  • Poly(ethylene glycol)s (PEGs) are unique in their material properties, such as biocompatibility, non-toxicity, and water-solublizing ability, which are extremely useful for a variety of biomedical applications. In addition, a variety of functional PEGs with specific functionality at one or both chain ends have been synthesized for many specialized applications. Surface modifications using PEG have been demonstrated to decrease protein adsorption and platelet or cell adhesion on biomaterials. Furthermore, PEGs having anionic sulfonate terminal units have been proven to enhance the blood compatibility of materials, which has been demonstrated by the negative cilia concept. The preparation of telechelic PEGs having a sulfonic acid group at one end and a polymerizable methacryloyl group at the other is an interesting undertaking for providing macromers that can be used in various vinyl copolymerization and gel systems. In this paper, preliminary results on the synthesis and polymerization behavior of a novel PEG macromer is described with the aim of identifying a biocompatible material for applications in various blood-contacting devices.

  • Tyroid gland is the biggist endocrine organ which is located in front of trochea. The role of the thyroid gland in the total body economy comprises the synthesis, storage, and secretion of thyroid hormones, which are necessary to growth, development, and normal bodymetabolism. Hypothyroidism is the state of a dificiency in the secretion of Thyroid hormone. This may result from idiopathic myxedema, or distruction or removal of thyroid, or goiter, or thyroid adenomas. Hypothyroidism corresponds to thick lips, dry skin, puffy eyelids, coars hair, megaloglossia, and pudgy hands etc. On one case of Hypothyroidism who was hospitalized for the chief complaints of fatigue, general weakness, coldness, edema in head, neck site, lumbago. I diagnosed this case as dificiency of Qi and blood(氣血兩虛) or dificiency of warm-Qi in spleen and kidney(脾腎陽虛). And then I used Moxa treatment to increase Qi and blood, and Acupuncture treatment to reduce shoulder and neck pain, lumbago. And Herb-med is used to increase Qi and blood, and recover of general condition. As a result, this patient got better more quickly.

  • The study was undertaken to obtain indirect values of volume of packed red cell (VPRC) without centrifugation, using the erythrocyte sedimentation rate (ESR) of diluted blood in dogs. ESRs of diluted blood using the diluent of autologous plasma in which formed numerous RBC-rouleau clumps, autologous serum in which formed a few RBC-rouleau clumps, and 5% dextrose or 6% sucrose solutions in which formed numerous RBC-aggregation clumps, were accelerated. But, ESR of diluted blood using the 0.9% saline, D-S, ACD-B, CDP or D-PBS solutions were sluggish, because erythrocytes were dispersed in these diluents. Reliable values of VPRC on the basis of the correlating regressive equation to the ESR could be derived from values of$60^{\circ}$-angled-micro-ESR/40 min in the mixture, four parts of 5% dextrose solution and one part of whole blood. In the ESR values of diluted blood with low ratio, 1:1~3:1, $60^{\circ}$-micro-ESR was higher than $60^{\circ}$-Wintrobe-ESR. But, in the diluted blood with high ratio, 4:1~5:1, there was no different ESR values. For an aid of practical use, authers suggested a list of the $60^{\circ}$-micro-ESR/40 min in the diluted blood with equivalent VPRC of whole blood.

  • To Appreciate the value of bone scintigraphy in determination of the bony infection, we performed three phase bone scintigraphy in 34 cases of osteomyelitis of extremities prospectively. They were clinically inactive in 11 and active in 23 cases. We confirmed the active osteomyelitis by operation or aspiration within one week after scintigraphy. Perfusion, blood pool and delayed images were analyzed respectively and compared with the plain roentgenograms. All 23 active lesions showed diffusely increased perfusion in affected limbs. The areas of the increased activities on blood pool images were larger than or similar to those on delayed images in 17 cases (73.9%) with active osteomyelitis and smaller in 6 cases (26.1%). 5 of the latter 6 cases showed definite soft tissue activities on blood pool images. In inactive cases bone scintigrams were completely normal in 4 cases. Two of those were normal on plain films and remaining two showed mild focal bony sclerosis. Among 7 inactive lesions, perfusion was normal in 2 cases, diffusely increased in 4 cases and diffusely decreased in 1 case. 6 of these 7 cases showed increased activities both on blood pool and delayed images and the areas of increased activities on blood pool images didn't exceed those on delayed images. Bony sclerosis was noted on plain films in those 7 inactive lesions and the extent of the sclerosis correlated well to delayed images. Large blood pool activity was characteristics of active osteomyelitis. Normal three phase bone scintigram may indicate the time to terminate the treatment, but increased activity on perfusion and blood pool scans is not absolute indication of active lesion if the extent of the lesion on the blood pool image is smaller than that on delayed image and if no difinite soft tissue activity is noted on perfusion and blood pool images in clinically inactive patient.

