99mTc-DTPA Galactosyl Human Serum Albumin Scintigraphy in Mushiroom Poisoning Patient: Comparison with Liver Ultrasonography / 대한핵의학회잡지

99mTc-galactosyl human serum albumin (Tc-GSA) is a radiopharmaceutical that binds to asialoglycoprotein receptors, which are specifically present in the hepatocyte membrane. Because these receptors are decreased in hepatic parenchymal damage, the degree of Tc-GSA accumulation in the liver correlates with findings of liver function test. Hepatic images were performed with Tc-GSA in patients with acute hepatic dysfunction by Amantia Subjunquillea poisoning, and compared with these of liver ultrasonography (USG). Tc-GSA (185 MBq, 3 mg of GSA) was injected intravenously, and dynamic images were recorded for 30 minutes. Time-activity curves for the heart and liver were generated from regions of interest for the whole liver and precordium. Degree of hepatic uptake and clearance rate of Tc-GSA were generated by visual interpretation and semiquantitative analysis parameters (receptor index: LHL15 and index of blood clearance: HH15). Visual assessment of GSA scintigraphy revealed mildly decreased liver uptake in all of subjects. The mean LHL15 and HH15 were 0.886 and 0.621, graded as mild dysfunction in 2, and mild to moderate dysfunction in 1 subject. In contrast, liver USG showed no remarkable changes of hepatic parenchyme. Tc-GSA scintigraphy was considered as a useful imaging modality in the assessment of the hepatic dysfunction.

Clinical manifestations of amanita subjunquillea poisoning / 대한내과학회지

BACKGROUND: To the best of our knowledge, the report on Amanita subjunquillea poisoning has not been found in the medical literature. We investigated the clinical aspects of Amanita subjunquillea poisoning. METHODS: Sixteen subjects who had ingested the mushroom (A. subjunquillea) were examined for clinical features, laboratory and radiologic findings prospectively. RESULTS: The mean incubation period was 11.5 hours(range: 3 to 17 hours). The initial presentations were gastrointestinal symptoms which persisted for 2 to 4 days. The transaminase levels were elevated in all subjects and peaked on day 3 after ingestion of the mushrooms (mean AST/ALT levels : 3241 IU/L and 3741 IU/L, respectively). Biochemical evidence of pancreatitis and disseminated intravascular coagulation were frequent (83.3% and 62.5%, respectively). Liver ultrasonography and scintigraphy revealed abnormalities in most cases. Massive hepatic necrosis was confirmed by liver biopsy in one subject. The overall mortality was 12.5%. CONCLUSION: Clinical manifestations of A. subjunquillea poisoning were similar to those of other poisonous Amanitaceae intoxication. However, the mortality rate was lower in A. subjunquillea poisoning. Our data showed strong evidence that A. subjunquillea should be classified in the group of poisonous mushrooms.
