Kidney toxicity and transcriptome analyses of male ICR mice acutely exposed to the mushroom toxin α-amanitin. Food Chem Toxicol 2024; 187:114622. [PMID: 38531469 DOI: 10.1016/j.fct.2024.114622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 03/20/2024] [Accepted: 03/22/2024] [Indexed: 03/28/2024]
Abstract
Amatoxins are responsible for most fatal mushroom poisoning cases, as it causes both hepatotoxicity and nephrotoxicity. However, studies on amatoxin nephrotoxicity are limited. Here, we investigated nephrotoxicity over 4 days and nephrotoxicity/hepatotoxicity over 14 days in mice. The organ weight ratio, serological indices, and tissue histology results indicated that a nephrotoxicity mouse model was established with two stages: (1) no apparent effects within 24 h; and (2) the appearance of adverse effects, with gradual worsening within 2-14 days. For each stage, the kidney transcriptome revealed patterns of differential mRNA expression and significant pathway changes, and Western blot analysis verified the expression of key proteins. Amanitin-induced nephrotoxicity was directly related to RNA polymerase II because mRNA levels decreased, RNA polymerase II-related pathways were significantly enriched at the transcription level, and RNA polymerase II protein was degraded in the early poisoning stage. In the late stage, nephrotoxicity was more severe than hepatotoxicity. This is likely associated with inflammation because inflammation-related pathways were significantly enriched and NF-κB activation was increased in the kidney.

Unraveling Hematotoxicity of α-Amanitin in Cultured Hematopoietic Cells. Toxins (Basel) 2024; 16:61. [PMID: 38276537 PMCID: PMC10820516 DOI: 10.3390/toxins16010061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 01/13/2024] [Accepted: 01/19/2024] [Indexed: 01/27/2024] Open
Abstract
Amanita phalloides poisonings account for the majority of fatal mushroom poisonings. Recently, we identified hematotoxicity as a relevant aspect of Amanita poisonings. In this study, we investigated the effects of the main toxins of Amanita phalloides, α- and β-amanitin, on hematopoietic cell viability in vitro. Hematopoietic cell lines were exposed to α-amanitin or β-amanitin for up to 72 h with or without the pan-caspase inhibitor Z-VAD(OH)-FMK, antidotes N-acetylcysteine, silibinin, and benzylpenicillin, and organic anion-transporting polypeptide 1B3 (OATP1B3) inhibitors rifampicin and cyclosporin. Cell viability was established by trypan blue exclusion, annexin V staining, and a MTS assay. Caspase-3/7 activity was determined with Caspase-Glo assay, and cleaved caspase-3 was quantified by Western analysis. Cell number and colony-forming units were quantified after exposure to α-amanitin in primary CD34+ hematopoietic stem cells. In all cell lines, α-amanitin concentration-dependently decreased viability and mitochondrial activity. β-Amanitin was less toxic, but still significantly reduced viability. α-Amanitin increased caspase-3/7 activity by 2.8-fold and cleaved caspase-3 by 2.3-fold. Z-VAD(OH)-FMK significantly reduced α-amanitin-induced toxicity. In CD34+ stem cells, α-amanitin decreased the number of colonies and cells. The antidotes and OATP1B3 inhibitors did not reverse α-amanitin-induced toxicity. In conclusion, α-amanitin induces apoptosis in hematopoietic cells via a caspase-dependent mechanism.

Abstract
Recently, mushroom poisoning is becoming one of the most serious food safety problems in China, especially in Yunnan province. However, there is insufficient information on many poisoning incidents, including mushroom information, identification and poisoning symptoms etc. In October 2022, a female midwife in Yunnan province consumed a wild mushroom twice. Detailed epidemiological investigation and mushroom identification were performed in this report. Based on morphological and phylogenetic analysis, the suspected mushroom was identified as Gymnopus dryophiloides (Omphalotaceae, Agaricomycetes). The victim reported nausea, vomiting, diarrhea, stomachache, accompanied by dizziness, headache, drowsiness, chest tightness, shortness of breath, palpitation, and weakness. The incubation period was approximately 30 min. After the victim's own vomiting, the symptoms began to subside for about an hour. Up to date, there are no detailed reports of poisoning in G. dryophiloides. In conclusion, it is the first detailed poisoning report of G. dryophiloides in the world.

