Abstract
Ninjinyoeito (NYT), a traditional Japanese medicine, is effective for improving physical strength and treating fatigue and anorexia. Recently, a clinical report revealed that NYT ameliorates cognitive dysfunction in Alzheimer's disease (AD) patients, although the mechanisms remain unclear. AD is a neurodegenerative disorder accompanied by a progressive deficit in memory. Current therapeutic agents are largely ineffective in treating cognitive dysfunction in AD patients. In this study, we investigated the effects of NYT on spatial memory impairment in a rat model of dementia. Rats were prepared with transient cerebral ischemia and intraventricular injection of β-amyloid1-42 for 7 days (CI + Aβ). NYT was orally administered for 7 days after cerebral ischemia. We evaluated spatial memory using the Morris water maze and investigated the expression of α-amino-3-hydroxy-5-4-isoxazole propionic acid receptor subunits, the phosphorylation level of glutamate receptor A (GluA)1 at serine sites S831 and S845, and the Ca2+/calmodulin-dependent protein kinase II (CaMKII) in the hippocampus and prefrontal cortex of CI + Aβ rats. In the CI + Aβ rats, NYT treatment shortened the extended time to reach the platform. However, NYT did not restore the decrease in the hippocampal GluA1, GluA2, or CaMKII expression but increased prefrontal cortical phosphorylation levels of S845-GluA1 and CaMKII. Therefore, NYT may alleviate spatial memory impairment by promoting glutamatergic transmission involved in the phosphorylation of S845-GluA1 and CaMKII in the prefrontal cortex of CI + Aβ rats. Our results suggest that NYT is a valuable treatment for AD patients.

Abstract
Abstract
Background
The trial collected prospective data from physiology measurements of borderline lesions in five Czech, one Japan and one Argentinian cathlabs. The main purposes were to analyze diagnostic agreement between FFR (fractional flow reserve) and iFR (instantaneous wave free ratio) examinations and to find possible explanations for discrepant results.
Methods
FFR and iFR examinations were analyzed using Philips-Volcano console and coronary flow reserve (CFR) was analyzed by using Combomap machine Philips-Volcano. Hyperemia for FFR and CFR measurements was induced by intracoronary administration of adenosine. We used CFR as a truth for comparison between FFR and iFR, because CFR has higher impact on patients prognosis than pressures indices.
Results
Data were collected from February 2016 to June 2019 and the database includes 1.789 examinations from 1.492 patients (282 of them, 15.8%, with ACS). CFR were measured in 343 lesions in 293 patients. (ACS 31.2%). Overall correlation between FFR and iFR is high (R=0.86 p<0.0001). The FFR/iFR discrepancy occurred in 84 measurements (24.5%), more frequently it was FFRp (positive) / iFRn (negative) type of discrepancy (65, 18.9%) compare to FFRn/iFRp (19, 5.5%) one. There was no difference in occurrence of FFR/iFR discrepancy in stable patients and ACS ones (25.1%vs. 22.4%, p=0.59). The CFR correlated better with iFR than with FFR (R=0.56, p<0.0001 vs. R= 0.36, p<0.0001) (see table). In lesions with FFRp/iFRn type of discrepancy we found substantially higher CFR value compared to FFR/iFR agreement group (2.4±0.7 vs. 1.5±0.5, p<0.0001). Unlike to FFRn/iFRp discrepancy, where CFR value was similar with agreement group (1.4±0.1 vs. 1.5±0.1, p=0.25)
Conclusion
The FFR/iFR discrepancy occurred in almost one quarter of examinations. Correlation between CFR and iFR is better than between CFR and FFR. High flow is probably one of the main reason for FFRp/iFRn type of discrepancy.

