五、图片效果
Fig. 1A-C. Figure 1A is a micrograph of a normal sural nerve with a non-myelinated nerve (N) having secretory vesicles (sv), microtubules (mt) and a swan cell nucleus (ScN). The insert (1B) shows a myelinated nerve and the arrows clearly demonstrate its periodicity. Figure 4C is a membranouse Lupus nehpritis (RPS/ISN Class V). There is diffuse, generalized effacement of the foot processes of the visceral epithelial cells. Numerous regularly disposed epimembraneous immune complex deposits are illustrated by the arrows. Both tissues were initially fixed in a variant of 10% NBF (Carson et al. 1972) and then processed in the microwave for ultrastructural evaluation by the methods of Giberson et al. (2003) and Austin (2002). Micrographs from Ronald L. Austin, Research Associate, Dept. of Pathology, LSU Medical Center, Shreveport, LA 71130.
Figure 2A-G. Fig. 2A-B shows cytoplasmic iridovirus from the skin of a sturgeon. The iridovirus is a large enveloped dsDNA virus which infects both insect and vertebrate hosts. Fig. 2C-E demonstrates an intranuclear baculovirus from the hepatopancreas of a crayfish from Northern California. Fig. 2C is a low magnification image of the enveloped dsDNA virus showing the intranuclear arrangement of virus particles Fig. 2D is a higher magnification showing both a cross-sectional and longitudinal view of the virus. Fig. 2E is a high magnification cross-section of a number of virus particles demonstrating the unique intranuclear membrane-bound virions. Fig. 2F-G demonstrates an endothelial cell polyoma virus from a blood vessel in the liver of a parakeet. Polyoma virus have a single molecule of circular dsDNA and the particles are non-enveloped. Polyoma virions are spherical in outline and typically 45nm in diameter. Fig. 2F is a low magnification image showing typical nuclear presentation. Fig. 2G is a high magnification view of the virus. Infected tissues were processed directly from 10% NBF by the microwave methods of Nordhausen and Barr (2001) and Nordhausen et al. (2002). Micrographs from Bob Nordhausen, Univ. of California, Davis, California Animal Health and Food Safety Lab, School of Veterinary Medicine, Davis, CA 95616.
Figure 3. Micrographs from a 2008 microwave workshop held at the Center for Microscopy, San Joaquin Delta College, Stockton, CA. Rat brain (not perfusion fixed) (1), cardiac muscle (2), kidney (3) and liver (4) were processed from osmium through resin polymerization for a net turnaround time of under 4 hours from fresh tissue to the electron microscope. Microwave techniques (Giberson, et al., 2003) make it possible to teach and in real time demonstrate the techniques of electron microscopy.
Figure 4A-F. Figures A-C are of normal mouse liver benched fixed in 10% NBF for 24 hours. Figures D-F are of normal mouse liver fixed in 10% NBF for 20 minutes utilizing microwave radiation. All tissues were prepared for fixation identically and cut to 2mm prior to fixation. Figures A and D are corresponding Hematoxylin and Eosin stained sections and figures B and E are corresponding Vimentin IHC stained sections. Figures C and F are corresponding EM sections demonstrating complimentary ultra-structure. Images are from Dr. Jose Galvez, Center for Comparative Medicine and Department of Medical Pathology, University of California, Davis, CA.

Figure 7. Retinas were fixed in 4% paraformaldehyde in 0.1M phosphate buffer (pH 7.4) overnight at 4°C. Following fixation the tissue was rinsed 6 x 20 minutes in buffer prior to beginning antibody labeling. The bench staining protocol required 7 days. The labeling results were completed in an afternoon using microwave-enhanced labeling during a workshop held at the Univ. of Minnesota Imaging Center (Mark Sanders, Director - May 17-19, 2006). The retinas were triple-labeled for:
Primary antibody labeling was done at 170W for 12 minutes (4 on - 4 off - 4 on) under vacuum (15" Hg). Secondary antibody labeling was done at 170W for 6 minutes (2 on - 2 off - 2 on) under vacuum (15" Hg). Images were collected on a Nikon C1si Confocal Microscope.
Figure 8. Note the symmetrical pattern of demineralization when microwave methods are employed. The separated piece at the top broke off during plastic embedding. From the work of Steven P. Tinling (Tinling et al., 2004), Otolaryngology Research Laboratory, University of California, Davis 95616.
Figure 9. Left Image. Image on the left is an electron micrograph of an inner hair cell (IHC) and supporting cells (S) from a Japanese macaque monkey. The lower left arrow indicates the region shown at higher magnification in the image to the right. Bar = 3.0µm. Right Image. In the supporting cells next to the inner hair cell, the rough endoplasmic reticulum and microtubules are well-preserved. Bar = 0.5 µm. Reprinted with permission from Madden and Henson, 1997.
