Abstract
OBJECTIVE The protective effect of aqueous and methanolic extracts of corn silk on reproductive disorders induced by nicotine was investigated in the present study. METHODS In this experimental study, 30 male NMRI mice (25-30gr) were divided into 5 groups: controls, sham, nicotine 2.5mg/kg, nicotine+aqueous extract of corn silk 400mg/kg, and nicotine+methanolic extract of corn silk 400mg/kg for 34 days. One day after the last nicotine and extracts administration, the serum samples were collected through cardiac puncture for hormonal measurements, and the testis and tail of the epididymis were isolated for the testis antioxidant, morphology, histopathology assessments, and sperm count. RESULTS Luteinizing hormone (LH) and malondialdehyde (MDA) increased in the nicotine group. Testosterone, sperm count, and glutathione (GSH) decreased when compared to the control group. Both aqueous and methanolic extracts of corn silk led to the improvement of mentioned changes; Except for GSH, because only treatment with methanolic extract could lead to its increase (p<0.05). Nicotine decreased the thickness of the epithelium of seminiferous tubules and the separation between them, and the administration of corn silk extracts improved that. CONCLUSIONS Nicotine consumption increased oxidative stress, LH levels, and decreased testosterone and sperm count, which indicate the induction of primary hypogonadism in animals. Moreover, the use of corn silk extracts has recovered the amounts of sex hormones and sperm count to normal conditions by reducing lipid peroxidation.

Abstract
Background and objective Some individuals report a near-death experience (NDE) after a life-threatening crisis, which refers to a range of subjective experiences related to impending death. This experience is a phenomenon with transcendental elements, which leads to deep permanent changes in both the individual and the social lives of the NDEr's. Therefore, this study aims to review the near-death experiences of individuals with different religious and cultural views. Methodology This is a systematic analysis study. All the case report, case series and qualitative research studies which presented patients' NDE experiences were included in the study, without language restrictions, and in the period of 1980-2022. The stages of screening, selection, data extraction, and quality assessment have been gone through by two of the researchers. Data analysis and synthesis has been done qualitatively. JBI Critical Appraisal Checklist tool was used to evaluate the quality of the included studies. Findings After the initial search, 2,407 studies were included, 54 of which underwent final examination. The total number of the NDEr's in the studies was 465 men, women, and children. Among these studies, 27 were case reports, 20 were case series, and 7 were qualitative studies. Near-death experiences have been categorized into 4 main categories and 19 subcategories. The main categories include emotional experiences (2 subcategories), cognitive experiences (4 subcategories), spiritual and religious experiences (4 subcategories), and supernatural experiences [9 subcategories in two categories (out of body experiences, and supernatural and metaphysical perceptions)]. Conclusion The most frequent near-death experiences were supernatural experiences, especially the experience of leaving the body. The basis and the content of the patterns mentioned by the NDEr's are similar, and the differences are in the explanation and the interpretation of the experience. There is a common core among them such as out-of-body experiences, passing through a tunnel, heightened senses, etc. Therefore, correct knowledge of near-death experiences leads to providing helpful answers to patients.

Abstract
BACKGROUND This study aimed to systematically review and pool data regarding the alterations in the clinical course of inflammatory bowel disease (IBD) following liver transplantation (LT). METHODS Relevant prospective and retrospective observational studies were identified by searching databases and gray literature through December 2020. Random-effects models were used to calculate the pooled frequency of IBD patients with disease course alterations ("improved," "unchanged," or "aggravated") after LT and the corresponding 95% confidence intervals (CIs). RESULTS Twenty-five studies met our inclusion criteria, reporting the outcomes in 2 or 3 categories. In the analysis of studies with 3-category outcomes (n = 13), the pooled frequencies of patients with improved, unchanged, or aggravated IBD course after LT were 29.4% (95% CI, 16.9% to 41.9%), 51.4% (95% CI, 45.5% to 57.3%), and 25.2% (95% CI, 15.6% to 34.8%), respectively. Subgroup analyses revealed that patients with ulcerative colitis (UC), younger age at LT, or shorter duration of follow-up were more likely to have an improved disease course. Moreover, higher IBD exacerbation estimates were observed in studies with a low risk of bias. In the analysis of studies with 2-category outcomes (n = 12), the pooled frequencies of patients with improved/unchanged or aggravated IBD course were 73.6% (95% CI, 62.2% to 85.0%) and 24.1% (95% CI, 15.1% to 33.2%), respectively. The cumulative incidence of an exacerbated IBD course following LT was 0.22 (95% CI, 0.16-0.29; P < .001). CONCLUSION We conclude that IBD activity remains unchanged (or improved/unchanged) in most IBD patients following LT. Furthermore, IBD type, age, and follow-up length can influence the IBD course after LT.

