BACKGROUND Because many Aboriginal Canadians had severe cases of pandemic (H1N1) 2009 influenza, they were given priority access to vaccine. However, it was not known if the single recommended dose would adequately protect people at high risk, prompting our study to assess responses to the vaccine among Aboriginal Canadians. METHODS We enrolled First Nations and Métis adults aged 20-59 years ...

Lupus pneumonitis carries high mortality and is a rare manifestation of systemic lupus erythematosus (SLE). However, it is difficult to diagnose and is often mistaken as pneumonia, alveolar haemorrhage, or organizing pneumonia. Previous studies demonstrated that serum anti-Ro antibodies are elevated more frequently in SLE patients with pneumonitis than in those without. We report a 21-year-old ...

Anticomplement Immunofluorescence was used for antibody titration against varicellazoster virus (VZV) in 43 patients with peripheral facial palsy. Nine of 31 patients (29%) with Bell's palsy and eight of 12 patients (75%) with Ramsey-Hunt syndrome had anticomplement immunofluorescence antibody titres of > 1/10. On the other hand, none of 14 patients with herpes simplex virus (HSV) infection and...

A total of 215 diabetic children were screened for coeliac disease by determination of class specific serum reticulin antibody. Nine children were positive for reticulin antibody and all underwent biopsy of the small intestine. Four new cases of coeliac disease were found; all of these children had IgA reticulin antibody. Two of three other children with a low titre of IgA reticulin antibody ha...

the immounological responses to s. aureus cell wall antigens, namely crude or whole cell, teichoic acid (ta) peptidoglycan prepared in conventional way (cpg), cell wall (cw), lipoteichoic acid (lta) were investigated by number of immunological methods e.g. ria, elisa, immunodiffusion and western blotting techniques.also a method for preparation of peptidoglycan (mpg) was modified and used as va...

objective(s):hyperglycemia worsens the neuronal death induced by cerebral ischemia. previous studies demonstrated that diabetic hyperglycemia suppressed the expression of heat shock protein 70 and 60 (hsp70 and 60) in the liver. igg antibody titres against heat shock protein 27 (anti hsp27) were measured to determine whether hyperglycemia exacerbates ischemic brain damage by suppressing the exp...

The time interval between administering the serum and the virus was found to influence the results of the in vivo mouse protection test for foot-and-mouth disease antibodies. In particular, for both IgG and IgM antibodies to strain A12 virus, the mouse protection index increased from zero to a maximum at about 6 h and remained high for at least five days. Variations in the antiserum concentrati...

OBJECTIVES To determine the prognosis in patients with Lambert-Eaton myasthenic syndrome (LEMS) without small cell lung cancer (SCLC), and to analyse longitudinal clinical, electrophysiological, and immunological data on each patient to establish prognostic factors for long term outcome. METHODS The retrospective and part prospective study of 47 patients with LEMS was undertaken from data rec...

The P System antigens have been detected in numerous parasites, bacteria and viruses, nevertheless the clinical significance is still unknown. The aim was to study the presence of P1 antigenic determiners in A. lumbricoides extracts by means of the use of 6 different monoclonal antibodies of well-known concentrations and Ig class. We worked with 14 A. lumbricoides extracts. Inhibition Agglutina...
