Upregulation of MICA on high-grade invasive operable breast carcinoma.

The MHC class I chain-related gene A (MICA) is frequently expressed on the surface of intestinal epithelium and by many epithelial tumours. MICA is a stress-induced antigen which was identified as an activator of natural killer cells via interaction with the NKG2D receptor. We have raised a rabbit polyclonal antibody against a synthetic peptide that recognises denatured MICA on both Western blots and in formalin-fixed paraffin-embedded sections.

Tazobactam-induced haemolytic anaemia, possibly caused by non-immunological adsorption of IgG onto patient's red cells.

A patient with pneumonia was treated with Tazocin (piperacillin/tazobactam). However, the expected haemoglobin (Hb) increment after transfusion was not achieved. Plasma bilirubin and lactate dehydrogenase were raised.

Role of elevated plasma soluble ICAM-1 and bronchial lavage fluid IL-8 levels as markers of chronic lung disease in premature infants.

Background: Pulmonary neutrophilia characterises both the relatively transient inflammation associated with infant respiratory distress syndrome (IRDS) and the persistent inflammation of chronic lung disease. The possibility that persistently raised markers of inflammation indicate the development of chronic lung disease in low birth weight (< 1730 g) preterm (< 31 weeks) infants was therefore investigated.

Methods: Soluble ICAM-1 (sICAM-1) levels in plasma, and interleukin (IL)-8 and myeloperoxidase (MPO) levels in bronchial lavage fluid (BLF) obtained from 17 infants on days 1, 5, and 14 following birth were measured and correlations with the number of neutrophils in BLF sought.
