introduction mild intermittent asthma is common in children and viral infections are responsible for the majority of exacerbations. as leukotrienes are potent inflammatory mediators, some studies have shown that montelukast, a leukotriene receptor antagonist, may be effective on reduction of asthma symptom. to determine whether a short course of montelukast in asthmatic children with common col...

the population response of heliothis armigera larvae to nuclear polyhedrosis virus (npv) was investigated. the virus was introduced by permitting the larvae to feed on lettuce leaves. median lethal doses (ld50) were determined. the estimated ld50 values for the first, second, third, early, and late fourth larval instars were 5, 141, 1226, 5168 and 24553 polyhedra per larva respectively. in ...

introduction:blood-borne infectious agents are one of the main anxieties of blood transfusion organization in all countries. according to who, the blood healthy and blood safety is included ensuring and monitoring of quality and efficiency for all patients requiring blood transfusion. we at the current study intend that survey prevalence hiv ab, hcv ab, hbs ag among blood donors refer to the bl...

Background: The most common sexually transmitted diseases and the economic and social health problem throughout the world. However, vaccine coverage and antibiotic therapy and the development of programs to prevent and control major causes of acute and chronic diseases, pregnancy complications and infertility remains.

reye's syndrome is defined as fatty liver degeneration and acute encephalopathy following diffused abnormal mitochondrial activity. we reported a two year old girl admitted with lethargy and meningismus despite no evidence of blood sugar decrease, history of previous viral disease or drug use, complete tests showed reye syndrome as the final diagnosis. conservative protocols and treatment inclu...

background : trichomonas vaginalis is a pathogenic protozoon and may be contaminated with dsrna virus called trichomonas vaginalis virus (tvv). the viral infection is an important factor for its patho-genesis and sensitivity to metronidazole. the presence of tvv is associated with qualitative and quantitative expression of cysteine proteinases and surface immunogenic; p270. the purpose of this ...

host genetic factors play a central role in determining the clinical phenotype of human diseases. association between two polymorphic loci in human genome, human leukocyte antigen (hla) and killer cell immunoglobulin-like receptors (kirs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. hence, defining the influence of genetic di...

Background: Groundnut bud necrosis virus (GBNV) (Tospovirus genus, Bunyaviridae family) infects the major crops of solanaceae, leguminosae and cucurbitaceae in India. Temperature is an important factor which influences the plant growth and development under diseased conditions.Objective: In the present study, we evaluated the effect of four different temp...
