目的:探讨拉米夫定辅助治疗对肺结核合并乙型肝炎患者的肝功能的影响和安全性。方法:选择2009年1月至2013年6月在我科门诊就诊或住院的肺结核合并乙型肝炎患者84例,随机均分为对照组与观察组,对照组给予常规治疗措施,观察组在上述基础上加用拉米夫定治疗,检测和比较两组患者治疗前和治疗后6个月相关临床指标及不良反应的发生情况。结果:治疗前,两组患者的总胆红素(TBIL)、丙氨酸转氨酶(ALT)、谷草转氨酶(AST)和HBV-DNA定量结果比较,差异均无统计学意义(均P0.05);治疗6个月后,观察组以上指标均显著低于对照组,差异均具有统计学意义(均P0.05)。两组患者治疗过程中均出现恶心、腹胀、乏力、肝区不适与肝功能损害,观察组以上不良反应的发生率均显著低于对照组,差异具有统计学意义(均P0.05)。结论:在肺结核合并乙型肝炎患者的抗结核药物治疗过程中加用拉米夫定不仅可显著抑制患者肝功能的损害,且安全性性更高。 相似文献

Mesophilic aerobic Gram negative cellulose degrading bacteria from aquatic habitats and soils 总被引:1,自引:1,他引:0
New procedures have been developed for the isolation and purification of aerobic and facultatively anaerobic bacteria able to utilize cellulose as sole source of carbon and energy. Wood pulp medium was used for enrichment, and bacterial cellulose, obtained from cultures of Acetobacter aceti subsp. xylinus , was employed as carbon substrate during purification and for the rapid screening of colonies for cellulolytic activity. The methods have revealed several new groups of Gram negative cellulose-degrading bacteria, including organisms that form differentiated colonies superficially similar to myxobacterial sori. The organisms formed several phenetic clusters, three of which contained reference strains of Cellvibrio fulvus, Pseudomonas fluorescens var. cellulosa and Cytophaga hutchinsonii . No cellulose degrading cluster included non-cellulose degrading strains. Most of the cellulose degraders studied were flagellated and, of these, the majority had polar or lophotrichous flagella, although one cluster included peritrichously flagellated organisms. The cellulose degraders in this study included five organisms that grew on nitrate-free medium; these appeared in two different clusters. A few Gram positive isolates appeared to belong to the genera Streptomyces and Thermoactinomyces . 相似文献

The bulk ore carrier Apollo Sea sank near Dassen Island, South Africa, on 20 June 1994 during a period of winter storms. Approximately 10 000 African (Jackass) Penguins Spheniscus demersus were oiled, collected and transported to the SANCCOB rescue centre; 5213 were released after cleaning, 4076 with flipper bands. We believe that most of the penguins oiled during this incident reached an island or the mainland alive, and that there was no mass mortality in the wild at the time of the oil spill. Birds from all parts of the breeding range were oiled, but most were from Robben and Dassen Islands. The overwhelming majority of released birds made the transition from the rescue centre to the wild successfully; 2652 had been resighted at breeding colonies within two years of their release; the cumulative number of birds was increasing steadily and an asymptote had not been reached by August 1996. There was a wide dispersal of released penguins, with recoveries and resightings over 1800 km of coastline between Algoa Bay and Walvis Bay. 相似文献

Ixodes (Pholeoixodes) hexagonus, an efficient vector of Borrelia burgdorferi in the laboratory 总被引:2,自引:0,他引:2
LISE GERN LINA N. TOUTOUNGI CHANG MIN HU RE AESCHLIMANN 《Medical and veterinary entomology》1991,5(4):431-435
Borrelia burgdorferi Johnson et al. was first isolated from the midgut of Ixodes dammini Spielman et al. in the U.S.A. and from the midgut of I.ricinus (L.) in Europe. I.ricinus was considered to be the only tick vector of this borrelia, in Europe, until I.hexagonus Leach, the hedgehog tick, was found to harbour spirochaetes. This paper reports an evaluation of the vector competence of I.hexagonus for the spirochaete B.burgdorferi. Transovarial and trans-stadial survival were demonstrated and the spirochaete was transmitted to laboratory mice via the bites of trans-stadially infected I.hexagonus females. 相似文献

The use of antimicrobial peptides (AMPs) synthesized
by bacteria (bacteriocins) is an alternative for combating multidrug
resistant bacterial strains and their production by recombinant route
is a viable option for their mass production. The bacteriocin E-760
isolated from the genus Enterococcus sp. has been shown to possess
inhibitory activity against Gram-negative and Gram-positive
bacteria. In this study, the expression of a chimeric protein coding
for E-760 in the nucleus of C. reinhardtii was evaluated, as well as,
its antibacterial activity. The synthetic gene E-760S was inserted
into the genome of C. reinhardtii using Agrobacterium tumefaciens.
A transgenic line was identified in TAP medium with hygromycin
and also by PCR. The increment in the culture medium temperature
of the transgenic strain at 35 °C for 10 minutes, increased the
production level of the recombinant protein from 0.14 (Noninduced
culture, NIC) to 0.36% (Induced culture, IC) of total soluble
proteins (TSP); this was quantified by an ELISA assay. Recombinant
E-760 possesses activity against Staphylococcus aureus in 0.34 U
log, Streptococcus agalactiae in 0.48 U log, Enterococcus faecium in
0.36 U log, Pseudomonas aeruginosa in 2 U log and for Klebsiella
pneumoniae, the activity was 0.07 U log. These results demonstrate
that the nucleus transformation of C. reinhardtii can function as
a stable expression platform for the production of the synthetic
gene E-760 and it can potentially be used as an antibacterial agent. 相似文献
