抄録 Neo-Thorin was previously presented by the other authers as a color-developing reagent for the spectrophotometric determination of zirconium. 1) To determine the optimum condition for the use of this method, the effects of pH, time and temperature, and the interference of several ions were checked. The following conclusions were derived from the experimental results: Absorption curve-- The zirconium Neo-Thorin complex salt shows a maximum absorption at 580 mμ against Neo-Thorin (Figs. 1 and 2). Effect of pH-- The complex salt gives a maximum absorption at pH 1. 7 (Fig. 3). Effect of time and temperature-- Color absorption is stable for a period of 15 to 200 minutes after color development at room temperature. Heating over 40°C is harmful, because of the formation of a purple precipitation. Interference by several ions-- Cations UO(2)(2+) and Fe(3+) besides Th(4+), considerably interfer with color development. The absorption of 2000 μg U corresponds to that of 10 μg Zr (Fig. 4). However, interference by Fe(3+) becomes negligible if hydroxylamine hydrochloride is added. 2) As a result of the above conclusions, the following procedure is recommended: Procedure recommended-- A few ml of sample solution, 1 ml of 20% hydroxylamine hydrochloride and 1 ml of dilute acid, if necessary, are mixed and diluted to 9 ml. To this solution, 1 ml of 0.05% Neo-Thorin is added. The pH value of the final solution is 1.7. From 15 to 200 minutes after mixing, color absorption is measured at 575 mμ. In the range of 0 to 150 μg Zr per 10 ml, the color absorption of the complex salt obeys Beer's law (Fig. 5). 3) In demonstration, this method was applied to the determination of zirconium in a uranium mineral. Table 1 shows the zirconium content of beta-uranophane from Katamo Mine, Tottori-ken.

抄録 In order to investigate the frequency of postgastrectomy syndrome in patients with benign gastroduodenal diseases who gastrectomized partially, the authors studied the case records of consecutive 100 such patients treated at this institute. The results obtained were as follows. 1) Concerning postoperative diagnosis, 55 patients were diagnosed as ulcus ventriculi; 22, ulcus duodeni; 4, ulcus vent. et duodeni; 10, gastric hyperacidity only; 4, perigastric adhesion; 2, ptosis ventriculi; 2, gastric polyp; 1, duodenal diverticulum. 85 patients were male; 15, female. Concerning operative method, 21 patients were operated on Billroth I procedure; 19, Billroth II antecolica oralis inferior with Braun's anastomosis; 60, Billroth II oralis inferior. 2) Of 28 patients with postgastrectomy syndrome, 9 patients had early postprandial syndrome; 6, late postprandial syndrome; 6, postoperative gastric atonia; 2, afferent loop syndrome; 1, obstruction of efferent loop; 2, intestinal adhesion; 2, ulcer of anastomosed site. 3) In our series, there were no significant difference in frequency of postgastrectomy syndrome between B. I and B. II procedure, but postgastrectomy syndrome of patients with B. II were more severe than that of patients with B. I. 4) Of 72 patients without postgastrectomy syndrome, 69,7% (50 patients) continued to gain weight postoperatively, but of 28 patients with postgastreetomy syndrome 28,5% (8 patients) gained weight postoperatively.

