The oocyte cryopreservation is more promising than embryo freezing in clinical applications,preservation of female fertility,legal and ethical aspects in this decade.The redundant oocytes retrievedfrom ⅣF cycles can potentially donate oocytes,which have unique advantages in economy and feasibili-ty.We have achieved success in embryo freezing,but just obtained poorer results in oocyte cryopreserva-tion which was mainly because of the low rates of survival,fertilization,and cleavage.The character ofthe plasma membrane and the time of cortical granules present at the metaphase of meiosis Ⅱ with thespindle system consist of the major difference between oocytes and embryos.Moreover,the oocytes shouldbe fertilized by sperm at the appropriate time.We used a refined slow freezing method to improve the sur-vival rate and increased sucrose concentration to dehydrate oocytes.Vitrification was another approach toprevent harms.Besides,intracytoplasmic sperm injection was used to overcome possible zona hardeningafter the release of cortical granules.Oocytes after cryopreservation showed serious disturbances of the mi-crotubules immediately after thawing as they were vulnerable to the thermal changes and easy to depoly-merize.Fertilization of these oocytes with disorganized spindles led to chromosomal aneuploidy,digyny,and degradation of the cleavage rate.We can improve cryopreserved oocytes to normal fertilization anddevelopment by appropriate incubation and timing of insemination,as the microtubules repolymerize in atime dependent way after incubation which is compatible with recovery of the spindles.With the improve-ment of survival,fertilization,and development,oocyte cryopreservation will play an imperative role.

BACKGROUND: The neurological basis for learning and memory is the high plasticity of central nervous system, and special rehabilitative training is necessary in the process of the functional recombination of central nervous system.OBJECTIVE: To observe the capability of rehabilitative training in differentiating learning ability and memory maintaining of one-trial passive avoidance response, and its correlation with the kinetic properties of Nmethyl-D-aspartic acid (NMDA) receptor channel of contralateral hippocampal neuron in rats with cerebral infarction.DESIGN: A randomized control animal trial.SETTING: Department of Rehabilitative Medicine, Affiliated Hospital of Luzhou Medical College.MATERIALS: The experiment was carried out in the central laboratory of Luzhou Medical College between March 2000 and February 2002. Twentyfour male Wistar rats were randomly divided into three groups with 8 rats in each: free movement after cerebral infarction group (model group), rehabilitative training after cerebral infarction group (rehabilitation group) and normal group.METHODS: ① Model establishment: Rats in the model group and rehabilitation group were made into models of infarction of right middle cerebral artery, and those in the normal group were not given any treatment. ②Rehabilitative training: After 4 days, only the rats in the rehabilitation group were trained with rolling-cage exerciser, screen exerciser and balance exerciser for 4 weeks. ③ Learning and memory tests: The learning and memory performances of all the rats were tested at 35 days postoperatively. The Y-maze test was applied to mainly observe the needed number f training for the rats to reach 9/10 correct response (for running to dark arm), and the multi-functional conditioned reflex box to observe the stayed duration on the diving board (step-through latency). ④ The single channel current property of NMDA receptor in hippocampal neurons was recorded with cell adhesion after learning and memory tests.MAIN OUTCOME MEASURES: ① training times needed for the rats to grasp the structure of the maze in each group; ② step-through latency in each group; ③ single channel current property of NMDA receptor in each group.RESULTS: All the 24 rats were involved in the analysis of results. ① The training times needed for the rats to grasp the structure of the maze in the rehabilitation group and normal group were significantly different from that in the model group [(68.02±11.67), (57.62±10.31), (107.07±16.32) times, P ＜0.05], and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ② The medians of step-through latency before shock in the rehabilitation group and normal group were significantly different from that in the model group (286.7 s, 298.4 s, 126.7 s, P ＞0.05), and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ③ The 35 pS short open NMDA receptor channel mainly existed in the hippocampal neurons of rats in the rehabilitation group, the open proportion was 0.099±0.007. The duration and proportion of 20 pS short and long open and the 35 pS short open NMDA receptor channels in the hippocampal neurons of rats were not significantly different from those in the normal group (P＞0.05). In the model group, 20 pS open channel was mainly observed, and the durations of 20 pS short and long open channels were obviously shorter than those in the rehabilitation group, the open proportion of 35 pS short open channel was 0.036t0.04, which was lower than that in the rehabilitation group,but no 35 pS long open channel was observed.CONCLUSION: Rehabilitative training accelerates the recovery of the learning and memory abilities of rats with cerebral infarction by changing the NMDA receptor channel properties of contralateral hippocampal neurons.

Objective:To study the optimal process of reflux extraction for lignans from Acanthopanax sessiliflorus roots. Methods:Sesamin as the reference substance, a colorimetric method was used to detect the absorption value of the samples at 558 nm to calculate the content directly. The extraction time, the extraction times and the volume of extraction solvent were applied to optimize the extrac-tion conditions for total lignans by orthogonal experiment. Results:The absorbance had a linear relationship with the amourt of sesamin within the range of 10. 6-53. 0 μg·ml-1(r=0. 999 7). The average recovery of sesamin was 102. 2%(RSD=1. 6%, n=6). The content of total lignans (measurement by sesamin) in the extracts was 10. 0 mg·g-1. The optimum reflux extraction conditions were as follows:adding 40-fold 50 % methanol, extracting once for 30 min. Conclusion:The UV method for determining the total lignans is feasible, stable and reliable as well as precise, and the optimal extraction process is reasonable.