Abstract
CONTEXT The hyperglycemia (Hyper) induces oxidative stress in kidney tubular cells. Myricitrin (Myr) has an antioxidant effect along with low bioavailability. OBJECTIVE The present research investigated the effects of Myr and its solid lipid nanoparticles (SLN) on isolated proximal tubules exposed to the hyperglycemic condition. MATERIALS AND METHODS In this experimental study, the proximal tubules of mice were dissected by the microdissection method and the tubules were prepared for experimental or Real Time-PCR measurement. RESULTS The malondialdehyde level, transforming growth factor-β, nuclear factor kappa B and Bax genes expression increased in Hyper and decreased in Hyper + Myr and its SLN-treated groups compared to Hyper. Superoxide dismutase, total antioxidant capacity, the viability of proximal tubules and Bcl-2 gene expression decreased in untreated Hyper and increased in all treatment groups compared to Hyper. CONCLUSION The hyperglycemia-induced oxidative disorder, inflammation and apoptosis in proximal tubules and that administrating Myr and its SLN improved them.

Abstract
Increasing applications of carbon nanotubes (CNTs) indicate the necessity to examine their toxicity. According to previous studies, CNTs caused oxidative stress that impaired β-cell functions and reduced insulin secretion. Our previous study indicated that single-walled carbon nanotubes (SWCNTs) could induce oxidative stress in pancreatic islets. However, there is no study on the effects of multi-walled carbon nanotubes (MWCNTs) on islets and β-cells. Therefore, the present study aims to evaluate effects of MWCNTs on the oxidative stress of islets and the protective effects of caffeic acid (CA) as an antioxidant. The effects of MWCNTs and CA on islets were investigated using MTT assay, reactive oxygen species (ROS), malondialdehyde (MDA), activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), the content of glutathione (GSH) and mitochondrial membrane potential (MMP) and insulin secretion measurements. The lower viability of islet cells was dose-dependent due to the exposure to MWCNTs according to the MTT assay. Further studies revealed that MWCNTs decreased insulin secretion and MMP, induced ROS creation, increased the MDA level, and decreased activities of SOD, GSH-Px, CAT, and content of GSH. Furthermore, the pretreatment of islets with CA returned the changes. These findings indicated that MWCNTs might induce the oxidative stress of pancreatic islets occurring diabetes and protective CA effects that were mediated by the augmentation of the antioxidant defense system of islets. Our research suggested the necessity of conducting further studies on effects of MWCNTs and CA on the diabetes.

Abstract
Objective: Obesity is associated with reproductive disorders. Arsenic disrupts male reproduction by direct effects on the male gonads or androgens secretion. So, the present study was conducted to evaluate the toxic effects of chronic concomitant administration of high-fat diet (HF) and arsenic on the reproductive system of the male mouse.
Materials and methods: In this experimental study, 72 adult male mice were randomly divided into 6 groups: low-fat diet (LF0), LF+arsenic 25 ppm, LF+arsenic 50ppm, HF0, HF+arsenic 25 ppm and, HF+arsenic 50 ppm. 24 hours after the last experimental day, plasma samples, the cauda of epididymis and testis were prepared and removed for hormonal, sperm count and histopathological assessments.
Results: Testis weight and volume increased in HF0 than other groups except for LF0. Plasma LH and testosterone levels decreased in LF50, HF0, HF25, and HF50 compared to LF0. A similar effect was observed in plasma FSH levels of HF0, HF25 and HF50 groups compared with LF0. Plasma level of estradiol increased in LF50 versus to other groups. Testosterone to estradiol ratio and sperm count decreased in all groups compared to LF0. Reduced interstitial cells and large numbers of vacuoles were observed in germinal epithelium of HF0 group, that these changes were more intense in both concentrations of arsenic-treated mice.
Conclusion: Present study indicated that chronic exposure to HF and arsenic-induced hypogonadotropic hypogonadism concomitant with sperm count reduction and testicular damage.

