국내 수박(Citrullus lanatus) 품종의 발아율에 대한 Solid Matrix Priming(SMP)의 영향을 평가하였다. Micro cel-E가 SMP 처리에 가장 이상적인 matrix로 밝혀졌으며, 종자:matix:물의 비율은 10:5:10(w/w/w)로, 25°C 에서 3일 동안 처리했을 때 유근의 돌출없이 발아속도가 촉진되었다. SMP 처리 과정 동안 초기 4시간 동안의 수분 흡수율은 급격하게 증가했으며, 이후 72시간 동안은 더 느린 속도로 흡수되었고, 처리 마지막 시간까지 수분 흡수 율은 41%이었다. 발아 온도와 상관없이, SMP 처리된 종자는 발아 시간이 단축되면서 발아율이 향상되었다. 특히, 최적 발아 온도보다 낮은 온도에서 발아율이 높았다. 품종별 차이는 있었으나, 특히 ‘해찬꿀’과 ‘리코스위트’ 품종 에서 발아율이 유의미하게 증가하였다. 또한 일부 품종에서 SMP 처리 종자의 유묘출현율과 초장, 생체중이 무처 리에 비하여 증가한 값을 보였으며, SMP 처리로 종자의 발아속도 및 유묘활력을 증진시켜 우량 묘 확보가 가능한 것으로 판단되었다.

The purpose of this study was to compare acupuncture-like transcutaneous electrical nerve stimulation(ALTENS) with conventional transcutaneous electrical nerve stimulation(C-TENS) for crossover effect in healthy subjects. Forty subjects recieved ALTENS(20 persons), C-TENS(20 persons) to one upper extremity. Each technic was applied to the motor point of the wrist extensor muscle group for twenty-minutes. With the subject placed in supine the technics were applied at 80 Hz, 2-10 mA(ALTENS) and 10 Hz, 4-12 mA(C-TENS). Results revealed: (1) a significant difference between the pretreatment and posttreatment in each group(p<.05) (2) no significant difference between ALTENS and C-TENS(p>.05). In conclusion, there was no difference between ALTENS and C-TENS for crossover effect.

Background: Sanguisorba officinalis has been used in traditional Asian medicine owing to its beneficial effects on various diseases. The purpose of this study was to evaluate the effect of S. officinalis on the antioxidant system of Streptozotocin (STZ) and Alloxan (ALL) induced diabetic rats. Methods and Results: Triglyceride and Low-Density Lipoprotein (LDL)-cholesterol levels decreased in the STZ-induced diabetic groups treated with S. officinalis extract (SOE) compared to the corresponding levels in the control groups. Moreover, in the ALLinduced diabetic groups, SOE reduced triglyceride, LDL-cholesterol, and High-Density Lipoprotein (HDL)-cholesterol levels. Malondialdehyde (MDA) levels decreased significantly in the STZ and ALL-induced groups treated with SOE compared to the corresponding levels in the control group. Further, Glutathione (GSH) levels increased but did not reach statistical significance. The levels of Superoxide Dismutase (SOD) and Glutathione-S-Transferase (GST) showed a tendency to recover with SOE treatment in the STZ and ALL-induced diabetic groups. In addition, Catalase (CAT) levels in the SOE treatment group decreased significantly compared to those in the control group. Conclusions: These results suggest that SOE might be an effective agent in attenuating oxidative stress in diabetic patients by improving blood lipid profiles and inducing the anti-oxidative enzyme systems.
