Abstract
The expression of cytotoxic molecules in feline intestinal T-cell lymphoma cells was examined immunohistochemically using endoscopic samples of 50 cases. Cases included 14 large-cell lymphomas (LCLs) and 36 small-cell lymphomas (SCLs). Most LCL and some SCL exhibited marked erosion and villous atrophy. Clonal T-cell receptor (TCR) gene rearrangement was detected in 10/14 (71%) LCL cases and 33/36 (92%) SCL cases. No clonal immunoglobulin heavy chain (IgH) gene rearrangement was detected. Immunohistochemically, all cases were positive for CD3 and negative for CD79α, CD30, CD56, and Foxp3. LCLs were positive for CD8 in 13/14 cases (93%), T-cell intracellular antigen 1 (TIA1) in 14/14 cases (100%), and granzyme B in 6/14 cases (43%). SCLs were positive for CD8 in 28/36 cases (78%), TIA1 in 33/36 cases (92%), and granzyme B in 2/36 cases (6%). TIA1- and granzyme B-positive neoplastic lymphocytes were predominantly observed in the mucosal epithelium of 10/50 cases (20%) and 6/50 cases (12%), respectively. No significant differences in survival time were found based on cell size or epitheliotropism. However, cases with TIA1+ and/or granzyme B+ neoplastic lymphocytes predominantly in the mucosal epithelium had significantly shorter survival times (P < .05), suggesting that mucosal epithelium infiltration of neoplastic cells with a cytotoxic immunophenotype is a negative prognostic factor. Therefore, intraepithelial cytotoxic lymphocytes may be associated with mucosal injury and impaired intestinal function, leading to a poor prognosis in cats with intestinal T-cell lymphoma.

Abstract
OBJECTIVE To examine the relationship of fear of fear and broad dimensions of psychopathology in panic disorder with agoraphobia over the course of cognitive behavioural therapy in Japan. METHODS A total of 177 Japanese patients with panic disorder with agoraphobia were treated with group cognitive behavioural therapy between 2001 and 2015. We examined associations between the change scores in Agoraphobic Cognitions Questionnaire or Body Sensations Questionnaire and the changes in subscales of Symptom Checklist-90 Revised during cognitive behavioural therapy controlling the change in panic disorder severity using multiple regression analysis. RESULTS Reduction in Agoraphobic Cognitions Questionnaire score was related to a decrease in all Symptom Checklist-90 Revised (SCL-90-R) subscale scores. Reduction in Body Sensations Questionnaire score was associated with a decrease in anxiety. Reduction in Panic Disorder Severity Scale score was not related to any SCL-90-R subscale changes. CONCLUSIONS Changes in fear of fear, especially maladaptive cognitions, may predict broad dimensions of psychopathology reductions in patients of panic disorder with agoraphobia over the course of cognitive behavioural therapy. For the sake of improving a broader range of psychiatric symptoms in patients of panic disorder with agoraphobia, more attention to maladaptive cognition changes during cognitive behavioural therapy is warranted.

Abstract
OBJECTIVE Spatio-temporal parameters are typically used for gait analysis. Although these parameters are measured by sophisticated systems such as 3D motion capture system or optoelectronic bars, these systems cannot be deployed easily because of their high costs, large space requirements and elaborate set-up. The purpose of this study is to develope a system for measuring spatiotemporal gait parameters using a laser range scanner during treadmill gait. APPROACH To calculate accurate spatiotemporal parameters, the differences between the laser range scanner measured values and the reference values obtained from a 3D motion capture system were investigated in thirty subjects. From measurements in time and position at foot contact/off, adjustments to compensate for the differences in time and position were derived. Then, to determine the validity of the proposed system, values from the proposed system and the reference system were compared in four additional subjects. MAIN RESULTS The results indicate that the data from the laser range scanner demonstrate certain differences in time and position compared with reference values. However, when compensation values were introduced, each spatiotemporal parameter correlated well with the reference values. SIGNIFICANCE This newer system is smaller, is easier to deploy and requires less training than the 3D motion capture system.

