We report a rare case of granulomatous balanoposthitis after intravesical Bacillus-Calmette-Guerin (BCG) instillation therapy in a 58-year-old man, which followed transurethral resection (TUR) for recurrent bladder cancer, when his anterior urethra was slightly narrow and his foreskin was with phimosis. Intravesical BCG instillation therapy was started for prophylaxis of recurrent bladder cancer after TUR. Multiple painless firm papules on glans penis, edema in the foreskin and low-grade fever appeared after the seventh instillation, for which the single antituberculous agent isoniazid (300 mg/day) was administered. Biopsy of the papules on glans penis and foreskin revealed granulomatous balanoposthitis. Low-grade fever normalized and the papules disappeared within 1 week. The patient continued chemotherapy with isoniazid for the next 12 months. There was no recurrence of bladder cancer or balanoposthitis for 15 months and to date. 相似文献

A phase II study of mitoxantrone was performed in 24 patientswith non-small cell lung cancer (NSCLC). Mitoxantrone was administeredby intravenous drip infusion of 12 mg/m2 every three weeks.There were no responders among the 21 evaluable patients includingfive patients without prior therapy. The major hematologicaltoxic effect was leukocytopenia. Thrombocytopenia and decreasein hemoglobin were slight. A change in the electrocardiogramwas observed in one patient and one patient experienced cardiogenicshock. Mitoxantrone is not acceptable for the treatment of NSCLC becauseof its low antitumor activity, and careful observation is neededfor administration of this agent to patients with pre-existingrisk factors, such as prior anthracycline exposure, mediastinalradiation or underlying cardiovascular disease. 相似文献

The roles of IgE and mast cells on expulsion of adult Hymenolepis nana from the intestine were examined in mice. IgE-dependency was determined by comparing congenitally IgE-deficient SJA/9 and IgE-producing SJL/J mice infected with 50 H. nana eggs. Anti-H. nana IgE antibody was detected at three weeks post infection (p.i.) in SJL but not in SJA mice. The number of adult worms in the intestines of SJA and of SJL mice were similar at two weeks, but significantly more were found in SJA mice at three weeks p.i. Treatment of mice with anti-ɛ antibody also resulted in an increased worm burden at three weeks, suggesting participation of IgE in expulsion of H. nana. Intestinal mastocytosis was induced by infection regardless of the IgE status of the mice. Mast cell-dependency was tested in mast cell-deficient W/Wu and in normal littermate +/+ mice infected with 100 H. nana eggs. Anti-H. nana antibody was detected in both groups of mice at three weeks p.i. Worm expulsion seemed to be mast cell dependent because expulsion was less complete in W/Wu mice at three weeks p.i. Peripheral blood eosinophilia was comparable at three weeks p.i. in both IgE and mast cell sufficient and deficient mice. These results suggest that IgE and mast cells participate in the expulsion of H. nana adults from intestine in mice. 相似文献

The time-dependent effects of Klebsiella pneumoniae endotoxin on hepatic cytochrome P450-dependent drug-metabolizing capacity (cytochrome P450 and b5 content, activity of aminopyrine N-demethylase, p-nitroanisole O-demethylase, aniline hydroxylase and benzphetamine N-demethylase) and on the pharmacokinetics of antipyrine have been determined in rats. Measurement of enzyme activity and antipyrine (after intravenous injection of 20 mgkg?1) were performed 2, 24 and 96 h after a single intraperitoneal injection of endotoxin (1 mgkg?1) and after repeated doses (once daily for 4 days). The contribution of tumour necrosis factor α (TNFα) to the endotoxin-induced changes was also examined in rats pretreated with granulocyte colony-stimulating factor (G-CSF). The systemic clearance of antipyrine and the activity of hepatic cytochrome P450-dependent drug-metabolizing enzymes were dramatically reduced 24 h after a single injection of endotoxin, but had returned to control levels by 96 h. The magnitudes of these decreases in these measurements after repeated doses of endotoxin were similar to those seen 24 h after the single dose. The systemic clearance of antipyrine correlated significantly with cytochrome P450 content and aminopyrine N-demethylase activity. In histopathological experiments, moderate hypertrophy of Kupffer cells was observed, with no evidence of severe liver-tissue damage. G-CSF pretreatment suppressed the increased plasma concentrations of TNFα produced 2 h after single endotoxin injection, but did not eliminate the endotoxin-induced decrease in the systemic clearance of antipyrine, suggesting that TNFα is not the sole component responsible for the reduction of cytochrome P450-mediated drug-metabolizing enzyme activity. These results provide evidence that a single intraperitoneal injection of 1·0 mgkg?1 K. pneumoniae endotoxin in rats reduces hepatic P450 and b5 levels, and reduces the activity of various cytochrome P450-mediated drug-metabolizing enzymes without causing severe liver-tissue damage. This suggests that the effect of endotoxin on hepatic cytochrome P450-mediated drug-metabolizing isozymes is non-selective. 相似文献

