  • Experimental induction of polycystic ovary (PCO) resembling some aspects of human PCO syndrome was produced using the long-acting compound estradiol valerate (EV). Our previous study on the role of Korean red ginseng total saponins (GTS) in a steroid-induced PCO rat model demonstrated that electro-acupuncture modulates nerve growth factor (NGF) concentration in the ovaries. In fact, the involvement of a neurogenic component in the pathology of PCO-related ovarian dysfunction is preceded by an increase in sympathetic outflow to the ovaries. In the present study, we tested the hypothesis that therapeutic GTS administration modulates sympathetic nerve activity in rats with PCO. This was done by analyzing NGF protein and NGF mRNA expression involved in the pathophysiological process underlying steroid-induced PCO. EV injection resulted in significantly higher ovarian NGF mRNA expression in PCO rats compared to control rats, and PCO ovaries were counteracted by GTS administration with significantly lower expression of NGF mRNA compared to EV treated ovaries. However, NGF protein was unaffected in both EV and GTS treated ovaries compared to control rats. These results indicate that EV modulates the neurotrophic state of the ovaries, which may be a component of the pathological process by which EV induces cyst formation and anovulation in rodents.

  • In order to determine the effects of annexing bile extracts of bears on the anti-fibrotic effect of Injinhotang. Mix compound of Injinhotang and bile extracts of bears were administered to the carbon tetrachloride ($CCl_4$)-induced cirrhotic rats during 20 days and the changes of serum levels of GOT (glutamic-oxalacetic transaminase), GPT (glutamic pyruvic transaminase), LDH (lactate dehydrogenase), ALP (alanine phosphatase), GGT (gamma glutamyl transpeptidase) and T-BIL (total bilirubin) were monitored with comparison to the results of Injinhotang administered group. The results were summarized as follows. 1. A significant (p<0.01) increase of serum GOT levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. In addition, a significant (p<0.05) increase were also detected In Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 2. A significant (p<0.01) increase of serum GPT levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. Although significances were not recorded, increase of serum GPT levels were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 3. A significant (p<0.01) increase of serum LDH levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. Although significances were not recorded, increase of serum LDH levels were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 4. A significant (p<0.01 or p<0.05) increase of serum ALP levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. In addition, a significant (p<0.05) increase were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 5. A significant (p<0.01) increase of serum GGT levels were observed in control and Injinhotang-administered group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang with Fel Ursi-administered group. 6. A significant (p<0.01) increase of serum T-BIL levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. Although significances were not recorded, increase of serum T-BIL levels were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. In conclusion, it is considered that bile extract of bears has some additional effect to the anti-fibrotic effect of Injinhotang but to know the exact mechanism of suitable dose and duration of administration, further studies such as pharmacokinetics and dose-dependent pharmacological studies were needed

  • The objective of this study was to determine the effectiveness of topical 5% EMLA cream versus 20% Benzocaine gel in reducing pain from intra oral needle insertion alone as well as injection of anesthetic. The 2 topical anesthetics were tested against each other bilaterally using a randomized, controlled, single blinded, split mouth design. Phase I was conducted to find out the rapidity of onset action of the two agents on anterior/posterior vestibules and anterior/posterior palatal mucosa. Phase II was conducted to evaluate the efficacy of the two topical anaesthetic agents in reducing the pain of intraoral injections. The agents were left in anterior/posterior vestibules and anterior/posterior palatal mucosa for the amount of time recorded in phase I. Subjects recorded pain on a 100-mm modified visual analog scale(VAS). A pulse oximeter was used to recorded the preoperative and postoperative pulse rates. In phase I of the study, two topical agents showed the longer onset of action at anterior part and vestibules than posterior part and palatal mucosa. EMLA cream showed the rapidest onset of action compared to benzocaine gel except on anterior palatal mucosa. In phase II of the study, the VAS grading of the pain for anesthetic administration showed EMLA cream was significantly(P<.05) better in elimination or reducing the pain on the anterior/posterior palatal mucosa. In conclusion, EMLA cream showed the rapidest onset of action compared to benzocaine gel except on anterior palatal mucosa. EMLA cream was found to be superior to Benzocaine gel with regards to pain reduction for anesthetic administration especially on anterior and posterior palatal mucosa.

