Document Summary

Myasthenia gravis -a condition causing abnormal weakness of certain muscles, autoimmune disease. (antibodies shut down receptors) can you treat the patient with organophosphate insecticides- This is unethical and will cause them to twitch to death, but hypothetically it causes constant depolarization and can alleviate the symptoms b/c acetyl choline receptors are inhibited. Blood clotting- if you have a cut cell (blood clots to stop bleeding) platelets will be involved (platletes have actin which allows them to move) and start to congregate at the cut, and stick together because of hormone prostaglandin. Aspirin will acetylate the synthesizer making it inactive, so platelets will not be produced and will decrees the ability of clotting. When platelets adhere like we want them to, they create a platelet factor and calcium becomes involved, allowing for more of them to come together. Prothrombin (zymogen) if activated it makes an active protease called thrombin which is an endoprotease.
