  • This study conducts electrical stimulation to male white rat of Spargue-Dawley which is 7 weeks, has the weight of 240 g and is seemingly healthy for one or two weeks by means of neuromuscular electrical stimulator in order to examine the effects of neuromuscular electrical stimulation on its gastrocnemius, measures change of weight of gastrocnemius, serum and enzyme activity and then obtains the following conclusions. There is little difference in AST and CPK of weight and serum of gastrocnemius after one or two weeks of conducting neuromuscular electrical stimulation in all experimental groups. On the one hand, as a result of histochemical observation, NMES I group showed hypertrophy of perimysium and increase of sectional diameter of muscle fiber compared to comparison group, but NMES II group showed a similar result to comparison group. When ultrasubstructure was observed under electron microscope, I-type muscle fiber of NMES I group showed well-arranged mitochondria and it was similar to comparison group. II-type muscle fiber showed a large quantity of glycogen granules within sarcoplasmatic and the extension of luminal of T-tubule. I-type muscle fiber of NMES II group had small mitochondria and showed the vacuolar degeneration of mitochondria and extended T-tubule. II-type muscle fiber showed the extension of agranule cytoplasma reticulum with T-tubule and the reduction of amount of glycogen granule within partial sarcoplasmatic.

  • This study was to evaluate the single dose toxicity of Arecae Semen (AS) in male and female ICR mice. Aqueous extracts of AS (Yield = 13.15%) were administered as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy; organ weight and histopathology of 12 principle organs were examined. We could not find any mortality, clinical signs, and changes in the body and organ weight except for diarrhea. Diarrhea were observed in all three different dosage groups of male mice, and in 2000 mg/kg groups of female mice within 48hrs after administration. In addition, no AS extract related abnormal gross findings and changes in histopathology of principle organs were detected except for some sporadic accidental findings. Although the 50% lethal dose and approximate lethal dose of AS aqueous extracts in female and male mice were detected as over 2,000 mg/kg - the limited highest dosage recommended by KFDA guidelines. It should be carefully used in clinics because AS may be induced severe digestive tract disorders.

  • Intravenous and oral acute toxicity tests in ICR mice and SD rats and percutaneous acute toxicity tests in SD rats and NZW rabbits were conducted to evaluate the toxicity of DA-5018 and DA-5018 cream, respectively Clinical signs observed in mice and rats after the administration of DA-5018 were similar regardless of administration route. The observed clinical signs were jumping, wild running, lacrimation, ataxia, reddening of extremities and ears, ventral or lateral recumbency, respiratory distress, cyanosis, convulsion and death. Pulmonary enlargement and hemorrhage were observed in the animals died immediately after the dosing of DA-5018. At terminal necropsy, pulmonary enlargement and hemorrhage, corneal opacity and focal scabbing and depilation around nose were seen. LD$_{50}$ Values of DA-5018 are 11.5 mg/kg (mice, male), 12.6 mg/kg (mice, female), 88.3 mg/kg (rat, male) and 73.2 mg/kg (rat, female) in oral toxicity tests and 11.0 mg/kg (mice, male), 18.7 mg/kg (mice, female), 0.12 mg/kg (rat, male) and 0.32 mg/kg (rat, female) in i.v. toxicity tests. In the percutaneous acute toxicity tests of DA-5018 cream, no deaths occured in all the tested groups during 14-day observation period. There were also no abnormalities in the general conditions, body weight changes and on necropsy findings in all groups. LD$_{50}$ values of 0.1 ~0.9% DA-5018 creams in male and female rats and rabbits are >2000 mg/kg./kg.

Methods : Oriental medicine and Buddhism both make much use of respiration techniques. According to a comparative study on these; A group for the clinical application of oriental medical respiration methods, and A study both the differences and common features of oriental medical and Buddhist respiration techniques, to deliver therapeutic and preventive medical assistance to patients. Results and Conclusion : 1. Oriental medical respiration techniques have as their object the prevention and treatment of disease through smooth circulation of Gi(氣) and Hyeol(血) according to the concentration of the mind on acupuncture points. 2. Buddhist respiration techniques make use of planned psychological rest and ascetic practical expedience according to the close observation of the five senses(五感) of the real world through exhalation(呼) and inhalation(吸) based on Buddhist philosophy. 3. Although the pursuit of oriental medicine and Buddhism can be different, I think a need to develop new respiration techniques can lead to psychological balance and medical treatment through compounding both sets of knowledge.

  • This study was conducted to obtain acute information of the oral dose toxicity of lyophilized water extract of Pinelliae Rhizoma, a dried tuber of Pinellia ternata (PR) in male and female mice. In order to calculated 50% lethal dose (LD$_{50}$) and approximate lethal dose (ALD), test material was once orally administered to male and female ICR mice at dose levels of 2000, 1000, 500, 250, 125 and 0 (vehicle control) ml/kg (body weight). The mortality and changes in body weight, clinical signs, gross observation, organ weight and histopathology of principle organs were monitored 14 days after treatment with PR extract. We could not find any mortalities, clinical signs, changes in the body and organ weights, gross and histopathological findings except for dose-dependent increases in the hepatic fatty change frequencies detected in PR extract 2000 and 1000mg/kg treated in both male and female mice. The results obtained in this study suggest that LD$_{50}$ and approximate LD in mice after single oral dose of PR extracts were considered over 2000 mg/kg in both and female male mice, but more than 1000mg/kg of PR extracts treatment could induce slight hepatotoxicity the fatty changes in mice.

  • Purpose: This study was to identify the current issues and challenges of the nursing education program in Cambodia and to suggest recommendations to improve it. Methods: The World Health Organization Global Standards for the Initial Education of Nurses and Midwives were used as the analytic framework. Data were collected through a critical, constructive analysis of the literature, as well as observation with stakeholders in the area. Results: Cambodia experienced a shortage of nurses based on the demands of nurses. Moreover, the lack of institutional capacity, out dated and rudimentary nursing curriculum, under qualified nursing faculty, overcrowded classrooms, and lack of fundamental education materials and equipment for nursing education hampered the maintenance and improvement of the quality of pre-service nursing education in Cambodia. Conclusion: Strengthening the nursing educational resources and infrastructures, along with proper retention and enhancement of the faculty's capacity, clinical mentorship, and sustainable management of the nursing curriculum were recommended. Integrating the nursing theory and process into clinical practice and using strategic partnerships, would improve the quality and quantity of nursing education in Cambodia. There needs to be a synergistic relationship between nursing education and training relevant to the nursing care to meet the needs of the Cambodian population.

  • The present study was carried out to investigate the potential acute toxicity of bamboo leaf water extract by a single oral dose in Sprague-Dawley rats. Twenty male and female rats aged 5 weeks were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, 1250, 2500, or 5000 mg/kg body weight. Mortalities, clinical findings, and body weight changes were monitored for the l4-day period following the administration. At the end of 14-day observation period, all animals were sacrificed and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects on clinical signs, body weight, and gross finding at any dose tested. The results showed that the single oral administration of bamboo leaf water extract did not induce any toxic effect at a dose level of below 5000 mg/kg in rats and that the minimal lethal dose were considered to be over 5000 mg/kg body weight for both sexes.
