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.

Cancer is now the main cause of increasing mortality throughout the world. Minor alterations in the cell cycle which are inherited and not removed by apoptosis are important rsik factors. Blood cancers are asmong the types which most readily cause death. Here in this study, usual but important factors such as age, gender, Rh and ABO blood typing, weight, and platelet counts are analyzed for impact on blood cancers. Frequencies and distributions, correlations and chi-square test were utilized in order to clarify the perspective of important factors. Our statistical results show males and females to have same risk in blood cancer but A blood type (40%) along with positive Rh (73%) had the highest risk. Low platelet counts are related to more than 80% of cases. Obesity has a statistically ignorable role in blood cancer prevalence. The fact that blood cancer cases increase during the second decade of life (45.7%) which might be because of involvement of maturation processes.

Ultrasonography is one of the fields on the imaging studies within intra-abdominal organs. A blood test is a typical method of clinical chemical examination on the in vivo test of clinical symptoms. Fatty liver is performed simultaneously two kinds of diagnostics methods, intra-abdominal ultrasound and blood tests. At an implementing this, the standard of blood tests value was the TBIL, TC, AST, ALT, ALP, GGT, TG, HDL-C, GLU. In this study analyzing the accuracy of the two kinds of test, ultrasonography and blood test, on patients with fatty liver. From January to March 2012, patients 459 determined fatty liver within 1350, who received health examination simultaneously on the intra-abdominal ultrasonography and blood tests. Same result of ultrasonography and blood test's patients were 459 ie, 60.8%. and different result of those examinations was 280 ie, 39.2%. Consequently diagnostic accuracy was 60.8%. It presumably caused by differences in the diagnostic performance of ultrasound professionals(Radiologist or Radiological Technologist). In order to overcome this, ongoing educational and study will be needed.

Objectives : In order to investigate the toxicity of rats after oral administration of Eumcheonyijin-tang extract. Methods : The experimental animals were subdivided into control, short term administration group, and long term administration group. With changes of gross appearance, the histological changes of liver and kidney were observed. Blood chemical indexes used in this study were AST, ALT, total bilirubin, albumin, BUN and creatinine in serum. Results : In the long term administration group, histological changes were detected in the liver as centrolobular disposition of fatty tissue(adipose cell), and in serum test, AST, ALT increased at 21 days after administration group, serum total bilirubin were increased 21, 28 and 35 days after administration group. So it seems to induce toxicity. Kidneys of the long term administration group revealed histological changes : increasing of connective tissue and pyknosis of glomerulus cell were observed at 28 days after administration group, and in serum test, significant changes of albumin, BUN, and creatinine were admitted. So it seems to induce toxicity. Conclusions : In long term administration of Eumcheonyijin-tang toxicity was induced.

Platelet adhesion onto elastic polymeric biomaterials was tested in vitro by perfusing human whole blood at a shear rate of 100 sec$\^$-1/ for possible verification of mechanisms of initial platelet adhesion perfusion of blood on the polymeric substrates was performed after treatments either with or without pre-adsorption of 1% blood plasma, and either with or without residence of the protein-preadsorbed substrate in phosphate buffered solution. The surfaces employed were elastic polymers such as poly(ether urethane urea), poly(ether urethane), silicone urethane copolymer, silicone rubber and poly(ether urethane) with the anti-calcifying agent hydroxyethane bisphosphate. Each polymer surface treated was exposed in vitro to the dynamic, heparinized whole blood perfused for upto 6 min and the surface area of platelets initially adhered was measured by employing in situ epifluorescence video microscopy. The blood perfusion was performed on the surfaces treated at the following three different conditions: directly on the bare surfaces, after protein pre-adsorption and after residence in buffer for 3 days of the surfaces protein pre-adsorbed for 2 h. The effects of blood plasma pre-adsorption on the initial platelet adhesion was surface-dependent. The amount of the adsorbed fibrinogen and the surface coverage area of the adhered platelets were dependent on the surface conditions whether substrates were bare surfaces or protein pre-adsorbed ones. To test an effect of possible morphological (re)orientations of the adsorbed proteins on the initial platelet adhesion, the polymeric substrate pre-adsorbed with 1% blood plasma was immersed in phosphate buffered solution for 3 days and then exposed to physiological blood perfusion. The surface area of the platelets adhered on these surfaces was significantly different from that of the surfaces treated with protein pre-adsorption only. These results indicated that platelet adhesion was dependent on the surface property itself and pre-treatment conditions such as blood perfusion without any pre-adsorption of proteins, and blood perfusion either after protein pre-adsorption or after subsequent substrate residence in buffer of the substrate pre-adsorbed with proteins. Understanding of these results may guide for better designs of blood-contacting materials based on protein behaviors.

In this study, multi-chambered single autoinjector(2in1) and KMARK-1 containing atropine and 2-PAM(pyridine-2-aldoxime methylchloride) were administered to the beagle's muscle, and blood samples were taken for a certain period of time to compare and evaluate the pharmacokinetic profiles of the two drugs. Male beagles were used and classified into two test groups(G1, G2), and crossover pharmacokinetic studies were performed in two test groups. Blood samples were collected from the jugular vein for analysis after administration. The 90 % confidence interval(CI) for log transformed data indicated that the Cmax for both atropine(log 0.9683 ~ log 1.113) and 2-PAM(log 0.9453 ~ log 1.214) was within the limits of bioequivalence criteria, but the AUC for atropine(log 1.1786 ~ log 1.3238) failed to meet this criteria. This is expected as the amount of atropine dose is 25 % higher for the test as compared to the reference formulation. In summary, in view of the ATNAA(antidote for nerve agent of US) authorization, the Cmax equivalence was more important than AUC equivalence, so in this study, we also focused on verifying the equality of Cmax between the two autoinjectors.

