“Hydropic degeneration” of the hepatocytes are often found in biopsy of the liver of some kinds of viral hepatitis. Light microscopic observation, compareted with the normal hepatocytes, they are enlarged, sometimes to a marked degree when the term “balloning” degeneration is used. Their cytoplasm rarefied, and show some clearness in the peripheral cytoplasm, so, it causes a hydropic appearance, the cytoplasm around the nuclei is granulated. Up to the present, many studies belive that main ultrastructural chenges of hydropic degeneration of the hepatocytes are results of the RER cristae dilatation with degranulation and disappearance of glycogen granules.The specimens of this study are fixed with the mixed fluid of the osmium acidpotassium of ferricyanide, Epon-812 embed. We have observed 21 cases of biopsy specimens with chronic severe hepatitis and severe chronic active hepatitis, and found that the clear fields in the cytoplasm actually are a accumulating place of massive glycogen. The granules around the nuclei are converging mitochondria, endoplasm reticulum and other organelles.

We have cultured mesenchymal cells (MSC) on various types of ceramic disks and used these tissue-engineered ceramics for hard tissue regeneration. In this approach, observation of cultured cell morphology is important even if culture substrata are calcium phosphate ceramics, which usually show bioactive nature. However, due to the opaque nature of the ceramics, cells observation is very difficult. Here, we demonstrate light microscopic observation of rat MSC cultured on transparent β-tricalcium phosphate ceramics (β-TCP). The culture was performed in osteogenic medium. Thus, the cell differentiated into bone-forming osteoblasts, which fabricated a mineralized matrix on the ceramic disks. Microscopic observation revealed that the cascade of osteogenic differentiation after attachment/proliferation of MSC on the ceramic disks was similar to that on a culture grade polystyrene dish. These results confirmed the excellent property of β-TCP for MSC culture leading to hard tissue regeneration.