Abstract
Glucose homeostasis is required for control of insulin secretion. Phenolic compounds improved glucose-stimulated insulin secretion (GSIS). Eugenol is a phenolic compound that may increase GSIS. So, it was decided to investigate the effect of eugenol on the insulin secretion and content of pancreatic islets from the male mice. In this experimental study, 3-month-old NMRI mice (20-25 g) were prepared. The pancreatic islets of Langerhans were isolated using the collagenase digestion method and divided into 12 groups: glucose 2.8, 5.6, and 16.7 mM, glucose 2.8 mM + eugenol 50, 100, and 200 µM, glucose 5.6 mM + eugenol 50, 100, and 200 µM, and glucose 16.7 mM + eugenol 50, 100, and 200 µM. The islet's insulin secretion and content were measured after 1 hour and 24 hours incubation at 37°C, respectively, by the ELISA assays method and related commercial kit. Present results showed that all doses of eugenol increased islet's insulin secretion and content in the medium containing glucose concentrations 2.8, 5.6, and 16.7 mM (P < 0.05). In conclusion, eugenol as a phenolic compound increased insulin secretion and content of pancreatic islets. The moderate dose of this compound enhanced insulin secretion during hypo- and hyperglycemic conditions, as well as a high dose of eugenol, increased insulin content. Finally, present research suggested that the administration of eugenol 100 µM was suitable for the early stage of T2DM as well as eugenol 200 µM for the advanced stage of this disease.

Abstract
Purpose The present study investigates the effects of myricitrin and solid lipid nanoparticle (SLN) containing myricitrin on the reproductive system of type 2 diabetic male mice. Materials and Methods In this experimental study, SLN containing myricitrin was prepared by the cold homogenization method. Then, 90 adult male Naval Medical Research Institute mice were divided into 9 groups (n=10): control, vehicle, diabetic, diabetic+myricitrin or SLN containing myricitrin 1, 3, and 10 mg/kg. Diabetes was induced by streptozotocin (65 mg/kg) 15 minutes after nicotinamide (120 mg/kg) injection. Myricitrin and SLN containing myricitrin administered during 1 month. At the 34th days of the experiment, plasma and tissue samples were taken for experimental assessments. Results Testis weight and volume decreased in the diabetic group. These variables increased in diabetic treated mice by a high dose of myricitrin or all doses of SLN containing myricitrin (p<0.05). Total antioxidant capacity and superoxide dismutase levels decreased in diabetic mice, and administration of myricitrin 10 mg/kg or all doses of SLN containing myricitrin increased them (p<0.05). Luteinizing hormone, Follicle-stimulating hormone, testosterone, and sperm count decreased in the diabetic group, treatment with a high dose of myricitrin or all doses of SLN containing myricitrin recovered them (p<0.05). Diabetes induced vacuoles and apoptosis in testicular cells, meanwhile myricitrin and SLN containing myricitrin improved them (p<0.05). Conclusions Diabetes induced reproductive problem via increased oxidative stress and decrease antioxidant capacity, administration of myricitrin or SLN containing myricitrin improved them. Further, SLN containing myricitrin was more potent than myricitrin.

Materials and methods: In this experimental study, 72 adult male mice were randomly divided into 6 groups: low-fat diet (LF0), LF+arsenic 25 ppm, LF+arsenic 50ppm, HF0, HF+arsenic 25 ppm and, HF+arsenic 50 ppm. 24 hours after the last experimental day, plasma samples, the cauda of epididymis and testis were prepared and removed for hormonal, sperm count and histopathological assessments. Results: Testis weight and volume increased in HF0 than other groups except for LF0. Plasma LH and testosterone levels decreased in LF50, HF0, HF25, and HF50 compared to LF0. A similar effect was observed in plasma FSH levels of HF0, HF25 and HF50 groups compared with LF0. Plasma level of estradiol increased in LF50 versus to other groups. Testosterone to estradiol ratio and sperm count decreased in all groups compared to LF0. Reduced interstitial cells and large numbers of vacuoles were observed in germinal epithelium of HF0 group, that these changes were more intense in both concentrations of arsenic-treated mice. Conclusion: Present study indicated that chronic exposure to HF and arsenic-induced hypogonadotropic hypogonadism concomitant with sperm count reduction and testicular damage.

Abstract
OBJECTIVE To evaluate the hydroethanolic extract toxicity, obtained from Tropaeolum majus L. (TM) on mouse testicular tissue. METHOD In this experimental study, we used 32 male NMRI mice. The experimental groups received 75, 375 and 750 mg/kg of TM extract, respectively. Twenty-four hours after the last experimental day, serum samples were collected for hormonal measurement. Then, the cauda of epididymis and testis were removed for sperm count and histopathological assessments. RESULTS Testosterone serum and testicular levels decreased in 750 mg/kg in the treated group when compared to the control animals (1.65±0.25; p=0.041 and 98.83±8.67; p=0.034 respectively). Histopathological criteria such as epithelial vacuolization (9.3±1.1; p=0.034), sloughing (4.3±0.4; p=0.027) and detachment (12.2±0.9; p=0.031) of germ cells were significantly increased in 750 mg/kg in the treated mice. In addition, there were no significant changes in histopathological criteria; sperm head numbers, Johnsen's scoring, and morphometry assessments were carried out in the 75 and 375 mg/kg treated mice. At the dose of 750 mg/kg, the seminiferous tubule diameter (193.2±4.6; p=0.019), seminiferous epithelium height (139.2±5.1; p=0.023), and maturation arrest were significantly decreased in this group. CONCLUSION In conclusion, TM extract has toxic effects on the mouse testicular tissue in high doses. Hence, we recommend caution concerning its consumption by patients with reproductive problems.