The effects on humans of lead acetate exposure may involve thecranial nerves, since vertigo and sensory neuronal deafnesshave been reported in lead workers; however, there exist onlya few reports concerning the dose effects of lead acetate bothon the cochlea and the eighth cranial nerve. The effects oflead acetate on the cochlea and the eighth nerve were investigatedsystematically using cochlear microphonics (CM), wholenerveaction potential (AP), and endocochlear potential (EP) in guineapigs (male albino Hartley). Guinea pigs were injected with 2ml of a 1% solution of lead acetate (20 mg) once a week for15 weeks. The threshold of whole-nerve AP (N1) was elevatedby injection of lead acetate, even 40 mg, and whole-nerve AP(N1) output voltage decreased after injection of 100mg of leadacetate. On the other hand, no change was observed in CM afterlead acetate injection (100 mg) or in EP after lead acetateexposure (40 mg). The blood concentrations of lead acetate wereas follows (mean): control, 4.5 µg/dl; Expt 1, 80 µg/dl;Expt 2, 126 µg/dl; Expt 3, 142 µg/dl;. We concludethat dysfunction of the eighth nerve is induced by high-doselead exposure, but that lead exposure does not induce electrophysiologicaldysfunction of the organ of Corti and the stria vascularis. 相似文献

A sensitive sandwich enzyme-linked immunosorbent assay (ELISA) has been established to estimate serum thrombopoietin (TPO) concentrations in healthy volunteers and patients with haemopoietic disorders. The ELISA uses a mouse monoclonal antibody (Ab) as the capture Ab and a biotinylated rabbit polyclonal Ab as the detector. The ELISA was reproducible, highly sensitive and specific for human TPO. The coefficients of intra- and inter-assay variation were from 3.0% to 4.9% and from 5.9% to 6.1%, respectively. The quantitative limit of the ELISA was 0.09 fmol/ml in serum. The quantitative limit was lower than the normal level. The dose–response curves of serum samples from healthy volunteers and patients with haemopoietic disorders were parallel to the standard curves. The ELISA did not cross-react with a variety of blood components and cytokines to produce false-positive results.
The serum TPO concentrations from 29 normal males and 21 females were 0.79 ± 0.35 and 0.70 ± 0.26 fmol/ml, respectively. Serum TPO levels in patients with aplastic anaemia (AA), acute lymphocytic leukaemia (ALL) and essential thrombocythaemia (ET) were measured using the ELISA. The serum TPO levels in the patients with ET ( n = 6, 2.80 ± 1.55 fmol/ml) were higher than the normal level. The patients with AA ( n = 7, 18.53 ± 12.37 fmol/ml) and ALL ( n = 5, 10.36 ± 5.57 fmol/ml) had significantly higher serum TPO levels than normal individuals. These results indicate that the ELISA specific to TPO should prove useful in measuring the TPO concentration in serum samples. 相似文献

Mass examinations of the stomach were carried out on 79 convicts over 40 years of age confined in the Miyagi Prison, Japan. Of the 79 subjects, 11.9% were found to need detailed examination of the stomach which disclosed gastric polyp in one case and scar from gastric ulceration in one. None was found to have carcinoma of the stomach. Complaints of symptoms were obviously more frequent with the convicts as compared with a control group. There was not, however, a significant depression in efficiency of this group examination by photofluorography, as compared with the usual gastric mass examination on general inhabitants. 相似文献

The solution conformations of novel dipeptides, methyl (2S, 3′S)-3-methyl-2-(2′-oxo-3′-isopropyl-1′-piperazinyl)-butanoate (EVV-OCH3), methyl (2S, 3′S)-3-phenyl-2-(2′-oxo-3′-benzyl-1′-piperazinyl) propionate (EFF-OCH3), and their derivatives (Boc-Gly-EW-OH, Boc-Gly-EVV-Gly-OH, and Boc-Gly-EFF-OH), were studied by ‘H NMR measurements and molecular mechanics calculations (1). The molecular structures of Boc-Gly-EVV-OH, Boc-Gly-EFF-OH, and the hydrochloride of EVV-OCH3 were determined by X-ray analyses. The conformations of the piperazinone rings and the side chains of these oligopeptides were clarified. 相似文献

Radiofrequency (RF) catheter ablation has been used for the treatment of ventricular tachycardia (VT), however, in some patients VT might result from subepicardiai macroreentry that could be successfully terminated by epicardial approach. This study examined the feasibility of thoracoscopic RF ablation of myocardium from epicardium using a custom made electrode. In five mongrel dogs, the thoracoscope was introduced through the 7th intercostal space. A 500-kHz continuous wave RF energy was connected to a custom made multiple electrode probe. Under thoracoscopic guidance, the heart was exposed and the RF probe was introduced. RF ablation was performed on the nonvascular ventricular wall of the beating heart. The left ventricular free wall and right ventricular outflow tract were satisfactorily visualized and ablated. The total dose of RF energy ranged from 50 to 500 J. and the estimated volume of ablated lesions ranged from 41.0–799 mm3 . There were significant correlations between the RF discharge output and the irradiated lesion volume (P < 0.01), and the depth of the lesions (P < 0.01). Grossly, after RF ablation the ventricular myocardium demonstrated a circular, well-demarcated area of thermal injury. Volume and depth of the lesion depended upon the total dose of delivered RF energy. Thoracoscopic RF ablation appears to be a minimally invasive and useful method for creating irradiated myocardial lesions from epicardial surface. This method could he technically feasible for the treatment of Vts for which endocardial RF ablation is ineffective. 相似文献

Effects of dual chamber A V sequential pacing on coronary flow velocity, especially systolic reversal flow, were tested in a patient with hypertrophic obstructive Cardiomyopathy. AV sequential pacing with shorter AV delays reduced the systolic reversal flow in the coronary artery, and improved the pressure gradient of the left ventricular outflow tract. 相似文献