Abstract
Abstract
Background
Recently, some studies have highlighted proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors produce incremental low-density lipoprotein cholesterol (LDL-C) lowering effect. However, it is unknown whether the lipid composition of plaque changes is associated with serum LDL-C reduction due to PCSK9 inhibitors administration.
Purpose
The purpose of this study was to determine the effects of PCSK9 inhibitor (PCSK9i) on coronary plaque component in patients with a history of coronary artery disease (CAD) assessed by near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS).
Methods
A total of 67 non-culprit coronary segments were identified in 34 patients. These lesions were analyzed utilizing NIRS-IVUS at baseline and follow-up coronary angiography (CAG). The subjects were divided into two groups according to lipid-lowering treatment; administration of PCSK9i group (PCSK9i: 19 segments, 9 patients) and traditional statin treatment group (Control: 48 segments, 25 patients). The change of lipid-rich plaque distribution between baseline and follow-up NIRS-IVUS was defined as the change of maximal lipid core burden index (LCBI) score for each of the 4-mm longitudinal segments (maxLCBI4mm).
Results
Mean duration from baseline to follow-up CAG was 239.4±52.4 days in the PCSK9i group and 341.0±84.1 days in the Control group (p<0.001). Despite the higher total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the PCSK9i group at baseline (206.6±40.9 mg/dl vs. 168.5±37.1 mg/dl, 131.5±35.4 mg/dl vs. 100.0±29.5 mg/dl; respectively, p<0.001 for both), the PCSK9i group was significantly lower TC and LDL-C at the follow-up (111.5±23.5 mg/dl vs. 157.4±27.8 mg/dl, 40.8±15.7 mg/dl vs. 86.2±19.6 mg/dl; respectively, p<0.001 for both). Furthermore, the PCSK9i group induced greater regression of maxLCBI4mm than that of Control group (99.6±156.6 vs. 27.9±118.0, p=0.046) (Figure).

Conclusion
Compared with traditional statin therapy, PCSK9i treatment resulted in a greater decrease in lipid component in non-culprit coronary plaques. Therefore, PCSK9i may be useful option in preventing from adverse coronary events for the patients with CAD.

Abstract
Balloon occlusion is a potential method for inducing hyperemia to measure post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR). The objective of this study was to determine the clinical usefulness of post-occlusional hyperemia. FFRs measured using post-occlusional hyperemia caused by 30 (FFRoccl30) and 60 s (FFRoccl60) of balloon occlusion after PCI were compared in 60 lesions from 60 patients. The duration of hyperemia was also measured. There was a strong correlation between FFRoccl30 and FFRoccl60 (r = 0.969, p < 0.01). The duration of hyperemia was significantly longer with FFRoccl60 than with FFRoccl30 (68 ± 23 vs. 37 ± 15 s, p < 0.01). The time required for pullback curve analysis was around 45 s. However, in 7 (12%) cases, the duration of hyperemia with FFRoccl60 was < 45 s, which was not enough for pull-back curve analysis. To predict the duration of hyperemia with FFRoccl60 ≥ 45 s, the receiver operating characteristic curve analysis revealed a cut-off value of 25 s of hyperemia with FFRoccl30. FFRoccl30 is sufficient for diagnostic purposes. FFRoccl60 is suitable for pull-back curve analysis in select cases based on predictions made using the duration of hyperemia with FFRoccl30.

Abstract
OBJECTIVE To assess the performance of angiography derived Fractional Flow Reserve (FFRangio) in multivessel disease (MVD) patients undergoing angiography. BACKGROUND FFR is the reference standard for physiologic assessment of coronary stenosis and guidance of revascularization, especially in patients with MVD, yet it remains grossly underutilized. The non-wire based FFRangio performs well in non-MVD patients, but its accuracy in MVD is unknown. METHODS A prospective clinical study was conducted at Gifu Heart Centre, Japan. Patients underwent physiologic assessment of all relevant coronary lesions using wire-based FFR (wbFFR) and FFRangio. Primary outcome was diagnostic performance (sensitivity, specificity, accuracy) for FFRangio with wbFFR as reference. Other outcomes were the correlation between wbFFR/FFRangio, time required for wbFFR/FFRangio measurements, and the effect of wbFFR/FFRangio on the reclassification of coronary disease severity. RESULTS Fifty patients (118 lesions in total) were included. Mean age was 72 ± 9 years, 72% were male, 36% had triple vessel disease and the average SYNTAX score was 13. The mean measurement of wbFFR and FFRangio were 0.83 ± 0.12 and 0.81 ± 0.11, respectively. Accuracy, sensitivity and specificity for FFRangio were 92.3% (95% CI 79.1-98.4%), 92.4% (95% CI 84.3-97.2%) and 92.4% (95% CI 87.4-97.3%), respectively. Pearson's r between wbFFR and FFRangio was 0.83. FFRangio measurement was faster than wbFFR (9.6 ± 3.4 vs. 15.0 ± 8.9 min, p < 0.001). CONCLUSIONS In patients with MVD, FFRangio shows good correlation and excellent diagnostic performance compared to wbFFR, and measuring FFRangio is faster than wbFFR. These results highlight the potential clinical benefits of utilizing FFRangio among patients with MVD.

