title: [Changes in lipids of granulation fibrous tissue in rats at various doses and routes of melatonin administration].
abstract: The experimental data indicate that melatonin actively influences time-causes of changes of lipid content in rats tissue during the inflammation process. Its effect depends on a dose, modes of administration (intraperitonial, hypodermic or local) and duration of treatment. A single dose intraperitonial administration of melatonin (4 mg/kg) did not influence lipid content in the granular-fibrose tissue, while repeated injections of this hormone limited the increase in contents of lipids and phospholipids at the 5th and 8th days of regeneration. Long-term subcutaneous injections of melatonin caused distinct changes of lipids: at the dose of 0.3 mg/kg it prevented, and at the dose of 4 mg/kg it promoted the increase of lipid content in the granular-fibrose tissue. Local application of a melatonin solution (1.5 mg/ml) at early periods of regeneration caused insignificant changes of total lipids and total phospholipids in the granular-fibrose tissue. However, the higher concentration (15 mg/ml) of melatonin caused the decrease of total lipids due to reduced content of cholesterol and triglycerides and the increase of total phospholipids and some of their fractions.
