Probiotics could represent an effective alternative to the use of synthetic substances in nutrition and medicine. The data concerning the efficacy of probiotics are often contradictory. This paper focuses on the enhancement of the efficacy of probiotics by their combination with synergistically acting components of natural origin. Maltodextrins can be obtained by enzymatic hydrolysis of starch and are suitable for consumption. Administration ofLactobacillus paracaseitogether with maltodextrin decreased the number ofEscherichia colicolonising the jejunal mucosa of gnotobiotic piglets by 1 logarithm compared to the control group. Fructo-oligosaccharides (FOS) are naturally occurring oligosaccharides, mainly of plant origin.L. paracaseiadministered in combination with FOS significantly increased counts ofLactobacillusspp.,Bifidobacteriumspp., total anaerobes and total aerobes compared to the control group as well as theL. paracaseigroup. It also significantly decreasedClostridiumandEnterobacteriumcounts in the faeces of the weanling piglets compared with the control group. Dietary lipids influence the gastrointestinal microbiota and specifically the population of lactic acid bacteria. In gnotobiotic piglets the oral administration of an oil containing polyunsaturated fatty acids (PUFA) significantly increased the number ofL. paracaseiadhering to jejunal mucosa compared to the control group. Our results showed that maltodextrin KMS X-70 and PUFA can be used to enhance the effect of probiotic micro-organisms in the small intestine, and similarly FOS enhance the effect of probiotic micro-organisms in the large intestine.

Oil with higher a content of &omega;-3 polyunsaturated fatty acids (PUFA) was administered for 4 weeks to experimental germ-free piglets and from 21 days of age the piglets were inoculated perorally with probiotic micro-organisms <i>Lactobacillus casei</i> subsp. <i>casei</i>. Control piglets were administered saline solution in identical doses and starting from the fourth week were also supplemented with probiotics. At the age of 28 days, the number of <i>Lactobacillus casei</i> subsp. <i>casei</i> that had adhered to jejunal mucosa of experimental piglets was significantly higher (<i>P</i> < 0.05) compared to that in the control group. The differences in the number of lactobacilli, which colonised mucosa of the ileum and colon of experimental and control piglets, were insignificant. With the exception of the stomach, the pH level in the digestive tract of piglets was lower in the experimental piglets. Significantly higher levels of propionic (<i>P</i> < 0.05), acetoacetic and succinic (<i>P</i> < 0.01) acids were observed in germ-free experimental piglets in colon. The differences in the level of lactic and acetic acid were insignificant. PUFA-potentiated probiotics positively affected the adhesion of lactobacilli, pH and the level of organic acids in the digestive tract of germ-free piglets. Supplementation of oil containing &omega;-3 PUFA significantly increased the blood level of &alpha;-linolenic, eicosapentaenoic and docosahexaenoic acids in experimental piglets at the expense of arachidonic acid in comparison with the control.

In order to study the effect of dietary supplement of linseed oil on polyunsaturated fatty acids (PUFAs) in egg yolk of Gallus domestiaus, total 160 healthy Gallus domestiaus of 26-week old were randomly selected and divided into 4 groups, each of which included 40 chickens fed outdoors with an area of 63 m2 and free food and drinking water. The control group (CK) was fed the basic diet, and the experimental group was added 1, 3 and 5% of linseed oil in the fundamentals of diet (experimental group 1, 2 and 3, abbreviated as P1, P2, P3), respectively. The content of PUFA and the value of n-6 PUFA and n-3 PUFA in egg yolk were determined by gas chromatography with 24 eggs randomly selected in each group after 10th, 25th and 40th days of the commence of the experiment. We found that the levels of α-linolenic acid (C18:3n3, ALA) and docosahexaenoic acid (C22:6n3, DHA) in egg yolk were clearly higher than the CK when 3% linseed oil or 5% linseed oil were added in the diet during the three experiment periods, in which the contents of linoleic Acid (18:2n6c, LA) and arachidonic acid (C20:4n6, ARA) in egg yolk differ little between P1, P2 and P3 and the CK while the value of n-6 PUFA and n-3 PUFA in egg yolk of the P2 and P3 groups decreased significantly. The comprehensive comparisons suggested that the content of C18:3n3 and C22:6n3 in egg yolk could be clearly increased in the P2 while the value of n-6 PUFA and n-3 PUFA decreased. This study provides theoretical basis for the production of functional eggs enriched with C22:6n3 and C18:3n3.

The effect of supplementing fattening pigs with oils differing in MUFA (monounusaturated fatty acids) and PUFA (polyunsaturated fatty acids) level addition for fatteners diets on the cholesterol content of m. longissimus was investigated. In a feeding trial with 48 crossbred pigs [? ($ White Polish Large x S Polish Landrace) x <$ Pietrain] randomly assigned to four treatments groups of 12 animals each (6 gilts and 6 barrows), dietary supplements of 3% maize, sunflower or linseed oil in the experimental groups and of 3% lard in the control group were applied. Total cholesterol in the longissimus muscle of linseed oil supplemented pigs was found to decrease significantly (PO.01) compared to the lard-fed pigs (60.75 vs. 71.37 mg/100 g of fresh tissue). Similar tendencies for reduced cholesterol level in longissimus muscle of sunflower and maize oil supplemented pigs were also noted. The production of pork with reduced total cholesterol seems to be important in terms of consumer health and culinary value.

