Biochemical method was adopted to examine 10 kinds of histologic enzyme spectrum activities in gastric intestinal metaplasia, carcinoma and normal or superficial gastritis mucosa taken from different sites from 17 fresh surgical specimens of stomach. The enzymes are aldolase (ALD), pyruvate kinase (PYK), phospho hexo-isomerase (PHI), lactic dehydrogenase (LDH), creatine phosphokinase (CPK), hydroxybutyrate dehydrogenase (HBD), glutamic-pyruvic transaminase (GPT), alkaline phosphatase (AKP), acid phosphatase (ACP), r-glutamyl-transpeptidase (gamma-GT). Among glycolytic enzymes the content of ALD, PYK in intestinal metaplasia were 24.5 u and 24.6 u respectively, which were higher than those in the normal mucosa (15.7, 18.0) and lower than carcinoma (28.4, 29.6) (P less than 0.01-0.05). The content of CPK in intestinal metaplasia was lower (218.5 u) than that in the normal (463.9 u) and higher than that in carcinoma (110.3 u) (P less than 0.01). Among protease and amino acid enzymes the content of HBD in intestinal metaplasia was lower (108.2 u) than those in the normal (221.3 u) and carcinoma (113.9 u) (P less than 0.05). The content of GPT in intestinal metaplasia was (6.7 u) which was lower than that in the normal (9.4 u) and higher than that in carcinoma (3.7 u) (P less than 0.01). The above results could provide reference indices for judging the potential malignancy of gastric intestinal metaplasia.

The influence of diazepam treatment following prolonged ethanol administration was toxicologically examined in rhesus monkeys and rats. In the monkey, ethanol was intragastrically administered through a chronically implanted catheter by programmed infusions at doses of 1.5 g/kg 4 times daily every 6 hours over a period of 5 or 10 weeks and followed by intragastric administration of diazepam 4 mg/kg twice a day for 5 weeks. In the rat, ethanol was administered by gavage at doses of 8 g/kg once a day or 4 g/kg twice a day for 5 weeks after which diazepam 300 mg/kg was intragastrically administered once daily for 5 weeks. In the monkey, ethanol produced such toxic changes as hypertriglyceridaemia, fatty metamorphosis of the hepatocytes associated with megamitochondria, proliferation of smooth endoplasmic reticulum and vacuolation in the hepatocytes, and gastritis. Diazepam did not aggravate but mostly alleviated these changes. In the rat, on the contrary, the serum GPT level slightly elevated due to the ethanol administration, and remained at the elevated level with the diazepam treatment in contrast with the complete recovery with non-treatment for 5 weeks after the ethanol administration. However, such changes as increase of fat droplets in the hepatocytes and the triglyceride concentration in the liver which had been developed by ethanol administration recovered during the diazepam treatment period. In spite of the recovery, the elevation of the serum GPT level being remained by diazepam may indicate possible influence of diazepam on the liver function when the drug is administered after prolonged administration of ethanol.

A 48-year-old woman with type II diabetes developed fatigue, arthralgia and myalgia. A few weeks later she was found to have hepatomegaly. The erythrocyte sedimentation rate was raised (53/93 mm), as were liver enzyme activities (GOT 186 U/l; GPT 240 U/l; gamma-GT 199 U/l), the gamma-globulin levels (40.7%;IgG 4470 mg/dl, IgA 698 mg/dl, IgM 245 mg/dl), antinuclear antibodies and antibodies against double-strand DNA, smooth muscles and actin. Laparoscopy revealed small-nodular liver cirrhosis. The autoimmune hepatitis was treated with prednisolone (initially 60 mg daily, then reduced to 10 mg daily) and azathioprine (initially 100 mg daily, reduced to 50 mg daily). The symptoms markedly improved. But one year later, during follow-up examination, gastric polyps were found, excised and histologically found to be carcinoid. The gastrin level was raised to 765 pg/ml. Another year later the liver cirrhosis had advanced further and the type A gastritis was still present, but there was no sign of carcinoid recurrence.

