OBJECTIVETo investigate changes in renal function, urine N-acetyl-beta-D-glucosaminidase enzyme (N-AG),liver function, myocardial enzymes, the pathology of renal damage and the mechanism of acute renal failure (ARF) associated with fish gall bladder poisoning.
METHODSEleven patients with acute fish gall bladder poisoning were consecutively admitted to our hospital from September 1997 to October 1999. Renal function, urine N-AG enzyme, liver function, and myocardial enzymes were assayed before and after treatment. One patient consented to a kidney biopsy and the pathology of renal damage was observed under light and electron microscopes.
RESULTSAll patients had multiple organ dysfunction syndrome (MODS) and 11 patients suffered from ARF. Ten patients had liver dysfunction, ten patients had poisonous myocarditis, and 8 patients had gastrointestinal dysfunction. Renal function, urine N-AG enzyme, liver function, and myocardial enzymes were significantly improved after treatment compared with those of before treatment (P < 0.05). Kidney biopsy showed that the main damage site was the proximal renal tubule. All eleven patients recovered and were discharged from the hospital.
CONCLUSIONSIngestion of fish gall bladder leads to kidney damage, as well as liver, heart and gastrointestinal tract injury. The mechanism of acute renal function failure is the serious tubular damage, confirming the location of kidney damage. Necrosis of the proximal tubules plays an important role in the development of ARF. Immediate hemodialysis is the most effective treatment.

OBJECTIVE:
To separate and determine scopolamine from the food in a poisoning case by GC/MS.
METHODS:
The scopolamine was determined by GC/MS/El used CP5860(CP-sil8CB) column (30 mx 0.25 mmx 0.33 microm) with liquid- liquid extraction.
RESULTS:
The deny scopolamine was found in the case sample, and the chromatographic separation of the peaks is fine.
CONCLUSION
The method is accurate and reliable.

OBJECTIVES: In July 2 2010, a diarrhea outbreak occurred among the workers in a company in Gyeungju city, Korea. An epidemiological investigation was performed to clarify the cause and transmission route of the outbreak. METHODS: We conducted a questionnaire survey among 193 persons, and we examined 21 rectal swabs and 6 environmental specimens. We also delegated the Daegu Bukgu public health center to examine 3 food service employees and 5 environmental specimens from the P buffet which served a buffet on June 30. The patient case was defined as a worker of L Corporation and who participated in the company meal service and who had diarrhea more than one time. We also collected the underground water filter of the company on July 23. RESULTS: The attack rate of diarrhea among the employees was 20.3%. The epidemic curve showed that a single exposure peaked on July 1. The relative risk of attendance and non-attendance by date was highest for the lunch of June 30 (35.62; 95% CI, 2.25 to 574.79). There was no specific food that was statistically regarded as the source of the outbreak. Bacillus cereus was cultured from two of the rectal swabs, two of the preserved foods and the underground water filter. We thought the exposure date was lunch of June 30 according the latency period of B. cereus. CONCLUSIONS: We concluded the route of transmission was infection of dishes, spoons and chopsticks in the lunch buffet of June 30 by the underground water. At the lunch buffet, 50 dishes, 40 spoons, and chopsticks were served as cleaned and wiped with a dishcloth. We thought the underground water contaminated the dishes, spoons, chopsticks and the dishcloth. Those contaminated materials became the cause of this outbreak.

6.Environmental and health effects associated with Harmful Algal Bloom and marine algal toxins in China.
Biomedical and Environmental Sciences 2004;17(2):165-176
The frequency and scale of Harmful Algal Bloom (HAB) and marine algal toxin incidents have been increasing and spreading in the past two decades, causing damages to the marine environment and threatening human life through contaminated seafood. To better understand the effect of HAB and marine algal toxins on marine environment and human health in China, this paper overviews HAB occurrence and marine algal toxin incidents, as well as their environmental and health effects in this country. HAB has been increasing rapidly along the Chinese coast since the 1970s, and at least 512 documented HAB events have occurred from 1952 to 2002 in the Chinese mainland. It has been found that PSP and DSP toxins are distributed widely along both the northern and southern Chinese coasts. The HAB and marine algal toxin events during the 1990s in China were summarized, showing that the HAB and algal toxins resulted in great damages to local fisheries, marine culture, quality of marine environment, and human health. Therefore, to protect the coastal environment and human health, attention to HAB and marine algal toxins is urgently needed from the environmental and epidemiological view.
