Histamin in der Interstitialfl�ssigkeit der befallenen und klinisch nicht befallenen Haut bei chronisch rezidivierender Urticaria
1979
Bei 8 Patienten mit idiopathischer chronisch rezidivierender Urticaria wurden in der Periumbilicalregion Saugblasen gleichzeitig auf frischen urticariellen Herden und der unveranderten Haut daneben produziert und Histamin in der Blasenflussigkeit bestimmt. Hierzu wurde die von Siraganian entwickelte Methode der Autoanalyzer-Technik in modifizierter Form verwendet. Die Histaminspiegel lagen bei diesen Patienten in unveranderter Haut in derselben Grosenordnung wie bei 10 Normalpersonen, wahrend alle 8 Urticaria-Patienten hohere Histamin-Werte in den Urticae verglichen mit der nicht befallenen Haut aufwiesen; bei 4 der Patienten waren diese Unterschiede jedoch nur gering ausgepragt.
Physical forces in blister formation. The role of colloid osmotic pressure and of total osmolality in fluid migration into the rising blister.
1978
The physical forces operative in the fluid migration from the interstitial spaces into the blister cleft have not been directly measured until now. The colloid osmotic pressure and the total osmolality were determined in suction blister fluid after mild suction blister production by a modified “Dermovac” and in blister fluid of patients with dermatitis herpetiformis, bullous allergic contact dermatitis and pemphigus vulgaris and in the sera of healthy persons. The colloid osmotic pressure was measured by means of a recently developed osmometer with a semipermeable membrane between 2 chambers, one of them filled with Ringer solution, the other with the blister fluid or serum sample. The nega…
Background of Physiology in the Pulmonary Circulation
1980
This paper has to be considered as an introduction to the physiology of pulmonary circulation: it can only introduce to some aspects of this topic which will be dealt with in more detail in the following presentations and actually are widely discussed in the literature.
Pericardium of the frog,Rana esculenta,is morphologically designed as a lymphatic space
2003
The importance of the pericardium and the pericardial fluid (PF) in the control of cardiac function has emerged over the past few years. Despite the acknowledgment that amphibians are exposed to both dehydration and excessive water accumulation, nothing is known about their pericardial structure and the morphological basis of the PF formation. We have studied the parietal pericardium (PP) morphology in Rana esculenta by electron microscopy. SEM images of the inner surface, which lines the pericardial cavity, revealed the presence of large vesicles and many small circular openings. TEM observations showed that the PP is made up of an inner mesothelial lining, often constituted by two layers …
Relationship of Cerebral Blood Flow Disturbances with Brain Oedema Formation
1993
Brain oedema is an important factor which compromises maintenance of the cerebral blood flow. Conversely, primary blood flow disturbances are leading to brain oedema. The mechanisms underlying blood flow impairment by brain oedema are associated with an increased regional tissue pressure in proportion to the degree of water accumulation in the parenchyma. The release of vasoactive mediator compounds might be considered in addition. Primary disturbances of the cerebral blood flow, such as focal or global cerebral ischaemia are leading to an increased cerebral water content. A decrease of the cerebral blood flow to ca. 40% of normal or below has been found to result in the development of brai…
Microdialysis-Assessed Exercised Muscle Reveals Localized and Differential IGFBP Responses to Unilateral Stretch Shortening Cycle Exercise
2020
Microdialysis allows for a preview into local muscle metabolism and can provide physiological insight that blood measurements cannot. Purpose: To examine the potential differential IGF-I system regulation in interstitial fluid during unilateral stretch shortening cycle exercise. Methods: 10 men (26 ± 7 year) performed unilateral jumping [stretch shortening cycle (SSC) exercise at 50% of optimal jump height] until volitional fatigue on a sled apparatus. Biological sampling took place using a catheter inserted into an antecubital vein (serum), and 100 kDa microdialysis probes inserted into the thigh muscle of each exercise/control leg (dialysate). Serum was drawn before (Pre; −3 h) and after …
