Postural control skills and quadrupedal locomotor pattern in infant rolling mice, a neurological mutant, were observed in the following situations: hindlimb support when suspended, rope descent, narrow path traverse, quadrupedal locomotion on an inclined corridor, and swimming behavior when entirely submerged. Until the second week of age, rolling mice(More)
We report a case of acute enlargement of the ventricles within 7 hours after head injury that was documented by repeated computerized tomography. It is suggested that the pathophysiological mechanism for this rapid enlargement of ventricles may be due to the raised intracranial pressure (ICP) that results from obstruction of cerebrospinal fluid pathways by(More)
Esophageal cancer patients are often associated with multiple primary cancers (MPC). The aim of this study is to evaluate the effect of MPC on prognosis in esophageal cancer patients treated by radiotherapy. Between 2001 and 2008, esophageal cancer patients treated by definitive radiotherapy at Gunma Cancer Center were retrospectively reviewed. Exclusion(More)
Thyrotropin-releasing hormone (TRH) was injected intraperitoneally into male Fischer344 rats in doses ranging between 1 mg/kg and 20 mg/kg to assess the effects on the acquisition and extinction of shuttlebox-avoidance behavior. Administration of 20 mg/kg TRH resulted in a rapid acquisition of avoidance behavior in early training trials. This enhancement(More)
Single and combined treatment of interstitial microwave hyperthermia (HT) and radiation therapy (RT) were delivered to rat glioma models. The animal model tumors were induced by intracerebral inoculation of a small piece of G-XII glioma tissue to 6-8 week-old rats. Heating to about 44 degrees C at the surface of the inserting antenna using a 2450 MHz(More)
Male Fischer344 rats were exposed to x-irradiation at a dose of 200 rad on Day 17 of gestation. Irradiated and control rats were tested at 10-13 weeks of age with the paradigm of go/no-go (active-passive) discriminated avoidance conditioning for three consecutive daily sessions. During the first conditioning session, they learned only active avoidance(More)
Rat glioma model was used to evaluate the effect of hyperthermia with and without radiation therapy. The animal model was induced by left frontal burr hole opening and inoculation of a small piece of G-XII glioma tissue to 6- to 8-week-old rats. The therapeutical experiments were given 10-14 days after inoculation of the tumor. Interstitial heating at 44(More)
Groups of MPI male albino rats were exposed to x-irradiation of 200 rad on Day 17 of gestation. Irradiated and control rats were trained in a shuttle box with either immediate or .5-sec delayed termination of both the electric shock (US) and the conditioned stimulus (CS) on escape trials. An avoidance response always produced prompt CS termination.(More)
