| Title Alternative | Causes and Prevention of Intestinal Adhesions Part 1. Surve of the Literature |

| Author | Ohtani, Mitsuru| |
| Abstract | 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. |

| Title Alternative | The Geochemistry of Rocks from Asama Volcano, Japan. New Approaches in the Quantitative Interpretation of the Chemical Composition of Volcanic Rocks |
| FullText URL | pitsr_032_001_085.pdf |
| Author | Matsui, Yoshito| |
| Abstract | 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. |

| Abstract | 東郷鉱山,方面･麻畑ウラン鉱床の基盤岩および母岩は粘土化が著しく,その特徴として次のことが挙げられる. (a)粘土鉱物の種類,存在量は,鉱床の酸化帯･非酸化帯にはゞ規制されている.(b)粘土化の程度は原岩の種類により異なり,同一種数の岩石では酸化帯における変質が特に顕著である.(c)粘土量とウラン含有量との間には明確な相関は見出せないが,モンモリロナイトの量についてのみ観察すると,おおよそ負の相関がみられる.また,粘土化の主体をなすモンモリロナイトは,結晶度が良好で熱水変質が示唆きれる.化学分析の結果,SiO(2)の量が少ないので珪ばん比が異常に小さいが,ウラン鉱床近辺においてモンモリロナイト化に伴なう珪化帯が認められず,珪酸の逸脱が考えられる.鉱量的にみて,両鉱床の主体をなすウラン鉱物が燐顧塩鉱物であり,珪酸塩鉱物が少ないことなどから,モンモリロナイト化作用と鉱化作用との間には,直接関連がないものと考察される. |

| Title Alternative | The effect of radioactive thermal bathing upon catecholamines of the whole brain of male mice |
| FullText URL | pitsr_045_007_010.pdf |
| Author | Ito, Keiko| |
| Abstract | The author studied the changes of catecholamine levels of the whole brain of male mice weighing 15-20g before and after a single bathing for 20 minutes, 37±1℃ in temperature, in the radioactive hot spring in Misasa (Rn content : 74.83×10(-10)C/l), and compared the results obtained with those of the plain hot water bathing. The catecholamines (dopamine and noradrenaline) were measured by gaschromatographic method using electrone capture detector. It may be summarized as follows : 1. No significant change of dopamine and noradrenaline levels of the whole brain of mice was recognized before and after the plain hot water bathing used as a control. 2. Noradrenaline levels of the whole brain of mice had increased following the radioactive hot spring bath, and remained at same levels for 30 minutes after bathing. Dopamine levels had no change immediately after bathing, but had lowered at 30 minutes from the time of the bath. 3. Causes of these results are under investigation. |

| Title Alternative | Hydrogen and oxygen isotopic ratios of thermal and mineral springs in Arima area |
| FullText URL | pitsr_043_015_028.pdf |
| Author | Matsubaya, Osamu| Sakai, Hitoshi| Tsurumaki, Michiji| |
| Abstract | Saline waters of thermal and mineral springs in Arima area, at Takarazuka, and in Ishibotoke area of Kawachinagano City indicate wide ranges of δD and δ(18)O values (Table 1). Excellent linearity exists between the δD and δ(18)O values (Fig. 1) and between the δ(18)O value and the chloride concentration (Fig. 2). These facts as well as the chemical evidence of the previous investigators strongly support the view that Arima springs are admixtures of a single deep brine and local ground water (TSURUMAKI, 1964). The deep brine may have the δ(18)O value of +8.0～+8.5‰, the δD value of -25～-30‰, and the chloride concentration of 1.20～1.25 eq/l, which were estimated from the water of the maximum salinity so far reported. Because the thermal and mineral springs in Arima area closely associate with the upper Cretaceous granitic rocks, and the estimated δ(18)O value of the deep brine is similar to a value of water in isotopic equilibrium with those granitic rocks at 500～600℃, the deep brine of Arima might have been the magmatic water of those granitic rocks. The mineral springs at Takarazuka and in Ishibotoke area also show the similar linearity among Cl(-), δ(18)O and δD to those in Arima area. Therefore it is assumed that the mineral springs at Takarazuka may be of the same origin as that in Arima area, and the mineral springs in Ishibotoke area might have been the fluid associated with Ryoke metamorphic rocks. Alternatively, the deep brine in Arima area may be isotopically and chemically similar to the saline formation waters in Illinois basin (GRAF et al., 1966). The high δD values and salinities of those formation waters were attributed to the isotopic and chemical fractionation during the passage of water through sediments. The deep brine in Arima area may be genetically similar to those saline formation waters. If such a saline water could have formed in Osaka basin, it is not surprising to find out the similar brines at Arima and Ishibotoke which are the northwestern and southeastern rims of the basin, respectively. At the present, it cannot be answered which of these two models is more probable. Further studies on other saline springs fluid inclusions of Cretaceous granitic rocks may be useful in order to solve this problem. |

