In this study, it was aimed to investigate the protective effect of black seed oil against testicular tissue damage in diabetic rats. A total of 18 male rats were divided into 3 groups, including 6 rats in each group.Groups; control (n=6), diabetes (n=6), diabetes + black seed oil (n=6). A single dose of 45 mg / kg streptozocine (STZ) was injected intraperitoneally to induce diabetes. Diabetes + Black seed oil group: For 56 days, 2.5 ml / kg of black seed oil was administered orally to rats.The rats were sacriced at the end of 56 days. Testicular tissues were taken for routine parafn tissue processing for histopathological examination. Parafn sections were stained with Hematoxylin-Eosin and PAS and examined under a light microscope. Atrophy and degeneration were observed in the seminiferous tubules of diabetic group. Histology of black seed oil group sections were similar to that of control group. A signicant difference was found between the black seed oil group and the diabetes group in terms of blood glucose values. As a result, we think that Black Seed Oil ameliorates to the tissue damage caused by diabetes and the decrease in blood sugar value.

The current study focused on investigating the renoprotective effects of grape seed oil (GSO) against hexavalent chromium (Cr (VI))-induced nephrotoxicity. A total of 40 male rats were randomly divided into four groups: group I served as the control group, group II received 1000 mg/L potassium dichromate (353.5 mg/L Cr(VI)) in drinking water for 12 weeks, group III received 3.7 g/kg body weight/day GSO orally for 12 weeks, and group IV received GSO together with potassium dichromate for 12 weeks. Cr(VI) significantly increased serum levels of urea, creatinine, potassium and glucose. In addition, Cr(VI) increased MDA levels and induced renal tissue damage and DNA damage. On the other hand, Cr(VI) decreased serum levels of sodium and antioxidant defence system [reduced glutathione (GSH) and catalase (CAT)]. However, treatment with GSO prevented elevation levels of serum urea, creatinine, potassium and glucose. In addition, GSO enhanced sodium level, renal tissue antioxidant defense system due to its curative effect ameliorated particularly oxidative stress, renal tissue and DNA damage. In conclusion, these results demonstrate that GSO is a promising nephroprotective agent against Cr(VI)-induced nephrotoxicity.Key words: grape seed oil; hexavalent chromium; nephrotoxicity; DNA damage BLAŽILNI UČINKI OLJA GROZDNIH PEŠK PRI TOKSIČNI OBREMENITVI LEDVIC TER VPLIV NA OKSIDATIVNI STRES PODGAN, POVZROČEN S KROMOM Povzetek: Študija je bila osredotočena na proučevanje zaščitnih učinkov olja grozdnih pešk (GSO) pri toksični obremenitvi ledvic, povzročeni s heksavalentnim kromom (Cr (VI)). Štirideset samcev podgan je bilo naključno razdeljenih v štiri skupine: skupina I - kontrolna skupina, skupina II, ki je v pitni vodi 12 tednov prejemala 1000 mg/L kalijevega dikromata (353,5 mg/L Cr (VI)), skupina III, ki je peroralno 12 tednov prejemala 3,7 g/kg telesne mase/dan GSO ter skupina IV, ki je 12 tednov prejemala GSO skupaj s kalijevim dikromatom. Cr(VI) je znatno zvišal serumske ravni sečnine, kreatinina, kalija in glukoze v serumu. Poleg tega je Cr(VI) zvišal raven MDA in povzročil poškodbe ledvičnega tkiva in poškodbe DNK. Po drugi strani je Cr(VI) znižal serumsko raven natrija in antioksidativnega obrambnega sistema, zmanjšal raven glutationske peroksidaze in katalaze. Dodajanje GSO poskusnim živalim je preprečilo zvišanje ravni sečnine v serumu, kreatinina, kalija, natrija in glukoze. Poleg tega je GSO izboljšal obrambni sistem antioksidantov ledvičnega tkiva. Zaradi svojega zdravilnega učinka je izboljšal zlasti oksidativni stres, poškodbe ledvičnega tkiva in DNK. Rezultati kažejo, da je GSO obetavno zaščitno sredstvo za ledvica pri toksični obremenitvi, povzročeni s Cr(VI).Ključne besede: olje grozdnih pešk; heksavalentni krom; nefrotoksičnost; poškodba DNK

