toxocara canis (nematoda: ascaridae) is an intestinal nematode parasite of dogs, which can also cause disease in humans. transmission to humans usually occurs because of direct contact with t. canis eggs present in soil contaminated with the feces of infected dogs. this nematode has extraordinary abilities to survive for many years in different tissues of vertebrates, and develop to maturity in...

background thymus species are well known medicinal plants which the previous studies suggested the involvement of the opioid system in them. objectives this study aimed to investigate the effects of methanolic extract and essential oil of aerial parts of thymus daenensis (td), an endemic aromatic medicinal plant of iran, on morphine withdrawal syndrome in mice. materials and methods experiments...

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 confirmed by mass spectroscopy in Dracunculus medinensis and Ascaris suum. In addition, a morphine like substance has been isolated from Trichinella s...

The endogenous central nervous tissue substance called MLC (morphine-like compound) is shown to bind to the opiate receptors of the mouse neuroblastoma X glioma hybrid cell line NG108-15. The interaction of MLC with these opiate receptors is noncooperative, as is the interaction of morphine, naloxone, and Leu-enkephalin with these receptors. A specific antibody to morphine will bind MLC but wil...

A number of in-vitro model systems have been introduced for the study of the action of morphine-like drugs. Their usefulness depends on their relative simplicity, compared to the brain and central nervous system, and on the good correlation observed between potencies in the models and potencies in the whole animal. For example, the contractions of the isolated guinea\x=req-\ pig ileum and mouse...

Mice lacking the neurokinin-1 (NK1) receptor, the preferred receptor for the neuropeptide substance P (SP), do not show many of the behaviors associated with morphine reward. To identify the areas of the brain that might contribute to this effect, we assessed the behavioral effects of ablation of neurons expressing the NK1 receptor in specific regions of the mouse brain using the neurotoxin sub...

conclusions the results of the present study revealed that the aloe vera aqueous extract had various effects on morphine withdrawal syndrome in morphine-dependent female rats . results the results of the present study showed that agitation, disparity, and floppy eyelids in group e were significantly higher than those of others groups; however, these symptoms in group c were significantly lower ...
