Abstract Stress can be a reason for some physiological and biological disorders in the body. The antioxidative defense system is necessary for the maintenance of redox homeostasis in the organisms. Alkaline water (AW) is in the focus of the scientific interest due to its antioxidative effect. The treatment with AW and sodium ascorbate (SA) is expected to have potential preventive effect on the organism to hyperthermic stress. The aim of this study was to investigate the effect of AW and SA on glucose and cortisol levels during acute hyperthermic stress, in white female Wistar laboratory rats. The rats were divided into three groups, each having 10 subjects. They were exposed in hyperthermic conditions (41˚C) for 80 min, in 21 consecutive days in order to induce oxidative stress. The first group received drinkable water (control group), the second AW, and the third, AW and SA. Plasma glucose levels were determined by colorimetric method. Cortisol level was measured by the enzyme-linked immunosorbent assay method (ELISA). The means were compared using the Tukey test. Differences were considered significant at a level of p<0.05. Our results showed that levels of glucose and cortisol were significantly higher in the group treated with AW on the 21st day after treatment (p<0.0001), but not on the 7th and 14th day as compared to the control group. Also, co-treatment of animals with AW and SA had significantly increased the levels of glucose and cortisol on the 21st day after treatment, indicating a synergistic effect. In conclusion, the individual action of AW or in synergism with SA caused a high protective effect on oxidative damage in white Wistar laboratory rats.

Abstract Background The aim of this study was to investigate the effect of 12 weeks of aerobic training, 4 weeks of detraining and use gonadotropin-releasing hormone agonist (GnRHa) on serum C-reactive protein (CRP) and cortisol levels in girls with central precocious puberty (CPP). Methods Forty-five girls (aged 6–8 years) with precocious puberty were randomly divided into three groups (medication, training and medicine + training groups). Fifteen healthy girls (without precocious puberty) were also included as the control group. Serum CRP and cortisol levels were measured at baseline by the enzyme-linked immunosorbent assay (ELISA) technique. Then, the experimental groups performed an aerobic training program for 3 days/week 20–75 min per day at 45–75% maximum heart rate for 12 weeks. The medication groups also received GnRHa during the study, once a month (1 mL every 4 weeks) by intramuscular injection. Serum CRP and cortisol levels were measured again 48 h after the last training session and also after 4 weeks of detraining. Results Analysis of variance (ANOVA) with repeated measures showed a significant decrease in CRP (p = 0.02) and cortisol levels (p = 0.01) in the training group and the medicine + training group. Detraining led to return of CRP and cortisol levels to the pre-training levels (p = 0.001). No significant difference in serum CRP (p = 0.43) and cortisol levels (p = 0.06) was observed in the medication group. Further, no significant difference was observed between groups in CRP and cortisol. Conclusions Long-term regular moderate training decreases inflammation indices, and detraining eliminates the benefits of training in girls with precocious puberty.

ABSTRACT Objectives: The present study was undertaken to evaluate salivary cortisol levels in children of smokers and nonsmokers and thereby establishing the relationship between cortisol levels in response to anxiety in children based on their father's habit of smoking. Materials and Methods: The study population aged between 8 and 10 years includes two groups. Group 1 is comprised 20 children of cigarette smokers and Group 2 is comprised 20 children of nonsmokers. The passive drooling technique was used to collect unstimulated saliva from the children using a sterile container. Salivary cortisol levels were evaluated using Enzyme-linked Immunosorbent Assay method. The obtained data were subjected to statistical analysis using SPSS software and paired t-test. Results: Higher mean salivary cortisol levels were found in children of smokers compared to children of nonsmokers and the difference between them was significant statistically (P < 0.05). Higher salivary cortisol levels were found in females compared to males and the result was significant statistically (P < 0.05). Conclusion: This study has proved that the smoking habit of the father has a negative influence on the anxiety levels of their children.

Background: Pre-eclampsia(PE) is  the  most  frequently encountered  medical  complication  during  pregnancy. In developing countries PE   is a principal cause of maternal mortality. A disturbance  in  the  angiogenic/antiangiogenic  factors  and  in  the  hypoxia/placental re-oxygenation  process,  seems  to  activate a maternal  endothelial  dysfunction.Aims and Objective: To estimate Vascular Endothelial Growth Factor ( VEGF )  level  in the cord blood of healthy and Preeclamptic ( PEc ) pregnant women and to associate this with Preeclamptic pregnancy.Material and Methods: A case-control study ofUmbilical cord serum VEGF levels from women with uncomplicated pregnancies (control group, n=60) and pregnancies complicated by Pre-eclampsia (n=40). VEGF in the cord serum was estimated by SANDWICH Enzyme Linked Immunosorbent Assay method by using ELISA Kit and then compared between the two groups.Results: The mean VEGF concentrations in the women who had pre-eclampsia  (578.62±468.3)  were lower than in the control group( 625.75±533.1) , but the difference was not statistically significant ( p= 0.8548).  Conclusion VEGF plays a key role in the instability between endothelial dysfunction and angiogenesis that occurs during Preeclampsia.  VEGF levels might be a useful tool for the early diagnosis of Pre-eclampsia.Asian Journal of Medical Sciences Vol.8(1) 2017 21-25

