Abstract
BACKGROUND The effect of splenomegaly in patients with liver cirrhosis and portal hypertension is not fully understood. This study was designed to determine the effect of laparoscopic splenectomy on portal haemodynamics in these patients. METHODS Patients with liver cirrhosis and portal hypertension who underwent laparoscopic splenectomy in Kyushu University Hospital from January 2006 to March 2009 were evaluated retrospectively. Correlations between splenic size and portal haemodynamics, and changes in portal haemodynamics and in levels of the vasoactive agents endothelin (ET) 1 and nitric oxide metabolites (NOx) before and 7-10 days after laparoscopic splenectomy were analysed. RESULTS Portal venous (PV) blood flow, PV cross-sectional area and PV congestion index correlated significantly with splenic size (P < 0·050). All three were significantly reduced following splenectomy in 59 patients. The hepatic venous pressure gradient, measured in 18 patients, decreased by 25 per cent after splenectomy (P < 0·001). Portal vascular resistance was also reduced, by 21 per cent (P = 0·009). The peripheral blood concentration of ET-1 decreased from 2·95 to 2·11 pg/ml (P < 0·001), and that of NOx tended to decrease (from 29·2 to 25·0 pg/ml; P = 0·068). In hepatic venous blood, the level of ET-1 decreased from 2·37 to 1·83 pg/ml (P = 0·006), whereas NOx concentration tended to increase (from 24·5 to 30·9 pg/ml; P = 0·067). CONCLUSION In patients with liver cirrhosis and portal hypertension, splenectomy reduced portal venous pressure. A decrease in splanchnic blood flow, by eliminating splenic blood flow, and reduction in intrahepatic vascular resistance, by normalizing hepatic concentrations of ET-1 and NOx, may both have contributed.

Abstract
Dysfunction of T cells is a common feature in chronic persistent viral infections, including hepatitis C virus (HCV), and although hepatic and peripheral T cells have been studied extensively in chronic HCV hepatitis, the role of splenic T cell responses in such patients is poorly defined. This is an important issue, as thrombocytopenia is a complication of HCV-related liver cirrhosis (LC), due to splenic platelet sequestration and bone marrow suppression; splenectomy has been proposed to treat such patients. Herein, we studied peripheral blood mononuclear cells (PBMC) and splenic lymphoid subpopulations from a total of 22 patients, including 15 with HCV-related LC with marked thrombocytopenia treated with splenectomy, and seven controls. CD4(+) T cells from peripheral blood and spleen were isolated and phenotype and function evaluated. Splenic CD4(+) T cells in patients with LC expressed molecules associated with inhibitory signalling, including increased frequency of negative markers such as cytotoxic T lymphocyte associated antigen-4 (CTLA-4) and programmed death 1 (PD-1) and decreased production of cytokines. Patients with LC manifest higher levels of splenic CD4(+) regulatory T cells and PD-L1- and PD-L2-expressing cells than controls. Blocking of PD-1/PD-1 ligand interaction reconstituted proliferative and cytokine responses of splenic mononuclear cells (SMC) from patients with LC. Splenectomy was followed by an increase in the ratio of interferon (IFN)-γ to interleukin (IL)-10 and a reduction of PD-1-expressing CD4(+) T cells in peripheral blood. Our data suggest that peripheral tolerance is promoted by the spleen in LC via the up-regulated expression of PD-1 ligands.

Abstract
BACKGROUND Laparoscopic surgery has continued to gain popularity in almost all fields of abdominal surgery, and robotic systems have been introduced in general surgery. Naviot is a new remote-controlled laparoscope manipulator system controlled by the operator's hand. This study assessed its introduction into clinical practice. METHODS A group of 10 consecutive patients with cholelithiasis underwent laparoscopic cholecystectomy assisted by the Naviot system (Naviot group). Another group of 41 patients who underwent laparoscopic cholecystectomy with a conventional human camera holder (human camera group) were selected for a comparison of their operative results with those of the Naviot group. RESULTS The operative time of 89.3 +/- 27.1 min for the Naviot group was significantly longer than that of 74.8 +/- 28.1 min for the human camera group (p < 0.05). However, when the setup time for the Naviot system was excluded, the operative time was not significantly different from that for the human camera group. Other operative results showed no significant difference between the two groups. CONCLUSIONS The authors believe that the new Naviot system is feasible for clinical use, and that it enables surgeons to perform solo gastrointestinal surgery.

