On Ox Gall

Comparison of Loeffler's Coagulated Blood Serum and Blood Serum with the Addition of Sterile Ox Gall.

In 1913 Von Drigalski and Bierast reported on the results obtained by the comparative use of Loeffler's original coagulated blood serum plate medium and blood serum medium with the addition of sterile ox gall, in the isolation of the diphtheria bacilli. Drigalski's medium was prepared according to the original formula with the addition of 0.13 parts ox gall. They concluded from their work that ...

Studies on Gall Bladder Function

The data obtained from the experiments on dogs reported in this paper lead us to conclude that bile pigment is not absorbed from the gall bladder bile. The mean loss of pigment is so small when compared with the amount of water lost that it is negligible. Our cholesterol data do not support the concept that this substance is secreted into the gall bladder bile of the dog under normal conditions...

Studies on nitrogen pool of animal tissues. I. Ox ocular tissues. II. Ox nervous tissues.

Concentrations of ampholytes in the nitrogen pool of ox ocular tissues and nervous tissues were analyzed systematically by an automatic amino acid analyzer with a special reference to their minor components. DCEC was found in lens and also in nervous tissues. Ophthalmic acid was found in lens (highest), in retina (moderate), and in vitreous humor and spinal cord (trace). Glutathione content was...

Ox liver glutamate dehydrogenase

1. The effect of pyridoxal 5'-phosphate on the activity of ox liver glutamate dehydrogenase towards different amino acid substrates was investigated. 2. Both alanine and glutamate activities decreased steadily in the presence of pyridoxal 5'phosphate. 3. The alanine/glutamate activity ratio increased as a function of inactivation by pyridoxal 5'-phosphate, indicating that glutamate activity is ...
