2) The aspect of Amy’s history and physical exam that caused her doctor to pursue further tests was _____.

TreatmentRead the report and answer questions 5 and 6. Because a thymic tumor can be associated with myasthenia gravis, and its removal frequently helps to ameliorate the symptoms, Amy agreed to surgical removal of her thymus gland. Amy did not have immediate relief of her symptoms because the abnormal antibodies persist for several weeks. After almost six weeks, she regained much of strength and stamina. The pathologist’s report was also good news; Amy’s tumor was benign. Amy, however, may not be completely cured of myasthenia gravis, so she will be closely followed by her doctor. She may still require a medication that inhibits the breakdown of ACh. Medications of this type act by increasing the amount of ACh at the motor endplate and thus help sustain events of membrane depolarization. Should Amy require such a medicine, she will likely be on it the rest of her life. 5) How do medications that improve the symptoms of myasthenia gravis work?

A patient presents for sperm banking prior to cancer treatment. His sperm count is 75 million/mL, with a motility of 55%. What procedure is preferred for the cryopreservation of this specimen?
