5-Aminolevulinic acid (ALA) has been successfully used to confirm the target tumor tissues obtained during stereotactic biopsy. The authors report their experience with 2 patients who underwent stereotactic biopsies of thalamic malignant lymphoma and pontine glioma utilizing 5-ALA. Intraoperatively, the tumor specimens fluoresced, allowing for confirmation(More)
The protective role of interleukin (IL)-12 against influenza infection was assessed by analyzing the efficacies of orally administered clarithromycin (CAM) as an immunomodulator and intranasal administration of recombinant IL-12 in intranasally influenza virus-infected mice. In infected mice, CAM at 20 mg/mouse/day significantly elevated the levels of IL-12(More)
Herpetic infection causes paresthesia, including hypoalgesia, in humans and hypoalgesia in rats. This study was conducted to examine the effect of caffeine, which inhibits replication of herpes simplex virus type-1 (HSV) and affects several neuronal functions, on HSV-induced paresthesia in rats. HSV-induced hypoalgesia was suppressed by repeated treatment(More)
In a study of duration of brain death, granular layer autolysis (GLA) of the cerebellar cortex was analyzed in 45 patients who died of acute cerebrovascular diseases (CVDs). Twelve patients who died of causes other than intracranial disease served as controls. Tonsillar herniation occurred in all who died of acute CVDs. More advanced GLA was seen in the(More)
A case of primary brainstem death in a man with surgically treated cerebellar haemorrhage is reported. Necropsy revealed extensive necrosis confined to the brainstem and cerebellum. The absence of diabetes insipidus and the persistence of electroencephalographic activity were the characteristic clinical features of the case. This differentiates the(More)
To clarify the feasibility of the herpes simplex virus (HSV) vector in expressing the foreign gene in the motor neuron, we inoculated a live attenuated HSV expressing beta-galactosidase (beta-gal) activity under a latency-associated transcript promoter in the right gastrocnemius muscle of rats. Expression of beta-gal activity was observed 5 days after(More)
7-Amino-4-methylcoumarin (AMC) was previously shown to suppress pro-inflammatory cytokine production and prevent death in an endotoxic shock model in mice. In the present study, we investigated the effectiveness of AMC as a potential cytokine modulator in alleviating autoimmune diseases. We examined the efficacy and cytokine-modulatory activity of AMC in(More)