Abstract
In France, mushroom picking is part of the culture. The practice is not without risk, as around 1300 people are poisoned each year by eating wild mushrooms on the French mainland. However, this practice is not part of local culture on Reunion Island, a French territory located in the Indian Ocean. Indeed, there are practically no reports of mushroom poisoning on Reunion Island. Here we describe, through a retrospective study, cases of mushroom poisoning recorded in the Indian Ocean toxicosurveillance system database from 2020 to 2021. Overall, 19 people were poisoned following wild mushroom ingestion on Reunion Island: 15 in 2020 and 4 in 2021. Six events were recorded: the majority of poisonings involved clusters (n = 5) during a shared meal (pan-fried), only one case was single mushroom poisoning by ingesting a raw mushroom. Of all patients, 15 cases presented a gastrointestinal irritant syndrome (latency between 30 min and 3 h). Chlorophyllum molybdites was positively identified by mycologists in 4 cases, suspected by emergency doctor in 1 case and in one self-declared case, Volvariella volvacea was consumed. Poisoning following ingestion of wild mushrooms does occur on Reunion Island, and Chlorophyllum molybdites is the main culprit.

Antidotal effect of cyclosporine A against α-amanitin toxicity in CD-1 mice, at clinical relevant doses. Food Chem Toxicol 2022; 166:113198.

Abstract
Amanita phalloides is one of the most toxic mushrooms worldwide, being responsible for the majority of human fatal cases of mushroom intoxications. α-Amanitin, the most deleterious toxin of A. phalloides, inhibits RNA polymerase II (RNAP II), causing hepatic and renal failure. Herein, we used cyclosporine A after it showed potential to displace RNAP II α-amanitin in silico. That potential was not confirmed either by the incorporation of ethynyl-UTP or by the monitoring of fluorescent RNAP II levels. Nevertheless, concomitant incubation of cyclosporine A with α-amanitin, for a short period, provided significant protection against its toxicity in differentiated HepaRG cells. In mice, the concomitant administration of α-amanitin [0.45 mg/kg intraperitoneal (i.p.)] with cyclosporine A (10 mg/kg i.p. plus 2 × 10 mg/kg cyclosporine A i.p. at 8 and 12 h post α-amanitin) resulted in the full survival of α-amanitin-intoxicated mice, up to 30 days after the toxin's administration. Since α-amanitin is a substrate of the organic-anion-transporting polypeptide 1B3 and cyclosporine A inhibits this transporter and is a potent anti-inflammatory agent, we hypothesize that these mechanisms are responsible for the protection observed. These results indicate a potential antidotal effect of cyclosporine A, and its safety profile advocates for its use at an early stage of α-amanitin intoxications.

Abstract
About 95% of fatal mushroom poisonings worldwide are caused by amatoxins and phallotoxins mostly produced by species of Amanita, Galerina, and Lepiota. The genus Lepiota is supposed to include a high number of species producing amatoxins. In this study, we investigated 16 species of Lepiota based on 48 recently collected specimens for the presence of amatoxins by liquid chromatography coupled to a diode-array detector and mass spectrometry (UHPLC-QTOF-MS/MS). By comparing the retention times, UV absorptions, and diagnostic MS fragment ions with data obtained from the benchmark species Amanita phalloides, we detected α-amanitin and γ-amanitin in Lepiota subincarnata, α-amanitin and amaninamide in Lepiota brunneoincarnata, and β-amanitin and α-amanitin in Lepiota elaiophylla. Phallotoxins have not been detected any of these species. Two possibly undescribed amatoxin derivatives were found in Lepiota boudieri and L. elaiophylla, as well as one further non-amatoxin compound in one specimen of L. cf. boudieri. These compounds might be used to differentiate L. elaiophylla from L. xanthophylla and species within the L. boudieri species complex. No amatoxins were detected in L. aspera, L. castanea, L. clypeolaria, L. cristata, L. erminea, L. felina, L. fuscovinacea, L. lilacea, L. magnispora, L. oreadiformis, L. pseudolilacea, L. sp. (SeSa 5), and L. subalba. By combining the occurrence data of amatoxins with a phylogenetic analysis, a monophyletic group of amatoxin containing species of Lepiota is evident. These chemotaxonomic results highlight the relevance of systematic relationships for the occurrence of amatoxins and expand our knowledge about the toxicity of species of Lepiota.

