Abstract :

This study was aimed � � � � � � � � � � � � � � � � � to explain pathogenesis of occurring ovarian cyst and ovulation disturbance in PCOS case. This study is an experimental study using Rattus novergicus as PCOS model, compared to control study in every estrus cycle phase of Rattus novergicus, ie, proestrous, estrous, metestrous and disestrous phase. Each study group and control group consisted of 5 rats so that there were a total of 25 Rattus novergicus. PCOS model group was injected with testosterone propionate with dose 1mg/ 100 BW, whereas control group with propylene glycol injection. The examination of MMP-9, TIMP-1 activity by ELISA activity and Collagen-4 used immunohistochemistry staining. The statistic analysis used ANOVA test. The average of MMP-9 activity of PCOS model (P): 235.17 (SD: 5.47), Proestrous Group (PG): 257.40 (SD: 0.25), Estrous Group (EG): 262.80 (SD: 2.34), Metestrous Group (MG):254.43 (SD: 6.21), Diestrous Group (DG):240.69 (SD: 4.16). With ANOVA test, PCOS model only indicated a significant difference with Estrus Group: (p = 0.001). The average of TIMP-1 activity of P: 57.15(SD: 2.46), PG: 51.63(SD: 3.81), EG: 16.30 (SD: 2.33), MG: 12.84 (SD: 0.42 ), DG: 28.95 (SD: 3.07). With ANOVA test, PCOS model indicated a significant difference with Estrus, Metestrus and Diestrus (p = 0.000).The average of Collagen – 4 expression P: 41.60 (SD: 3.36 ), PG: 22.40 (SD: 3.51), EG: 21.40 (SD: 1.52), MG: 23.80 (SD: 1.92), DG: 23.80 (SD: 1.79) with ANOVA test indicated a significant difference (p = 0.00). The decrease of MMP-9 activity and the increase of TIMP-1 activity occuring in PCOS model have resulted in the increase of Collagen 4 expression and finally caused the thickening fibrous follicle wall consequently, the failure of follicle enlargement may mechanically occur.
