Summary Lipopolysaccharides from several bacteria were selectively degraded by gut juice of the snailHelix pomatia with extensive loss of anticomplementary activity and changes in the electrophoretic pattern in polyacrylamide gels. The gut juice had little effect on ketodeoxyoctonate content or immunodominant sugars. The lipid A moiety of the lipopolysaccharide appeared to be the main site of attack. 相似文献

An interneurone, making excitatory synaptic connections with a second neurone has been identified in the brain of Helix pomatia. The results suggest that the connection is monosynaptic. 相似文献

Résumé On décrit la disposition précise des contacts synaptiques réalisée par deux gigantesques neurones contenant de la sérotonine (GSC) avec d'autre neurones dans la cervelle de l'escargotHelix pomatia. Quelques neurones sont innervés deux fois par chaque GSC. 相似文献

The distribution and characterization of MAO in various tissues of the snail were analyzed. Only low amounts of the enzyme exist in the different tissues and data suggest that there is more than one type of MAO. 相似文献

Summary Everted sacs of intestine from Helix pomatia do not actively transfer glucose, galatose, methionine, alanine, asparagine, aspartic acid or proline from the mucosal to serosal surfaces. The principal function of the intestine appears to be the reabsorption of water.The study was partly financed through a Reading University Research Board Scholarship. I thank Profs A. Graham, K. Simkiss, J. Machin and Dr C. Kyriakides for their advice and criticisms and E. Snowden and J. Counden for technical assistance. 相似文献

The present study demonstrates that the potent opiate antagonist, naloxone can selectively block the DA induced inhibition of the bursting activity pattern of the RPal or Br-type neuron. The dopamine inhibitory affect can also be blocked by haloperidol, a established dopamine receptor blocker. 相似文献
