(1) the vessels may transude serum(2) In animals with normal plasma protein concentrations fluid began to transude into the lungs when the left atrial pressure rose above an average of 24 mm.(3) Interstitial edema results from transudation of fluid through the capillary walls into the interstitium around the vessels which can render normally indistinct vessels distinct.(4) The formation of the transudate / exudates and casts in the airway are the result of a number of factors.(5) The greatest degree of histologic changes were observed in animals receiving hypercapnia + LPS, where significant alveolar transudation , septal edema, and extravasation of red blood cells occurred.(6) However, in contrast to thermal burns, the fluid losses do not occur until the blisters form and the fluid lost is a transudate , which means protein losses are less.(7) The increased transudate burdening the lymphatic system results in interstitial edema.(8) In view of all the atypical features, it was sensible to aspirate pleural fluid to see if it was a transudate or an exudate.(9) The right pleural effusion was tapped, and it was demonstrated to be a transudate by chemistry.(10) It is characterized by a massive transudation of a protein-rich fluid from the vascular compartment into the peritoneal, pleural, or, to a lesser extent, pericardial cavities.(11) Urticarial lesions are the result of capillary vasodilation followed by transudation of fluid into the superficial dermis.(12) It is given by injection and stimulates serum IgM, IgG, and IgA, but not secretory IgA, immunity being induced by antibody transuding into the oropharynx.(13) Pulmonary complications, such as pleural effusion, result from retroperitoneal transudation of fluid from the swollen pancreas.(14) Pleural fluid LDH is the most accurate overall criterion for classifying pleural effusions into exudates and transudates .(15) This condition is due to haemorrhages into the stroma of the iris, the fluid part of the blood transuding into the anterior chamber.(16) Alternatively, serum antibody may be transuded into tracheal secretion or reach mucosal surface in inflammatory exudates.
