Role of Phage Shock Protein in Recovery of Heat-injured Salmonella.

　Sublethally heat-injured cells of Salmonella in food can recover under favorable conditions, leading to foodborne illness. To elucidate the molecular mechanism of recovery from heat injury, the global changes in gene transcription of Salmonella Typhimurium were investigated in previous study. In this study, the functions of genes involved in phage shock response (viz.

Relationship between the Carotid Plaque T1 Relaxation Time and the Plaque-to-Muscle Signal Intensity Ratio on Black-Blood Magnetic Resonance Imaging Scans.

Background: Black-blood magnetic resonance imaging (BB-MRI) is useful for the characterization and assessment of carotid artery plaques. The plaque-to-muscle signal intensity (SI) ratio (plaque/muscle ratio [PMR]) is used widely to evaluate plaques. However, the correlation between the PMR and the T1 relaxation time needs to be determined.

Changes in transcription during recovery from heat injury in Salmonella typhimurium and effects of BCAA on recovery.

Mechanisms of recovery from heat injury in Salmonella typhimurium were elucidated. Recovery of the heat-injured S. typhimurium cells in TSB resulted in full recovery after 3 h of incubation at 37°C.

Successful steroid pulse therapy for brain lesion caused by Shiga toxin 2 in rabbits.

Betamethasone sodium phosphate (BSP) is usually used as a steroid therapy for human brain edema. High doses of BSP (36mg/kg) twice a day for two days statistically reduced the mortality rate and improved the survival period of Stx2 (1.4mug/kg; 1.

[Case report of traumatic hemorrhage from the anterior choroidal artery].

Traumatic hemorrhage from the anterior choroidal artery is very rare. A 74-year-old male was admitted to our hospital immediately after a traffic accident. CT on admission showed right intracerebral hematomas in the posterior limb of the internal capsule and the upper part of the right cerebral peduncle.

[Isolated trigeminal sensory neuropathy due to pontine infarction of the root entry zone--report of two cases].

Secondary trigeminal neuralgia and isolated trigeminal neuropathy due to ischemic lesion of the pons are very rare. We report 2 patients with pontine infarct transecting the central trigeminal pathways resulting in trigeminal neuropathy and/or neuralgia. Case 1: A 48-year-old female presented with lancinating pain and paresthesia and hypesthesia in the right V2 and V3 distributions.

[Rapid disappearance of acute epidural hematoma by percutaneous aspiration of subperiosteal hematoma--case report].

We present the case of an 8-year-old boy who was injured in a bicycle accident and was admitted with a right frontal skull fracture, an acute epidural hematoma, a right frontal laceration, and a subperiosteal hematoma on admission. After the frontal cutaneous suture, the subperiosteal hematoma was aspirated by the percutaneous needle. Two hours later, a CT scan revealed that the epidural hematoma was disappeared.

[Conjugate deviation in ischemia of medial medullary oblongata--report of three cases].

Medial medullary infarct (MMI) is a rare type of brain stem infarction. Its clinical picture was characterized by contralateral hemiparesis, deep sensory disturbance, and ipsilateral hypoglossal paresis, but conjugate deviation or nystagmus is uncommon as initial symptom. Case 1: A 73-year-old man developed vomiting and vertigo.

Neuronal damage in hydrocephalus and its restoration by shunt insertion in experimental hydrocephalus: a study involving the neurofilament-immunostaining method.

Object: The morphological and functional impairments of neurons and their connections caused by hydrocephalus, and their restoration by ventricular shunt placement were investigated in experimental hydrocephalus by the immunostaining of neurofilaments, which constitute the major component of the neuronal cytoskeleton.

Methods: Progressive hydrocephalus was induced in 15 young mongrel dogs 1 to 2 months of age, 3 to 4 weeks after cisternal injection of kaolin. The dogs were divided into three groups of five animals each, a "preshunt," "post-shunt," and "nonshunt" group, depending on whether the hydrocephalic animals underwent a procedure to insert a ventriculoperitoneal shunt.

