  • Deer Antler has been known for its traditional oriental medicinal properties and has been widely used to promote growth, boost immune function, treat blood loss and chronic joint pain. Recent study showed imported (New Zealand) Deer Antler was beneficial in reducing the side effects of cancer treatments. However, there was no intervention study conducted on the effect of Korean Deer Antler on reducing the oxidative stress to patients with diabetes. One of the sensitive ways to measure endogenous oxidative stress is by measuring cellular DNA damage using single cell gel electrophoresis (COMET assay). This study was conducted to investigate the possible beneficial effect of commercial Deer Antler drink (provided by Chung-yang Deer Farm) on lymphocyte DNA damage and blood glucose of diabetic patients. Ten patients (4 men, 6 women) participated in the study and consumed 2 pouches of Deer Antler drink every day for 20 days. Blood was collected on the morning before and after the intervention for lymphocyte isolation and blood glucose analysis. Both systolic and diastolic blood pressure showed a tendency to decrease but did not reach statistical significance after the trial. Blood glucose level was not affected by the supplementation. After the intervention, over 50% reduction were noted in the cellular DNA damage, expressed as tail length (TL) and tail moment (TM: tail length ${\times}$ percent tail DNA) . Although we did not obtain beneficial effect on lowering blood glucose levels in the patients, this results suggest that Deer Antler may initially act in protecting endogenous DNA damage in short-term experiment.

  • This study was conducted to determine the effects of added rice bran fiber on the physicochemical and sensory characterization of blood sausage. Blood sausages were supplemented with rice bran fiber at levels of 0% (control), 1%, 2%, and 3%. The moisture, hardness, gumminess, and chewiness of treatments with added rice bran fiber were higher than those of controls (p<0.05). The pH, lightness, redness, and yellowness of uncooked as well as cooked blood sausages increased with increasing addition levels of rice bran fiber levels, but energy values were lower in blood sausage treatments with containing rice bran fiber than that of controls (p<0.05). As the increase levels of rice bran fiber in blood sausage the energy levels were decreased (p<0.05). All sensory scores of treatments containing rice bran fiber were higher than controls, and the highest overall acceptability was attained when 2% rice bran fiber was added to blood sausage. The blood sausage with 2% rice bran fiber can be manufactured with high quality characteristics.

  • Chemical bonded nonwoven fabric for apparel use and spunlaced nonwoven fabric for medical use were finished for soil resistance and blood replellency with fluorochemicals utilizing foam finishing technology (FFT) and conventional padding application techniques. The FFT process improved soil and abrasion resistance properties of nonwoven fabrics compared with the conventional padding process. Excellent water-oil-saline-alcohol repellency values and water impact penetration values were obtained in the spunlaced nonwoven fabrics with both techniques.

  • This paper is the study of the reflectance of light from biological tissue for red and Infrared wavelengths and relates the acquired reflectance data to expected physiological changes within the skin and muscle layers associated with heat and exercise. The instrument was disigned to collect data from the calf muscle in human subjects with probe located at the surface of skin. Rapid data acquisition method allowed monitoring of rapid changes in reflecttance due to a stimulus. This study demonstrates that changes in O2 saturation and blood fractional volume expected within the dermis and muscle layers were asserted by examining the slopes of the plotted index for heat and exercise. The results presented in thls study support the claim that reflectance can separately discriminate between changes of blood volume and oxygenation in muscle and in skin. The data demonstrate the ability to measure consistent changes In tissue optical properties during exercise and heat.

  • Wireless magnet pumps are used in medical applications and are particularly useful as artificial heart ventricular assist devices (VADs). To investigate wireless operation of magnetic pumps, we fabricated three types of magnetic impellers using bonded magnets by blending magnetic powders of SmFeN, NdFeB, and Sr-ferrite. We investigated the magnetic properties of the fabricated magnetic impellers, which are driven by the application of magnetic coupling with an external driving magnet or external coil system, without a driving motor, shaft, or mechanical bearings. The use of wireless magnetic pumps is therefore not complicated by critical issues of size, heat, and vibration, which are very important issues for blood pumps. The magnetic properties of the impellers, such as their rotational speed, driving torque and hydrodynamic performance, determine their wireless driving ranges. We conducted performance evaluations of the impeller's magnetic wireless manipulation, heat, and vibration. In addition, we carried out an animal test to confirm the suitability of the wireless magnetic pumps for use as biventricular assist devices (BiVADs).

