Thalassemia major is a genetic disorder with a defective synthesis of either the alpha or the beta chain of hemoglobin A. Blood transfusion is crucial for the survival in these patients. Unfortunately, endocrine dysfunction is a very common complication in these patients and is principally due to excessive iron overload as a result of frequent blood transfusions. Although regular blood transfusion may increase life expectancy, disturbances in growth and pubertal development, abnormal gonadal functions, impaired thyroid, parathyroid and adrenal functions, diabetes, and disorderly bone growth are common side effects. We hereby present a case of a 23-year-old, unmarried woman with beta thalassemia major presenting with primary amenorrhea, poor development of secondary sexual character, and short stature. Thorough history, clinical examination, and laboratory investigation, including dynamic function test (insulin tolerance test) were conducted. These tests confirmed that she had multiple endocrinopathies, including hypogonadotropic hypogonadism, growth hormone deficiency, and subclinical adrenal insufficiency, which were caused by iron overload. She required hormone replacement therapy. Early recognition of possible deficiencies in hypothalamo-pituitary-end organ hormones caused by iron overload in thalassemia patients that undergo frequent blood transfusion procedures is essential. Appropriate treatments, including transfusion regimen and chelation therapy, as well as specific treatment of each complication are the crucial for the successful management and improvement of quality of life these patients.

We executed this experiment to observe side effects of warfarin, the anticoagulant that is used for preventing thrombus in cardiovascular surgery for calves. The 6 calves(70-130 kg) were used in this experiment regardless of sexes. We administered warfarin at 0.07 mg/kg daily for 25 days. Blood was collected before warfarin administration, every five days for 30 days. PCV, RBC, WBC, fibrinogen, total protein and platelet as blood test, prothrombin time (PT) as blood coagulation test, and AST, SDH, total bilirubin, BUN and creatinine as serum biochemical tests were measured. As the result of the experiment, PT has been gradually increased after warfarin administration. It has been gradually increased and remains within the therapeutic range from the third day to the 28th day. PCV and RBC were decreased significantly from the value before the administration (p < 0.05). In the serum biochemical test, SDH shows significant increase comparing the value before the administration (p < 0.05). AST and total bilirubin were increased gradually from the value before the administration. Considering the result of the experiment, to give wafarin to prevent thrombus in cardiovascular surgery, we can get anticoagulation effect with minimal administration(0.07 mg/kg, PO) from the third day of the administration. However because of the decreased PCV and RBC, it may cause anemia. It may cause damage to liver based on the result of serum biochemical test.

This study investigated changes in certain blood parameters in calves and pigs after foot-and-mouth disease (FMD) vaccination. In this study, five calves and five pigs were selected from groups of 10 calves and pigs, respectively, and were vaccinated with an FMD vaccine. The remaining animals formed two non-treatment control groups. Blood samples were collected from all animals on the 1st, 3rd, 5th, and 7th days post-vaccination. In the FMD-vaccinated calves and pigs on day 7 post-vaccination, white blood cell counts, blood urea nitrogen levels, and alanine aminotransferase and aspartate aminotransferase activities were higher than those in the respective controls. The present data suggested that the certain hemato-biochemical parameters on cattle and pigs were meaningfully changed between before and after FMD vaccination.

Leukemia is a neoplastic disease with an excessive proliferation of immature white blood cells and their precursors. Common oral manifestations of acute myeloid leukemia (AML) include ulceration, petechiae, spontaneous bleeding, and gingival hyperplasia. The estimated prevalence of AML is 19 per 100,000 populations, the median age of diagnosis is over 65 years, and of all the subtypes of leukemia, AML accounts for the highest percentage of leukemic deaths. The purpose of this study is to report the case of a 77-year-old female patient, who visited our outpatient clinic due to consistent inflammatory findings. Though she received surgical treatment, she was diagnosed with AML by chance after a preoperative blood test. We also discuss the necessity of performing a preoperative blood test prior to invasive dental procedures such as tooth extraction or biopsy.

본 연구는 분변 잠혈 검출 키트 (one-step FOB(Fecal Occult Blood) kit)가 법생물학적으로 매우 중요한 혈흔 검출 및 사람 혈흔 판정에 적용 가능한지 알아보고자 하였다. 먼저 FOB 키트의 민감도를 결정하고 기존의 혈흔 검사법인 LMG 검사와 비교한 결과 1,000,000배 희석된 혈액까지도 검출 되었는데 이는 LMG 검사에 비해 약100배 정도 예민한 것이었다. 다른 동물 혈액에 대한 교차 반응 여부를 실험한 결과 FOB 키트는 사람의 혈액과만 반응하여 높은 특이성을 보여주었다. 또한 혈액의 보관 온도 및 경과 시간의 영향, 고온 처리의 영향을 알아보았으며, LMG 및 Luminol 시약의 영향에 대해서도 실험하였다. 사람 혈액 특이 항원은 매우 높은 안정성을 보여주었으며, 전통적인 혈흔 검사 시약인 LMG 및 Luminol에 대해서도 영향을 받지 않았다. 따라서 FOB 키트는 LMG 검사 및 Luminol 검사와 병행하여 사용하면 보다 신속하고 정확하게 사람 혈흔 여부를 판정할 수 있어 법과학 실험실에서는 물론 사건 현장에서의 혈흔 검사에 크게 기여할 수 있을 것으로 사료된다.

