A 68-year-old woman had pulmonary aspergilloma in the right upper lobe with old cavitary pulmonary tuberculosis. Despite intravenous fluconazole there was no change in the size of the fungus ball. Endobronchial instillation of fluconazole also failed. Subsequently percutaneous instillation of fluconazole was attempted with localized drainage. The fungus ball decreased in size after 8 weeks. Although slight hemoptysis and subcutaneous emphysema occurred in this case, these condition required no treatment. This method of treatment appears to be useful for inoperable cases of pulmonary aspergilloma. 相似文献

A 59-year-old male was admitted because of severe chest pain and diagnosed as inferior myocardial infarction by ECG and enzymologically, who had a Levine grade II continuous murmur in the left second intercostal space at the left sternal border. Cardiac catheterization revealed a 8% left to right shunt at pulmonary artery. Selective coronary cineangiography revealed left anterior descending-to-main pulmonary artery and left circumflex-to-main pulmonary artery fistulas, and severe atherosclerotic stenosis at right coronary and left anterior descending arteries. Operation was performed simultaneously, closure of two drainage orifices of the fistulous vessels through pulmonary arteriotomy and aortocoronary bypass grafting to left anterior descending under cardiopulmonary bypass. The postoperative course was uneventful, and the murmur was disappeared. 相似文献

Deletion of Mycobacterium tuberculosis sigma factor E results in delayed time to death with bacterial persistence in the lungs of aerosol-infected mice 下载免费PDF全文
The stress-induced extracytoplasmic sigma factor E (SigE) of Mycobacterium tuberculosis shows increased expression after heat shock, sodium dodecyl sulfate treatment, and oxidative stress, as well as after phagocytosis in macrophages. We report that deletion of sigE results in delayed lethality in mice without a significant reduction of bacterial numbers in lungs. 相似文献

Antigenic Characterization of Hantaan and Seoul Virus Nucleocapsid Proteins Expressed by Recombinant Baculovirus: Application of a Truncated Protein, Lacking an Antigenic Region Common to the Two Viruses, as a Serotyping Antigen 总被引:11,自引:1,他引:11 下载免费PDF全文

Hantaan virus (HTN) and Seoul virus (SEO) are members of the genus Hantavirus in the family Bunyaviridae and are causative agents of hemorrhagic fever with renal syndrome. The complete and truncated nucleocapsid proteins (NP) of HTN and SEO were expressed by a recombinant baculovirus system. Antigenic characterization of the NP using monoclonal antibodies (MAbs) indicated that the binding sites for the serotype-specific MAbs were located between amino acids (aa) 155 and 429. A Western blot assay indicated that the serotype-specific epitopes were conformation dependent. An indirect immunofluorescence antibody (IFA) assay with the truncated NP (aa 155 to 429) was able to distinguish convalescent-phase sera from HTN and SEO patients. However, the antibody titers with the truncated NP were lower than those with the whole NP. The truncated NP of SEO (aa 155 to 429) could be used as an enzyme-linked immunosorbent assay (ELISA) antigen, but the truncated NP from HTN lost its reactivity when used for ELISA. The IFA assay using baculovirus-expressed truncated NP as an antigen is a rapid, simple, and safe test for distinguishing between HTN and SEO infections by serotype. 相似文献

Genetic diversities of hantaviruses among rodents in Hokkaido, Japan and Far East Russia 总被引:4,自引:0,他引:4

Seroepizootiologic surveys among wild rodents were carried out in Japan and Far East Russia in 1995 and 1996. Seropositive animals were only identified in Clethrionomys rufocanus (23/134) in Hokkaido, Japan. On the other hand, seropositives were identified in C. rufocanus (1/8), Apodemus agrarius (2/66), Apodemus spp. (2/26) and Microtus fortis (3/22) in Vladivostok, Far East Russia. Total RNA was isolated from lungs of seropositive animals and the S genome segments were amplified by PCR, cloned and sequenced. The S and M genomes of hantavirus, derived from Japanese C. rufocanus (Tobetsu genotype), were most closely related with Puumala viruses (76-79% nucleotide and 95% amino acid identities for S genome, 70-78% nucleotide and 87-92% amino acid identities for M genome). The recombinant nucleocapsid protein of Tobetsu genotype was antigenically quite similar with that of Sotkamo. These suggest that the virus endemic in Japanese C. rufocanus belongs to Puumala virus. Phylogenetic analysis indicates that the genotype forms a distinct lineage within Puumala viruses. Partial S segment (1-1251 nt), derived from seropositive M. fortis in Vladivostok, was sequenced and analyzed. The S genome segment, which was designated Vladivostok genotype, was most closely related with Khabarovsk virus (79% nucleotide and 90% amino acid identities) which was isolated from M. fortis. 相似文献

