A double-blind study with intra-individual comparisons was carried out to investigate the effects of 15 mg of (8r)-3alpha-hydroxy-8-isopropyl-1alphaH-tropanium bromide(+/-)-tropate (Sch 1000), 15 mg Sch 1000 + 10 mg oxazepam, 10 mg oxazepam and placebo with oral administration in randomized sequence on gastric juice volume, amount of acid, concentration and pH values in 12 healthy volunteers. The secretion parameters were measured during a 1-h basal period and a 2-h stimulation period. The gastric juice was obtained in 15 min portions via stomach tube. Stimulation was effected by 1 mug/kg/h pentagastrin via drip infusion. The Friedman test was used for the comparative statistical evaluation, and individual comparisons were carried out by means of the Wilcoxon test (pair-differences rank). The results show that Sch 1000 and Sch 1000 + oxazepam were equal in effect on basal and stimulated secretion volume. As compared with placebo, it was not possible to establish an effect on secretion volume for oxazepam alone. Sch 1000 and Sch 1000 + oxazepam were found to be equipotent in reducing the amount of basal acid, while oxazepam reduced this quantity only during the first 30 min of basal secretion. None of the three active preparations was capable of inhibiting the stimulated acid, although both Sch 1000 preparations produced a clear trend towards lowered mean values. During the basal secretion period, all three test preparations had an inhibiting action on acid concentration, but none of them had a significant effect during the stimulation period. The pH value was savely increased only by Sch 1000 and Sch 1000 + oxazepam, and this even only during the basal period. The results are discussed.
Verbruggen, R. Subtilopeptidase A isoenzyme system. Interaction with serum components and its importance for quantitative immunoelectrophoresis. Biochem J 151, 1, 149-55 (1975).Abstract
A method was developed which involved electroimmunoassay and crossed immunoelectrophoresis of subtilopeptidase A (EC Initial trials with unfractionated antiserum were not successful and interaction of the enzyme with non-immunoglobulin serum components were shown to be the cause of the failures. Quantitative immunoelectrophoresis was possible when purified immunoglobulins were used. A pH of 6.5 (lower than the usual pH 8.6) was necessary to obtain a proper baseline definition. Subtilopeptidase A was confirmed as a multiple isoenzyme system. Qualitative inter-batch variations were detected. Di-isopropyl phosphorofluoridate inhibition altered the electrophoretic pattern, but no loss of antigenic determinants was observed.
Vasina, I.G., Frolov, E.P. & Serebriakov, N.G. [Sympathico-adrenal system activity in a primary immune response]. Zh Mikrobiol Epidemiol Immunobiol 9, 88-92 (1975).Abstract
Experiments were carried out on linear mice immunized with sheep erythrocytes; it was found that the primary immune respose developed against the background of significant changes in the state of the sympathico-adrenal system, whose activity was determined by the dynamics of catecholamines in the blood and in the tissues of a number of organs, including the thymus, the spleen and the lymph nodes. By comparing the value of specific and neurohumoral indices it was revealed that the neurohumoral shifts preceded the maximal development of the immune response. On the example of studying the catecholamine dynamics the opinion on a close association between the state of the regulatory mechanisms and the effector formations responsible for the formation of specific immunological reactions was confirmed. It is suggested that a full-value immunological response developed on condition of activation of the sympathico-adrenal system.
