The in vitro effects of artesunate, the antimalarial agent, and metronidazole against Acanthamoeba spp were studied. Acanthamoeba Group II and Acanthamoeba polyphaga-like were isolated from natural water courses in Buri Ram Province, northeastern Thailand. The trophozoites were axenically cultured in PPYG medium and treated with artesunate in a concentration of 5-700 microg/ml. Artesunate showe...

This study was performed to evaluate the effects of fibroblast co-culture on in vitro maturation (IVM) of prepubertal mouse preantral follicles. The intact preantral follicles were obtained from the ovaries of 12-14 day old mice and these were cultured individually in α-minimal essential medium (α-MEM) supplemented with 5% fetal bovine serum (FBS), 100 mIU/Ml recombinant follicle stimulating ho...

PURPOSE To evaluate the effect of bevacizumab on the mitochondrial function of human retinal pigment epithelial (ARPE-19), rat neurosensory retinal (R28) and human microvascular endothelial (HMVEC) cells in culture. MATERIALS AND METHODS ARPE-19 and R28 cells were treated with 0.125, 0.25, 0.50 and 1 mg/ml of bevacizumab. The HMVEC cultures were treated with 0.125, 0.25, 0.50 and 1 mg/ml of b...

OBJECTIVE To determine the frequency and compare the culture yield of bacterial isolation by conventional and blood culture BACTEC bottle techniques in cirrhotic patients with spontaneous bacterial peritonitis (SBP). STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY Pathology Department, Bannu Medical College, Bannu, KPK, from January 2012 to December 2013. METHO...

Early-bactericidal-activity (EBA) studies measure the change in mycobacterial load in sputum over time to evaluate antituberculosis drugs. We investigated whether a delay in sputum processing influences the quantitative results of sputum mycobacterial culture. We identified pretreatment smear-positive sputum samples collected overnight and processed at a single laboratory. Sputum volume, time f...

BACKGROUND A better understanding of the epidemiology of nasopharyngeal carriage of Streptococcus pneumoniae is important to assess the impact of vaccination and the pathogenesis of pneumococcal disease. We compared the recovery of S. pneumoniae from nylon flocked, Dacron and rayon swabs. METHODS The recovery of S. pneumoniae from mocked specimens using flocked, Dacron and rayon swabs were co...

In Exp. 1, Medium 199 and Medium RD (RPMI-1640 and Dulbecco's MEM, 1:1 v/v) were compared in a 2 x 2 factorial design by supplementing each with 15 mg bovine serum albumin (BSA)/ml of 1 mg polyvinyl alcohol (PVA)/ml. All media contained 5 micrograms insulin/ml, 5 micrograms transferrin/ml, 5 ng selenium/ml (ITS), and 10 ng epidermal growth factor (EGF)/ml. One-cell embryos were cultured at 39 d...

Objectives: To explore the effects of cyclosporine (CsA) on skeletal development (chondro­ genesis). Anatomy Department, Shiraz Materials and Methods: Mesenchymal cells obtained from stage-23 to stage-24 chickUniversity of Medical embryo limb buds were grown in 96-well plates using chemically defined tissue-culture Sciences, Shiraz, Iran. medium. Cultures were treated with CsA (0.01–5.0 μg/ml) ...