Fatty acid compositions were determined for total lipid (17.5% of the milk and > 95% triglycerides), 2-monoglyceride obtained by enzymatic hydrolysis of isolated triglyceride, and isolated phospholipid (~1% of total lipids). The total lipid fatty acids of the milk had a composition similar to fin whale depot fat but were enriched in hexadecanoic acid and polyunsaturated fatty acids at the expense of monoethylenic acids; correspondingly the iodine value of 136 (methyl esters) was higher than the normal range (105–120) of North Atlantic fin whale blubber oils. Over 80% of the fatty acids in the 2-position of the triglycerides were accounted for by relatively short chain fatty acids, especially hexadecanoic (54.6%), tetradecanoic (13.7%), and hexadecenoic (11.2%), so that the ester iodine value was only 48. The milk phospholipids had a fatty acid composition basically similar to that of liver phospholipids (methyl ester iodine value 120) with somewhat more polyunsaturated fatty acids and accordingly an iodine value of 144 for methyl esters.

Conjectural results have been reported on the capacity of inflammatory secreted phospholipase A2 (sPLA2) to hydrolyse mammalian membrane phospholipids. Development of an assay based on the release of non-esterified fatty acids by the enzyme acting on the organized phospholipid mixture constituting the membrane matrix has led to the identification of two prominent effectors, sphingomyelin (SPH) and annexin. Recombinant human type II sPLA2 hydrolyses red-cell membrane phospholipids with a marked preference for the inner leaflet. This preference is apparently related to the high content of SPH in the outer leaflet, which inhibits sPLA2. This inhibition by SPH is specific for sPLA2. Cholesterol counteracts the inhibition of sPLA2 by SPH, suggesting that the SPH-to-cholesterol ratio accounts in vivo for the variable susceptibility of cell membranes to sPLA2. Different effects were observed of the presence of the non-hydrolysable D-α-dipalmitoyl phosphatidylcholine (D-DPPC), which renders the membranes rigid but does not inhibit sPLA2. Annexin VI was shown, along with other annexins, to inhibit sPLA2 activity by sequestering the phospholipid substrate. The present study has provided the first evidence that annexin VI, in concentrations that inhibit hydrolysis of purified phospholipid substrates, stimulated the hydrolysis of membrane phospholipids by sPLA2. The activation requires the presence of membrane proteins. The effect is specific for type II sPLA2 and is not reproducible with type I PLA2. The activation by annexin VI of sPLA2 acting on red cell membranes results in the preferential release of polyunsaturated fatty acids. It suggests that type II sPLA2, in conjunction with annexin VI, might be involved in the final step of endocytosis and/or exocytosis providing the free polyunsaturated fatty acids acting synergistically to cause membrane fusion.

Abstract The aim of the study was to determine the impact the commercial supplement S.presso (INVE Aquaculture, Belgium), a source of polyunsaturated fatty acids to enrich the proximate composition of brine shrimp (Artemia sp.), had on their growth and mortality. Four different enrichment protocols were investigated: the supplement was given in one or two doses at various time intervals. The results indicate that while S.presso increased nauplius mortality slightly, administering the appropriate dose reduced losses to a very low level (from 12.5% with a single dose to 8.6% with the recommended dose divided into to equal parts). Additionally, it was confirmed that the supplement S.presso increased brine shrimp growth slightly in comparison to that of the control group, but the differences were statistically insignificant. The results permit concluding that S.presso is suitable for use as a source of polyunsaturated fatty acids for brine shrimp enrichment with the intent of using them as fish food.

The beneficial effect of omega-3 polyunsaturated fatty acids (PUFA) supplementation on the cardiovascular (CV) system is well supported in CV patients; however, the effect of the consumption of omega-3 PUFA-enriched functional food in healthy individuals is still not fully elucidated. This study aimed to determine the effect of the consumption of omega-3 PUFA-enriched hen eggs on the microvascular reactivity (primary outcome), blood pressure (BP), and serum lipid profile in young healthy individuals. The control group (N = 16) ate 3 ordinary hen eggs (277 mg of omega-3 PUFAs/day), and the OMEGA-3 group (N = 20) ate 3 omega-3 PUFA-enriched eggs containing 259 mg of omega-3 PUFAs/egg daily (α-linolenic acid (ALA), 167 mg/egg; eicosapentaenoic acid (EPA), 7 mg/egg; docosahexaenoic acid (DHA), 84 mg/egg) for 3 weeks (777 mg of omega-3 PUFA/day). Postocclusive reactive hyperemia (PORH) in skin microcirculation assessed by laser Doppler flowmetry, serum lipid profile, fasting blood glucose, high-sensitivity C-reactive protein (hsCRP), and arterial BP were measured in all subjects before and after the protocol. PORH was significantly enhanced, and triglycerides, hsCRP, and BP were significantly decreased in the OMEGA-3 group compared with baseline measurements, whereas there was no significant difference in the control group after the protocol when compared with baseline. To the best of our knowledge, this is the first study to demonstrate that consumption of a mixture of omega-3 PUFA (ALA + EPA + DHA), provided via enriched hen eggs, elicits changes in the microvascular reactivity, BP, and triglyceride level in healthy subjects that are associated with CV benefits, thus suggesting that daily consumption of omega-3 PUFA-enriched eggs in healthy individuals may potentially contribute to CV risk factor attenuation and disease prevention.

