Koubaa-Ghorbel F, Chaâbane M, Jdidi H, Turki M, Makni-Ayadi F, El Feki A. Salvia officinalis mitigates uterus and liver damages induced by an estrogen deficiency in ovariectomized rats. J Food Biochem 2020; 45:e13542. [PMID: 33124046 DOI: 10.1111/jfbc.13542] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 09/10/2020] [Accepted: 10/07/2020] [Indexed: 02/06/2023]
Abstract
The present study evaluated the antioxidant activity of Salvia officinalis (sage) and its protective effect on estrogen deficiency in ovariectomized rats. Female Wistar rats were treated during either 15 or 30 days as follows: group C: negative controls, group S: positive controls treated with sage leaves, ovariectomized rats (group OVX) and ovariectomized rats receiving either sage (OVX-S) or hormonal (Group OVX-E) treatments, respectively. After 15 and 30 days of treatments, OVX rats showed a gain in body weight and an increase of absolute and relative liver weights. Meanwhile, absolute and relative uterus weights were decreased. Moreover, ovariectomy altered plasma transaminases' activities, lipid profile, and disrupted the redox status of liver and uterine tissues. It affected also the reproductive tract by decreasing the uterus glycogen content and plasma LDH activity. Supplementation of sage via the diet reduced weight gain and oxidative stress resulting from estrogen deficiency. PRACTICAL APPLICATIONS: During menopause, sexual hormone deficiency, especially estrogen, causes several morphological and physiological disturbances in liver and uterus tissues. In fact, the body weight gain and disturbances of redox status in liver and uterus were the main health problems detected after menopause. Sage leaves, used as medicinal plant, exerted its beneficial effects in the management of menopause disorders. As an important source of antioxidants, sage leaves could prevent obesity and oxidative damage in the liver and uterus resulting from estrogen deficiency.

Serum Malondialdehyde is Associated with Non-Alcoholic Fatty Liver and Related Liver Damage Differentially in Men and Women. Antioxidants (Basel) 2020; 9:antiox9070578. [PMID: 32630732 PMCID: PMC7401879 DOI: 10.3390/antiox9070578] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 06/16/2020] [Accepted: 06/25/2020] [Indexed: 12/14/2022] Open
Abstract
Background: Non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) are associated with increased oxidative stress and lipid peroxidation, but large studies are lacking. The aim was to test the association of malondialdehyde (MDA), as a marker of oxidative damage of lipids, with NAFLD and liver damage markers, and to test the association between dietary vitamins E and C intake and MDA levels. Methods: A cross-sectional study was carried out among subjects who underwent blood tests including FibroMax for non-invasive assessment of NASH and fibrosis. MDA was evaluated by reaction with Thiobarbituric acid and HPLC-fluorescence detection method. NAFLD was diagnosed by abdominal ultrasound. Findings: MDA measurements were available for 394 subjects. In multivariate analysis, the odds for NAFLD were higher with the rise of MDA levels in a dose–response manner, adjusting for age, gender, BMI, and lifestyle factors. Only among men, higher serum MDA was associated of higher odds for NAFLD and NASH and/or fibrosis (OR = 2.59, 95% CI 1.33–5.07, P = 0.005; OR = 2.04, 1.02–4.06, P = 0.043, respectively). Higher vitamin E intake was associated with lower odds of high serum MDA level (OR = 0.28 95% CI 0.13–0.62, P = 0.002). In conclusion, serum MDA is associated with NAFLD and markers of NASH or fibrosis among men. Dietary vitamin E may be protective among women.

Intraoviductal concentrations of steroid hormones during in vitro culture changed phospholipid profiles and cryotolerance of bovine embryos. Mol Reprod Dev 2019; 86:661-672.