Abstract
We report a 53-year-old Japanese woman who had recurrent orbital myositis for 14 years. She exhibited mild muscle weakness in proximal limbs 13 years after the onset of orbital myositis. An electromyogram revealed myopathic potentials and denervation potentials in proximal limb muscles. Quadriceps biopsy showed infiltrates of mononuclear cells around intramuscular vessels and mild degenerative changes in muscle cells. These findings indicate that the present case belongs to the spectrum of localized nodular myositis.

Abstract
Transforming growth factor-beta1 (TGF-beta1) inhibits the growth of a variety of epithelial cells; however, in many types of tumors it loses its inhibitory effect. p21(WAF1/CIP1), one of the cyclin-dependent kinase (Cdk) inhibitors induced by TGF-beta1, is considered a downstream effector of the growth-inhibitory function of TGF-beta1. We assessed the clinicopathologic significance of TGF-beta1 and p21 expression in resectable invasive ductal carcinoma (IDC) of the pancreas. Immunohistochemical examination of the expression of TGF-beta1 and p21 in 62 patients revealed positive expression of TGF-beta1 in 28 (45%) and of p21 in 25 (40%) of the 62 patients, and a significant correlation between the two expressions. The survival curve of patients with TGF-beta1(+) tumors was significantly higher than that of patients with TGF-beta1(-) tumors; p21(+) patients showed a higher survival curve than did p21(-) patients, but the difference was not statistically significant. Simultaneous analysis of TGF-beta1 and p21 expression showed that the patients with TGF-beta1(+)/p21(+) tumors had a significantly better prognosis than the others. Multivariate analysis showed that TGF-beta1 was a significantly low risk factor for death due to IDC. The concurrent evaluation of TGF-beta1 and p21 expression would be an effective tool in the prediction of the prognosis of patients with pancreatic cancer.

Abstract
We reviewed 27 cementless primary total hip replacements in patients with osteoarthrosis secondary to congenital dysplasia of the hip. Autogenous bone grafting was used as augmentation. On average the follow-up period was 9 years. Two hips were revised and three acetabular components were considered loose. In hips with loose cups the average graft coverage was significantly greater than in stable hips. The use of a cementless acetabular component is encouraging for reconstruction, although extensive grafting should be avoided. Our study suggests that cementless reconstruction in dysplastic hips yields a satisfactory outcome.

Abstract
Serial radiographic measurements of polyethylene wear were performed in 38 hips (33 patients) with primary cementless total hip arthroplasty (THA). The average follow-up period was 131.8 months. All prostheses were assessed as radiographically stable at the latest follow-up. A two-dimensional method was used to calculate the relative migration of the femoral head center to the cup center. The average total linear wear and wear rate were 1.22 mm and 0.11 mm/year, respectively. The degree of wear in the first 2 postoperative years accounted for nearly 40% of the total wear at the end of the study (average follow up: 131.8 +/- 10.0 months, +/-SD). The migration of the femoral head at an average period of 3. 4 months after operation accounted for 56% of the amount of wear in the first 2 years. Wear rate decreased gradually with time and stabilized after the fourth year. However, in 2 patients, a progressive increase in the wear rate was associated with severe osteolysis and failure of THA. Both creep and wear contributed to the femoral penetration into the polyethylene liner. The influence of creep cannot be ruled out, especially in the early period after operation. Polyethylene wear is a multifactorial process, and the study of individual wear patterns might be useful in identifying patients who are at risk of late failure of THA.

