The in vitro susceptibilities of 21 Aspergillus isolates were tested against three antifungal agents in RPMI 1640 and yeast nitrogen base at pH 5.0 and 7.0 by a broth microdilution format of the NCCLS method. The MICs of amphotericin B and itraconazole were higher, while those of flucytosine were lower, at pH 5.0 than at pH 7.0. The poor correlation between in vitro results and clinical outcome...

In vitro evaluation of ceftazidime antimicrobial activity in infections caused by burn and its comparison to the other antibiotics is presented. In vitro tests for susceptibility to ceftazidime and other antibiotics were carried out on 744 bacterial strains collected from burn infections. The results have shown that generally ceftazidime was more active against Pseudomollas aeruginosa an...

results the results obtained for each drug were compared with other drugs and also with the results of the control groups. the results related to promastigote and amastigote assays showed that when the dose of both drugs increased, the parasite number is reduced in comparison with the control groups. moreover, the parasitic burden in the test cultures decreased significantly. macrophage assay r...

objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...

traumatic brain injury (tbi) is caused by rapid deformation of the brain, resulting in a cascade of pathological events and ultimately neurodegeneration. in vitro models of tbi can help us to describe the pathobiological mechanisms. in vitro models of brain injury support a platform for performing repeatable, well-controlled, environmentally isolated experiments. other advantages of in vitro mo...

Aztreonam is a new monobactam antibiotic which is highly active against aerobic Gram negative bacilli. The purpose of this study is to establish the in-vitro activity of aztreonam against recent clinical isolates of aerobic Gram negative bacilli obtained from patients at the Kuala Lumpur General Hospital. Minimum inhibitory concentrations of the antibiotic against the isolates were determined u...

Background Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection (ICSI) in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogon...

A study was conducted to investigate the effect of follicular size (small,