Megaesophagus was diagnosed in 9 adult ferrets. Clinical history of the ferrets included regurgitation, difficulty in swallowing, partial anorexia, and lethargy. Cachexia, dehydration, weakness, and ptyalism were observed on physical examination. Radiography revealed the esophagus of each ferret to be dilated in the thoracic and cervical regions. Of 4 ferrets that had lymphocytopenia, 2 had concurrent leukopenia. Serum biochemical analysis revealed high activity of alanine transaminase (4 ferrets) and aspartate transaminase (3), and hypoglycemia (4). Treatment included administration of fluid, antibiotics, and agents directed against possible primary causes of megaesophagus. Treatments were ineffective, and all of the ferrets died or were euthanatized. All 6 ferrets that were submitted for necropsy had bronchopneumonia, hepatic lipidosis, mild esophagitis, and gastritis. The etiopathogenesis of megaesophagus in the ferrets was not determined.

A 60-year-old man complained of severe general fatigue on October 11, 1992. Pertinent laboratory findings were: aspantate aminotransferase (AST) 1920 IU, alanine aminotransferase (ALT) 2050 IU, and total bilirubin (T. Bil) 124 micromol/l (normal range, 0-17 micromol/l). Virological assay revealed that hepatitis B surface antigen (HBsAg), anti-hepatitis B e (HBe), anti-HBc, and immunoglobulin M (IgM) anti-HBc were positive, and anti-HBs, HBeAg, and anti-delta antibody were negative. A diagnosis of acute hepatitis due to hepatitis B virus was made. Despite a decrease in transaminase, jaundice worsened and prothrombin time was prolonged. On the 60th day of hospitalization, massive ascites developed, but the patient's consciousness was not impaired. Although, albumin and diuretics were given, the ascites further increased. Paracentesis of 2000 ml of ascitic fluid was performed twice a week. On the 120th day of hospitalization, the patient passed black stools and he exhibited renal failure 3 weeks later. Although severe jaundice persisted, he was still alert. On the 150th day of hospitalization, massive gastrointestinal bleeding occurred, due to hemorrhagic gastritis. Despite receiving intensive care, the patient died. Determination of the HBV DNA sequence revealed two point mutations in the pre-core region; these have not been reported elsewhere.

The U.S. Air Force is converting from JP-4 jet fuel to the less volatile JP-8 jet fuel, which is similar to commercial Jet Fuel A. Our previous 90-day inhalation study with JP-8 vapor, using F-344 rats and C57BL/6 mice, resulted in no treatment-related adverse effects other than alpha 2-microglobulin nephropathy in male rats (Mattie et al., 1991). In the present study, male rats were dosed with neat JP-8 (0, 750, 1500, 3000 mg/kg) daily by gavage for 90 days in an effort to characterize the kidney lesion and assess further any additional adverse effects associated with prolonged oral exposure to this fuel. Results of this study revealed a significant dose-dependent decrease in body weights of rats exposed to JP-8. Male rat-specific alpha 2-microglobulin nephropathy was observed by histopathologic examination. A number of significant changes were also seen in blood and urine that were not dose-dependent. Additional treatment-related effects were a gastritis and a perianal dermatitis. Although there were no histopathological or weight changes in the livers of exposed rats, there was an increase in the liver enzymes AST and ALT. The elevated enzymes did not increase with increasing dose of JP-8.

To evaluate the feasibility of adjuvant chemotherapy, we analyzed the toxicities of chemotherapy for primary breast cancer in Japanese women. Since the opening of the National Cancer Center Hospital East, 180 female breast cancer patients have received adjuvant chemotherapy or chemo-hormonal therapy following surgical treatment between June 1992 and December 1995. On the basis of informed consent about prognosis and adjuvant therapy, most patients decided to choose the type of cytotoxic chemotherapy themselves. Adjuvant chemotherapy consisted of oral fluoropyrimidine compounds (OFP), cyclophosphamide + adriamycin +/- 5-fluorouracil [CA(F)] or cyclophosphamide + methotrexate + 5-fluorouracil (CMF). Toxicity was determined using the Toxicity Grading Criteria of the Japan Clinical Oncology Group (JCOG). Sixty-six patients received OFP, 59 CA(F) and the rest 55 CMF. The toxicity grading of leukocytes and neutrophils was significantly higher in patients treated with CA(F) or CMF than in those treated with OFP. Similar results were also seen relating to the toxicity of nausea/vomiting and alopecia. There was no statistical difference in the toxicity grading of hemoglobin, glutamic oxaloacetic transaminase/glutamic pyruvic transaminase (GOT/GPT) and stomatitis/ gastritis between the three groups of patients. Interestingly, the number of patients that were forced to discontinue chemotherapy was higher in those receiving OFP than in those receiving CA(F) or CMF. Cytotoxic chemotherapy of CA(F) or CMF results in greater toxicity than OFP, but is tolerated and feasible in the adjuvant setting used in Japanese breast cancer patients from the viewpoint of toxicities by anticancer chemotherapy.

