Phospholipid composition of granulation and fibrous tissues in rats after local application of melatonin

We studied the effect of melatonin applied locally in doses of 1.5 and 15 mg/ml on the phospholipid composition of granulation and fibrous tissues in rats at various stages of regeneration. Melatonin (especially in a dose of 1.5 mg/ml) increased the total phospholipid content on day 8 of regeneration, which was primarily related to accumulation of ethanolamine- and serine-containing fractions. Melatonin in a dose of 15 mg/ml increased the concentration of choline-containing fractions on day 5 of regeneration.
