مقدمه: با توجه به سهم مهم بیماران بدون عفونت h.pylori (– hp) در اولسر پپتیک و وجود احتمالی فاکتورهای دیگر غیر از h.pylori در ایجاد آن، برای روشن تر شدن ارتباط عفونت h.pylori با علائم بالینی و یافته های اندوسکوپیک و هیستوپاتولوژیک ما دو گروه بیماران + hp و – hp را مورد مقایسه قرار دادیم. روش کار: در این مطالعه مقطعی، 166 بیمار که با شکایات گوارشی مطرح کننده اولسر پپتیک، گاستریت و سایر اختلالات م...
RESULTSdIn the present analysis, 812 subjects participated (84 with Hp 1-1, 335 with Hp 1-2, and 393 with Hp 2-2 genotypes). Average was 72.9 years of age (SD 4.7), and Mini Mental State Exam (MMSE) was 28.0 (SD 1.8). Compared with subjects with Hp 1-2 genotype, Hp 1-1 subjects performed significantly worse in semantic categorization (F = 7.03; P = 0.008) and the overall cognitive score (F = 5....
abstractthe ability of hesperidin (hp) to form complexes with five metals; cobalt, nickel, zinc, calcium and magnesium was investigated. the complexation was studied using u.v spectroscopic titration, in methanol as well as aqueous buffer solutions (physiological conditions). potential complexes were studied by ir and nmr spectroscopy, melting point and their solubility were also evaluated. the...
Polymorphic loci regulating oxidative stress are potential susceptibility genes for diabetic nephropathy (DN). Haptoglobin (Hp) is an antioxidant protein which serves to protect against oxidative stress induced by extracorpuscular hemoglobin. There are two alleles at the Hp locus, 1 and 2. The Hp 1 protein is a superior antioxidant to the Hp 2 protein. The Hp 2 allele has been associated with i...
Aim: This study aimed to analyze helicobacter pylori (Hp) risk factors, which may provide evidence for the prevention and treatment of Hp infection. Methods: 8115 subjects were recruited. Questionnaire surgery was done in 487subjects who received gastroscopy. Results: The incidence of Hp infection was 35.2% in males and 30.3% in females showing significant difference (P<0.05). The mean age was ...
Helicobacter pylori (Hp) is one of the most common bacteria infecting humans. Recently, certain extragastric manifestations, linked to Hp infection, have been widely investigated, suggesting that Hp infection might be a 'systemic' disease. Accumulating, yet limited, evidence points to a potential association between Hp infection and lung cancer risk. Epidemiologic studies have shown that odds r...
BACKGROUND Whether the characteristics and prognosis of gastric cancer (GC) are different in patients with and without Helicobacter pylori (HP) remains controversial. The definitions of HP status in patients with atrophic gastritis but negative tests for HP are heterogeneous. We aimed to assess the impact of HP on the prognosis of GC using different definitions. METHODS From 1998 Nov to 2011 ...
haptoglobin (hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. as an important consequence, haptoglobin-hemoglobin complex (hp-hb) shows considerable antiox...
Frequency of helicobacter pylori among patients with diabetes mellitus : Research Center for Gastroenterology and Liver Disease, Shaheed Beheshti University of Medical Sciences Abstract: Background: It is believed that diabetes mellitus (DM) increase the susceptibility to Helicobacter Pylori (HP) infection, but there is little information about the role of DM in being infected patients wi...
