Histamine decreases food intake by activating histaminergic neurons in the hypothalamus. Histamine is synthesized by histidine decarboxylase (HDC) from histidine. The purpose of this three-part animal study was to clarify the mechanism underlying the suppressive effect of dietary histidine on food intake. In experiment 1, we attempted to distinguish(More)
Treatment with serotonin and acetylcholine depletors reduced the number of synapses in the rat hippocampus. Animals that received the drug treatment lost a substantial number of synapses and showed an apparent impairment in memory acquisition. Although the animals were behaviorally impaired following the treatment, spatial memory was nonetheless eventually(More)
We report an extremely rare case of squamous cell carcinoma (SCC) of the renal pelvis associated with an incompletely duplicated renal pelvis and ureter. A 71-year-old woman presented with left lower back pain and gross hematuria. Urinary cytology showed atypical squamous cells. Computed tomography, magnetic resonance imaging and retrograde pyelography(More)
The atlas of a 52-year-old male Japanese cadaver, which had been removed and macerated, presented a bilateral unknown bone bridge forming a foramen (Case 1). The bone bridge connected the ponticulus lateralis (PL) and posterior (PP) to form an oval foramen between the superior roots of both ponticuli. The atlas of a 69-year-old male Japanese cadaver was(More)
We describe an extremely rare case of congenital neuroblastoma with placental involvement. A fetus with a left abdominal mass detected during ultrasonography at 23 weeks' gestation developed hydrops fetalis by 26 weeks' gestation. The mother developed hypertension at 26 5/7 weeks' gestation. Based on a clinical diagnosis of pregnancy-induced hypertension,(More)
