Polidocanol
|
D000077423 |
[An alkyl polyglycol ether of LAURYL ALCOHOL, chemically defined as an alcohol ethoxylate having an average alkyl chain of 12–14 carbon atoms, and an ethylene oxide chain of 9 ethylene oxide units. It is used as a detergent, and medically as a local anesthetic, and as a sclerosing agent for the treatment of ESOPHAGEAL AND GASTRIC VARICES and VARICOSE VEINS.

|
Poliomyelitis
|
D011051 |
[An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (From Adams et al., Principles of Neurology, 6th ed, pp764-5)

Poliomyelitis, Bulbar
|
D011052 |
[A form of paralytic poliomyelitis affecting neurons of the MEDULLA OBLONGATA of the brain stem. Clinical features include impaired respiration, HYPERTENSION, alterations of vasomotor control, and dysphagia. Weakness and atrophy of the limbs and trunk due to spinal cord involvement is usually associated. (From Adams et al., Principles of Neurology, 6th ed, p765)

Poliovirus
|
D017955 |
[A species of ENTEROVIRUS which is the causal agent of POLIOMYELITIS in humans. Three serotypes (strains) exist. Transmission is by the fecal-oral route, pharyngeal secretions, or mechanical vector (flies). Vaccines with both inactivated and live attenuated virus have proven effective in immunizing against the infection.

|
Poliovirus Vaccine, Inactivated
|
D011054 |
[A suspension of formalin-inactivated poliovirus grown in monkey kidney cell tissue culture and used to prevent POLIOMYELITIS.
] |
|
Poliovirus Vaccine, Oral
|
D011055 |
[A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)

Poliovirus Vaccines
|
D023321 |
[Vaccines used to prevent POLIOMYELITIS. They include inactivated (POLIOVIRUS VACCINE, INACTIVATED) and oral vaccines (POLIOVIRUS VACCINE, ORAL).

Pollen Tube
|
D053205 |

] |
|
Pollination
|
D054817 |
[The transfer of POLLEN grains (male gametes) to the plant ovule (female gamete).

Polonium
|
D011059 |
[A radioactive element that is a member of the chalcogen family. It has the atomic symbol Po, atomic number 84, and the atomic weight of the isotope with the longest half-life (209Po) is 208.98. It decays by alpha-emission.

Poloxamer
|
D020442 |
[A nonionic polyoxyethylene-polyoxypropylene block co-polymer with the general formula HO(C2H4O)a(-C3H6O)b(C2H4O)aH. It is available in different grades which vary from liquids to solids. It is used as an emulsifying agent, solubilizing agent, surfactant, and wetting agent for antibiotics. Poloxamer is also used in ointment and suppository bases and as a tablet binder or coater.
