A new disease, the slippery scar, was investigated in cultivated bags of Auricularia polytricha. This fungus was isolated from the infected mycelia of cultivated bags. Based on morphological observation, rDNA-internal transcribed spacer and 18S sequence analysis, this pathogen was identified as the Ascomycete Scytalidium lignicola. According to Koch's Postulation, the pathogenicity of S. lignic...

The ability to correlate the behaviour of neurones in intact ganglia with events in isolation as has been shown in the leech (Ready & Nicholls, 1979; Fuchs, Nicholls & Ready, 1981), may provide insight into the intrinsic properties of individual neurones. The culture of molluscan neurones is relatively new and the exact procedures for the control of environmental conditions necessary for obtain...

The suitability of neurons of the freshwater snail Lymnaea stagnalis as a test system for the neurotoxic side effects of antitumour Vinca alkaloids has been investigated, by studying the process of paracrystal induction by Vinca antitumour agents. Three Vinca alkaloids have been compared: the natural vinblastine and vincristine and the semisynthetic vindesine. They appear to induce two types of...
