We investigate the activity of deep low-frequency earthquakes (DLE) in Japanese Islands by JMA hypocenter catalogue during 1997 to 2008. It is confirmed that DLE cluster is distributed in every region. This implies that DLE phenomenon is common in Japanese subduction zone. Many active DLE clusters are identified in and around the quaternary volcanoes in whole area. There are also many non-volcanic clusters in Hokkaido and Tohoku regions, but very few in Kanto, Koushinetsu, Chubu, Hokuriku and Kyushu regions. High activity of non-volcanic clusters is observed in Kinki region. No clear correlation between DLE number and volcano activity index during 100 and 10,000 years is recognized. This fact implies the possibility that DLE activity is not precursor signal of shallow volcanic activities such as eruption at any time. Lower limit of DLE hypocenter depth generally coincides with depth of Moho discontinuity of each region. This may indicates that structure of upper mantle and lower crust and its boundary strongly control the occurrence of DLE's.

Some etiological studies of gall stones and of cholecystitis have ever been made and discussed from various angles and now it is apparent that the infection of the bile ducts plays important roles etiologically for them, aside from the problem whether it is concerned with them primarily or secondarily. But the infection theory contains some contradiction which is pointed out by various researchers in the fact that even many ba-cteria instillated into the gall bladder do not cause the formation of gall stones or cholelithiasis so easily.On the other, Prof. Matsukura has ever noticed the fact that in cholelithiasis and cholecystitis the concentration of bile acids, particularly of dihydroxycholanic acid, is conspicuously lowered in comparison with that of normal cases and advocated the significance of the low concentration of dihydroxycholanic acid in the infection of the bile ducts, based upon various clinical and experimental studies made in his laboratory.The author made some serial clinical and experimental studies on bile acids in bile, particularly the significance of the substance “Dihydroxycholanic Acid” in the infection of bile ducts, as one part of the etiological studies of cholecystitis and gall stones undertaken in the laboratory and obtained some results as follows.1) The concentration of dihydroxycholanic acid in bile of healthy person or of patients with gastroduodenal ulcers is high, ranging from 30 to 60 mg/cc, while in cholelithiasis and cholecystitis, the levels are mostly in a range less than 20 mg/cc.2) No bacteria were detected in the bile of healthy person or of the patients with gastroduodenal ulcer. But in bile of cholelithiasis or of cholecystitis, showing the level of dihydroxycholanic acid in a range less than 20 mg/cc, bacteria were found and isolated.3) Coli-bacilli occupied the majority among the microorganisms isolated from the bile of cholelithiasis and of cholecystitis.According to these clinical and experimental studies, it can be presumed that in cholecystitis and in cholelithiasis, the colibacilli played the cardinal role and the infection of the bile ducts with coli-bacilli is closely related with the lowering of the concentration of dihydroxycholanic acid in bile.The author made a experimental study regarding the relation between the lowering of the concentration of the acid and the infection of the bile ducts in rabbit and following results were obtained.4) The level of the dihydroxycholanic acid in the normal rabbit ranged from 70 to 110 mg/cc but if the occlusion of the bile ducts was artificially made at the Vater's ampullae where the choledochus joins the duodenun, the level increased slightly on the 2nd postoperative day but then decreased gradually up to the levels of 12 to 32 mg/cc on the 8th day, showing apparently the lowering tendency.5) In normal rabbits which accepted colibacilli through the portal vein and in the group of rabbits of which liver function was damaged with carbon tetrachloride and 2, 4-diaminotoluene, coli-bacilli were detected in both of the groups but the numbers of the bacilli were markedly small and the slight increase of the bacilli was observed only in one case out of those with damage of the liver function. But in all of ten cases with the occlusion of the bile ducts, a great number of bacilli were observed. Moreover, in 8 cases, gall stones were constituted and in 2 cases bile sands were seen.6) 1. In liver of normal rabbits which were instillated coli-bacilli through the portal vein, very slight inflammatory changes were seen, but at the gall bladder no inflammatory changes were seen grossly as well as histologically.2. In livers of rabbits as well as in the gall bladder, with the damaged liver function and instillation of coli-bacilli through the portal vein, almost no inflammatory change was observed in the gall bladder.

