muscle tissue of female

The tissue distribution, course of secretion, and sex differences of morphine were delineated in Ascaris suum. Nitric oxide (NO) release in various tissues in response to morphine and its metabolite morphine-6-glucuronide (M6G) were also examined. As

Both morphine and anandamide significantly stimulated cultured endothelial intracellular calcium level increases in a concentration-dependent manner in cells pre-loaded with fura 2/AM. Morphine is more potent than anandamide (approximately 275 vs. 13

Opiates modulate nociception in vertebrates. This has also been demonstrated in a number of invertebrate models. Herein, the effect of the opiate morphine and opioid neuropeptides Endomorphin 1 and 2 on the thermal avoidance (Tav) behavior of Caenorh

The effects of the opiates morphine and morphine-6-glucuronide (M6G), the μ opioid receptor specific antagonist D-Phe-Cys-Tyr-D-Trp-Om-Thr-Pen-Thr-NH2 (CTOP), and the general opiate antagonist naloxone on the latency of response to thermal stimulati

Bifenthrin is a synthetic pyrethroid insecticide derivative of naturally occurring pyrethrins from chrysanthemum flowers. Bifenthrin is considered relatively safe and therefore incorporated as the active ingredient in preparations sold over the count

Here, we addressed the concern that, despite the lack of overt toxicity, exposure to low levels of the common household pyrethroid pesticide, bifenthrin, could cause harm to the immune system. To do this, we measure the effect of bifenthrin on phytoh

R ECENT studies have used the blue mussel, Mytilus edulis, as a sentinel organism for pollution (Greig & Sennefelder 1985; Micallef & Tyler 1989). The mussel and other marine mollusks, such as oysters and clams, have long been known to concentrate to

Bifenthrin is a third generation member of the synthetic pyrethroid family of insecticides. As a new pesticide within a relatively new class of pesticides, bifenthrin is considered relatively safe. Here, we used the PC12 neuronal cell line to examine

The current paper summarizes the findings on endogenous morphine isolated by HPLC and characterized by mass spectroscopy in Schistosoma mansoni, Dracunculus medinensis and Ascaris suum. Morphine-6-glucuronide (M6G) has also been found by HPLC and con
