Heart rate recovery (HRR) is simply an indicator of autonomic balance and is a useful physiological indicator to predict cardiovascular morbidity and mortality. The purpose of this study was to compare the differences in HRR between metabolically healthy obesity group and metabolically unhealthy obesity and to ascertain whether heart rate recovery is a predictor of metabolic syndrome. Metabolic syndrome was defined according to the standards of the National Cholesterol Education Program Adult Care Panel III. Obesity was assessed according to WHO Asian criteria. It was classified into three groups of metabolically healthy non-obesity group (MHNO, n=113), metabolically healthy obesity group (MHO, n=66), metabolically unhealthy obesity (MUO, n=18). Exercise test was performed with Bruce protocol using a treadmill instrument. There was no difference in HRR between MHO and MUO ($32.71{\pm}12.25$ vs $25.53{\pm}8.13$), but there was late HRR in MUO than MHNO ($25.53{\pm}8.13$ vs $34.51{\pm}11.80$). HRR in obese was significantly correlated with BMI (r=-0.342, P=0.004), waist circumference (r=-0.246, P=0.043), triglyceride (r=-0.350, P=0.003), HbA1c (r=-0.315, P=0.009), insulin (r=-0.290, P=0.017) and uric acid (r=-0.303, P=0.012). HRR showed a lower prevalence of abdominal obesity, hypertriglyceridemia, and low HDL-cholesterol in the third tertile than in the first tertile. In conclusion, MHO had no difference in vagal activity compared with MHNO, but MUO had low vagal activity. HRR is associated with metabolic parameters and is a useful predictor of abdominal obesity, hypertriglyceridemia, and low HDL-cholesterolemia.

The purpose of this study is to analyze the nutrition composition and physiological changes, and to evaluate the food quality of live fish in cultured and wild fishes which have been kept in an aquarium tank. The moisture and lipid content of wild and cultured fishes when kept in an aquarium tank for seven-days storage was found to be lower than those of the initial stage storage(zero day). The breaking strength was also rapidly decreased in all of live fishes tested in this study as the periods of storage extended. The protein content did not differ significantly. However, the content of cortisol, which is a indicator indicating a stress reaction in tissues, was apt to increasing as the periods of storage extended. The cortisol content of wild fishes were higher than those of cultured fishes. On the other hand, the activity of activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), which is also a indicator indicating a stress reaction, were not changed in the serum of wild and cultured fish, suggesting the ALT and AST activity dose not directly related with a healthy loss originated from stress. The death ratio of wild fishes were higher than cultured ones due to limited activity and stress during the storage in a aquarium tank.

Abiotic stress is one of the most serious problems in plant productivity because it dramatically delays plant growth and development. One of the abiotic stresses, soil salinity, has an adverse effect on plant growth, particularly in areas where irrigation is necessary like semiarid Asia and Africa. Among several physiological parameters, anthocyanin accumulation is a valuable indicator of the condition of the plant, and it tends to increase under salt stress conditions because of its protective role in such an environment. Consequently, it may be important to search for well adapted genotypes for upcoming climate changes. Anthocyanins are known to have important roles in defense against biotic and abiotic stresses, providing important functions for protecting plant cells from reactive oxygen species. In this study, we investigated the anthocyanin accumulation between two Korean sorghum genotypes, Sodamchal and Nampungchal. The two genotypes were subjected to a regulated salinity condition, and the anthocyanin contents were evaluated in both. In Nampungchal, the anthocyanin content increased with 150 mM NaCl treatment during the time course of the experiment. However, the anthocyanin content of Sodamchal decreased in the same condition. The measured values of the anthocyanin content should be useful to identify the intensity of the salt tolerance in Sorghum bicolor L. Furthermore, we studied gene expression profiling of salt stress related genes with qRT-PCR. These results suggest that Nampungchal is a more tolerant genotype to salt stress compared to Sodamchal. This information should be useful for breeding salt-resistant cultivars in sorghum.

