[Q]: Abstract: Prazosin, an antagonist of the alpha 1-adrenoceptor, has been found to suppress the clinical and histologic expression of experimental autoimmune encephalomyelitis (EAE) in the Lewis rat. This effect appears to be specific for the alpha 1-receptor. To determine the effect of this drug on vascular permeability to serum proteins and inflammatory cells, leakage of serum proteins into the central nervous system (CNS) was measured with [125I]albumin, and quantitation of cellular inflammation was determined by an estimation of total DNA. The results show that in both actively induced and passively transferred models of the disease, treatment with prazosin significantly suppresses leakage of serum proteins into the CNS but does not significantly suppress the increase of DNA. The results of the [125I]albumin studies additionally support the conclusion that the extent of vascular permeability to serum proteins in the spinal cord is a significant correlate of clinical disease. The results of the DNA estimation were at variance with the histologic evidence of cellular infiltration. We conclude that treatment with prazosin has a significant effect on the development of vascular edema in EAE. These results additionally validate a role for the adrenergic receptor in the development of EAE, and support the hypothesis that the primary site of action of prazosin is on the vascular alpha 1-adrenoceptor.

[Q]: Abstract: In 14 healthy male subjects we studied the effects of rib cage and abdominal strapping on lung volumes, airway resistance (Raw), and total respiratory resistance (Rrs) and reactance (Xrs). Rib cage, as well as abdominal, strapping caused a significant decrease in vital capacity (respectively, -36 and -34%), total lung capacity (TLC) (-31 and -27%), functional residual capacity (FRC) (-28 and -28%), and expiratory reserve volume (-40 and -48%) and an increase in specific airway conductance (+24 and +30%) and in maximal expiratory flow at 50% of control TLC (+47 and +42%). The decrease of residual volume (RV) was significant (-12%) with rib cage strapping only. Abdominal strapping resulted in a minor overall increase in Rrs, whereas rib cage strapping produced a more marked increase at low frequencies; thus a frequency dependence of Rrs was induced. A similar pattern, but with lower absolute values, of Rrs was obtained by thoracic strapping when the subject was breathing at control FRC. Xrs was decreased, especially at low frequencies, with abdominal strapping and even more with thoracic strapping; thus the resonant frequency of the respiratory system was shifted toward higher frequencies. Partitioning Rrs and Xrs into resistance and reactance of lungs and chest wall demonstrated that the different effects of chest wall and abdominal strapping on Rrs and Xrs reflect changes mainly of chest wall mechanics.

[Q]: Abstract: Eighteen cancer patients receiving intensive chemotherapy developed leukopenia, fever, dysphagia, and oropharyngeal soreness. Superficial esophageal ulceration suggestive of esophagitis was demonstrated by radiographic examination in 33% of the patients (5/15). Upper gastrointestinal endoscopy revealed superficial ulceration and white mucosal patches in all patients. There was no morbidity associated with the endoscopic procedures. Sixty-one percent of the patients (11/18) had monilia albicans cultured from the oropharyngeal cavity, and 50% (9/18) had monilia cultured from the esophageal lesions. The evolution of the esophagitis correlated well with the survival of the patients. The monilial esophagitis persisted in six patients who all died within 24 days of systemic moniliasis. After initial improvement five additional patients succumbed; three of them from severe fungal infection. There was resolution of the esophagitis in the remaining seven patients who survived longer. However, two of them had recurrent monilial esophagitis and succumbed to systemic candidiasis. The other five have remained free of esophagitis, their underlying malignancies have remained under control, and so far they have survived an average of one and a half years. Endoscopy is more accurate than radiography in detecting postchemotherapy esophagitis. This complication can be fatal, since it is often followed by systemic candidiasis.
