Throat and bronchoscopy specimens for mycoplasma isolation studies were collected from 22 patients with chronic bronchitis and 20 patients without chronic bronchitis. Twenty-six of 50 patients attending a chronic bronchitis clinic had throat, nasal, or sputum specimens collected for attempted mycoplasma isolation, and all of these patients had multiple serum samples taken for mycoplasma antibod...

During a 12-month period, 40 146 blood donors were tested for the presence of high titre antitetanus antibodies. An attempt has been made to define the most suitable donors, those with antitetanus antibody titres of 4 IU/ml or above, by virtue of titre, sex, location, and length of time since most recent immunisation. Particular note is made of those donors from university sessions. Towards th...

BACKGROUND No conventional immunosuppressive agent preferentially inhibits antibody production. Studies in experimental animals and in human cells in vitro suggested mycophenolate mofetil (MMF) might have such an effect. If this was the case in vivo it could have significant implications in terms of both MMF toxicity and the rational design of immunotherapeutic regimens. METHODS Subjects were...

this case report demonstrates fatal gastrointestinal vasculitis as a rare presentation of systemic lupus erythematosus. a 34-year-old woman presented with abdominal pain and diarrhea. anti nuclear antibody was positive and high titre of anti-ds dna antibody was also reported. treatment with corticosteroid and supportive cares were started; however, her condition worsened. eventually, she was co...

The fluorescent treponemal antibody (FTA-200) test has been shown to detect at least two types of antibody in syphilitic serum; one of these, which can be removed by absorption with Reiter treponemes, is thought to be a group antibody which reacts with an antigen shared by Treponema pallidum and other treponemes (Deacon and Hunter, 1962). A second antibody, which remains after such an absorptio...

OBJECTIVE The immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. MATERIALS AND METHOD The essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. The essential oils were tested for hypersensitivity and hemagglutination reaction...

BACKGROUND Maternally HIV-exposed (mHIV-EU) infants have poor health even without HIV-1 infection. The responses to vaccination are less well defined. Immunity to oral Poliovirus vaccine (OPV) was studied in Zambian infants participating in a randomised controlled trial of micronutrient fortification to improve child health. METHOD Maternally HIV-unexposed and mHIV-EU infants were recruited a...

1. The antibody response of rabbits following intracutaneous injections of pneumococcus or of streptococcus vaccines showed three phases. (a) Within 5 to 12 days following a single injection of pneumococcus or of streptococcus vaccine, high antibody titres were detected in extracts from the site of the injection into the skin, the spleen, the bone marrow, and the liver. Occasionally, antibodies...
