 Peperomia {pep-er-o'-me-ah) \jTE-tpi, pepper]. Pepper 

 elder ; a genus of piperaceous plants, widely dis- 

 tributed in South America and the West Indies. Sev- 

 eral species have been used medicinally. P. rotun- 

 difolia is diaphoretic and antispasmodic. P. um- 

 bellata, a Brazilian species, is used as a diuretic. Unof.

 Pepsin ypep'-sin) [-iil>ig, 

 digestion]. The chief di- 

 gestive principle of the 

 gastric juice. It converts 

 albuminous substances in- 

 to peptones in the pres- 

 ence of an acid. It is 

 prepared by treating the 

 mucous lining of mamma- 

 lian stomachs with water 

 containing .2 to .3 per 

 cent, of hydrochloric acid. 

 P., Liq., contains saccha- 

 rated pepsin 40, hydro- 

 chloric acid 12, glycerin

 saccharatum, a mixture 

 of pepsin and sugar of 

 milk. Dosegr. v-jj. P., 

 Vinum. a solution of the 

 gastric ferments in sherry.

 Pepsinogen ( pep - sin'- o-

 yewav, to beget]. The 

 mother-substance, zymo- 

 1 gen or propepsin, existing 

 in the cells of the peptic 

 : glands of the stomach. 

 It is the antecedent of 

 pepsin, into which it is Peptic Gland from Stom-

 Pepsis (pep / -sis) [-eftc,

/eptic (pep* -fit) [-etiic, digestion]. Pertaining to 

 ; pepsin or to digestion. P. Glands, the fundus-glands 

 66 



of Heidenhain situated in the middle and cardiac 

 thirds of the stomach ; they secrete pepsin and hydro- 

 chloric acid. P. Ulcer, 

 the ordinary round ulcer 

 of the stomach, by some 

 ascribed to erosion of the 

 mucous membrane by the 

 gastric juice. 



Pepticity ( pep - tis ' -it- e) 

 [-i-reiv, to digest]. The 

 state of being peptic ; eu- 

 pepsia. 



Peptogaster {pep-to-gas' -

 yaorijp, belly]. The in- 

 testinal canal, or diges- 

 tive apparatus as a whole. 



Peptogastric { pep-to-gas' -

Peptogeny { pep-toj' -en-e) [Ve— reiv, to digest; yewav,

Peptoglutin Sublimate {pep-to-glu'-tin sub' -lim-dt). 

 Mercuric peptoglutin hydrochlorid. It contains 

 twenty-five per cent, of mercuric chlorid, in combina- 

 tion with a kind of semipeptonized gelatin. It is 

 used hypodermatically in syphilis. Dose gr. ^5, given 

 in a one per cent, solution, a Pravaz syringeful of 

 which is injected. 



Peptone {pep/ -ton) [-errreiv, to digest]. A proteid 

 body that is not precipitated by heat or by ammonium 

 sulphate, but which yields the biuret-reaction. This 

 is Kuhne 's peptone. Briicke's peptone is a proteid 

 which is not precipitated by potassium ferrocyanid. 

 but which yields the biuret-reaction. It is probably 

 a mixture of the peptone described by Kuhne and 

 an albumose. Peptones are produced by the action 

 of proteolytic ferments on albuminous substances, 

 e. g., in gastric and pancreatic digestion. They 

 are, unlike the proteids from which they are de- 

 rived, soluble, non-coagulable, and dialyzable. The 

 largest part of the albumins ingested in the food is 

 converted into peptones; these, however, are not 

 absorbed as such, but are reconverted into albumins 

 in the gastro-intestinal mucosa. Only a small quan- 

 tity of peptones passes into the blood. Globulin, acid- 

 albumin, para-peptone, propeptone, albumose, and 

 others are intermediate products formed during the 

 conversion of albumins into peptones. Peptone is 

 not present in the urine normally. P., Beef, a sub- 

 stance derived from beef by treating it with an extract 

 of the pancreas. Beef-peptone is extensively used in 

 bacteriologic laboratories in the preparation of media 

 made from meat-infusion. P., Pancreatic, a pep- 

 tone formed by the action of the pancreatic juice ; 

 unlike peptones resulting from digestion with gastric 

 juice, it is precipitated by acids and acid salts. 



Peptonemia {pep-to-ne' -me-ah ) [ttetttecv, to cook ; 

 a'tfia, blood]. The presence of peptone in the blood. 



Peptonization { ptp-to-niz-a' -shun) [irEirreiv, to digest]. 

 The process of converting proteids into peptones.