| Title Alternative | Fundamental study of post operative intestinal adhesion -Findings on early stage of peritoneal inflammation by ultraviolet irradiation- |
| FullText URL | pitser_046_001_009.pdf |
| Author | Noishiki, Yasuharu| |
| Abstract | Early process of peritoneal inflammation on rat by ultraviolet irradiation was studied histologically and scanning electron microscopic· ally. After 1 minute irradiation of ultraviolet, minimal exudation on mesothelium was found. After 15 minutes irradiation, microvillies on mesothelium were covered with exudate. After 20 minutes, fibrin fibers appeared on intact mesothelium. Though the fibers wafted in exudate, the fibers could be cleared up by irrigation of saline. After 30 minutes, white and red cells appeared on the nest of fibrin fibers. After 45 minutes, edema came out at subserosal layer. After 1 hour, mesothelium was covered with fibrin fibers, white and red cells. But the coated fur could be washed off by jet irrigation of saline and intact mesothelium benearth the fur appeared. These results indicate that washing a peritoneal cavity by saline after abdominal operation is of practical value to prevent a intestinal adhesion due to post operative intestinal inflammation. Inflammatory changes of intestinal mesothlium was clearly demonstrated by scanning electron microscope and these observations revealed that scanning electron microscope was very useful for the study of inflammation which occured on the surfaces of organs. |

| Title Alternative | Stable isotope study of the hotsprings and volcanoes of Hokkaido, Japan |
| FullText URL | pitsr_047_055_067.pdf |
| Author | Matsubaya, Osamu| Sakai, Hitoshi| Ueda, Akira| Tsutsumi, Makoto| Kusakabe, Minoru| Sasaki, Akira| |
| Abstract | Stable isotope ratios of hydrogen, oxygen, carbon and sulfur of precipitation, thermal and mineral waters, and volcanic gases were measured. The isotopic data combined with chemical and geological information were discussed in terms of origin and evolution of the hotsprings and volcanic gases. The hotsprings along the Uchiura Bay, Oshima Peninsula are mostly near-neutral NaCl-type thermal water and may be divided into three groups : (1) thermal waters isotopically similar to the precipitation of this area, (2) those similar in D/H to the local meteoric waters but enriched by 2 to 3‰ in (18)O compared to the latter, and (3) those enriched significantly in both D and (18)O relative to the local meteoric waters. The first and second types of thermal water probably form from local meteoric water which percolates through "Green Tuff" formations and acquires dissolved chemicals from them. However, high salt concentration and the oxygen isotope shift (thesecond type) may imply that the NaCl-type water of volcanic origin might be involved. On the other hand, the waters of the third group can be explained by mixing of modern sea water into the second type thermal water (in case of Yachigashira) or by incorporation of fossil sea water of Tertiary origin into modern meteoric water (Nigorigawa). Except for Esan, Noboribetsu and Atosanupuri volcanic systems, waters from all the hotsprings and volcanic fumaroles associated with Quaternary volcanic rocks are meteoric in origin. Thermal waters at Esan, Noboribetsu and Atosanupuri have δD = -30～-50 and δ(18)O = -1～+ 3‰ and are enriched in D and (18)O relative to local meteoric water of the respective area. The origin of these waters and the mechanism (s) controlling the isotope ratios could not be made clear by the present study. Interesting is the finding that at Esan, Noboribetsu and Atosanupuri, thermal waters are enriched in D and (18)O relative to near-by fumarolic gases. The enrichment factor is 18 to 26‰ for hydrogen and 4 to 6‰ for oxygen, implying that more than one stages of liquidvapor separation are taking place in underground hydrothermal systems. |