Abstract
Recently, consumption of the gyromitrin-containing neurotoxic mushroom Gyromitra sp. (false morel), as gourmet food was hypothesized to play a role in sporadic amyotrophic lateral sclerosis genesis. The present review analyses recent data on edibility and toxicity of false and true morels and Agaricus spp. Controversy about the toxic status of Gyromitra esculenta was due to variable toxin susceptibility within consumers. We suggest that Verpa bohemica, another false morel, is also inedible. We found a temporary neurological syndrome (NS) with cerebellar signs associated with high consumption of fresh or dried true morels Morchella sp. After ingestion of crude or poorly cooked fresh or dried morels, a gastrointestinal “haemolytic” syndrome was also observed. Agaritine, a water soluble hydrazinic toxin closely related to gyromitrin is present along with metabolites including diazonium ions and free radicals, in Agaricus spp. and A. bisporus, the button mushroom, and in mice after ingestion. It is a potential weak carcinogen in mice, but although no data are available for humans, a lifetime low cumulative extra cancer risk in humans can be estimated to be about 10−5. To conclude, a safety measure is to avoid consuming any true morels or button mushrooms when crude or poorly cooked, fresh or dried.

Abstract
OBJECTIVE To find out the clinical indicators related to prognosis in patients with acute mushroom poisoning, and approach its correlation with prognosis. METHODS Clinical data of patients with mushroom poisoning admitted to the First Hospital of China Medical University, the Ninth People's Hospital of Shenyang, Xiuyan Central People's Hospital, and Fushun Central Hospital from August 2015 to August 2017 were retrospectively analyzed. The biochemical indicators within 24 hours after admission, sequential organ failure assessment (SOFA) score, model for end-stage liver disease (MELD) score, whether plasmapheresis (PE) was carried out or not and 28-day prognosis of patients were collected. According to prognosis, the patients were divided into death group and survival group, and the differences in above parameters between the two groups were compared. Spearman or Pearson correlation method was used to analyze the relationship between MELD score and prognosis. Receiver operating characteristic (ROC) curve was used to analyze the prognostic value of MELD score for prognosis. Further analysis of the patients receiving PE treatment was conducted. RESULTS A total of four Liaoning hospitals with 89 patients with mushroom poisoning were enrolled, with 6 died within 28 days, and 83 survived. There were 17 patients with severely impaired liver and coagulant functions accepted PE treatment, with 6 patients died within 28 days, and 11 survived. (1) In 89 patients, compared with survival group, MELD score, prothrombin time (PT), activated partial thromboplastin time (APTT), total bilirubin (TBil), international normalized ratio (INR), blood glucose (Glu), alanine aminotransferase (ALT), γ-glutamyltransferase (GGT) in death group were significantly increased [MELD score: 32.34 (28.31, 41.06) vs. 8.76 (3.77, 21.19), PT (s): 53.5 (52.4, 113.2) vs. 14.5 (13.8, 19.5), APTT (s): 58.6 (48.9, 70.8) vs. 36.9 (34.4, 43.2), TBil (μmol/L): 134.8 (31.3, 155.6) vs. 21.5 (15.1, 