Abstract
Hyperglycemia induced oxidative stress inside the cells. Myricitrin, as an antioxidant plant-derived component, may be useful in hyperglycemia. Hence, the aim of this study was conducted to evaluate the antioxidant effects of myricitrin on hyperglycemia-induced oxidative damage in myotubes (C2C12 cells). In this experimental study, mouse myoblast cell line (C2C12) was obtained and divided into five groups: control, hyperglycemia, hyperglycemia + myricitrin 1, 3, and 10 μM. After treatment period for 48 h, cells were collected, homogenized, and centrifuged at 2000 rpm for 10 min. All samples were kept at - 80 °C until experimental and real-time PCR assessments were performed. Hyperglycemia increased malondialdehyde (MDA) (p < 0.05), total antioxidant capacity (TAC) (p < 0.001), and cellular apoptosis, and decreased levels of superoxide dismutase (SOD), catalase (CAT) (p < 0.01), myotube glycogen content (p < 0.05), glucose transporter type 4 (Glut-4), and cellular viability (p < 0.001). Myricitrin administration improved SOD (p < 0.05), CAT (p < 0.01), muscle cell's glycogen content (p < 0.01), Glut-4 gene expression (p < 0.001), Thiazolyl blue tetrazolium bromide (MTT) (p < 0.05), and Bax to Bcl-2 ratio (p < 0.001), and reduced MDA (p < 0.05) compared to hyperglycemia group. In conclusion, hyperglycemic condition induced oxidative stress along with cellular apoptosis, and myricitrin improved these disorders. Also, low and moderate doses of myricitrin are more efficient on skeletal muscle cells exposed to hyperglycemic statues than a high concentration of this antioxidant agent.

Abstract
The thyroid is one of the major endocrine glands that contribute to body and fat metabolism. The present study evaluated the effects of combined exposure to chronic high-fat diet (HFD) and arsenic on thyroid function and lipid profile. In this experimental study, 72 male Naval Medical Research Institute mice were divided into six groups and fed HFD or low-fat diet (LFD) while being exposed to 25 or 50 ppm of arsenic in drinking water for 20 weeks. After 24 h of the last experimental day, blood samples were collected for hormonal and biochemical measurements. The data indicated that exposure to HFD alone increased the levels of triiodothyronine (T3), thyroid-stimulating hormone (TSH), leptin, lipid profile, reactive oxygen species (ROS), and malondialdehyde (MDA) and decreased the levels of high-density lipoprotein, albumin, adiponectin, and glutathione sulfhydryl reductase (GSH), whereas exposure to arsenic alone decreased the levels of T3 and GSH and increased the levels of TSH, leptin, ROS, MDA, and T4/T3 ratio compared to those in the control LFD group. Furthermore, concomitant administration of HFD and arsenic decreased the lipid profile and levels of T4, albumin, total protein, T3, and GSH and increased the levels of TSH, adiponectin, leptin, ROS, MDA, and T4/T3 ratio compared to those in the control LFD or HFD group. In conclusion, combined exposure to HFD and arsenic induced hypothyroidism via reduction of thyroid hormones and enhancement of plasma TSH and T3 uptake levels concomitant with hypolipidemia, hyperleptinemia, hyperadiponectinemia, induction of oxidative stress, and reduction of GSH levels.

