To further understand the pathogenic changes of the diseased crab, the ultrathin sections
of tissues of the diseased crab sampled from the farms were examined with transmission electron microscopy.
In a first analysis of ultrathin sections
from hearts of the same rats, we found ultrafine Ti[O.
In ultrathin sections
, groups of poxlike virions were readily seen within cytoplasm of infected hepatocytes (Figures 2A and B).
Second ultramikrotom for preparation of ultrathin sections
of frozen samples and specimens embedded in resin;
The ultrathin sections
of infected Vero cells were observed through transmission electron microscopy (Hitachi H7000).
were stained in ethanolic uranyl acetate and lead citrate and examined by electron microscopy (JEM-200 FX; JEOL, Tokyo Japan).
second ultramikrotom for preparation of ultrathin sections
from frozen samples and specimens embedded in resin;
were stained with 4% uranyl acetate and Reynold's lead citrate.
were made from areas selected under light microscope and analyzed under a Philips 400-T model electron microscope (Philips Nederland B.
1 of the Act is a public contract is divided into 2 parts - Part 1 Public Procurement: an automatic process in situ hybridization,- Part 2 Public Procurement: Rotary microtome for ultrathin sections
In this manner, ultrathin sections
were obtained in planes that were parallel and perpendicular to the growth surface.