Abstract
BACKGROUND Considering the difficulties in pancreas transplantation, the development of an artificial pancreas can be one of the new approaches. The present study was designed to assess whether or not Chinese hamster ovary (CHO) cells, which were transfected with the human proinsulin (hPI) gene, secrete immunoreactive insulin (IRI) and respond to glucose loading. MATERIALS AND METHODS A complementary DNA encoding hPI was obtained by polymerase chain reaction amplification from human pancreatic tissue and was inserted into the plasmid pcDNA I/NEO to construct an expression vector for the hPI gene. CHO cells were transfected with hPI gene using lipofectin, and the hPI gene-expressing clones (CHO/I) were selected. RESULTS Five clones of CHO/I cells, releasing IRI into the culture supernatant, were separated. Immunohistochemistry with a monoclonal antibody demonstrated the IRI in the cytoplasm of CHO/I cells, and transmission electron microscopic examination demonstrated the prominently developed mitochondria, but no secretion granules. ELISA assay demonstrated the secretion of IRI into the culture supernatant of CHO/I, but CHO/I cells did not respond to the glucose loading. When CHO/I cells were transplanted subcutaneously into the back of nude mice, the growing tumors secreted IRI. CONCLUSIONS These results demonstrate that the hPI gene can be transfected into mammalian cells and function in vivo, and suggest that this kind of gene technology may be applicable in the development of an artificial pancreas.

Abstract
We designed 2 new types of proximally coated stems (the FMS and FMS-anatomic) based on the endosteal geometry of femora with congenital dislocation or dysplastic hip. The FMS was symmetric while the FMS-anatomic was asymmetric. We compared the proximal fit and fill to the femoral canal, contact stress, relative motion, and load transfer to the femur of 5 stems (FMS, FMS-anatomic, Omnifit, Omniflex, and individual stem) using three-dimensional computer simulation and finite element analysis. The FMS and FMS-anatomic showed a significantly greater fit and fill than conventional stems. The dispersion of the contact stresses and reduction of relative motions in the proximal area were the best in the FMS-anatomic compared to other stems with the exception of the individual stem. In addition, the FMS-anatomic stem transferred most of the load to the proximal femur. Our results suggest that the FMS-anatomic should provide better biomechanical stability at least in the early postoperative period.

Abstract
BACKGROUND Although the surgical results of the modified Fontan operation continues to improve, there are various advantages and disadvantages in terms of the post operative condition associated with the Fontan modifications. Late morbidity and mortality are mainly due to arrhythmias, thromboembolic complications, systemic venous hypertension and infective endocarditis. We reported our experience of the modified Fontan operation to determine an appropriate procedure for each patient. METHODS AND RESULTS Seven patients (ranging from the age 1-14 years) underwent a modified Fontan operation including a lateral tunnel (n = 1), extracardiac conduit (n = 2) and autogenous atrial tunnel (n = 4). There was one hospital death due to sepsis in which the patient underwent lateral tunnel procedure. The mean follow up of another six patients was 20 months (ranging from 1-39 months) and all patients were classified as NYHA class I, and remained in normal sinus rhythm without any thromboembolic complications. CONCLUSIONS When using the autogenous atrial tunnel, there are potential advantages; it is not associated with thromboembolism or endocarditis and has growth potential. However, in high-risk patients with increased pulmonary vascular resistance, impaired ventricular function and pre-operative atrial arrhythmias, it appears reasonable to use an extracardiac conduit.