Introduction. Given the significant prevalence of lead in the environment, research in this area has significant social and economic importance. Lead compounds are characterized by high toxicity and increased ability to cumulate in ecosystems, humans, and animals. Lead enters the human body with food, drinking water, atmospheric air, and smoking. Lead causes pathological changes in the nervous system, blood-forming organs, kidneys, etc. Materials and methods. The experiments were carried out on four groups of white female rats, each included seven animals, weighing 150-200 g. The first group of animals was a control. The second group consumed dechlorinated water from the city water supply, followed by lead acetate. The animals from the third and fourth groups drank the same water with sodium stearate and potassium stearate content in a dose of 1/250 LD50. After the 40th-day of the use of these waters, the animals were orally administered lead acetate at a dose of 7 mg/kg. The levels of lipid peroxidation biomarkers were studied by studying the content of diene conjugates (DC) and malondialdehyde (MDA) in blood serum, liver, and kidney homogenates. Results. The administration of 1/2 acetate LD50 to lead in experimental rats drinking water with stearates was accompanied by a significant increase in the DCs concentration and (MDA) in animals. Higher concentrations of LPO products were observed in the group of animals that consumed water from potassium stearate. Conclusions. 1. With the oral administration of lead acetate against the background of drinking water containing stearates at a dose of 1/250 LD50, an increase in lipid peroxidation indices was noted compared with the control group. 2. Higher concentrations of LPO products were observed in the group of animals consuming water from potassium stearate.

Background In some sedimentary environments, such as coastal intertidal and subtidal mudflats, sulfide levels can reach millimolar concentrations (2–5 mM) and can be toxic to marine species. Interestingly, some organisms have evolved biochemical strategies to overcome and tolerate high sulfide conditions, such as the echiuran worm, Urechis unicinctus. Mitochondrial sulfide oxidation is important for detoxification, in which sulfur dioxygenase (SDO) plays an indispensable role. Meanwhile, the body wall of the surface of the worm is in direct contact with sulfide. In our study, we chose the body wall to explore the SDO response to sulfide. Methods Two sulfide treatment groups (50 µM and 150 µM) and a control group (natural seawater) were used. The worms, U. unicinctus, were collected from the intertidal flat of Yantai, China, and temporarily reared in aerated seawater for three days without feeding. Finally, sixty worms with similar length and mass were evenly assigned to the three groups. The worms were sampled at 0, 6, 24, 48 and 72 h after initiation of sulfide exposure. The body walls were excised, frozen in liquid nitrogen and stored at −80 °C for RNA and protein extraction. Real-time quantitative RT-PCR, enzyme-linked immunosorbent assay and specific activity detection were used to explore the SDO response to sulfide in the body wall. Results The body wall of U. unicinctus consists of a rugal epidermis, connective tissue, outer circular muscle and middle longitudinal muscle. SDO protein is mainly located in the epidermis. When exposed to 50 µM sulfide, SDO mRNA and protein contents almost remained stable, but SDO activity increased significantly after 6 h (P < 0.05). However, in the 150 µM sulfide treatment group, SDO mRNA and protein contents and activity all increased with sulfide exposure time; significant increases all began to occur at 48 h (P < 0.05). Discussion All the results indicated that SDO activity can be enhanced by sulfide in two regulation mechanisms: allosteric regulation, for low concentrations, and transcription regulation, which is activated with an increase in sulfide concentration.

