Joint fluid pressure in chronic knee effusions.
With sterile precautions and after infiltration with local anaesthetic, a special type of needle was introduced into the lateral aspect of the knee near the upper border of the patella. This needle (S.W.G. 18, Down Bros., with a short bevel and perforations made in the sides 0 5 cm. from the point to prevent blockage) had a tap and a side-arm. A manometer filled with normal saline was attached ...
متن کاملChemotactic effect of joint effusions.
This paper reports the incidence of chemotactic activity of joint effusions obtained from several diseases involving joints. Ward and Zvaifler (1971) found that such activity was present in the majority of effusions in rheumatoid arthritis, but also in some cases of other nonspecified forms of inflammatory arthritis, gout, and osteoarthritis. These authors used rabbit neutrophil polymorphs to a...
متن کاملPressure Gradients without Obstruction
OBSTRUCTION to left ventricular outflow has been considered a characteristic and functionally important feature of "hypertrophic subaortic stenosis." The presence of obstruction has been inferred from the finding of a pressure gradient within the left ventricle during catheterization of the left heart in certain patients with idiopathic left ventricular hypertrophy. Indeed, the disease was not ...
متن کاملBrownian motion, hydrodynamics, and the osmotic pressure
It is shown that the osmotic pressure of a colloidal dispersion can be interpreted as the isotropic part of the macroscopic particle stress in the suspension. The particle stress is in turn expressible in terms of hydrodynamic interactions among the suspended particles. Thus, there is a completely mechanical definition of the osmotic pressure, just as there is for the pressure in a molecular fl...
متن کاملInfluence of natural organic matter fouling and osmotic backwash on pressure retarded osmosis energy production from natural salinity gradients.
Pressure retarded osmosis (PRO) has the potential to produce clean, renewable energy from natural salinity gradients. However, membrane fouling can lead to diminished water flux productivity, thus reducing the extractable energy. This study investigates organic fouling and osmotic backwash cleaning in PRO and the resulting impact on projected power generation. Fabricated thin-film composite mem...
