To evaluate the association of HLA types with Turkish patients with Graves' disease, HLA typing, clinical findings, and thyroid antibodies were correlated. The HLA types, clinical findings (ophthalmopathy and age at onset), and thyroid stimulating hormone (TSH) receptor (TRAb) and antithyroid microsomal antibodies (MAb) were analyzed. Seventy Turkish patients with Graves' disease and 306 control subjects were assessed. Serological HLA typing was performed in HLA A, B, C, DR, and DQ loci. There was a significantly increased prevalence of HLA B8, B49, DR3, DR4, and DR10 in Graves' disease. The association of Graves' disease with HLA DR3 was found to be less strong than previously described. The HLA DR4 antigen may contribute to the predisposition of Graves' disease in Turkey. The results suggest that HLA B7, B13, DR7, DQw2, and DQw3 may confer a protective effect for Graves' disease in Turkey. Patients carrying HLA B12, B18, and B44 haplotypes had a tendency to develop the disease at a later age. The difference from the other studies may be the result of the selection of the controls; in part, of the variability in serological typing reagents; and, also, of the rather weak HLA associations with the disease.This study was presented in part at the Annual Meeting of the National Endocrinology and Diabetes Association, Bursa, Turkey, May 25–28, 1992. 相似文献

Acylglucuronides formed from carboxylic acids by UDP-glucuronosyltransferases (UGTs) are electrophilic metabolites able to covalently bind proteins. In this study, we demonstrate the reactivity of the acylglucuronide from the nonsteroidal anti-inflammatory drug, ketoprofen, toward human and rat liver UGTs. Ketoprofen acylglucuronide irreversibly inhibited the glucuronidation of 1-naphthol and 2-naphthol catalyzed by human liver microsomes or by the recombinant rat liver isoform, UGT2B1, which is the main isoform involved in the glucuronidation of the drug. A decrease of about 35% in the glucuronidation of 2-naphthol was observed when ketoprofen acylglucuronide was produced in situ in cultured V79 cells expressing UGT2B1. Inhibition was always associated with the formation of microsomal protein-ketoprofen adducts. The presence of these covalent adducts within the endoplasmic reticulum of cells expressing UGT2B1 was demonstrated following addition of ketoprofen to culture medium by immunofluorescence microscopy with antiketoprofen antibodies. Immunoblots of liver microsomes incubated with ketoprofen acylglucuronide and probed with antiketoprofen antibodies revealed the presence of several protein adducts; among those was a major immunoreactive protein at 56 kDa, in the range of the apparent molecular mass of UGTs. The adduct formation partially prevented the photoincorporation of the UDP-glucuronic acid (UDP-GlcUA) analog, [beta-32P]5N3UDP-GlcUA, on the UGTs, suggesting that ketoprofen glucuronide covalently reacted with the UDP-GlcUA binding domain. Finally, UGT purification from rat liver microsomes incubated with ketoprofen glucuronide led to the isolation of UGT adducts recognized by both anti-UGT and antiketoprofen antibodies, providing strong evidence that UGTs are targets of this metabolite. 相似文献

【In Press】 Protective effect of pomegranate juice on retinal oxidative stress in streptozotocin-induced diabetic rats 下载免费PDF全文
AIM: To investigate the effect of pomegranate juice (PJ) intake on overall oxidation status in retinas of diabetic rats.
METHODS: Twenty-seven rats were divided into four groups as control (CO), diabetic (DM), control treated with PC (CO-PJ), and diabetic treated with PJ (DM-PJ).The retina tissues were used to determine 8-Hydroxy-2’-deoxyguanosine (8OHdG), malondialdehyde (MDA), reduced glutathione (GSH) levels, and the enzyme activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px).
RESULTS: The levels of 8OHdG and MDA were significantly increased in the retina of DM group compared to CO group (p=0.001, p<0.001 respectively). Both 8OHdG and MDA levels were decreased in PJ-DM group compared to DM group (p=0.004, p<0.001 respectively). The activities of antioxidant enzymes GSH, SOD, and GDH-Px were significantly decreased in the retina of DM group compared to CO group (p≤0.01). GSH and GSH-Px activities were higher in PJ-DM group compared with DM group (p=0.010, p=0.042, respectively) but SOD activity was not statistically different (p=0.938).
CONCLUSION: PJ intake was found to be effective in decreasing oxidative end products, and in increasing the activities of antioxidant enzymes in diabetic retinas of rats, which suggests it may be effective against oxidative stress in diabetic retinas. 相似文献

Convulsions are one of the frequently seen problems for a neurologist in the daily routine. It is difficult to distinguish the seizure from pseudo-seizure because of lack of conclusive tests. The aim of this study is to investigate the relationship between seizure types and seizure periods by studying IMA serum levels in children having seizure. Two groups were included (patients and control) in our study. The patient group consisted of the children admitted to Pediatric Emergency Care during January 2008–January 2010 with seizure and the control group consisted of healthy children. Serum Ischemia modified albumin (IMA) level in the group having seizures was 99.7 and 83.2 U/ml in the control group. In the comparison of the patient and control groups, significant differences were found between their IMA values (p = 0.000). There was a significant difference between IMA values of the group having generalized tonic–clonic seizures and those of the control group (p = 0.001). In comparison of the IMA values of the group having febrile convulsions and those of the control group, a significant difference was determined (p = 0.011). It has been shown that if the seizure was prolonged over 5 min, IMA level increased, and there was a significant difference between the groups experiencing over 5 min of seizures and the groups experiencing less than 5 min of seizures (p = 0.001). An increase in IMA levels in febrile convulsion supports the hypoxia development in the brain during the seizure. Serum IMA levels increased with the elongation of the seizure period and may be an indicator for status epilepticus. 相似文献