Abstract
The objective of this study was to evaluate the effect of progesterone (P4), estradiol (E2), and cortisol (CO) at intraoviductal concentrations on bovine embryo development and quality in vitro. After fertilization of in vitro matured oocytes, zygotes were cultured for 8 days in synthetic oviductal fluid, supplemented with 55 ng/ml P4, 120 pg/ml E2, 40 ng/ml CO, or their combination (ALL). Control embryos were cultured with vehicle (0.1% ethanol). Exposure to steroids did not affect the embryo developmental rate nor the mean number of cells per blastocyst. However, at 24 hr after vitrification-warming, exposure to P4 improved the proportion of embryos that re-expanded and were viable while exposure to CO decreased the proportion of viable embryos. By intact cell MALDI-TOF mass spectrometry, a total of 242 phospholipid masses of 400-1000 m/z were detected from individual fresh blastocysts. Exposure to ALL induced the highest and most specific changes in embryo phospholipids, followed by P4, E2, and CO. In particular, the m/z 546.3 and 546.4 attributed to lysophosphatidylcholines were found less abundant after exposure to P4. In conclusion, exposure of bovine embryos to intraoviductal concentrations of steroid hormones did not affect in vitro development but changed blastocyst quality in terms of cryotolerance and phospholipid profiles.

Abstract
Cytochrome P450 aromatase (encoded by the CYP19A1 gene) regulates oestrogen biosynthesis and so plays an essential role in female fertility. We investigated the genetic association of CYP19A1 with the risk of anoestrus in Egyptian water buffaloes. A total of 651 animals (326 anoestrous and 325 cycling) were used in this case-control study. Using single-strand conformation polymorphisms and sequencing, four single nucleotide polymorphisms (SNPs) were detected; c.−135T > C SNP in the 5′UTR and three non-synonymous SNPs: c.559G > A (p. V187M) in Exon 5, c.1285C > T (p. P429S) and c.1394A > G (p. D465G) in Exon 10. Individual SNP-anoestrus association analyses revealed that genotypes (CC, AA and GG) and alleles (C, A and G) of the −135T > C, c.559G > A and c.1394A > G SNPs respectively were high risk for anoestrus. A further analysis confirmed that these three SNPs were in linkage disequilibrium. Additionally, haplotypes with two (TAG/122 and CAA/221) or three (CAG/222) risk alleles were significantly associated with susceptibility to anoestrus, lower blood levels of both oestradiol and antioxidant enzymes (superoxide dismutase, glutathione peroxidase (GPX) and catalase) and downregulated expression levels of CYP19A1, oestrogen receptor α and Gpx3 in the ovary, as well as increased serum level of malondialdehyde. This suggests the occurrence of a high incidence of oxidative ovarian damage and subsequently ovarian inactivity in buffaloes carrying risk alleles. Therefore, with this study we suggest the selection of buffaloes with protective alleles at these SNPs to improve the reproductive efficiency of the herd.

Abstract
BACKGROUND A link between lipid metabolism and disease has been recognized in cats. Since hepatic lipidosis is a frequent disorder in cats, the aim of the current study was to evaluate liver and plasma lipid dimorphism in healthy cats and the effects of gonadectomy on lipid profiling. From six female and six male cats plasma and liver lipid profiles before and after spaying/neutering were assessed and compared to five cats (three neutered male and two spayed female) diagnosed with hepatic lipidosis. RESULTS Intact female cats had a significantly lower level of plasma triacylglycerides (TAG) and a higher liver level of the long chain polyunsaturated fatty acid arachidonic acid (AA) compared to their neutered state. Both male and female cats with lipidosis had a higher liver, but not plasma TAG level and an increased level of plasma and liver sphingomyelin compared to the healthy cats. CONCLUSION Although lipid dimorphism in healthy cats resembles that of other species, intact female cats show differences in metabolic configuration that could predispose them to develop hepatic lipidosis. The increased sphingomyelin levels in cats with lipidosis could suggest a potential role in the pathogenesis of hepatic lipidosis in cats.

Abstract
The purpose of this study was to investigate the effects of hawthorn (Crataegus pinnatifida Bunge) extract on the lipid profiles and antioxidant properties in ovariectomized (OVX) rats. After ovariectomy, the rats were randomly divided into four groups: the non-OVX control (Sham), the OVX-control (OVX), the OVX + 100 mg/kg b.w. of hawthorn extract (OL), and the OVX + 200 mg/kg b.w. of hawthorn extract (OH). The final body weights of the OVX group were significantly increased, but the increment was significantly decreased in hawthorn groups (p < 0.05). The serum total and low-density lipoprotein (LDL) cholesterol levels were significantly elevated in the OVX group, whereas the hawthorn groups showed a significant decrease in these levels (p < 0.05). The hepatic triglyceride (TG) and malondialdehyde (MDA) levels were significantly reduced in the hawthorn groups compared with the OVX group (p < 0.05). The mRNA expression of nuclear factor erythroid 2–related factor (Nrf2), heme oxygenase-1 (HO-1), and glutathione peroxidase (GPx) were significantly decreased in the OVX group, whereas the hawthorn groups exhibited a significant increase in expression (p < 0.05). The protein expressions of Nrf2, HO-1, and GPx were lower in the OVX group than the Sham group (p < 0.05). The oral administration of hawthorn extract reversed the suppression of protein levels. These results suggest that hawthorn extract could have protective effects in OVX rats by improving lipid profiles, decreasing oxidative stress, and improving the antioxidant defense system.

