Johne's disease (JD) caused by Mycobacterium avium subspecies paratuberculosis (MAP) is a major threat to the dairy industry and possibly some cases of Crohn's disease in humans. A MAP vaccine that reduced of clinical disease and/or reduced fecal shedding would aid in the control of JD. The objectives of this study were (1) to evaluate the efficacy of 5(More)
Haptoglobin phenotypes have been determined in 30 chronic lymphatic leukaemia patients and concentrations determined in 21 of these. The number ofHpl phenotypes is slightly raised but not significantly so compared with a control population and is the same as that in first-degree relatives. Haptoglobin concentrations show higher concentrations in Hpl than(More)
The aims of this study were to describe 42 cases of Clostridium perfringens type-D enterotoxaemia in cattle seen between 2003 and 2014 and to determine the diagnostic value of detecting epsilon toxin in bovine intestinal content. All cases in the series had histological brain changes considered pathognomonic for C. perfringens type-D enterotoxaemia in sheep(More)
Red blood cell delta-aminolevulinic acid dehydratase (RBC-ALAD) activity has proven to be a sensitive indicator of lead exposure in humans. The depressed enzyme activity and its negative correlation to blood lead concentrations are well-known effects of lead exposure in man. The sensitivity of RBC-ALAD activity in young Japanese quail exposed to low levels(More)
The objective of this study was to compare the pregnancy rate after timed artificial insemination (P/TAI) in dairy heifers treated with 4- versus 5-day Co-Synch + controlled internal drug release (CIDR) protocols. A total of 120 Holstein heifers were randomly assigned to one of two groups. The heifers received an intravaginal CIDR insert containing 1.38 g(More)
The pharmacokinetics of five pre-mixed insulin preparations in the ratio of soluble to NPH insulin of 10:90, 20:80, 30:70, 40:60 and 50:50, were examined in a two part study in fasting healthy subjects. Each received by bolus subcutaneous injection into the anterior abdominal wall, on separate occasions one to two weeks apart, 20U of each of three pre-mixed(More)
Because pulmonary B-cell non-Hodgkin's lymphomas are now thought to arise in bronchial mucosa-associated lymphoid tissue (MALT), 45 patients with pulmonary B-cell lymphomas were reviewed to look for aetiological factors in the lung. It was found that six of the 45 lymphomas arose in patients with systemic autoimmune disease, which in three patients involved(More)
Five hundred and eighty-five patients with moderate asthma, currently receiving 400-1000 micrograms day-1 of an inhaled corticosteroid, were treated for 6 weeks in a double-blind, randomized, parallel group study with either 500 micrograms day-1 fluticasone propionate as a dry powder via a Diskhaler inhaler, 500 micrograms day-1 fluticasone propionate via a(More)
