Abstract

Objective: The role of vitamin D has soared to a pinnacle in recent years with functions affecting 229 human genes linked to cardiovascular, autoimmune, humoral, pulmonary and neurological diseases. Relationship between obesity and vitamin D has not as yet been fully established. The objective of the study was to determine the possible relationship between Vitamin D receptor (VDR) gene polymorphisms and the risk of obesity. Methods: Total 100 subjects (50 obese and 50 normal) were selected. Oral rinse samples were collected (between 18-45 years of age) after an informed consent. DNA was extracted and PCR was performed using VDR-Fok1 primers. A 256bp amplified products was visualized by Gel Doc Hero Lab software (Germany). Results: The results of VDR-Fok1 gene polymorphism showed that out of 50 obese subjects 40%were normal (FF=20), 54%were Heterozygous (Ff = 27) and 6% were mutated (ff= 3). Out of 50 nonobese subjects 84% were normal (FF= 42), 16% were Heterozygous (Ff= 8) and none were mutated (ff= 0%). The statistical analysis results between the ff genotype and obesity were not significant. The ff genotype of VDR may be associated with obesity. More studies with larger sample size are required to find a stronger correlation.

Abstract

Objective: In recent years, amino acids are used in veterinary medicine for many purposes. They injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. There is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. The objective of this study was to investigate the pathological alterations of triaminohexanoic acid for chicken embryo. Methods: Fertile chicken eggs were divided into two equal treatment groups as follows: phosphate buffered saline-injected group and triaminohexanoic-injected group whose individuals were injected with a triaminohexanoic acid solution at a dosage of 10 mg per Kg eggweight. Embryos were re-incubated post-treatment and allowed to develop until day 18 after which; they were examined for macroscopic lesions. Results: Results showed that embryos were normal in all treatment groups. Macroscopically, no lesions were also diagnosed in tissues. Based on macroscopic findings, it is concluded that triaminohexanoic acid at above-mentioned concentration is not toxic for the chicken embryo. Therefore, triaminohexanoic acid egg-injection can be used for increasing chick performance at hatch without any adverse effect.

Abstract

Objective: This study was to evaluate the effect of Vitamin C on the histology and histochemistry of the prefrontal cortex of ethanol-induced rats. Methods: Male SpragueDawley rats were used for the study. Ethical approval was obtained from the University’s ethical committee. The rats were randomly divided into 6 groups of 10 rats each. Rats in group A= free access to normal saline. Rats in group B= treated with 4.25 ml ethanol. Rats in group C= treated with 100 mg/kg Vit. C. Rats in group D= pre-treated with 100 mg/kg Vit. C followed by 4.25 ml ethanol. Rats in group E=co-treated with 100 mg/kg of Vit. C and 4.25ml ethanol. Rats in group F=post-treated with 4.25ml ethanol followed by 100 mg/kg Vit.C. 24hrs after the last administration, the rats were sacrificed by cervical dislocation: the fraction of the brain for tissue histochemistry was fixed in formol calcium and later processed for Heamotoxylin and Eosin with Cresyl fast violent staining techniques and the other fraction meant for enzyme and/or marker histochemistry was processed accordingly for some neurochemical indices for oxidative stress. Results: The markers of oxidative stress were statistically increased in the rats in group D, E and F compared with the rats in group B. There is a significant reduction of TBARS when compared with ethanol induced group (group B). The histological profile of the prefrontal cortex of rats in group A and C were preserved while that of the rats in group B displayed distorted cytoarchitecture profile with a marked increase in apoptotic bodies, lateral deviation of neurons and a marked increase in the activities of oxidative markers.

Abstract

Objective: It has been shown that deferasirox can reduce blood and tissues lead content in animal models. In this study the effect of deferasirox alone or combined with glycine as an antioxidant was evaluated in chronic cadmium toxicosis in rat. Methods: Male wistar albino rats were exposed to 200 ppm cadmium in the drinking water for 3 weeks and treated thereafter with deferasirox (140 mg/kg), glycine (1000 mg/kg) and deferasirox (140 mg/kg) + glycine (1000 mg/kg) by oral gavages, twice daily for 7 days. The effect of these treatments on blood, liver, kidney, bone and testis cadmium values and parameters indicative of oxidative stress (superoxide dismutase, catalase, glutathione peroxidase and total antioxidant capacity in blood) were investigated. Results: Deferasirox was found to be effective in reducing cadmium level in blood, liver and kidney and glycine reduced cadmium levels in bone. Individual administration of deferasirox or glycine mitigated the effects of cadmium on some indicative parameters of oxidative stress in blood. But the best results were obtained following co-administration of both drugs.

