The efficacies of SH and CMC were equivalent in treating mild to moderate dry eye. SH and CMC preservative-free artificial tear formulations appropriately manage dry eye sign and symptoms and show safety and efficacy when frequently administered in a unit dose formula.
ObjectiveThe aim of this study is to evaluate in vitro fertilization (IVF) outcomes in advanced endometriosis with/without surgical treatment and to compare between cyst enucleation and surgically treated peritoneal lesions without endometrioma.
MethodsWe performed a retrospective analysis of 506 IVF cycles (345 patients) with stage III-IV endometriosis (170 cycles without surgical treatment, 336 cycles with the surgical treatment) between 1997 and 2004. Among the surgical treatment, 151 cycles were performed previously cyst enucleation with endometrioma and 185 cycles were performed only resection of peritoneal lesions without endometrioma enucleation. 313 cycles (246 patients) with the tubal factor infertility were used as controls.
ResultsIn the endometriosis group with/without surgical treatment, the number of retrieved oocytes (9.6±7.3 vs. 11.2 ± 7.5 vs. 14.8 ± 7.0, P < 0.0001) and the transferred embryos (3.5 ± 1.4 vs. 3.5 ± 1.4 vs. 3.9 ± 0.9, P = 0.001) was significantly lower than controls. But, implantation rates (17.2% vs. 15.2% vs. 15.9%), pregnancy rates (36.9% vs. 35.9% vs. 39.6%) and live birth rates (32.1% vs. 28.2% vs. 29.7%) were similar. Surgically treated peritoneal lesions group showed no difference in the number of retrieved oocytes (9.6 ± 7.9 vs. 9.8 ± 6.5), the number of transferred embryos (3.4 ± 1.4 vs. 3.7 ± 1.3), implantation rates (15.5% vs. 18.0%), pregnancy rates (34.6% vs. 39.7%) and live birth rates (29.2% vs. 35.8%) with cyst enucleation group.
ConclusionIVF parameters in the patients with endometriosis are inferior to tubal factor infertility, but IVF outcomes are comparable. Surgically treated peritoneal lesions group without endometrioma enucleation shows IVF parameters as bad as cyst enucleation group. We might be considered endometriosis itself worse IVF parameters regardless previous cyst enucleation. Korean J Obstet Gynecol 2011;54(9):517-522 http://dx

ObjectiveWe aimed to evaluate the effect of prednisolone (PDS) on natural killer cell (NK cell) cytolytic activity in vitro.
MethodsBlood samples from 74 patients with history of unexplained recurrent spontaneous abortion who elevated peripheral blood NK cell fraction were collected prospectively. Peripheral blood monocytes which containing NK cells were isolated and separated to three different tubes which containing target (K562) cells by the 50:1 effector to target (E:T) ratio. PDS or intravenous immunoglobulin (IVIG) was additionally added to 2 tubes for evaluate their suppressive effect. The percentage killing of target cells was recorded numerically by using fl ow cytometer and the values between groups were statistically analyzed.
ResultsThe mean target cell killing percentage was 40.5% in co-culture tube which was not added PDS or IVIG. In culture experiments which was added IVIG, the killing percentage is reduced to 37.7% which showed no signifi cant differences compared to that of co-cultured tube which was not added PDS or IVIG. But, in experiments with added PDS, the killing percent was reduced to 19.5% and the difference was statistically signifi cant (P<0.001) compared to that of co-cultured tube which was not added PDS or IVIG. On comparing the reduction in killing percentage of target cells by PDS and IVIG, statistically signifi cant reduction in the PDS coculture was noted (P<0.005).
ConclusionNK cell cytolytic activity is effectively down-regulated by using PDS in vitro. Moreover, the effect of PDS in down-regulation of NK cell cytolytic activity is seems to superior than that of IVIG. But, large scaled in vivo study is needed.