41.4), INR: 6.0 (5.6, 14.7) vs. 1.2 (1.1, 1.5), Glu (mmol/L): 9.2 (9.0, 11.0) vs. 6.6 (5.7, 7.8), ALT (U/L): 5 923.0 (1 105.0, 6 000.0) vs. 35.0 (18.0, 1 767.0), GGT (U/L): 49.0 (32.0, 57.0) vs. 25.0 (16.0, 41.0), all P < 0.05], but the prothrombin activity (PTA), albumin (ALB), serum Na+, Cl- were significantly decreased [PTA: 13.0% (6.0%, 14.0%) vs. 80.0% (61.0%, 87.0%), ALB (g/L): 31.1 (29.8, 39.0) vs. 42.4 (37.9, 44.3), Na+ (mmol/L): 126.5 (122.4, 131.0) vs. 137.0 (134.9, 141.0), Cl- (mmol/L): 93.5 (87.6, 95.0) vs. 104.0 (101.3, 106.0), all P < 0.05]. Spearson correlation analysis showed that MELD score of patients with mushroom poisoning was positively correlated with the 28-day mortality (r = 0.423, P = 0.001). ROC curve analysis showed that the area under ROC curve (AUC) of MELD score for prognosis of patients with mushroom poisoning was 0.926; when the cut-off value was 27.30, the sensitivity was 100%, and the specificity was 84.3%. (2) In 17 patients who accepted PE treatment, compared with survival group, the MELD score, TBil, Glu, and ALT in the death group were significantly increased [MELD score: 36.81±5.18 vs. 29.01±5.23, TBil (μmol/L): 145.2±13.9 vs. 93.2±44.0, Glu (mmol/L): 9.1±1.9 vs. 6.0±2.7, ALT (U/L): 5 961.5±44.5 vs. 3 932.9±1 625.7, all P < 0.05], and Cl- was significantly lowered (mmol/L: 94.3±1.2 vs. 100.5±5.7, P < 0.05), but SOFA score showed no significant difference (5.83±2.71 vs. 5.91±1.58, P > 0.05). Correlation analysis showed that the MELD score in patients with mushroom poisoning who accepted PE treatment was positively correlated with 28-day mortality (r = 0.355, P = 0.001), but no correlation with SOFA score was found (r = 0.427, P = 0.087). ROC curve analysis showed that the AUC of MELD score in the prediction of mushroom poisoning patients undergoing PE treatment was 0.545; when the cut-off value was 32.19, the sensitivity was 33.3%, and the specificity was 100%. CONCLUSIONS In mushroom poisoning patients, especially those undergoing PE treatment, the higher the MELD score, the higher the mortality is. MELD score could assess the prognosis of patients with acute mushroom poisoning.

Abstract
BACKGROUND As the currently known diagnostic DNA targets amplified in the PCR assays for detection of poisonous mushrooms have their counterparts in edible species, there is a need to design PCR primers specific to the genes encoding amanitins and phallotoxins, which occur only in poisonous mushrooms. OBJECTIVE The aim of the study was testing of PCR-based method for detection of all genes encoding hepatotoxic cyclic peptides - amanitins and phallotoxins present in the most dangerous poisonous mushrooms. MATERIAL AND METHODS Degenerate primers in the PCR were designed on the basis of amanitins (n=13) and phallotoxins (n=5) genes in 18 species of poisonous mushrooms deposited to Genbank of the National Center for Biotechnology Information. RESULTS The specificity of the PCR assays was confirmed against 9 species of edible mushrooms, death cap - Amanita phalloides and panther cap - Amanita pantherina. CONCLUSIONS Designed two couples of PCR-primers specific to amanitins and phallotoxins genes can be recommended for detection of Amanita phalloides and other mushroom species producing hepatotoxic cyclic peptides - amanitins and phallotoxins.

