Abstract | The precise distribution of thyrotropin releasing hormone (TRH) in 23 discrete brain nuclei and areas of Wistar strain male rats was determined by specific radioimmunoassay. TRH was detected in most of these areas. The highest concentration was found in the median eminence (27.52 +/- 2.84 ng/mg protein). The arcuate nucleus (4.92 +/- 0.58 ng/mg protein), dorsomedial nucleus (4.77 +/- 0.59 ng/mg protein) and medial preoptic area (3.94 +/- 0.15 ng/mg protein) also contained a considerable concentration of TRH. However, no TRH was detected in cerebral cortex, cerebellar hemisphere, anterior pituitary or pineal body. The data indicated that TRH was widely distributed throughout the hypothalamus; in particular, high concentrations occure in relatively restricted areas: in the median eminence, arcuate nucleus, dorsomedial nucleus and medial preoptic area. These areas coincide well with the so-called "thyrotropic" area of the hypothalamus. |

Abstract | <p>The levels of HDL-cholesterol and gamma-glutamyltransferase in the sera of 17 patients with alcoholic liver injury were followed after abstinence and compared with those of 11 patients with acute non-alcoholic hepatitis. The activity of gamma-glutamyltransferase decreased in all cases irrespective of the type of liver injuries. The level of HDL-cholesterol also decreased in 11 of 17 cases with alcoholic liver injury. The other alcoholics, in whom HDL-cholesterol level increased or showed no definite change after withdrawal of alcohol, had severe and advanced liver injuries. In non-alcoholic hepatitis, the HDL-cholesterol level increased as normal liver functions were restored except for one case with cholestatic features. It was concluded that alcohol intake can increase HDL-cholesterol level even in the presence of a concomitantly induced hepatic lesion.</p> |

Abstract | The effectiveness of tranexamic acid treatment for sudden deafness was studied in detail. The results of treatment with tranexamic acid administration in 19 cases (25 ears) of sudden deafness and two historical control groups using various treatments were compared by the chi square contingency test. The data suggested that tranexamic acid treatment may be superior to traditional treatments especially if treatment is begun early. Among ears treated with tranexamic acid, 11 ears (44%) were healed or recovered remarkably, 8 ears (32%) recovered slightly and 6 ears (24%) were unchanged or worsened. Fibrinolysis in the inner ear may be the pathophysiology of sudden deafness. Treatment with tranexamic acid starting within 4 days after onset of symptoms was most effective in patients whose initial audiogram was flat or concave, initial average hearing loss at 5 frequencies (250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz) was between 23 dB and 76 dB (mean; 45.1 dB) and was not accompanied by dizziness. |

Abstract | <P>A 73-year-old man with a left testicular tumor is presented. Orchiectomy was performed and the tumor was diagnosed as a plasmacytoma. There has been no bone lesion or immunoglobulin abnormality during a follow-up period more than one year. For several reasons, the tumor was regarded as a primary plasmacytoma of the testicle. The literature concerning testicular plasmacytoma is reviewed briefly. |

Abstract | The three-dimensional architecture of the collagen framework of human lumbar intervertebral discs was studied with scanning electron microscopy and polarized light microscopy concentrating on the fibrillar interconnection between the intervertebral disc and the vertebral bodies. The fibrillar framework of the annulus fibrosus and the cartilage end-plates encircled the nucleus pulposus as a closed-pack system in the adult. This closed-pack system developed in the seventh embryonic month and was completed by the tenth month. In general, fibrils composing the framework in the fetus were thinner than in the adult. There was no fibrillar interconnection between the cartilage end-plate and subchondral bone. In the inner one-third of the annulus, obliquely oriented fibrillar lamellae interconnected with the cartilage end-plate. In the outer two-thirds, the fibrillar bundles of the lamellae were firmly anchored into the vertebral bodies. This fibrillar anchoring system was already present in the full-term fetus although the vertebral rim was not ossified. |

Abstract | Twelve patients with refractory acute leukemia (7 patients with acute myelocytic leukemia and 5 patients with acute lymphocytic leukemia) were treated with a new anthracycline antibiotic, aclacinomycin-A (ACM). ACM was administrated by intravenous drip infusion at a dose of 20 mg/day for 7 or 14 days and this was repeated after at least 7 days. Four of 12 patients (33.3%) achieved a complete remission; 3 of 7 acute myelocytic leukemia (42.8%) and 1 of 5 acute lymphocytic leukemia (20.0%). The days required for achieving the complete remission ranged from 23 to 78 days (median: 61) and the total doses of ACM used from 180 to 500 mg (median: 310), and the durations of complete remission from 11 to 28+ weeks (median: 21+). The untoward effects on digestive organs, such as nausea, vomiting and anorexia, and hematological toxicities were frequently seen; however, they were controlled by supportive treatment. Alopecia was not observed. Arrythmia was recognized in one patient at the initiation of ACM infusion with complete remission without withdrawal of ACM. These results suggest that ACM is a potentially effective anthracycline antibiotic in the clinical management of acute leukemia. |

Abstract | A rare case of bilateral fat necrosis of the breast is reported. The patient was a 50-year-old unmarried woman having no history of trauma, disease or surgery of the breast. In the bilateral breasts, ill-defined, firm masses with skin retraction were noted. Bilateral breast cancer was diagnosed clinically. However, both lesions showed histologically chronic granulomatous inflammation with foci of fatty necrosis, infiltration of lymphocytes, plasma cells, lipid containing foamy cells, foreign body giant cells engurfing choresterol-crystals, and calcification. "Paraffinoma" was thus suspected, but there was no history of cosmetic mammoplasty and histochemical studies failed to demonstrate saturated lipid indicating paraffin or other mineral oils |