It has been reported that tight sportswear could have complicated influence on physiological function of human body. The purpose of this present study was to investigate the effect of wearing gradient compression tights (GCT) on muscle strength and EMG activity during repeated isokinetic muscle contractions. Four healthy male undergraduate students performed maximal voluntary isokinetic concentric muscle contractions on biomechanical test and training systems with GCT and loose pants as control (Cont) respectively. During each test, the peak torque of extensor and flexor contractions and the surface electromyography (sEMG) of the rectus femoris and medial gastrocnemius was recorded simultaneously, the peak torque was recorded as an indicator of muscle strength, and the average amplitude and mean power frequency of sEMG were calculated as indicators of EMG activity. The results showed that: the peak torque decreased gradually during continuous muscle contractions both when the Cont and GCT were worn, average sEMG and mean power frequency declined along with the repetitions of muscle contractions for both wearing conditions, and the change tendency was consistence with that of peak torque. There was no obvious difference between the peak torque recorded wearing the Cont or wearing GCT, but when GCT were worn, average sEMG was lower and mean power frequency was higher than the Cont condition. In 24 samples obtained from four subjects, 80% of results showed the same trend. So we could make a conclusion that wearing GCT had no obvious effect on the improvement of muscle strength, but it would affect the EMG activity positivly.

This study was performed to investigate the physiological responses of Oplopanax elatus by water condition. Drought stress was induced by withholding water for 26 days. The results show that $P_{N\;max}$, SPAD, gs, E and Ci were significantly decreased with decreasing of soil moisture contents. However, AQY and WUE were decreased slightly only at 26 day. This implies that photosynthetic rate is reduced due to an inability to regulate water and $CO_2$ exchange through the stomatal. According to JIP analysis, ${\Phi}_{PO}$, ${\Psi}_O$, ${\Phi}_{EO}$ and $PI_{ABS}$ were dramatically decreased at 21 day and 26 day, which reflects the relative reduction state of the photosystem II. On the other hand, the relative activities per reaction center such as ABS/RC, TRo/RC were significantly increased at 26 day. Particularly, Dio/RC and DIo/CS increased substantially under drought stress, indicating that excessive energy was consumed by heat dissipation. These results of chlorophyll a fluorescence show that the sensitivity changes photosystem II activity. Thus, according to the results, O. elatus was exhibited a strong reduction of photosynthetic activity to approximately 10% soil moisture contents, and JIP parameters could be useful indicator to monitor the physiological states of O. elatus under drought stress.

1. 배양액의 EC(mS/cm)와 배양액의 수분포텐셜은 직선적인 관계가 있고, EC의 증가는 배양액의 수분포텐셜 저하로 나타났으며 이에 따라 상위엽의 수분포텐셜이나 침투포텐셜이 변화하는 경향을 보였다. 2. 물리화학, 열역학적인 지표가 되는 수분포텐셜($\phi$w)은 배양액 뿐만 아니라 식물의 근, 경, 엽 및 과실에서의 수분 상태를 동일 단위로 나타내는 것으로 식물의 생장을 제어할 때 유일한 지표인 것으로 나타났다. 3. 배양액의 수분포텐셜 저하에 따라 상위엽의 수분포텐셜이나 침투포텐셜이 저하하는 경향을 보였다. 4. 배지내 Cu 농도가 5$\mu\textrm{m}$이상으로 되면 생육, 지상부의 생체중, 지하부의 건물중, 엽록소 함유율이 동시에 급격히 저하하는 경향을 보였다. 5. 배지내 Cu 농도의 증가에 따라서 생장율의 저하가 나타났으며 생장율의 저하에 따라 상위엽의 수분포텐셜이 저하하는 경향을 보였다. 팽압은 처리에 관계없이 거의 일정하게 나타나 팽압과 배지내 배양액의 Cu 농도 스트레스간에는 직접적으로 관계가 없는 것으로 나타났다. 수분포텐셜($\psi$w)은 식물신장, 세포신장을 수적으로 표현하는 것이 가능하다. 수원이 되는 용액이나 배지, 식물체를 동일 단위(㎫)로 관찰하는 것이 가능해 식물체의 수분생리적 비교 검사를 위한 유효한 방법으로 생각되었다.