  • Metabolism and phamacokinetics of albendazole have been studied in Korean native cattle after oral administration of 5 mg/kg of albendazole. As ABZ is known to be rapidly biotransformed to many metabolites in most animal species, it is very imperative to establish the analytical conditions for its metabolites. LC/MS methods for ABZSO and ABZS $O_2$met every requirement enough to study the metabolism of pharmacokinetics of albendazole in Korean native cattle. The parent drug (ABZ) was only measured at first two time points of 0.5 h and 1h, whereas two metabolites were consistently formed between 0.5 h to 48-72 h post-treatment. Formation kinetics for ABZSO and ABZS $O_2$were similar. Time to peak concentration (Tmax) of ABZ-SO appeared at 12h post-treatment of ABZ, faster than that of ABZS $O_2$at 24h. Cmax of ABZS $O_2$(1.05$\pm$0.05 ug/ml) was 1.09 times higher than that of ABZSO (0.96$\pm$0.15). Elimination half-life of ABZS $O_2$(4.2 h) was much shorter than ABZS $O_2$(7.0h) (p<0.005). ABZSO was detected until 48h post-administration but ABZS $O_2$was measurable even at 72h post-dosing. AU $C_{0longrightarrow{\infty}}$ of ABZSO was smaller than that of ABZS $O_2$. Regimen of ABZ is advised to take into consideration is metabolite profiles, especially that of ABZSO, an active metabolite.

  • This study was designed to investigate whether Sasa borealis leaves extracts (SLE) may inhibit yeast ${\alpha}-glucosidase$ and ${\alpha}-amylase$ activities and postprandial hyperglycemia in STZ-induced diabetic mice. Freeze-dried SLE was extracted with 70% methanol and followed by a sequential fractionation with dicholoromethan, ethylacetate, butanol, and water. Both ethylacetate and butanol fractions showed high inhibitory activities against the ${\alpha}-glucosidase$ and ${\alpha}-amylase$ enzymes. The $IC_{50}$ of ethylacetate and butanol fractions against ${\alpha}-glucosidase$ were 0.54 and 0.63 mg/mL, respectively, indicating a greater inhibition effect than acarbose (0.68 mg/mL) (p<0.05). Likewise, the two fractions exhibited a smaller $IC_{50}$ against ${\alpha}-amylase$, compared with acarbose (p<0.05). However, the yield of ethylacetate fraction of SLE was relatively small. Postprandial blood glucose testing of normal mice and STZ-induced diabetic mice by starch soln. loading (2 g/kg B.W.) showed that postprandial blood glucose level at 30, 60, and 120 min were markedly decreased by single oral administration of SLE butanol fraction (200 mg/kg B.W.) in both normal (p<0.0l) and diabetic mice (p<0.0l). Furthermore, the incremental area under the curve (AUC) was significantly lowered via SLE administration (5,745 versus 12,435 $mg{\cdot}mim/dL$) in the diabetic mice (p<0.0l). The incremental AUC in normal mice corroborated the hypoglycemic effect of SLE (p<0.0l) found in the diabetic mice. These results suggest that SLE may delay carbohydrate digestion and thus glucose absorption. In addition, SLE may have the potential to prevent and treat diabetes via its ability on lowering postprandial hyperglycemia.

  • Type 2 diabetes mellitus (NIDDM) is a metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. In order to control the type 2 diabetes mellitus, anti-hyperglycemic effect of Triticum aestivum L. water extracts (TAWE) was investigated in 7 week old male diabetic C57BL6/J-ob/ob mice. For the experiments, the diabetic animal model ob/ob mice and non-diabetic animal model lean mice were divided into 3 groups: non-treatment control group (Control), and two experimental groups orally treated with 25 or 100 mg/kg/day dose of TAWE (TAWE-25 and TAWE-100, respectively). The lean mice were used as the non-diabetic normal control. TAWE was orally administrated for 6 weeks and the diabetic clinical markers, including blood glucose level, body weight, organs weight and insulin level were determined. The oral administration of TAWE-100 in ob/ob diabetic mice significantly decreased blood glucose level (78.4%) and body weight (11.9%) compared with diabetic control group. The weights of organs, including spleen, liver, kidneys, heart and lung were not different among groups, while the treatments of TAWE-100 in ob/ob diabetic mice significantly reduced blood total cholesterol (24.35%) and triglyceride (23.97%) levels compared with the diabetic control group. The levels of serum insulin and glucose tolerance were improved after TAWE-100 treatment in ob/ob diabetic mice. Moreover, the immunohistochemical staining for insulin detection in pancreatic islet $\beta$-cells expressed high level of insulin in TAWE-100 treated ob/ob mice. From the above results, the intake of TAWE may be effective in anti-hyperglycemia by the attenuation of glucose and lipid levels. TAWE-containing diets or drugs may be beneficial for controlling diabetes mellitus type 2 in human.

