To determine the relation between iron deficiency and the status of thyroid hormones in iron deficient patients. This case control study was done in the Department of Biochemistry, Bangabandhu Sheikh Mujib Medical University (BSMMU), during July 2006 to the June, 2007. Iron deficiency patient was considered as case a healthy control subject was considered as control. A total of 80 subjects were selected for study from those who were attended in out patient department of the above mentioned hospital were enrolled in this study. The mean (±SD) age of case and control were 33.48±11.03 years and 35.40±12.30 years with the range of 16-60 years and 15-60 years respectively. Male female ratio was 1:1.6 in the whole study subjects. Hemoglobin concentration, serum ferritin concentration were significantly (p<0.05) higher in control group but serum TSH level was significantly (p<0.05) higher in case group, however, serum FT3 was almost similar between case and control groups. In iron deficient patients, serum ferritin had no significant negative correlation (r=-0212; p>0.05) with serum TSH and no correlation with serum FT4 concentrations and serum FT3 concentration which were (r=0.055; p>0.05) and (r=0.147; p>0.05) respectively. In control subjects, serum ferritin revealed that there was significant negative correlation (r=-0.337; p<0.05) serum TSH. However, serum ferritin with serum FT4 concentration and serum ferritin with serum FT3 level showed no statistically significant correlation which were (r=0.283; p>0.05) and (r=0.145; p>0.05) respectively. On the other hand, there were no significant (p>0.05) correlation of hemoglobin concentration and serum ferritin with serum TSH, free T3 and free T4 concentrations both in case and control group. There were no significant (p>0.05) difference among serum TSH, free T3 and free T4 concentrations between male and female in both groups. Serum TSH level was significantly (p<0.05) higher in iron deficient patients and no significant negative correlation, serum ferritin level.

Abstract Horses (n = 20) were divided into 2 groups: oligofructose (OF)-induced equine laminitis group (group OF; n = 11) which received 10 g/kg b.w. of OF dissolved in 4 L water via nasogastric intubation, and control group (NS; n = 9) which received 4 L of saline. Blood was collected at 4 h intervals over 72 h study period and analysed by ELISA, kinetic limulus amoebocyte lysate assay, and glucose-oxidase methods. The level of insulin changed significantly in horses which received OF (P < 0.01); there was a significant negative correlation between the level of adiponectin and insulin over time. The results suggested that insulin may play an important role in the development of OF-induced equine laminitis by altering the level of endothelin-1 and nitric oxide.

Objective: The objective of this research was to evaluate oxidative stress status in children with β-thalassemia major.Methods: Our study was conducted in children with β-thalassemia aged from 5 to 15 years. Investigate the urinary excretion of human 8-oxo-7,8- dihydro-2′-deoxyguanosine, which will be analyzed by enzyme-linked immunosorbent assay. To investigate serum levels of antioxidant enzymes include glutathione s-transferase (GST) and catalase (CAT).Results: We found a significant elevation of the urinary 8-oxo-7,8-dihydro-2′-deoxyguanosine level with p=0.001 compared to control group, a significant reduction of both GST and CAT p=0.05 and 0.03, respectively, compared to control group. There was a significant negative correlation between urinary 8-oxo-7,8-dihydro-2′-deoxyguanisine and CAT level, r=−0.378, p=0.016, hemoglobin - r=−0.610, p=0.001, hematocrit (%) - r=−0.478, p=0.002, while a significant positive correlation between urinary 8-oxo-7,8-dihydro-2′-deoxyguanisine and alanine aminotransferase - r=0.547, p=0.001, and serum ferritin - r=0.391, p=0.013. There was a significant negative correlation between CAT and serum ferritin - r=−0.320, p=0.44.Conclusion: We conclude that the strongly increased urinary excretion 8-oxo-7,8=dihydro-2′-deoxyguanisine indicates elevated lipid peroxidation induced DNA damage in internal organs such as the liver. These highly pro mutagenic lesions may contribute to the increased risk of thalassemia patients to develop hepatocellular carcinoma.