Abstract
BACKGROUND/AIM Alpha- and beta-amanitins are the main toxins of the poisonous Amanita phalloides mushroom. Although there are many studies available concerning alpha-amanitin, there are limited data about beta-amanitin in the literature. Therefore, this study is aimed at comparing the toxic effects of alpha- and beta-amanitin on the MCF-7 cell line. MATERIALS AND METHODS The alpha- and beta-amanitins used for this research were purified from Amanita phalloides by preparative high-performance liquid chromatography. The MCF-7 breast cancer cell line was used, and specific concentrations of the toxins (100, 10, 1, 0.1, and 0.01 μg/mL) were applied to the cells. The MTT test was performed to determine the level of toxicity, and the quantity of protein in the cell was measured using the biuret test. RESULTS The aLpha-amanitin showed a higher toxicity at 36 h, while the highest inhibition of protein synthesis by the beta-amanitin was observed at 24 h. CONCLUSION It was shown that the beta-amanitin may be responsible for toxicity, like alpha-amanitin, in Amanita phalloides mushroom poisoning. The early inhibition of protein synthesis for beta-amanitin might be useful for future experiments and research.

Abstract
In Facultad de Ciencias Exactas y Naturales,Universidad de Buenos Aires there is a service called Servicio de Identificación de Hongos Tóxicos, directed by researchers of the Program of Medicinal Plants and Fungi Involved in Biological Degradation (PROPLAME-PRHIDEB, CONICET) that assist hospitals and other health establishments, identifying the different samples of fungi and providing information about their toxicity, so that patients can receive the correct treatment. The objective of the present study was to analyze all the cases received from 1985 to 2012. This analysis permitted the confection of a table identifying the most common toxic species. The information gathered revealed that 47% of the patients were under 18 years of age and had eaten basidiomes; the remaining 53% were adults who insisted that they were able to distinguish edible from toxic mushrooms. Chlorophyllum molybdites turned out to be the main cause of fungal intoxication in Buenos Aires, which is commonly confused with Macrolepiota procera, an edible mushroom. In the second place Amanita phalloides was registered, an agaric known to cause severe symptoms after a long period of latency (6-10 hours), and which can lead to hepatic failure even requiring a transplant to prevent severe internal injuries or even death, is not early and correctly treated.

Abstract
The mushroom genus Amanita has a spectrum of chemical compounds affecting survival and performance of animals. Ibotenic acid is one of such compounds found in some Amanita mushrooms. We studied the effects of ibotenic acid and its derivative, muscimol, on egg-to-pupa survival, pupation time, and pupal size in five Drosophila species (Diptera: Drosophilidae), Drosophila bizonata, Drosophila angularis, Drosophila brachynephros, Drosophila immigrans, and Drosophila melanogaster. The first three species are mycophagous and use a wide range of mushrooms for breeding, whereas D. immigrans and D. melanogaster are frugivorous. We reared fly larvae on artificial medium with 500, 250, 125, and 62.5 microg/ml of ibotenic acid and/or musimol. The three mycophagous species were not susceptible to ibotenic acid, whereas the two frugivorous species were affected. In experiments with D. melanogaster, muscimol was less toxic than ibotenic acid.

Abstract
An analysis of patients with mushroom poisoning hospitalized in the Clinic of Toxicology in Cracow revealed that only a small percentage of cases had been caused by the death cap Amanita phalloides (Vaill. ex Fr.) Secr. The most important factors contributing to intoxication are confusion of toxic mushrooms with edible species, and non-specific mushroom poisoning. The genus Amanita has a global distribution and is one of the most well-known genera of macrofungi. Active toxins present in the panther cap (A. pantherina) (DC ex Fr.) Secr are ibotenic acid and muscimol, which are rapidly absorbed from the gastrointestinal tract. It is likely that other substances also participate in the psychotropic effects. Five frayed panther cap fruiting bodies were eaten by mistake by two persons (27 and 47 years of age). Symptoms onset occurred after 120 min with central nervous system (CNS) depression, ataxia, waxing and waning obtundation, religious hallucinations and hyperkinetic behaviour. In the present case, successful general symptomatic treatment was administered, which consisted of controlling the nervous symptoms and stabilizing the electrolyte balance. The poisoning regressed with no organ complications.

