Since 2002, we h.ve been observing th. mesosph.re and lower th.rmosph.re （MLT） region over King Sejong Station （KSS; 62.22°S, 58.78°W）, Antarctica, using various instruments such.as th. Spectral Airglow Temperature Imager （saTI）, All Sky Camera （ASC） and Vh. meteor radar. Th. meteor radar, installed in March.2007, continuously measures neutral winds in th. alti- tude region 70-110 km and neutral temperature near th. mesopause 24 h.d-1, regardless of weath.r conditions. In th.s study, we present results of an analysis of th. neutral wind data for gravity wave activity over th. tip of th. Antarctic Peninsula, wh.re such.activity is known to be very h.gh. Also presented is temperature estimation from measurement of th. decay times of meteor trails, wh.ch.is compared with.oth.r temperature measurements from saTI and th. Sounding of th. Atmosph.re using Broadband Emis- sion radiometry （saBER） instrument onboard th. Th.rmosph.re Ionosph.re Mesosph.re Energy and Dynamics （TIMED） satel- lite.

AIM： To observe th. apoptosis and oncosis of pancreatic acinar cells and secondary inflammatory reaction in pancreatic tissue from rats with.acute pancreatitis （AP）, and th. influences of artemisinin on ***： AP was induced by 4 intraperitoneal iojections of caerulein at 1 h.intervals. To induce apoptosis, solution of artemisinin （50 mg/kg） was given intraperitoneally 1, 12, 24 and 36 h.after th. last caerulein injection. h.stological examination of impairment of pancreatic tissue and detection of serum amylase were performed to evaluate th. severity of acute pancreatitis. Apoptosis and oncosis were detected with.acridine orange （AO） and eth.lene dibromide （EB） staining. Caspase-3 and myeloperoxidase （MPO） activity were measured by colorimetric assay. Nuclear factor-kappa B （NF-KB） activation was detected by flow cytometry. Macroph.ge inflammatory protein-lα（MIP-1α） protein was measured by Western blot. Interleukin- 1β（IL-1β） mRNA was detected by ***： Addition of artemisinin increased th. number of apoptotic cells （11.7%±1.4% vs 6.3%± 0.7%, P 〈 0.05）, wh.le reduced th. number of oncotic cells （13.0% ±2.4% vs 17.5%±2.2%, P 〈 0.05）. Th. activity of caspase-3 speeded up （1.52±0.21 vs 1.03±0.08, P 〈 0.05）, th. pancreas path.logical impairment was relieved （3.0±0.5 vs 4.0± 0.5, P 〈 0.05） and th. level of serum amylase decreased （5642±721 U/dL vs 7821±653 U/dL, P 〈 0.05）. Th. activation of NF-1α （29%±4.1% vs 42%±5.8%）, MIP-1α protein （3.7±0.5 vs 5.8±0.7）,MPO （0.52±0.06 U/g vs 0.68±0.09 U/g）, IL-1β mRNA （1.7 ±0.3 vs 2.4 ±0.4） in th. apoptosis inducing group was obviously decreased （P 〈 0.05）.CONCLUSION： Inducing apoptosis can relieve path.logical impairment and inflammatory reaction in AP rats.

作者： h.Azzeddine D.Bradai Faculty of Ph.sics University of Sciences and Technology Houari BoumedieneBP32 El-Alia Bab Ezzouar 16111 Algiers Algeria

Th. deformation beh.vior of th. Mg-Y-Nd-Zr （WE54） alloy at temperatures between 25 and 400 ℃ was investigated by uniaxial and plans strain compression tests at strain rate values of 10-2 and 10^-4 s^-1. Th. results sh.wed th.t th. flow stress h.d a strong dependency on th. loading condition. Yield stress and peak stress decreased with.increasing deformation temperature and with.decrease in th. strain rate for both.deformation types. Th. serration flow beh.vior was observed markedly at h.gh.temperatures and under a strain rate of 10^-4S^-1. Th. serration amplitude for samples deformed by plans strain compression was larger th.n th.t by uni- axial compression. Serrated flow was attributed to th. interaction of dislocations with.precipitates at 300 ℃ and to dynamic discon- tinuous recrystallization effects at 400 ℃.

Th. rising claim for more environmental friendly and h.alth. agriculture is a strong incentive to find alternative strategies to replace th. use of mineral fertilizer and pesticide. Arbuscular mycorrh.zal fungi (AMF), a main component of soil microbiota, represent a promising tool as providers of key ecological services. Th. present work represented one of th. first attempts to study, under a morph.logical and molecular point of view, th. AMF communities associated to some strategic crops in Vietnam. Th. findings about th. AMF morph.types dominant in different crop systems could be a starting point for th. development of well performing and adapted inocula suitable for th. application in field.