Background: Iron and thyroid hormone metabolism are closely related with each other. Iron plays an important role for both the synthesis as well as metabolism of thyroid hormones acting as a component of many enzymes including thyroid peroxidase (TPO). So, iron deficiency can lead to abnormal functioning of thyroid gland. Ferritin is storage form of iron in our body. Several studies in showed that nutritional iron deficiency can significantly decrease the circulating levels of both T4 and T3 and it can also reduce peripheral conversion of T4 to T3. So, the aim of the study is to find out whether there is any relationship between hypothyroidism and iron metabolism.Methods: This cross-sectional descriptive study was conducted at Deben Mahata Government Medical College and Hospital, Purulia on 50 hypothyroid patients and 50 age and sex matched controls after imposing inclusion and exclusion criterias. Blood samples were collected and estimation of Serum TSH, fT4 and fT3, iron, ferritin and TIBC levels were done. Then the data obtained were analysed by proper statistical methods.Results: Out of 100 subjects 68 were male and rest were female. The mean serum TSH level in study population was significantly higher than that of comparison group. While serum fT3 and fT4 level in study group were lower than the control group and both were statistically significant. In the other hand, the mean serum ferritin and iron levels in cases were lower than that in controls and the mean TIBS was higher in study group and all the differences were statistically significant. There were significant correlation between Serum ferritin and serum iron (positive correlation), Serum ferritin and TSH (negative correlation), Serum TSH and fT4 (negative correlation) but there was no significant relationship between serum TSH and iron.Conclusions: The iron metabolism is disturbed in hypothyroidism reflected by low serum ferritin and iron.

Abstract Background Dyspnea is a frequent symptom among patients with thyroid disorders. However, its actual causative mechanism is not clear. The diaphragm is the main inspiratory muscle and contraction of the diaphragm is essential for breathing, so any disorder that interferes with contractile muscle function can cause diaphragm dysfunction which is associated with dyspnea. The objective of study is to assess the effect of thyroid disorders on diaphragm excursion and thickness. Results Diaphragmatic excursion during tidal, deep, and sniff respiration were significantly decreased in patients with thyroid disorder in comparison to control and significantly decreased in hypothyroid patients (right tidal 1.42 ± 0.29, right deep respiration 5.07 ± 0.72, and sniff 2.15 ± 0.26 cm) than hyperthyroid patients (right tidal 1.61 ± 0.34, right deep respiration 5.63 ± 0.50, and sniff 2.67 ± 0.27 cm) and than the control group (right tidal 2.17 ± 0.27, right deep respiration 6.63 ± 0.33, right sniff 2.89 ± 0.19 cm). Diaphragmatic thickness at end tidal inspiration was significantly decreased in patients with thyroid disorder in comparison to control (p value < 0.05). There was negative correlation between diaphragmatic excursion and duration of disease. Conclusion Diaphragmatic excursion and thickness are affected in hypothyroidism compared to hyperthyroidism and control groups. There is significant negative correlation between diaphragmatic excursion and duration of disease in patients’ group. Respiratory symptoms are more frequent in hypothyroid patients.

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.

Background/Aim. According to currently available data, there is no research dealing with evaluating empathy in adolescents with conduct disorders in our region. The aim of the research was to examine the differences in the severity of cognitive and affective empathy in adolescents with and with no conduct disorder, as well as to examine the relationship between cognitive and affective empathy and the level of externalization in adolescents with conduct disorder. Methods. This research was conducted on 171 adolescents, aged 15 to 18, using the Interpersonal Reactivity Index, Youth Self- Report and a Questionnaire constructed for the purpose of this research. Results. The results showed that adolescents with conduct disorder had significantly lower scores for Perspective Taking (t = 3.255, p = 0.001), Fantasy (t = 2.133, p = 0.034) and Empathic Concern (t = 2.479, p = 0.014) compared to the adolescents in the control group, while the values for Personal Distress (t = 1.818, p = 0.071) were higher compared to the control group, but the difference was not statistically significant. The study showed a statistically significant negative correlation between Perspective Taking and aggression (r = - 0.318, p = 0.003) and a negative correlation between Perspective Taking and the overall level of externalizing problems (r = -0.310, p = 0.004) in the group of adolescents with conduct disorder. Conclusion. This research contributes to better understanding of behavioral disorders in terms of individual factors, especially empathic reactivity. Preventive work with young people who have behavioral problems associated with empathy deficit disorder proved to be an important tool in preventing the development, or at least relieving the symptoms, of this ever more common disorder.