Abstract
Estrogens, with their principle representative 17β-estradiol, contribute to the redox state of cells showing both pro- and antioxidative properties. In the ovary, being the main source of estrogens, maintaining balance between the production and detoxification of ROS is crucial. Whereas ovary estrogen concentration is difficult to estimate, its circulating concentration in women may reach the nanomolar level. The aim of the study was to evaluate the effects of 17β-estradiol on oxidative damage to membrane lipids (lipid peroxidation, LPO) and to nuclear DNA in the porcine ovary under basal conditions and in the presence of Fenton reaction (Fe(2+)+H2O2→Fe(3+)+(•)OH + OH(-)) substrates. Ovary homogenates and DNA were incubated in the presence of 17β-estradiol (1 mM-1 pM), without/with FeSO4 (30 μM) + H2O2 (0.5 mM). Malondialdehyde + 4-hydroxyalkenals (MDA + 4-HDA) concentration (LPO index) was measured spectrophotometrically. The concentration of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) (DNA damage index) was measured by HPLC. We observed that 17β-estradiol did not alter the basal level of oxidative damage, but reduced Fe(2+)+H2O2-induced oxidative damage to membrane lipids when ≥10 nM and to DNA at concentrations ≥1 nM. In the ovary at near physiological concentration, 17β-estradiol prevents experimentally induced oxidative damage. This suggests that under physiological conditions this hormone may contribute to protecting the ovary against oxidative damage.

Abstract
The effects of 8-days treatment with 17alpha-estradiol (33.3 microg/kg) and progesterone (1.7 mg/kg) on plasma lipids and fatty acid composition of plasma phospholipids were examined in intact (INT) and bilaterally common carotid arteries occluded (BCO) male Wistar rats. Significant decrease of triglyceride level was found in BCO rats after the estradiol treatment. Both hormones elevated proportion of 18:1n-7 fatty acid in INT, but they failed to have such an effect in BCO. Estradiol increased 22:5n-3 and total n-3 polyunsaturated fatty acids (PUFA) in intact, and decreased 18:2n-6 in BCO rats. Significantly lower level of total n-3 was found in progesterone-treated than in estradiol-treated BCO rats. Given that n-3 PUFA have many beneficial effects on cell and tissue function, while n-6 PUFA have mostly the opposite effects, estradiol, rather than progesterone, was seen to improve plasma lipids and phospholipids FA profiles in INT and BCO animals. Estradiol significantly elevated the estimated activity of delta9-desaturases and progesterone of delta5-desaturase in BCO group, with no effects in INT rats.

Abstract
Acupoint stimulations are effective in ameliorating symptoms of menopause which is an unavoidable ageing consequence for women. To understand the mechanistic aspects of such treatments, we systematically analyzed the effects of acupoint laser-irradiation and catgut-embedding on the ovariectomy-induced rat metabolic changes using NMR and GC-FID/MS methods. Results showed that ovariectomization (OVX) caused comprehensive metabolic changes in lipid peroxidation, glycolysis, TCA cycle, choline and amino acid metabolisms. Both acupoint laser-irradiation and catgut-embedding ameliorated the OVX-caused metabonomic changes more effectively than hormone replacement therapy (HRT) with nilestriol. Such effects of acupoint stimulations were highlighted in alleviating lipid peroxidation, restoring glucose homeostasis and partial reversion of the OVX-altered amino acid metabolism. These findings provided new insights into the menopause effects on mammalian biochemistry and beneficial effects of acupoint stimulations in comparison with HRT, demonstrating metabonomics as a powerful approach for potential applications in disease prognosis and developments of effective therapies.