Abstract
The polarizer is one of the critical components in a high-power millimeter-wave transmission line. It requires full and highly efficient coverage of any polarization states, high-power tolerance, and low-loss feature. Polarizers with rounded shape at the edge of the periodic groove surface are designed and fabricated by the machining process for a mega-watt long-pulse millimeter-wave transmission line of the electron cyclotron resonance heating system in the large helical device. The groove shape of λ/8- and λ/4-type polarizers for an 82.7 GHz transmission line is optimally designed in an integral method developed in the vector theories of diffraction gratings so that the efficiency to realize any polarization state can be maximized. The dependence of the polarization states on the combination of the two polarizer rotation angles (Φλ/8, Φλ/4) is examined experimentally in a low-power test with the newly developed polarization monitor. The results show that the measured polarization characteristics are in good agreement with the calculated ones.

Abstract
Characteristics of the high-power reconnection heating were measured for the first time directly by two-dimensional measurements of ion and electron temperatures. While electrons are heated mainly inside the current sheet by the Ohmic heating power, ions are heated mainly by fast shock or viscosity damping of the reconnection outflow in the two downstream areas. The magnetic reconnection converts the energy of reconnecting magnetic field B(p) mostly to the ion thermal energy, indicating that the reconnection heating energy is proportional to B(p)(2).

Abstract
A 69-year-old male was admitted to the hospital for further examination of an abnormal shadow in the right lower lung fields. He was previously under medical treatment for right thoracic empyema. Chest computed tomography (CT) showed a solitary mass, 4.5 cm in diameter and broncofiberscopy evidenced a tumor in the right lower bronchus. The biopsy was performed and the tumor was diagnosed as a pleomorphic adenoma. Intraoperativefinding showed the tumor was 6 cm in gross, extended to the left atrium, and a daughter tumor was palpable in the middle lobe. The middle and lower lobe were resected. The tumor was located in S9, S10, 6 x 4 x 3.5 cm in size, 2 daughter tumor was found in the middle lobe, the pulmonary vein was thickened by tumor invasion. Pathohistologically, main tumor and daughter tumor showed malignant feature, were compatible with adenoid cystic cancer. Four years after operation, he is still now alive with home oxygen therapy.

Abstract
We have developed a highly sensitive and rapid oligonucleotide lateral-flow immunoassay (OLFIA), using a colloidal gold as an indicator, for the simultaneous detection of antigens and/or antibodies in specimen. This system can detect more than two types of antigens and/or antibodies in a single assay device at the same time. The device is basically composed of colloidal gold-labeled antibodies and oligonucleotide-labeled antibodies fixed in a conjugate pad, and the complementary oligonucleotide-labeled proteins are immobilized on a nitrocellulose membrane. If the target antigen is present in a specimen, the colloidal gold-labeled antibody and oligonucleotide-labeled antibody will make a complex with the antigen. Subsequently, the formed complex migrates to the place where complementary oligonucleotide is immobilized and is bound to the solid phase via the DNA-DNA interaction. As a result, more than two types of reactions can be detected on a single assay device by the combination of colloidal gold-labeled antibodies, different oligonucleotide-labeled antibodies and complementary oligonucleotide-labeled proteins immobilized at different places on a nitrocellulose membrane.

Abstract
Oral administration of red ginseng extracts (1% in diet for 40 weeks) resulted in the significant suppression of spontaneous liver tumor formation in C3H/He male mice. Average number of tumors per mouse in control group was 1.06, while that in red ginseng extracts-treated group was 0.33 (p<0.05). Incidence of liver tumor development was also lower in red ginseng extracts-treated group, although the difference from control group was not statistically significant. Anti-carcinogenic activity of white ginseng extracts, besides red ginseng extracts, was also investigated. In the present study, the administration of white ginseng extracts was proven to suppress tumor promoter-induced phenomena in vitro and in vivo. It is of interest that oral administration of the extracts of Ren-Shen-Yang- Rong-Tang, a white ginseng-containing Chinese medicinal prescription, resulted in the suppression of skin tumor promotion by 12-o-tetradecanoylphorbol-13-acetate in 7,12-dimethylbenz[a]anthracene-initiated CD-1 mice. These results suggest the usefulness of ginseng in the field of cancer prevention.