Modulation of neuronal histamine in control of food intake 总被引:4,自引:0,他引:4

Neuronal histamine affects physiological functions of the hypothalamus. To investigate involvement of histamine receptors in feeding, histamine antagonists were infused into the rat third cerebroventricle. All H1- but no H2-antagonists tested, induced transient feeding during the early light when concentration of hypothalamic histamine was highest. No periprandial drinking was observed. Ambulation concomitantly increased during feeding. The effect on feeding was attenuated when brain histamine was normally low during the early dark or was decreased by alpha-fluoromethylhistidine (alpha-FMH). Bilateral microinjection indicated that the ventromedial hypothalamus, but not the lateral hypothalamus or the paraventricular nucleus, was a main locus for the induction of feeding by an H1-antagonist. The effect was completely abolished when brain histamine was decreased by pretreatment with alpha-FMH. Hypothalamic neuronal histamine suppresses food intake, at least in part, through H1-receptors in the VMH, and diurnal fluctuations of food intake may mirror neuronal histamine level. 相似文献

Intraplacental choriocarcinoma is very rare, and is usually found only after maternal and fetal metastatic disease is identified. The purpose of this case report is to review the incidence and findings of intraplacental choriocarcinoma. A term placenta was investigated because the newborn was born with severe anemia (Hb 3.0 g/dL). A 2 cm nodule was noted on the surface of the amniotic membrane and grossly resembled an infarction. The tumor was examined microscopically with immunohistochemical staining for the alpha- and beta-human chorionic gonadotropin (alpha-hCG, beta-hCG) subunits, human placental lactogen (hPL) and Ki-67. Microscopically, the tumor consisted of necrotic areas with proliferation of atypical trophoblastic cells and destruction of the villi and capillaries. The cells were positive for the alpha-hCG, beta-hCG subunits, hPL and Ki-67, consistent with intraplacental choriocarcinoma. The mother and newborn were investigated for the presence of metastatic disease. Computed tomography scans and magnetic resonance imaging of the mother and infant were negative for metastatic disease. Choriocarcinoma, limited only to the placenta with no evidence of metastatic disease is very rare. Primary intraplacental choriocarcinoma may frequently be overlooked or missed, and choriocarcinoma may possibly arise in the placenta more often than in retained or persistent trophoblast following pregnancy. 相似文献

Summary. Bovine lactoferrin (LF) and ribavirin (Rbv) were tested as antiviral agents against Seoul type hantavirus (SR-11 strain)
in vitro. Hantaviral foci number in Vero E6 cells infected with SR-11 was reduced with LF treatment by 5 days post infection
to obtain a 50% effective dose (ED50) of 2500 μg/ml, while pretreatment with LF was highly efficacious having an ED50 of 39 μg/ml. Conversely, 1 h pretreatment with Rbv revealed no inhibition of viral focus formation but could significantly
reduce the number of viral foci (ED50: 10 μg/ml) when used from the time of viral infection. One hour pre-treatment of the cell monolayer with LF and subsequent
addition of Rbv revealed a synergistic anti-hantaviral effect against SR-11, <20 FFU/ml as compared to 105 foci/ml in the control. One hour treatment of SR-11 with LF prior to cell inoculation gave an ED50 of 312.5 μg/ml. Whereas, washing the LF-pretreated cell monolayer with PBS demonstrated minimal focus reduction, suggesting
LF lightly adheres to cells. These results indicate that LF has anti-hantaviral activity in vitro and inhibition of virus
adsorption to cells which play an important role in revealing the anti-hantaviral activity of LF. This paper reports for the
first time the anti-hantaviral effect of LF.