Abstract
BACKGROUND The etiology of encephalopathy in uremic patients is multiple. We recently encountered a novel type of encephalopathy which occurred exclusively in patients with chronic kidney diseases after ingestion of a mushroom called Sugihiratake. While the exact etiology of this encephalopathy remained mysterious, we aimed to describe its clinical features. METHODS A total of 32 patients with chronic kidney diseases who had presented with encephalopathy following ingestion of Sugihiratake were enrolled from seven prefectures in Japan., with 24 of the 32 patients undergoing regular hemodialysis. The patient's clinical data were from surveillance by The Japanese Society of Nephrology. RESULTS There was a significant association between Sugihiratake ingestion and the occurrence of encephalopathy in 524 hemodialysis patients questioned for a recent ingestion of this mushroom (P= 0.0006). The latent asymptomatic period before the onset of symptoms varied from 1 to 31 days (mean 9.1 +/- 7.3) days. The patient's symptoms consisted of disturbed consciousness in 30 patients (93.8%), convulsions in 25 (78.1%), myoclonus in 15 (46.9%), dysarthria in ten (31.3%), ataxia in eight (25.0%), paresis or paralysis in seven (21.9%), and skin parasthesia in two patients (6.3%). Nine (27.2%) patients died, mostly due to respiratory failure. The other patients were either discharged or still in hospitals with various degrees of clinical improvement. CONCLUSION Patients with chronic kidney diseases are at risk of having serious encephalopathy following Sugihiratake ingestion and must refrain from eating it. Physicians, in those parts of the world, where this mushroom harvesting is common, should be aware of this complication.

Abstract
Gathering and eating mushrooms and other plants containing psychoactive substances has become increasingly popular among young people experimenting with drugs. Dried fly agaric Amanita muscaria fruiting bodies were eaten by five young persons (18-21 years of age) at a party in order to evoke hallucinations. Visual and auditory hallucinations occurred in four of them, whereas a 18-year-old girl lost consciousness. The following morning, she went to the Clinic of Toxicology. Due to the fact that not all the active substances present in the fly agaric have been identified, and some of them have an effect after a period of latency, the patient was admitted for several days of observation during which check-up examinations were performed. After four days without any problems, she was discharged. The poisoning regressed with no organ complications. The remaining persons who had eaten the fly agaric were free from any complaints.

Abstract
BACKGROUND/AIMS Indication of liver transplantation in acute liver failure following amatoxin intoxication is still uncertain. METHODS One hundred and ninety-eight patients were studied retrospectively. The laboratory parameters alanine-aminotransferase, serum bilirubin, serum creatinine and prothrombin index were analyzed over time. Predictors of fatal outcome and survival were determined by receiver-operating-characteristic and sensitivity-specificity analysis. RESULTS Twenty-three patients died in the median 6.1 days (range, 2.7-13.9 days) after ingestion. Using a single parameter as predictor of fatal outcome the area under the receiver-operating-characteristic curve of prothrombin index (0.96) and serum creatinine (0.93) were both significantly greater (P<0.05) compared with serum bilirubin (0.82) and alanine-aminotransferase (0.69). Prediction of fatal outcome had an optimum, if a prothrombin index less than 25% was combined with a serum creatinine greater than 106 micromol/l from day 3 after ingestion onwards (sensitivity 100%, 95% confidence interval 87-100; specificity 98%, 95% confidence interval 94-100). The median time period between the first occurrence of this predictor in non-survivors and death was 63h (range, 3-230h). CONCLUSIONS A decision model of liver transplantation following amatoxin intoxication using prothrombin index in combination with serum creatinine from day 3 to 10 after ingestion enables an early and reliable assessment of outcome.