Diabetes mellitus type 2 [DMT2] is a disturbance of metabolism and complex diseases influenced by environmental, genetic agents, and linked with inflammation, happens when the pancreas either does not use the insulin as it should or the body does not make enough insulin, lead to insulin resistance [IR] alongside with gradual loss of ß-cell secretory ability. The aim of this study was to investigate the role of soluble L-selectin (sL-selectin) in diabetes mellitus type 2 patients in Iraqi Arabs patient. Study includes seventy six Iraqi Arabs patients (male and female) having newly diagnosed type 2 diabetes mellitus (T2DM), with Fifty three Iraqi Arabs healthy subjects matched in age, sex and ethnic group. Patients and healthy subjects were genotyped, by PCR-RFLP analysis, and mesure serum level of L-selectin by enzyme-linked immunosorbent assay (sandwich ELISA) test include 65 patients and 23 controls. The statistical analysis of serum level of sL-selectin in study groups showed that the mean of sL-selectin level high significantly increased in patients group (10.708±1.1007) compared to control group (7.055±0.767) respectively. Thus, our results suggest soluble L-selectin play a role in the development of DMT2 in Iraqi Arabs patients. Present results showed that genotype PS associated with increase the susceptibility of DMT2.

The aim of this study was to investigate the level of serum cytokines in different periods of pregnancy associated with anemia. 85 pregnant patients with anemia were examined. 46 of them were in their first pregnancy (1st group), and 39 (2nd group) patients were in their second or further pregnancy period. The comparison group consisted of 19 pregnant women without anemia. The level of hemoglobin and serum iron were determined by using colorimetric method, as well as the level of cytokines IL-2, IL-6, IL-8 and IL-10 were determined using an enzyme-linked immunosorbent assay method. The results showed a significant decrease in hemoglobin and serum iron level in the blood of pregnant women with anemia, significant increase in proinflammatory cytokines, such as IL-2 and IL-8, and a significant decrease in IL-10 compared with pregnant women without anemia were also detected. The most pronounced changes in the cytokine profile were observed in the third trimester and during second or futher pregnancy, which is caused by the progression of anemia.

Objective Adropin, a newly identified regulatory protein encoded by Enho gene, is correlated with insulin sensitivity and diabetes. The aim of this study is to determine whether serum and vitreous adropin concentrations are correlated with the presence of diabetic retinopathy. Methods A population of 165 patients with type 2 diabetes mellitus (52 without diabetic retinopathy, 69 with non-proliferative diabetic retinopathy and 44 patients with proliferative diabetic retinopathy) was enrolled in this study. The control group enrolled 68 healthy subjects who had underwent vitrectomy for retinal detachment. Serum and vitreous adropin concentrations were examined using enzyme-linked immunosorbent assay method. Results Control subjects had significantly higher serum and vitreous adropin concentrations compared with diabetic patients. Serum and vitreous adropin concentrations in proliferative diabetic retinopathy patients were significantly reduced compared with those in non-proliferative diabetic retinopathy patients and type 2 diabetes mellitus patients without diabetic retinopathy. In addition, there were lower serum and vitreous adropin concentrations in non-proliferative diabetic retinopathy patients compared with type 2 diabetes mellitus patients without diabetic retinopathy. Logistic regression analysis revealed that serum and vitreous adropin were associated with a decreased risk of type 2 diabetes mellitus and diabetic retinopathy. Conclusion Serum and vitreous adropin concentrations are negatively associated with the presence of diabetic retinopathy.

Objective. Rosella is a safe medicinal herb used by people in Indonesia. They believe that rosella is effective in controlling metabolic syndrome, working with antihypertension, antidiabetic, antidyslipidemia and antiobesity effects. The purpose of this study was to determine the effect of rosella in controlling metabolic syndrome through the secretion of blood nitric oxide (NO) and the cortisol pathway. Methods. This study was a quasiexperimental, pretest-posttest with control group design. The total subjects were 18 people, women, and the elderly. Subjects were selected randomly into 2 groups: control group (n = 8) and treatment group (n = 8). The treatment was rosella tea, a dose of 2 grams, duration 2 times a day, given in the morning (08.00–8.30 a.m.) and evening (06.30–7.00 p.m.) after meals for 21 days. Examination of NO and cortisol levels was carried out using the enzyme-linked immunosorbent assay (ELISA) method. Results. There was a significant decrease in bodyweight (BW) (p=0.021), systolic blood pressure (SBP) (p=0.001), diastolic blood pressure (DBP) (p=0.049), glucose preprandial (FPG) (p=0.014), total cholesterol (CT) (p=0.001), triglycerides (TGs) (p=0.014), high-density lipoprotein (HDL) (p=0.001), and low-density lipoprotein (LDL) (p=0.010) after consuming rosella. NO levels were significantly increased (p=0.012), whereas cortisol levels decreased significantly (p=0.008) after therapy with rosella tea in elderly women. Conclusion. Rosella has shown evidence to control and lower blood pressure, blood glucose, lipid profile, and cortisol in the elderly with metabolic syndrome. Rosella is a traditional medicine that has the potential to be developed as a therapy for metabolic syndrome patients.