Abstract
Heavy water (deuterium oxide: D2O) contains a neutron and a proton in its hydrogen atoms and shows a variety of biologic activities different from normal light water. In the present study the cytotoxic and cytostatic activity of D2O was assessed using a BALB/c-3T3 fibroblast cell line and four human digestive organ cancer cell lines, i.e. HepG2 hepatic, Panc-1 pancreatic, KATO-3 gastric and Colo205 colonic cancer cell lines. Against four cancer cell lines, D2O showed significant cytotoxic and cytostatic effects in a MTT assay and a Trypan blue dye exclusion assay, at concentrations higher than 30% D2O. These effects were time and dose dependent, and the IC50 after 72 h of culture ranged from 20 to 30% D2O in the Trypan blue dye exclusion assay and from 30 to 50% D2O in the MTT assay. By contrast, IC50 for the 3T3 fibroblast cell line after 72 h of culture was about 15% in the Trypan blue dye exclusion assay and 50% inhibition was not achieved in the MTT assay. Furthermore, D2O was found to significantly inhibit the invasion of tumor cells in a Matrigel invasion chamber assay at concentrations higher than 10% D2O. Incubation with D2O resulted in enlargement of cells, nuclear pyknosis and vacuolization, and immunostaining studies demonstrated that D2O treatment resulted in an increase in nuclear nick-end-labeling, which indicates DNA fragmentation, in KATO-3 and HepG2 cell lines. Furthermore, the nucleic acids and protein synthesis inhibition assay suggested that the inhibition of DNA synthesis may be one of the mechanisms responsible for the antitumor effects of D2O. Furthermore, oral administration of D2O resulted in a significant inhibition of the growth of Panc-1 tumor xenografted s.c. in nude mice, but survival was not prolonged. In conclusion, D2O has cytotoxic and cytostatic activities against human digestive organ cancer cell lines, and D2O may be a potential anticancer agent.

Abstract
We report an instructive case of a 65-year-old man who presented with a dumb-bell shaped tuberculous abscess across the greater sciatic notch bilaterally compressing both sciatic nerves. Clinical symptoms progressed slowly and mimicked lumbar radiculopathy, thus delaying an accurate diagnosis. Anterolateral retroperitoneal and posterolateral gluteal approaches of the greater sciatic notch as well as the acetabulum on both sides were followed in order to provide safe viewing and resection of the abscess. The abscess wall was adherent to the sciatic nerve and surrounding blood vessels. The symptoms completely disappeared after resection of the abscess.

The correlation coefficient between the ratio of the visceral adipose tissue to the subcutaneous adipose tissue (V/S) and the computed tomography (CT) number of the liver was -0.299 (P < 0.05) and that between the V/S ratio and the ratio of the CT number of the liver to that of the spleen (CT-L/CT-S) was -0.335 (P < 0.05) in the males. Partial correlation analysis after making correction for BMI showed an increased correlation coefficient of -0.485 (P < 0.05) between the V/S ratio and the CT-L/CT-S ratio in the males. The odds ratio in the males for CT-L/CT-S below 1.0 and V/S above 1.0 was 3.25 with a 95% confidence interval of 1.02 to 9.39. No such association between the V/S ratio and the CT-L/CT-S ratio was present in the female patients. Multiple regression analysis with serum level of alanine aminotransferase, a marker of fatty liver, as an independent variable revealed a partial regression coefficient of -17.7 for CT-L/CT-S (P < 0.05) in the males and -21.7 (P < 0.05) in the females, validating the CT-L/CT-S ratio as an index of fatty liver. The results indicate the association of fatty liver as determined by the CT-L/CT-S ratio with visceral obesity in males.

