A study of the microbiological assay of riboflavin
Autor: Olaf Bergeim, Ernst R. Kirch, Harold W. Woodson
Publikováno v: Journal of the American Pharmaceutical Association. American Pharmaceutical Association. 35
The values determined using a mixture of twenty amino acids compared favorably with those obtained using the customary media containing alkali‐treated peptone or casein hydrolyzate. For the riboflavin assay a new test organism, Lactobacillus delbru

Publikováno v: American journal of orthodontics. 33(2)
1. 1. Ammonia nitrogen developed in human saliva by natural processes has the ability to inhibit the growth of L. acidophilus. 2. 2. The inhibition of the lactobacilli is not due to the alkalinity which the ammonia might provide, for the same alkalin

Recent developments in the biologic production of ammonia and the use of ammonia and carbamide in caries prevention
Autor: J.F. O'Donnell, Ernst R. Kirch, Robert G. Kesel, Edward C. Wach
Publikováno v: Oral Surgery, Oral Medicine, Oral Pathology. 2:459-473
1. 1. More ammonia is formed in saliva than can be derived from the conversion of salivary urea. 2. 2. Amino acids are an important source of ammonia, and seventeen have been found to occur in saliva. 3. 3. Sugar in saliva has a depressing effect on

The amino acids and their deaminating systems present in human saliva
Autor: Ernst R. Kirch, Edward C. Wach, J.F. O'Donnell, Robert G. Kesel
Publikováno v: American Journal of Orthodontics and Oral Surgery. 33:B68-B79
1. 1. The free ammonia content of saliva from caries-free and caries-active individuals has not been proved to be significantly different. 2. 2. The source of ammonia nitrogen is not entirely urea; amino acids in saliva contribute to its formation. 3

Thiophosphoric Acid Derivatives of Ethylamine, DL-Methionine, and L-Proline Ethyl Esters I
Autor: Florence C. Klee, Ernst R. Kirch
Publikováno v: Journal of Pharmaceutical Sciences. 51:423-427
Thiophosphoric acid derivatives having structures similar to known anticholinesterases, were synthesized for the investigation of their possible enzyme inhibition in vivo. Based on theoretical considerations concerning structures of known chemotherap

Synthesis and Investigation of Certain Biological Activities of Some Thiophosphoric Acid Derivatives**Department of Chemistry, College of Pharmacy, University of Illinois, Chicago 12
Autor: Mitchell L. Borke, Ernst R. Kirch
Publikováno v: Journal of the American Pharmaceutical Association (Scientific ed.). 47:461-466
Two series of N-substituted phosphoroamidothioates and two phosphorochlorido-thioates were synthesized. Of these, eleven phosphoroamidothioates have not been prepared previously. The compounds were investigated for their activity in vitro toward Chol
