This study was carried out to investigate the prevalence of Neopsora (N) caninum infection in Korean dairy herds. To determine the prevalence of antibodies to N caninum in Korean dairy cattle, a total of 1,688 sera including 895 sera taken from 30 herds having recent high abortion rate and 793 sera selected randomly from 168 herds with no history of recent abortion problem, respectively, collected nationwide during a designated period were analyzed by indirect fluorescent antibody (IFA) test. Mean nationwide seropositive rate of the sera tested in herds and individual cattle tested were 53.5% and 35.6%, respectively. However mean seropositive rate of the samples from herds having abortion problem was approximately two and half times higher than those in herds with no recent abortion history. Regional seropositive rates of the samples from the herds with abortion problem were 48.6%, 51.6%, 44.4% and 71.4% at Kyunggi, Kangwon, Kyungbuk and Jeonnam province, respetively. Regional seropositive rates of the samples from the herds with no recent abortion problem were 35.6%, 18.3%, 16.5%, 37.5%, 19.4%, 33.3%, 32.1%, 3.8% and 0.0% at Kyunggi, Kangwon, Chungbuk, Chungnam, Kyungbuk, Kyungnam, Jeonbuk, Jeonnam and Jeju province, respectively. The results of this study suggested that N caninum infection was widespread and considerably associated with bovine abortion in Korea.

Background: About one third of the human population suffer cancer during their lifetime and more than 20% of total morbidity is related to neoplasia. Cervical cancer is generally the most common cancer in developing countries and the second most common in women globally. The role of human papilloma viruses viruses in its induction is clear. However, the involvement of hepres simplex virus type 2 (HSV-2) is controversial. Therefore a survey was conducted of the prevalence of HSV-2 in patients with cervical cancer and also healthy people with sensitive and quantitative Taq Man real-time PCR assay. Materials and methods: Seventy six formaldehyde fixed paraffin embedded tissue specimens from patients with histologically proven history of cervical cancer as well as 150 control blocks were sectioned for deparaffinization and DNA extraction. Results: There was no HSV-2 DNA in our patient specimens but four control samples were positive, all with a history of hysterectomy. Conclusion: Considering the absence of any positive viral HSV-2 DNA in our patients and also the presence of four positive specimens among our controls, we did not find any relationship between the presence of HSV-2 DNA and cervical cancer.

Life table experiments were performed in order to examine the effects of food quality on Moina macrocopa fed with four kinds of algal foods, Botryococcus sp., Scenedesmus subspicatus, Selenastrum capricornutum, and Chlorella sp., at $20^{\circ}C$ . The temperature effects on M. macrocopa were also assessed, feeding Chlorella at $17^{\circ}C$,$20^{\circ}C$,$25^{\circ}C$, and a combination of $28^{\circ}C$ (light) and $25^{\circ}C$ (dark). The cartilaginous Botryococcs cells were Inappropriate food for Moina. Among the foods tested, Chlorella was the food of the best quality in all accounts of life history traits. Moina grown on Chlorella showed higher net reproductive rate ($R_0$), longer mean and maximum longevities, earlier mean age at maturity, longer mean carapace length at maturity, larger mean clutch size, and shorter mean time interval between clutch productions than those grown on Selenastrum and Scenedesmus. An optimal temperature for Moina was $20^{\circ}C$ . When Moina were grown on Chlorella at $20^{\circ}C$, they showed the highest r, the highest $R_0$, the shortest T, the longest mean longevity, the earliest mean age at maturity, the longest mean carapace length at maturity, and the largest mean clutch size. The results of life table experiments showed that the individual and population growth patterns were much more affected by low temperature $17^{\circ}C$, than by high temperature ($\geq 20^{\circ}C$). In the optimal condition, the r value was very high, 5.1 in $d^{-1}$. In conclusion, the food quality and the temperature are the most important factors to govern the size and continuity of Moina population, by which the individual growth rates and reproductivity of members in the population can be controlled to survive in their environment such as small and temporary water bodies in nature.

Exposure to lead, particularly at chronic low-dose levels, is still a major public health concern. The present study is aimed to evaluate the blood lead levels in populations resident in some abandoned mine areas of Chungbuk, Korea. Eight hundreds and sixty-six subjects who reside in abandoned mine area located in Chungbuk, Korea, were enrolled this study. We evaluated the blood lead level according to the age, gender, and working history in mines. For statistical analysis, SPSS ver 12.0 was used. The geometric mean blood lead levels was $2.93\;{\mu}g/{\ell}$ and nobody showed levels over the guidelines of WHO. Ex-smokers and current-smokers showed significantly higher blood lead levels compared to that of non-smokers. The blood lead levels in individuals with a history of working in a mine was higher than those in individuals without such histories. The populations resident in some Chungbuk abadoned mine area showed low levels of lead in blood. This suggest that lead poisoning might not be induced by abandoned mine in Chungbuk, Korea.