  • Objective: Two series of experiments were conducted to determine how the incremental levels of sodium metabisulfite (SMB)-treated fruit and vegetable discards (FVD) in diet of Hanwoo heifers and cows affect their performance and health. Methods: In Exp. 1, 36 Hanwoo heifers were stratified by age (13.3±0.83 mo) and initial body weight (305±19.7 kg), and divided randomly to one of three diets containing 0%, 10%, or 20% SMB-treated FVD (as-fed basis). The experiment lasted 110 d, including 20 d of adaptation. In Exp. 2, 24 multiparous Hanwoo cows were divided into three groups based on age (48.2±2.81 mo) and initial body condition score (2.64±0.33). Cows in each block were assigned randomly to one of three diets containing 0%, 11%, or 22% SMB-treated FVD (as-fed basis). The experiment lasted 80 d, including a 20-d adaptation period. In both experiments, SMB-treated FVD was used as a replacement for wet brewers grain in total mixed ration (TMR). Results: Growing heifers exhibited no differences in their daily feed intake (6.58±0.61 kg/d dry matter [DM]), average daily gain (0.60±0.07 kg/d), and body condition score when they consumed the incremental levels of SMB-treated FVD. Although most blood metabolites were unaffected by treatments, blood urea-N and β-hydroxybutyrate levels decreased linearly as the SMB-treated FVD level increased in TMR. Similar to Exp. 1, minor differences were found in daily feed intake (8.27±0.72 kg DM/d) and body condition score of Hanwoo cows. Most blood metabolites remained unaffected by treatments, but blood urea-N decreased as the SMB-treated FVD level in TMR increased. Conclusion: Our findings suggest that SMB-treated FVD could be safely incorporated into the diet of Hanwoo heifers and cows, potentially improving N-use efficiency in the body while not impairing performance or health.

  • To investigate a possible effect of pectinate(apple and carrot) and alginate (tangle or green laver) on blood pressure and sodium retention, male spontaneous hypertensive rats (SHR) were assigned to 5 different experimental groups and fed diets containing 5% dietary fiber and 1% NaCl for 3 weeks. Dietary fibers were provided from one of the followings : cellulose, freeze dried apple, carrot, tangle(Undardia pinnatifda) or green laver(Monostroma nitidium). Fecal sodium excretion did not change significantly among the groups, however, urinary sodium excretion was increased in groups fed either carrot. tangle or green laver compared to group fed cellulose. Sodium balance was also negative in groups fed either carrot, tangle or green laver. most effectively in green laver group. Blood pressure of groups fed apple. carrot. tangle or green laver were decreased, especially those of group fed tangle, compared to those of group fed cellulose. Dietary fiber containing alginate. such as tangle and green laver, might have cellular binding capacity to sodium so that increased urinary sodium excretion and decreased blood pressure occur.

  • Background: Lung cancer is the leading cause of cancer death, late diagnosis being the main obstacle to improving the outcomes with stage at diagnosis as an important prognostic factor. Relationships between ABO blood groups and risk of benign or malignant diseases have been observed and in this study, we aimed to investigate whether they might affect prognosis and response to chemoradiotherapy in patients with local advanced non-small cell lung cancer (NSCLC). Materials and Methods: Eighty-one patients with non-metastatic local advanced NSCLC were included in the study. ABO blood groups were A in 45 (55.6%), B in 7 (8.6%), AB in 8 (9.9%), and O in 21 (25.9%) patients. The patients were also divided two groups according to blood group A (45 patients) and non-A (B, AB and O; 36 patients). Response to chemoradiotherapy was complete remission in 10 (12.3%), disease regression in 42 (51.9%), stable disease in 12 (14.8%), and disease progression in 17 (21.0%) patients. Results: There was no significant difference among ABO blood group categories or between patients with A blood group and those with non-A blood group in terms of responses to chemoradiotherapy (p>0.05). There were also no significant differences regarding overall and disease-free survival rates. Conclusion: The ABO blood group system has no significant effect on prognosis and response to chemoradiotherapy in patients with non-metastatic NSCLC.

  • This study examined the factors affecting blood donation intention and behavior in college students based on the theory of planned behavior. The subjects were 258 students from one college in G city, and the data was collected by a survey using self-administered questionnaires structured from June 3 to June 14, 2013. The data was analyzed using the SPSS 19.0 program, the variables affecting the blood donation intention were analyzed by stepwise multiple regression, and the variables affecting the blood donation behavior were analyzed by Logistic regression. The factors affecting the blood donation intention were in order the perceived behavioral control, attitude toward the behavior and subjective norm, and the explanatory power was 65.6%. In addition, the factor affecting the blood donation behavior was only the blood donation intention (OR=1.129, p=.010) except for perceived behavioral control. Therefore, the perceived behavioral control, attitude and subjective norm should be considered when developing blood donation programs for college students.