Abstract
Mice were given the extract of cultured Cordyceps sinensis (Cs) (200 mg/kg daily, p.o.) for 3 weeks. In vivo phosphorus-31 nuclear magnetic resonance (NMR) spectra of the liver were acquired at weekly intervals using a surface coil. From 1 to 3 weeks, a consistent increase in the ATP/inorganic phosphate ratio, which represents the high energy state, was observed in the Cs extract-treated mice. The intracellular pH of the Cs extract-treated mice was not significantly different from that of the control mice. No steatosis, necrosis, inflammation or fibrosis were observed in the liver specimens from Cs extract-treated mice.

Abstract
A 7-year and 11 month-old girl with cerebellar astrocytoma linked to familial ataxia-telangiectasia (AT) is presented. She was born as the 7th girl of a woman with aortic arch syndrome. Two elder sisters of the patient have ataxia telangiectasia. She had immunodeficiency, and cerebellar ataxia, but had no oculocutaneous telangiectasia. The risk of cancer developing in AT patients is about 1,200 times greater than that in age-matched controls. With regard to central nervous system tumours, seven primary tumours have been reported, such as 3 cases of medulloblastoma and 4 cases of glioma. Members of AT families who were under the age of 45 had a risk of dying of a malignant neoplasm five times greater than in the general population. However, there were no reports of glioma in AT families. In this case, it is suggested that IgA deficiency linked to familial AT may have contributed to the development of astrocytoma.

Abstract
Cardiovascular effects of the crowns-of-thorns starfish (Acanthaster planci) venom were examined in rats. The crude venom extracted from the spines of A. planci caused systemic hypotension associated with an increase in heart rate and a decrease in renal cortical blood flow when given i.v. The hypotensive effect of the venom was not inhibited by pretreatment with atropine, indomethacin or aprotinin, but was significantly inhibited by SRI 63-441, a platelet activating factor (PAF) antagonist. The venom caused dose-dependent vasorelaxation of the isolated rat aortic ring preparation precontracted by noradrenaline, an effect which was significantly attenuated by pretreatment with SRI 63-441, methylene blue or parabromophenacyl bromide. Denudation of the endothelium also diminished the vasorelaxing effect of the venom. Both the vasorelaxing and the hypotensive effects showed tachyphylaxis. These results suggest the release of PAF or a PAF-like substance from the endothelium by the venom.

Abstract
Okinawa Prefecture is an endemic area of Strongyloides stercoralis infection. Since treatment of this infection remains unsatisfactory, we evaluated the efficacy of ivermectin. Twenty-three patients were treated with a single oral dose of ivermectin (mean +/- SD, 105.5 +/- 20.8 mcg/kg of body weight), followed by a second dose two weeks later. The rate of cure was 85.7% at 2 weeks after the first treatment, and 90.5% at 2 weeks after the second treatment. Side effects occurred in 2 patients (8.7%), but they were mild and transient. The results indicate that ivermectin might be useful and relatively safe for the therapy of Strongyloides stercoralis infection as an alternative to thiabendazole or mebendazole.

