OBJECTIVE: The present study was performed to investigate the efficiency of partial laser assisted hatching (p-LAH; lased 1/2 ZP width from ZP edge) on hatching of mouse blastocysts. METHODS: We used non-contact 1.48 micrometer diode laser (MTM, Switzland) to create a precise hole on zona pellucida. 2-cell embryos were collected from the mouse (ICR) oviduct at 48 hours after hCG administration. Collected 2-cell embryos were cultured in the P-1 medium supplemented with 0.4% BSA. For experiments, embryos at 8-cell stage were used after 20~22 hours in culture. After conventional (c-LAH) or partial laser assisted hatching, the embryos were further cultured in P-1 medium supplemented with 0.4% BSA for 3 days. To compare efficiency of complete and partial laser assisted hatching, hatching rate, hatching time and blastocyst diameter and zona pellucida thickness at hatching time were investigated. Embryos were examined every 12 hours. Blastocyst diameter and zona pellucida thickness at hatching time were measured with an ocular micrometer. RESULTS: Hatching rates of p-LAH group (84.2%) was significantly higher than that of control group (39.3%), but there was no difference between the p-LAH (84.2%) and c-LAH (91.2%). p-LAH group was hatched 12 hours earlier than control group, but hatched 12 hours later than c-LAH group. The diameter of blastocyst at hatching time of p-LAH group (113.1+/-6.4 micrometer) was smaller than that of control group (122.2+/-5.0 micrometer), but larger than that of c-LAH group (102.2+/-2.7 micrometer). Zona pellucida thickness at hatching time of p-LAH group (6.4+/-0.9 micrometer) was thicker than that of control group (4.5+/-1.5 micrometer), but thinner than that of c-LAH group (10.0+/-0.8 micrometer). CONCLUSION: These results suggest that p-LAH may maintains the cell arrangement of early embryos to ensure successful development and prevent precocious hatching of blastocyst when compare to c-LAH and conventional (acidic tyrode) AH. Thus, p-LAH may provide a valuable and effective AH technique for human ART program.

OBJECTIVE: This study has been carried out to evaluation the effect of fertilization promoting peptide (FPP) on the kinematic parameters, capacitation and acrosome reaction of the frozen-thawed human spermatozoa. METHODS: After FPP treatment, we examined kinematic parameters, capacitation and acrosome reaction, using the methods of computer-aided sperm analysis (CASA) and chlortetracycline (CTC) fluorescence analysis. RESULTS: We have obtained the evidence that FPP can promote the capacitation and inhibit the spontaneous acrosome reaction of frozen-thawed human spermatozoa in vitro. Fpp (25~100 nM) induced a significant increase in the proportion of B-pattern capacitated spermatozoa, and a significant decrease in the proportion of F-pattern uncapacitated ones without significant stimulation of acrosomal exocytosis. In the kinematic parameters treatment, FPP treated groups maintained higher LIN, BCF and STR than those of control. The VAP, VSL, VCL and ALH were not different. Therefore it is suggested that FPP in human seminal plasma may play a positive role in promoting human sperm function.

OBJECTIVES: The purpose of this study is to evaluate the problem behaviors of adolescents and to discriminate between parenting behaviors of problem behavior groups and those of non-problem behavior group. METHODS: The subjects of this study were 792 high school students in Seoul. We administered 'Parenting Behavior Inventory' and Korean version of Youth Self-Report(K-YSR) to the subjects in order to evaluate the parenting behaviors perceived by adolescents and the problem behaviors of adolescents. We analyzed the relationship between parenting behaviors and problem behaviors. We classified the subjects into problem behavior groups(internalizing group, externalizing group, internalizing-externalizing group) and a non-problem behavior(normal) group. We studied the differences of parenting behaviors among the groups. RESULTS: The results are as follows. 1) There were significant negative correlations between the positive parenting behaviors such as affection, reasoning, and monitoring and the problem behaviors of adolescents. By contrast, there were significant positive correlations between the negative parenting behaviors such as physical abuse, intrusiveness, over-expectation, neglect, and inconsistency and the problem behaviors of adolescents. 2) Adolescents of the internalizing group perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Meanwhile, they perceived significantly less affection than normal adolescents. Adolescents of the externalizing group also perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Also, they perceived significantly less monitoring than normal adolescents. 3) Adolescents of the internalizing-externalizing group perceived significantly more intrusiveness from both parents than those of either the internalizing or the externalizing groups. Adolescents of the internalizing-externalizing group perceived significantly less affection and more neglect from their mothers than those of the internalizing or the externalizing groups. In addition, adolescents of the internalizing-externalizing group perceived significantly more physical abuse from their fathers than those of the internalizing or the externalizing groups. CONCLUSION: Parenting behaviors such as abuse, intrusiveness, over-expectation, neglect, and inconsistency are associated with both internalizing and externalizing problems. In contrast, our results suggest that parenting behaviors such as affection, monitoring, and reasoning might decrease the various problem behaviors of adolescents.
