Polarized light is the light in which all the rays vibrate in one plane. A polarizing microscope has two disk accessories. They are made up of polarizing plastic that allows light vibrating in one plane to pass. One of them is called a polarizer (placed below the condenser). Another similar disc is placed in the top part of the microscope and cuts off all the light vibrating in a perpendicular ...
PURPOSE To study and compare the appearance of hairs from patients with Chédiak-Higashi and Griscelli-Prunieras syndromes under light and polarized light microscopy. METHOD Hairs from 2 Chédiak-Higashi and 2 Griscelli-Prunieras patients were obtained and examined under normal and polarized light microscopy. RESULTS Under light microscopy, hairs from Chédiak-Higashi patients presented evenly...
Malaria remains a major global health burden, and new methods for low-cost, high-sensitivity, diagnosis are essential, particularly in remote areas with low-resource around the world. In this paper, a cost effective, optical cell-phone based transmission polarized light microscope system is presented for imaging the malaria pigment known as hemozoin. It can be difficult to determine the presenc...
Amyloid involvement of the tongue is almost always secondary to systemic amyloidosis. Isolated amyloidosis of the tongue is relatively rare and it accounts for less than 9% of all types of amyloidosis. We are presenting a case of a 54-year-old male patient who complained of an enlarged tongue and bilateral multiple swellings on the lateral borders of the tongue, which had been there since one y...
