Dinner 3

Despite the last two cases, you're still eating fish for dinner. This time, on a trip to Japan, you try a local delicacy. Within minutes of eating the dish above, you note weakness, dizziness, paresthesias of the face and extremities, and nausea. Since you always carry around a trusty reflex hammer, you test your reflexes and find they're absent. The fear with this disease is paralysis and hypotension. The toxin is shown below. Cool ring structure!
Challenge: What's your diagnosis?

Dinner 3

Pufferfish poisoning is due to tetrodotoxin which concentrates in the liver, visceral organs, and skin of the fish. It binds sodium channels to prevent sodium influx into nerve axons.
