we have reviewed the medical records of 40 patients with disseminated (bacille calmette-guerin) bcg from 1996 to 1999 in the immunology department of the children hospital, medical center, tehran university. these patients are divided in to 3 groups: 1. patients who had disseminated (bacille calmette-guerin) bcg after vaccination and their diagnosis was chronic granulomatous disease. 2. patient...

Leukocyte adhesion defect (LAD) is a rare, autosomal recessive primary immunodeficiency disorder of phagocytes, in which there is defective aggregation at the site of infection due to the absence of surface integrins. Diagnosis is based primarily on flowcytometric analysis of neutrophils for the surface expression of CD11, CD18 and CD15s. We describe here a case of a 7-months-old boy who presen...

Diabetes mellitus (DM) is a major risk factor for tuberculosis (TB) but the defect in protective immunity responsible for this has not been defined. We previously reported that streptozotocin-induced DM impaired TB defense in mice, resulting in higher pulmonary bacterial burden, more extensive inflammation, and higher expression of several proinflammatory cytokines known to play a protective ro...

The results of a study the wound healing activity composition based on hydrogel polyhexamethylene guanidine hydrochloride and Bergenia crassifolia extract, under conditions modeling thermal burns in laboratory animals (rats), are presented. It was found that affects change summary antioxidant leukocyte towards normalization these indicators. Morphological analysis slices showed that, influence ...

BACKGROUND AND PURPOSE The dynamics of leukocyte infiltration in human cerebral ischemia were studied using technetium-99m hexamethylpropyleneamine oxime (99mTc HMPAO)-labeled leukocyte brain single-photon emission computed tomography (SPECT). METHODS Twenty-two patients diagnosed as having hemispheric ischemic stroke were examined with 99mTc HMPAO brain SPECT for cerebral blood flow study an...

Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency disorder with autosomal recessive inheritance which is characterized by presence of a defect of phagocytic function resulting from a lack of leukocyte cell surface expression of b2 integrin molecules (CD11 and CD18) that are essential for chemotaxis. The classic symptoms of the disease are failure of separation of the umbili...

Delays in leukocyte localization likely contribute to diminished host defense in neonates. Understanding the processes that may be affected has been hampered by the lack of suitable developmental models. Using intravital microscopy, we directly examine leukocyte recruitment in a rabbit pup model. In response to intraperitoneal interleukin (IL)-1beta, there were one-third as many leukocytes that...