The study was aimed at testing the hypothesis that perioperative infusion of omega-3 polyunsaturated fatty acids would reduce the incidence of postoperative atrial fibrillation in CAD patients operated under CPB. The authors carried out a prospective, randomised, double-blind, placebo-controlled study. 39 CAD patients who had undergone surgery under cardiopulmonary bypass were randomized into 2 groups. 18 patients were infused with omega-3 polyunsaturated fatty acids (Omegaven, Fresenius Kabi, Germany) starting with 200 mg/kg/day before anaesthesia induction for 24 hours followed by 100 mg/kg/day from second to seventh day postoperatively. 21 patients received an equivalent dose of placebo (Intralipid, Fresenius Kabi, Germany). The primary endpoint was freedom from atrial fibrillation at 2-year follow-up. A Reveal cardiac monitor was implanted subcutaneously in all patients. Data from cardiac monitor was collected on the 10th day and at 3, 6, 12 and 24 months postoperatively. Postoperative atrial fibrillation developed in 4 (19%) patients in the control group and in 5 (27.8%) patients in the study group at 10-day follow-up (p = 0.88). At 2-year follow-up, 5 (27.8%) patients in the control group and 6 (35.3%) patients in the study group had atrial fibrillation (p = 0.9). The results of our research do not confirm the efficiency of perioperative infusion of omega-3 polyun-saturated fatty acids to prevent the occurrence of atrial fibrillation.

Objectives. It  was to assess the degree of neurological deficit in rats with cerebral ischemia and administration of omega-3 polyunsaturated fatty acids. Methods. The experiments were carried out on 42 male outbred white rats weighing 260 ± 20 g. Modeling of cerebral ischemia was carried out under conditions of intravenous thiopental anesthesia (40-50 mg / kg). The studies used models of subtotal, partial and stepwise subtotal cerebral ischemia. The table shows the experimental groups and the number of animals in them. Subtotal cerebral ischemia (SCI) was modeled by simultaneous ligation of both common carotid arteries (CCA). Partial cerebral ischemia (PCI) was modeled by ligating one CCA on the right. Stepwise subtotal CI (SSCI) was performed by sequential ligation of both CCA with an interval of 1 day (subgroup 1), 3 days (subgroup 2), or 7 days (subgroup 3). To study the effects of omega-3 polyunsaturated fatty acids (ω-3 PUFA), animals with CI were injected intragastrically with the drug "Omegamed" (SCI+ω-3 PUFA) at a dose of 5 g / kg body weight for a week. The control group consisted of sham-operated rats of the same sex and weight. Neurological deficits were assessed in the "muscle strength", "swimming test" and "open field" tests after 5-6 hours of the ischemic period. Results. With a stepwise bilateral ligation of both common carotid arteries with an interval of 1 day, neurological disorders were most pronounced, which indicates an aggravation of neurological deficit with a reduction in the time between CCA dressings. In rats with SCI, the changes were more pronounced than with PCI, but less than with SCI. The least pronounced changes were noted in the 3rd subgroup (the interval between CCA dressings was 7 days). Studies have shown the dependence of the severity of brain damage in SSCI on the interval between the cessation of blood flow in both CCA. At a 7-day interval between CCA dressings, compensatory mechanisms were activated, which prevented the development of morphological changes and neurological deficits. When CCA was ligated with an interval of 1 day, the degree of neurological deficit was maximal, which indicates insufficient implementation of compensatory mechanisms. Compared with the control group, the rats of the "SCI+ω3-PUFA" group retained neurological deficit, the muscle strength indicator was 86% less (p<0.05), the swimming duration - by 63% (p<0.05), the number of crossed squares - by 55% (p<0.05), the number of washes - by 62% (p<0.05), the number of racks - by 62.5% (p<0.05) and the number of bowel movements - by 60% (p<0.05). However, in comparison with the SCI group, the neurological deficit was less pronounced. There was an increase in muscle strength by 67% (p<0.05), swimming duration by 37.5% (p<0.05) and the number of squares crossed in the open field test by 31% (p<0.05), which indicates the presence of a corrective action in the ω3-PUFA preparation. Conclusion. The introduction of the preparation of ω-3 polyunsaturated fatty acids has a corrective effect in conditions of subtotal cerebral ischemia, contributing to a lesser severity of manifestations of neurological deficit (an increase in muscle strength, duration of swimming and the number of squares crossed in the open field test).   Key words: cerebral ischemia, rats, neurological deficiency, omega-3 polyunsaturated fatty acids.