This study focuses on the origin and the literature of eyelid-acupuncture, nunchim therapy in Korea and its present clinical usage in modern Korea. The therapy is called nunchim at local area of Korea and has been transmitted as folk remedy because its real practice has been fallen into oblivion in the regular medical institution in modern Korea. On the contrast, some old women called nunchim-halmae, still know its practice and give medical therapy in a certain irregular way. While many kinds of eye clinics are prevalent in Korea, some patients with chronic eye diseases still go to get the nunchim therapy from nunchim-halmae. Moreover some oriental medical doctors have learned the therapy from nunchim-halmae and performed that medical service in their clinics in spite of absence of medical insurance coverage. Nunchim has unique historic origin and transmission linage in Korea, which was shed light on by this research. We present concise structure of the essence of nunchim therapy and 80 year old woman case of dramatic eye curing with the therapy.

To evaluate the relationship between obesity, diet, physical activity and breast cancer in Thai women, we conducted a case control study with 1,130 cases and 1,142 controls. Informed consent was obtained from all participants and a structured questionnaire was performed by trained interviewers to collect information on demographic and anthropometric data, reproductive and medical history, residential history, physical activity and occupation as well as dietary habits. A significant positive association with an increased risk of breast cancer was observed in women body mass index (BMI) of ${\geq}25mg/m^2$ (OR=1.33, 95%CI 1.07-1.65), the risk being higher in postmenopausal women (OR=1.67, 95%CI 1.24-2.25). In addition, underweight BMI at ages 10 and 20 years showed an inverse association in all women (OR=0.70, 95%CI 0.56-0.88 and OR=0.74, 95%CI 0.59-0.93, respectively) and in those with a premenopausal status (OR=0.69, 95%CI 0.51-0.93 and OR=0.76, 95%CI 0.56-0.99, respectively). Regular exercise was associated with a decreased risk of breast cancer (OR=0.78, 95%CI 0.68-0.98). Interestingly, analysis by type of activity revealed significant protective effects for women who reported the highest levels of walking for shopping (OR=0.58, 95%CI 0.38-0.88). High consumption of vegetables and fruit were associated with a decreased risk of breast cancer, while high consumption of animal fat showed an increased risk in postmenopausal women. In conclusion, our results indicate that obesity and high consumption of animal fat are associated with breast cancer risk, particularly in postmenopausal women, while recreational physical activity has protective effects. It seems that primary prevention of breast cancer should be promoted in an integrated manner. Effective strategies need to be identified to engage women in healthy lifestyles.

The effect of the relative abundances of planktonic foraminifera juveniles on the climatic and oceanographic history interpretations is documented for the first time (as far as we know) by use of the year-long time-series sediment trap samples. Statistical correlation analysis suggests that many climatic and oceanographic variables such as sinking flux (total number) of planktonic foraminifera, relative abundance of some climatic indicator species G. bulloides and N. dutertrei, temperature, and salinity do not show any significant correlations with the relative abundance of planktonic foraminifera juveniles. However, planktonic foraminifera juveniles show moderate correlations with species diversity indices (species richness, Shannon-Wiener index, and Equitability). These indicate that the juveniles do not affect the relative abundances(%) of species compositions but affect the species diversity indices. Based on this one-year trap result, special care is required when we use species diversity indices for the interpretations of paleoceanography when the juveniles are excluded from total planktonic foraminiferal countings.

We investigated to egg development and early life history of Tribolodon brandtii in the Korean peninsula. The fertilized eggs of the T. brandtii were slightly adhesive and separated with a yellow yolk and no oil globule, and they was an average of $2.4{\pm}0.2mm$ in diameter. The hatching of the embryo took place in about 60 hrs after fertilization under water temperature of $20{\pm}1^{\circ}C$ and the newly hatched larvae were average $6.4{\pm}0.4mm$ in total length. At 10 days after hatching, they were average $11.7{\pm}0.2mm$ in total length and their yolk sac were completely absorbed. At 46 days after hatching, they became to juvenile stage and reached $19.6{\pm}2.7mm$ in total length and all their fin rays were formed. At 125 days after hatching, the juvenile were $54.9{\pm}15.8mm$ in total length and their body shape were similar to the adult fish. At 236 days after hatching, they fish were $54.9{\pm}15.8mm$ in total length and their body color were similar to the adult fish.
