Results and discussion

Effect levels
Sex:
not specified
Dose descriptor:
other: lethal dose
Effect level:
10 other: g
Based on:
test mat.
Remarks on result:
other: Death occured thirty-six hours later
Mortality:
The animal lived for thirty-six hours (it is not clear if the dog was deliberately killed for further observations or if it naturally died)
Clinical signs:
no data
Body weight:
no data
Gross pathology:
Kidney
Same necrotic lesion of tubules but not so severe, a few hyaline casts in collecting tubules; no glomerular lesion. Fatty changes are most marked in the thick ascending limbs of the medullary loops, though occasionally also in convoluted tubules.

Liver
Some coarse fatty change and extensive fine vacuolization of liver cells.
Other findings:
Autopsy showed a marked edema of perirenal tissues.

Any other information on results incl. tables

The urine for the last twenty-four hours amounted to only a few cubic centimeters, and contained a small amount of albumin.

Observations in control animal

Urine: no albumin, usual picture of phlorhizin glucosuria

Kidney: some vacuolization of cells of loops of Henle. Cells of convoluted tubules are more granular than usual, but there is no

necrosis, no casts and no edema. The glomeruli are normal.

Liver: many cells show a fatty transformation with numerous fine fat droplets; other cells show no eosin-staining protoplasm, the nucleus persisting in a cell with fine colorless network. There are a few cells full of fat.

Pancreas: no changes.

Applicant's summary and conclusion

Conclusions:
10 g of D. Tartaric acid were given subcutaneously to a phlorhizinized dog which died thirty-six hours later the treatment.
Executive summary:

10 g of D. Tartaric acid were given subcutaneously to a phlorhizinized dog which died thirty-six hours later the treatment.
