Acute Hypoxemia in Rabbits
We studied the effect of pulmonary afferent activity on the heart rate response to a progressive, isocapnic decrease in oxygen saturation (Sao2) in anesthetized rabbits. To abolish the effect of rapidly adapting receptors, we used inhaled bupivacaine aerosol, and to abolish the effect of slowly adapting stretch receptor activity, we used sulfur dioxide insufflation. The heart rate (HR) response...
متن کاملMonitoring of experimental arthritis in rabbits.
The effect of ambient temperature and air flow on the radiometric measurement of experimental arthritis in rabbit knee joints has been studied. Temperature changes due to inflammation in such joints could be detected up to 70 days after induction of the arthritis by the use of radiometry. The method has been used to quantitate the anti-inflammatory activity of intra-articularly injected cortiso...
متن کاملDextran sulphate induced arthritis in rabbits.
Persistent effects of a short course of intra-articular dextran sulphate, dextrans, or chondroitin sulphate were examined in rabbit knees. Only dextran sulphate produced gross arthritis, associated with high synovial acid phosphatase and beta-glucuronidase activities. Synovial degradative capacity in synovium-cartilage cocultures was increased 2-fold by dextran sulphate and 1.5-fold by chondroi...
متن کاملThe Nature of the Immunologic Inadequacy of Neonatal Rabbits
It has been shown that cells from neonatal rabbits are capable of producing considerable amounts of antibody after exposure to antigen in vitro and transfer to x-radiated adult recipients. This suggests that the immunological inadequacy of these neonates is not dependent primarily upon the lack of cells capable of antibody formation. Both in vitro sensitized neonatal lymphoid cells and in vivo ...
متن کاملImmunologic Factors in Acute Rheumatic Fever Compared to Rheumatic Heart Disease
Background/Objective: To clarify the state of different immunologic factors in patients with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) compared to healthy individuals.Patients and Methods: Patients with ARF (#21), patients with RHD six months after the onset of ARF (#19), and healthy children from the same age group with normal physical examination and no history of pharyngi...
