The etiology and pathogenesis of lumbar disc herniation is not clearly proved although biochemical change, physical stress, genetic factor, autoimmune phenomenon and psychophysiologic phenomenon have been considered by many investigators. The most important one is a result of pathologic acceleration of normal aging of the tissue. The present study is aimed to investigate the changes of mucosubstances in normal aging and herniated disc which might have possible role on the disc herniation. The materials used in this study consisted of 123 cases of surgically removed herniated disc and 7 cases of normal control disc obtained from autopsy. Sections were cut and stained with periodic acid-schiff (P.A.S.)-alcian blue (pH 2.5) for the detection of neutral mucosubstances, alcian blue at pH 2.5 for nonsulfated acid mucosubstances, and alcian blue at pH 1.0 and Spicers diamine method (HID) for sulfated mucosubstances. The results were as follows. l. Of the 123 cases of lumbar disc herniation, there was a slight male preponderance over female with a ratio of 1.5:1.0. The most commonly affected level was L4-5 comprising 69 cases (56.1%), and up to three quarters of the patients the age was from 3rd to 5th decades in which it was rather evenly distributed. 2. The time interval between the appearance of symptoms and operation was less than 1 year in 77 cases (62.6%), in 32 cases (26.0%) being within 3 months. 3. Histochemical studies of the normal discs showed increase of neutral mucopolysaccharides with reduction of acid and sulfated mucopolysaccharides in the nucleus pulposus, and increase of all the mucosubstances in the annulus fibrosus by aging. 4. Histochemical studies of herniated disc showed an acceleration of the changes seen in normal changes. 5. Cartilaginous end plate formation was noted in 46,3% of herniated discs. The results obtained by the present investigation suggest that herniation of lumbar diosc is closely associated with accelerated or premature degeneration of the disc.

The purpose of this study was to evaluate the rewetting effect of water-based primer on the air-dried dentin. In this in vitro study, freshly extracted non-caries human molars and three-step adhesive system(SBMP) were used. Freshly extracted non-caries human molars and three-step adhesive system(SBMP) were used. Flat occlusal dentin surface were prepared using low-speed diamond saw. Prepared teeth were randomly divided into three groups. Group 1.(W); etched(35% phosphoric acid for 15s) and blot-dried, Group 2.(5D); 5s air-dried, Group 3.(30D); 30s air-dried. To obtain color contrast in CLSM observation, primer was mixed with rhodamine B and bonding resin was mixed with fluorescein. Microscopic sample of each group were obtained after longitudinal section. Morphological investigation of resin-dentin interface and thickness of hybrid layer measurement using CLSM were done. Microtensile bond strength for each specimen was measured. Specimen were observed under microscope to examine the failure patterns of interface between resin and dentin. The results of this study were as follows: 1. The results(mean) of Thickness of hybrid layer were W;19.67, 5D;20.9, 30D;10microm. Only 30D had statistically significant differences to W and 5D(P<0.05). 2. The results(mean) of Microtensile bond strength were W;16.02, 5D;14.69, 30D;11.14MPa. Only 30D had statistically significant differences to W and 5D(P<0.05). 3. There were positive correlation between Thickness of hybrid layer and microtensile bond strength(P<0.05).

To investigate the liver diseases affecting infancy and Childhood and to make a clinicopathologic correlation, a total of 105 liver biopsies were examined and following results were obtained. 1. Of the 105 liver biopsies, 94 cases were available for the study, and the male to female ratio of liver biopsies in infancy and childhood was 1.8 : 1. 2. Of the 94 available cases, 36 were of diffuse hepatitis, 15 congenital biliary atresia, 4 liver cirrhosis and 3 were of malignant neoplasm. The liver biopsy showed only fatty metamorphosis in 12 cases(12.8%) and the remainings were of other rare liver diseases(19.1%) or of normal liver tissue(6.4%). 3. Diffuse hepatitis affected male 2.3 times more commonly than female, and comprised of 3 acute viral hepatitis, 3 chronic active hepatitis, 7 chronic persistent hepatitis, 1 cholangitis, 8 neonatal hepatitis and 14 nonspecific reactive hepatitis. 4. Congenital biliary atresia affected male and female in about equal frequency, and 13 of the 15 cases were extrahepatic. 5. Two of the 4 live cirrhosis were macronodular, and primary and 2ndary cirrhosis were encountered one in each. 6. Of the 12 cases of fatty metamorphosis, 8 were regarded clinically as Reye's syndrome. 7. Among 34 cases in which the serum HBsAg was tested, 11 were positive, namely all of 3 acut viral hepatitis, 2 chronic active hepatitis, 4 chronic persistent hepatitis and all of 2 macronodular cirrhosis. In neonatal hepatitis and congenital biliary atresia it was exclusively negative. 8. The clinical diagnosis was compatible with the biopsy diagnosis in 60.6% of 94 cases.

Among the primary carcinoma of the extrahepatic bile duct, papillary carcinoma is the least common form and usually located in the distal common bile duct. The cholangiographic findings of the papillary carcinoma is similar to translucency produced by stone. We report a case of multiple papillary adenocarcinoma of the extrahepatic bile duct of which the cholangiographic findings mimicking stones.

There is growing evidence that oxygen-derived free radicals(OFR's) play a role in the pathogenesis of pancreatic diseases, especially of acute pancreatitis. Many types of experimental ex vivo and in vitro pancreatitis can be inhibited by superoxide dismutase and catalse. (continue...)

Congenital pancreatic duct anomalies result from an error in the complex developmental process. Congenital pancreatic duct anomalies may be categorized by their mechanisms into migration anomaly, fusion anomaly, and duplication anomaly. These ductal abnormalities have been implicated to be potential causes for both acute and chronic pancreatitis. We have recently observed a congenital anomaly of the pancreatic ducts in which bifurcated main pancreatic ducts drain through the major papilla in a 10 year-old boy presenting with recurrent acute pancreatitis. Although its causal relationship with acute pancreatitis is unclear, this kind of pancreatic ductal anomaly has not been found in the literature.

Papillary stenosis is characterized by fixed fibrosis leading to structural outflow obstruction and it is usually secondary to inflammation and fibrosis from the chronic passage of gallstones, episodes of acute pancreatitis, chronic pancreatitis, sclerosing cholangitis, peptic ulcer disease, and cholesterolosis. However, obstructive jaundice with or without acute cholangitis which leads the physician to suspect the presence of malignancy as a cause is a rare manifestation of papillary stenosis. We report here a case of papillary stenosis presenting with obstructive jaundice and acute cholangitis. The lesion was so difficult to exclude the presence of malignancy preoperatively and intraoperatively that a pylorus-preserving pancreaticoduodenectomy was performed. Histologic examination of the resected specimen revealed fibrosis, adenomatoid ductal hyperplasia, and mild chronic inflammation of the papilla of Vater and distal common bile duct.
