ABSTRACT
<p><b>OBJECTIVE</b>To explore the mechanism of Er'zhi Tiangui Granule (ETG) in improving the quality of oocyte.</p><p><b>METHODS</b>Ninety mice were randomly divided into 6 groups. The number of high-quality oocytes was comparatively observed in the 1st experimental group and the 1st control group; the embryonic cleavage rate was observed in the 2nd experimental group and the 2nd control group and the quantity of insulin-like growth factor-1R mRNA (IGF-1R mRNA) expression in ovarian granular cells was determined by using in situ hybridization in the 3rd experimental group and the 3rd control group.</p><p><b>RESULTS</b>The high-quality oocytes rate, the embryonic cleavage rate and the quantity of IGF-1R mRNA expression in the three paired groups was (78 +/- 8)% vs (71 +/- 5)%, (88 +/- 3)% vs (83 +/- 5)%, 0.4890 +/- 0.0454 vs 0.4439 +/- 0.0283, respectively. The difference between the experimental groups to the respective control groups was significant (all P < 0.05), and positive correlation was shown between the high-quality oocytes rate and the quantity of IGF-1R mRNA expression.</p><p><b>CONCLUSION</b>The mechanism of ETG in improving the quality of oocyte may be related with the elevation of IGF-1R mRNA level in ovarian granular cells.</p>