Magnetic resonance for evaluation of toxic encephalopathies: implications from animal experiments.

Examinations of brain of rats intoxicated with hexachlorophene or acrylamide with ultrahigh-field (4.7 T) proton magnetic resonance (MR) showed alterations consistent with clinical pictures in humans and morphological findings in experimental animals. On the other hand, conventional biochemical analyses have revealed that ethylene oxide, methyl bromide, and acrylamide inhibit creatine kinase (CK; an enzyme catalyzing the reaction: ATP+creatine<-->ADP+phosphocreatine) activities in the brain of animals.

[Evaluation of the vocal tract during Japanese vowel production in myasthenia gravis using magnetic resonance imaging].

We report a 65-year-old Japanese female whose primary symptom of myasthenia gravis was related to rhinolalia aperta. The vocal tract during vowel production was evaluated using two-dimensional fast advanced spin echo (2D-FASE) MR images on supine and prone position. Before treatment, MRI on prone position demonstrated anterior shift of the palatine uvula and the tongue during Japanese "a", "u" and "o" production following the gravity, the former suggested the paresis of the sphenosalpingostaphylinus and elevator veli palatini muscle and the latter the paresis of the styloglossal and hypoglossal muscles.

[Delayed epidural bleeding caused by traumatic pseudoaneurysm of the middle meningeal artery: case report].

A 16-year-old man who presented with delayed bleeding of epidural hematoma is reported. Computed tomography (CT) on admission demonstrated a small amount of right epidural hematoma and a small fracture of the right lateral orbital wall. He was treated conservatively.

[Case report of Rosai-Dorfman disease mimicking pachymeningitis].

Rosai-Dorfman disease (RDD) is a rare idiopathic histioproliferative disease affecting the lymph nodes. Extranodal sites may be involved and occasionally represent the initial or sole manifestation of the disease. Central nervous system manifestations especially are exceedingly rare.

Preoperative evaluation of trigeminal neuralgia due to epidermoid tumor using a three dimensional fast advanced spin echo--case report.

We report preoperative virtual images reconstructed from three-dimensional fast advanced spin echo (3D-FASE)and evaluate the cause of a trigeminal neuralgia due to an epidermoid tumor. A 60-year-old man had a 3-year-history of atypical trigeminal neuralgia in the left V2 region accompanied by a hypesthesia in the cheek. Neuroimaging demonstrated an epidermoid tumor in the left cerebello-pontine cistern.

[Rapid improvement of callosal edema by thiamine administration in Marchiafava-Bignami disease: a case report].

Marchiafava-Bignami disease (MBD) associated with chronic alcoholism is a fatal disorder characterized by demyelination of the corpus callosum. A 62-year-old Japanese man, a heavy drinker for his last over 10 years, was admitted to our hospital because of acute onset of speech disturbance. The first MR images showed abnormal signal intensity of the corpus callosum, which was a typical finding of MBD, but no signal abnormality on diffusion-weighted images.

[Paradoxical worsening ocular movement in idiopathic carotid-cavernous fistula without conjunctival congestion--case report].

We report a case of carotid-cavernous fistula(CCF) without conjunctival congestion and showing radiographically paradoxical worsening ocular movement. A 71-year-old woman suffered from mild double vision. The first carotid angiogram revealed left CCF, which was supplied by dural branches of the internal and external carotid arteries and drained out well via only the superior orbital vein to the angular vein.

[Gait analysis of idiopathic normal pressure hydrocephalus].

Normal pressure hydrocephalus (NPH) is a clinical syndrome associated with dementia, gait disturbance and urinary incontinence. Gait disturbance is usually the initial sign and most important symptom, but its objective evaluation has not been established. We analyzed the gait of an idiopathic NPH before and after ventricular shunting with the gait analysis system.
