[Clinical observation on multiple organ dysfunction syndrome due to fish gall bladder poisoning].
OBJECTIVE
To study the functional changes of liver, kidney, myocardium and gastro-intestine after fish gall bladder poisoning and the pathogenic mechanism of acute renal failure.


METHODS
The liver and kidney function, myocardial enzyme, urinary N-acetyl-beta-D-glucosaminidase (N-AG), 24 hrs intake and output volume of liquid and kidney B-ultrasonographic examination in 11 patients of severe acute fish gall bladder poisoning were observed. And kidney biopsy was carried out in one patient under B-ultrasonography for understanding the renal pathological changes.


RESULTS
All the 11 patients were cured with disappearance of clinical symptoms. After the poisoning the order of the severity of organ damage were kidney, liver, myocardium and gastro-intestine tract. The levels of blood creatinine, blood urea nitrogen, urinary N-AG, glutamic-pyruvic transaminase, total bilirubin were lowered significantly after treatment. Biopsy examination under light microscope showed toxic damage of renal tubules mainly in proximal tubules, and under electron microscope, the pathologic changes were mitochondrial vacuolar degeneration of tubular epithelial cells, swelling of epithelial cells, partial fusion of processes in glomeruli and narrowing of saccular cavity.


CONCLUSIONS
Fish gall bladder poisoning could cause acute multiple organ dysfunction syndrome (MODS), the affected organs in order of severity of damage were kidney, liver, myocardium and gastro-intestine tract. In kidney the damage was mainly at the proximal tubules. Urinary NAG is a sensitive criterion for determining the diagnosis and prognosis of renal tubular dysfunction.
