[EX 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.

[EX Q]: Abstract: The objective of this study was to find naturally occurring anti-idiotypic (anti-Id) antibodies to anti-human thyroglobulin (anti-hTg) idiotype in sera of patients with autoimmune thyroid disease. Sera from patients with Hashimoto's thyroiditis (HT), Graves' disease (GD), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) and sera from normal subjects were tested for the presence of anti-Id antibodies against mouse anti-hTg monoclonal antibodies (McAb) in indirect ELISA and in indirect solid-phase RIA. Microtitration plates were coated with six McAb, five of them directed against different epitopes on hTg molecule, and then incubated with patients' sera. The bound antibody was detected with either peroxidase or 125I-labeled anti-human IgG. The specific positive reaction was observed in four of 40 patients with HT, in two of 26 patients with GD, in seven of 58 patients with RA, and in none of 20 normal subjects. The detected binding was due to the presence of anti-hTg anti-Id antibodies and not to Tg-anti-Tg circulating immune complexes, as the positive sera did not contain hTg when resolved on SDS-PAGE, nor did they bind to all anti-hTg McAb tested. The binding was dose dependent, and titers of anti-Id antibodies varied from 1:243 to 1:2187. The binding could be inhibited up to 50% by hTg, but not by the thyroid microsomal antigen, indicating that some of those anti-Id might represent the internal image of the antigen. Serum from the patient 3403, showing the strongest reactivity against McAb A-3, was chosen for IgG purification and F(ab')2 fragment isolation. The 3403 F(ab')2 fragment, but not the Fc fragment, was found to react specifically with four mouse anti-hTg McAb but not with the control mouse IgG. Thus, the obtained results permit the conclusion that anti-hTg anti-Id antibodies could occur naturally during the course of thyroid autoimmune disorders.

[EX Q]: Abstract: Twenty-two patients with recurrent nose bleeds and varicose vessels on the nasal septum were subjected to transection of the vessels and followed-up for 2 years. One month after the operation, it was not possible to identify the original vessels. In other locations new varicose vessels began to appear after 1 month, and at the end of the follow-up period were observed on 9 out of 10 operated sides. The transection resulted in an immediate decrease in the frequency of nose bleeds and at the end of the control period 12 (55%) of the patients had had less than 4 bleeds during the previous year in spite of the observed rapid formation of new vessels. Mucosal atrophy with symptoms of increased nasal crusting occurred in 3 patients. Transection of varicose vessels in patients with nose bleeds leads to a decrease in the number of bleeds.