タイトル(別表記) Causes and Prevention of Intestinal Adhesions Part 2. Experimental Study of Intestinal Adhesions
フルテキストURL pitsr_031_054_074.pdf
著者 大谷 満|
抄録 The experiments were designed (1) to investigate the effects of various types of injury to the peritoneum on the formation of adhesions, and (2) to study the hitological changes of the intestinal wall when injured artificially with 5 % iodine tincture. The experimental animals used were Wistar adult male rats with a weight range of 90 to 120 grams. A total of 170 rats were used. Experiment 1. The experimental animals were divided into 10 groups, each group consisting of 10 to 20 rats. Group A. The caecal serosa was injured with 2 % iodine tincture. Group B. The caecal seroSa was injured with 5 % iodine tincture. Group C. The caecal serosa was abraded with gauze until subserosal petechies were produced. Additional trauma to this area waS inflicted with 2 % iodine tincture. Group D. The caecal serosa was injured as in group C, but 5 % iodine tincture was used. Group E. The caecal serosa waS injured with 2 % aqueous mercurochrome solution. Group F. The caecal serosa was rubbed with gauze until subserosaI petechies were produced. Additional trauma to this area was inflicted with 2 % aqueous mercurochrome solution. Group G. The caecal wall was rubbed with gauze 100 times, injuring the subserosa. Group R. The anterior wall of the stomach and caecum was traumatized with a toothbrush and 2 ml of aqueous talcum solution were instilled into the peritoneal cavity. Group I. Excisions of the parietal peritoneum were performed with a surgical knife over areas of varying sizes at both sides of the operation wound. Group J. Adjacent loop of the intestines with normal serosa were connected to one another by No.2 black silk suture at two or three points. In five cases of this group, contacting surfaces of the intestines were injured with 5 % iodine tincture. The results obtained were as follows : (1) Local administration of 2 % iodine tincture and 2 % aqueous mercurochrome solution would not produce adhesions unless mechanical injury, such as rubbing with gauze was also present. (2) When the serosa was slightly injured with gauze, fibrinous adhesions were separated or torn apart by bowel movements. (3) Local administration of 5 % iodine tincture produced in all members of group B. The adhesions were moderate, not extensive in degree. Additional mechanical trauma aggravated the adhesions caused by bacterial contamination. (4) Intraperitoneal instillation of 10 % aqueous talcum solution produced extensive adhesions. The favorite sites of occurrence of the adhesions were the greater omentum and the small intestine. (5) Excision of the parietal peritoneum over areas of vareous sizes caused no adhesion. (6) Even prolonged contact between the intestinal wall and normal serosa did not result in the formation of adhesions. However, firm adhesions resulted from prolonged contact between injured serosal surfaces regardless of the type of injury. (7) The author would like to emphasize that large peritoneal defects should be left untreated, because attempts at peritonealization result in additional injury to the subserosa and often in more extensive adhesions. Experiment 2. (1) Edema and an infiltration of leucocytes occurred in the early stages of the inflammation. These histological changes were seen not only in the subserosa, the muscular layer, and the submucosa, but also in the mucosa. Lesions in the mucosa slowly developed into necroses or ulcers. The intensity of the adhesions varied with the severity of the lesions in the mucosa. (2) Twenty-four hours after injury to the peritoneum, P. A. S. positive substances began to appear in the submucosa, disappearing fourth post-operative day. (3) The process of the formation of the adhesions may be outlined as follow: a) After injury to the peritoneal surface, an exudate is formed. b) Thise xudate coagulates to form fibrin, which causes adiacent surfaces to cohere. c) Dunng organization, fibroblasts or fibrocytes migrate into this area. e) Whth the aid of mucopolysacchrides in ground substances, collagen is deposited and grdually a firm adhesion is formed. In some cases, however, this area becomes membraneous or strand-like in form during the completion of the process of adhesions, and is eventually torn apart.

タイトル(別表記) Causes and Prevention of Intestinal Adhesions Part 1. Surve of the Literature
フルテキストURL pitsr_031_040_053.pdf
著者 大谷 満|
抄録 1) Seven types of irritation causing intestinal adhesions are recognized in the literature : namely, a) mechanical injury; b) chemical injury; c) thermal injury; d) bacterial infection; e) foreign body; f) blood; and g) exsiccation. Certain minor differences of opinion exist among investigators, according to the experimental methods and the experimental animals used, and blood is not universally accepted as a cause of adhesions. The author believes, however, that the above list includes all of the etiological factors so far recognized in the literature. 2) The mechanism of intestinal adhesions is similar to that of wound healing. The problem of fibre synthesis is still unsolved, despite many advances in electlon microscopy, histochemistory and X-ray analysis. In recent years it has been accepted that fibres are synthesized in extra-cellular space from cytoplasmic materials derived from either mesenchymal cells or fibroblasts, and from polysaccharides in ground substances, althoughth eexact kind of polysaccharides which plays an important role in this process is still unknown. 3) Many papers are recognized with the prevention and treament of adhesions. These may be devided into six groups according to the method suggested: a) limitation of the original peritoneal injury; b) prevention of the coagulation of the exudate; c) avoidance of prolonged contact between the injured surfaces; d) removal of the fibrin after its formation; e) stopping or slowing down of the proliferation of fibroblasts; f) prevention of further obstruction by means of controlling the area of damaged intestine in stepladder fashion, the so-called the plication method. 1. It is the common practice of surgeons to limit the original peritoneal lllJury by laparotomy. Experimental studies have demonstrated that peritonealization of an area denuded of serosa often results in more extensive adhesions. 2. To prevent coagulation of the exudate, Lehman and Boys and other investigators used heparin and dicumarol. The role of heparin in the prevention of adhesions may be summarized as follow: there is a short time interval separating the production of the exudate and its subsequent coagulation with the deposition of fibrin on injured serosal surfaces. Anticoagulants of various types should be effective in preventing this fibrin formation if it is assumed that the coagulation mechanism of both exudate and blood is the same. Though the use of heparin and dicumarol has demonstrated a preventive effect on adhesion formation in experimental animals, many surgeons believe that the risk of hemorrhage from heparin and dicumarol outweighs their possible benefit in the prevention of adhesions. 3. To prevent prolonged contact between injured surfaces, amnion, omental and mesothelial graft, and so on, have been used without success. The stimulation of peristalsis by means of prostigmin and early feeding, however, appears to be effective in the prevention of adhesions, although its use in clinical cases has not been reported. 4. The experimental data indicates that streptokinase alone has no preventive effect on the formation of adhesions, because fibrinolysis is facilitated only by the existence of activated human plasmin. Concernig the use of hyaluronidase, this is an enzyme with the property of hydrolyzing hyaluronic acid, one of the polysaccharides that constitutes the intercellular ground substances. Experimental studies on the use of this material indicate, in summary, that topically administered hyaluronidase reduces the number of adhesions and particularly their density. The reason why hyaluronidase is effective in the prevention of adhesions is still unknown. 5. The use of corticoids and ACTH, according to all available experimental data, appears to delay the formation of adhesions and to prevent talc-induced adhesions, possibly by increasing the absorption of talc. In administrating corticoids, however, their tendency to delay wound healing, to perforate the intestinal wall, and to induce hemorrhage must be taken into account. 6. Experimental study and clinical USe of the plication method demonstrate that in patients with severe recurrent adhesions, or in those for whom the afore-mentio ned methods have been ineffective, this procedure is probably the most effective therapy available.