Abstract
We developed an improved enzymatic assay of D-sorbitol in human erythrocytes by employing highly specific D-sorbitol dehydrogenase from Pseudomonas sp. (EC 1.1.1.14) and replacing perchloric acid (HClO4) and potassium carbonate (K2CO3), generally used for deproteinization, with sodium hydroxide (NaOH) and zinc sulphate (ZnSO4). In this assay, erythrocytes were separated from plasma by centrifugation and washed once with physiological saline. Subsequently, the erythrocytes were lysed with distilled water and proteins precipitated with NaOH and ZnSO4. After centrifugation, the resulting colourless supernatant was mixed with a glycine buffer (pH 9.0) containing NAD+ and D-sorbitol dehydrogenase. After incubation for 30 min at 37 degrees C, the NADH produced was measured fluorimetrically. The fluorescence intensities were corrected for sample blanks, and the values of D-sorbitol were normalized for haemoglobin content. The method had an analytical range of 1-180 micromol/L. The intra- and inter-assay precisions were < 3.3% and < 5.8%, respectively. The detection limit was 0.65 micromol/L. In terms of the linearity, precision and sensitivity, the improved method using NaOH and ZnSO4 was superior to the conventional method using HClO4 and K2CO3.

Abstract
Hepatocyte growth factor (HGF) is postulated to play an important role in the repair of pulmonary epithelium in acute lung injury. To evaluate the role of HGF in bacterial pneumonia, the kinetics of HGF production and the cellular sources of HGF have been examined in the lungs of mice that had been intratracheally challenged with Pseudomonas aeruginosa. Neutrophil accumulation in the airway occurred immediately, reached a peak at 36 h, and then progressively declined by 14 d after infection. We found a biphasic pattern of HGF messenger RNA expression and protein synthesis in the lung after bacterial infection. The first peak for HGF production was found at 6 h after infection, and the primary source of HGF was shown to be bronchial epithelial cells. Interestingly, the second peak for HGF production, which was found around 48 to 72 h after infection, was closely associated with the increase in the percentage of alveolar macrophages (AMs) that became positive for myeloperoxidase, indicating phagocytosis of apoptotic neutrophils. The cellular source of the second peak was found to be AMs. Further, murine AMs which phagocytosed apoptotic neutrophils induced higher levels of HGF production in vitro. These results strongly indicate a novel mechanism of HGF production by AMs, which are phagocytosing apoptotic neutrophils, and the pivotal role of AMs in the healing and repair of damaged pulmonary epithelium through the production of HGF.

Abstract
A 72-year-old woman was admitted to our hospital for further evaluation of a abnormal shadow in left middle lung field. The patient had undergone right mastectomy for infiltrating ductal carcinoma 19 years ago. She had no symptom, but had a time of mass X-ray screening this year. Chest CT finding showed a nodule 2 cm in diameter with slight irregular margin in S6 of left lung. We couldn't determine preoperatively that this tumor was a metastatic lesion or a primary lung cancer. And first, tumor was taken out for intraoperative frozen section diagnosis. Pathologist didn't diagnose whether this tumor was a metastatic or primary. So, we performed left lower lobectomy and mediastinal lymphadenectomy. On postoperative histopathologic finding lung cancer resembled well previous breast cancer. In immunohistochemical study cancer cells from lung and breast of the patient were respectively positive for anti Estrogen Receptor (ER) and anti Gross Cystic Disease Fluid Protein-15 (GCDFP-15). In conclusion lung cancer was diagnosed as a metastatic lesion from breast cancer 19 years ago. The patient has been well 2 years postoperatively without recurrence. In this case immunohistochemical examination was very useful for differentiation metastatic lesion and primary one.

