Background: CORN OIL plays an important role in supplying essential fatty acids and vitamin E, however, its impact on cardiovascular and immune system was not negligible. This product is mainly composed of unsaturated fatty acids and small amounts of saturated fatty acids. This study was conducted to determine the effects of CORN OIL on rats body composition, physical growth, and blood fat concentration.Materials and methods: 8 rats were divided in two groups of case and control and studied for 9 weeks. Rats were killed by means of ether and 5cc blood was taken for determined laboratory tests. Their cadavers were used for protein and fat analysis. For the first 4 weeks both groups have received the same regimen, but after that the case group (receiving CORN OIL) was given less food. Results: Total food intake was 1300±128 and 1059±69 gr in the control and case group, respectively. The control group has received fewer calories in comparison with the case group. No significant difference was found between the groups concerning the cholesterol, LDL, and triglyceride level, however, HDL level was reported higher in the case group. Both groups had similar amount of protein, but the case group has shown higher amount of fat and lesser amount of carbohydrate.Conclusion: Regarding the higher amount of HDL in the CORN OIL group (case), further studies are highly recommended.

Purpose: The purpose of this study was to evaluated the effect of CORN OIL on mouse sperm count, motility, viability, quality of chromosome, testicular spermatid number per gram testis (TSN), anddaily sperm production (DSP). Materials and Methods: The protocol for CORN OIL adminstration was that male NMRI mice (the age groupe of 4weeks) received 100 and 150 ml CORN OIL orally for 14 days. The control group did not receive CORN OIL.All animals were weighed on the first and terminal day of experiment and then killed by cervical dislocation. The right and left testis weight without fat were recorded for each animal. sperm analysis was evaluated the end of this time. Epididymal spermatozoa from adult mice were collected in T6 medium supplemented with 4mg/kg BSA and the preserved sample at incubator 37oc for 1 hour. All the samples were assessed according to world healt organization criteria.Abnormal morphlogy was assessed using papanicula staining. Quality of choromosome sperm also was assessed using anilin-blue staining. After detached capsule right testis, the paranchyma was homogenized at low speed for 4 minutes in 2 ml of 0.4% Nacl solution. Homogenization-resistant spermatid heads were counted by aimproved neubar haemocytometer. Number of spermatid were expressed at TSN. DSP was calculated by dividing the total number of spermatid per gram testis by 4.84 (The duration of step 14-16 spermatids in the mouse seminiferous epithelial cycle.) One-way ANOVA and Kruscal-Walis H were utilized on parameters. Results: The results showed that 100 and 150 ml CORN OIL daily adminstration decrease count, viability, motility, abnormal morphlogy and quality of chromosome epididymal sperm, TSN, DSP, and body weight mouse compared the control group, but there wasnot seen significant difference (p>0.05). It is no effect on testis weight.Conclusion: The result of this study demonstrated that CORN OIL admistration is low negative effect on parameters sperm mouse.It is good solvent for reproductive system research studies.

In this study, the effects of CORN OIL on spatial learning have been investigated. Male rats were trained for a spatial learning task using T-Maze. The rats were divided into four groups and 9 rat were considered for each group. The first group, control group was fed with an ordinary diet and the other groups were fed with a diet containing CORN OIL (10%) for two, three and four weeks. All rats were trained for 9 days based on standard method. Results showed an increase of spatial learning in rats fed 10% CORN OIL in their diet for three and four, but nor for two, weeks was significant (P<0.05). It seems that polyunsaturated fatty acids like linolenic and linoleic acids have a modulatoty role in spatial learning in rats.

One of the procedures for the stabilizing of frying OIL, in order to preserve the synthetic antioxidants, is adding OILs containing antioxidant and high oxidative stability compounds. The objective of this research was the quality evaluation of three frying OILs mixture (Sunflower, Ladan and Iran) due to the addition of purslane and CORN seed OILs and frying over 12 h at 170± 2  C for this reason, the mixed frying OIL, containing CORN and purslane seed OIL in the proportion of (70: 15: 15 w/w) called mixture 1, mixed frying OIL containing CORN and purslane seed OIL in the proportion of (75: 15: 10 w/w) called mixture 2, CORN seed OIL, purslane seed OIL and mixture of three frying OILs in terms of qualitative indexes (peroxide, p-anisidine, totox, total polar compounds, oxidative stability and conjugate-DNs), were evaluated. At first the antioxidant activity rate of purslane seed OIL was assessed and the value of 52. 9± 0. 19 percent was measured. The comparison of two types of frying OIL mixtures indicated that the values of peroxide, p-anisidine, totox and conjugate-DNs, indicators of mixture 1 and 2 were (25. 83 meq/kg, 80. 63, 132. 29 and 15. 01 μ mol/g) and (28. 13 meq/kg, 85. 73, 141. 99 and 17. 17 μ mol/g) respectively which had significant difference with frying and other OILs (P<0. 05). The higher ratio of purslane OIL in the frying OIL, mixture 1, increased its oxidative stability in contrast to OIL mixture 2 and purslane preserved it against early degradation at high temperature.

