| This paper presents a short summary of the knowledge on marine biotoxins. As toxins are known for their acute effects, they have been classified here according to the effects they cause in acute human poisoning incidents. Toxins may thus be distinguished into those that affect the nervous system (paralytic and other neurotoxins), memory (amnesic poisons), and the digestive system (diarrhetic toxins). Furthermore, newly emerging toxins, such as ciguatoxins or shark toxins, and factors that lead to the introduction of toxins in new areas, are presented. Relevant suggestions for further reading are given. |

| As neuronastrocyte interactions play a crucial role in the adult brain, it is thought that astrocytes support learning and memory through specific mechanisms. In this study, the effect of scopolamine based amnesia on the number of astrocytes in rats' hippocampus was studied. Adult male albino Wistar rats were bilaterally cannulated into the CA1 region and animals received saline or different doses of scopolamine (0.5, 1 and 2 mg/ rat, intra - CA1), immediately after training. Then all the rats were sacrificed and coronal sections were taken from the dorsal hippocampal formation of the right cerebral hemispheres and stained with PTAH. The area densities of the astrocytes in dentate gyrus were measured and compared in the all groups (p < 0.05). Data... |