Abstract
Obesity is a main reason of type 2 diabetes and also chronic exposure to arsenic (As) can produce diabetic symptoms. In previous studies, the association between high-fat diet and arsenic in the incidence of diabetes was found, but the role of beta cells activity, liver mitochondrial oxidative stress, and hepatic enzymes (leptin, adiponectin and beta amylase) was unclear. Thus, present study was conducted to evaluate the diabetogenic mechanism of arsenic followed by concomitant administration of high-fat diet (HFD) in male mice. In this experimental study, the mice consumed with HFD or low-fat diet (LFD) while exposed to As 25 or 50 ppm in drinking water for 20 weeks. At the end of experiments, hyperglycemia, insulin resistance variables, lipid profile, hepatic enzymes, liver mitochondrial oxidative stress, islet insulin secretion, liver, and pancreas histopathology were evaluated in all mice by their own methods. Control HFD fed mice showed a significant increase in FBG, OGTT, HOMA-IR, ITT, lipid profile, leptin, β-amylase, liver mitochondrial oxidative stress, hepatic enzymes and decreased FPI, HOMA-β, adiponectin, and islet insulin secretion or content. However, exposure to HFD concomitant with Arsenic revealed an impressive reduction in FBG, FPI, HOMA-IR, HOMA-β, ITT, lipid profile, and islet insulin secretion or content. This exposure enhanced OGTT, leptin, adiponectin, liver mitochondrial oxidative stress, and hepatic enzymes. In conclusion, HFD and arsenic concomitant administration induced impairment of OGTT and islet insulin secretion or content through the mitochondrial oxidative stress.

Abstract
Type 2 diabetes mellitus (T2DM) may occur via oxidative stress. Myricitrin is a plant-derived antioxidant, and its solid lipid nanoparticle (SLN) may be more potent. Hence, the present study was conducted to evaluate the effects of myricitrin SLN on streptozotocin-nicotinamide- (STZ-NA-) induced T2DM of the mouse and hyperglycemic myotube. In this experimental study, cold homogenization method was used to prepare SLN. Then, 120 adult male NMRI mice were divided into 7 groups: control, vehicle, diabetes (received STZ 65 mg/kg 15 min after injected NA 120 mg/kg), diabetes + SLN containing myricitrin 1, 3, and 10 mg/kg, and diabetes + metformin. For in vitro study, myoblast (C2C12) cell line was cultured and divided into 6 groups (n = 3): control, hyperglycemia, hyperglycemia + SLN containing myricitrin 1, 3, and, 10 μM, and hyperglycemia + metformin. After the last nanoparticle treatment, plasma samples, pancreas and muscle tissues, and myotubes were taken for experimental assessments. Diabetes increased lipid peroxidation and reduced antioxidant defense along with the hyperglycemia, insulin resistance, and pancreas apoptosis. Hyperglycemia induced oxidative stress, antioxidant impairment, and cellular apoptosis. Myricitrin SLN improved diabetes and hyperglycemia complications in the in vivo and in vitro studies. Therefore, SLN of myricitrin showed antioxidant, antidiabetic, and antiapoptotic effects in the mouse and myotube cells.

Abstract
Investigations into pharmaceutical intervention of pancreatic and hepatic dysfunction associated with metabolic disturbances have received relatively little attention. The aim of this study was to investigate the protective effects of exendin-4 in mice receiving D-galactose, a reducing sugar that triggers ROS production and inflammatory mediators affecting the pancreas and liver. Exendin-4 is an United States Food and Drug Administration (FDA) approved glucagon-like peptide that increases insulin dependent glycogen synthesis and glucose uptake. Male NMRI mice (20–25 g), 3 months of age, were randomly divided into 6 groups of 12 mice each: control, exendin-4 (1 nmol/kg), exendin-4 (10 nmol/kg), D-galactose, D-galactose + exendin-4 (1 nmol/kg) and D-galactose + exendin-4 (10 nmol/kg). D-galactose (500 mg/kg) was given daily by oral gavage for 6 weeks. During the last 10 days, exendin-4 (1 and 10 nmol/kg) was injected intraperitoneally daily. Glucose, insulin, insulin resistance, lipid profiles, and hepatic enzyme levels significantly increased in the D-galactose group (p < 0.05), along with a significant decrease in superoxide dismutase activity and pancreatic islet insulin secretion (p < 0.05). Exendin-4 decreased D-galactose-induced increases in serum glucose and insulin, insulin resistance, lipid profiles, and hepatic enzymes, and improved pancreatic islet insulin secretion and antioxidant defense status. The results show that exendin-4 can prevent complications in mice with compromised pancreatic and hepatic function. Long term administration of D-galactose in mice may be a useful model to study insulin resistance, metabolic syndrome, and aging.

