  • Although the effects of adenosine on the heart, including the clinical suppression of cardiac arrhythmias, have been recognized for more than half a century, it is only in the last decade that the therapeutic potential of adenosine has been recognized. The objective of this study was to determine if augmentation of myocardial adenosine levels during global ischemia improves functional recovery after reperfusion. We used to modified Langendonf system to evaluate myocardial protective effect. Isolated rat hearts were subjected to 90 minutes of deep hypothermic arrest(15$^{\circ}C$) with modified St. Thomas'Hospital cardioplegic solution used to provide myocardial protection. Myocardial adenosine levels were augmented during ischemia by providing exogenous adenosine in the cardioplegic solution. Two groups of hearts w re studied: (1) control group(n=10) cardioplegia alone; (2) adenosine group(n=10) adenosine(0.75mg/kg/min) added to the cardioplegic solution. Significantly better percent recovery(p<0.01) in hemodynamics(except heart rate) at 60 minutes after reperfusion was evident compared to baseline values in the adenosine group. (systolic no란ic pressure : 78.5$\pm$3.6% vs 66.6$\pm$5.9%, airtic overflow volume : 61.7$\pm$ 11.6% vs 37.2$\pm$ 15.4%, coronary flow volume 77.1$\pm$7.5% vs 57.2$\pm$ 11.1%, and cardiac output : 65.6$\pm$ 11.5% vs 44.2$\pm$ 12.4%). Heart rate was similar in two groups(94.4$\pm$4.8% vs 95.3 $\pm$ 6.8%). Adenosine groups resulted in significantly rapid recovery time of heart beat after reperEusion(p<0.01) (24.5$\pm$7.6 sec. vs 179.0$\pm$ 131.1sec.). In biochemical study, CPK levels(0.1 $\pm$0.3U/L vs 1.4$\pm$0.8U/L) and lactic acid levels(0.08$\pm$0.Immol/L vs 0.34$\pm$0.2 mmol/L) were significantly low in adenosine groups(p<0.01). We concluded that adenosine included cardioplegia have better recovery effects after r perfusion in myocardial ischemia compared to adenosine free cardioplegia.

  • This study was investigation for primary bionomical characteristics, emergence rate of wintering type pupa and oviposition preference, of Papilio xuthus. The emergence rate of wintering type pupa stored at cold chamber($4{\pm}1^{\circ}C$) was 85%, after 10 months. The average emergence rate of wintering type pupa during storage was 89.6%, and the emergence periods were $7.9{\pm}1.9days$ in room temperature. Mating ratio in large oviposition room, $6,000{\times}6,000{\times}3,500$ mm($W{\times}L{\times}H$), was $86.7{\pm}5.8%$ higher than $63.3{\pm}15.3%$ in small room, $2,500{\times}3,000{\times}2,000$ mm($W{\times}L{\times}H$). But the number of eggs in the large room were $137.0{\pm}16.5$ fewer than $141.7{\pm}20.4$ in the small room. As a result of oviposition preference experiment on three different host plants, 10 mated female laid $141.7{\pm}27.8$ on the leaves of Phellodendron amurensew more than $67.7{\pm}20.6$ on Zanthoxylum schinifolium and $77.0{\pm}21.8$ on Citrus unshiu. The egg periods were $4.4{\pm}0.8$ days after oviposition, and the hatchability was 92.2% in $25^{\circ}C$ room condition. The larval period were $19.9{\pm}2.1$ days in the high temperature, long day condition($25^{\circ}C$, 14L : 10D). The headwidth of each developmental larval stage were $0.72{\pm}0.02$(1st), $1.19{\pm}0.02$(2nd), $1.65{\pm}0.05$(3rd), $2.43{\pm}0.07$(4th), $3.21{\pm}0.12$(5th). The pupal ratio was 91.6%.