A flexible Packaging scheme, which embedded chip packaging, has been developed using a thinned silicon chip. Mechanical characteristics of thinned silicon chips are examined by bending test and finite element analysis. Thinned silicon chips ($t<50{\mu}m$) are fabricated by chemical etching process to avoid possible surface damages on them. These technologies can be use for a real-time monitoring of blood pressure. Our research targets are implantable blood pressure sensor and its telemetric measurement. By winding round the coronary arteries, we can measure the blood pressure by capacitance variation of blood vessel.

A dog which was hospitalized to Veterinary Teaching Hospital, College of Veterinary Medicine, Jeonbug National University on December 28, 1988 was revealed severe anemia: hemoglobinuria and weakness. In the inspections, abdominal pain and spleno megaly at the ventral abdomen were detected by palpations. In the examinations of blood, the obtained results were summarized as follows: Babesla spp. was identified on the blood smear stained with Giemsa. The Babesia spp. was assumed to the Babesia gibsoni for the their small size and pleomorphism such as comma form, ring form and dot form. In the blood examinations of the patient, Ht: 22.5％, RBC:354${\times}$10$^4$/${\mu}\ell$, Hb: 8.8g/dl, serum protein: 8g/dl, and WBC count was 21, 425/${\mu}\ell$. In the chemical examinations of serum, the value of AST(GOT) was 30iu and ALT(GPT) was 20iu, respectively. The blood sugar was 60mg/d1. In the urine test, urine protein was 30mg/d1 and the hemoglobin In the urine was the ＋＋＋ and occult blood reaction(Benzidine test) in the feces was ＋＋＋. Splenomegaly was confirmed by X-ray examination. To confirm for the Babesia spp. infection, 5ml of the whole blood of the patient(3％ of Parasitized erythrocytes) were inoculated into the cephalic vein of the two normal dogs. In the blood of experimental dogs which were inoculated parasitized blood, Babesia spp. was detected in the two doss and pleomorphic parasites were observed, too. In the blood examinations of No. 1 the Ht and RBC were decreased to 6.8％ and 52${\times}$10$^4$/${\mu}\ell$, respectively. WBC count was 10.600/${\mu}\ell$ and serum protein was 6.8g/dl. The rates of parasitized erythrocytes were 15％ in the experimental dog. Also ＋＋＋ of the hemoglobin was detected in the urine. In the X-ray examination, splenomegaly was comfirmed and it was confirmed by autopsy of the experimental dog(No. 1).

Even though driving under the influence of drug (DUID) is a worldwide problem, we, Korea has no regulation system yet except for alcohol, and there are little cases reported related to DUID. In order to investigate the type of abused drugs for drivers in Korea, we tried to analyze controlled and non-controlled drugs in alcohol-positive blood samples. 275 whole bloods, which were positive for alcohol on the roadside test, were collected from the police for two months ($Nov.{\sim}Dec.$ 2006). The analytical strategy was constituted of three steps: First, alcohol in blood samples were confirmed and quantified by gas chromatography. Second, controlled drugs were screened by $Evidence_{investigator}\;^{TM}$ (Randox, U.K.) as preliminary test. It was based on immunoassay by biochip array analyzer. Nine groups of drug abuse were screened: amphetamines, methamphetamines, cannabis, cocaine, opiates, barbiturates, methadone, benzodiazepines I (oxazepam) & II (lorazepam). Finally, confirmation of these drugs was performed by GC-MS. Blood samples were extracted by solid-phase extraction by $RapidTrace^{TM}$ (Zymark, U.S.A.). After trimethylsilyl (TMS) derivatization, eluates were analyzed to GC-MS. Total 49 drugs were investigated in this study including controlled drugs, antidepressants, 1st generation antihistamines, dextromethorphan, nalbuphine, ketamine, etc. For rapid detection, we developed the automated identification system. It was made up a new software, "DrugMan", modified Chemstation data analysis menu and newly developed macro modules. A series of peak selection, identification and reporting of the results were performed automatically by this system. Concentrations of alcohol in 275 blood samples were ranged from 0.011 to 0.249% (average, 0.119%). Among 149 blood samples, just six samples (4.0%) were showed positive results to the immunoassay: one methamphetamine and five benzodiazepines group I. By GC-MS confirmation, only benzodiazepines were detected and methamphetamine was not detected from immunoassay positive blood sample. Besides these drugs, 5 chlorpheniramines, dextromethorphan, diazepam, doxylamine, ibuprofen, lidocaine and topiramate were also detected in whole bloods by GC-MS. Conclusively, the frequency of drug abuse for Korean drivers was relatively low. There was none case which illegal drug was detected. However these results were limited to alcohol positive blood samples, so it is necessary to analyze more samples including alcohol negative blood.
