Acta Pharmaceutica Sinica 2004;39(11):869-875
AIMTo isolate polyphenols from grape seeds and to evaluate their antioxidant effects.
METHODSPure compounds were isolated by using Diaion HP20, Toyopearl HW40 chromatography repeatedly, as well as semi-preparative RP-HPLC, from ethyl acetate extract of grape seeds. IR, MS, NMR, CD, X-Ray crystal diffraction spectral analysis were used to identify the structures. The antioxidant effects of different type of structures were screened by reducing power and DPPH (alpha,alpha-diphenyl-beta-picrylhydrazyl) free radical scavenging tests. Then, SCGE (single cell gel-electrophoresis) technique was used to investigate the effects of these potent antioxidant phytochemicals on cellular DNA oxidative damage with mice spleen cells, damage was induced by H2O2.
RESULTSEleven compounds were obtained including 3 novel structures, viniferones A, B and C. Proanthocyanidin B4, catecin, epicatechin and gallic acid showed strong antioxidant power, and at lower concentration (10 micromol x L(-1), 25 micromol x L(-1)), they can prevent cellular DNA damage, while 150 micromol x L(-1) catechin induced damage by itself.
CONCLUSIONViniferones A, B and C were reported for the first time. That polyphenols investigated were shown to be good cellular DNA oxidative damage-preventing phytochemicals at lower concentration, could be used to explain the nutrient effect of grape seed polyphenols at certain degree. At the same time, higher concentration of polyphenols can induce oxidative damage, suggesting that dose is one factor to determine the nutrient effects.

OBJECTIVETo explore the diagnostic value of the radiologic characteristics of osteoporotic Kummell's disease.
METHODSTotal 16 patients with pathologically confirmed osteoporotic Kummell's diseases were reviewed from May 2010 to May 2012, including 4 males and 12 females with the mean age of 73.4 years (ranged, 67 to 83 years old). Radiologic imagings of all patients, including X-ray, CT and MRI, were analyzed retrospectively.
RESULTSIntravertebral linear clefts could be seen on the AP and lateral X-ray films of vertebrae. Sagittal and axial CT scans demonstrated the vacuum cleft phenomenon with liquid and air was identified within the vertebral body. Sagittal MRI showed the callapsed vertebral segment and the area of fluid signal with clear and intact border within the vertebral body. The fluid signal was low on T1-weighted images and high on T2-weighted images and stir images, which was corresponding to an intravertebral vacuum cleft.
CONCLUSIONThe radiologic characteristics of Kurmmell's diseases can provide valuable evidences for the early diagnosis.

To investigate the effect of treadmill running on the ability of learning in young rats, male Sprague-Dawley rats (5 weeks of age) were used for the experiment. Animals were randomly divided into the control and running groups (n=15 in each group). The rats in running group were made run on a motor-driven treadmill for 1 week at a speed of 2 m/min for the first 5 min, at a speed of 5 m/min for the next 5 min, then at a speed of 8 m/min for the last 20 min. Then the Morris water maze was used to observe learning and memory ability of rats in both groups. The tests consisted of place navigation and spatial probe test. We found that, in place navigation training, the latency of rats in running group was less than that in control group (P<0.05); and from the third training session on, there was significant difference between the rats in control and running groups in swimming velocity (P<0.01); furthermore, it was observed that the rats in running group had stronger motivation and more exact orientation in searching for platform, which could be indicated by the index of turn angle and angular velocity. In spatial probe test, there was no significant difference between the two groups in swimming velocity, percentage of swimming distance and frequency of crossing platform in D quadrant, where the platform situated (P>0.05). These findings suggest that low speed treadmill running can enhance the ability of learning in young rats.
