Abstract

|
|
This experiment was carried out to observe early morphological changes of luteal cells in Korean native cattle treated with prostaglandin F2alpha. Twenty five gram of prostaglandin F2alpha was administrated per cow at 10 days after ovulation and luteal cells were removed 30, 60, 120 and 180 minites after administration. Morphological changes of each luteal cell was observed by electron microscope. the results obtained were summarized as followings: 1. Many electron-dense granules were observed in luteal cells obtained from control cow but those granules were decreased rapidly after 30 minutes of administration and no granules were obresved after 180 minutes of administration. 2. In control, the shape of mitochondria were begining to collapse from the time of 60 minutes after administration. After 180 minutes of administration, mitochondria were swelled extreamly. 3. Lipid droplets in luteal cell were increased in its size and number with the duration of time after administration. 4. Shape of smooth endoplasmic recticulum was vesicular and its dimension and number were increased according to time course after administration.
