Cyclophosphamide가 생쥐 정소의 Leydig Cell에 미치는 영향
정해만,김정상,조광필,Jung, Hae-Man,Kim, Jeong-Sang,Cho, Kwang-Phil 한국현미경학회 1995 Applied microscopy Vol.25 No.2
This research was undertaken to determine the effect of cyclophosphamide(CP) on the Leydig cells and macrophages in the interstitial tissue of the mice(ICR strain). To evaluate how this drug could affect the these cells, during administration(200mg/kg) 1 time to 3 times at intervals of 48hrs. In the Leydig cells of the control and 1 time treated group, a number of microperoxisomes were observed interspersed among the network of smooth endoplasmic reticulum(SER) in cellular regions where the SER predominantes. Microperoxisomes were also founded in close proximity to the cell membrane. The interstitial tissue were exhibited degenerating Leydig cells but macrophages wer containd greatly increased numbers of cytoplasmic inclusion body and secondary lysosomes. In the 1 time treated group. A very small number of Leydig cells were observed, from 2 to 3 time group, but macrophages were more increased than 1 time group in number. CP thus offers a valuable opportunity to study further the interaction between Leydig cells and macrophages in the interstitial tissue. These alteration could be direct mediated by toxic effect of the drug on the interstitial tissue.
Alkylating agent가 생쥐 정소의 Sertoli Cell에 미치는 영향
정해만,조광필,김정상,Jung, Hae-Man,Cho, Kwang-Phil,Kim, Jeong-Sang 한국현미경학회 1996 Applied microscopy Vol.26 No.3
This paper aims to probe that the effect of high dose of cyclophosphamide to the Sertoli cells of the mouse was examined by transmission electron microscope. In the normal group, Sertoli cells contact each other around the basal aspect of the seminiferous tubule, forming numerous row of tight junction, blood-testis barrier. Sertoli cells contain smooth endoplasmic reticulum, well developed Golgi comples, a number of round mitochondria and microfilament. The cytoplasmic necrosis are observed from the 1-time treated group. In the 2-times treated group, smooth endoplasmic reticulum are more developed than normal group, but cisternae are partially dilated. In the 3-times treated group, the smooth endoplasmic reticulum are not developed. In the 2-times treated group, the inner membrane of the mitochondria are partially disrupted, and cristae are all disrupted in the 3-times treated group. The microfilaments are not observed in the all treated groups. According to the results above, it seems that smooth endoplasmic reticulum, mitochondria, and microfilament are disrupted by toxic effects of the cyclosphamide to the Sertoli cells of the mouse.
