Verapamil potentiation of Chironex (box-jellyfish) antivenom.
'Rescue' experiments were performed on mice to compare the efficacy of i.v. verapamil, box-jellyfish antivenom, and a combination of both agents to counter the effects of toxic material extracted from the tentacles of Chironex fleckeri. In each of three series of experiments, four sets of mice were injected with doses of Chironex tentacle extracts containing approximately 4 mg/ml protein which ...
متن کاملEvolution and Functional Diversity of Jellyfish Opsins
Cnidaria are the most basal animal phylum possessing complex eyes [1]. Their eyes predominantly use ciliary photoreceptor cells (c-PRCs) like vertebrates, whereas insect eyes use rhabdomeric photoreceptor cells (r-PRCs) [1-4]. These two cell types show not only different cytoarchitectures but distinct phototransduction cascades, which are triggered by the respective types of opsins (e.g., [5]),...
متن کاملVisual control of steering in the box jellyfish Tripedalia cystophora.
Box jellyfish carry an elaborate visual system consisting of 24 eyes, which they use for driving a number of behaviours. However, it is not known how visual input controls the swimming behaviour. In this study we exposed the Caribbean box jellyfish Tripedalia cystophora to simple visual stimuli and recorded changes in their swimming behaviour. Animals were tethered in a small experimental chamb...
متن کامل[Marine envenomation by box-jellyfish in a tourist in Cambodia].
We report a case of box-jellyfish related envenomation in a 40 year old tourist that occurred in Sihanoukville, Cambodia, in the Gulf of Thailand. Symptoms that appeared within a few minutes associated intense pain, hand edema and large edematous and erythematous flagellations in the stung skin areas. Antibiotics and corticosteroids were delivered. Inflammatory signs and skin lesions disappeare...
متن کاملBox Jellyfish Use Terrestrial Visual Cues for Navigation
Box jellyfish have an impressive set of 24 eyes of four different types, including eyes structurally similar to those of vertebrates and cephalopods [1, 2]. However, the known visual responses are restricted to simple phototaxis, shadow responses, and object avoidance responses [3-8], and it has been a puzzle why they need such a complex set of eyes. Here we report that medusae of the box jelly...
