Amatoxins are one of the most potent toxins that cause hepatic and renal failure. However, this is the first report demonstrating an elevation of cardiac enzymes in a patient with Amanita phalloides poisoning. A 56-year-old male was admitted to the emergency department (ED) 42 h after an unknown type of mushroom ingestion. Hepatic, renal function tests, amylase and cardiac enzymes (troponin I, creatine kinase (CK), CK-MB isoenzyme and myoglobin) were found elevated in his blood chemistry. The electrocardiogram disclosed sinus tachycardia. Aggressive treatment with fluids, activated charcoal, penicillin G and silibinin were started. The patient was sent to hemodialysis because of anuria. During follow-up, biochemical parameters and clinical findings improved. The patient was discharged from the hospital following the arrangement of hemodialysis schedule because of the chronic renal failure. False elevations of cardiac markers may confuse the clinicians in differantial diagnosis of myocardial infarction in ED. In our patient, amatoxins that have bound the actin filaments within myocardiocytes or renal cells and/or its effects as circulating anti-troponin antibodies might result in elevation of cardiac markers. Elevated cardiac enzyme levels without any acute coronary syndrome are probable in mushroom poisoning cases involving amatoxin ingestion. Human & Experimental Toxicology (2007) 26, 757— 761

Effects of Some Beneficial Bacteria in Casing Soil on Growth and Yield of Cultivated Mushroom Agaricus bisporus A R T I C L E I N F O A B S T R A C TThis research was carried out to determine the interaction between some bacteria naturally existing in casing soil and Agaricus bisporus (Sylvan Hauser A15) hypha in laboratory (in vitro) and cultivation (in vivo) conditions, and to confirm its effects on mushroom yield. Totally 32 bacteria (3 Gram (+) and 29 Fluorescent Pseudomonads) was isolated from casing soil and healthy sporophores. As a result of in vitro experiment carried out to determine the effects of bacteria on mycelium growth of A. bisporus, 24 bacterial isolates were found more effective at the rate of 2 to 115% than control treatment. To determine the effects of bacterium, chosen at the end of in vitro experiments, on mushroom yield in cultivation conditions, three experiments were established in March, May and July in 2008. At the end of experiments, bacterial isolates provided 8 -40 % increase in total yield. Population density and change in population number related to time was observed during growing period, after the inoculation of bacterial isolates into casing soil. According to the results, Pseudomonas fluorescens (T 4/2 and Ş 8), P.putida (Ş 2/1 and Ş 10) and Bacillus mycoides (T 7/2) bacterial isolates were colonized successfully both in casing soil and sporophores.
