ptomato-, ptomat-, pto-, -ptosia, -ptosis, -ptoma, -ptot- +

Ptosis (drooping), or prolapse (falling down or sinking) of the male gonads.

Pendulosity (loosely drooping or hanging down) of the scrotum.

A generalized descent, prolapse, or droop of the abdominal viscera.

Downward displacement of the diaphragm.

The forward displacement of an organ, especially an eyeball.

1. Any of a class of foul-smelling nitrogenous substances produced by bacteria during putrefaction of animal or plant protein; formerly thought to be toxic.
2. A basic nitrogenous organic compound produced by bacterial putrefaction of protein.
3. A term for food poisoning that is no longer in scientific use; food poisoning was once thought to be caused by ingesting ptomaines.
4. The generic name of certain alkaloid bodies found in putrefying animal and vegetable matter, some of which are very poisonous.
5. Etymology: from Greek ptoma, "corpse"; literally, "a falling, a fallen thing"; from piptein, "to fall".

The conception is of poison produced in decaying matter. Incorrectly formed; the proper Greek would be ptomatine.

The presence of one or more ptomaines in the blood.

1. Food poisoning, erroneously believed to be the result of ptomaine ingestion. It is no longer in scientific use.
2. Etymology: Via French from Italian ptomaina; from Greek ptōma, "fallen body, corpse" and Greek piptein, "to fall".

It was once thought that food poisoning was a result of bacterial toxins, but this has been rejected by scientists.

The identification of certain alkaloidal substances, or ptomaines, is of great interest to toxicologists. In 1881, the discovery of Professor Selmi as to the formation of poisonous alkaloids, which he calls ptomaïnes, in the human body after death. In 1884, these "cadaveric" alkaloids, or "ptomaines" as they have also been called. In 1891, the chemical ferments produced in the system, the albumoses or ptomaines which may exercise so disastrous an influence.

Italian ptomaina, erroneously formed by Professor Selmi of Bologna, from Greek fallen, "body, corpse". Professor Selmi's first paper in Annali di Chimica (1876), announced the body as "la potomaina o prima alcaloide dei cadaveri"; but this was partly corrected in his work of 1878 to ptomaina. It is to be regretted that the full correction to ptomatine was not made at its reception into English.

Poisoning by a ptomaine.

The presence of ptomaines in the urine.

A previous term for autopsy.

A former term for autopsy.

A ptomaine characterized by poisonous properties similar to those of atropine (toxic alkaloid); formed by the action of bacteria in the decarboxylation (removal of the carboxyl group) of amino acids.

1. An abnormal lowering or drooping of an organ or a part; especially, a drooping of the upper eyelid caused by muscle weakness or paralysis.
2. An abnormal downward displacement of the upper lid, as may result from paralysis of the third cranial nerve, sympathetic denervation, or injury; also called, lid drop.

1. A reference to ptosis (abnormal lowering or drooping of an organ or a part).
2. Affected by or pertaining to ptosis.