Abstract
OBJECTIVE This study aimed to determine the clinical difference of pneumonia between penicillin-resistant and penicillin-sensitive Streptococcus pneumoniae. METHODOLOGY Forty-nine cases in 46 patients of pneumococcal pneumonia were studied from December 1992 to May 1997. There were 24 cases (in 22 patients) of penicillin-resistant pneumococci (PRSP) pneumonia which were compared with 25 cases (in 24 patients) with penicillin-sensitive pneumococci (PSSP). RESULTS Both the mean age and the underlying disease states did not differ between the two groups. However, hospital-acquired pneumonia and previous use of antibiotics were observed in eight (33.3%) and 12 (50.0%) patients in PRSP compared with three (12.0%) and two (8.0%) in PSSP, respectively. The clinical efficacy rate and bacteriological eradication rates were 87.5 and 87.5% in PRSP compared with 87.5 and 87.0% in PSSP, respectively. Minimum inhibitory concentration (MIC) of antibiotics against 30 pneumococcal isolates was examined, and 10 strains ranged from 0.10-0.78 microg/mL and five strains were more than 1.56 microg/mL against penicillin G, while the MIC showed higher resistance to other antibiotics except for the carbapenems. Serotyping of the isolates by antiserum revealed differences in the predominant types PRSP (19F) and PSSP (6A,9V) [corrected]. CONCLUSIONS We must care for not only community-acquired infection but also nosocomial transmission of PRSP pneumonia. Most patients with infections due to PRSP tended to have a milder illness with a good outcome (no patient died). As such it appears that empiric therapy for pneumococcal pneumonia does not require modification from what is recommended at present. However, in patients with infection due to highly resistant strains, and who are not responding to conventional therapy should have their treatment modified according to subsequent susceptibility testing.

Abstract
A 58-year-old man was admitted to our hospital for detailed examination of continuous cough. On a chest X-ray film, abnormal shadow was detected in the right lower lung field. Preoperative examination findings didn't lead to a definitive diagnosis. Under thoracoscopy partial resection of the lung was performed to rule out a malignant lesion. Intraoperative pathologic finding revealed a granulomatous lesion. And, final pathological diagnosis showed to be a pulmonary dirofilariasis. His postoperative course was not eventful. On 20 th day he discharged postoperatively. Now, under the Pet-boom the disease has been reported increasingly. But it is difficult to find the disease preoperatively. So, it is real to be operated for differentiate from a malignant lesion. Recently in many cases open lung biopsy, has been undergone with less invasive procedure such as thoracoscopy and VATS. It will be mainstream in future.

Abstract
The immunosuppressive effects of a leukotriene B4 (LTB4) receptor antagonist, ONO4057, on liver allotransplantation in rats were evaluated, and the levels of prostaglandin E2 (PGE2) in the liver tissue during rejection of the allografts examined. The rats were divided into four groups: group 1: Lewis rats (LEW) given a sham operation with dimethyl sulfoxide (DMSO); group 2: LEW given syngenic orthotopic liver transplantation (OLT) from LEW, with DMSO; group 3: LEW given allogenic OLT from ACI rats (ACI), with DMSO; and group 4: LEW given allogenic OLT from ACI, with ONO4057 as 10, 30, or 100 mg/kg per day dissolved in DMSO to subgroups 4a, 4b, and 4c, respectively. Histological examinations were performed, survival times monitored, and liver tissue PGE2 levels 3, 5, 7, and 14 days after transplantation measured. The mean graft survival times in groups 4a, b, and c, at 37.5 +/- 10.4, 52.2 +/- 24.4, and 34.0 +/- 4.9 days (mean +/- SEM), respectively, were significantly longer than that in group 3 (at 13.0 +/- 3.2 days). Moreover, the levels of tissue PGE2 in the liver allografts in group 4a were significantly higher than those in group 3 on days 5 and 7. These results suggest that ONO4057 has an immunosuppressive effect on liver allotransplantation since it reduces the activities of LTB4 which augments immune responses, and also because it indirectly increases the PGE2 level.

Abstract
Structural characterization of sulfated and sialyl Lewis (Le)-type glycosphingolipids performed by fast atom bombardment (FAB) and electrospray ionization (ESI) mass spectrometry is described. Both FAB and ESI collision-induced dissociation tandem mass spectrometry (CID-MS/MS) of acidic glycosphingolipids allowed identification of the sulfated or sialyl sugar, and provided information on the saccharide chain sequence. The negative-ion tandem FABMS of sulfated Le-type glycosphingolipids having the non-reducing end trisaccharide ion as the precursor can be used to differentiate the Le(a)- and Le(x)-type oligosaccharides. The ESI CID-MS/MS of multiple-charged ions provided even more detailed structural information, and some of the useful daughter ions appeared with higher m/z values than the precursor because of a lower charge-state. These methodologies can be applied to the structural analyses of glycoconjugates with much larger molecular masses and higher polarity, such as the poly-sulfated and sialyl analogues.

