In present study

optic and electron microscopes were used to observe the fat tissue

small intestinal mucosa and liver tissue of obese rat. The results showed that as compared with normal rat there were many morphological changes in the obese rat. The brown fat cells were enlarged

full and fat drops enlarged too

the number of mitochondrion and blood capillary decreased in obese rat. After acupuncture treatment

above changes reversed markedly. This paper provided one of important morphological bases for acupuncture antiobesity which was achieved by enhancing energy consumption and reducing energy intake.
