Autotransfusion supported by erythropoietin therapy in transurethral resection of the prostate.

We investigated the collection and transfusion of autologous blood after treatment with EPO in 68 BPH patients (including 10 controls) who were scheduled to undergo TUR-P. All patients received oral and/or intravenous iron supplements. Assessments were made based on the preoperative increase in blood hemoglobin levels including autologous blood predonation (deltaHb). The deltaHb in patients undergoing collection of 600 ml of blood were as follows: control group: -0.36 +/- 0.57 g/dl; EPO group, 9 x 3000 units intravenously: 1.15 +/- 0.83 g/dl; EPO group, 6 x 6000 units intravenously: 0.79 +/- 0.80 g/dl; EPO group, 3 x 12,000 units subcutaneously: 1.47 +/- 0.62 g/dl. In patients undergoing collection of 800 ml of blood, the results were as follows: EPO group, 3 x 12,000 units subcutaneously: 1.80 +/- 0.69 g/dl; EPO group, 3 x 24,000 units subcutaneously: 2.03 +/- 0.77 g/dl. All EPO-treated patients successfully underwent surgery using their own blood, and none of them required homologous transfusion. The increase of Hb was greater in the patients treated with EPO than in controls, allowing safe preoperative blood collection even in elderly patients. In patients with relatively severe BPH, homologous transfusion could be avoided and surgery was performed safely.

[A case of xanthogranuloma of the urinary bladder].

A case of xanthogranuloma of the urinary bladder is reported. A 68-year-old man was referred to our hospital for the evaluation of microscopic hematuria. At that time, he did not have an abdominal tumor and ultrasonography showed no abnormality of the kidneys and the bladder wall. Two months later, he was admitted with the chief complaints of perineal discomfort and non tender fist size mass was palpable in the lower abdomen. Ultrasonography, computed tomographic scan and magnetic resonance imaging MRI demonstrated a supravesical mass which was strongly suspected as urachal tumor. Total cystectomy with urachal resection was performed. The histological diagnosis was xanthogranuloma. The patient has been in good health without recurrence, 4 years after surgery. We discuss xanthogranuloma of the urinary bladder in the literature.

Measurement of voltage dependence of capacitance of planar bilayer lipid membrane with a patch clamp amplifier.

The voltage dependence of capacitance was measured by using the setup which was almost the same as that for the study of ion channels. The coefficient which represents the voltage dependence of capacitance itself also changes as a function of the duration of voltage application if hexadecane is contained in bilayer lipid membrane (BLM). The method of Alvarez, O., and R. Latorre (1978. Biophys. J. 21:1-17) was extended to treat BLM with hexadecane.

Malignant histiocytosis in the oropharynx.

Malignant histiocytosis is characterized by systemic, progressive, and invasive proliferation of malignant histiocytes. The disorder is typically accompanied by fever, general fatigue, lymphadenopathy, and hepatosplenomegaly. A case of a 21-year-old woman with primary malignant histiocytosis of the oropharynx is reported. Histologic diagnosis from the biopsy specimen was confused by infiltration of normal-appearing histiocytes and inflammatory cells. The titers of Epstein-Barr virus and the Paul-Bunnell test were elevated without atypical lymphocytes. The patient died 3.5 months after the onset of symptoms. Autopsy revealed systemic neoplastic proliferation of malignant histiocytes. A review of literature on this subject revealed no cases of malignant histiocytosis primarily involving the oropharynx.

Fluorescence and energy transfer of polypeptides containing naphthyl groups in their side chains.

Energy transfer in the singlet state was studied in solution at 25 degrees C for poly(beta-1-naphthylmethyl L-aspartate) and copolymers of beta-1-naphthylmethyl L-aspartate and gamma-benzyl L-glutamate. Transfer efficiencies, migration coefficients, migration lengths, and interaction radii were determined from the quenching studies using biacetyl as a quencher. The migration coefficient increases with increasing naphthyl groups in the copolymers. This means that singlet energy migrates among more naphthyl groups with increasing naphthyl groups in the polymer chain. Interaction radius for the fluorescence quenching by biacetyl was estimated to be in the range of 5.8 to 8.9 A irrespective of whether energy donor is monomer or excimer. Moreover, it was shown that energy migration via excimer does not take place and energy of the excimer is localized.
