Administration / exposure

Route of administration:
other: intraperitoneal injection and subcutaneous injection
Vehicle:
not specified
Details on exposure:
It will be noticed that whereas in the second and third day animals the tartrate was administered subcutaneously, in the fifth day animals the dose was given intraperitoneally. This was because of the likelihood of necrosis and sloughing about the site of subcutaneous injections.
Analytical verification of doses or concentrations:
not specified
Duration of treatment / exposure:
5 days
Frequency of treatment:
no data
Doses / concentrations
Remarks:
Doses / Concentrations:
Tartrate nephritis was induced by subcutaneous/intraperitoneal injection of tartaric acid
The caffein in all cases was in the form of a 1% solution of the pure alkaloid, the strong saline was 5% NaCl solution, the adrenaline 1-1000 solution, the dog's urine filtered and undiluted. In every case the solutions were warmed and run into the femoral vein from a burette; the latter being washed out with 8 to 10 cc. 0.85 per cent salt solution. In the case of dogs A, C and 3, caffein solution was used in arbitrary doses of 2 cc., but in all other animals was given at the rate of 1 cc. per kilo. Strong saline was given at the rate of 5 cc. per kilo. Adrenalin was given in the arbitrary amount of 1 drop 1-1000 solution. Dog urine was given in arbitrary doses of 3 cc.
No. of animals per sex per dose:
In all, 32 dogs were used for this study including the normal controls.
The protocols of three normal controls follow. Three dogs were studied approximately twenty-four hours after poisoning, 3 dogs at forty-eight hours and 3 dogs after four days had elapsed. After each experiment thin blocks of kidney were fixed in Zenker's fluid, embedded in celloidin, cut and stained with hemalum and eosin.
Control animals:
yes, concurrent vehicle

Details on results:
Histological examination was made of the kidneys of 8 of the 9 animals reported above and varying degrees of degenerative and necrotic changes found in the tubular epithelium. The glomeruli were congested but no exudate was found in the subcapsular spaces. It would appear that the precipitate in the glomerular subcapsular space is not dependent upon the duration of the condition nor upon the mode of administration of the drug and that it is probably washed out in the course of active diuresis such as occurs in the physiological experiments.

Basis for effect level:
other: During the second and third days of tartrate nephritis in dogs the vascular reactions of the kidney are practically normal except that caffein does not produce a diuretic effect equal to that seen in normal dogs.

Any other information on results incl. tables

4 dogs died before there was opportunity to study the vascular reactions and all showed marked necrosis of the epithelium of the convoluted tubules. One of these animals survived only eight hours after the injection of tartrate (intraperitoneally) yet showed marked necrosis in addition to the glomerular condition, one other survived twenty-one hours (after subcutaneous injection) one survived twenty-four hours (intraperitoneal injection) and one survived forty-eight hours (subcutaneous ·injection).

Applicant's summary and conclusion

Conclusions:
Dogs with tartrate nephritis showed normal vascular reactions in the first 3 days whereas at 5th day the vascular reactions were somewhat more marked than normal and the diuretic effect of caffein was equal to that seen in normal animals.
Executive summary:

Dogs with tartrate nephritis showed normal vascular reactions in the first 3 days whereas at 5th day the vascular reactions were somewhat more marked than normal and the diuretic effect of caffein was equal to that seen in normal animals.