OBJECTIVE: To investigate the effects of growth hormone (GH) deficiency on serum lipid and leptin concentrations in hypopituitary patients taking conventional replacement therapy and to determine the relations between leptin and gender and anthropometric and metabolic variables. SUBJECTS: Twenty-one GH deficient adult hypopituitary patients (15 women, six men) and 21 (14 women, seven men) age, sex and body mass index (BMI) matched healthy controls. MEASUREMENTS: After an overnight fast, anthropometric parameters were measured and body composition was determined by a bioelectrical impedance analyser. Venous blood samples were obtained for the measurements of glucose, total cholesterol, high density lipoprotein (HDL) cholesterol, triglyceride, intact insulin, insulin-like growth factor 1 (IGF-1) and leptin concentrations. Serum leptin and hormones were analysed by radioimmunoassay. RESULTS: Hypopituitary patients with GH deficiency showed significantly higher triglyceride, total and low density lipoprotein (LDL) cholesterol and lower HDL cholesterol concentrations on conventional replacement therapy. The unfavourable lipid profile was particularly evident in women. Significantly higher leptin concentrations were found in patients compared with healthy controls with similar body fat content (23. 5+/-11.8 ng/ml vs 11.7+/-6.9 ng/ml, P=0.01). This difference remained significant even when leptin values were expressed in relation to fat mass percentage (0.79+/-0.40 vs. 0.42+/-0.17 ng/ml%, P<0.05) and fat mass kg (1.32+/-0.81 vs 0.66+/-0.30 ng/ml kg, P<0. 05). Significant positive correlations were observed between leptin concentrations and body fat percentage and age in the control group. In patients the sole significant relation between leptin and study parameters was the positive correlation observed between leptin and total cholesterol concentrations. Serum leptin concentrations were significantly higher in women than men in the control group, but not in the patients. No significant gender difference was observed when leptin concentrations were expressed in relation to fat mass (percentage and kg). CONCLUSION: Growth hormone deficient hypopituitary patients (particularly women) on conventional replacement therapy have a more atherogenic lipid profile. Leptin concentrations are increased in GH deficient adults even after adjustment for percentage body fat and body fat mass (kg). Although the nature of our data does not allow us to draw any conclusions on the mechanism(s) of increased leptin concentrations in GH deficiency, decreased central sensitivity to leptin and increased leptin production from per unit fat mass, or alterations in leptin clearance, might be operative. 相似文献

Carpal tunnel syndrome (CTS) is one of the most frequent extra-articular manifestations of rheumatoid arthritis (RA). High frequency ultrasonography (US) is a sensitive and specific method in diagnosis of CTS. This study is aimed to: firstly assess diameter frequency of CTS in RA with US and compare with a control group; secondly, investigate relationship of CTS with disease activity. One hundred consecutive RA patients (women/men: 78/22) fulfilling ACR 1987 RA criteria and 45 healthy controls (women/control: 34/11) were enrolled into study. Disease activity parameters, RA and CTS patient global assessment and health assessment questionnaire (HAQ-DI) were recorded. Both patient and control group were questioned about secondary causes of CTS, and Katz hand diagram, Boston CTS questionnaire and Phalen ve Tinel tests were applied once for each hand. Wrist joint and carpal tunnel were assessed with US grey scale and power Doppler US, then cross-sectional area of median nerve (CSA) was calculated. Patients with median nerve CSA between 10.0 and 13.0 mm(2) were evaluated with electromyography (EMG). CTS was diagnosed if CSA of median nerve >13.0 mm(2) or CTS was shown with NCS. Although there was no difference between RA patients and controls in age, sex, history of DM (+) and goitre, CTS was more frequent in RA group (respectively, 17.0% vs. 4.4%, P = 0.038). In RA group with CTS, age, history of DM, disease duration, HAQ-DI score, CTS patient global score, Boston symptom severity and functional status scores were elevated compared to without CTS [respectively, 57 (36-73) vs. 50 (24-76), P = 0.041; 35.3% vs. 6.0%, P < 0.001; 108 (12-396) months vs. 72 (6-360) months, P = 0.036; 1.93 (0.75-2.87) vs. 1.125 (0-2.75), P = 0.013; 52 (1-97) vs. 25 (0-91), P = 0.001; 2.81 (1.18-4.17) vs. 2.0 (1.0-4.01), P = 0.01; 3.37 (1.37-5.0) vs. 2.25 (1.0-5.0), P = 0.008]. No difference was found between CTS (+) and (-) RA patients in acute phase reactants, disease activity and US findings (P > 0.05). Sensitivity of Katz hand diagram was higher than Tinel and Phalen tests (respectively, 100, 60.0, 66.7%). Boston symptom and functional scores of RA patients with CTS diagnosed by EMG were increased than patients CTS (-) by EMG [respectively, 3.05 (1.90-4.27) vs. 1.55 (1.0-2.90), P = 0.002; 3.25 (1.73-3.82) vs. 1.12 (1.0-2.10), P = 0.008]. CTS frequency in RA was found higher than normal population, especially in patients with additional risk factors of CTS. There was no relationship between CTS and disease activity. CTS group had long disease duration and worse functional status. CTS could be a result of the chronic course in RA. In patient with CSA between 10 and 13 mm(2), Boston CTS questionnaire might give additional idea about CTS. 相似文献