  • This study was conducted to investigate the effect of sodium intake on serum lipids and glucose. 20 young adult women were fed the diets containing 290.5 mEq (high-Na diet) and 51.3 mEq (low-Na diets) Na for 6 days, respectively. Serum lipids, glucose, and other parameters after high-Na diet and low-Na diet were compared. The results would be summarized as follows. The mean age, body weight, height, and blood pressure of the subjects were 22.9$\pm$2.5 years,54.7+6.6 kg, 160.0$\pm$4.8 cm, 110.3$\pm$7.7/67.5$\pm$19.7 mmHg, respectively. Body weight, BMI, and diastolic blood pressure were significantly higher at the end of high-Na diet than of low-Na diet (p<0.001 p<0.001, p<0.05). However, there were not significantly different in height and systolic blood pressure between high- and low-Na diet. Serum cholesterol, LDL-cholesterol, and HDL-cholesterol were not significantly different with Na intakes. Serum triglyceride was significantly higher at the end of high-Na diet than of low- Na diet (p<0.05) Serum apo A-I was significantly decreased in low-Na diet, while apo B was increased (p<0.001, p<0.001). Thrombin time and prothrombin time, blood aggregation time were significantly faster following low-Na diet (p<0.001, p<0.05). There was not significantly different in serum glucose between high- and low-Na diet. However, serum insulin was significantly higher following low-Na diet (p<0.01). It is concluded that diastolic blood pressure, serum triglyceride, serum apo A-I, blood aggregation time were decreased in low-Na diet, while serum apo B and serum insulin were increased. These results suggest that Na-restricted diet affects not only blood Pressure but other biochemical parameters in blood. Therefore, for the patients who need restricted Na diet, it would be suggested that various biochemical changes should be carefully considered along with dietary Na manipulation.

  • Purpose: The objective of this study was to examine the association of temperature-fluctuation with freshness quality in various foods. Methods: We investigated the effects of storage conditions on antioxidant activities of cherries and romaine lettuce during storage at $0.7{\pm}0.6^{\circ}C$, $1.2{\pm}1.4^{\circ}C$, and $1.6{\pm}2.8^{\circ}C$. Cherries and romaine lettuce were stored for a period of 9 days and 7 days, respectively. We also analyzed the effects of storage conditions on fresh quality of beef and salmon during storage at $-0.3{\pm}0.8^{\circ}C$, $-0.6{\pm}2.3^{\circ}C$, and $-1.5{\pm}4.4^{\circ}C$. Both of them were stored for a period of 14 days. Results: The amount of water loss was highest in beef, and the microbial count was also the highest at $-1.5{\pm}4.4^{\circ}C$. In the case of salmon, there was no difference in water loss according to storage, and TBA value was significantly increased at $-1.5{\pm}4.4^{\circ}C$. Moisture retention was the highest at $0.7{\pm}0.6^{\circ}C$ in both romaine lettuce and cherry samples. The contents of polyphenol and flavonoid were significantly higher in cherries, and content of polyphenols in romaine lettuce was significantly higher at $0.7{\pm}0.6^{\circ}C$ (p < 0.05). DPPH activity decreased in the order of $0.7{\pm}0.6^{\circ}C$ > $1.2{\pm}1.4^{\circ}C$ > $1.6{\pm}2.8^{\circ}C$ over 7 days. Conclusion: The results indicate that temperature-fluctuation may affect qualities of foods stored in a refrigerator.