Abstract
The enzymatic investigations were done in 56 patients, including 30 females and 26 males in the age range 18-76 (mean 52 +/- 12). Thirty two of them (57.1%) suffered from type 2 diabetes. All the patients consumed voluntarily Tricholoma equestre; 43 of them only once from 70 to 150 g, and 13 patients from two to four times for 4 consecutive days (between 300 g and 1200 g). Twenty seven patients, because of hyperlipidemia, took statins (simvastatin á 20 mg--15 patients, lovastatin á 20 mg--6 patients, fluvastatin á 80 mg--3 patients, atorvastatin á 20 mg--3 patients) and seven took fibrates (4 patients-- enofibrate á 267 mg, and 3 patients--ciprofibrate á 100 mg). Two subjects ingested both simvastatin á 20 mg and fenofibrate á 267 mg. Three to six days after the last mushroom dish, blood samples were taken from patients to examine the serum creatine kinase (CK), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities. The biochemical analyses were performed by means of the kinetic spectrophotometry using the autoanalyzer Architect ClI8200 with Abbott proprietary reagents. Statistical analysis was performed by means of t-Student test. Tricholoma equestre taken by patients in a total amount from 70 g to 1200 g for four consecutive days did not cause the significant increase in serum CK, AST, ALT activities. Similar mushroom dishes consumed by patients constantly using statins or fibrates also did not increase significantly the serum CK, AST, ALT activities. Patients treated with statins or fibrates may eat Tricholoma equestre in reasonable amount according to the established tradition.

Abstract
UNLABELLED Toxic induced hypoglycemia is usually caused by the anti-diabetic treatment and excessive alcohol consume. Hypoglycemia in diabetics treated with insulin or anti-diabetic oral agents is far the most studied form of hypoglycemia. Less information is available on toxic-induced hypoglycemia in non-diabetic subjects with acute exogenous poisoning. MATERIAL AND METHODS We retrospectively studied adult non-diabetic patients admitted in Emergency Clinic Hospital of Iaşi with hypoglycemia caused by an acute poisoning, over a period of 10 years. Then we performed a prospective study in those poisoning associated with hypoglycemic risk, to assess the prevalence of toxic-induced hypoglycemia. RESULTS We identified 15,497 patients with acute poisoning in our retrospective study, 4,005 of whom presented poisoning associated with hypoglycemic risk (40% acute ethanol poisoning, 29% wild mushroom poisoning, 23% beta-blocker poisoning, 7% salicylate poisoning and 1% patients with anti-diabetic agents acute poisoning). The prospective study identified 1,034 patients with acute poisoning, 20.11% of whom had ethanol poisoning, 11.79% had beta-blocker poisoning, 5.89% had wild mushroom poisoning, 1.74% had salicylate poisoning and the rest of 60.47% had other acute poisoning, without hypoglycemic risk. Attempted suicide with anti-diabetic agents in non-diabetic subjects produced the most severe and prolonged form of hypoglycemia in acute poisoning. 23 patients in retrospective study and 6 patients in prospective study died, but in only one situation, the death was the direct consequence of hypoglycemia. CONCLUSIONS In non-diabetic subjects with acute poisoning, prevalence of toxic-induced hypoglycemia depends on the poison itself, the mechanism of poisoning, also depends on the association between toxics and the severity of toxic- induced liver disease. A useful test to assess toxic-induced hypoglycemia is standard 6 hour oral glucose tolerance test (OGTT). Factors predicting a negative outcome in toxic-induced hypoglycemia are association of toxins, cardiac and hepatic complications, and age (>65 years).

Abstract
UNLABELLED Animal toxicity study of Tricholoma equestre mushrooms stored for 12 months at (-)20 degrees C was performed using 30 male BALB/c mice. Three groups of 5 mice each were given suspension of T. equestre powder in water, boiled aqueous extract and chloroform-methanol extract dissolved in Miglyol 812 by gavage for three consecutive days. Mice in control groups were given water, Miglyol 812 and p-phenylenediamine (CAS 106-50-3). Creatine kinase activity was determined in serum collected 72 hours after the final dose. Mean activity of serum creatine kinase in mice treated with T. equestre powder, aqueous extract, chloroform-methanol extract and Miglyol 812 were 157 +/- 93, 129 +/- 30, 96 +/- 38, 111 +/- 66 U/L respectively and did not differ significantly from mean activity in mice which were given water (107 +/- 38 U/L). Mean serum creatine kinase activity in p-phenylenediamine group (265 +/- 63 U/L) was significantly higher than in group treated with water (p<0.01). CONCLUSION Extracts of Tricholoma equestre mushrooms stored for 12 months at (-)20 degrees C did not cause rhabdomyolysis in male BALB/c mice.