Bilateral ovariectomy in young rats: what happens in their livers during cecal ligation and puncture induced sepsis? J Pediatr Adolesc Gynecol 2012; 25:371-9. [PMID: 23089572 DOI: 10.1016/j.jpag.2012.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2012] [Revised: 07/06/2012] [Accepted: 07/11/2012] [Indexed: 11/23/2022]
Abstract
STUDY OBJECTIVE Pediatric ovarian masses comprise a heterogeneous group of benign and malignant lesions. Surgical methods consist of emergency or programmed surgery with tumoral resection and uni/bilateral oophorectomy or salpingo-oophorectomy. We examined whether bilateral ovariectomy (OVX) worsens liver injury during the onset of cecal ligation and puncture (CLP)-induced sepsis in rats. DESIGN The rat groups were: sham, bilateral-OVX, sepsis, and OVX-sepsis. SETTINGS After OVX operation, rats were allowed to recover for 12 weeks. At the end of recovery, CLP was applied 16 hours after sepsis induction. MAIN OUTCOME There was a significant difference in the numerical density of hepatocytes only between the sepsis and the OVX-sepsis groups. Serum ALT and AST were increased significantly in the OVX-sepsis group. NF-κB activation after OVX increased after induction of sepsis. OVX-sepsis group showed marked thrombosis in portal vein branches and the central vein, degeneration in the bile ducts, and widespread ischemic areas in liver sections. Intra-inflammatory cell invasion was observed in both the portal and intrasinusoidal areas. DISCUSSION This study indicates that increases in liver NF-κB activity in ovariectomized rats following CLP-induced sepsis correlates with elevated levels of serum ALT and AST and with histopathologic changes in rat liver. Bilateral OVX therefore appears to play a role in the activation of NF-κB or in production of cytokines in liver cells. Thus, we provided novel insight into the effects of OVX on liver injury following CLP-induced sepsis.

Abstract
The aim of this study was to investigate the effects of vitamin E (alpha-tocopherol) and 17β-estradiol (E(2)) supplementation on malondialdehyde (MDA), glutathione (GSH), vitamin A, beta carotene, selenium-dependent glutathione peroxidase (GSH-Px), zinc-dependent superoxide dismutase (SOD), and copper/zinc-dependent catalase (CAT) values in the kidney of ovariectomized (OVX) diabetic rats. Forty-two female rats were randomly divided into seven equal groups as follows: group I, control; group II, OVX; group III, OVX+E(2); group IV, OVX+E(2)+alpha-tocopherol; group V, OVX+diabetic; group VI, OVX+diabetic+E(2); and group VII, OVX+diabetic+E(2)+alpha-tocopherol. E(2) (40 μg kg(-1)/day) and alpha-tocopherol (100 μg kg(-1)/day) were given. Bilateral ovariectomy was performed in all groups except group I. After 4 weeks, antioxidant and MDA levels in the kidney for all groups were analyzed. GSH-Px, CAT, SOD, GSH levels, vitamin A, and beta carotene levels were decreased in OVX group compared to those in the control group but MDA level was elevated via ovariectomy. However, E(2) and E(2)+alpha-tocopherol supplementations in OVX group was associated with an increase in the GSH-Px, GSH, CAT and Zn-SOD values, vitamin A, and beta carotene levels but a decrease in MDA levels in kidney. The MDA levels in the kidney of diabetic OVX rats were found higher than those in the control and OVX groups. However, GSH, GSH-Px, CAT, SOD, vitamin A, and beta carotene levels in kidney were lower in OVX diabetic rats. On the other hand, E(2) and E(2)+alpha-tocopherol supplementations to OVX diabetic rats have caused an increase in GSH-Px, CAT and SOD, GSH, vitamin A, and beta carotene levels but a decrease in MDA levels. In conclusion, the E(2) and E(2)+alpha-tocopherol supplementations to diabetic OVX and OVX rats may strengthen the antioxidant defense system by reducing lipid peroxidation, and therefore they may play a role in preventing renal disorders.