タイトル(別表記) Electrcardiographic Changes in Rheumatoid Arthritis: Part 2. Frequency of Electrocardiographic Changes in Rheumatoid Arthritis and Other Diseases
フルテキストURL pitsr_031_031_039.pdf
著者 北山 稔|
抄録 As reported in Part 1 of this paper, the author observed a variety of electrocardiographic aberrations in 27 patients with rheumatoid arthritis. This report will compare the frequency of electrocardiographic aberrations in 45 such cases with the frequencies shown by other groups, namely : a group of 122 patients with normal blood pressure and noncardiac diseases, a group of 121 patients with hypertension, and a group of 14 patients with mitral valve diseases. The results are as follows : 1) The electrocardiographic patterns reported in Part 1 occurred more frequently in both the group of rheumatoid arthritis patients and the groups of hypertension and mitral valve disease patients than in the group with normal blood pressure and noncardiac diseases. 2) On the basis of the electrocardiographic findings, it may be assumed that many of the patients with rheumatoid arthritis suffered from pathological heart conditions, such as heart diseases or cardiac involvement, not accessible to clinical observation. 3) Patients with unequivocal cardiac involvement constituted 21 (46.6%) of the rheumatoid arthritis patients, 65 (53.7%) of the hypertension patients, 9 (64.3%) of the mitral valve didease patients, and 21 (17.2%) of the normal blood pressure and noncardiac disease patients. 4) Patients with suspected cardiac involvement, as defined in Part 1 of this paper constituted 4 (8.9%) of the rheumatoid arthritis patients, 10 (8.3%) of the hypertension patients, 1 (7.1%) of the mitral valve disease patients and 2 (1.6%) of the normal blood pressure and noncardiac disease patients.

タイトル(別表記) Electrcardiographic Changes in Rheumatoid Arthritis: Part 1. Relationship between Electrocardiographic and Clinical Findings
フルテキストURL 031_010_030.pdf
著者 北山 稔|
抄録 The author studied the relationship between electrocardiographic and clinical findings in 27 patients with classical rheumatoid arthritis, as defined by the criteria for the diagnosis of rheumatoid arthritis proposed by the American Rheumatism Association. The results obtained were as follows: 1) In 26 of the cases, such electrocardiographic aberrations were observed as the following: broad P waves; mitral P-like patterns (either double peaked or with the mean P vector veering to the left in the frontal plane) ; prolongation of the P-Q interval; high amplitude of R in the left precordial lead; elevation or depression of S-T segments; low or flat T waves in the left precodial lead; prolongation of QTc ; and changes of directions of mean QRS and T vectors to the left in the frontal plane. 2) The frequecies of plainly pathologic findings were as follows: prolonged P-Q interval - 1 case (3.7%) ; RV5≧30mm - 3 cases (11.1%) ; elevation of S-T segment - 1 case (3.7%) ; depression of S-T segment - 3 cases (11.1%) ; and prolongation of QTc - 9 cases (33.3%). 3) Pathologic cardiac involvement was found in 13 patients (48.2% of the total group) while 3 other patients were classified as suspected cardiac involvement cases, defined as those characterized by more than three abnormal but non-pathologic findings. 4) Thus, the majority of the test group were characterized by some abnormal or pathologic electrocardiographic finddings, although clinically no heart diseases or cardiac insufficiency had been detected.