  • The aim of this study was to establish the appropriate guidelines in the sedation techniques and to organize the continuing education programs for the sedation in future under the direction of Committee on Sedation, Education and Research under the Korean Academy of Pediatric Dentistry(KAPD). The surveys on the sedation technique were performed on 111 organizations which practices the sedation and responded to the survey via online and e-mail by February 2014. The collected survey were analyzed. The purpose of sedation was mainly to manage the children's behavior and its uses were primarily on 3~4 years old children. The most frequent duration of treatment was 1~2 hours to treat both maxillary and mandible. The preferred dosages of sedative drugs were chloral hydrate(CH) 50~70 mg/kg, hydorxyzine(Hx) 1~2 mg/kg, and intramuscular midazolam(Mida IM) 0.1~0.2 mg/kg. The preferred combination of the sedative drugs were CH + Hx + $N_2O/O_2$(67.6%), CH + Hx + Mida submucosal administration (SM) + $N_2O/O_2$(29.7%), and Mida IM + $N_2O/O_2$(23.4%). The administration of additional sedatives was carried out at 48%, mainly using Midazolam. 87.5% of the respondents experienced the adverse effects of the sedation such as vomiting/retching, agitation during recovery, subclinical respiratory depression, staggering, and etc. Among them, only 20% periodically retrain the emergency management protocol. About the discharge criteria for patients after the sedation, the respondents either showed a lack of clear criteria or did not follow the recommended discharge criteria. 86% of the respondents expressed the interests in taking a course on the sedation and they wanted to learn mostly about the sedation-related emergency management, the safe dosage of the sedative drugs, and etc. The use of sedation in pediatric dentistry must be consider a patient's safety as top priority and each dentist must show the evidence of sound practices for the prevention of any possible medical errors. Therefore, KAPD must establish the proper sedation guidelines and it needs to provide the systematic technical training program of sedation-related emergency management for pediatric dentists.

  • This study was conducted to determine riboflavin status of young healthy Korean women. Eight subjects consumed general Korean diet for 3 weeks. Riboflavin intake was measured during the period and Erythrocyte Glutathione Reductase Activity coefficient (EGRAC) was analyzed at the end of experimental period. The subjects who showed EGRAC value above 1.20 were supplemented 6 mg riboflavin per day for 1 week. The average age of subjects was 22.1 years old, height was 154.4cm, weight was 49.2kg, chest circumference was 81.2cm, the sum of skinfold thickness of 3 parts was 79.5mm and Body Mass Index(BMI) was 20.6. Hemoglobin concentration was 13.0g/100ml, hematocrit value was 44.0% A/G ratio was 1.4, and the activity of sGOT, sGPT, alkaline phosphatase was 14.3, 11.0 and 6.5, respectively. The average daily intake of energy, protein and riboflavin was 1745kcal, 56.1g and 1.14mg, respectively. The mjor source of riboflavin were milk, egg, Korean cabbage, rice, beef and so on. The average EGRAC value was 1.2748. percentages of subjects who showed EGRAC value above 1.20 was 65.2%. After oral administration of 6mg riboflavin, the EGRAC value of all these subjects was returned to normal range. Riboflavin intake was correlated positively with energy as well as protein intake, and correlated negatively with EGRAC value. However, riboflavin intake per 1,000kcal was not correlated with EGRAC value.

