    Notes: Crossed immunoelectrophoresis and crossed radio-immunoelectrophoresis techniques have been employed for analysis of extracts of various rabbit source materials to identify rabbit allergens in addition to the already described Antigen R1 (AgR1). Urine and dander extracts were found to contain only low levels of AgR1 and its presence in urine was as a contaminant due to mode of collection – it was not present in urine collected directly from the bladder. Other allergens were only recognised by highly rabbit-sensitive individuals, one in particular (Ag2) being present in several source materials. Serum albumin proved to be of minor allergenic importance and except for dander its presence was only in minimal amounts. As both AgR1 and Ag2 are significant components in extracts of fur and dust these extracts are therefore most recommended for use in investigations of individuals sensitive to rabbits.

    Notes: In 1985 and 1990 postal questionnaires were sent to anaesthetic senior registrars in training in the United Kingdom to determine the extent of higher specialist training in chronic pain management. There were wide variations in training and experience amongst senior registrars. Overall there was little change between 1985 and 1990. In particular the number of anaesthetic senior registrars who felt equipped to undertake a consultant post with an interest in chronic pain management had not increased.

    Notes: Blood samples were obtained from fetuses and premature babies (n=51) (15-34 weeks gestation) to determine at what stage the fetal immune system was able to produce a positive proliferative response to common allergens. Peripheral blood mononuclear cells (PB MC) were stimulated with the mitogen, phytohaemagglutinin (PHA), and the allergens, house dust mite, cat fur. birch tree pollen, β-lactoglobulin, ovalbumin and bee venom (mellitin). Results were expressed as ratios of stimulated to unstimulated 3H thymidine incorporation, and as percent positive responders. There was an increase in proliferation ratio which correlated with increasing gestational age for PHA (p 〈 0.0001), cat fur (p=0.042), birch pollen (p=0.022) and β-lactoglobulin (p=0, 006). The point in gestation when cells from some individuals began responding to the allergens with a ratio of 2. 0 was at approximately 22 weeks. PBMC proliferative response ratios were higher from samples from babies 〉 22 weeks gestation compared to 〈 22 weeks for the mitogen and all allergens, except mellitin. There was also a greater proportion of positive responders from samples 〉 22 weeks compared to 〈 22 weeks for the mitogen and all allergens, except mellitin. Maternal exposure to birch pollen, which has a discrete season, was assessed to determine whether exposure had occurred at 22 weeks gestation or beyond. Results showed a higher prolifera tive response in infant cells stimulated with birch pollen (p=0.005) and higher proportion of positive responders (p=0.01) in the group of babies whose mothers had been exposed to hirch pollen beyond 22 weeks, compared to those whose mothers had not been so exposed. These results suggest that in utero fetal exposure to an allergen from around 22 weeks gestation may result in primary sensitisation to that allergen, leading to positive proliferative responses, at birth.

    Notes: The homes of 68 atopic asthmatic children were studied to estimate the concentrations of perennial and seasonal aeroallergens (Der pl, Fel d1, grass pollen, tree pollen, Cladosporium, Aspergillaceae and Alternaria) to which children were likely to have been exposed during their first few months of life, by sampling in the child's month of birth. There was a strong association between the presence or absence of the house dust mite allergen Der p1 in the air with the skin test and IgE antibody test results (p 〈 0.001), with a similar association for cat allergen Pel d 1 (p 〈 0.01), when using a low volume sampler (equivalent to the minute tidal volume of a small baby). No significant correlation was found between levels of allergen in carpet dust and air in the same room. There was a strong indication that the presence of a cat at birth was linked with a higher risk of development of allergy to cat, but high levels of Fel d 1 were sometimes found in homes even when there was no cat present, indicating that allergen may be introduced from other sources. The levels of tree pollen were significantly higher in the homes of tree pollen-allergic children than in the homes of patients without this sensitivity (p 〈 0.01); and the degree of sensitivity, determined by RAST, correlated significantly to the level of tree pollen in the home (p 〈 0.001). However, no relationship was found between specific sensitivity and the levels of Cladosporium, Aspergillaceae, Alternaria or grass pollen measured in the homes. The effect of high allergen exposure was most prominent in children under 7 yr and not beyond that age.

