Background: It has been hypothesized that blastocyst integrin expression changes can affect the spontaneous miscarriage in polycystic ovarian syndromes (PCOS).
Objective: In this study, the profile of integrin genes and proteins was investigated on blastocyst of the PCOS experimental mouse model.
Materials and Methods: 30 NMRI female mice were equally divided into 3 groups: control, experimental [PCOS that was injected estradiol valerate (40 mg/kg)]. After 8 weeks, each group was hyper stimulated by PMSG and HCG. Vaginal plaque was checked, and mice were investigated 5 days after the test. Progesterone and estradiol levels were determined; α4, αv, β1 and β3 integrin genes and protein of blastocysts were examined by real time PCR method and immunohistochemistry, respectively.
Results: Estradiol level was significantly increased (p≤0.035) in PCOS group. Based on our finding, the ratio of genes' expressions αv, β3, β1 and α4 in PCOS to control group was 0.479±0.01, 0.5±0.001, 2.7±0.4 and 1.023±0.2 respectively. Genes expression showed a great difference (p≤0.001) between β3, β1 and αv in PCOS compared to other groups. αv and β3 integrin proteins expressed in all groups but intensity of these proteins in PCOS groups, was lower than other groups.
Conclusion: Pattern of αv and β3 integrins expression on the mouse blastocyst surface has an important effect during the implantation window. This pattern has changed in PCOS model and might have a great influence on implantation failure. Therefore, this experimental study suggests that a great attention to this problem may be essential in patients who are involved.

Background: Endometriosis influenced by both genetic and environmental factors. Associations of glutathione S-transferases (GSTs) genes polymorphisms in endometriosis have been investigated by various researchers; however, the results are not consistent.
Objective: We examined the associations of GSTM1 and GSTT1 null genotypes and GSTP1 313 A/G polymorphisms with endometriosis in an Iranian population.
Materials and Methods: In this case-control study, 151 women with diagnosis of endometriosis and 156 normal healthy women as control group were included. The genotyping was determined using multiplex PCR and PCR- RFLP methods.
Results: The GSTM1 null genotype was significantly higher (p=0.027) in the cases (7.3%) than the control group (1.3%). There was no significant difference between the frequency of GSTT1 genotypes between the cases and controls. The GSTP1 313 AG genotype was significantly lower (p=0.048) in the case (33.1%) than the control group (44.4%).
Conclusion: Our results showed that GSTM1 and GSTP1 polymorphisms may be associated with susceptibility of endometriosis in Iranian women.

Background: Prenatal drug exposure, as a common public health concern, is associated with an increased risk of adverse effects on early embryo development.
Objective: To investigate the in vitro development of - embryo from experimentally Kerack-addicted mice.
Materials and Methods: Twenty-five female mice were studied in five groups: control, vehicle, and three experimental groups of Kerack-dependent mice (I, II, and III) which received different doses of Kerack for 14 days. After the establishment of addiction model (7 days), experimental groups I, II, and III were given Kerack intraperitoneally at the doses of 5, 35, and 70 mg/kg, twice a day for a period of 7 days, respectively. The vehicle group received normal saline and lemon juice whilst the control group just received water and food. Morulae were obtained through oviduct flashing. The survived embryos were cultured in T6+ 5mg/ml bovine serum albumin. The developmental rates up to hatched stage daily and embryo quality (differential staining and Tunnel staining) were also assessed
Results: The developmental potential of embryos obtained from the addicted mother was significantly decreased in comparison with control group. There was a significant reduction in the rate of blastocyst formation in the high dose Kerack dependent group. However, in addicted mice there was reduction in the total cell number (40.92% vs. 65.08% in control) and, inner cell mass percentage (17.17% vs. 26.15% in control) while apoptotic cells numbers were increased (7.17 vs. 1.46 in control) (p<0.05).
Conclusion: The Kerack addiction during pregnancy retards preimplantation development and induces apoptosis.

Background: common use of sevoflurane in congenital defects during repeated surgeries may have detrimental effects on spermatogenesis after puberty.
Objective: This study investigated sevoflurane effects on spermatogenesis process in male mature mice after exposure in prepubertal time.
Materials and Methods: 24 neonatal NMRI male mice were randomly classified in three groups. Experimental 1 and 2 groups (exposure to 1 minimum alveolar concentration (MAC) and 2 MAC sevoflurane, respectively in 2 lit/min oxygen (O2) for 7 days (30 min, daily) and control. All groups were sacrificed after 2 months. Histological assessment, immunohistochemistry and apoptosis process was done. Bax and Bcl2 expression was evaluated in the testicular tissue by real time Poly Chain Reaction.
Results: Our results showed that the integrity of testicular tissue was preserved in both experimental groups. Count of spermatogonial cells had significant decrease in group 2 compared to others. The rate of apoptosis in spermatogonial cells was 15±3% and 9±2% in the group 2 and 1, respectively. Also, Bax/Bcl2 ratio was 0.2615, 1.0070 and 9.3657 in control, experimental group 1 and 2, respectively. This result was significant (p≤0.002) between groups 2 with other groups.
Conclusion: Continuous exposure of 2 MAC sevoflurane in 2 lit/min O2 simultaneous during prepubertal may create more testicular tissue damage in terms of cellular and molecular function compared to continuous exposure to lower level of sevoflurane by increase in ratio of Bax/Bcl2 and apoptosis in germ cells after puberty.
