[Q]: Abstract: Intravenous cimetidine, 300 mg or 400 mg, or ranitidine, 50 mg, was administered as a single dose to 36 volunteers in a randomized, crossover fashion. Aspirates of gastric juice were obtained after dosing, and the pH, titratable acidity, gastric fluid volume, and gastric acid output were determined from baseline through 71/2 hours for each subject. Each intervention significantly increased pH and suppressed hydrogen ion concentration, gastric fluid volume, and gastric acid output. Both the magnitudes of the changes when compared with baseline and the time of the mean maximum effects were similar in all three drug regimens. The effect of all three interventions on gastric fluid volume and gastric acid output diminished sharply after 6 hours. The data indicate that the gastric secretory response to all three interventions did not differ substantially.

[Q]: Abstract: Twenty one cases of amyloidosis of the lower respiratory tract were seen at a single center. In three patients, multifocal bronchial amyloid plaques led to stenosis and atelectasis, and in two, small pseudotumor masses were an incidental bronchoscopic finding. Two patients had nodular parenchymal amyloidosis, in one of whom the lesions were progressive and in the other static. Fifteen patients had diffuse parenchymal amyloidosis. Two of these had severe interstitial involvement and died in respiratory failure; eight had congestive cardiac failure, and parenchymal amyloidosis was a post-mortem finding; two had senile cardiorespiratory amyloidosis, also found at autopsy; and in three, the amyloidosis was associated with malignancy. The degree of respiratory embarrassment seemed to be related to the amount of amyloid in the gas diffusion zones, irrespective of the etiology of amyloidosis.

[Q]: Abstract: It has been assumed that the molecular weight (MW) cut-off of a newly fabricated polysulfone capillary dialyzer (F60, Fresenius, FRG) is similar to that of the human glomerulus. We recently tested the device in vivo and found this not to be so, based on the device's ability to eliminate substances of a MW of 10,000 to 60,000 daltons. One of the reasons for this discrepancy was found to be the influence of secondary membrane formation on solute permeability. Endogenous marker substances of a defined MW (beta 2-microglobulin, myoglobin, RBP, alpha 1-microglobulin, acid alpha 1-glycoprotein, alpha 1-antitrypsin, prealbumin, and albumin were measured by laser nephelometry or radioimmune assay; sieving coefficients (SC) and protein eliminations were calculated for each low MW protein.
