Rabbits infected intravenously with virulent mammalian tubercle bacilli have in a majority of cases developed circulating antibodies to a slight but appreciable degree. The increase in titer was detected in one group of rabbits within the 2nd or 3rd week, in others during the 2nd month of infection. Rabbits with residual pulmonary foci, resulting from infection 6 months or more previously with ...

A method is presented for the decontamination, liquefaction, and concentration of sputum specimens that are in transport more than 24 h. The method is inexpensive, and culture results compare well with those obtained with the accepted N-acetyl-L-cysteine and sodium hydroxide method for the isolation of tubercle bacilli. The working solution, 1% cetylpyridinium chloride and 2% sodium chloride, i...

conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...

During studies on the effect of isoniazid on the dehydrogenase activity of tubercle bacilli, the surprising observation was made that the bacteria which had been exposed to the drug reduced methylene blue or triphenyltetrazolium chloride at a much faster rate than did the untreated bacteria. The present report describes this phenomenon in detail and our attempts to elucidate its mechanism and s...

A previously reported form of microbial persistence whereby large populations of tubercle bacilli can be made to "vanish" uniformly from the tissues of mice has been shown to occur generally throughout each group of animals subjected to the experimental procedure; it does not reflect the eradication of the bacilli in the majority of animals with their persistence and ultimate revival in only a ...

Many migrating insects rely on the plane of sky polarization as a cue to detect spatial directions. Desert locusts (Schistocerca gregaria), like other insects, perceive polarized light through specialized photoreceptors in a dorsal eye region. Desert locusts occur in two phases: a gregarious swarming phase, which migrates during the day, and a solitarious nocturnal phase. Neurons in a small bra...

BACKGROUND While the anatomy of the medial part of the knee has been described qualitatively, quantitative descriptions of the attachment sites of the main medial knee structures have not been reported. The purpose of the present study was to verify the qualitative anatomy of medial knee structures and to perform a quantitative evaluation of their anatomic attachment sites as well as their rela...

Olfactory information is processed by a diverse group of interconnected forebrain regions. Most efforts to define the cellular mechanisms involved in processing olfactory information have been focused on understanding the function of the olfactory bulb, the primary second-order olfactory region, and its principal target, the piriform cortex. However, the olfactory bulb also projects to other ta...

Injury to the structures of the medial elbow is common among baseball players. The injury can result from repeated valgus stress of the elbow. Several types of injury to the structures of the medial elbow have been reported.1 These injuries cause valgus instability and pain of medial aspect of the elbow during pitch.2e4 Avulsion fractures of the sublime tubercle of the ulna are rare and general...

Postoperative septicaemia with infective endocarditis is a recognized complication of open-heart surgery, in particular homograft or prosthetic replacement of cardiac valves. Several infective organisms, both bacterial and fungal, have been incriminated but infection due to tubercle bacilli has not, to our knowledge, been reported. The clinicopathological features of this condition are discusse...
