  • The study was conducted to assess the repeated dose and reproduction and developmental toxicities of acetanilide, an intermediate for drug production, as a part of OECD Screening Information Data Set (SIDS) program. The test agent was administered by gavage at dose levels of 0, 22, 67, 200 and 600 mg/kg to Sprague-Dawley rats (12/group/sex) during pre-mating and mating period for males(up to 30 days) and females and pregnancy and early lactation period for females (up to 39-50 days). At 22 mg/kg, decreases in HGB, HCT (males) and MCHC (females), hyperplasia of spleen red pulp, hyperplasia of femur bone marrow (both sexes) were observed. At 67 mg/kg, salivation (males), reduced food consumption (both sexes), decreases in RBC, HGB, HCT and MCHC (males), increases in MCV (males) and spleen weight (males), hyperplasia of spleen red pulp and femur bone marrow (both sexes) were observed. At 200 mg/kg, decreases in locomotor activity and salivation (both sexes), reduced food consumption (both sexes), decreases in RBC, HGB, HCT and increases in MCV, MCH, BUN, T-BIL (males), enlargement of spleen (both sexes), increased weight of spleen (males), hyperplasia of spleen red pulp and femur bone marrow and extramedullary hematopoiesis of liver (both sexes), atrophy of thymus and corpus luteum hyperplasia of ovary (females) were observed. At 600 mg/kg, decreases in locomotor activity, cyanosis (both sexes), reddish tear, and salivation (males), mortality (4 out of 12 females), decreased body weight (females), reduced food consumption (both sexes), decreases in RBC, HGB, HCT and MCHC and increases in WBC, MCV, MCH, reticulocyte, neutrophil, lymphocyte, monocyte, AST, ALT, BUN, T-BIL, ALB, Ca and A/G ratio (males), enlargement of spleen, increased weights of spleen (both sexes), liver (males), kidney and ovary, decreased weights of thymus (females), hyperplasia of spleen red pulp, hyperplasia of femur bone marrow and extramedullary hematopoiesis of liver (both sexes), and atrophy of thymus and corpus luteum hyperplasia of ovary (females) were observed. Regarding the reproduction and development toxicities, there were no treatment-related changes in precoital time, mating index, fertility index and pregnancy index at all doses tested. At 22 and 67 mg/kg, there were no adverse effects on all the parameters observed. At 200 mg/ kg, decreased body weight of pups (day 4 p.p.) were observed. At 600 mg/kg, decreased body weight of pups (day 0 and 4 p.p.) and viability index (day 4 p.p.), increased incidence of newborns dead or with abnormal clinical signs were observed. The results suggest that the NOAELs for general toxicity are < 22 mg/kg, LOAELs are 22 mg/kg and the NOAELs for reproductive toxicity are 67 mg/kg.

  • This study was conducted to compare the endocrine milieu, and pregnancy rates in In Vitro Fertilization and Embryo Transfer(IVF-ET) program employing combined with gonadotropin releasing hormone agonist(GnRH-a) and pergonal(LH 75lU+FSH 75lU) when either human chorionic gonadotropin(HCG) or progesterone were used for luteal phase support. A total number of 40 IVF-ET treatment cycles were prospectively studied. Ovarian hyperstimulation method was modified ultrashort protocol using GnRH-a. All patients started Decapeptyl at menstrual cycle day # 2, and HMG was started at # 3 days. When leading follicle was ${\geqq}$18mm or at least two follicles were ${\geqq}$14mm in diameter, HCG 10000lU intramuscularly was injected. After 36 hours HCG administration, oocytes were retrieved as usual guided by transvaginal ultrasound. Embryo were transfered 36-48 hours later. The patient's cycles were prospectively randomized to receive HCG(20cycles) or Progesterone (20cycles) for luteal support. The progesterone group received 25mg 1M starting from the day of ET. The HCG group received 1500IU 1M. on days 0, +2, +5 after ET. Estadiol($E_2$) and Progesterone($P_4$) were measured on the day of oocyte aspiration, ET day, and every 6 days thereafter. Results were follows as; 1. Estradiol, progesterone and LH levels on the day of HCG trigger, retrieved oocytes and number of transfered embryo were not significantly different in both groups. 2. On the day of aspiration and embryo transfered day, $E_2$, $P_4$ level were significantly higher in progesterone group than HCG group(p<0.01). 3. $E_2$, $P_4$ level on 6 days after ET were significantly higher in progesterone group than HCG group(p<0.01). But, $P_4/E_2$ ratio was not different in both groups. 4. $E_2$, $P_4$ level 12 days after ET were decreased abruptly in both groups and higher hormonal level appeared in HCG group(P<0.01). 5. The total pregnancy rate in the HCG group was 40% (8/20) and in the progesterone group 15%(3/20). 6. Comparing the pregnant and nonpregnant cases progesterone group was not different the hormonal status. In HCG group, pregnant cases appeared in higher $P_4$, $P_4/E_2$ ratio than nonpregnanct cases(P<0.01).

