Calcium Oxalate Urolithiasis in the Rat: Is it a Model for Human Stone Disease? A Review of Recent Literature
Calcium oxalate stone disease is the most common human urinary stone disease in the Western Hemisphere. To understand different aspects of the disease, calcium oxalate urolithiasis in the rat is used as a model. Spontaneous calcium oxalate urolithiasis is very rare in rats. Thus the disease is experimentally induced and the rats are generally made hyperoxaluric either by administration of excess oxalate, exposure to the toxin ethylene glycol, or various nutritional manipulations. All the experimental models show renal injury associated with crystal deposition. Calcium oxalate crystals are in most cases intraluminal in renal tubules and often attached to the basal lamina of the denuded epithelium. Rat renal papillary tips and fornices appear to be the preferential sites for the deposition of large calcium oxalate calculi. Where urinary supersaturation of calcium oxalate has been studied the crystal forming rat urines are shown to have higher urinary supersaturation of calcium oxalate than their controls. Oxalate metabolism in the rat is nearly identical to that in humans. Thus, in a number of respects, experimental calcium oxalate urolithiasis in the rat is similar to calcium oxalate stone disease in man
Non-specific protein therapy
#1. Twenty cases of erysipelas have been treated
with milk injections, and a comparison made between
these and twenty similar cases treated by other
methods.
#2. Milk injections have their greatest value in
recurrent cases and in erysipelas 'migrans'.
#3. Twenty cases of asthma were treated by injections
of old tuberculin.
#4. This treatment is safe and successful in cases
of asthma which have failed to respond to other
methods of treatment.
#5. Twenty cases of rheumatoid arthritis were
treated by injections of typhoid -paratyphoid vaccine
#6. This treatment must be used with care and judg-
ment because it is apt to be followed by severe
reactions.
#7. Injection of vaccine should not be used as a
routine measure in rheumatoid arthritis, but may be
tried when other well -recognised forms of treatment
have failed.
#8. The treatment is most valuable in cases which
show synovial changes rather than in those which
showed marked bony change.
#9 . Twenty cases of general paralysis of the insane Acre
treated by malarial therapy.
#10. 45% of the cases were observed to have benefited
by this treatment for a period of at least
twelve months after injection.
#11. One case died as a direct result of malarial
treatment. Patients must be carefully selected for
this treatment.
#12. Improvement in the blood and cerebro- spinal
fluid is sometimes observed after treatment.
#13. Best results were obtained when anti - syphilitic
treatment was given before and after malaria