Abstract
OBJECTIVE Arctium lappa (burdock), (A. lappa) root has hypoglycemic and antioxidative effects, and has been used for treatment of diabetes in tradition medicine. This study was conducted to evaluate the antidiabetic and hypolipidemic properties of A. lappa root extract on nicotinamide-streptozotocin (NA-STZ)-induced type2 diabetes in mice. MATERIALS AND METHODS In this investigation, 70 adult male NMRI mice (30-35g) randomly divided into 7 groups (n=10) as follow: 1-control, 2-type 2 diabetic mice, 3-diabetic mice that received glibenclamide (0.25 mg/kg) as an anti-diabetic drug, 4, 5, 6 and 7- diabetic and normal animals that were pre-treated with 200 and 300 mg/kg A. lappa root extract, respectively, for 28 days. Diabetes has been induced by intraperitoneal injection of NA and STZ. Finally, the blood sample was taken and insulin, glucose, SGOT, SGPT, alkaline phosphatase, leptin and lipid levels was evaluated. RESULTS Induction of diabetes decreased the level of insulin, leptin and high density lipoprotein (HDL) and increased the level of other lipids, glucose, and hepatic enzymes significantly (p<0.05). Administration of both doses of the extract significantly decreased the level of triglyceride, very low density lipoprotein, glucose and alkaline phosphatase in diabetic mice (p<0.05). Insulin levels increased in animals treated with 200 mg/kg (p<0.05) and HDL and leptin levels increased in animals treated with 300 mg/kg of the extract (p<0.01). CONCLUSION The results showed that A. lappa root extract, at specific doses, has an anti-diabetic effect through its hypolipidemic and insulinotropic properties. Hence, this plant extract may be beneficial in the treatment of diabetes.

Abstract
D-galactose induces pancreatic disorder along with aging mouse model. Vitex agnus-castus (VAC) has potential pancreatic protective effect. Hence, this study was designed to evaluate the hypoglycemic and pancreas protective effects of VAC hydroalcoholic extract in D-galactose-induced aging female mice. In the present experimental study, 72 adult female Naval Medical Research Institute (NMRI) mice (weighing 30–35 g) were divided into 6 groups of control, VAC hydroalcoholic extract, D-galactose, D-galactose + VAC hydroalcoholic extract, aged, aged + VAC hydroalcoholic extract. The aged model was prepared by subcutaneous injection of D-galactose for 45 days and, VAC hydroalcoholic extract was gavaged twice a day in the last 7 days. 24 h after the last drug and extract administrations, serum samples and pancreatic tissues were removed to evaluate experimental and histological determinations. Serum glucose level decreased in VAC, D-galactose and, aged-treated groups compared to the control (P < 0.05). Insulin level increased in VAC and decreased in D-galactose and aged VAC-treated mice compared to the control (P < 0.05). Homeostasis model assessment-estimated insulin resistance (HOMA-IR) increased in D-galactose, aging, and VAC hydroalcoholic extract groups (P < 0.05) and, administration of VAC hydroalcoholic extract improved HOMA-IR in D-galactose and aging treated animals. Despite the size of pancreatic islets decreased in aged and D-galactose groups, VAC administration recovered it. Present data showed that VAC hydroalcoholic extract has hypoglycemic and pancreatic protective effects in natural aged and aging model mice.

Abstract
AIM The aim of the present study was to evaluate the different doses of Butyric acid (BA) and Arsenic (As) in liver mitochondria oxidative stress and pancreatic islet insulin secretion of male mouse. BACKGROUND BA is found in many foods and As as a toxic metal is present in drinking water. They can induce oxidative stress in tissues. METHODS In this experimental study, Liver mitochondria were isolated by administration of the different centrifugation method and pancreatic islets were isolated by collagenase method. Mitochondria were incubated by BA (35, 75, 150, 300 μM) and As (20, 50, 100, 200 μM) as the islets were incubated by BA (250, 500, 1000, 1500 μM) and As (50, 100, 200 μM) for 1 hour. At the end of the experiment, mitochondrial viability and membrane potential, ROS, MDA, GSH and islets insulin secretion were measured by their specific methods. RESULTS BA and As administration increased mitochondrial levels of ROS, MDA and decreased GSH and pancreatic islet insulin secretion in a dose dependent manner (p<0.05). The doses of BA 75μM and As 100μM have been revealed the most mitochondria toxic concentrations. Also, the doses of 1000μM for BA and 100μM for As were considered as reducing concentrations for islets insulin secretion. Additionally, co administration of them intensified more these effects. CONCLUSION Alone or in combination administration of BA and As induced oxidative stress in liver mitochondria and decreased insulin secretion of pancreatic islets.

