Notes: Abstract In a previous study, it was demonstrated that heat shock protein 70 (hsp70) was induced by short duration (〈1 s) carbon dioxide (CO2) laser radiation (10.6Μm. To further characterize the stress response after laser irradiation, the time course of synthesis and cellular localization of hsp70 has been followed. As it had been shown that laser irradiation elevated the temperature to about 67±2

Notes: Microscopic examination of adipocytes isolated from adult rat epididymal adipose tissue revealed numerous small cells (〈 10 μm) morphologically similar to larger adipocytes. These small adipocytes appear identical to a new classification of adipose cells termed preadipocytes. Electron micrographs of these preadipocytes revealed examples of cells 〈 10 μm in diameter in various stages of maturation and lipid accumulation. The percent distribution pattern of these small adipocytes was not significantly altered by exercise although exercise shifted the distribution patterns of the larger cells (〉 30 μm) toward a smaller mean cell size. The quantitative significance of preadipocytes is not established but these preliminary observations indicate that adipocytes 〈 10 μm in diameter may account for a numerically greater proportion of the total adipocytes observed in collagenase isolated preparations than heretofore recognized, although their contribution to total adipose mass is probably negligible.