Abstract
Eleven cases of chronic subdural hematoma (CSH) secondary to coagulopathy were experienced in our department in the last 5 years. They were classified into 4 groups, I: secondary to diffuse metastatic carcinomatosis of the bone marrow (4 cases), II: malignant hematological disease (acute lymphocytic leukemia and myelodysplastic syndrome 1 case each), III: postreplacement of cardiac valves or vein graft having been treated with anticoagulants (warfarin) (3 cases) and IV: chronic renal failure after having been hemodialyzed (2 cases). The outcomes were all good in group III, and there was one good outcome in group IV. However, death was the outcome in all the other cases. Conservative treatment (mannitol and steroid for 2 weeks) was carried out in 4 cases, all of which improved clinically with diminished hematoma. In 9 cases, surgical treatment was attempted by means of burr hole irrigation of the hematoma. Two of them developed intracerebral hematoma, and one developed acute brain swelling. In conclusion, treatment of CSH secondary to coagulopathy should be selected as follows. 1. Conservative treatment is to be the first choice, if conditions allow it. 2. Surgery can be performed by burr hole irrigation when indicated. Precautions should be taken not to injure the inner membrane of the hematoma or the brain proper, and the need for slow decompression should be kept in mind.

Abstract
A 49-year-old male patient was admitted to Ryukyu University Hospital complaining chiefly of progressive loss of mental activity for one year. He had a history of head trauma at the right retromastoid region when he was 24. Generalized convulsions developed three years later, and left exophthalmos, facial varix and impairment of visual acuity developed seven years later. Dural arteriovenous fistula of the posterior fossa was diagnosed at the age of 32, and feeding EC and tentorial arteries were successively ligated on the right several times without any effect. Angiography during this admission revealed tremendous collateral flows; a marked dilated tortuous occipital artery fed from the right vertebral artery, meningeal branches of VA and PICA, the marginal tentorial artery, and the posterior temporal artery from MCA, PCA were drained into the right transverse sinus. But transverse sinuses were occluded bilaterally, and venous outflows were directed to the superior sagittal sinus retrograde via the ascending cortical vein, Trolard veins, and sphenoparietal and cavernous sinuses. The final drainer was the superior ophthalmic vein on the left. Normal deep veins were not visible. In park bench position, the nidus was totally resected with a part of the transverse and thrombosed sigmoid sinus. Postoperative course was uneventful, and an angiogram showed complete disappearance of the AVF. Dural AVG in the posterior fossa with characteristics such as high flow, and which is rich in collaterals following palliative treatment indicates that total surgical resection should be undertaken.

Abstract
We previously treated 47 patients with 100 mg of mebendazole (MBZ) twice a day by oral use for 5 days and this treatment was repeated 1, 3 and 4 weeks later. Although the cure rate was 100%, liver injury was observed in 48.9% of the patients. On this study, we reduced the periods of administration of MBZ (powder; 100 mg twice a day) to 4 days, and repeated it once after 3 days interval, and this initial treatment was performed one more time after 10 days interval (group 1). As Strongyloides stercoralis is mainly located in upper digestive systems, we used the drug reduced to powder for the purpose of better contact with the parasites. We considered that the powder should be absorbed well and liver injury occurred in high incidence. As group 2, we used the tablet itself in the same schedules of group 1. The results obtained were as follows; 1) The eradication rates at 10 days after the initial treatment were 97.8% (44 of 45 patients) in group 1 (powder) and 93.0% (40/43) in group 2 (tablet). 2) At 3 days after the whole treatment, the eradication rates were 100.0% in group 1, and 97.7% (42/43) in group 2. 3) Slight side effects such as constipation (6.7% in the group 1), dizziness or vertigo (6.7% in the group 1) and itching (6.7% in the group 2) were observed. 4) Liver injury was observed at 11.1% (5/45) 10 days after the initial treatment in the group 1 and 13.3% (6/45) in the group 2.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The acute regional hemodynamic effects of spirapril diacid, a novel nonsulfhydryl angiotensin-converting enzyme inhibitor, and enalapril diacid at an equidepressor dose were examined in anesthetized dogs by simultaneously measuring renal, coronary, vertebral arterial and aortic blood flow. Spirapril diacid (30 micrograms/kg, i.v.) lowered aortic pressure and increased aortic and renal blood flow associated with no marked change in heart rate, myocardial contractility, vertebral and coronary blood flow in a similar manner to enalapril diacid (30 micrograms/kg, i.v.). Both inhibitors thus produced an increase in stroke volume and a decrease of the rate-pressure product. The decrease of renal vascular resistance after administration of both agents was greater than that in vertebral and coronary vascular beds. A relatively more prolonged renal vasodilatation and a shortened coronary vasodilatation were seen with spirapril diacid as compared with enalapril diacid, despite practically identical reductions in total peripheral resistance. Each of the drugs markedly inhibited the pressor and renal vasoconstrictor responses to angiotensin I. These results indicate that the two inhibitors exhibit a similar profile of regional differences in vasodilatory effects, although they might display different durations of regional vasodilatation.