Abstract
The structural characterization of intact polysialogangliosides by electrospray-ionization mass spectrometry (ESIMS) and tandem mass spectrometry (MS/MS) is described. The negative-ion ESI mass spectra of gangliosides, such as a tetrasialoganglioside GQ1b, showed molecularly related ions with high sensitivity and accuracy. Collision-induced dissociation (CID) MS/MS provided adequate information to characterize the number and positions of sialic acids. ESIMS and CIDMS/MS techniques were applied successfully also in the positive-ion mode for characterization of intact gangliosides. Two isomeric disialogangliosides, GD1a and GD1b, are distinguishable from one another by CIDMS/MS in both negative- and positive-ion modes. The technique is readily applicable to structural analyses such as determining the positional isomers of glycoconjugates.

Abstract
It has been suggested that the number of argyrophilic nucleolar organizer regions (AgNORs) correlates with cellular activity and the aggressiveness of malignancy. The mean number of AgNORs per nucleus may, therefore, be a prognostic factor for hepatocellular carcinoma (HCC). The purpose of this study was to evaluate the prognostic significance of the number of AgNORs in HCC. The silver-staining technique was applied to surgically resected specimens to indicate AgNORs. Eighty-nine of the specimens were of HCC, 23 were of normal liver adjacent to HCC, and 32 were of cirrhotic liver adjacent to HCC. The number of AgNORs of HCC (mean +/- SD, 3.26 +/- 1.23) was significantly higher than those of normal liver (1.37 +/- 0.13) and cirrhotic liver (1.49 +/- 0.14). The number of AgNORs was significantly correlated with serum alpha-fetoprotein level, tumor size, portal vein invasion, and Edmondson-Steiner histological grade. In patients undergoing curative resection, the survival rate of those with a high number (> 3.04) of AgNORs was significantly worse than that of those with a low number (< or = 3.04) of AgNORs. Multivariate analysis showed that the number of AgNORs was a significant prognostic indicator in patients without portal vein invasion, and portal vein invasion was the only significant variable when all patients undergoing curative resection were assessed together. The results of this study suggest that the number of AgNORs is useful as an indicator of the grade of malignancy and as a predictor of the prognosis of patients with HCC who do not have portal vein involvement.

Abstract
Vascular invasion and intrahepatic metastasis by hepatocellular carcinoma are important factors predisposing to tumor recurrence. Recurrences of this malignancy occur frequently in residual liver, and its prevention is one of the most important factors in obtaining better surgical survival. Fifty patients who underwent hepatectomy for invasive hepatocellular carcinoma with vascular invasion and/or intrahepatic metastases were studied to evaluate the effect of adjuvant bolus hepatic arterial infusion of iodized poppyseed oil (Lipiodol) containing anticancer drugs in preventing recurrence and in prolonging survival. Patients were assigned to two treatment groups. Twenty-three of the fifty patients received adjuvant bolus infusion of Lipiodol containing doxorubicin and mitomycin C, whereas 27 patients received no therapy. The disease-free survival rate for the patients who received adjuvant therapy was significantly better (p < 0.05) than that for those who did not when measured at 172, 516, 688 and 860 days after hepatectomy, and the disease-free survival curve for patients with adjuvant therapy was significantly (p = 0.0237) better than that without adjuvant therapy. The cumulative survival rates and curves were not significantly different between the two groups. While adjuvant hepatic arterial infusion of Lipiodol containing anticancer drugs was effective in improving disease-free survival, the effect was not satisfactory. Further trials of adjuvant chemotherapy are required to improve the surgical survival of hepatocellular carcinoma patients.

Abstract
Fast atom bombardment tandem mass spectrometry has been used in the characterization of non-, mono-, di- and trisulfated disaccharides from chondroitin sulfate, dermatan sulfate and hyaluronan. The positional isomers of the sulfate group of mono- and disulfated disaccharides were distinguished from each other by both positive- and negative-ion fast atom bombardment tandem mass spectra, which gave sufficient information characteristic of the isomers. The anomeric isomers of nonsulfated disaccharides were characterized by the technique in the positive-ion mode. This fast atom bombardment collision induced dissociation mass spectrometry/mass spectrometry technique was also applied successfully to the characterization of trisulfated disaccharide.