Abstract
The prevalence of insulin resistance syndrome increases during menopause with the overproduction of reactive oxygen species and impairment of the free radical scavenger function. Therefore, we investigated the effects of 17β-estradiol (E2) and vitamin E, as an antioxidant, on lipid peroxidation and antioxidant levels in the brain cortex and liver of ovariectomized rats as well as on insulin resistance in those rats. Forty female Sprague–Dawley rats, 3 months of age and weighing 231.5 ± 9.4 g, were divided into 4 groups: sham, ovariectomized (OVX), OVX treated with E2 (40 µg/kg subcutaneously), and OVX treated with E2 and vitamin E (100 mg/kg intraperitoneally). The 4 groups received the appropriate treatment every day for 8 weeks. Levels of glutathione, glutathione peroxidase, superoxide dismutase , catalase, and malondialdehyde in the brain cortex and liver of ovariectomized rats were measured. Also, fasting plasma insulin, glucose, and homeostatis model assessment of insulin resistance (HOMA-IR) were determined. Malondialdehyde increased and antioxidants (glutathione, glutathione peroxidase, catalase, superoxide dismutase) decreased in the brain cortex and liver of OVX rats. Also, fasting glucose, insulin, and HOMA-IR increased in OVX rats. E2 and E2 plus vitamin E decreased malondialdehyde and increased antioxidants in the brain cortex and liver of OVX rats. Moreover, they decreased fasting glucose, insulin, and HOMA-IR in ovariectomized rats. This study demonstrates that E2 and E2 plus vitamin E supplementation to OVX rats may improve insulin resistance, strengthen the antioxidant system, and reduce lipid peroxidation.

Abstract
The present study investigated whether diabetes worsened the onset of liver injury/damage during the ovariectomized (OVX)-induced postmenopausal period in rats. Diabetes results in severe complications in humans, such as liver failure. Estrogen and its derivatives are medically acceptable, powerful antioxidant agents that can enable liver and other important organs to defend themselves against oxidative related injury. Estrogen deficiency, which occurs in the postmenopausal period and in individuals with diabetes, may play a significant role in the progression of liver failure. In the present study, rats were divided into four groups: control (Group I), diabetic (Group II), ovariectomy (Group III) and ovariectomy plus diabetes (Group IV). After the experiments, quantitative histopathological and immunohistochemical changes in liver were detected using light microscopy and modern stereological systems. Histopathological examinations showed that there were many necrotic and apoptotic hepatocytes in the lobules of Group II. In addition, there were a larger number of necrotic cells in Group III than Group II. In contrast to Group II, there were also apoptotic cells in the portal areas in Group III. Moreover, evidence of liver injury was higher in the sections of Group IV compared with all other groups. In biochemical findings, there were statistically significant differences between all the groups (P < 0.001) for catalase (CAT), glutathione peroxidase (GSH) and myeloperoxidase (MPx) activity. In addition, the amount of lipid peroxidation (LPO) was significantly different between groups. In stereological results, there were significant differences between Groups I and II and Groups II and IV. The present study provided novel insight into the pernicious effects of ovariectomy on liver injury following the onset of diabetes. Indeed, the present study found that increases in liver oxidative activity in OVX rats following the onset of diabetes correlates with elevated MPx, LPO and histopathological changes in rat liver.

Abstract
The aim of the study was to determine the influence of ovariectomy on phase II enzymes viz. glutathione-S-transferase (GST), glutathione peroxidase (GPX) and catalase (CAT) in liver and kidney of female rats treated with benzene. The results showed the significant decrease of the GST and GPX activity in benzene treated rats after ovariectomy. However progesterone supplementation stimulated the activity of GST and GPX in liver and kidney of benzene treated non ovariectomized and ovariectomized rats. Progesterone supplementation to benzene treated ovariectomized rats helps to gain in CAT activity. Our results on DNA damage using single cell gel electrophoresis also confirmed our findings on antioxidant enzymes. The results showed that lack of protective progesterone against benzene toxicity is reflected in alterations in antioxidant enzyme activities. However progesterone therapy to benzene treated ovariectomized rats results in activating the antioxidant defence system. Since female workers are engaged in industrial sector, these results are important from occupational health point of view. Benzene exposure affects their reproductive health. Nevertheless, it could be modulated by suitable hormonal therapy.