At laparatomy of surgical disease in the upper abdomen, the specimens were collected from the gall bladder, common bile duct, duodenum, jejunum, ileum and trnsverse colon. From each of specimens, E. coli was isolated and O-serotypes were identified, and thus the ecology and physiopathology of E. cole in human intestine were examined.1) The examination of the biliary system, E. coli was detected in choledocholithiasis with the highest percentage (50%) and cholecystolithiasis (15%), and stomach cancer (9%) were followed. No E. coli was found in ulcer froup.2) In the duodenum and jejunum, the incidence of E. coli was the highest in the froup of choledocholithiasis (50%, 50%), followed by stomach cancer (29%, 32%), cholecystolithiasis (15%, 18%) and ulcer (5%, 4%).3) In the terminal ileum, the detection rate was conciderably high in the following three groups: stomach cancer (72%), cholecystolithiasis (64%), choledocholithiasis (63%). On the contrary, ulcer group showed the lowest rate of 30%.4) The group E. coli was found in the terminal ileum was associated with some other pathologic conditions than the group E. coli was found in the transverse colon only.5) In the case E. coli was found in the upper digestive tracts above jejunum including the biliary system, this organism was found in the whole intestinal tracts as predominant resident, and only one species was found as a rule. In the group E.coli was detected only in the transverse colon, three serothpes were identified.6) The serothpes from 0-1 to 0-25 and so called toxic E. coli were mostly detected in the upper digestive tracts. However, no this type of phenomomen was observed in the enteropathogenic E. coli.

From the point of allergy, the authors studied on the production of cholelithiasis and cholecy-stitis and the results obtained were as follows: 1. By agglutination reaction with the antigen of E. coli (O-6) isolated from human faeces and the normal human serum, it was found that the aggulutin in titer was so low in the infant and the titer rising up rapidly with the age to 10 years old. Thereafter the titer is coming close gradually to that of the adult. These facts suggest that tha natural sensitization by E. coli exists in the human being and it may be strengthened gradually with the age. 2. Natural sensitization by E. coli was also found in the normal rabbit and it was also observed that the natural sensitization was enphasized by the oral administration of E. coli. 3. The disturbance of the liber may produce dysbacteria of the intestinal flora and the dysbacterial condition of the intestinal flora and the disturbance of the liber-function may emphasize the natural sensitization by oral administration of E. Coli and moreover it may be an important factor in the appearance of orally administered E. Coli in the bile. 4. The bile of gastro-ulcer showihg no precipitation reaction with anti-E. Coli rabbit serum was mixed with E. Coli (O-6) and after 24 hours' incubation at room temperature the bile showed positive reaction with anti-E. Coli rabbit serum. 5. The remarkable growth of E. Coli was found in the group of rabbits blocked the bile-duct injected E. Coli via bile-duct, however no growth of bacilli was observed in the normal rabbits; moreover, the bile in the former cases showed positive reaction with anti-E. Coli rabbit serum. 6. Electromicroscopic findings show that the breaking or dissolution of cell wall or cell membrane and the prolapse of the protoplasma of E. Coli at the high concentration of Desoxycholic acid or glycodesoxycholic acid. 6. The gall-bladder isolated from the guinea pig administered orally E. Coli and showing high aggulutinin titer showed anaphylactic reaction by Schultz-Dale technique. Anaphylactic reaction of the isolated gallbladder in the guinea pig sensitized with anti-E. Coli rabbit was alse demonstrated and also the desensitization phenomenon was clearly demonstrated with the addition of the same antigen. These results suggest that allergic or anaphylactic reaction in the gall-bladder with antigen-antibody system of the components of E. Coli might be existed.

北海道では,軟弱な泥炭地盤が広がり,地震時には宅地や地中管路に被害が出やすい.北海道浦河町にも泥炭が堆積しており,1982年浦河沖地震や2003年十勝沖地震では建物被害だけでなく地中の水道管路にも被害が発生した.本研究では浦河町を対象にして,表面波探査から表層の泥炭地盤のS波速度や深さを推定し,泥炭地盤を有する断面の地震応答解析によって,表層の地盤ひずみを算出した.狭隘な谷筋に堆積した地盤の基盤面が不整形であることだけでなく,泥炭地盤のS波速度や深さが地盤ひずみに大きく影響することが明らかになった.さらに,基盤面の勾配が大きいところで過去の地震における管路被害が多く発生していることが分かった.
