Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Q: Abstract: In summary, we present a 30-year follow-up of injected wax for the prevention of male-pattern baldness. Removal was precipitated by the presence of a fibroxanthoma of the scalp. No other scalp lesions were found, nor were there any manifestations of an autoimmune disease. The injected wax failed to prevent androgenic alopecia and created a remodeling of the outer table of the cortex of the skull.
Which is the apt title for the abstract? option1: A 30-year follow-up of wax injection for the prevention of androgenic alopecia. option2: Comparison of nasal and tracheobronchial clearance by similar techniques in normal subjects.

Q: Abstract: To investigate the mechanism of ventricular arrhythmias induced by epinephrine in dogs with hypokalemia, 30 adult mongrel dogs were separated into a control group (n = 13) and a hypokalemia group (n = 17). In the hypokalemia group, sodium polystyrene sulfonate (5 g/kg body weight) was infused into the colon. In both groups, the serum concentrations of sodium, potassium and calcium were measured every 15 minutes for 60 minutes. The mean (+/- standard deviation) serum potassium level of the hypokalemia group decreased significantly from 3.81 +/- 0.21 to 2.92 +/- 0.36 mEq/liter; there were no significant changes in other electrolytes. After 60 minutes, epinephrine (10 micrograms/kg) was injected intravenously in the hypokalemia and control groups, and the arrhythmia ratio (the number of ventricular ectopic beats divided by the total heart rate) was calculated for 5 minutes. Each group was further classified into subgroups of dogs with an arrhythmia ratio higher or lower than 10%. An arrhythmia ratio over 10% was observed in 7.7% of the control group and 53% of the hypokalemia group. Immediately after 5 minutes of epinephrine injection, myocardial mitochondria and plasma membrane fraction were prepared from each group. Mitochondrial calcium content and phospholipase activity of plasma membrane fraction were determined. Significant increases in both mitochondrial calcium content and phospholipase activity were observed in the dogs with hypokalemia and an arrhythmia ratio greater than 10%.(ABSTRACT TRUNCATED AT 250 WORDS)

Q: Abstract: Light and electron microscopy were used to demonstrate extensive matrix degradation in a failed chymopapain-treated disc as compared with an untreated degenerative control disc. Both specimens contained viable cells with patches of degenerative cells. There was a loss of disc height in the chymopapain-treated disc, but no improvement of symptoms. These results illustrated that even in well-circumscribed cases with documented disc protrusion into the spinal canal, the disc space narrowing following injection may aggravate the symptoms of nerve root entrapment, especially if a low-grade lateral recess stenosis is associated with the disc protrusion. The persistence or aggravation of symptoms probably is related to these anatomic considerations. The low level of enzyme activity in the injected area may or may not be correlated with the clinical response to treatment.
