Identification of Pelargonium radula as bioindicator for mercury (Hg) detection confers a new hope for monitoring the safety of drinking water consumption. Hg, like other non-essential metals, inflicts the deterioration of biological functions in human and other creatures. In the present study,
Investigations have been carried out on the long-term effect of a single whole body X-irradiation on radula, radula replacement rate, and radular gland ofLimax flavus L. 1. Damage in the radula. In the course of 8 weeks after irradiation with 50 000 R two separate damaged areas develop in the
On the basis of the distribution of NADPH-diaphorase (NADPH-d) activity, we have previously suggested a role for nitric oxide (NO) in the development of Lymnaea stagnalis. In the present study, the long-term effects of NO donors (sodium nitroprusside, S-nitroso-N-acetyl-penicillamine) and nitric
1. We studied regeneration of neuromuscular connections by identified buccal motoneuron B15 after axotomy produced by crushing nerve 4; the intact contralateral nerve 4 served as control. Electrophysiological recordings, intracellular dye injections, and light and electron microscopy were used to
