Plasma progesterone concentrations were measured by using radjoimmunoassay for early diagnosis of pregnancy in Cheju-native mares. A total of 226 pony mares were examined for pregnancy during breeding and non breeding seasons. Plasma progesterone levels 20~23 days after the onset of oestrus were 4.67+O.67ng /rnl and O.55+O.O4ng /ml for mares becornrning pregnant and not pregnant after the estrus, respectively, and there was a significant differences (p<0.01) between the two groups. Progesterone concentration of pregnant mares gradually increased in 30 days andreached a peak (10.3ng /ml) during the third month of gestation. However, the concentration decresed to the base line (1.llng /rnl) at 7 months and gradually increased again as foaling approached (2.lng /ml). Early diagnosis for pregnancy of Cheju mares by progesterone level at 20~23 days after onset of oestrus was 88% accurate when 4.6ng /ml was used to classify mares as pregnancy and below 1.3ng /rnl was used to determine nonpregnant mares. However, the accuracy of the diagnosis was improved to 96% when a progesterone level of above 2ng /mi was used to classify mares for pregnancy. Diagnosis for pregnancy was 69.6% accurate when mares were classified as pregnancy by horse owners during breeding season. The progesterone levels of pregnant and non-pregnant mares during non-breeding season varied greatly between individual animals, Plasma progesterone levels of pregnant animals ranged from 3.5ng /mi to above 6.2ng /mi whereas similar values were observed in non-pregnant animals. Radioirnrnunoassay technicjues can be applied for the early pregnant diagnosis of Cheju native mares when progesterone levels are measured during the early gestation period (18~23 days after onset of oestrus). However, progesterone concentration of mares in non-breeding season is conisidered unsuitable as a indicator of pregnant diagnosis.

The cells that make up the body continuously undergo cell division to maintain life, but stress and carcinogens, and physiological stimuli suppress immunological functions in the body and change cells to cancerous cells. The only way to overcome cancer is by treatment through early detection and proper diagnosis. However, because early stage of cancer shows subjective symptoms that are similar to those of other common illnesses, even doctors have difficulty separating cancer from common illnesses in its early stage. However, the Ki(bioenergy) present in our body recognizes and changes to the most minute changes in the body. This method of detecting the change in bioenergy to discover a disease in the early stage to raise treatment success is called the OBET: O-Ring, Bioenergy Test. This method, which is based on the theories of oriental medicine, focuses on tumors, especially malignant tumors, and has shown value in diagnosis and treatment, as witnessed in the clinical applications. The diagnosis method and cases of OBET: O-Ring, Bioenergy Test are presented.

The radiographic diagnosis of osteomyelitis can be suspected early with deep soft tissue swelling, but the actual bone changes of osteomyelitis may be delayed as long as 10 to 14 days after onset or may be totally aborted by antibiotic therapy. Recognition of osteomyelitis by bone imaging is far more rapid than by conventional radiographic examination and can be used on admission to establish the diagnosis. Ten patients suspected of having early, acute osteomyelitis were studied by TC-99m Pyrophosphate bone imaging. Radiographs taken at the same time were all negative. Of these 9 patients showed positive bone images. The bone imaging provides a safe, accurate, noninvasive technique for the early diagnosis of osteomyelitis.

Early diagnosis and early treatment of human immunodeficiency virus (HIV) infection are essential for clinical and public health benefits. Diagnostic algorithms for early diagnosis are being emphasized, and rapid tests at the point of care have been expanded to improve voluntary testing rates. Despite advances in laboratory diagnostic tests, early HIV infection can still be missed due to window periods, and it is crucial to recognize the limitations of testing methods and the potential for false negative and false positive results.

Ultrasonographic diagnosis of genital disease and early pregnancy diagnosis was performed in Korean native cattle. The size of ovarian follicle in preovulation, luteal stage and follicular cyst was 18.9, 9.2 and 27.6 mm, respectively, and the thickness of follicular wall was 2.3, 1.8 and 2.8 mm, respectively. The size of corpus luteums in formation stage, activity stage, regression stage, cystic corpora lutea and luteal cyst was 6.2, 11.3, 8.6, 26.7 and 25.9 mm, respectively. The thickness of luteal wall in cystic corpora lutea and luteal cyst was 8.4 and 4.9 mm, respectively. The size of embryo or fetus on day 25, 27, 30, 35, 40, 45 and 50 was 0.8, 0.9, 1.3, 1.5, 2.2, 2.8 and 3.8 cm, respectively. The size of amniotic vesicle on day 25, 27 and 30 was 1.2, 2.1 and 3,0 cm, respectively. The diameter of pregnant uterus on day 25 and 27 was 7.0 and 7.8 cm, respectively. It was concluded that the ultrasonographci values determined in this study can be used as references for the treatment of genital disease and early pregnancy diagnosis in Korean native cattle.

