Extract of sample "The drug PCP or called Phencyclidine"

Download file to see previous pages PCP operates as an NMDA receptor opponent that barricades the actions of the NMDA receptor plus, just as most antiglutamatergic hallucinogens, but is considerably more hazardous than other hallucinogens. Other NMDA receptor opponents include tiletamine, ketamine, nitrous oxide and dextromethorphan (Croft, 1998). Even though, the prime psychoactive consequences of PCP only take a few hours, its overall elimination rate from the body is up to nine days or longer. As a recreational treatment Phencyclidine may be smoked, ingested, or inhaled.
Phencyclidine is well recognized for its harmful effects on ionotropic glutamate receptors in rats’ brain homogenate as well as the NMDA receptor in rats. As such, Phencyclidine is an NMDA receptor opponent. NMDA receptors intercedes excitation. Studies, however, have proved that Phencyclidine produces extensive cortical activation in a human being as well as in rodents. Research also proves that Phencyclidine slows down nicotinic acetylcholine receptors. Analogues of Phencyclidine show unstable potency at nicotinic acetylcholine receptors as well as NMDA receptors. In several brain sections, these results are thought to operate synergistically by slowing down excitatory actions (Croft, 1998). Phencyclidine, like tiletamine, also acts as a D2 receptor limited agonist in the NMDA receptor of rats. This action is related to some of the psychotic aspects of Phencyclidine intoxication, which is verified by the use of D2 receptor antagonists for instance haloperidol in treating Phencyclidine psychosis. The relative resistance to pain is probably produced by the enkephalin system as well as indirect relations with the endogenous endorphin, as has been recommended by researches carried out to rats. Phencyclidine can also function as a dopamine reuptake inhibitor (Croft, 1998).

The Disease Called Polio

...are crippled for life and some of them die. But it is shown that a vast majority of people who are infected with the poliovirus do not even realize that they've been infected with polio. Researchers have found that the poliovirus attacks local lymphoid tissue, gets into the bloodstream, and later damage the cells of the central nervous system. The multiplication of poliovirus in motor neurons damages the cells particularly of the anterior horn and brain stem that results in appearances of poliomyelitis (Atkinson et al., 2009). Poliomyelitis is classified into two main types – the non-paralytic and the paralytic polio. Among some individuals the symptoms from the poliovirus doesn't lead to paralysis and these are called...

The Prison Called Marriage

...? Plot, setting, character, and theme: The prison called marriage in “The Story of an Hour” and “The Yellow Wallpaper” For women in the nineteenth century, marriage is a pair of handcuffs to their husbands, children, and houses. Kate Chopin’s (1894) “The Story of An Hour” (“ Hour”) and Charlotte Perkins Gilman’s (1899) “The Yellow Wallpaper” (“Yellow”) both support this disparaging conception of marriage. The nameless narrator of “Yellow” and Mrs. Mallard are both married women, who experience the struggles of being a wife. This essay compares these short stories using plot, setting, character, symbolism, and theme. These stories share the same plot that begins with marriage and ends with freedom.

A Man Called Horse

...Introduction The depiction of Native Americans from different sources has created specific impressions about the culture and what it means to belong to a marginalized group. The movies of the 1960s and past this time created a specific impression relating to what it meant to be a Native American and what it was to belong in the culture. The ideologies led to the audience believing that the Native American’s were foreigners in the country and had ways which did not relate to the other ways of living. In the movie, “A Man Called Horse,” produced in 1970, there is a direct correlation between living in the American lifestyle and living with the Native Americans.

Movie Called Side Effect

...her. Dr. Banks resorts to prescribing Emily Ablixa, a depression drug still undergoing trials. Although Emily complains to Banks about her sleepwalking and cooking, Banks dismisses it as a minor side effect (Brockway, 2013). Clearly, Banks dismissal was a wrong move considering it was a sign of Emily’s imminent psychotic break of murdering her husband. The projection method of psychoanalysis entails the consideration of a patient’s inner world and its projection onto the outer world (Lemma, 2003, p. 225). If Banks thoroughly employed this method, he possibly would have foreseen the horrible effects of Ablixa. Emily’s persuasion skills on Bank’s stance in court have a psychological basis (De Mesa, 2013). After Emily...
