The quantitative importance of triacylglycerol as a source of total essential fatty acids during early postnatal development is reported in the accompanying article. Our objective here was to measure the quantitative changes in individual long-chain fatty acids in specific lipid classes of the carcass, liver, and brain of the developing rat mainly to describe the relative accumulation of long-chain vs. precursor fatty acids. Fatty acids in carcass phosphatidylcholine (micrograms/g) were lower at fetal days 18-21 than at either fetal day 15 or postnatal days +3 to +9. Individual long-chain fatty acids in liver phosphatidylcholine and phosphatidylethanolamine increased markedly by day +3 postnatally, whereas in brain phosphatidylethanolamine, the postnatal increase was delayed to between days +6 and +9. Fatty acids in carcass and liver triacylglycerols increased quantitatively by 10- to 300-fold from fetal day 21 to postnatal day +3 with amounts of both arachidonic and docosahexaenoic acid equaling linoleic acid. The ratios of linoleic and alpha-linolenic acids to respective long-chain products were significantly higher in triacylglycerols, whereas that of stearic to oleic acid was higher in phospholipids. We conclude that, during early postnatal life, oleic, linoleic, and alpha-linolenic acids are required in quantitatively greater amounts in triacylglycerols, whereas stearic acid and long-chain essential fatty acids are required in phospholipids.

Abstract Eriocitrin is a citrus flavonoid with a high capacity to reduce the oxidative stress related to metabolic disorders and obesity. We assessed the effects of low doses of eriocitrin on the oxidative stress, inflammation, and metabolism of glucose and lipids of high-fat diet (HFD)-fed obese mice. Fifty male C57BL/6J mice were randomly assigned into five groups (n 10). The mice were fed an HFD (45 % kcal from fat, i.e. lard) for 4 weeks for obesity induction. After this period, the mice continued receiving the same HFD, but supplemented with eriocitrin at 10, 25 or 100 mg/kg body weight (bw) for an additional 4 weeks. Control groups were fed with standard diet (10 % kcal of fat, i.e. soy oil) or with HFD without eriocitrin, for eight consecutive weeks. At the end of the study, mice supplemented with eriocitrin showed lower levels of blood serum glucose and blood and liver triacylglycerols (P < 0⋅05). There was also improved levels of insulin, HOMA-IR, total-cholesterol, resistin and lipid peroxidation in the supplemented mice. It was concluded that the 25 mg dose of eriocitrin improved all the parameters studied and had positive effects on oxidative stress, systemic inflammation and metabolism of lipids and glucose in general.

The aim of this work was to evaluate the effect of prolonged administration of the pineal hormone melatonin and short-term fasting on metabolic variables in male and female Wistar:Han rats. Melatonin (MEL, 4 μg/ml of tap water) was administered daily since the 5th week of age. The control group drank tap water. Rats were fed a standard type of diet ad libitum and were kept in the light regimen L:D - 12:12 h. The experiment was terminated after 11 (variant B) or 12 (variant A) weeks of MEL administration. The animals were sacrificed by quick decapitation following overnight fasting (variant A) or 48-h fasting (variant B). Selected organs and tissues were removed and weighed and selected metabolic variables in the serum and tissues were determined. MEL decreased body mass independent of food and water intake in both sexes. In males (variant A) MEL increased the weight of the heart muscle, spleen and adrenals; it decreased the absolute weight of epididymal fat and increased serum corticosterone and phospholipids concentration in comparison with controls. In females, serum glucose decrease and liver triacylglycerols increase were found. After 48-h fasting (variant B) liver, spleen and adrenal weight increase in MELdrinking females was found. In males MEL increased the thymus weight and decreased the epididymal fat weight. In both sexes MEL increased serum corticosterone and liver glycogen concentration; MEL increased serum glucose in males and serum cholesterol concentration in females. Changes in the evaluated variables were also related to fasting duration prior to decapitation. A 48-h fasting at the end of the prolonged MEL intake (variant B vs. A) decreased the absolute liver weight in both sexes and the epididymal/periovarial fat weight, and increased thymus weight in males. In females it decreased the absolute heart muscle weight and increased the spleen weight. In males, 48-h fasting increased serum corticosterone and phospholipids concentration; it decreased the liver triacylglycerols content in females and the liver cholesterol content in males and females. In both sexes 48-h fasting increased glucose concentration in the serum and glycogen concentration in the liver and heart muscle as well as triacylglycerols and cholesterol concentration in the serum, phospholipids concentration in the liver and bone marrow and decreased malondialdehyde concentration in the liver. Forty-eight hour fasting after prolonged MEL administration resulted in a wider range of carbohydrate and lipid metabolism alterations of young rats of both sexes.