Abstract

Objective: Oxidative stress that damages proteins result in aging and age related diseases. The aim of this study is to determine the effect of tocotrienol rich fraction (TRF) on the expression of proteins in oxidative stress-induced caenohabditis elegans (C.elegans) which has homologous genes to humans. Methods: The worms were treated with TRF prior to, after and continuously in separate groups upon induction of oxidative stress with hydrogen peroxide. The expression of proteins were analyzed with 2D-gel electrophoresis and identified with mass spectrophotometry. Results showed that induction of oxidative stress and TRF treatment separately modulated the expression of 11 proteins. Pre-treatment of TRF altered the expression of 5 proteins while posttreatment and a continuous treatment of TRF in oxidative stress-induced worms affected the expression of 9 and 10 proteins respectively. Results: From these differentially expressed proteins, a total of 12 were successfully identified. TRF was found to increase the expression of glutathione-S transferase but decreased the expression of mRNA cap guanine-N7 methyltransferase, inorganic pyro-phosphatase, enoyle-CoA hydratase, vitellogenin 6 precursor, cathepsin B-like cysteine proteinase 4 precursor, triosephosphatase isomerase, tubulin-specific chaperon B and putative D-amino acid oxidase. In conclusion, TRF modulated the expression of proteins involved in energy metabolism, oxidative stress, proteolysis and biosynthesis of mRNA in C.elegans.

Abstract

Objective: A secondary ectopic pregnancy is defined as continuing development of a fetus in the abdominal cavity after rupture of the uterine wall, which may be associated with a history of trauma. Methods: A cat was referred to the veterinary teaching hospital of the University of Tehran with history of anorexia and vaginal bleeding. In clinical examination some masses werepalpated in abdominal cavity so the patient wasreferred to radiology and sonography for definite diagnoses. In ultrasonography examination three dead fetuses were detectedoutside the uterus. In US it so appeared that gestational sacs did not cover the fetuses and there was a rupture in cranial part of right uterine horn that made the case highly suspected to ectopic pregnancy caused by trauma. Results: Therefore the cat was prepared for aseptic surgery and anesthetized with isofulorane. After incision of the lineaalba three fetuses were seen outside the uterus that wereattached to abdominal wall (left and right wall) and mesentery. There was no sign ofgestational sac to cover the fetuses. The three fetuses were bluntly dissected from the attachments and all conspicuous vessels were ligated and the fetuses were removed. Ovariohysterectomy was also performed to prevent recurrence. Recovery was uneventful.

Abstract

Objective: A magnesium deficiency is known to be involved in many abnormalities in the post-menopausal women. Previous studies proposed that magnesium (Mg) might prevent atherosclerosis. In this study the efficacy of serum magnesium level and its relation with carotid intima media thickness (CIMT) in post-menopausal women was evaluated. Methods: Eighty Iranian Postmenopausal women were included in final analysis.The serum Mg level was evaluated. The CIMT was assessed bilaterally using an ultrasonography in the 4 points at 2 cm proximal to the bulb, the 4 points at 2 cm distal to the bulb and 2 points at the carotid bulb and averaged to obtain the mean IMT.A thorough history of age and duration of menopause was taken from each patients. Data was analysed by SPSS software. Results: In all the patients of case group, a significant increase in intima media thickness of common carotid artery was observed(p≤0.001).Increased intima media thickness was associated with reduced serum level of Mg. Conclusion: This study shows that lower serum level of Mg are associated with higher CIMT in postmenopausal women. Nutritional status of the customary high intake of the marginal Mg might well be contributory to prevent the adverse effects of cardiovascular diseases.Therefore ,patients with lower serum level of Mg may have a high risk of increased CIMT.

Abstract

Objective: For investigation of intercropping of maize and faba bean, an experiment was conducted in Research Station of Agriculture Faculty of Tabriz University during growing season of 2013. Methods: Experimental design was randomized complete block design with three replications and seven treatment. Treatments included one row intercropping (1:1), 4 strip intercropping pattern with ratios of (1:2), (1: 3), (2: 1) and (2: 2) maize and faba bean and 2 treatments of faba bean and maize sole culture. Results: Based on results, grain yield and biological yield of two species in sole culture was significantly different from other species and reached their highest level. Evaluation of different patterns of intercropping using Land Equivalent Ratio (LER) showed that strip intercropping with ratio 2:2 dedicated highest ratio of LER to itself. Regarding to maize as a major yield in all cropping patterns, economic value or Relative Value Total (RVT) was lower than one, but regarding to economic production of faba bean, RVT of all intercropping was more than one, and among them strip intercropping 2:1 had highest RVT(9.65). Relative Crowding Coefficient (RCC) showed that in treatments which crowding one of two species is more than other, that species is superior competitively.