BACKGROUND: The COVID-19 pandemic has created a wide range of sociocultural pressures on nurses. Resilience is defined as one’s ability to adapt to an unpredictable situation and it can be a factor in accepting an undesirable psychosocial situation. OBJECTIVE: The aim of the present study was to examine resilience in nurses in the face of job stress during the COVID-19 pandemic. METHODS: The study was carried out as a case-control study with participation of 400 nurses as the target group (nurses exposed to COVID-19 patients) and the control group (nurses not exposed to COVID-19 patients). To examine resilience and job stress, Conor and Davidson’s questionnaire and OSIPOW questionnaire were used respectively. RESULTS: The mean scores of job stress and resilience were significantly different between the target and control groups (p <  0.05). So that resilience in the target group was less than that in the control group. In addition, job stress in the target group was higher than that of the control group (p <  0.05). There was a significant and negative correlation between resilience and job stress and the correlation was stronger in the target group (p <  0.05). CONCLUSIONS: Given the high job stress score in the participants and its negative correlation with resilience, there is need to provide the health personnel with efficient preventive and treatment approaches, improve and educate the principles of resilience, improve mental health services system, and introduce programs to control some of demographical factors in job stress such as physical activity, and employment status of nurses.

PollutiOn is the intrOduction Of contaminantsʹ intO the natural envirOnment that cause adverseʹ change. Gasoline is a toxic and highly flammable liquid consists of various types of aliphatic hydrocarbons, olefins, benzenes and aromatic hydrocarbons including toluene, xylene and a large number of volatile compounds in addition to tetraethyl lead. Gasoline consists of different types of aliphatic hydrocarbons, aryl compounds and some trace elements. Trace elements are several important roles in human bodies, some are essential for enzymes reactions where they attract and facilitate conversion of substrate molecules to specific end products. Aryl hydrocarbon receptor (AHR) is a receptor involved in the regulation of biological responses to planar aromatic hydrocarbons.       The aim of the present study is to compare the serum AHR level in the fuel station workers (FSW) with the non-workers as a control group. The other aim is to find out a possible correlation between AHR with trace elements.              Sixty male FSW and 30 controls, from ten fuel stations at Al-Najaf City-Iraq, were participated in the present study. The AHR level in serum was measured using ELISA technique. Determine the following metal ions Zn2+, Cu2+, Fe3+, Mg2+, Na+ and K+ level in filling station workers (FSW) and control group were measured spectrophotometrically by using ready for use kits. Serum Pb level was carried out using Atomic absorption spectroscopy.              The results serum concentration of AHR in FSW group revealed a significant increase (p<0.001) as compared with the control group. No significant difference was noticed in AHR as compered in exposure ≥12years with exposure <12years in FWS. Smoking has no significant correlation with other parameters. Correlation study indicated a correlation between AHR and Age. Serum concentration of Cu2+, Zn2+, K+ and Pb in FSW group revealed a significant increase (p<0.001) as compared with the control group. While Fe3+, Na+ and Mg2+ in FSW group revealed a significant decrease (p<0.001) as compared with the control group. Correlation study indicated a significant negative correlation between serum Pb and AHR while other trace elements showed no significant correlation with AHR in FSW group. There is a significant negative correlation between serum Cu2+ with age while there is significant increase correlation between Zn2+, Mg2+ and Pb with age in FWS group.                 Conclusion of study is The role of increase AHR on the health in FSW group, attention to use safety gloves and face mask is recommended for FSW and a long follow-up to the studied group is necessary to explore the    prognosis of increase AHR in FSW.
