It is well known that eosinophilia is a key pathogenetic component of toxocariasis. The objective of the present study was to determine if there is an association between peritoneal and blood eosinophil influx, mast cell hyperplasia and leukotriene B(4) (LTB(4)) production after Toxocara canis infection. Oral inoculation of 56-day-old Wistar rats (N = 5-7 per group) with 1000 embryonated eggs c...
Leukotriene (LT) B(4) is an inflammatory mediator that has been implicated in the pathogenesis of various diseases, including inflammatory bowel disease and psoriasis. As the rate-limiting step for LTB(4) production, LTA(4) hydrolase represents an attractive target for therapeutic agents that interfere with LTB(4) production. In the present study we evaluated a chemically novel compound designa...
Macrophages increase in number and are highly activated in chronic obstructive pulmonary disease (COPD). Muscarinic receptor antagonists inhibit acetylcholine-stimulated release of neutrophilic chemoattractants, suggesting that acetylcholine may regulate macrophage responses. Therefore, expression and function of components of the non-neuronal cholinergic system in monocyte-macrophage cells was...
BACKGROUND Angiogenesis and lymphangiogenesis are classical features of granuloma formation in pulmonary tuberculosis (PTB). In addition, the angiogenic factor--VEGF-A is a known biomarker for PTB. AIMS/METHODOLOGY To examine the association of circulating angiogenic factors with PTB, we examined the systemic levels of VEGF-A, VEGF-C, VEGF-D, VEGF-R1, VEGF-R2 and VEGF-R3in individuals with PT...
BACKGROUND The association of antimicrobial peptides (AMPs) with tuberculosis-diabetes comorbidity (PTB-DM) is not well understood. METHODS To study the association of AMPs with PTB-DM, we examined the systemic levels of cathelicidin (LL37), human beta defensin- 2 (HBD2), human neutrophil peptides 1-3, (HNP1-3) and granulysin in individuals with either PTB-DM, PTB, latent TB (LTB) or no TB in...
Many of the features of bronchial disease are believed to be caused by damage to the airways by elastase released by recruited neutrophils. There have been few studies of the mechanisms involved and the interrelationships between components of the inflammatory process. We studied secretions from patients with chronic bronchitis in the stable state. We assessed the presence of neutrophils by mea...
بیماری اسهال از معضلات مهم بهداشت جهانی برای جوامع انسانی و سیستم های پرورش صنعتی دام محسوب می شود. از مجموعه عوامل بیماری زا، باکتری های روده ای نقش مهمی در ایجاد این بیماری ها دارند. از میان سموم تولید شده توسط این باکتری ها، سم حساس به حرارت (lt) باکتری اشریشیا کلی مولد سم روده ای (etec)، سم کلرا (ctx) باکتری ویبریو کلرا و سم شیگا باکتری اشریشیا کلی خونریزی دهنده روده ای (ehec) که به ترتیب ع...
Abstract Based on the geometry of codimension-2 surface in general spherically symmetric spacetime, we give a quasi-local definition photon sphere as well surface. This new is generalization one provided by Claudel, Virbhadra, and Ellis but without referencing any umbilical hypersurface spacetime. The effectively excludes spacetime gravity. application to Lemaître–Tolman–Bondi (LTB) model gravi...