Abstract

Objective: In recent years, antiviral drugs have been used widely in the glob to prevent and treat viral diseases. They injected into eggs to eliminate pathogens and prevent of egg transmission of disease, but the adverse effects of drugs have always been a major concern. There is little information available about the safety of antiviral drugs in the embryonated eggs of birds. The objective of this study was to evaluation of the effect of acyclovir on the viability of chicken embryo during the first trimester of the incubation period. Methods: Fertile chicken eggs were divided into two equal treatment groups. The phosphate buffered saline injected group and acyclovir-injected group whose individuals were injected with acyclovir solution at a dosage of 80 mg per Kg egg-weight. Embryos monitored daily during incubation until day 10 after which; they were examined for viability. Results: Results showed that all of the embryos were dead in the acyclovir-injected group. Based on findings, it is concluded that acyclovir at abovementioned concentration has a severe lethal effect on the chicken embryo. So, acyclovir egg-injection cannot be used to eliminate pathogens and prevention of egg transmission of the disease.

Abstract

Objective: Salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. This study was undertaken to investigate salt tolerance in Salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. Methods: This study had two parts of greenhouse and natural habitats. The treatment solutions for salinity tests were different concentrations of NaCl and Na2SO4 (0, 100, 200, 300, 400, and 500 mM) with three replicates and growth parameters and proline and soluble sugar were determined in vegetative growth stage in greenhouse. Soil (two depths of 0-10 cm and 10-45 cm) and plant (root and shoot) samples have been harvested from three 200 meters transects in three provinces of Esfahan, Semnan and Markazi. Plant proline and soluble sugar and soil texture and EC were measured in laboratory. Collected data were analyzed using a factorial experiment and means were compared by DMRT method by SPSS software. Results: Results indicated that proline and soluble sugar were significantly affected by salinity levels and increased with salinity increase. The rate of growth parameters increased with an increase in salinity up to 300 mM while salinity levels more than 300 mM NaCl caused all growth characteristics decline. Data obtained from the laboratory experiment confirmed the findings noted during the field study. It has to be mentioned that nature is unpredictable and observing unexpected trends under specific conditions is not impossible.

Abstract

Objective: Citrus (Citrus reticulata) is one of the most important horticultural plant in Iran and weed management throuth ecological methods such as cover crop is a proper option in orchard management practices. Methods: The experiment was designed as a split plot on the base of complete randomized block design with four replications in Mazandaran Province, Sari, Voushka county from 2010 to 2012. The main plots were methods of cover crop management (desiccated with glyphosate at 0.85 kg ai ha-1, mowed and incorporated with soil with rotivator that were done at the flowering stage), and the subplots were cover crop species [sainfoin (Onobrychis viciifolia), winter barely (Hordeum vulgare), triticale (×Triticosecale), sainfoin + barely and sainfoin + triticale] and one control treatment which was without cover crop. Results: An important reduction of seedling emergence and total weed dry weight were observed in the plots with cover crop dessicated compared with the plots mowed or incorporated with soil. The optimum cover crop species for weed control was sainfoin + barely mixes because it had the highest biomass and lowered the amount of light reaching the soil surface and reduced soil temperature fluctuations, resulting in a reduction in weed seedling emergence. In addition weed suppression by it has been attributed in part to allelopathy. In both years there were no differences among treatments in tree yield but to maximize and sustain the output of an orchard, weeds in the tree row have to be controlled efficiently.

Abstract

Objective: Teucrium polium L. (family Lamiaceae) is a wild-growing flowering plant, found abundantly in South-Western Asia, Europe and North Africa. Traditionally, T. polium has been used for different pathological conditions such as gastrointestinal disorders, inflammations, diabetes and rheumatism. The purpose of this study was to evaluate the antimicrobial effect of ethanol extract of Teucrium polium against Salmonella typhimurium isolates from poultry is resistant to penicillin. Methods: Teucrium polium extract using vacuum from the center (Rotary) were 12 strains of Salmonella typhimurium was isolated from poultry in the city of Zabol. Minimum inhibitory concentrations of MBC Teucrium polium extract in different concentrations by dilution in the wells was determined on bacteria. Susceptibility to several antibiotics by Kirby-Bauer disk diffusion standard were evaluated. Results: The result of herbal extraction showed the most MIC (the minimum inhibitory concentration) was 10mg/ml concentration that 2 strains of them were inhibited by this concentration Teucrium polium. The lowest MIC was 2/5 ppm concentration that two strain of Salmonella were inhibited. Although the clinical relevance of extracts and essential oils because of fewer side effects than other current treatments for common antibiotics, it seems valuable, but more research to clinical application of the mechanism of action of ethanol extract and purified effective composition of this plant is on microbial agents.