Abstract
Following injections of retrograde tracers into the spinal cord enlargements, the mesencephalic locomotor region (MLR) was electrically stimulated to induce locomotion in decerebrate rats. MLR sites coincided with cholinergic pedunculopontine nucleus (PPN) neurons, which were selectively labelled using NADPH diaphorase histochemistry. Retrogradely labelled (spinal-projecting) PPN neurons were scattered among cholinergic PPN neurons. The absence of retrogradely labelled, NADPH diaphorase positive PPN neurons indicates that spinal enlargement projections are non-cholinergic.

Abstract
Retrograde tracers were injected into the rat medioventral medulla (MED) and the injection site was identified as a locomotion- inducing area by electrical stimulation in the decerebrate preparation. Histological reconstructions showed that about 10% of cholinergic pedunculopontine (PPN) and laterodorsal tegmental (LDT) neurons project to the MED. Also, large numbers of non-cholinergic cells in and around the PPN and LDT were found to project to the MED.

Abstract
The effects of superoxide dismutase modified with polyoxyethylene (SOD-POE) on impairment of myocardial segment shortening (SS) during coronary stenosis plus pacing-induced tachycardia (CSPT) and the recovery after reperfusion was examined in anesthetized dogs. SOD-POE or saline was administered i.v. 30 min before reperfusion. Changes in hemodynamic variables and SS by CSPT were similar in both groups. However, the SOD-POE group showed improved recovery of SS compared with the control group. Results indicate that oxygen-derived free radicals may partially be involved in the genesis of myocardial dysfunction after CSPT-induced regional ischemia.

Abstract
Characteristics of the cardiovascular effects of habu venom were studied in vivo and in vitro in rats. Aortic pressure (AoP), heart rate (HR) and renal cortical blood flow (RCBF) assessed by a laser-Doppler flowmeter were measured in anesthetized rats. Administration of habu venom (0.2-1.6 mg/kg, i.v.) dose-dependently produced a fall in AoP without a marked change in HR. RCBF decreased significantly along with the decline in AoP. Heated habu venom (70 degrees C for 5 min) or the residual venom by dialysis produced similar hemodynamic responses to nonheated crude habu venom. Although habu antivenin significantly reduced the effects of habu venom, indomethacin, aprotinin, atropine, captopril and chlorpheniramine did not. Methylprednisolone significantly attenuated these effects. Habu venom (10(-5) to 3 x 10(-4) g/ml) produced dose-dependent relaxations of the isolated rat aorta preparations precontracted with norepinephrine or KCl, which were not affected by indomethacin, nordihydroguaiaretic acid, p-bromophenacyl bromide, mepacrine, methylene blue or de-endothelialization. These results indicate that habu venom, particularly its heat-stable component(s) which has at least more than 10,000 molecular weight, produces hypotensive and vasorelaxant effects in rats, and suggest that eicosanoids, kinins, histamine, ACh, and endothelium are scarcely involved in these effects.