Abstract
While deuterium oxide (D2O) is known to produce various biological effects in living animals and cultured cells, the detailed mechanisms by which it does so remain unclear. The present study was designed to assess the effects of D2O on microfilaments (MFs) via fluorescence staining of BALB 3T3 cells and in vitro actin polymerization studies. After BALB 3T3 cells had been exposed to a concentration of more than 30% D2O for several hours, stress fibers in the peripheral region became thick and distinct, while the quantity of perinuclear MFs was drastically reduced. This effect was transient and returned to the original distribution within 12 h. Cytoplasmic F-actin (FA) also increased transiently coincident with the enhancement of stress fibers. The pattern of cell locomotion became simpler, and total locomotor activity was suppressed in a D2O concentration-dependent manner. Analysis of in vitro studies demonstrated that, when purified G-actin was polymerized in D2O at a concentration greater than 10%, the rate of actin polymerization was accelerated, whereas the total amount of polymerized actin at the steady state in D2O was the same as that in H2O controls. A gelation assay and transmission electron microscopy (TEM) showed that the network of crosslinked FA with alpha-actinin became denser in 30% D2O than in H2O. These findings concerning actin polymerization and FA gelation suggest that the alteration of stress fibers in cultured cells is caused by a direct effect of D2O on cellular MF dynamics.

Abstract
Campylobacter jejuni in chicken feces was detected by PCR and Southern blot hybridization (SBH). The detection limits of C. jejuni in chicken feces were 34,000 cells by PCR and 340 cells by SBH. Some cecal contents of chickens up to 3 weeks old were C. jejuni positive by SBH whereas all of them were negative by PCR. Two of 51 cecal contents of 18-day-old chicken embryos were C. jejuni positive by PCR and SBH; but, C. jejuni were not isolated from the samples by conventional culture with selective enrichment.

Abstract
Electrolyzed strong acid aqueous solution is acidic water that contains active oxygen and active chlorine and possesses a redox potential. We performed peritoneal and abscess lavages with an electrolyzed strong acid aqueous solution to treat 7 patients with peritonitis and intraperitoneal abscesses, who were seen in our department between December 1994 and April 1995. The underlying disease was duodenal ulcer perforation in 4 of these 7 patients and gastric ulcer perforation, acute enteritis, and intraperitoneal perforation of pyometrium in 1 patient each. Irrigation was performed twice a day. Microbiological studies of the paracentesis fluid were negative in 3 cases, and the irrigation period was 2-4 days. Anaerobic bacteria were isolated in 3 of the 4 positive cases (Bacteroides in 2, Prevotella in 1), and a fungus (Candida) was isolated in the remaining patient. The period of irrigation in these patients ranged from 9 to 12 days, but conversion to a microorganism negative state was observed in 3-7 days.

Abstract
This study was designed to assess the possibility of D2O as a therapeutic agent against human pancreatic cancer. We examined the effect of D2O on growth and invasion of human pancreatic cancer cells (Panc-1, MIA PaCa-2, BxPC-3) by using MTT assay and nude mice, on which human pancreas cancer cells were transplanted. In vitro growth of the three lines was significantly inhibited by D2O in a dose dependent manner, especially at more than a 10% concentration. Growth of Panc-1, which was transplanted in nude mice, was also inhibited by continuous oral intake of 30% D2O. Furthermore, the effect of D2O on cancer invasiveness was assessed by Matrigel invasion chamber assay. BxPC-3, which is the most adherent of the three lines, significantly reduced its invasiveness in more than 30% D2O media. In addition, the present study also demonstrated the inhibition of cancer cell locomotion by D2O in phagocytokinetic analysis. In conclusion, D2O may be applied for the therapeutic use against pancreatic cancer.

Abstract
Eighty-four patients were examined for blood coagulability during the acute phase of Bell's palsy. Abnormally high levels of thrombin-antithrombin III complex (TAT) and alpha-2 plasmin inhibitor-plasmin complex (PIC) were found, with these increases statistically significant. Values tended to be higher in patients within 3 days after occurrence of the palsy when compared to values in patients 4 days or more later. Abnormal TAT and PIC levels in the acute phase then tended to become normalized during the convalescent phase of the disease. These findings indicated that activation of intravascular coagulability had occurred, with patients entering a temporary clot-forming state. Among the several hypotheses for the etiology of Bell's palsy, our findings support a circulation disorder as an influential factor.