Background: The potential role of omega- 3 (ω-3)and omega-6 (ω-6) fatty acids on blood biochemical factors are in interest and controversy Some experiences showed that omega-3 (ω-3)and omega-6(ω-6) fatty acids have a potential effect on triglyceride, LDL-cholesterol, HDL-cholesterol and total cholesterol levels in diabetes mellitus.Methods: Male, rats were divided into four groups. (one normal group and three diabetic groups). Induction of diabetes was done by streptozotocin [50mg/kg, s.c., (STZ)]. In diabetic  groups, one group was Control, received STZ alone, and the other diabetic groups were fed with fish OIL or CORN OIL for 8 weeks after 4 weeks of induction of diabetes. Plasma glucose, total cholesterol, triglyceride, LDL- cholesterol and, HDL cholesterol were measured at 4 and 8 weeks after intervention.Results: Fish OIL and CORN OIL diets had an inhibitory effect on increased plasma glucose in diabetic rat by 46:8% and 40.7% respectively. Diabetic rats in the control group demonstrated, increased plasma, total cholesterol, triglyceride and LDL-cholesterol levels, but plasma total cholesterol,  triglyceride and -LDL-cholesterol levels, were significantly decreased and HDL-cholesterol level was increased by both diets in interventional groups. Conclusion: CORN OIL and fish OIL supplementation have a role on plasma glucose and lipid profile in diabetic rats. To understand the functional mechanisms of these diets, further studies remain to be accomplished.

This study was designed to examine bioactive compounds of the thyme-enriched CORN OIL and to determine the antioxidant activity of its methanolic extract. Volatile compounds composition was investigated by Gas Chromatography-Mass Spectrometry (GC-MS), whereas phenolic compounds analysis was performed by Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC). Antioxidant activities of the flavoured OIL methanolic extract were evaluated using DPPH radical scavenging,  -carotene-linoleic acid bleaching, reducing power and total antioxidant assays. Flavoured OIL major volatiles were p -cymene (26.47%), a-thujene (24.06%) and -terpinene (14.30%). Its methanolic extract had higher Total Phenol Contents (TPCs) (53.99 mg 100 g-1) than that of the crude OIL (23.63 mg 100 g-1). Thymol was the main phenolic compound in the flavoured OIL (55.84%). Flavoured OIL methanolic extract showed higher total antioxidant activity (185.22 mg Gallic Acid Equivalent (GAE) 100 g-1) than that of the crude one (100.66 mg GAE 100 g-1). In b-carotene-linoleic acid bleaching and DPPH radical scavenging assays, flavoured OIL methanolic extract showed higher activities than that of the crude OIL based onIC50 values. Flavoured and crude OILs were characterized by a close CE50values (1.81 and 1.85 mg mL-1, respectively). Antioxidant activities of the thyme-enriched OIL were mainly due to the presence of phenolic compounds such as thymol and hydrocarbons such as -terpinene and p - cymene. The thyme-enriched OIL could be considered as a new and natural source of antioxidant.

The present study investigates the t C and 1 atm. These two catalysts have been prepared via a conventional co-precipitation process. As for MgO, the corresponding mixed metal nitrate solution has been mixed and heated at the presence of urea. ZnO has also been synthesized by co-precipitation of metal acetate at the presence of oxalic acid and ethanol. The catalysts then have been characterized by means of X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). XRD results indicate high purity for both catalysts. Also, catalytic activity has been evaluated in methanol reflux temperature through CORN OIL transesterification, with the impacts of reaction variables, like catalyst amount, methanol/OIL molar ratio, and reaction time on biodiesel yield, investigated by means of HNMR spectrum. Under appropriate transesterification conditions at 65 ° C (catalyst amount= 5%, methanol/ OIL ratio= 20, and reaction time= 10 hr), an ME content of 62. 61% can be achieved, using MgO catalyst. Similarly, the experiments have been repeated to achieve the best yield, using ZnO catalyst, with the highest rate, equal to 53. 1%, obtained in 9% of catalyst and methanol/OIL ratio of 30 over 10 hr. Furthermore, reusability of ZnO and MgO has been evaluated in transesterification reaction.
