| Coffee contains caffein, a principle identical with theine and a modified form of tannin, though in less quantity than tea. |
|
| The mild stimulating property which cocoa possesses is due to the presence of the two substances, theobromine and caffein. |
|
| Diet was without any influence on the toxicity of the single dose of caffein. |
|
| This compound is water-soluble, but caffein can not be extracted from the crystals with anhydrous solvents. |
|
| For the headaches, phenacetin, alone or in combination with caffein and bromide of sodium, may be tried. |
|
| The presence of theobromine is peculiar to cocoa, but caffein is a stimulating principle which also occurs in tea and coffee. |
|
| The injurious action of caffein proceeds, according to Hoppe, from the spinal cord. |
|
| When cardiac muscle was poisoned with caffein, microscopical examination showed that the striations disappeared. |
|
| In both, the tonic with clonic convulsions were observed after a sufficient quantity of caffein was administered. |
|
| It is quite possible, therefore, that coccidiosis of the liver is an important factor in decreasing the resistance to caffein. |
|
| The beans are then steam distilled to remove the caffein, dried, and roasted. |
|
| When introduced by the intraperitoneal route, caffein is, on the contrary, distinctly less toxic. |
|
| The chief factors in coffee goodness are the caffein content and the caffeol. |
|
| This diet does not seem to be a factor, therefore, in the toxicity of caffein. |
|
| Weigh the residue as caffein and calculate on 7.5 grams of coffee. |
|
| In dog 28 the first dose of caffein 50 mg per kilo was toxic. |
|
| Aubert6 studied the toxicity of caffein in man and other animals. |
|
| The toxicity of caffein was studied in a large number of individuals. |
|
| Tannic acid, not as free acid, is combined with caffein as a tannate. |
|
| Salts of an unstable nature are formed with caffein by most acids. |
|
|
|
| This gives the total nitrogen due to both the proteids and the caffein. |
|
| The remainder of the caffein is probably eliminated as mono-methylpurins. |
|
| The rabbit aborted but recovered from the effects of caffein. |
|
| Observations with caffein were also made on the human subject. |
|
| These amounts of caffein proved fatal in all of the experiments on birds. |
|
| In this series the caffein was injected into the gluteal muscles. |
|
| Caffein aids the action of nitrates, acetanilid, ethyl alcohol and amyl alcohol, and increases the toxicity of barium chloride. |
|
| Caffein was therefore given by mouth and injected subcutaneously into the peritoneal cavity, into the muscles, and intravenously. |