Objective: To summarize and evaluate various urinary markers for early detection, diagnosis and follow-up of human bladder cancer. Methods: A MEDLINE and PUBMED search of the latest literature on urinary markers for bladder cancer was performed. We reviewed these published reports and made a critical analysis. Results: Most urinary markers tend to be less specific than cytology, yielding more false-positive results, but demonstrating an advantage in terms of sensitivity, especially for detecting low grade, superficial tumors. Some tumor markers appear to be good candidates for early detection, diagnosis, and follow-up of human bladder cancer. Conclusion: A number of urinary markers are currently available that appear to be a applicable for clinical detection, diagnosis, and follow-up of bladder cancer. However, further studies are required to determine their accuracy and widespread applicability.

With the increasing number of children with inflammatory bowel disease (IBD), very early-onset IBD (VEO-IBD), defined as IBD that is diagnosed or that develops before 6 years of age, has become a field of innovation among pediatric gastroenterologists. Advances in genetic testing have enabled the diagnosis of IBD caused by gene mutations, also known as monogenic or Mendelian disorder-associated IBD (MD-IBD), with approximately 60 causative genes reported to date. The diagnosis of VEO-IBD requires endoscopic and histological evaluations. However, satisfactory small bowel imaging studies may not be feasible in this small population. Both genetic and immunological approaches are necessary for the diagnosis of MD-IBD, which can differ among countries according to the available resources. As a result of the use of targeted gene panels covered by the national health insurance and the nationwide research project investigating inborn errors of immunity, an efficient approach for the diagnosis of MD-IBD has been developed in Japan. Proper management of VEO-IBD by pediatric gastroenterologists constitutes a challenge. Some MD-IBDs can be curable by allogenic hematopoietic stem cell transplantation. With an understanding of the affected gene functions, targeted therapies are being developed. Social and psychological support systems for both children and their families should also be provided to improve their quality of life. Multidisciplinary team care would contribute to early diagnosis, proper therapeutic interventions, and improved quality of life in patients and their families.

Forty one patients with para-aortic node metastases from carcinoma of the uterine cervix treated with radiotherapy at Department of Radiation Oncology, Yonsei University, College of Medicine from January 1982 to December 1987 were retrospectively analyzed. Eleven patients were diagnosed at the time of diagnosis of carcinoma of the cervix (early diagnosis) and 30 patients were diagnosed during follow up period after definitive radiotherapy of primary site (late diagnosis). The most important factors affecting the survival in this study were time of diagnosis and dose of irradiation. Overall 5 year actuarial survival rate of 41 patients was $25.7\%$. Five year survival rate for early diagnosis was $60.3\%$, but late diagnosis was $16.9\%$. And survival rate for high dose (over 4000 cGy) radiation group and low dose radiation group were $42.2\%\;and\;8.9\%$ respectively The most leading cause of death was para-aortic node failure, so early diagnosis and maximum palliation with full dose radiotherapy (over 4000 cGy) is necessary to improve the survival and the quality of life.

Mucopolysaccharidosis (MPS) I is a rare, progressive and multisystemic disease with insidious initial signs and symptoms, and making an early diagnosis can be a challenge for the first-line general medical practitioner. We report a 6-month-old girl who was brought to our well baby clinic for regular immunization with the manifestations of lumbar gibbus, hirsutism, large Mongolian spots over back and buttock, and mild bilateral legs spasticity noticed by the general pediatrician, and then newly diagnosed with MPS I after referral to the geneticist in time. Her surgical history included inguinal hernia repair at 1 month old, $CO_2$ laser supraglottoplasty for laryngomalacia and tracheostomy due to chronic respiratory failure with ventilator dependence at 2 months old. Understanding and identification of the early signs and symptoms of this disease have the potential to early diagnosis and timely appropriate treatment, which could contribute to a better clinical outcome.

In our country, cardiovascular disease (CVD) and Coronary heart diseases (CHD) are the leading causes of death. It is well known that CHD is multifactorial, involving environmental factors such as diet, level of exercise and cigarette smoking, and inherited factors. According to the statistical data in 2003, the cause of death with the highest mortality was including hypertension, ischemic heart disease and atherosclerosis, which accounted for $24.7\%$ of total mortality. In spite of, there have been few study reports on the change of biochemical markers and mechanisms concerned. The development of biochemical markers is required for an early diagnosis and treatment of cardiovascular diseases that are related with dietary habits of Korean people enjoying mixtures of traditional dietary style and westernized food-styles. Therefore, the most efficient cost-saving biochemical marker was established in this study, through analysis of biochemical markers related with dietary habits which are susceptibly being changed in association to cardiovascular diseases from the pre-disease phase, and through reanalysis and assessment of early diagnosis of and preventive effects of diagnosis of cardiovascular diseases by demographical character including sex, age, and socioeconomic level with use of biochemical markers that are identified and selected among the parameters in consideration of the effectiveness and appropriateness of early diagnosis of diseases. The appropriateness of biochemical markers was reviewed by professionals (medical, pharmaceutical area and food/ nutrition area) and CRP(C-Reactive Protein) and was identified to be possible in Korea. It is thought that these biochemical markers may be used as the basic data for early diagnosis and prevention of cardiovascular diseases (CVD) which may be used for Korean people.
