PATHOLOGICAL CURVES 



Pathologically any variation may occur, each variation 

 type typical of its stomach disorder. But a consideration 

 of their interpretation is outside the purpose of the present 

 paper. 



Charts of (1) Gastric ulcer, and (2) Carcinoma have 

 been prepared v^^ith slight analysis showing as far as pos- 

 sible how the laboratory examination goes. 



1. Case of Gastric Ulcer: Tender point, persistent oc- 

 cult blood. There is an excess of hydrochloric acid in about 

 one-half the cases. In the other cases the acid is normal 

 or diminished. The findings are: (1) a rapid rise in half 

 an hour, (2) distinct, rather abrupt hyperacidity, (3) 

 rapid decline, (4) usually occult blood. The diagnosis must 

 be based largely upon clinical evidence. Chart No. 4

2. Case of Carcinoma: As far as the laboratory find- 

 ings go the cardinal signs are absence of free acid, blood in 

 all specimens, and Oppler-Boas bacilli in large numbers. It 

 is probable that some substance is produced by the cancer
