Abstract

Autoimmune thyroiditis (AITD) merupakan penyakit autoimun pada kelenjar tiroid. Tujuan penelitian ini adalah mengetahui profil regulasi hormon tiroid, profil siklus estrus dan folikulogenesis pada tikus model hypothyroidism hasil induksi capra thyroglobulin (cTg). Pembuatan tikus model hipotiroid dilakukan dengan injeksi dengan protein cTg yang sudah diemulsi complete freund's adjuvant (CFA)  dengan dosis 200µg/µL melalui subkutan, selanjutnya dilakukan booster injeksi protein cTg yang sudah diemulsi incomplete freund's adjuvant (IFA) dengan dosis 200µg/µL melalui subkutan sebanyak dua kali setiap 12 hari. Serum tikus diambil untuk mengetahui tikus sudah mengalami kondisi hipotiroiditis. Tikus yang sudah mengalami hipotiroid, diamati siklus estrusnya sebanyak tiga kali siklus estrus dan setiap satu kali pengulangan siklus estrus diambil serum darah untuk diukur kadar hormon tiroksin (T4) dan thyroid stimulating hormone (TSH). Pada akhir tahapan penelitian, tikus dibedah dan dikoleksi organ ovarium untuk pembuatan preparat histologi. Hasil penelitian menunjukkan bahwa induksi cTg pada tikus menyebabkan tiroiditis dan selanjutnya mengakibatkan kondisi hipotiroid yang ditandai dengan penurunan kadar hormon tiroksin dan peningkatan thyroid stimulating hormone (TSH) selama tiga kali siklus estrus. Tikus hipotiroid mengalami periode siklus estrus yang lebih panjang dan penurunan jumlah folikel de graff dibandingkan dengan tikus normal.

Abstract

Background Enhancing stimulation efficiency in mice supports the application of assisted reproductive technologies (ART) for species conservation. Objective This study compared the stimulatory potential of two ART-supporting hormone protocols: the conventional PMSG-hCG combination and recombinant gonadotropins (rFSH-rhCG), a newer generation produced by genetic engineering. Methods Sixty-three female mice from four distinct estrous phases were used in this study. Both hormone regimens, with FSH- and LH-like activities, were administered sequentially between 4:00 and 5:00 pm, at a 47–48 h interval. Stimulation success was evaluated based on the proportion of females showing a positive response and the number of oocytes retrieved. Results The diestrus phase yielded the highest response for both treatments. Approximately 60% of the females responded to PMSG-hCG, and 80% responded to recombinant hormones. The number of oocytes recovered reached 239 in the PMSG-hCG group and 137 in the recombinant group. Interestingly, recombinant hormone administration during estrus induced ovulation of 400 oocytes; however, the efficiency ratio was lower than that during diestrus (30.8 vs 34.3). Conclusion Both PMSG-hCG and recombinant gonadotropins effectively stimulate ovulation. The diestrus phase provides the most consistent results; therefore, diestrus is recommended as the optimal stage for superovulation protocols in mice.