Abstract
It has been reported that subcutaneous administration of pancuronium produces prolonged neuromuscular blockade. The purpose of this study was to evaluate the antagonistic effect of neostigmine on neuromuscular blockade following subcutaneous injection of pancuronium in anesthetized patients. Fourteen male patients aged 32-67 yr, weighing 50-58 kg, and scheduled for surgical operation lasting more than 6 hr were included in the study. None of the patients had paresis. Anesthesia was induced with thiamylal and SCC. Patients under N2O-oxygen-enflurane (1.0-1.5%) anesthesia, were divided into two groups (n = 7 in each group). Group A was given an intravenous bolus of pancuronium 6 mg. Group B received pancuronium 6 mg subcutaneously in the ankle. Train-of-four responses were evaluated every 12s by measuring the force of thumb adduction produced in response to supramaximal stimulation of the ulnar nerve at the wrist. When the train-of-four ratios recovered to approximately 0.2 in groups A and B, a mixture of neostigmine 1.0 mg and atropine 0.5 mg was administered. The onset of fade in train-of-four responses was significantly more rapid in group A (intravenous administration) than in group B (subcutaneous administration). Time intervals to maximum train-of-four depression from pancuronium administration in groups A and B averaged 2.6 and 125.4 min, respectively. No significant differences in the recovery times of the train-of-four ratios from 0.2 to 0.7 following neostigmine administration in groups A and B were demonstrated. None of the patients who received pancuronium subcutaneously showed recurarization following neostigmine administration.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
An immunohistochemical investigation was conducted on infiltrating lymphocytes in submandibular glands removed from three cases with unspecific chronic sclerosing sialadenitis of the submandibular gland (unspecific CSSS) which has been described for the first time by Küttner. A high degree of lymphocyte infiltration was recognized and formation of lymphatic follicles was observed. In particular, activated B cells were predominantly observed in that part of the lymphatic follicles which was equivalent to germinal centers. In the T cell subset, the helper/inducer T cells displayed significant dominance over suppressor/cytotoxic T cells, and were distributed in the dark peripheral zone of the follicles. The distribution pattern of these lymphocytes seemed to be similar to antigenically stimulated lymph nodes and it was recognized that the unspecific CSSS could be a site of exceedingly active local immune responses. The authors believe that these findings support the view that unspecific CSSS (Küttner tumor) is an immune disorder.

Abstract
Using male Wister rats, the ornithine decarboxylase (ODC) activity in the fundic mucosa has been determined from the duodenal juice with bile of a reflux model. The activity at 24 hours postoperatively presented a value approximately 18 times higher than the preoperative level. Though this level declined subsequently, it still was approximately two times higher four weeks later. The ODC activity in the corporal mucosa of humans was compared in 25 normal persons, in 21 patients with a gastric adenoma in 29 patients with a gastric cancer, in 20 patients who had undergone a Billroth I operation and in 20 patients who had undergone a Billroth II operation. No differences in ODC activity were observed among those with a gastric adenoma, a gastric cancer, and normal cases but significantly higher values were seen in cases with a remnant stomach, particularly those who had undergone Billroth II reconstructive surgery. Further, this activity tended to be especially high from 5 to 15 years postoperatively in cases with a gastric remnant.

Abstract
We have measured the serum erythropoietin concentrations in 14 patients with liver cirrhosis and in 14 patients with a hepatocellular carcinoma. Among these patients, 2 with liver cirrhosis (14.3%) and 7 with a hepatocellular carcinoma (50.0%) were found to have raised serum erythropoietin concentrations, ranging up to 40 mU/ml. Negative correlations were found between erythropoietin and the RBC, and the Hb and Ht in the cases with liver cirrhosis. In contrast, a positive correlation which was not significant was found only between the erythropoietin and the RBC in cases involving a hepatocellular carcinoma. This has suggested that the relationship between the erythropoietin and the RBC in cases of a hepatocellular carcinoma differs from the relationship seen under the usual physiological circumstances of those with liver cirrhosis.

