UNLABELLEDOBJECTIVE; To observe clinical therapeutic effect and the mechanism of drug-separated moxibustion at the navel for delaying aging.

METHODSSeventy-one cases were randomly divided into 3 groups. The group of drug-separated moxibustion at the navel (n=30) were treated with drug-separated moxibustion at the navel, twice each week; the acupuncture group (n=21) with acupuncture at Shenshu (BL 23) and Taixi (KI 3) as main points once each day; the western medicine group (n=20) with oral administration of vitamin E capsules, 0. 1 g each time, twice daily. Their clinical therapeutic effects, and changes of cumulative scores, serum SOD activities and MDA contents after treatment were compared among the 3 groups.

RESULTSAfter treatment, clinical symptoms in the 3 groups very significantly improved (P < 0.01), with the group of drug-separated moxibustion at the navel more significantly improved (P < 0.01); in the 3 groups, SOD activities significantly increased (P < 0.01) and serum MDA contents significantly decreased (P < 0.01), and SOD activity and MDA content in the group of drug-separated moxibustion at the navel were not significantly different from those in the acupuncture group (P > 0.05), but significantly different from those in the western medicine group (P < 0.05).

CONCLUSIONThe drug-separated moxibustion at the navel can significantly delay aging.

UNLABELLEDOBJECTIVE To compare anti-oxidative effects of acupuncture at different Shichen (traditional twelve two-hour periods) accordin-17:00), You (17:00-19:00), Xu (19:00-21:00), Hui (21:00-23:00) periods according to the eight methods of the intelligent turtle, once each day, for 7 consecutive days. Changes of malondialdehyde (MDA) content and superoxide dismutase (SOD) activity after treatment were observed.

RESULTSSOD activities and MDA contents at the 12 periods were different in the healthy guinea pigs, SOD activity at Wu period was the highest and the lowest at Zi period; MDA content was the highest at Zi period and the lowest at Wu period. The needling method according to eight methods of the intelligent turtle could increase SOD activity in the guinea pigs. The increasing amplitude of SOD activity was the largest at Mao period and the smallest at the Wu period; it also could decreased MDA content, the decreasing amplitude of MDA was the largest at Wu period and the smallest at Hai period.

CONCLUSIONAcupuncture at different periods according to eight methods of intelligent turtle has different effects on serum SOD and MDA, which can increase SOD activity and decrease MDA content in the healthy guinea pig.

OBJECTIVETo explore the level and effect factors of superoxide dismutase (SOD) and malondialchelyche (MDA) of the people aged 90 years old and above in longevity regions in China.

METHODSFrom Xiayi county (Henan province), Zhongxiang county (Hubei province), Mayang county (Hunan province), Foshan county Sanshui district (Guangdong province) and Yongfu county (Guangxi province), the people of hundred-year were selected and numbered. The old people aged 90 - 99 according to the age and sex were appointed by the centenarians' code and 496 people were selected in total. Questionnaire investigation was conducted on nationality, education, nutrition, smoking, alcohol drinking, tea drinking and physical activities.436 blood sampling (4 ml Per sampling) were conducted and the level of triglyceride (TG), SOD, MDA, Ca, Mg, and some microelements were determined. Non-conditional logistic regression analysis was conducted to explore the effect factors of SOD and MDA in plasma.

RESULTSAnalysis showed that the activity of plasma SOD was (31.19 +/- 5.51) U/ml, and the content of MDA was (4.68 +/- 1.98) micromol/L. The SOD level of minority people of 90 years old and over was (27.55 +/- 4.97) U/ml, lower than that of Han nationality ((31.73 +/- 5.39) U/ml; t = 5.85, P < 0.01); the MDA level of minority people of 90 years old and over was (5.58 +/- 1.95) micromol/L, higher than that of Han nationality ((4.54 +/- 1.95) micromol/L; t = -3.94, P < 0.01). logistic regression showed, comparing with the Han nationality, the minority had lower level of SOD (OR = 0.493), and higher level of MDA (OR = 5.412, P < 0.05). Beside nationality, the factors significantly affecting the activity of SOD included the intake frequency of meat, intake frequency of eggs and plasma concentration of Se (OR values were 0.388, 2.260 and 1.906, P < 0.05). The factors significantly affecting the level of MDA included the intake frequency of milk, physical activity and the level of TG (OR values were 0.435, 1.850 and 1.647, P < 0.05).

CONCLUSIONThe level of SOD of the oldest-old people aged 90 years old and over is relatively higher than the younger ones, and the level of MDA is relatively lower in longevity region, China. The effect factors of SOD are nationality, meat intake frequency, eggs intake frequency and the level of Se in plasma. The effect factors of MDA are nationality, milk intake frequency, physical activity and the level of TG in plasma.

BACKGROUND/OBJECTIVES: Successful recovery of an animal from exercise is essential, especially prior to the next exercise session. This study was conducted to find an effective exercise-to-rest period ratio for the restoration of energy sources and replenishment of anti-oxidative status in tissue after exercise. MATERIALS/METHODS: Thirty-two rats were assigned to either non-training or training exercise groups for 5 weeks. After that period, the two groups were subdivided into four smaller groups: non-exercise (NE), exercise 0.5 hour and rest 1 hour (ER0.5:1), exercise 1 hour and rest 1 hour (ER1:1), exercise 2 hours and rest 1 hour (ER2:1). RESULTS: In the training group animals and compared to the NE group, the levels of plasma glucose after the rest period were significantly high in all ER groups but highest in the ER2:1 group. Similarly, the liver glycogen level was highest in the ER2:1 group. The plasma FFA level reached the highest level in the ER2:1 group but was similarly high in the ER0.5:1 group. Liver TG level was unchanged in the ER2:1 and ER1:1 groups but was significantly high in the ER0.5:1 group. Muscle TG levels were decreased in all three ER groups. Plasma protein levels were significantly high in the ER2:1 and ER0.5:1 groups. In both training animal and non-training animals, the liver protein levels did not change significantly between the NE and ER groups, irrespective of the exercise-to-rest ratio. In the training animal group, muscle protein level was significantly low in the ER2:1 and ER0.5:1 groups. The activity levels of superoxide dismutase and catalase, as well as the malondialdehyde concentration, were not significantly different between NE and ER groups, irrespective of the exercise-to-rest period ratio. CONCLUSIONS: These results indicate that animals provided with a 0.5:1 to 1:1 exercise-to-rest period ratio can restore their muscle energy sources and recover their anti-oxidative defense system.