  • Extract of Lentinula edodes mycelia (LEM) is currently utilized as an oral biological response modifier (BRM) medicine for cancer patients. However, its effectiveness for breast cancer patients with postoperative adjuvant hormone therapy has not yet been scientifically verified. In this study, we investigated the influence of LEM on the quality of life (QOL) and immune response in breast cancer patients undergoing postoperative adjuvant hormone therapy. Twenty patients were studied in total. They received only hormone therapy in the first 4 weeks followed by hormone therapy and LEM during the next 8 weeks. Laboratory tests, QOL score and peripheral blood cytokine production levels were evaluated during the study period. No changes in QOL or cytokines were noted after the first 4 weeks. In contrast, during the following combined therapy period, improvements were noted in QOL and cytokine levels. Although a future large-scale investigation is necessary to confirm these results, these data suggest that the concomitant use of LEM with postoperative adjuvant hormone therapy improves the QOL and immune function of patients.

  • It has been claimed that artificial insemination (AI) of cows with frozen-thawed semen treated with commercially produced kits, Wholemom (in favour of female gender) increases the birth chance of calves with desired sex ratio by approximately 85% without decrease of pregnancy rates. Hence, this study was conducted to investigate the efficacy of wholemom kits as combined with frozen-thawed bovine semen during in vitro fertilization on the in vitro fertilization and developmental efficiency and sex ratios such as some reproductive parameters in bovine. For this, 1,737 oocytes were in vitro fertilized and developed. Agglutination effects on bovine after treatment of Wholemom kit were observed by time passage and dose respectively. To determine sex of embryos, Bovine embryo Y-specific gene primers(ConEY) and Bovine specific universal primer(ConBV) were used as multiple PCR method. Fertilization rate of wholemom-treated group was significantly lower than its of control group[66.9% (1,156/1,737) in Wholemom-treated group; 75.0% (610/813) in control group]. However, developmental rate after fertilization of both wholemom-treated and control groups were not significantly different [26.1% (404/1,156) in Wholemom-treated group; 27.4% (224/610) in control group]. Sex ratio of in vitro fertilized embryo with frozen-thawed semen treated with wholemom kit was determined by multi PCR. Female ratio in wholemom-treated group [85.4% (173/201)] was significantly higher than its of control group [47.2% (66/141)]. In conclusion, wholemom treatments of semen used in the in vitro fertilization and development of bovine oocytes provided increase in female ratio with decrease of fertilization rate.