Abstract
BACKGROUND/AIMS Prognostic analysis on hepatocellular carcinoma (HCC) in patients undergoing hepatectomy is necessary to determine the clinical value of hepatectomy on prognosis. METHODS Survival and disease-free survival were analyzed in 104 HCC patients undergoing hepatectomy using clinicopathologic factors by univariate and multivariate analyses. The value of the International Union Against Cancer (UICC) TNM classification on prognosis was assessed in the patients. RESULTS In multivariate analysis, portal vein invasion was the most influential factor. The difference between stage 1 and 2 or stage 3 and 4A using UICC's TNM classification was not significant with respect to survival or disease-free survival. The UICC's classification was modified as follows; stage 1, solitary tumor without vascular invasion; stage 2, solitary or multiple tumor(s) involving adjacent to vessel branch; stage 3, tumor(s) involving major vessel branch or with regional lymph nodal metastasis; and stage 4, tumor(s) with distant metastasis. The differences between each stage in the modified classification were significant with respect to disease-free survival. CONCLUSIONS The UICC's TNM classification was not of prognostic significance. Further studies on survival in patients with HCC are necessary to evaluate the value of the UICC's TNM classification; some modification may be necessary.

Abstract
A 36-year-old man who complained of bloody sputum showed a mass-like shadow in the right upper lung field on chest X-ray, which was diagnosed as adenocarcinoma by sputum cytology in August, 1990. Since his clinical stage was too advanced for curative operation, chemotherapy was started on October 1, 1990. On October 26, he brought up a polyp-like mass, and was found to have polypoid tumors on the bilateral tonsils and nasopharynx, which were biopsied and diagnosed as poorly-differentiated adenocarcinoma. On November 21, CT of the face showed soft tissue density tumors in the bilateral paranasal sinuses. According to the clinical course, all tumors were thought to be metastatic lesions. Since he had suffered from epistaxis and nasal obstruction due to the enlargement of metastatic tumors, nebulization chemotherapy and palliative resection were performed. In February 1991, he developed severe headache due to brain metastasis. Despite irradiation therapy, he died from cerebral intra-tumorous hemorrhage on February 22. We reported a rare incurable case of lung cancer with metastasis to the nasopharynx and paranasal sinuses.

Abstract
One hundred and thirty-two patients with hepatocellular carcinoma in stages III and IV were studied. Seventy-six patients who underwent hepatectomy were divided into three groups: relative curative resection (RC: n = 30), relative noncurative resection (RNC: n = 30) and absolute noncurative resection (ANC: n = 16). Fifty-six patients were treated by non surgical procedures such as hepatic arterial infusion, transcatheter arterial embolization, ethanol injection and hyperthermia. The cumulative survival rate of hepatectomy patients was significantly better than that of non-surgically treated patients. The most significant prognostic factor was the presence of the portal venous invasion. In the patients without tumor thrombi or with tumor thrombi found microscopically, the cumulative survival rates of both RC and RNC were significantly better than those of ANC and non-surgically treated patients, but in the patients with tumor thrombi found grossly, there was no difference between hepatectomy patients and non-surgically treated patients. These results indicate that surgical treatment for advanced hepatocellular carcinoma improve the prognosis of the patients without tumor thrombi found grossly.

Abstract
Postoperative adjuvant locoregional chemotherapy was performed on patients who underwent hepatic resection for hepatocellular carcinoma with permeation of tumor into portal vein and/or into hepatic vein and/or intrahepatic metastasis to prevent recurrence. Twenty patients received intra-hepato-arterial infusion of chemotherapeutic drugs or Lipiodol, or transcatheter arterial embolization as adjuvant therapy, and 25 patients did not receive the therapy. There was no significant difference in the recurrence rate between the two groups, and disease-free-survival would not be improved significantly by adjuvant therapy. But the disease-free-survival was improved in patients who underwent relative noncurative hepatectomies. Median duration from the hepatic resection to the recurrence was prolonged by adjuvant therapy, but no significant difference was noted between the two groups. Serious hepatic injury was a side effect of adjuvant therapy in one patient. Therefore great care was necessary when performing the therapy. Further study on choice of the drugs and methods was considered necessary to obtain more effective therapy.

