PURPOSE To evaluate the efficacy and safety of two oscillating/rotating toothbrushes, (Braun Oral-B Plaque Remover-D7 and Braun Oral-B Ultra Plaque Remover-D9) and a manual toothbrush with respect to removing extrinsic dental stain. MATERIALS AND METHODS This randomized, three-way cross-over study investigated 24 subjects entering the trial, which was divided into three, 5-day periods. Over t...

Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains and dyes are frequently used in biology and medicine to highlight structures in biological tissues for viewing, often with the aid of different microscopes [1]. Hematoxylin and eosin stain (H&E stain or HE stain), is the routine staining for skin biopsies. However, in some circumstances, d...

According to WHO one third of the world population have tuberculosis. The present study was undertaken to compare the efficacy of flurochrome(FI) stain with conventional Z-N stain in the diagnosis of pulmonary & extrapulmonary tuberculosis. 388 cases of suspected pulmonary tuberculosis were included in the study. All samples were screen for Acid Fast Bacilli (AFB) by Z-N & Fluorescent staining ...

Figure. Transverse section of an Armillifer armillatus larva from the liver of the patient (immigrant) from Togo. Typical for pentastomid lesions, the parenchyma shows focal hemorrhage around the parasite and no inflammatory cellular reaction (1). There is also focal destruction of the trabecular liver parenchyma. Subcuticular gland cells of the parasite are visible, and the intestine is clearl...

BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) can result in peptic ulcer disease (PUD) which is a common condition worldwide. The aim of this study was to evaluate the antiulcer properties of (1-(4-hydroxy-phenyl)-3-m-tolyl-propenone) (HPTP) chalcone in rats using indomethacin as ulcerogenic agent. RESULTS None of the rats showed symptoms of kidney and liver toxicity during the te...

OBJECTIVE The aim of this study is to compare the impact of two different loading conditions on myocardial contractility in asymptomatic patients with normal EF by using stain rate imaging (SRI). METHODS A total of 27 patients with severe aortic regurgitation (mean age 50 ± 11 years) and 25 patients with severe aortic stenosis (mean age 53 ± 15 years) were prospectively recruited. Fifteen hea...

Analysis of the mechanism of Gram differentiation by use of a filter-paper chromatographic technique. J. Bacteriol. 90:766-777. 1965.-Data are presented which demonstrate that the mechanism of gram-positivity could not be due solely to factors such as a single, specific gram-positive substrate...

Pulsed dye laser (PDL) is an effective treatment for port- wine stain and can cause some short- term and long- term side- effects. Pyogenic granoluma is one of its late- onset adverse effects. Herein, we present two cases of pyogenic granoluma following treatment of port- wine stain with PDL.

Introduction: Barr body is of the X chromosomes formed from random inactivation and condensation of one of the two female chromosomes in virtually all the somatic cells of female mammals. In practice stains such as Papanicolaou, and carbol fuchsin, have proved suitable because they produced stronger contrast and are much simple to manipulate. Aim: Our study aimed to assess the efficacy of gende...

OBJECTIVE Cryptosporidium spp. is obligatory intracellular parasite and causes intestinal infection. In intestine infections in the form of sporadic and epidemics, food and accordingly workers in food sector may play a role as the source of infection. In this study, it is aimed to reveal the existence of asymptomatic cryptosporidiosis. METHODS In the study, stool samples of 393 workers -emplo...
