Owing to melatonin's antioxidant properties, the use of melatonin for the prevention of postoperative pericardial adhesion formation has been investigated. Twelve dogs received pericardial abrasions to promote adhesion and were randomized to receive either melatonin 10 mg/kg plus ethanol 5% in 10 mL sodium chloride or 10 mL sodium chloride dilution with ethanol 5%.

In mathematics, a factorial is a function applied to natural numbers greater than zero. The symbol for the factorial function is an exclamation mark after a number, like this: 2! The usual definition of ân factorialâ is ân! = n * (n â 1) * (n â 2) *â¦* 2 * 1,â where ânâ is a positive integer. The first handful of factorial values from positive integers are: 1! = 1; 2! = 2; 3! = 3*2 = 6; 4! = 4*3*2 = 24; and 5! = 5*4*3*2 = 120.