The safety and efficacy of one-year administration of propiverine hydrochloride (BUP-4 tablets) were assessed in facilities affiliated with the Department of Urology of Yokohama City University School of Medicine. Changes in subjective symptoms showed significant improvement in mean frequency of urination in the daytime from 10.3 +/- 4.0 times before administration to 7.1 +/- 2.9 times 1 year after the start of administration, in mean frequency of voiding at night from 4.2 +/- 1.7 times to 2.1 +/- 1.1 times and in mean incidence of urinary incontinence from 2.9 +/- 2.1 times to 0.7 +/- 1.0 times. The final degree of overall improvement rate was 82.0% (41/50 cases). Adverse effects were observed 26 times in 22 patients, the incidence being 15.6% (22/141 cases). They consisted of digestive symptoms in 9.9% (6 events of dry mouth, 4 of constipation, 2 of abdominal discomfort, 2 of diarrhea and 1 of gastritis), urinary tract symptoms in 3.5% (4 of dysuria and 1 of residual urine), abnormal laboratory findings in 1.4% (increase in glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase or lactate dehydrogenase levels) and others (1.4%). These results provide further evidence of the safety and efficacy of propiverine hydrochloride (BUP-4 tablets) even when administered for a long-term in the treatment of patients with pollakiuria and urinary incontinence.

Inflammatory pseudotumor (IPT) is a benign tumorous lesion of unknown cause, which is composed of fibrous tissue with infiltration of plasma cells and lymphocytes. A 57-year-old male with gastritis was indicated to have hepatic dysfunction during observation of the course of gastritis at a nearby hospital. He was referred to our facility to undergo detailed examinations. When he visited our hospital for the initial examination, he had no subjective symptoms. His past medical history was unremarkable. There were no distinct abnormalities on the medical examination. Blood tests revealed a white blood cell count of 10400 / L, CRP of 0.29 mg/dl, AST of 31 IU/L, ALT of 46 IU/L, ALP of 583 IU/L and -GTP of 408 IU/L, showing a mild inflammatory reaction and elevated hepatobiliary enzymes. Abdominal ultrasonographic examination revealed a tumor mass approximately 4 cm in diameter in a lateral hepatic segment. The margin and center of the mass were hypoechoic and iso- to hyperechoic, respectively, and the inside of the mass was non-homogeneous. Needle biopsy revealed only inflammatory findings with no indications of malignancy. Since computed tomography (CT) of the abdomen, done 4 months after detection of the tumor mass, revealed the mass to have increased to approximately 6 cm in diameter, excision biopsy was considered. The CT taken 2 months later revealed the mass to have regressed to approximately 2 cm in diameter, but excision of the lateral hepatic segment was undertaken at the patient's request. As a result, the diagnosis of IPT of the liver was confirmed. Imaging findings of hepatic IPT are variable and specific findings are lacking. Since the rate of correct diagnosis with needle biopsy is also low, IPT of the liver is often very difficult to differentiate from malignant tumors. On the other hand, since it may show spontaneous regression, indications for surgery must be assessed very carefully.

A 63-year-old Japanese man whose white blood cell count and total-bilirubin and aminotransferase levels were elevated was referred to our hospital. Computed tomography did not reveal any abnormalities, and there was no evidence of gastritis or colitis on esophagogastroduodenoscopy. Although the patient had no history of drug use or allergies, a high concentration of eosinophils (80%) was noted. A liver biopsy revealed hepatitis with eosinophilic infiltration. The patient's alanine aminotransferase and eosinophil levels improved with the administration of steroids. A second biopsy, performed 6 months later, showed the improvement of the eosinophilic infiltration. The patient was diagnosed with eosinophilic hepatitis due to the presence of hypereosinophilic syndrome without the dysfunction of other organs.