  • In this study we analysed time allotment and the contents of a health textbook and its teacher's guide book of the 7th elementary curriculum. We intended to offer the basic data needed to establish the single health education. So the analysed results are as follows according to the health education model developed by the korean nursing association and health teachers' meeting and the teaching time allotment presented by the teacher's guide book. It's goal is practice in regular class time of the subjects for the time and contents of health education in the 7th elementary curriculum. The total class periods of health education of the 7th elementary curriculum are 229 hours and annual periods of health education per year are an average of 38 hours. The health education of the 7th elementary curriculum is separated into the 9 following subjects: Wise life, Pleasant life, Righteous life, We are 1st grade, Physical education, Science, Social studies, moral education and Practical course. The health education of the 6th elementary curriculum was combined with the units of physical education, but in the 7th curriculum it must be separated by a single, required health subject. The contents of health education of the 7th elementary curriculum is mostly dominated by units of community and environmental health with a total of 55 hours (24%). Therefore, the units of home health and social health, development of physical strength are fairly insignificant. The newly added contents in the 7th curriculum are "pregnancy and child birth, the protection and counterplan from rape, the reasons and prevention of stress, the reasons and the treatment of obesity, the damage of smoking and drinking, etc. According to the result above, we must establish the criteria for each year's health education in the 8th elementary curriculum. The contents of mental health, home health and social health should be revised and added new items. The health education that is separated in some subjects now must be established as a systematically integrated health education.

  • 1. Definition : Bee-venom therapy does not involve actual bee-stings: it is a treatment method with acquired bee-venom extract through the electric stimulus on the bee, It is injected subcutaneusly on the acupuncture point after refining, according to the diagnosis of constitution and disease. 2. History : Around 2000 B.C., records that Bee-venom was used for therapy were written in the medical book of Babylonia and Papirus of ancient Egypt. Hippocrates, who is called the father of Medicine, said that Bee-venom is Arcanum, which means mysteric medicine. In Oriental medicine, B.C. 200, there was a clinical record that the meat suspended in front of the bee house on the tree in order to get bee-venom, was attached on the lesion. 3. Mechanism of Action : There are two aspects: 1) The effect of stimulating acupunture point It is similar to the chemical moxa. I think that there are several methods of stimulating the acupuncture point: For example, a simple needle is a mechanical stimulus, Moxa is a heating stimulus and electric and Raser acupunture etc. And another stimulus: in the ancient orient, a chemical stimulus called Chungu(Tianjiu), is attached to the lesions by using grinded insects (ex. Mylaris phalerate PALL.) which have toxin. So Bee venom therapy is similar to this. 2) The effect of biochemical ingredients Bee venom consists of 40 kinds of ingredients. For example, me Iii tin, Apamin, Pospholipase A2, MCD peptide, Adolapin and so on. They have effects which have been proven through experimentation l) tonifying mechanism of the body through increasing hormon secretion 2) tonifying immune system through proliferation of WBC, lymphocytes, macrophage 3) anti-inflammatory reaction Therefore Bee venom therapy is the representative 3rd Medicine, which combined East & West medicine. 4. Application of disease : L.B.P and HIVD, O.A, R.A, degenerative arthritis, shoulder pain and other pain diseases. 5. Therapic methods : According to constitution and disease, proper concentration of bee venom is injected on acupunture point, 2 times a week. Generally one term is consisted of 15times. 6. Contraindication : Heart disease, TBc, DM, kidney disease(nephritis), pregnancy, woman in menstruation 3-4 persons per 100,000 persons may have severe allergic reaction.

  • Down syndrome (DS) is an abnormality of the 21st chromosome that commonly occurs in children born to older women. Thus, amniotic fluid (AF) is usually collected from such women for prenatal diagnosis. This study analyzed human AF supernatants (AFS) using a mass spectrometric (MS) approach to search for candidate biomarkers of a DS pregnancy. The AFS were collected from older pregnant women at weeks 16-18 of their gestation by amniocentesis for cytogenetic analysis. The AFS from the pregnancies carrying DS (n=4) or chromosomally normal (n=6) fetuses, as revealed by the cytogenetic analysis, were then subjected to global protein profiling based on liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Affinity chromatography was also applied prior to the LC-ESI-MS/MS to minimize the masking effect of highly abundant albumin and immunoglobulin and thereby increase the diversity of the identified proteins. As a result, at least 30 new AFS proteins were identified and 44 AFS proteins were found to be differentially expressed between the DS and normal cases, where 6 of the proteins were unique to the DS cases and 11 were unique to the chromosomally normal cases. In addition, in the DS cases, 19 AFS proteins were downregulated and 8 were upregulated to varying degrees. A Western blot analysis confirmed the LC-ESI-MS/MS data, indicating that the combined detection of apolipoprotein A-II (apoA-II) and alpha-fetoprotein (AFP) could be a potential tool for diagnosing DS cases.