Abstract
A 65-year-old female suffering from lumbago, headache, and hypertension had been treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. On June 13, 1990, 2 weeks after the commencement of loxoprofen administration, she developed cough and low grade fever. She was treated with antibiotics and NSAIDs without improvement. Laboratory data showed marked eosinophilia (2200/mm3), elevation of IgE (3090 IU/ml), and liver dysfunction. Her chest X-ray revealed no active lesion, but the percentage of eosinophils in BALF was elevated (38%). Because drug-induced eosinophilic pneumonia was suspected, all drugs were discontinued. Her symptoms improved and the abnormalities of laboratory data normalized. The lymphocyte stimulation test was weakly positive with three NSAIDs (loxoprofen, pranoprofen, and alminoprofen). The challenge test by loxoprofen reproduced eosinophilia and liver dysfunction, suggesting that she had loxoprofen-induced eosinophilic pneumonia. To our knowledge, this is the first reported case of loxoprofen-induced lung injury.

Abstract
The cell cycle of Familial Polyposis Coli (FPC) has been determined by a flow cytometric (FCM) DNA/bromodeoxyuridine (BrdUrd) bivariate analysis. Specimens were obtained from one FPC cancer patient and, for our controls, from 8 single colon cancer patients and from 8 gastric cancer patients who underwent a colectomy. Procedurally, 1 g i.v. injection of BrdUrd was administered 5 to 7 hours before the resection. Later, the BrdUrd-labeling index (BULI) and the potential doubling time (Tpot) were measured by FCM. No significant differences were uncovered between the BULI of the cancer in the FPC patient and that of our controls, or between the BULI of the unaffected mucosa of the FPC patient and that of the controls. Further, with regard to the FPC patient, the mean BULI of the cancer was significantly higher than that of the adenoma and than that of the unaffected mucosa. Also, the mean Tpot of the cancer was significantly shorter than that of the unaffected mucosa. These results suggest that the BULI and the Tpot may change when an adenoma is generated from the unaffected mucosa in FPC patients.

Abstract
Contractile motility of the gallbladder and plasma cholecystokinin (CCK) responses to egg yolk administration were studied in 28 diabetic patients and 12 normal subjects. The patients were divided into three groups: group A (n = 10) had no diabetic neuropathy, group B (n = 8) had diabetic neuropathy with little autonomic neuropathy, and group C (n = 10) had advanced diabetic autonomic neuropathy. In groups A and B, contraction of the gallbladder after egg yolk administration was not significantly different from that of normal subjects. However, in group C, gallbladder contraction was impaired (p less than 0.01-0.05), compared with that in normal subjects. After the administration of egg yolk, plasma CCK levels increased from 12.4 +/- 4.5 to 25.3 +/- 12.0 pg/ml in normal subjects. In group A, plasma CCK levels increased from 17.9 +/- 8.5 to 39.3 +/- 14.2 pg/ml, and in group B, from 15.2 +/- 5.1 to 38.3 +/- 9.9 pg/ml. In group C, however, plasma CCK levels increased from 33.1 +/- 13.9 to 72.4 +/- 31.9 pg/ml, and fasting CCK levels and responses to egg yolk were significantly higher than those in normal subjects and in groups A and B (p less than 0.01-0.05). In conclusion, this study showed that in a group of diabetic patients with autonomic neuropathy, gallbladder contraction was impaired despite the exaggerated CCK response to egg yolk.

Abstract
Gastrointestinal protein loss was measured using Tc-99m labeled human serum albumin in a patient with giant hypertrophic gastritis. Gastric secretion was aspirated via a nasogastric tube and measured for radioactivity after intravenous injection of Tc-99m albumin. Assessment of radioactivity of the collected gastric secretion yielded a total radiocount of 98.7 kilocounts per minute within 6 hours, which is equivalent to 1.1% of the total dose. Therefore, at least 1.1% of the circulating albumin was excreted into the gastric cavity within 6 hours, and, since simultaneous abdominal imaging did not demonstrate obvious accumulation of tracer in the gastrointestinal tract, protein loss was thought to be due to giant gastric rugae of the resected stomach. It was concluded that Tc-99m albumin is a valuable means for detection of the site of protein loss in patients with protein-losing gastroenteropathy. This method has several advantages in the clinical setting; it is less time consuming, easy to perform, and provides quantitative and qualitative assessment of protein loss.
