A 71-year-old man with gross hematuria and urinary retention showed a 7×8 cm polycystic mass compressing the prostate on the right ventral side on pelvic magnetic resonance imaging (MRI). The prostate specific antigen (PSA) level was 6.47 ng/ml.

Purpose: To evaluate the clinical features of nosocomial epidemic keratoconjunctivitis(EKC) occurring in the ophthalmology ward of Sapporo Medical University Hospital and to devise preventive measures for it.

Materials And Methods: We studied the symptoms and clinical course of 2 patients who had EKC and 16 patients who had EKC caused by nosocomial infections in our hospital. We attempted to detect adenovirus antigen and viral DNA from conjunctival swabs and also to isolate the virus.

The potential of fly ash to dechlorinate and destroy PCDD, PCDF and PCB was tested under oxygen deficient conditions in the laboratory. Specifically, two types of fly ash were compared, originating either from a fluidized bed incinerator using Ca(OH)2 spray (FA1), or a stoker incinerator without Ca(OH)2 impact (FA2). Results from the present study indicate that on FA2 type fly ash, the degradation processes of OCDD, OCDF and D10CB occurred primarily via dechlorination/hydrogenation up to temperature settings of 340 degrees C.

The authors investigated whether theophylline metabolism is decreased in asthmatic patients and what condition may be related to its reduction. Fifty-two children with asthma were given 15 mg/kg/day aminophylline intravenously at a constant rate. Blood and spot urine samples were collected at 24 hours, 48 hours, and 72 hours after beginning infusion.

Objective: We undertook to evaluate the therapeutic effects of radiotherapy in patients with bone metastases from hepatocellular carcinoma (HCC), identify prognostic factors, and find an optimum radiation schedule.

Methods: We retrospectively analyzed the clinical records of 57 patients (99 sites) with painful bone metastases from HCC from December 1978 to March 1997. Their ages ranged from 51 to 82 yr (mean, 62 yr), and the male:female ratio was 49:8.

Hepatic actinomycosis is rare. We report an 86-year-old Japanese man with a 3-day history of high fever and anorexia who had an actinomycotic liver abscess complicated by disseminated intravascular coagulation (DIC). A definitive diagnosis was made when an Actinomyces species was cultured from aspirated pus.

Objective: To study how neuronal cells are affected by development of chronic cerebral vasospasm after subarachnoid hemorrhage (SAH), the changes in neuronal metabolites during development of vasospasm were evaluated by in vivo localized proton magnetic resonance spectroscopy (MRS) in primates.

Methods: SAH was produced by introduction of a blood clot around the right middle cerebral artery and the right side of the circle of Willis. MRS experiments were performed before SAH and on Days 7 and 14 after SAH.

The protein C anticoagulant pathway is an important downregulating mechanism of the blood coagulation cascade. We report a 47-yr-old male with Budd-Chiari syndrome and occlusion of the inferior vena cava. His plasma protein C antigen level was decreased to 42%, and its activity was 34%.

The pharmacokinetics of N4-behenoyl-1-beta-D-arabinofuranosylcytosine (BHAC), a lipophilic antitumor analog of 1-beta-D-arabinofuranosylcytosine (ara-C), was investigated, by assay of plasma and leukemic cells of ten acute leukemic patients receiving 60-minute intravenous (IV) infusion of 700 mg/m2 BHAC, for BHAC and 1-beta-D-arabinofuranosylcytosine 5'-triphosphate (ara-CTP) by high-performance liquid chromatography, ara-C by radioimmunoassay, and 1-beta-D-arabinofuranosyluracil (ara-U) by gas chromatography-mass fragmentography. The plasma concentration of BHAC reached a maximum (173.4 +/- 75.

The immune response after HB vaccination (20 micrograms, 3 times) was investigated in 15 alcoholics and the immunological background was also studied before the vaccination in some of these cases. Anti-HBs was detected in only 8 (53.3%) out of 15 vaccinated alcoholics and the anti-HBs titers of these 8 responders were less than 16 cut off index at the last observation.