Abstract
Abstract
Objectives
Ovarian hormone decline after menopause is linked to many pathophysiological reactions. Female rats submitted to ovariectomy are employed as a model of post-menopausal condition. This study investigated the effects of diphenyl diselenide (PhSe)2 on body weight gain, intra-abdominal fat deposition, plasma lipid profile and hepatic oxidative stress in ovariectomized rats.
Methods
Female adult Wistar rats were ovariectomized (OVX rats) or sham-operated and divided into four groups: (i) sham-operated, (ii) (PhSe)2, (iii) OVX and (iv) OVX + (PhSe)2. (PhSe)2 (5 mg/kg; 5 ml/kg, p.o.) was administered once a day for 30 days to groups (ii) and (iv). After that, rats were anaesthetized for blood sample gathering and submitted to euthanasia.
Key findings
(PhSe)2 (5 mg/kg) was effective in preventing the rise in body weight gain and intra-abdominal fat deposition induced in OVX rats. Although (PhSe)2 was not effective in avoiding the increase in plasma total cholesterol and non-HDL levels induced in OVX rats, (PhSe)2 reduced plasma triglycerides and augmented HDL levels in OVX rats. (PhSe)2 also increased hepatic ascorbic acid levels, reduced glutathione content, glutathione S-transferase activity and restored catalase activity in liver of OVX rats.
Conclusions
These findings suggest that (PhSe)2 could be a promising alternative to minimize menopause related symptoms.

Abstract
OBJECTIVES Sepsis model was used to understand the role of sustained hyperglycemia and ovariectomy, either separately or concomitantly, on the response of the activity of the nuclear factor kappa B (NF-kappaB) and the oxidative response in kidney. SUBJECTS Polymicrobial sepsis was induced by cecal ligation and puncture (CLP). Diabetes was induced in female rats using administration of alloxan. The rats were divided into five groups: sham control (group 1), ovariectomy (group 2), ovariectomy + sepsis (group 3), ovariectomy + diabetes (group 4), and ovariectomy + diabetic + sepsis (group 5). RESULTS In kidney tissues, the levels of lipid peroxidation (LPO) and glutathione (GSH) and the activity of catalase (CAT) were higher for groups 3, 4, 5 than the control groups. Superoxide dismutase (SOD) activity was lower for groups 3, 4, 5 than the control groups. We determined that CLP produced injury evident in the kidneys of rats when compared to the control group, whereas the severity of the injury was higher in the diabetes + ovariectomy + CLP group when compared to the CLP group. In immunohistochemical staining, we determined that CLP operation increased NF-kappaB activation. In the ovariectomized, septic, and diabetic group, NF-kappaB activation was significantly higher than other groups. CONCLUSIONS Hyperglycemia and ovariectomy severely increased NF-kappaB activation and oxidant levels with the stages of our sepsis model. Ovariectomy resulted in general changes in metabolism, which are seen in the kidney with diabetes under sepsis conditions.

Abstract
We investigated the effects of 17beta-estradiol (E 2 ) and vitamin E on lipid peroxidation and antioxidant levels in brain cortex of diabetic ovariectomized (OVX) rats. Forty-two rats were equally divided into seven groups: Control; OVX; OVX+E 2 ; OVX+E 2 +vitamin E; OVX+diabetic; OVX+diabetic+E 2 and OVX+diabetic+E 2 +vitamin E. Then, E 2 (40 microg kg -1 /day) and vitamin E (100 mg kg -1 /day) were given. Glutathione peroxidase (GSH-Px), catalase (CAT), superoxide dismutase (SOD), glutathione (GSH), vitamin A and beta-carotene in brain were decreased (p<0.05) when compared with control in OVX but MDA in brain and glucose in plasma were elevated (p<0.05). The antioxidant levels in brain (p<0.05) increased although MDA (p<0.05) in brain and glucose (p<0.05, p<0.01) in plasma decreased in OVX after E 2 and E 2 +vitamin E supplementation. The activities of GSH-Px (p<0.001, p<0.01), CAT (p<005, p<0.001) and SOD (p<0.001) and the levels of GSH (p<0.001), vitamin A (p<0.05) and beta-carotene (p<0.001, p<0.05) were lower in the brain of OVX diabetic rats, while MDA in the brain and glucose in the plasma were higher (p<0.001). The antioxidant enzymes (p<0.05, p<0.01), GSH, vitamin A and beta-carotene (p<0.01, p<0.001) in brain increased while MDA in brain and glucose in plasma decreased (p<0.01, p<0.001) in diabetic OVX after treatments. Finally, the E 2 and E 2 +vitamin E supplementation to diabetic OVX and OVX rats may strengthen the antioxidant system by reducing lipid peroxidation.