  • This study develops the process and method of official administration documents which have remained ill-balanced like the official documents of the government-general of Chosun(the pro-Japanese colonial government (1910-1945)). At first, the existing Appraisal-theories are recomposed. The Appraisal-Theories of Schellenberg is focused valuation about value of records itself, but fuction-Appraisal theory is attached importance to operational activities which take the record into action. But given that the record is a re-presentation of operational activities, the both are the same on the philosophy aspect. Therefore, in the case that the process - method is properly designed, it can be possible to use a composite type between operational activities and records. Also, a method of the Curve has its strong points in the macro and balanced aspect while the Absolute has it's strength in the micro aspect, so that chances are that both alternate methodologies are applied to the study. Hereby, the existing Appraisal theories are concluded to be the mutually-complemented things that can be easily put together into various forms according to the characteristics of an object and its situation, in the terms of the specific Appraisal methodology. Especially, in the case of this article dealing with the imbalance remains official-documents, it is necessary to compromise more properly process with a indicated useful method than establishing a method and process by choosing the only one theory. In order to appraise the official-documents of the pro-Japanese colonial government (1910-1945), a macro appraisal of value has to be appraised about them by understanding a system, functions and using the historical-cultural evolution, after analysing Disposal Authority. From this, map the record so that organization function maps are constructed regarding the value rank of functions and detailed-functions. After this, establish the appraisal strategy considering the internal environment of archival agencies and based on micro appraisal to a great quantity of records remained and supplying other meaning to a small quantity of records remained for example, the oral resources production are accomplished. The study has not yet reached the following aspects ; a function analysis, historical decoding techniques, a curve valuation of the record, the official gazette of the government general of Chosun( the pro-Japanese government for 1910-1945), an analysis method of the other historical materials and it's process, presentation of appraisal output image. As the result, that's just simply a proposal and we should fill in the above-mentioned shortages of the study through development of all the up-coming studies.

  • Based on the questionnaires sent to 270 nurses of public health centers in kyungnam during the period of March 19 to April 11 in 1992, this study was written for the of finding out the grade of satisfaction, obstacles in carrying out duties concerned with nursing services and the change of nurses role needed according to the change of the local public health administration. The first-ranking tasks carried by nurses of public health center are believed to have been family planning activities before the 1970's, nursing services during the 1970's, mother-child health activities during the 1980's, and nursing services during the period of 1990 to 1992. As far as the priority order of all the family planning activities is concerned, the counseling of the insertion of intrauterine contraceptive device, the use of oral pill or the distribution of condom was placed emphasis on before 1970, and publicity activities of family planning after that time. The first priority order of mother-child health activities has been put on the registration of pregnant women since 1970, with prenatal examination and vaccination ranking next to it. The priority order for activities against tuberculosis was laid on finding out and registration of new T.B. patients every year, with patients' control, and medication or injection ranking next to it. As for the priority order of nursing services, traveling medical examination and treatment ranked the first-stressed activity before 1970, with medication and injection ranking next to it. The first priority order management activity of communicable diseases was put on vaccination before 1970, with medication and injection. ranking next. And consultation and education ranked second to it during 1990 to 1992. As for the health services of the aged, traveling examination and treatment ranked the order, with the assistance of medical examination ranking next to it. As far as troubles and obstacles shown in case of family planning, the rate of residents' lack understanding was 28.8%, that of lacking budget 13.6%, and the imperfection of public health administration system 11.9%. In the case of tuberculosis control, residents' lacking understanding was 32.5%, the deficiency of public health administration system 18.2%, over-duty(shortage of hands) 15.6%, and the insufficiency skill and know-how 13.0%. In the case of nursing services, the deficiency of public health administration system was 18.2%, each over-duty(the shortage of hands) and the shortage of facilities and equipment 15.6% respective, and residents' lacking understanding 13.0%. The rate of dissatisfaction with the chance or possibility of promotion for his or her career or capability was shown to be 49.2%, and 65.9% of the health nurses expressed their complaints of the deficiency of the chance of the promotion to a professional or expert. when the public health nurses were asked in the questionably whether they were satisfied or not with current state of equipment and facilities needed for public health service, 49.6% of them answered in the negative. The grade of the satisfaction with the current individual position was shown to be low as much as the status of his or her position was now. 37.6% of those asked in the research answered to have the readiness to switch jobs for the reasons of dissatisfaction and so on with lacking promotion chance as well as bad working condition. Significant correlation between the grade of job satisfaction and the current status of the po as found to be in this research, which showed that the lower the status of position was, the lower the grade of job satisfaction was. But little correlation between the grade of job satisfaction and his or her schooling and career was found. In order to carry out primary health care successfully, it can be said that more education and publicity activities to make public health nurses and residents see it in a new light are requested. In addition to it, it is suggested that the improvement of promotion system for public health nurses and the enlargement of job province should also be taken in consideration of the high dissatisfaction with and complaints of the chance of promotion and the system of position. In order words, it is important that considerations for system improvement enough to make nursing services pleasant and satisfactory should be taken into.
