We have treated undifferentiated mouse embryonic stem (ES) cells with all-trans retinoic acid (RA) to induce differentiation in vitro into neuron-like cells with good cell viability for use as a graft. Furthermore, we asked whether the RA-induced neuron-like cells restored neurological dysfunction. To this end, the cells were transplanted into right(More)
We induced neural cells by treating cynomolgus monkey embryonic stem (ES) cells with retinoic acid. The treated cells mainly expressed betaIIItubulin. They further differentiated into neurons expressing neurofilament middle chain (NFM) in elongated axons. Half of the cells differentiated into Islet1+ motoneurons in vitro. The monkey ES-derived neural cells(More)
The efficacy of intravenous administration of 400 mg carboplatin/m(2) body surface area over 60 minutes combined with hyperbaric oxygenation (HBO) therapy (0.2 MPa for 60 min) was investigated in 6 Japanese patients (aged 36-67 years) with malignant or brainstem gliomas. Plasma ultra-filtrate samples were analyzed by high-performance liquid chromatography(More)
Mouse embryonic stem (ES) cells were transfected with a MASH1 expression vector and G418-resistant cells were selected. The MASH1-transfected cells became neuron-like appearance and expressed betaIIItubulin and panNCAM. Glial fibrillary acidic protein (GFAP) and galactocerebroside (GalC)-expressing cells were rarely detected. Half of the neural cells(More)
We developed neural tube-like structures accompanying neural crest-like cells by treating embryonic stem (ES) cells with retinoic acid. The structures contained pseudostratified Nestin+Vimentin+ neuroepithelial cells surrounded by Masson staining+ basement membrane. betaIIItubulin+Synaptophysin+ mature neurons and glial fibrillary acidic protein (GFAP)+(More)
Both leucovorin (LV) and cisplatin (cis-dichlorodiammine platinum II, CDDP) act as modulators of 5-fluorouracil (5-FUra) by increasing the intracellular concentration of reduced folate. We measured intracellular folate levels following the administration of LV or cisplatin in tumor-bearing rats to determine the optimal schedules for their use as 5-FUra(More)

Traumatic lesions of the brain stem are of two types: primary, which are considered to be caused at the moment of impact, and secondary, associated with supratentorial mass lesion. Of the 239 patients with a serious head injury who showed a severe disturbance of consciousness upon admisision and who had CT scan carried out immediately, 21 cases were(More)
We report a case of post-neurosurgical meningitis, subdural empyema, and cerebral abscess caused by multidrug-resistant Acinetobacter baumannii (MRAB) poorly susceptible to colistin. A 49-year-old man was transferred to our hospital after surgical treatment for putaminal hemorrhage in a foreign country hospital. Several examinations revealed surgical site(More)
We report two cases of lymphocytic infundibuloneurohypophysitis (LIH). A 32-year-old male and a 13-year-old male were admitted to our hospital because of a sudden occurrence of the diabetes insipidus (DI). MRI of both patients showed the disappearance of hyperintensity of the posterior pituitary in T1WI, pituitary stalk swelling and enlargement of the(More)
A 22-year-old woman developed an unruptured fusiform aneurysm of the internal carotid artery 7 months after being diagnosed with Wagener's granulomatosis. Intracranial aneurysmal formation is an extremely rare complication of Wegener's granulomatosis. This rare case of intracranial aneurysm was treated by endovascular balloon occlusion.
