산소와 질소의 단순 화합물질인 산화질소 (nitric oxide) 는 생체내의 다양한 작용을 야기하는 시그날 물질로 주목을 받고 있으며 이의 작용에 대한 연구가 광범위하게 진행되고 있다. 본 논문을 통하여 저자는 수정란 대사에 미치는 산화질소 작용규명이 지금까지 어떻게 진행되어 왔는지 소개하였으며 본 물질에 대한 최근 연구결과를 설명하였다. 일련의 실험결과 산화질소는 수정란의 초기발생 저해인자로 작용하며 수정란 배양 중의 산화질소작용 억제에 의하여 배반포 발생이 현저히 증가한다는 사실을 밝혀냈다. 참고로 본 논문내용은 Mol. Reprod. Dev. (1998), Theriogenology (1999) 및 Fertil. Steril. (in press)에 개재된 연구결과를 요약한 것이다.

Porous alumina specimens with 80~92% relative densities were prepared from ultrasonic spray pyrolyzed alumina Powders by sintering at $1600^{\circ}$~ $1700^{\circ}C$. The exaggerated grain growth appeared to high sintering temperature and long soaking time. The microstructural development during sintering was investigated using image analysis. In the study of grain growth kinetics for sintering for spray prolyzed alumina powder, the activation energy for normal grain growth was 386.77 kJ/mol.

This study investigated changes in the catechin and alkaloid contents of Bosung green tea during different manufacturing processes and storage periods, using HPLC and UV-VIS spectrophotometer analysis. For changes in the catechin and alkaloid contents by roasting technique, we found that EGCG, CG and GCG decreased just slightly by processes performed before roasting, rather than after roasting. In addition, theobromine, caffeine, and ECG changed minimally throughout all the processes. For changes in the catechin and purine alkaloid contents of the green tea leaves during storage, EGCG, ECG, and CAF decreased considerably in the green tea stored at temperatures of $5^{\circ}C$ and $25^{\circ}C$, and they decreased by $20{\sim}30%$ after storage for 1 year. However, a quantitative difference was hardly observed in the catechin and alkaloid contents regardless of storage temperature.

Objective : The purpose of this study was to analyze the trend of clinical research on 'mild and sub-clinical depressions' in China. Method : The journal search was performed using China National Knowledge Infrastructure(CNKI). Our inclusion criteria were as follows: TCM clinical trials for mild, sub-clinical, early stage of depression. Exclusion criteria were the following: non-TCM clinical trials, disease-associated depression related clinical trials. Results : We included 16 papers in this study. 1. In this study, we realized there have been several mild and sub-clinical depressions related clinical trials conducted in the field of TCM. 2. The result of 10 Journals used the Hamilton Depression Rating Scale for diagnosis and assessment criteria of mild and sub-clinical depressions. 3. The selected journals categorized by various interventions, such as, herbal medicine(7), acupuncture(4), miscellaneous(5). 4. Also, 7 Journals showed the significant improvements in patients with mild and sub-clinical depressions by TCM interventions, and 5 studies of TCM patent prescription reported that herbal medicine therapy has less side effect than the western medicine. Conclusion : Through this study, we found out that several researchers in China performed clinical trials on mild and sub-clinical depressions constantly. From the result of this study, we need to concern about the necessity of research on the mild and sub-clinical depression in Korea. Therefore, this result could be used as a meaningful reference for the design of future clinical trials.