Objectives: This study was designed to evaluate the efficacy and the safety of constitutional herbal tea for treating chronic fatigue with no diagnosed cause, which is called Mibyeong in Korea. Methods: Males and females with ages between 40 and 59 years who had complained of fatigue for 1 month consistently or for 6 months intermittently without a definite cause were recruited. At the same time, a Chalder fatigue scale (CFS) score of 19 was essential for participation in this study. Sixty five subjects completed the entire process, including blood tests and tests with medical devices. Five assessments of health status were accomplished over 8 weeks by using the CFS and the visual analogue scale (VAS). To ensure that the constitutional herbal tea was being safely used, we conducted and analyzed renal function and liver function tests. For the diagnosis of the Sasang constitution, the Sasang Constitutional Analysis Tool (SCAT) was used, and a specialist in Sasang constitutional medicine made the final diagnosis based on the SCAT result. Constitutional herbal tea was served four weeks after the first visit. The subjects took the constitutional herbal tea twice a day for one month. Results: The results are as follows: The CFS and the VAS scores were significantly improved for the subjects in the constitutional herbal tea. No abnormalities were found on the blood tests to evaluate safety after taking the constitutional herbal tea. The improvements in the CFS and the VAS scores due to the constitutional herbal tea had no significant differences according to the Sasang constitution. Conclusion: Constitutional herbal tea may be used to reduce fatigue and improve health and has no adverse effect on either the kidney or the liver.

반접현상(Aliasing)을 제거하기위한 방법 중 속도범위(velocity scale)를 높이는 방법은 동일 조건하에서 속도범위를 높여줌으로써 혈류의 방향이 반대로 나타나는 현상이 점차 사라지는 것을 확인할 수 있었다. Doppler angle을 $0^{\circ}$에 가깝게 하는 실험에서는 각도의 변화에 따른 스펙트럼 파형에서 유의한 차이점을 발견을 하지 못했다. 실제 초음파 검사(Ultrasonography)를 시행할 때는 검사의 편의성과 신속성, 정확성을 고려해서 속도범위에 변화를 주어 검사함으로써 보다 정확한 검사가 시행되리라고 본다. 또한 Doppler Angle에 따라 혈류속도는 기하학적으로 증가하였으며, $70^{\circ}$ 이상에서는 측정불가능 할 정도로 수치가 급상승하여 혈류속도가 Doppler Angle에 크게 의존한다는 것을 알 수 있었다. 혈류의 방향에 따른 실험에서는 입사각이 $60^{\circ}$ 이상에서 오차범위가 증가하였고, $70^{\circ}$ 이상에서는 매우 큰 차이를 보였다. 따라서 입사각은 $60^{\circ}$ 이하가 적당하다고 보며, 사지 혈관(extremity vessel)의 혈류속도를 구하는 데 있어서 Doppler 각도는 $45^{\circ}$에서 $60^{\circ}$가 적절한 것으로 사료된다.

Background: Workers in pesticide manufacturing industries are constantly exposed to pesticides. Genetic biomonitoring provides an early identification of potential cancer and genetic diseases in exposed populations. The objectives of this biomonitoring study were to assess DNA damage through comet assay in blood samples collected from industry workers and compare these results with those of classical analytical techniques used for complete blood count analysis. Methods: Samples from controls (n = 20) and exposed workers (n = 38) from an industrial area in Multan, Pakistan, were subjected to various tests. Malathion residues in blood samples were measured by gas chromatography. Results: The exposed workers who were employed in the pesticide manufacturing industry for a longer period (i.e., 13-25 years) had significantly higher DNA tail length ($7.04{\mu}m$) than the controls ($0.94{\mu}m$). Workers in the exposed group also had higher white blood cell and red blood cell counts, and lower levels of mean corpuscular hemoglobin (MCH), MCH concentration, and mean corpuscular volume in comparison with normal levels for these parameters. Malathion was not detected in the control group. However, in the exposed group, 72% of whole blood samples had malathion with a mean value of 0.14 mg/L (range 0.01-0.31 mg/L). Conclusion: We found a strong correlation ($R^2=0.91$) between DNA damage in terms of tail length and malathion concentration in blood. Intensive efforts and trainings are thus required to build awareness about safety practices and to change industrial workers' attitude to prevent harmful environmental and anthropogenic effects.

Objective: This study aimed to assess the safety and effect on glucose level of Bojungikgi-tang in patients with type 2 diabetes mellitus. Methods: To review patients' clinical characteristics and laboratory tests retrospectively, we investigated 15 hospitalized patients with type 2 diabetes mellitus who took Bojungikgi-tang at Kyung Hee University Korean Medical Hospital for at least one day between January 2012 and December 2022. The blood glucose levels, including fasting blood sugar (FBS), 2-hour postprandial glucose (PP2) levels, and glycated hemoglobin level, were collected to determine the effect of the Bojungikgi-tang on blood sugar changes. Furthermore, to evaluate the safety of Bojungikgi-tang, hepatic function and renal function tests were implemented, including aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, blood urea nitrogen, creatinine, and Modification of Diet in Renal Disease estimated glomerular filtration rate. Results: When Bojungikgi-tang and a standard treatment for diabetes were administered for patients with type 2 diabetes, it was confirmed that there were no statistically significant changes in FBS and PP2 levels in the analysis of each medication taken. There was no significant difference in the safety profile after taking Bojungikgi-tang. Conclusions: The combined administration of Bojungikgi-tang with standard hypoglycemic medication for patients with type 2 diabetes may not affect blood glucose levels and safety.