抄録 Following Ueda-Yasuda's Procedure, the author observed changes on the portal blood circulation time, the body temperature, the blood pressue and the pulse rate of 16 patients (A group, five patients with caecum mobile or appendicitis chronica : B group, six patients with appendicitis acuta non-perforativa : C group, five patients with appendicitis acuta perforativa = appendicular peritonitis). Measurements were taken four or five times: before operation, immediately after operation, on the first, third, and fifth, postoperative day. Portal blood circulation time before operation was significantly prolonged in C and B group as compared with A group. Portal blood circulation time immediately after operation was prolonged in each group as compared with that taken before operation. Postoperative duration of prolonged portal blood circulation time was longer in C group more than in A and B group. Postoperative courses of all 16 patients were good and without postoperative complications.

抄録 Following Ueda-Yasuda's procedure, the author observed changes on the portal blood circulation time, the blood pressure and the pulse rate of five normal men following a cold bath in water. Measurements were taken three times 30 minutes before the bath, immediately after the bath and 30 minutes after the bath (the bath was either 5 or 10 minutes in duration, and ranged in temperature from 26°to 28℃). Portal blood circulation time immediately after a 10 minute cold bath was found to be probably shortened as compared with that taken before the cold bath. The changes in blood pressure and pulse rate observed after the cold bathing were similar to those reported by other authors.

タイトル(別表記) The Geochemistry of Rocks from Asama Volcano, Japan. New Approaches in the Quantitative Interpretation of the Chemical Composition of Volcanic Rocks
フルテキストURL pitsr_032_001_085.pdf
著者 松井 義人|
抄録 In dealing with the geochemistry of volcanic rocks, it appears imperative, first, to refine the procedure of rock analysis with respect to both major and minor components, and second, to improve present methods of interpreting analytical data on common rock suites such as basalts, andesites and dacites. In regard to the first problem, the rapid method of silicate analysis as described by Shapiro and Brannock (1956) and by Riley (1958) deserves special attention. With such a method it is possible to estimate the accuracy and precision of data with far greater ease than is possible with a classical one, yet without any loss of quality. For the determination of some components, however, it is felt that the procedures recommended previously lack precision and/or simplicity. In Part I of this paper, new methods are suggested for these components. The sum of Mg, Ca and Mn is titrated with EDTA in the presence of Al, Fe and other metals, using thymolphthalein complexone as indicator at pH 10-10.5. The sum of Al and Fe is determined by the back-titration of excess EDTA with the standard Cu solution. PAN is used as indicator at pH about 4, and tartrate is added as the masking agent of Ti. Na and K are determined by flame photometry using very dilute solutions (1-5ppm Na or K), without the separation of other metals and without the use of the internal standard. Sr is included in the scheme of analysis, and is determined by flame photometry according to the standard addition technique. These procedures are tested for their accuracy using the standard samples G-1 and W-1 (Tables 3, 5, 9, 12 and 15). Procedures for other components are also described in the text in full detail. The system of analytical procedures recommended is shown in Table 16. To investigate the problem of the interpretation of compositional variation, typical rocks from Asama volcano and the surrounding area were selected, namely, andesites and dacites of calc-alkaline type. Twenty-one samples, described in Tables 18 and 19, are analyzed according to the above procedures. Results are shown in Table 20. Variation diagrams are presented in Figs. 3 to 5. Since it may be questioned whether the "trend" seen in the diagrams implies a genetic relationship, a least squares approximation technique has been introduced in order to determine whether the composition of the main components of a rock (F) can be expressed by the linear combination of a selected set of compositions of a magma and the phenocrysts crystallized from it : F(o)=F(1)x(1)+F(2)x(2)+······+F(m)x(m) ······(1) where F(1), F(2), ... denote the compositions of a magma and minerals, and F(o) is the calculated composition of F. These calculations lead to the conclusion that there are at least two series of rocks in Asama (Tables 25 to 30 and Fig. 9), distinguished from each other mainly by their K(2)O content. Those rocks showing features of assimilation (Aramaki, 1963) all belong to the K(2)O-rich series. Contents of minor components such as TiO(2), MnO, P(2)O(5) and SrO are analyzed by the linear regression technique in two ways, for example : TiO(2)(o)=C(1)x(1)+C(2)x(2)+ ······(2) and TiO(2)(o)=aMgO+bFe(o) +cK(2)O ······(3) These methods are found useful in discriminating rocks of different ongm and in distinguishing the characteristic behavior of each component. Results of calculations (Tables 31 to 34) support the conclusion reached by calculations based on the contents of major components.