Abstract
Purpose The present study was conducted to evaluate the favorable or harmful effects of betulinic acid (BA) on a diabetic reproductive system. Materials and Methods In this experimental study, 60 male Naval Medical Research Institute mice (20∼25 g) were randomly divided into 6 groups: control, diabetes, diabetes+BA (10, 20, and 40 mg/kg), and diabetes+ metformin (200 mg/kg). A diabetic model was induced by a single dose of streptozotocin (STZ) (65 mg/kg) injection intraperitoneally 15 minutes after an intraperitoneal administration of nicotinamide (NA) (120 mg/kg). BA and metformin were gavaged for 2 weeks after confirmed diabetes induction in the treatment groups. One day after the last treatment, plasma luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels were evaluated. The cauda epididymis and testis were removed to analyze the sperm count and testis histopathology. Results LH levels increased in diabetic (p<0.001) and diabetic BA-treated mice (p=0.009). Plasma levels of testosterone (p< 0.001) and sperm count (p=0.04) decreased in these groups when compared to the control group. Furthermore, administration of 10 mg/kg (p=0.001), 20 mg/kg (p=0.004), or 40 mg/kg (p<0.001) of BA led to a greater reduction in plasma testosterone levels compared to the diabetes group. Seminiferous tubule vacuole numbers increased in diabetic and diabetic BA-treated mice, but testis morphology and FSH level assessment revealed no significant differences between the groups. Conclusions STZ-NA can induce diabetic alterations in the male reproductive system and the administration of BA in diabetic treated mice resulted in a worse outcome.

Abstract
Purpose The purpose of this study was to evaluate the role of exendin-4 on reproductive alteration in a D-galactose-induced aging mouse model. Materials and Methods In this experimental study, 72 male Naval Medical Research Institute mice (20~25 g) were randomly divided into six groups: control, exendin-4 (1 nmol/kg), exendin-4 (10 nmol/kg), D-galactose (500 mg/kg), D-galactose+exendin-4 (1 nmol/kg), and D-galactose+exendin-4 (10 nmol/kg). The aging model animals were gavaged with D-galactose for six weeks, and exendin-4 was injected intraperitoneally in the last 10 days. At the end of treatment serum luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone levels were evaluated and the cauda epididymis and testis were removed to analyze the sperm count and testis morphology. Results The testis weight and volume decreased in the D-galactose group (p<0.01 and p<0.05) respectively. Exendin-4 (1, 10 nmol/kg) increased these parameters in the normal and aging mouse models. Serum LH and FSH levels increased and the sperm count decreased in the D-galactose group (p<0.05). Further, exendin-4 (1 nmol/kg) decreased LH and FSH levels and increased the serum testosterone level and sperm count in both normal and aging animals. Conclusions D-galactose can induce aging alternations in the male reproductive system such as decreased sperm count and increased serum LH and FSH levels through reactive oxygen species over production and reduced antioxidant enzyme activity. Further, co-administration of exendin-4 reduced reproductive complications of D-galactose in an aging mouse model.

Abstract
PURPOSE The purpose of this study was to investigate the effects of the hydro-alcoholic extract of Rhus coriaria seeds on the reproductive system of nicotinamide-streptozotocin-induced type-2 diabetic mice. MATERIALS AND METHODS In this experimental study, 56 male Naval Medical Research Institute mice were randomly divided into seven groups (n=8): control; diabetic mice; diabetic mice administered glibenclamide (0.25 mg/kg); diabetic mice who received the hydro-alcoholic extract of R. coriaria seeds (200 and 400 mg/kg groups); and normal mice who received this extract (200 and 400 mg/kg groups). Diabetes was induced by intraperitoneal administration of streptozotocin (65 mg/kg) 15 minutes after an injection of nicotinamide (120 mg/kg). Then, glibenclamide and the above mentioned extract were administered orally for 28 consecutive days. Twenty-four hours after the last treatment, serum samples, the testes, and the cauda epididymis were removed immediately for hormonal, testis morphology, and sperm parameter assessments. RESULTS Body and testicular weight, sperm count and viability, and serum luteinizing hormone, follicle-stimulating hormone and testosterone levels were significantly lower in the diabetic mice (p<0.05). The diabetic mice treated with 400 mg/kg of the hydro-alcoholic extract of R. coriaria seeds recovered from these reductions (p<0.05). Further, glibenclamide alleviated hormonal and sperm count depletion in diabetes-induced mice (p<0.05). CONCLUSIONS The present results indicated that the hydro-alcoholic extract of R. coriaria seeds has anti-infertility effects in diabetic males.