  • This study was performed to investigate the effects of parity and season on the embryo production in superovulated Hanwoo cows. Superovulation was performed from 1 to 8 times by repeated superovulation treatment of Hanwoo cows (n = 22). Irrespective of estrous cycle, donor cows were received a CIDR, progesterone (50 mg) and estradiol benzoate (2.5 mg). After 4.5 days, the donor cows were superovulated with total 28AU FSH (Antorin R-10) administrated twice daily in a decreasing dose for 4 days. On $6^{th}$ and $7^{th}$ of FSH injection, 2.5 mg and 15 mg $PGF_2{\alpha}$ were injected i.m, respectively. CIDR was removed at the $7^{th}$ FSH injection. The donor cows received $200{\mu}g$GnRH at 48 hrs after $1^{st}$ $PGF_2{\alpha}$ injection. The donor cows were artificially inseminated three times after estrous detection at 12 hr intervals and embryos were recovered 7 days after estrous detection. The mean number of total ova, transferrable embryos, degenerated embryos and unfertilized oocytes were $11.6{\pm}7.9$, $5.5{\pm}4.4$, $3.0{\pm}3.3$ and $2.6{\pm}4.1$ per donor cows, respectively. A higher number of total ova were recovered in parity 3~5 ($14.3{\pm}1.3$) than 1~2 ($8.9{\pm}1.9$, P<0.05). The number of recovered normal embryos is significantly higher in parity 3~5 ($7.3{\pm}0.8$) than that of over 6 ($3.7{\pm}1.5$). Significantly higher number of total ova and normal embryos were recovered in summer ($16.4{\pm}2.3$, $8.1{\pm}1.4$) than in autumn ($10.1{\pm}1.8$, $4.5{\pm}1.1$) and winter ($6.3{\pm}1.8$, $3.3{\pm}1.1$), respectively (P<0.05). Transferable embryos were significantly higher in summer ($7.6{\pm}1.3$) than in winter ($3.0{\pm}1.0$, P< 0.05). The results were showed that parity and season affecting on the production of embryos in superovulated Hanwoo.

  • Purpose: PTH (parathyroid hormone) level is a useful index for prediction of hypocalcemia after thyroidectomy. The fast results are required for an early diagnosis of hypocalcemia. In this study, we evaluated the PTH change according to incubation time, and investigated the usefulness of hypocalcemia diagnosis of PTH results in early incubation time. Materials and Methods: The subjects were 131 patients who had taken the PTH test from July to August in 2009. All experiments were used IRMA method. PTH value were evaluated with the correlation between precision (10 times repeat) and recovery rate and at 0.5, 3, 6 and $18{\pm}2$ (below overnight) hours following incubation time. Data analysis was investigated with relationship of the sensitivity, specificity, PPV (positive predictive value) and accuracy. Results: The correlation was time-dependent with levels reaching $R^2$=0.987 at 0.5 hours, $R^2$=0.993 at 3 hours and $R^2$=0.996 at 6 hours compare to overnight levels. The precision (%CV${\pm}$SD) were $15.92{\pm}15.54$ at 0.5 hours, $6.91{\pm}7.38$ at 3 hours, $4.30{\pm}4.69$ at 6 hours and $4.59{\pm}2.59$ at overnight. The recovery rate (%Mean${\pm}$SD) were $96.8{\pm}5.44$ at 0.5 hours, $102.6{\pm}4.35$ at 3 hours, $100.7{\pm}2.56$ at 6 hours and $102.2{\pm}5.98$ at overnight. When 15 pg/ml of overnight density was set up as criteria, we measured the sensitivity, specificity and PPV, accuracy at 0.5, 3, 6 hours. The sensitivity was shown to 97.5% at all times. The specificity was 96.0% at 0.5 hours, 100% at 3 hours and 92.3% at 6 hours for control, respectively. The PPV was 86.6% at 0.5 hours, 100% at 3 hours and 92.8% at 6 hours. The accuracy was shown to 84.7% at 0.5 hours, 97.5% at 3 hours and 90.6% at 6 hours. These data were accompanied by a corresponding PTH value of overnight incubation time, which significantly correlated with early time results. Conclusion: The values of PTH at 3 hours has favorable the rate of concordance of 94.1% and may be useful for prediction of hypocalcemia, and it responses to overnight incubation PTH values. Therefore, This method may be an attractive alternative to proper treatment to stop symptom revelation by giving a calcium agent to the patient.
