The increase of triglyceride in blood can be a signal of an increasing danger of arterial diseases when insulin resistance. diabetes. HDL -cholesterol decrease is accompanied. It is adjusted to triglyceride level in blood by a balance. which seems to be absorbed from VLDL metabolism in liver and by lipoprotein lipase activity. The hyper-triglyceride disease treatment proposal role should match with suppression does into liver or elimination of a triglyceride. (omitted)

Blood chemistry values according to ages have rarely been investigated in indigenous Korean calves. The present study aimed to clarify the changes in blood chemistry values of indigenous Korean calves with age. Blood samples were collected from 29 calves (11 females and 18 males) reared at the Gyeongsangbukdo Livestock Research Institute and the levels of various chemical components in the serum were analyzed. The total protein, albumin and globulin concentration in the calves increased gradually over time. The glucose concentration increased significantly at 2 weeks after birth, and then decreased slightly 4 weeks after birth. The blood urea nitrogen concentration increased from 2 weeks after birth, and the levels in females were higher than those in males at 2 and 4 weeks after birth. The creatinine concentration decreased significantly from 2 weeks after birth, and the levels in females were higher than those in males at 2 weeks and 6 months after birth. The total bilirubin concentration decreased gradually from 2 weeks after birth. The glutamic oxaloacetic transaminase and glutamic pyruvic transaminase concentration increased gradually from 2 weeks after birth. The triglyceride concentration tended to increase from 2 weeks after birth. The total cholesterol concentration increased significantly at 2 weeks after birth, and then decreased slightly 4 weeks after birth. The total high density lipoprotein cholesterol concentration increased significantly from 2 weeks after birth. The calcium concentration was maintained between $9.8{\pm}0.8mg/dL$ and $11.6{\pm}0.9mg/dL$ throughout the investigation period, although some levels fluctuated at 4 weeks and 6 months after birth. The phosphorus concentration increased significantly at 2 weeks after birth, and then decreased slightly 4 weeks after birth. In conclusion, the data obtained from this study may be valuable for use as a standard for interpreting results of blood biochemical analyses in indigenous Korean calves.

Nonactin을 이온운반체로 사용한 암모늄선택성 전극막 위에 urease를 고정시킨 형태의 요소센서는 혈액 중 여러가지 이온으로부터 방해작용을 받을 수 있다. 이 방해작용은고정화된 효소반응보다는 암모늄선택성 전극막 자체의 부적합한 선택성의 기인한 것이며 본 연구에서는 혈액 중의 요소를 측정할 경우 이들 방해이온에 의해 발생된 오차를 보정하고자 하였다. 이를 위해 혈액 속에 각 방해이온의 정상 평균농도를 포함하고 있는 용액을 검정용액으로 사용하여 이들 방해이온으로부터의 오차를 감소시키고자 하였다. 또한 칼륨이온선택성 전극을 부가적으로 사용하여 요소전극의 측정치를 보정하여 오차를 최소화하고자 하였다. 이와 같은 방법들에 의해 보정된 측정치의 오차는 보정하지 않았을 경우에 비해 현저히 감소함을 알 수 있었다.

In the present research, a simple electrochemical sensor based on a carbon paste electrode (CPE) modified with ZnO-Zn₂SnO₄-SnO₂ and graphene (ZnO-Zn₂SnO₄-SnO₂/Gr/CPE) was developed for the direct, simultaneous and individual electrochemical measurement of Acetaminophen (AC), Caffeine (Caf) and Ascorbic acid (AA). The synthesized nano-materials were investigated using scanning electron microscopy, X-ray Diffraction, Fourier-transform infrared spectroscopy, and electrochemical impedance spectroscopy techniques. Cyclic voltammetry and differential pulse voltammetry were applied for electrochemical investigation ZnO-Zn₂SnO₄-SnO₂/Gr/CPE, and the impact of scan rate and the concentration of H⁺ on the electrode's responses were investigated. The voltammograms showed a linear relationship between the response of the electrode for individual oxidation of AA, AC and, Caf in the range of 0.021-120, 0.018-85.3, and 0.02-97.51 μM with the detection limit of 8.94, 6.66 and 7.09 nM (S/N = 3), respectively. Also, the amperometric technique was applied for the measuring of the target molecules in the range of 0.013-16, 0.008-12 and, 0.01-14 μM for AA, AC and, Caf with the detection limit of 6.28, 3.64 and 3.85 nM, respectively. Besides, the ZnO-Zn₂SnO₄-SnO₂/Gr/CPE shows an excellent selectivity, stability, repeatability, and reproducibility for the determination of AA, AC and, Caf. Finally, the proposed sensor was successfully used to show the amount of AA, AC and, Caf in urine, blood serum samples with recoveries ranging between 95.8% and 104.06%.

