water deficit is one of the most common constraints to crop productivity in the world and iran. in order to study effect of drought stress on morphologic traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based of complete randomized block design with three replication under f.c. irrigation and drought stress in khorasan razavi agricultural research and natu...

Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...

BACKGROUND Disease severity in Mycoplasma pneumoniae (MP) infection could potentially be related to bacterial factors such as MP genotype (MP1 or MP2; distinguished by different adhesions proteins) or bacterial load in airway secretions. We have compared these parameters in patients who were hospitalized for MP pneumonia, with outpatients with mild MP disease. METHODS MP bacterial load was me...

To improve the conventional cold water immersion test for assessing peripheral circulatory function, the immersed area of the hand was changed in this study. Twenty-seven healthy medical students with a mean age of 24 years participated in the study. The cold water immersion tests were carried out using two methods (in 5 degree C water for 1 min), in which the immersed area was up to the metaca...

methylprednisolone (mp) has been widely used as a standard therapeutic agent for the treatment of spinal cord injury (sci). because of its controversial useful effects, the combination of mp and other pharmacological agents to enhance neuroprotective effects is desirable. magnesium sulfate (mgso4) has been shown to have neuroprotective and antihyperalgesic effects. in the present study, we soug...

BACKGROUND Debate exists regarding to whether thiopurine therapy is as effective in ulcerative colitis (UC) as it is in Crohn's disease. AIM To review systematically the efficacy of azathioprine (AZA) and mercaptopurine (MP) in UC, and to conduct a meta-analysis of randomized clinical trials evaluating the efficacy of AZA/MP for the induction or maintenance of UC clinical remission. METHODS...

PURPOSE Mycoplasma pneumoniae (MP) infection is a major cause of respiratory infection in school-aged children. Extrapulmonary manifestations of MP infection are common, but liver involvement has been rarely reported. The aim of this study was to determine the clinical characteristics of MP-associated hepatitis. METHODS This prospective study included 1,044 pediatric patients with MP infectio...

We assessed the bronchodilating effect of glycopyrrolate (GP) and compared it with that of metaproterenol (MP), alone and in combination (GP+MP), in patients with chronic obstructive pulmonary disease (COPD). In a double-blind study, 11 patients (aged (mean +/- SD) 69 +/- 6 yrs; forced expiratory volume in one second (FEV1) 1.2 +/- 0.4 L) with stable COPD inhaled nebulized GP 1.0 mg, MP 15 mg, ...