Abstract
Psychoactive mushrooms ("magic mushrooms") have been consumed in northern Europe since the late seventies. Recently, the use of hallucinogenic fungi has become popular among young people again. In autumn, psychoactive mushrooms can be collected from their natural habitats throughout Europe. Some species are cultivated in the Netherlands and are sold in "smart-shops" or via Internet. In Germany, dried specimens are sold as "Duftkissen" (aroma pads). The article reviews the common psychoactive species and illustrates medical risks.

Abstract
Among young patients with multiple substance abuse, a high level of abuse of natural products was noticed. In a rehabilitation clinic for young addicts 180 patients filled out a questionnaire regarding drugs they regularly consumed. It was discovered that the patients consumed high levels of Psilocybe, Amanita and Datura. The natural drugs of the 70's, Ayahuasco and Cactus, are now rarely seen. The toxicological basis of the frequently used biological drugs is discussed. The results imply that a specific exploration of patients with multiple substance abuse in regard to the use of biological drugs is necessary.

Abstract
Some toxins do not result in clinical manifestations until several hours after exposure. This article reviews those agents that may cause delayed-onset toxicity. They are organized into four classes: specific pharmaceuticals, biologicals, pharmaceutical dosage forms, and chemicals. There are five basic mechanisms for delayed toxicity: delayed absorption, distribution factors, metabolic factors, cellular and organ capacity effects, and unknown. Scientific evidence for delayed-onset of effects varies considerably among the individual toxins.

Abstract
Finns have adopted two traditions of mushroom use: one, the old Roman tradition, came through France and Sweden to the educated, mostly Swedish speaking people of southwest Finland; the other came from the east via Karelia and was adopted by ordinary country folk. This eastern tradition is still maintained among the Karelinas living in Tver government in Russia. Even the use of Amanita muscaria for killing flies is still utilized there. The western tradition favoured chanterelles and Boletus edulis, the eastern acrid milk caps, the Lactarius species. During the famines in the 1860's and after the World War II the government authorities tried to promote the use of wild mushrooms, but the real impulse to a more versatile mushroom use was initiated after the war when 400,000 evacuees from that part of Karelia conquered by the Soviet Union were resettled among farming families all over Finland. In 1969 the National Board of Forestry began to train mushroom advisors, a programme which still continues. In 1981 Finland passed a statute on edible mushrooms and drew up a list of commercial species. Even today the largest percentage of marketed mushrooms comes from Eastern Finland and the Lactarius tivialis species sells best. Gyromitra esculenta, the false morel is considered a delicacy. Today picking mushrooms is a passionate hobby for many Finns.

Abstract
Three metabolites, tentatively named HS-A, -B and -C, were isolated from a mushroom, Hebeloma spoliatum, as the fatal toxic principles to mice. HS-A was identified as 3-acetyl-2-(3'-hydroxy-3'-methyl)glutarylcrustulinol, which has been isolated from Hebeloma crustuliniforme and H. sinapizans as a cytotoxic principle. HS-B and -C were deduced to be 3,21-diacetyl-2-(3'-hydroxy-3'-methyl)glutarylcrustulinol and 3-acetyl-2-(3'-hydroxy-3'-methyl)glutarylanhydrocrustulinol, respectively, from their chemical and spectral data. Intraperitoneal administration of HS-A, -B and -C at a dose of 100 mg/kg caused death after paralysis of the limbs in mice. The compounds caused relaxation of mouse small intestine contracted by acetylcholine chloride or barium chloride treatment in vitro. They appear to exhibit a papaverine-like relaxation effect.