Seed oil from flax (Linum usitatissimum) is enriched in α-linolenic acid (ALA; 18:3Δ9cis,12cis,15cis), but the biochemical processes underlying the enrichment of flax seed oil with this polyunsaturated fatty acid are not fully elucidated. Here, a potential process involving the catalytic actions of long-chain acyl-CoA synthetase (LACS) and diacylglycerol acyltransferase (DGAT) is proposed for ALA enrichment in triacylglycerol (TAG). LACS catalyzes the ATP-dependent activation of free fatty acid to form acyl-CoA, which in turn may serve as an acyl-donor in the DGAT-catalyzed reaction leading to TAG. To test this hypothesis, flax LACS and DGAT cDNAs were functionally expressed in Saccharomyces cerevisiae strains to probe their possible involvement in the enrichment of TAG with ALA. Among the identified flax LACSs, LuLACS8A exhibited significantly enhanced specificity for ALA over oleic acid (18:1Δ9cis) or linoleic acid (18:2Δ9cis,12cis). Enhanced α-linolenoyl-CoA specificity was also observed in the enzymatic assay of flax DGAT2 (LuDGAT2-3), which displayed ∼20 times increased preference toward α-linolenoyl-CoA over oleoyl-CoA. Moreover, when LuLACS8A and LuDGAT2-3 were co-expressed in yeast, both in vitro and in vivo experiments indicated that the ALA-containing TAG enrichment process was operative between LuLACS8A- and LuDGAT2-3-catalyzed reactions. Overall, the results support the hypothesis that the cooperation between the reactions catalyzed by LACS8 and DGAT2 may represent a route to enrich ALA production in the flax seed oil.

The present study analyses the effect of flax-seed oil rich in n-3 polyunsaturated fatty acids (PUFAs), the probiotic strain Lactobacillus plantarum — Biocenol™ LP96 and their combination on the expression level of selected Toll-like receptor (TLR) genes (TLR2, TLR4, TLR5, TLR9) and their downstream molecules (myeloid differentiation factor 88, MyD88; nuclear factor-κB, NF-κB) in the jejunum of gnotobiotic pigs challenged with enterotoxigenic Escherichia coli (ETEC). The results show that both immunomodulators are able to modulate the RNA level of at least one of the target molecules and thus regulate pathogeninduced inflammation. We confirmed that not only probiotic lactobacilli or flaxseed oil alone but also their synergistic action has great potential in the prevention and treatment of porcine colibacillosis. The results give an insight into one of the possible mechanisms by which natural agents, such as probiotic lactobacilli and flax-seed oil, exert their immunoregulatory properties during pathogen-induced inflammation.

In 26 field experiments over a 4-yr period, weed interference significantly reduced the oil content of flax seed (Linum usitatissimum L. ’Linott’) in 21 of the experiments and the iodine value of flax seed oil in 19 of the experiments, regardless of dominant weed species. Seed density and seed weight were not seriously affected by weed interference. Flax seed yields were reduced by weed interference in 25 of the experiments.Key words: Flax, weed competition, linseed oil

Purpose: Alzheimer’s disease (AD) is a chronic neurodegenerative disorder, with an increasing prevalence rate, mostly related to cholinergic system. According to the difficulties and complications in management of AD, this study was carried out to evaluate the efficacy of grape seed oil (GSO) on scopolamine (Scop) induced Alzheimer’s in male rats. Methods: 64 healthy male Wistar rats received different treatments such as: normal saline (NS), donepezil (Don), Scop and GSO, according to the previously designed protocol. Morris (MWM) was applied for spatial memory tests. Right after the behavioral tests, the brains were removed and the hippocampus was separated for evaluation of acetylcholine levels as well as cell death and neuro inflammation. Results: The results of the test day indicated that the mean Q2 time was increased in both GSO test groups (P<0.05) and Don treated group (P<0.001).The spectrophotometric findings affirm that both GSO co-treatment and post-treatment were effective in augmenting brain acetylcholine levels (P<0.01 and P<0.05 respectively). The microscopic findings of Hamp;E dyed tissues confirmed the above mentioned results for different treatments except for GSO post treatment, in which the viability of cells were very low. Conclusion: The results implied that supplementation of rats with GSO caused a significant augmentation in spatial memory performance as well as acetylcholine levels and cell viability in the presence of Scop. This effect was comparable to that of Don especially when GSO was used as co-treatment.