  • Objectives : Examined the editing system and the characteristics of "Clinical Formula Science of Korean Medicine" to establish a basis for compilation system of the common formula science textbook for colleges of Korean medicine nationwide. Methods : Comprehended the "Clinical Formula Science of Korean Medicine" published by professor Hyeongok(1911-1987) in 1985 and analyzed its configuration system. Results : "Clinical Formula Science of Korean Medicine" has made it possible to understand the formula systematically by establishing and classifying 24 kinds of treatment method [the three treatment methods of cold-dampness, dryness-heat and interior deficiency and its subdivision, 19 kinds of treatment method (stomach, phlegm, eum, yang, spirit, essence, ki, blood, blood stasis, exterior, interior, half-exterior half-interior, water, wind, cold, heat, dampness) combined with reducing and vomiting] and main formula. These can be considered as professor Hyeongok's own method of classification, which is distinctive from the existing formula science system. Also, it suggests that a Korean medicine doctor should not use a biased formula science that is limited to some schools but apply the formula widely and synthetically because it is believed to pursue perfection in cure if the main formulas related to a physical disorder, pregnancy and childbirth, invigorating and purging five viscera, and Four-Constitution Medicine are added. Conclusions : "Clinical Formula Science of Korean Medicine" is seen as a formula science book which is to be consulted when compiling a common formula science textbook for colleges of Korean medicine by forming a Korean formula science system that is distinctive from that of China.

  • The objective of this study was to evaluate the effect of dietary undegradable protein (UP) level on body weight change, nutrient intake, milk production and postpartum reproductive performance of Awassi ewes. Twenty-seven multiparous Awassi ewes (initial body weight = 53.3${\pm}$1.6 kg) were randomly assigned to three dietary treatments (9 ewes/treatment) for 62 days using a completely randomized design. Experimental diets were isonitrogenous (15.5% CP), isocaloric, and were formulated to contain 17.9 (LUP), 27.1 (MUP), and 34.0% (HUP) of the dietary CP as UP. On day 10${\pm}$3 (day 0 = parturition) ewes were housed in individual pens for 5 weeks. Feed offered and refused was recorded daily. At the end of this period, animals were removed from their pens and combined into 3 separate groups (LUP, MUP and HUP). One fertile, harnessed ram was allowed with each group for 34 days. Rams were rotated every 2 days among the three groups. Each group was offered the corresponding experimental diet. Organic matter, CP, UP and metabolizable energy intakes were higher (p<0.05) for ewes fed the HUP diet compared with ewes fed the LUP and MUP diets. Ewes fed the HUP diet gained more (p<0.05) weight compared with ewes fed the MUP diet (7.3 vs. 2.1 kg), while ewes fed the LUP diet lost an average of 2.1 kg. Pregnancy rate of ewes fed the HUP diet was 100%, compared with 66 and 33% for ewes fed the MUP and LUP diets, respectively. Lambing rate was greater (p<0.05) for ewes fed HUP (8/9) diet compared with ewes fed the MUP (4/9) and LUP (3/9) diets. These results indicate that Awassi ewes receiving adequate dietary UP level consume more feed and are capable of returning to estrus shortly after parturition and are capable of producing two lamb crops per year.

  • Brown tumor is tumor like lesion resulted from hyperparathyroidism, and it has been rarely reported recently. We evaluated a 29-year-old woman who had brown tumor on proximal humerus caused by primary hyperparathyroidism. She first had presented pain and swelling over the upper arm, and was suspected as giant cell tumor in biopsy combined with hyperparathyroidism. Wide marginal excision and tumor prosthesis were performed. However, it was confirmed as brown tumor resulted from parathyroid adenoma according to laboratory findings and radioactive isotopes image, and surgical excision of adenoma relieved clinical symptoms. We report this case with a review of literatures.