Abstract
Effects of arotinolol, a combined alpha- and beta-adrenoceptor blocking agent, on regional myocardial dysfunction produced by severe coronary stenosis in anesthetized dogs were examined and compared with those of labetalol and propranolol. Doses of these three antagonists were selected to produce a comparable degree of the negative chrono- and inotropic effect but a different potency of alpha-adrenoceptor blockade (labetalol greater than arotinolol). Regional myocardial function measured as segment shortening (%SS) was decreased to around 2-3% by constriction of the left circumflex coronary artery (LCX), and then drug or saline was administered i.v. The stenosis of LCX was released 30 min after the administration. No significant alteration in hemodynamic and contractility parameters was seen as compared to the predrug value up to at least 30 min after saline i.v. Arotinolol and propranolol both reduced heart rate and peak positive left ventricular dP/dt (LVdP/dt) without a significant change in LCX flow. Concomitantly, %SS distal to a coronary stenosis was significantly improved by arotinolol and propranolol. On the other hand, labetalol significantly reduced LCX flow probably due to systemic hypotension and failed to improve %SS in the ischemic area, although the agent markedly decreased heart rate and LVdP/dt. These results indicate that arotinolol improves impaired regional myocardial function distal to a coronary stenosis in a similar manner with propranolol.

Abstract
Previous anatomical studies demonstrated the presence of descending projections from the physiologically identified mesencephalic locomotor region (MLR) to the medioventral medulla (MED) in the cat. The present experiments were designed to determine if a similar low threshold locomotion-inducing area is present in the rat medulla. In addition, the nature of the neurochemical control of this area of the brain was explored using localized injections of neurochemical agents in the decerebrate rat during locomotion on a treadmill. A region virtually identical to that reported in the cat was found to lead to controlled locomotion on a treadmill following stimulation at low amplitude currents (less than or equal to 60 microA). Injections of cholinergic agonists into the MED of the rat induced locomotion which could be blocked by injections of cholinergic antagonists. In addition, injections of GABA antagonists were found to induce stepping which could be blocked by injections of GABA or GABA agonists. Substance P (SP) also was found to induce walking following injection into the MED of the rat. Injections of an excitatory amino acid agonist (NMDA) also were found to induce locomotion in the rat. These effects were blocked by injections of an excitatory amino acid antagonist (APV). Since these results had not been reported for the cat MED, a short series of experiments revealed that the MED in the cat also responded to NMDA.

Abstract
The purpose of this study was to determine the nature of the neurochemical signals which impinge on the mesencephalic locomotor region (MLR) to produce locomotion in the rat. Injections of GABA antagonists into NADPH diaphorase-positive regions (PPN) were found to induce locomotion for short episodes (5-30 sec) which were repeated for several minutes (1-40 min). Such activity was blocked by injections of GABA and the GABA agonist, muscimol. Locomotion was induced by injection of substance P (SP), which also produced short, repeated episodes of locomotion. The more potent excitatory amino acid agonist, n-methyl-d-aspartic acid (NMDA), however, did produce dose-dependent, long-lasting (20 sec-5 min) locomotor episodes which were repeated over prolonged periods at the higher concentrations used (2-24 min). Additional injections of NMDA could drive stepping from a walk to a trot to a gallop. The effects of NMDA were blocked by injections of the excitatory amino acid antagonist, aminophosphonovalerionic acid (APV) (1-10 mM). Preliminary evidence suggests that carbachol (10-50 mM), a cholinergic agonist, inhibits NMDA-induced increases in muscle tone and episodes of stepping. The effect of carbachol was blocked by the cholinergic antagonist, atropine.

Abstract
Retrograde transport of fluorescent tracers and nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) histochemical techniques were combined in a study of septohippocampal projections in the rat. The dorsal (DH) and ventral (VH) hippocampus were simultaneously injected with different tracers (Fast Blue or Fluoro-Gold). Histochemical procedures revealed many NADPH-d positive cells located in the medial septum and the horizontal limb of the diagonal band. In the medial septum, NADPH-d positive neurons were mostly located lateral to the midline region and some of these were double-labeled by the tracer injected into the VH. Also, NADPH-d positive cells were found in the horizontal diagonal band and some of these were double-labeled following injections into the DH. No fluorescence/NADPH-d double-labeled neurons were observed in other structures known to project to the hippocampus.