    The effect of co-induction with midazolam upon recovery from propofol infusion anaesthesia (1997)

    Notes: Forty-eight patients undergoing day-case anaesthesia were asked to complete pre- and postoperative tests of psychomotor function in order to study the influence of co-induction with midazolam in conjunction with propofol/alfentanil anaesthesia on postoperative psychomotor recovery. The study was placebo controlled and double blind with patients receiving either 0.03 mgkg−1 of midazolam or saline 2 min before induction of anaesthesia with propofol and alfentanil. Patients who underwent co-induction with midazolam had significantly impaired concentration and rapidity of response but improved accuracy and vigilance when compared with those who received saline. The study confirmed that co-induction with a subanaesthetic dose of midazolam reduced the induction dose of propofol by up to 50%. We conclude that co-induction with midazolam reduces psychomotor recovery in the immediate postoperative phase following propofol infusion anaesthesia.

    Notes: Backgrottnd Basophils arc circulaling, secretory grunulocytes that are generally considered to be end-stage cells. In one species of guinea-pigs, basophilic leucocytes have been shown to recover from stimulated secretion in short-term cultures. Similar studies have not been done using human basophils.Objective The purpose of this study was to examine human hasophils in short-term recovery intervals following stimulation of secretion to determine whether visual evidence of recovery occurred.Methods We examined the ultrastrucural morphology of early recovery (l0 min-6h) of human basophils following secretion stimulated by formyl-mcthionyl-lcucyl-phenyl-alanine (FMLP). A combined technique for electron microscopy consisted of postfixation exposure to cationizcd ferritin and reduced osmium, providing maximum quality images and allowing identification of intracellular spaces/organelles that opened to the cell surface, often out of the plane of section.Results The ultrastructural evaluation revealed that control basophils (0 time–6h) did not undergo regulated secretion or develop the morphologies associated with recovery following secretion. FMLP-stimulated basophils underwent an overlapping continuum of piecemeal degranulation - anaphylactic degranutation (0 time- I min), producing vesicle- and granule-free, completely degranulated, viable, mature basophils with polylobed nuclei. The early recovery period (10 min-h) following FMLP stimulation was characterized by reconstitution of granules. Morphological mechanisms for granule reconstitution included a mixture of conservation, condensation, and synthetic events.Coticlttsion Human basophils, like guinea pig basophils, have the polential to recover from regulated secretion.

    Is deficiency of interferon gamma production by allergen triggered cord blood cells a predictor of atopic eczema? (1994)

    Notes: Abstract. Peripheral blood mononuclear cell proliferative responses and interferon-γ product ion to anti-CD3, cat fur extract, betalactoglobulin and ovalbumin were determined al birth in a group of 34 babies born to families where at least one parent was; atopic. The development of atopic eczema with positive allergy skin-prick tests to cows’ milk and egg at 1 year of age, where the symptoms improved on an egg and milk-free diet, was significantly associated with raised proliferative responses and defective IFN-γ production to stimulation with betalactoglobulin with a trend for similar responses to ovalbumin. This was not observed in those who did not develop atopic eczema or those with atopic eczema not associated with foods. Responses to cat fur extract were not significantly different between those with and without atopic eczema. This has important implications for the prediction at birth, not only of the probability of being allergic, but also of the specific allergens which will cause problems. The implementation of specific targeted allergen avoidance during the critical period in infancy, therefore, should be more easily applied and should facilitate attempts to prevent disease.

    Airway function correlates with circulating eosinophil, but not mast cell, markers of inflammation in childhood asthma (1996)

    Notes: Background Lung function tests, including forced expiratory volume in one second (FEV1), forced expiratory flow at 25–75% of vital capacity (FEF25–75%) and provocation concentrations of histamine which reduce FEV] by 20% (PC20), are used as indicators of airway form and function in bronchial asthma. Recently, markers of eosinophil activation in bronchial lavage and serum have been suggested as a measure of eosinophil mediated inflammation in the airways. These include eosinophil cationic protein (ECP), eosinophil protein X (EPX) (also known as eosinophil derived neuro-toxin) and eosinophil peroxidase (EPO). Similarly, serum tryptase has been used as a marker of mast cell activation in systemic anaphylaxis.Objectives We measured both sets of indices in a group of children with moderately severe asthma to assess the contribution of eosinophil and mast cell mediated events to airflow limitation and bronchial hyperresponsiveness.Methods Forty-eight children aged 5–10 years had spirometric assessments, histamine challenges and blood sampling on the same occasion. After analysis of sera, the indices were compared.Results The eosinophil markers ECP and EPX correlated very well with each other. They showed a moderate negative correlation with PC20 for histamine. EPX was also found to negatively correlate with FEV, and FEF25–75%. Serum tryptase levels showed no such correlates with airway function.Conclusion These results suggest that serum markers of eosinophil activation correlate with airway function in childhood asthma, and may be of value in assessing the severity of the disease. It further supports the notion that childhood asthma has a similar immunopathology to that occurring in adults, with predominance of eosinophil mediated inflammation.
