To clarify the neural and humoral factors which control gastric receptive relaxation, the effects of various types of vagotomy or splanchnicotomy on receptive relaxation of the canine innervated corpus pouch were investigated. The influence of gastrin, histamine H1-receptor antagonist, and anti-histamine releasing agents on receptive relaxation were also(More)
In order to generate a reference value of aging, estimation of chronological age of healthy subjects was made by multiple regression analysis. It was shown that the estimated ages of hypertensive subjects by the formula used were significantly higher than their chronological ages. It was further observed that parameters representing various ability of(More)
In a previous paper, the authors reported that the kallikrein-like activity was eluted in alpha 2-macroglobulin fractions when patient's plasma was fractionated with Sephadex G-200 gel filtration. In order to clarify the characteristics of the kallikrein-like enzyme, enzyme isolation methods were investigated. Success was attained by the addition of 1 %(More)
This paper describes the method to estimate the true formation temperature using temperature recovery logging data after the well reach to total depth (T.D.). The method designated as "Curve-fitting method (CFM)" is based on mathematical model proposed by Middleton (1979, 1982). The accuracy and applicability of this method are evaluated with several field(More)
Papain treatment of human urinary trypsin inhibitor (UTI67; mol. wt. 43,000 by SDS-polyacrylamide gel electrophoresis, specific activity 1,897 U/mg protein) produced four new protease inhibitors, which were highly purified by gel chromatography on Sephadex G-100 and isoelectric focusing. The purified inhibitors (UTI26, UTI9-I, UTI9-II, and UTI9-III) were(More)
In order to clarify the role of histamine in the neuro-humoral excitatory mechanism in the stomach, the effect of cepharanthine (an inhibitory agent of histamine release from mast cells) on excitatory response of gastric movement and increase in gastric mucosal histamine content caused by nerve stimulation (vagus and splanchnic nerves) or administration of(More)
In the present study, a trypsin inhibitor was first extracted from lung cancer tissue and purified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. A final yield of 20 to 60 micrograms of inhibitor with a specific activity of 2040 units/mg of protein was obtained from 1 g of original lung cancer tissue. This inhibitor inhibited trypsin(More)