Abstract
Vasodilating effects of dipyridamole were compared with those of papaverine in anesthetized open-chest dogs. Dipyridamole i.v. produced a significant fall in aortic blood pressure and significant increases in aortic and coronary blood flows. Vertebral blood flow did not alter, but renal blood flow was transiently decreased. Left ventricular dP/dt, heart rate and left ventricular enddiastolic pressure were hardly affected by dipyridamole. Papaverine i.v. significantly increased aortic, vertebral and coronary blood flows, left ventricular dP/dt and heart rate and significantly decreased aortic blood pressure and left ventricular enddiastolic pressure. Renal blood flow was instantly decreased by papaverine. Percent change in each vascular resistance showed decreases in total peripheral, vertebral and coronary vascular resistances in response to both drugs, and the decrease in coronary vascular resistance was the most remarkable. Renal vascular resistance was increased by dipyridamole, while it was decreased by papaverine. Percent change in double product (heart rate x systolic arterial blood pressure) showed a monophasic decrease pattern with dipyridamole and a biphasic pattern with an initial, transient decrease followed by an increase with papaverine. The present results indicate that dipyridamole and papaverine produce marked coronary vasodilatation, and that papaverine is different from dipyridamole in cardiotonic properties.

Abstract
To identify the origin of a small inserted segment in a de novo 8p+ chromosome, an originally programmed computerized database for chromosomal aberration syndromes was utilized. The system selected 3q2 trisomy and 10q2 trisomy as candidates. As a result of a careful comparison of several high-resolution banding patterns among chromosomes 3, 10 and the inserted segment, her karyotype was disignated as: 46,XX,-8,+der(8), inv ins(8;3)(p21.1;q26.32q24) de novo. A small segment from 3q24 to 3q26.32 was trisomic, and invertedly inserted into the short arm of chromosome 8. This computerized database was considered to be useful for analyses of the small de novo inserted chromosomal segment.

Abstract
Cardiovascular effects of the new calcium antagonist, isradipine (PN 200-110), were compared with those of diltiazem in anesthetized open-chest dogs. Isradipine 5 micrograms/kg i.v. produced significant decreases in systolic, diastolic and mean aortic blood pressure (AoP) concomitant with a decrease in mean renal blood flow (RBF) and increases in mean vertebral blood flow (VBF), mean coronary blood flow (CBF) and left ventricular dP/dt (LVdP/dt), but almost unchanged heart rate (HR) and left ventricular enddiastolic pressure (LVEDP). Diltiazem 300 micrograms/kg i.v. also produced decreases in AoP and RBF and increases in AoF, VBF and CBF. LVdP/dt and LVEDP were not significantly changed, but HR was decreased by this drug. Duration of increase in AoF, VBF and CBF was significantly longer in isradipine than in diltiazem. The decrease of coronary vascular resistance relative to total peripheral resistance was significantly greater than 1.0 for diltiazem, but not for isradipine. Results indicate that isradipine produces effects on AoP, AoF, VBF, CBF, RBF and LVEDP similar to diltiazem and the drug increases LVdP/dt without a decrease in HR in contrast to diltiazem, and that the effects of isradipine were long sustained when compared with those of diltiazem.

Abstract
Fast blue and Rhodamine microspheres were used to analyze the topography and collateralization of the limbic nuclei of the thalamus to 4 defined areas of the cingulate gyrus (anterior 24, posterior 24, anterior 29, and posterior 29). The anterodorsal nucleus and the anteroventral nucleus project to posterior area 24 and all of area 29. The anteromedial nucleus projects generally to both areas 24 and 29, but principally to anterior area 24. The laterodorsal nucleus projects only to area 29. The anterior and posterior portions of the thalamic nuclei topographically project to the anterior and posterior regions of the cingulate gyrus, respectively. Neurons in the medial region of the anterior nuclei project to the anterior area of the cingulate gyrus while neurons located in the lateral region project to posterior areas. Collaterals (9-13%) from the anteromedial nucleus project diffusely to areas 24 and 29, while collaterals from other nuclei project primarily to areas adjacent to each other. Modulation of limbic system functions probably occurs via these projection fibers. Furthermore, the idea appears to be reinforced that at least a dual and coupled function exists for these direct thalamocingulate connections.
