A mycelial isolate of C. orellanus was obtained for the first time from an agar medium similar in composition to Pachlewski and Oddoux media. The identity of the cultures was confirmed by the chemical characterization of orellanine by tic on cellulose and photodecomposition under uv light. The orellanine content from the cultured mycelium was weaker than those from the carpophore. This result was compared with tho se obtained by other authors for the genus Amanita and Gyromitra.

High-dose chemoradiotherapy with auto-transplantation is increasingly reported and some results are encouraging. We report the results of peripheral blood stem cell transplantation (PBSCT) for multiple myeloma at a single institution over a 6-year period. Forty patients, including 18 de novo patients, received debulking chemotherapy consisting of vincristine, adriamycin, and dexamethasone or methyl-prednisolone followed by stem cell mobilization with high-dose cyclophosphamide. Twenty-nine patients received PBSCT following high-dose chemoradiotherapy. Following PBSCT 92% of evaluable patients obtained at least a partial remission and 29% reached complete remission. Objective treatment responses, defined as at least a 50% reduction in serum paraprotein or marrow plasma cells, were observed following each treatment step of debulking chemotherapy, mobilization and PBSCT in 50, 42 and 71% of patients, respectiv...

Two poplar cultivars showing different degrees of resistance to mistletoe: sensitive "Fritzi Pauley" (FPL) and resistant "Vereecken" (VER) were used. Flavonoids were detected and localized using histofluorescence after treating frozen sections with two specific reagents. Total amounts of flavonoids were determined spectrophotometrically. Defence mechanisms were induced during penetration of the primary haustorium. They consisted of inner periderm development and fiavonoid accumulation. These reactions were weaker in the FPL cultivar than in the VER one. In the latter, growth of the primary haustorium and the establishment of direct connections between the living host cells and parasite failed. The resistance of poplar cultivars to mistletoe was dependent on the production of defensive mechanisms against the pathogen.

Amanita proxima is a mushroom seldomy encountered, similar to a common and edible species: Amanita ovoïdae. During October 1992, we had the opportunity to care for five cases of intoxications with Amanita proxima. In all cases early digestive disorders, cytolytic hepatitis and acute renal failure were noted. Outcome was favourable for all patients within three weeks with total recovery of both renal and hepatic functions with symptomatic treatment. Temporary dialysis was required in four patients.

A 31-year old woman was admitted to hospital 10 days after she had deliberately ingested 2 raw carpophores of the mushroom Cortinarius orellanus. Acute renal failure (creatininaemia 1,100 mumol/l) developed, requiring 6 sessions of haemodialysis, one of plasmapheresis and the administration of diltiazem and aminoacids. Plasma and tissue assays of orellanin, the mushroom's toxin, were performed by two-dimensional thin layer chromatography. Before haemodialysis and 10 days after ingestion of the poison, the plasma contained orellanin. Eighteen months after the attempted suicide, the plasma creatinine level was 181 mumol/l.

Parasitism by this piercing-sucking insect reduced the resources for the future seedling and affected seed physiology, including dormancy and exudation of allelochemicals of imbibing seeds. Seeds attacked by H. tarsatus had reduced mass (20-80% reduction, depending on intensity of attack). Heavy attack led to irregular shape, changes in seed coat color, and disruption of dormancy. While intact seeds did not imbibe during a 48-hour test in water, a high proportion of bug-attacked seeds germinated, from 51 to 94%, depending on intensity of attack. Attack by H. tarsatus also affected accumulation of allelochemicals and their exudation by imbibing seeds. There were no quantitative differences in proanthocyanidin content between exudates of attacked and unattacked seeds. In contrast, concentrations of total condensed tannins were higher in exudates of attacked seeds on the third day of imbibition. This change may reflect induction of chemical defenses by herbivore attack and/or a mechanism to restore seed coat impermeability. Although difficult to quantify, effects of sublethal attack by this sucking insect on the seed bank are likely to have important consequences for the demography of S. drummondii, a short-lived perennial in habitats where conditions for recruitment are variable and unpredictable among years. Résumé : Les graines en développement de Sesbania drummondii sont attaquées par les nymphes et les adultes de Hyalymenus tarsatus (Hétéroptère : Alydidae), qui peut soit les détruire soit les altérer partiellement. Le parasitisme des graines par cet insecte réduit la quantité de ressources disponibles aux plantules mais influe aussi sur la physiologie des graines, comme la dormance et la production de substances allélochimiques. L'attaque des graines par H. tarsatus entraîne une réduction de leur masse (20-80 % de réduction selon le degré d'attaque). Les attaques répétées entraînent des changements dans la forme et la couleur des graines et provoquent la rupture de dormance. Alors que les graines intactes restent imperméables durant des tests d'imbibition de 48h, une grande proportion des graines attaquées germent rapidement (entre 51 et 94 % des graines, selon le degré d'attaque). Les attaques par H. tarsatus peuvent aussi affecter l'accumulation de substances allélochimiques et leur exsudation au cours de l'imbibition des graines. Il n'y a cependant pas de différence dans le contenu en proanthocyanidines entre les exsudats des graines attaquées et des graines saines. Par contre, la concentration en tannin condensés totaux est plus élevée chez les graines attaquées lors du troisième jour de l'imbibition. Ce changement dans la teneur en tanins condensés totaux peut refléter l'induction de défenses chimiques suite à l'attaque par un phytophage et / ou un mécanisme pour restaurer l'imperméabilité du tégument. Bien que difficiles à quantifier, les effets de ces attaques sublétales par des insectes suceurs sur le stock de graines au sol doivent être importants sur la démographie de S. drummondii, espèce pérenne à cycle de vie court occupant des habitats où les conditions pour le recrutement fluctuent entre années.
