To measure temperature in microwave heating condition by thermocouple or thermistor is limited. In order to overcome this problem kinetics of ascorbic acid destruction was introduced. Activation energy for destruction of ascorbic acid was obtained under conventional heating condition. Arrehnius equation was used for prediction of rate constant under microwave vacuum heating condition. Then prediction of temperature could be obtained by using kinetic of ascorbic acid destruction that is calulated by the predicted rate constant.

The toxicity of perilla-chinese Basil, Perilla frutescens whole plant-derived materials to third-instar of larva Plutella xylostella was examined using that of four insecticides and 5 constituents of P. frutescens from other research materials. The active principle of P. frutescens was identified as the sesquiterpenoids α-farnesene by spectroscopic analysis. In leaf-dipping bioassay, α-farnesene (LD50, 36.9) was 3.9 times more toxic than β-farnesene (LD50, 145.2) against P. xylostella larva, based on 48h LD50 values. This compound was less toxic than insecticides. Naturally occurring α-farnesene merit further study as potential diamond back moth control agent.

The expression of a chimeric transgene (nos-npt II) has been examined in 9 years old transgenic poplars (Populus koreana x P. nigra) growing in a nursery. The expression of the gene in twenty six independentely transformed plants were examined by 1) enzyme (NPT II) assay, 2) RT-PCR, and 3) resistance to kanamycin. High NPT II activities in young leaves of all the transformed plants were found even without a selection pressure for antibiotics for 9 years. However, the activity varied with the positions of leaves in the stem in that young leaves showed higher activity than did mature tissues. When leaf segments were cultured in the presence of 150 mg/l kanamycin, only those from young leaves produced vigorously growing callus. However, as in the case of NPTII assay, the leaf segments from mature leaves did not form callus well on the media. RT-PCR with nptII specific primers also showed that amplification products were observed only when RNAs from young tissues were used. The total RNA gel showed that while RNA in young leaves are relatively stable and in a large quantity, those in old leaves were mostly degraded. All the above results suggest that the gene is transcriptionally active only in young tissue even though it is attached to a constituitive promoter. Therefore, the expression of foreign gene in poplar plants seemed to be affected by the metabolic state of the cells and thus vary greatly with the developmental stages and the age of tissue.

This study aims to understand some related types (to DiSC behavioral ones) through an analysis about DiSC behavioral types of freshmen at the clinical pathology department in the University. In order to do that, a total of 34 male and female students were surveyed. General characteristics and DiSC behavioral types for the targeted students were analyzed for frequency and percentage. For the frequency, the Chi-square test was performed and the level of significance was set to p<0.05. For the elements to select the university at general characteristics from the result of this study, 21 students were found to have selected the university voluntarily (61.8%). For the information about the clinical pathology department, 14 students were found to be informed through media (41.2%) and 7 students were informed through their parents (20.6%). For the DiSC behavioral types of the students majoring in clinical pathology, 18 students were found to be I type (53.0%), 8 students were C type (23.5%), 5 students were S type (14.7%) and 3 students were D type (8.8%). The relevance between general characteristics and DiSC behavioral type were found to be insignificant. As this study is aimed, there is no significant relevance between general characteristics and DiSC behavioral types, but through an understanding of characteristics of the students majoring in the clinical pathology, helping freshmen who are taking their first steps to adapt themselves to a new environment by diagnosing and understanding their behavioral types, understanding behavioral styles of those four types and guiding them in a positive direction, the method should be considered to raise their satisfaction about the major.

Objective: This study was carried out to compare changes in pain, swelling and range of motion (ROM) between the two groups according to physical therapy intervention. Design: Randomized controlled trial. Methods: There were a total of 20 elderly subjects ages 65-75 years old who have been admitted to the hospital for a total knee arthroplasty. After surgery, the experimental group (n=10) carried out quadriceps femoris muscle strengthening exercise, hamstring stretching exercises and gastrocnemius stretching exercise with a physical therapist for 30 minutes and additionally, received ice pack therapy for 20 minutes once a day. The control group (n=10) carried out continuous passive motion for 30 minutes and received ice pack therapy for 20 minutes once a day. The experimental group and control group carried out each intervention program for 2 weeks 3 times a week. The Visual Analogue Scale was used to assess pain, tape measurements were taken to assess swelling, and a steel goniometer was used to assess knee joint ROM. Results: As a result, the experimental group showed a statistically significant decrease in the pain and swelling, and a significant increase in knee flexion ROM after the intervention, compared to the control group (p<0.05). There was a significant improvement in pain, edema, and knee flexion and extension ROM in all subjects after intervention (p<0.05). Conclusions: According the results of this study, exercise in the experimental group is effect on the pain, swelling and ROM for total knee arthroplasty.

Platelets play an essential role in hemostasis through aggregation and adhesion to vascular injury sites but their unnecessary activation can often lead to thrombotic diseases. Upon exposure to physical or biochemical stimuli, remarkable platelet shape changes precede aggregation or adhesion. Platelets shape changes facilitate the formation and adhesion of platelet aggregates, but are readily reversible in contrast to the irrevocable characteristics of aggregation and adhesion. In this dynamic phenomenon, complex molecular signaling pathways and a host of diverse cytoskeleton proteins are involved. Platelet shape change is easily primed by diverse pro-thrombotic xenobiotics and stimuli, and its inhibition can modulate thrombosis, which can ultimately contribute to the development or prevention of thrombotic diseases. In this review, we discussed the current knowledge on the mechanisms of platelet shape change and also pathological implications and therapeutic opportunities for regulating the related cytoskeleton dynamics.

<P>Hepatitis C virus (HCV) has become a major public health issue. It is prevalent in most countries. HCV infection frequently begins without clinical symptoms, before progressing to persistent viremia, chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC) in the majority of patients (70% to 80%). Alcohol is an independent cofactor that accelerates the development of HCC in chronic hepatitis C patients. The purpose of the current study was to evaluate ethanol-induced hepatic changes in HCV core-Tg mice and mutant core Tg mice. Wild type (NTG), core wild-Tg mice (TG-K), mutant core 116-Tg mice (TG-116) and mutant core 99-Tg mice (TG-99) were used in this investigation. All groups were given drinking water with 10% ethanol and 5% sucrose for 13 weeks. To observe liver morphological changes, we performed histopathological and immunohistochemical examinations. Histopathologically, NTG, TG-K and TG-116 mice showed moderate centrilobular necrosis, while severe centrilobular necrosis and hepatocyte dissociation were observed in TG-99 mice with increasing lymphocyte infiltration and piecemeal necrosis. In all groups, a small amount of collagen fiber was found, principally in portal areas. None of the mice were found to have myofibroblasts based on immunohistochemical staining specific for α-SMA. CYP2E1-positive cells were clearly detected in the centrilobular area in all groups. In the TG-99 mice, we also observed cells positive for CK8/18, TGF-β1 and phosphorylated (p)-Smad2/3 and p21 around the necrotic hepatocytes in the centrilobular area (<I>p</I> < 0.01). Based on our data, alcohol intake induced piecemeal necrosis and hepatocyte dissociation in the TG-99 mice. These phenomena involved activation of the TGF-β1/p-Smad2/3/p21 signaling pathway in hepatocytes. Data from this study will be useful for elucidating the association between alcohol intake and HCV infection.</P>