  • Tinospora crispa (L.) is a medicinal plant traditionally used to treat various ailments including diabetes. The stem has been widely studied for its antidiabetic properties, however the antidiabetic potential of its leaves has not been explored. This study investigates the antidiabetic properties of methanolic T. crispa stem and leaves extracts on alloxan-induced diabetic rats. The stems and leaves were extracted using Soxhlet extraction with methanol as solvent. Crude extracts were administered at 500 mg/kg body weight (BW) (high dose) and 250 mg/kg BW (low dose) via oral route to alloxan induced diabetic rats. T. crispa stem and leaves extracts was found to significantly reduce blood glucose following a twelve-week treatment period. The highest mean difference in blood glucose level was exhibited by animals in the high dose treated stem and low dose leaf extracts. Both extracts showed approximately 75% percentage recovery from hyperglycaemia. The highest regenerative capacity was observed in animals treated with the low dose leaf extract.

  • This study was carried out to investigate the effect of phytosterol ester addition on lowering blood cholesterol in cholesterol-reduced Cheddar cheese. For cholesterol removal, separated cream was treated with 10% ${\beta}$-cyclodextrin at 800 rpm, then blended with remaining skim milk and homogenized with 1,000 psi at $70^{\circ}C$. Experimental cheeses were manufactured by five different levels of phytosterol addition. After the cholesterol reduction process by ;${\beta}$-cyclodextrin, the cholesterol removal rate was in the range of 91.0 to 92.1%. Amount of short-chain free fatty acid and free amino acids increased with an increase of phytosterol ester, and those were significantly different from that of control in all ripening periods. All rheological properties also increased with an increase of phytosterol ester during ripening period. In sensory analysis, the scores of rancid, bitterness Cheddar flavor and off-flavor intensities increased significantly, while texture was decreased during ripening in phytosterol ester-added groups. Total blood cholesterol was reduced by 18% when rats were fed Cheddar cheese treated with 8% phytosterol. The present study indicated that phytosterol ester addition resulted in a profound lowering effect of blood with cholesterol-reduced Cheddar cheese.

  • Radio-cephalic arteriovenous fistula(RC-AVF) is the most recommended operation of achieving access for hemodialysis. However, it has high rates of early failure depending on the many haemodynamic conditions. To increase RC-AVF patency rate, many researches were performed by in-vitro experiment via artificial vessel and blood analogue fluid, and there were conflicting opinions about whether the non-Newtonian properties of blood have an influence on the flow in large arteries. To investigate the influence of viscoelasticity of blood within the RC-AVF, we fabricated three dimensional artificial RC-AVF and two kinds of blood analogue fluid. The velocity field of two fluids within the vessel were measured by micro-particle velocimetry(m-PIV) and compared with each other. The velocity profiles of both fluids for systolic phase were matched well while those for diastolic phase did not correspond. Therefore, it is desired to use non-newtonian fluid for in-vitro experiment of RC-AVF.

  • We preformed many treatments to preserve Kim-gu's relics (Baekbum-ilgi and the clothes stained with blood). The first we performed re-paper mount of binding area of baekbumilgi, and fumigated all relics to sterilize microorganism. Then all relics were sealed with biaxially oriented polyvinyalcohol film(BO-PVA film) and $N_2$ gas filled up in the BO-PVA film bags. We investigated the paper condition of Baekbum-ilgi, its brightnees was 25-35%, water content was 9.4%, and acidity was pH 4.3. These results indicated that the paper was very weak. On the other hand, We analyzed his blood type and genetic type with the solidified blood of the clothes. In result, his blood type was AB and were classified 6 genetic types such that HUMTH01 was 7-9 type, HumTPOX was 9-11 type, HumCSF1PO was 12-13 type, HumF13A01 was 4-4type, HumFESFPS was 12-12, and HumvWA was 18-18 type.
