AbstractFatty acids, as key components of cellular membranes and complex lipids, may play a central role in endocrine signalling and the function of adipose tissue and liver. Thus, the lipid fatty acid composition may play a role in health and disease status in the equine. This study aimed to investigate the fatty acid composition of different tissues and liver lipid classes by comparing Warmblood horses and Shetland ponies under defined conditions. We hypothesized that ponies show different lipid patterns than horses in adipose tissue, liver and plasma. Six Warmblood horses and six Shetland ponies were housed and fed under identical conditions. Tissue and blood sampling were performed following a standardized protocol. A one-step lipid extraction, methylation and trans-esterification method with subsequent gas chromatography was used to analyse the total lipid content and fatty acid profile of retroperitoneal, mesocolon and subcutaneous adipose tissue, liver and plasma. In the adipose tissues, saturated fatty acids (SFAs) and n-9 monounsaturated fatty acids (n-9 MUFAs) were most present in ponies and horses. N-6 polyunsaturated fatty acids (n-6 PUFAs), followed by SFAs, were most frequently found in liver tissue and plasma in all animals. Horses, in comparison to ponies, had significantly higher n-6 PUFA levels in all tissues and plasma. In liver tissue, horses had significantly lower hepatic iso-branched-chain fatty acids (iso-BCFAs) than ponies. The hepatic fatty acid composition of selected lipid classes was different between horses and ponies. In the polar PL fraction, horses had low n-9 MUFA and n-3 PUFA contents but higher n-6 PUFA contents than ponies. Furthermore, iso-BCFAs are absent in several hepatic lipid fractions of horses but not ponies. The differences in fatty acid lipid classes between horses and ponies provide key information on the species- and location-specific regulation of FA metabolism, thus affecting health and disease risk.

Brown alga Cystoseira barbata is the most widely distributed seaweed in the Black Sea. There is limited information about fat soluble vitamins content and fatty acids composition of this specie from Bulgarian Black Sea coast. The aim of this study was to determine fat soluble vitamins, pigments, total lipid and fatty acid composition of Cystoseira barbata. Fat soluble vitamins (vitamin E and D), pigments (β-carotene and astaxanthin) and total cholesterol were analyzed simultaneously using HPLC/UV/FL system equipped with RP analytical column. Sample preparation procedure includes alkaline saponification, followed by liquid-liquid extraction. Brown seaweed Cystoseira barbata contained high amounts of α-tocopherol and β-carotene. Lipids were extracted by following the method of Bligh and Dyer. The residual lipid fraction was methylated using base-catalyzed transmethylation with methanolic potassium hydroxide. Fatty acid composition was analyzed by GC/MS. Cystoseira barbata was rich in linoleic (C18:2n6) and eicosopentaenoic acid (C20:5n3) although total lipid content was generally low. High levels of α-tocopherol correlate with high levels of polyunsaturated fatty acids. As an antioxidant α-tocopherol preserves tissue PUFA from oxidation.

AbstractTotal lipid and the fatty acid compositions of phospholipid and triacylglycerol fractions, prepared from eggs, 3rd instars of larvae, pupae, male and female adults of Lertha sheppardi, were analyzed by gas chromatography and gas chromatography-mass spectrometry. The effect of diet (adults’ nutrition) on fatty acid composition of L. sheppardi adults was also investigated. Total lipid of L. sheppardi considerably increased in adults compared with immature stages. There was a significant decrease in total lipid level in larval stage in contrast with egg stage. Qualitative analysis revealed the presence of 14 fatty acids during all stages. The major components were C16 and C18 saturated and unsaturated components which are ubiquitous to most animal species. In addition to these components, one odd-chain (C17:0) and prostaglandin precursor fatty acids were found. The fatty acid profiles of phospholipids and triacylglycerols were substantially different. In phospholipid fraction, monounsaturated fatty acids were the major proportion of fatty acids in both sex of adults and pupae, whereas polyunsaturated fatty acids were the most dominant fatty acids in eggs and 3rd instars. Results of triacylglycerol fraction revealed that fatty acid composition of eggs had higher level of C16:1, C18:0 and C18:3n-3 content than that of 3rd instars and pupae, which suggests accumulation of energetic and structural reserve materials during embryonic development. At more advanced developmental stages, mainly in adult females, the amount of C16:1 increased once again, which may be related to the need for accumulation of sufficient energy and of carbon reservoir in the developing new vitellum. Percentages of C18:1 were significantly high in adult stages compared to other stages. These findings indicate that the accumulation and consumption of fatty acids fluctuate through different development stages. Diet did not effect the fatty acid composition of L. sheppardi adults.