Abstract
A 51-yr-old male patient with Cushing's syndrome due to huge nodular adrenocortical hyperplasia is described. Urinary 17-OHCS was not suppressed by a high dose of (8 mg) dexamethasone and showed rather a tendency to paradoxical response. There was no response to metyrapone. Plasma cortisol showed a hyperresponse to insulin-induced hypoglycemia and a rapid response to corticotropin releasing hormone-lysine vasopressin (CRH-LVP) administration without an obvious ACTH response. Plasma cortisol responded to synthetic ACTH. Urinary 17-OHCS did not show parallel changes with plasma cortisol. These results and computerized tomography data suggested huge multiple nodular adrenocortical hyperplasia, which was confirmed later by surgery. The left and right adrenal glands weighed 105 and 45 g, respectively. Hyper-reaction of the adrenal gland to a small change in plasma ACTH or "unknown factors" may cause not only the discrepancy between cortisol and ACTH response but also the development of autonomous nodules in the adrenal gland.

Abstract
An analysis of 242 patients with a hepatocellular carcinoma (HCC) has shown that 65 patients without a hepatitis B virus (HBV), alcohol abuse, or a transfusion history and 17 posttransfusion patients had a mean death age of 65.5 +/- 10.2 and 62.1 +/- 8.4 years respectively. The average age of 65 patients was 8.5 years older than those with a HBV and without a alcohol abuse history. Of 17 patients, 3 with a HBV had a mean death age of 55.3 +/- 10.8 years and the interval time from transfusion to a HCC was significantly shorter than in other post-transfusion patients.

Abstract
A case of adult neuroblastoma of the right adrenal with tumor thrombus extending into the right atrium is reported. Because of right heart failure, the tumor thrombus in the right atrium was removed under the cardiopulmonary bypass. The histopathological examination of the tumor thrombus revealed neuroblastoma. Fourteen days after the first operation, the adrenal tumor, right kidney and tumor thrombus remaining in the vena cava were removed to prevent the recurrence of right heart failure. Two courses of chemotherapy and radiation were given postoperatively and the patient was doing well. Eight months after the second operation, however, the patient died of multiple metastases of the bone and liver.

Abstract
A 51-yr-old male patient with a 3 yr history of Cushing's syndrome is described. The baseline plasma cortisol level was elevated, while the plasma ACTH levels remained at an undetectable level. Dynamic testing of pituitary-adrenal function revealed no suppression after 8 mg of dexamethasone, and there was no response to metyrapone or CRF, while plasma cortisol showed a hyperresponse to synthetic ACTH. Plasma cortisol responded to insulin-induced hypoglycemia without an obvious ACTH response. These and the computerized tomography data suggested a "huge" bilateral nodular adrenocortical hyperplasia which was later confirmed by surgery. The left and right adrenal glands weighed 55 and 76 g, respectively. In vitro experiments, using the adrenal tissue, showed that there was an adrenal cortisol response to 1-39 ACTH but not to regular insulin, arginine vasopressin, angiotensin II, norepinephrine or epinephrine. These results indicate that plasma cortisol responded to a slight hypoglycemia-induced plasma ACTH change which was not detected in the ACTH radioimmunoassay or to factors other than ACTH which might be induced by hypoglycemia.

Abstract
Chemical analyses by atomic absorption spectrophotometry and crystallographic studies by the X-ray powder diffraction method and infrared spectrometry (KBr-disk method) were made on 33 cases of calcium carbonate gallstone or so-called limy bile. Chemically, calcium carbonate was the major constituent, ranged from 33.7 to 91.6% and averaged 77.8%. Crystallographically, calcium carbonate has three different polymorphic crystalline forms; calcite, aragonite and vaterite. In nature the most stable calcite (hexagonal) is most commonly found and aragonite (rhombic) is next. On the other hand vaterite, which is unstable hexagonal modification, rarely occurs in biological systems. But in our gallstone series in man, aragonite was most commonly found, with an occurrence rate of 90.6%, while that of calcite was 62.5%. Even vaterite was found in 28.1%. Moreover three cases contained all three forms of calcium carbonate polymorphs; calcite, aragonite and vaterite. This was a very unusual condition. Some environmental factors controlling the growth of these crystals, such as specificity of the bile, are suggested.