Objective: The purpose of this research is to investigate Chinese clinical studies of the treatment of hiccup after stroke with herbal medicine. Methods: We used the China National Knowledge Infrastructure (CNKI) database to search for clinical studies about using herbal medicine to treat hiccup after stroke. Results: Nineteen clinical articles Until August 31, 2017 were analyzed. The most commonly used herbal prescription was Xuanfudaizhe-tang (旋覆代?湯). According to analysis, the most commonly used medical herbs were Haematitum (代?石), Inulae Flos (旋覆花), and Pinelliae Tuber (半夏). Clinical symptoms, total incidence rate of adverse reaction, recurrence rate, symptom improvement time, patient satisfaction comparison, and dietary status improvement were used to evaluate the treatments. The effective rate of the treatment group was 86.0-97.8%, significantly higher than control group in all papers. Side effects occurred much less frequently in the treatment group than in the western medicine control group. Conclusion: The treatment of hiccup after stroke with herbal medicine was shown to be highly effective in 19 studies. Additional well-designed clinical trials are needed; this study can be used as a basis for further research regarding the treatment of hiccup after stroke.

Objective : We conducted this study to analyze some of the trends of treatments from the recent Chinese medical journals and contribute them to the oriental medical experiments and clinical research for the future. Methods : By referring to the Chinese medical journals that were published in China from 1999 to March, 2002, we analyzed the effective rates on frequency, methods, medical treatment, and diseases. Result : The average effective rate was 90.93%, which was very high. Lately, there have been no big changes in the methods of treatment. The methods of coordinating stomach-Qi, supplying Yin element, replenishing bone marrow, tonifying essence of life, and removing blood stasis are used by means of reinforcing Qi, producing blood, tonilying spleen, and replenishing the kidney. Conclusions : The decreased in bone marrow and leucopenia, and the side effects of radiotherapy and chemotherapy were more effectively treated when we used Korean oriental medical treatments. In addition, more Korean oriental medical experiments and clinical studies are needed in Korea, in the future.

Objectives : This study was performed to investigate the research trends of hypertension in Traditional Chinese Medicine(TCM), and it aims to promote hypertension research in Korean Medicine. Methods : We first collected more than 1,900 papers about hypertension research, and finally selected 108 papers related to this study. They were analyzed by the annul situation, the subject of the study, the perspective of TCM, the study stream, the research fields, the diagnostic patterns, and the distinguishing treatments of TCM. Results : The first review about hypertension in TCM was performed in 1963, and the number of studies has increased since 2000s. Doctors and researchers in China tried various diagnostic patterns to treat the patient because the diagnostic patterns were not unified. For this reason, most researches were reported to the diagnostic patterns and the treatments. Also we have discovered the diversity in treatments methods such as not only the typical herbal medicine, acupuncture, and Qigong but also specific treatments like Chuna, herbal acupoints stimulation, footbath, and pillow. Conclusions : Based on the results of this study, it can be proposed as follows : First, the various approach about hypertension in Korean Medicine is required. Second, the domestic research is needed to be extended to the external treatments as the distinguishing treatments of TCM.

Objectives: This research aimed to investigate Chinese clinical studies on the treatment of central post-stroke pain (CPSP) and thalamic syndrome after stroke with traditional herbal medicine (THM). Methods: Randomized controlled trials verifying the effects of herbal medicine on treating CPSP and thalamic syndrome after stroke were included in the study. Electrical and hand search were conducted in the China National Knowledge Infrastructure (CNKI), National Discovery for Science Leaders (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (Oasis) for CPSP and thalamic syndrome after stroke. A literature search was performed in the Chinese and Korean databases for papers published from January 1, 2010 to October 1, 2018. The selected literature was assessed by Cochrane's risk of bias. Results: Twelve reports on randomized controlled trials met the inclusion criteria from the 227 identified reports. Effective rate, comparison of visual analogy scale, present pain intensity, pain grading index, recurrence rate, follow-up, and a 36-item short form survey instrument were used to evaluate the treatments. The effective rate of the treatment group was significantly higher than that of the control group in all papers. Side effects occurred less frequently in the treatment group than in the western medicine control group. Conclusions: The treatment of CPSP and thalamic syndrome after stroke with THM was shown to be highly effective. Additional well-designed clinical trials are needed. This study can be used as a basis for further research on the treatment of CPSP and thalamic syndrome after stroke.