A novel inhibitory protein against blood coagulation factor Va (FVa) was purified from muscle protein of granulated ark (Tegillarca granosa, order Arcoida, marine bivalvia) by consecutive FPLC method using anion exchange and gel permeation chromatography. In the results of ESI-QTOF tandem mass analysis and database research, it was revealed that the purified T. granosa anticoagulant protein (TGAP) has 7.7 kDa of molecular mass and its partial sequence, HTHLQRAPHPNALGYHGK, has a high identity (64%) with serine/threonine kinase derived from Rhodopirellula baltica (order Planctomycetales, marine bacteria). TGAP could potently prolong thrombin time (TT), corresponding to inhibition of thrombin (FIIa) formation. Specific factor inhibitory assay showed that TGAP inhibits FVa among the major components of prothrombinase complex. In vitro assay for direct-binding affinity using surface plasmon resonance (SPR) spectrometer indicated that TGAP could be directly bound with FVa. In addition, the binding affinity of FVa to FII was decreased by addition of TGAP in dose-dependant manner ($IC_{50}$ value = 77.9 nM). These results illustrated that TGAP might interact with a heavy chain of FVa ($FVa_H$) bound to FII in prothrombin complex. The present study elucidated that non-cytotoxic T. granosa anticoagulant protein (TGAP) bound to FVa can prolong blood coagulation time by inhibiting conversion of FII to FIIa in blood coagulation cascade. In addition, TGAP did not significantly (P < 0.05) show fibrinolytic activity and cytotoxicity on venous endothelial cell line (ECV 304).

We studied blood salvage effect of Cell Saver Apparatus[CSA with adult cardiac patients. This study compares blood salvage in two groups of patients undergoing valve replacement or congenital cardiac operation.Group 1 is composed with 60 patients operated during 1991-1992 using CSA. Group 2 is composed with 60 patients operated during 1990-1991. No special effort was made to salvage blood in Group 2. The average requirements in Group 1 were approximately one-fourth the amount of RBC products by Group 2. The hospital course, blood chemistry level were comparable for the two groups. CSA produced blood was concentrated, well oxygenated blood and the average amount was 830 ml. Any complication was not detected in transfusion of CSA produced blood. This study shows that CSA allows safe and practical blood salvage during adult cardiac operations.

시안화수소는 ABS (acrylonitrile-butadiene-styrene) 등의 플라스틱류 화재시에 발생될 수 있는 유독성 기체이기에 시안화수소가 함유된 연기를 흡입하였을 경우 변사자의 혈액에서도 검출될 수 있다. 따라서 열기로 혈액 등의 생체시료의 손상정도가 강하여 일산화탄소-헤모글로빈 농도의 측정이 어려운 경우 사인규명을 위한 지표로 활용될 수 있으리라 사료된다. 본 연구의 사례는 유서와 함께 화재가 발생한 차량내에서 발견된 변사체의 사인규명과 관련이 있다. 화재사의 경우 일산화탄소-헤모글로빈 농도가 결정적인 정보를 제공하지만 열기로 심하게 손상되어 이에 대한 측정이 어려워 시안화이온을 분석하고자 하였다. 시안화이온을 양이온계면활성제와 함께 pentafluorobenzyl bromide로 유도체화 시킨 다음 기체크로마토그래피/질량분석법으로 scan mode와 SIM mode로 분석하였다. 변사체 심혈과 뇌혈에서 시안화이온이 정상 흡연자 14인의 평균값(0.041 µg/mL)보다 높은 0.36 µg/mL 및 1.20 µg/mL 확인되었다.