Abstract
BACKGROUND One of the considerable uses of lettuce (Lactuca sativa) seed in traditional medicine has been to reduce semen, sperm and sexuality. OBJECTIVE The aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis. MATERIALS AND METHODS In this experimental study 24 adult male NMRI mice weighing 20-25gr were purchased. Animals were randomly divided into 4 groups: controls, hydro-alcoholic (200 mg/kg) and aqueous extracts (50, 100mg/kg). The extracts were injected intraperitoneally once a day for 10 consecutive days. 2 weeks after the last injection, the mice were anaesthetized by ether and after laparatomy blood was collected from the heart to determine testosterone by ELISA assay kit. Then testis and cauda epididymis of all animals were removed for analyzing testis morphology and sperm count and viability. RESULTS Testis weight in hydro-alcoholic and aqueous extracts 100 mg/kg (p=0.001) and aqueous extract 50 mg/kg (p=0.008) groups was increased. Sperm viability in hydro-alcoholic (p=0.001) and aqueous extracts 50 (p=0.026), 100 mg/kg (p=0.045) groups was decreased, Also the results showed a significant decrease in sperm count in hydro-alcoholic (p=0.035) and aqueous extracts 50 mg/kg (p=0.006) groups in comparison with control group. Also there was a significant increase in serum level of testosterone in aqueous extract 50 mg/kg group in comparison with control (p=0.002) hydro-alcoholic (p=0.001) and aqueous extracts 100 mg/kg (p=0.003) groups. CONCLUSION Present results demonstrated that hydro-alcoholic and aqueous 50 mg/kg extracts of lettuce seed have antispermatogenic effects, also aqueous extract 50 mg/kg increased serum level of testosterone in mice. Therefore we can suggest that lettuce seed could be a potential contraceptive agent. This article extracted from M.Sc. student research project. (Ali Akbar Oroojan).

Abstract
BACKGROUND Punica granatum Linn. (PG) is native to the Mediterranean region. Its flower exhibited antioxidant activity. The present study attempt to investigate the effect of these extract on uterine contraction and its possible mechanism(s). METHODS Thirty five female Wistar rats (200-300 g) at estrous phases of cycle was examined in this study; pieces of virgin adult rat uterus (1.5 cm) were suspended in an organ bath containing 10 ml of De Jalon solution at 29 °C. Tissue contractility was isometrically recorded. KCl (60 mM), BaCl2 (4 mM) and oxytocin (10 mU/ml) were applied to the tissue in the presence and absence of aqueous and hydroalcoholic extracts of the plant (0.05, 0.1, 0.2, 0.4 and 0.8 mg/ml). Propranolol (1 µM) and naloxane (1 µM) were added in KCl induced contractions. The results were analyzed by ANOVA and p < 0.05 were considered as significant. RESULTS Cumulative concentration of extracts reduced uterine contractions induced by KCl dose-dependently (p < 0.01). Extracts in a dose dependent (p < 0.05) reduced uterine contractions decreased dose-dependently after of addition oxytocin. The extracts added cumulatively to the organ bath reduced contractions but they did not affect uterine contractions induced by BaCl2 except the last dose. Spasmolytic effects of the extracts were not affected by propranolol or naloxane in KCl induced contractions. CONCLUSION Extracts diminished K(+)-induced contraction in uterus, therefore it seems that substances that decrease K(+)-induced contraction can also block voltage dependent calcium channel. The extracts did not have any effect on β-adrenoceptors or potassium channels.

Abstract
BACKGROUND Citrus aurantium is a small citrus tree, with scented white flowers. The C. aurantium is used in Asian herbal medicine primarily to treat digestive problems. OBJECTIVE The goal of this study is to investigate the effect of C. aurantium flower's aqueous extract on uterine contraction in presence of some known uterus stimulants. MATERIALS AND METHODS In experimental study 30 virgin Wistar rats 200-300gr were obtained. After laparatomy, a piece of Uterus was dissected out and mounted in an organ bath (10ml) containing De Jalon (29°C) and contracted by KCl (60mM), oxytocin (10mU/ml) and barium chloride (4mM) then the effect of C. aurantium flower's aqueous extract (1-8 mg/ml) on the uterine contractions was investigated.μμthe role of β-adrenoceptors, opioid receptors were evaluated. RESULTS Cumulative concentrations of the extract (1-8 mg/ml) decreased KCl, oxytocin and barium chloride induced uterine contractions, dose-dependently (p<0.001). C. aurantium flower's aqueous extract was unaffected on incubation the tissue with propranolol and naloxone. CONCLUSION It seems that the extract induced antispasmodic effect mainly via calcium influx blockade. However, neither β-adrenoceptors nor opioid receptors were involved. Since the extract has antispasmodic effect on uterus contraction therefore we can suggest that more study will be necessary to relief dysmenorrheal.
