Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.

Example Input: Abstract: The aetiology of pain in the lower leg during exercise has been studied in 110 athletes by monitoring intracompartmental pressure during exercise and by technetium bone scans. Patients were assigned to three diagnostic groups: chronic compartment syndrome, medial tibial syndrome and those with non-specific findings. Our results indicate that subcutaneous fasciotomy of the affected compartment(s) is the treatment of choice for chronic compartment syndrome. The treatment of patients with medial tibial syndrome, either by operation or conservatively, has been unsuccessful; non-specific symptoms have been treated conservatively with success.

Example Input: Abstract: Daylength (photoperiod) influences the rate of reproductive development in the juveniles of some photoperiodic species. Recent studies show that daylength during the prenatal period is perceived by the fetus and that this perception can profoundly influence postnatal reproductive and somatic development. Using the photoperiodic Djungarian hamster, we assessed the role of the maternal pineal gland and its hormone, melatonin, in this prenatal perception of daylength. Maternal pinealectomy eliminated the influence of prenatal photoperiod on testicular and body weights of male pups, suggesting that a product from the maternal pineal gland communicates daylength to the fetus. Infusion of the pineal hormone melatonin into pinealectomized dams for various durations during gestation mimicked the effect of varying the prenatal photoperiod on both testicular and body weights. These results indicate that pineal melatonin is involved in this novel form of communication from mother to fetus.

Example Input: 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)