Abstract. Omega-3 polyunsaturated fatty acids (PUFAs) are used for the treatment and prevention of numerous pathologies in humans. As recently found, PUFAs play significantly protective roles in liver, cardiovascular system and kidney. They also are widely used in total parenteral nutrition. We evaluated the effect of omega-3 PUFA consumption on liver fatty acid composition and the expression of CYP2E1, one of the key enzymes in detoxification and prooxidant systems of liver cells. To estimate the oxidative stress in liver tissue, the antioxidant status and the level of lipid peroxidation were determined in a rodent model. Animals were divided into two groups: control (n = 10) and experimental (n = 10). Epadol-containing omega-3 PUFA fish oil capsules were administered to Wistar rats within 4 weeks (0.1 mL/100 g b.w./day). The consumption of omega-3 PUFAs resulted in changes of fatty acid composition of liver tissue. A significant increase was detected in the α-linolenic, eicosapentaenoic and docosahexaenoic acid content (5.1-, 16-, and 1.3-fold, respectively, p < 0.05), while the content of linoleic and arachidonic acid was reduced (1.7- and 3.2-fold, respectively, p < 0.05). This caused significant increases in the omega-3:omega-6 ratio. Consumption of omega-3 PUFAs led to a 3-fold (p < 0.05) increase in CYP2E1 content, which could entail enhanced Nrf2 expression levels and increases in the HO-1 content in rat liver. The alteration in CYP2E1 expression did not have an impact on the level of lipid peroxidation and on the prooxidant/antioxidant balance.

Corrective Effect

Irrational pharmacotherapy with tetracyclines can cause mitochondrial cytopathies of liver cells and the development of toxic dystrophy. The issue of violation of the qualitative and quantitative composition of fatty acids and their functional role in the development of liver dystrophy has not been studied enough. Therefore, the aim of the work was to determine the features of changes in the fatty acid composition of blood serum and liver lipids in rats with tetracycline-induced hepatosis and the corrective efficacy of the phospholipid-acceptable dietary supplement “FLP-MD”. It was experimentally established that, in the composition of blood serum lipids and liver tissue, key changes in modeling tetracycline-induced hepatosis in rats (250 mg/kg for 7 days) are primarily tested for polyene fatty acids (PUFAs). In blood serum this is manifested by a decrease in the level of docosadiienoic (22:2ω6) and docosahexaenoic acid (22:6ω3), as well as the total PUFA content due to representatives of the ω3 family, respectively, by 1.3 times. At the same time, a decrease in the content of eicosapentenoic (20:5ω3), docosapentaenoic (22:5ω3), docosahexaenoic (22:6ω3) acids and the saturated/unsaturated fatty acid (SFA/UFA) and ω3/ω6 PUFA ratios, respectively, are noted in the lipid fraction of the liver, respectively by 1.3 times. In contrast to these animals, the use of reparative action of a phospholipid-acceptable dietary supplement “FLP-MD” (13.5 mg/kg) in sick rats provides a significant increase in the level of these fatty acids both in blood serum and in the liver and the restoration of their profile for other representatives. Thus, the components of the “FLP-MD” dietary supplement show a corrective effect on the fatty acid composition of the lipid component of blood serum and liver tissue of animals with tetracycline-induced hepatosis. Indicators have been experimentally established for the diagnosis of toxic liver damage and preclinical trials of the hepatoprotective efficacy of new drugs, which is a promising area of research in veterinary hepatopathology.

Induced Changes

Fertilized herring eggs were hatched in large sea water enclosures containing natural populations of phytoplankton and Zooplankton and the developing fish sampled at intervals for a period of 90 days to determine the levels and composition of their depot triacylglycerols. The percentage of triacylglycerols in total lipid declined from hatching to about 40 days post-hatch and then increased markedly during the remaining 50 days. During the first 30 days from hatching the acyl groups of the triacylglycerols were dominated by polyunsaturated fatty acids, especially 18:4 (n−3), 20:5 (n−3) and 22:6 (n−3), characteristic of a predominantly phytoplanktonic diet. For the remainder of the 90-day experiment the percentages of polyunsaturated fatty acids decreased, to be replaced by increasing percentages of 20:1 (n−9) and 22:1 (n−11 ) fatty acids characteristic of a predominantly zooplanktonic diet.

Iberian Pig

The fatty acid composition of total, apolar and polar lipid fractions from intra- and intermuscular fat of Iberian pig cured hams was determined. Animals were fed with diets of pasture and acorns ( montanera), acorns and cereals ( recebo) or cereals ( cebo). The major fatty acids from the total and apolar lipid fraction of Iberian pig cured ham muscular tissue were C18:1 (45-54%), C16:0 (22-26%) and C18:1 (10-13%). The same fatty acids were the major components in the total and apolar lipids from intermuscular fat of Iberian pig cured hams, with values ranging from 44 to 53% for C18:1, from 21 to 27% for C16:0 and from 10 to 14% for C18:0. In the total lipid fraction from intramus cular fat significant differences ( p ≤ 0.05) were found between all three batches in the composi tion of C18:1 and C 18:2, and between montanera and the other two batches in the fatty acids C14:0 and C16:0. For intermuscular fat, significant differences ( p ≤ 0.05) were observed between all three batches for the fatty acids C14:0, C16:0, C18:1 , C18:2 and C18:3. Although significant differences in the composition of some fatty acids of the total lipid fraction from intra- and intermuscular fat were due to the feeding system, a 100% partition among the three different diets was not obtained when stepwise discriminant analysis was applied. The results were not improved when the apolar lipid fraction was analysed.
