Kashiwado 1 has suggested the use of stained cell nuclei in this test. 

 A preparation put out under the name " Gefarbte gewebskerne zur 

 Pankreasfuntionspriifung nach Prof. Dr. Schmidt und Dr. Kashiwado" 

 consists of a mixed preparation of thymus cells, the nuclei of which 

 are stained by iron hematoxylin, and lycopodium powder. After 

 administration, the lycopodium, which is readily recognized, is sought 

 for in the stool and when found that portion is examined for the stained 

 thymus cells. Their statement is as follows: If stained nuclei are 

 not found in the feces after an intestinal transit of sufficient duration 

 (at least six hours) normal pancreatic function (external) is indicated. 

 If, however, all or part of the cells are found, a definite disturbance in 

 pancreatic function is present.

 mixed diet, take the indicated dose of one of the following drugs, "separate"

 stools evacuated : 



18. Einhorn's Bead Test. 2 This is a method for testing the digestive func- 

 tion. In some respects it is similar to Sahli's desmoid reaction (see Gastric 

 Analysis). The procedure consists in wrapping the material under examination 

 (catgut, fish-bone, raw beef, cooked potatoes, thymus gland or mutton fat, etc.) 

 in gauze to which glass beads of various colors are attached and enclosing gauze
