Purpose: The purpose of this study was to evaluate the effects of Internet education on plasma glucose and serum lipids in female type 2 diabetic patients. Method: Control and experimental groups were assessed by a pre-test and at 3 months, 6 months, 9 months, and 12 months. Fourteen patients were assigned randomly to an intervention group and 15 to a control group. Patients in the intervention group were requested to input their blood glucose levels everyday by cellular phone or wire Internet for 1 year. The goal of the intervention was to keep blood glucose concentrations close to the normal range (glycosylated hemoglobin, HbA1c<7%). An intervention was applied to the intervention group weekly for 1 year. Optimal recommendations were sent weekly by a short message service from a cellular phone and wire Internet. Results: Patients in the intervention group had a significant mean change in HbA1c, from 7.6% at pre-test to 6.9%, at 3 months and equalized at 6.7% at 12 months. There was no significant time and group differences observed in the serum lipids. Conclusion: These findings indicate that Internet education would improve and maintain the normal range of HbA1c in female type 2 diabetic patients.

Olive flounder Paralichthys olivaceus (total weight 216.4±14.6 g, total length 28.4±1.7 cm) were exposed to different pH levels (3, 4, 5, 6, 7, 8, and 9) for 96 h. At pH 4, hemoglobin decreased significantly, while plasma calcium, glucose, cholesterol, and ALP increased significantly. Exposure to pH 4 also induced stress responses, as evidenced by a significant decrease in heat shock protein 70 (HSP 70) and a significant increase in cortisol. The results of this study indicate that acute exposure to acidic or alkaline pH (pH 3 or 9) induced significant mortality, while exposure to pH 4significantly affected hematological parameters and stress responses in P. olivaceus.

The purpose of this study was to investigate the anthropometry, biochemical parameters and electrolytes concentrations of the Total Parenteral Nutrition (TPN) patients according to their nutritional status at the time of admission. Thirty-three patients in the Intensive Care Unit at S University Hospital were the subjects of this study. Their nutritional status was classified as At-risk I (Mild PCM, n = 13), At - risk II (Moderate PCM, n = 9) and At-risk III (Marasmus + kwashiorkor + severe PCM, n = 11) . Anthropometeric, biochemical and dietary assessments were performed. The Patients intake of calories (75.02%) and protein (53.15%) was insufficient compare with Korean RDA requirements. The body weight and the Body Mass Index (BMI) in the At-risk III group were significantly lower than in the other groups. The percentage of body weight loss and change of body weight (kg) were significantly higher than in the other groups. The subjects were malnourished as indicated by nutritional related parameters such as serum total protein, albumin, total lymphocyte count (TLC), hemoglobin and hematocrit. Serum total protein, albumin and TLC levels were lower at the time of admission before TPN administration. But after TPN administration, they increased. The electrolyte concentrations did not show any differences following TPN administration. The nutritional status of the patients could be affect by the duration of TPN administration and the number of days of the patients hospitalization. The patients who require nutritional support need the continuous follow-up care and monitoring by a nutritional support team. (Korean J Community Nutrition 8(4) : 574-583, 2003)

Biodegradable films were prepared by solution blending method in the weight ratio of Chitosan and Algin for the purpose of useful bioimplants. The possibility of bioimplants, which prepared from natural polymers as a skin substitute and food wrapping materials were evaluated by measuring the biodegradability. these biodegradable films were inserted in the back of rats and their biodegradability was investigated by hematological change as a function of time. Rats study showed that low-Chitosan induced increments of monocyte and basophil after 48 hours of implantation. And medium-Chitosan showed increase of lymphocyte and decreased neutrophil counts after 48 hours of implantation. Low, medium Chitosan showed high hemoglobin contents, medium and high Chitosan showed high hematocrit value after 48 hours of implantation. As a result, medium, high-Chitosan induced potential incompatibility in the tissue after 48 hours, but there was little effects to the skin inflammation. The values of biodegradable films, which prepared from natural polymers measured in this study were some satisfiable results at short period with those of ideal skin bioimplants and artificial skin.

A study was conducted to observe the effects of dexamethasone sodium 21 phosphate injection in different amounts, intervals and times on the fluctuation of the parasitized erythrocytes in the peripheral blood of the T. sergenti carrier calves. A total of 31 calves including 15 Holstein and 16 Korean native male calves aged 6-12 months (125-300kg) was used. Results observed were as follows. 1. The calves injected 0.2mg/kg body weight two and three times in 48 hour intervals and 5 times in 24 hour intervals observed that 2 out of 2 heads, 3 out of 6 heads, and 4 out of 5 heads, respectively were substantially increased parasitized erythrocytes in the blood for 3-11 days after the first injection and continued to 2-10 days. 2. However, the calves injected once with 0.1mg/kg body weight and all control calves showed no visible change of the parasitized erythrocytes in the blood during the experimental period. 3. The animals injected over 2 times with 0.2mg/kg body weight tended to be decreased the number of erythrocytes, hemoglobin concentration and PCV for 2-3 days after first injection and continued about one week. 4. All animals injected the dexamethasone were observed the neutrophilic leukocytosis, eosinopenea and lymphopenea until 48 hours after injection.

The objective of this study was (a) to examine the change of bloodchemistry and (b) to investigate the secretion trend of endocrinological substance in a dog model after laser-beam radiation at different level of frequency (250 Hz, 2,000 Hz, 5,000 Hz and 8,000 Hz). The experimental groups were divided into four groups were divided into four groups on the basis of the level of frequency radiated and stimulated for five minutes. Before stimulation and after a lapse of time (10-minute, 30-minute and 60-minute) all dogs were checked the following parameters; cortisol, ACTH, RBC, hemoglobin, hematocrit, WBC, Ca, P, ALT, AST and creatinine. The results were as follow: ten minutes after stimulation, cortisol level of 250 Hz group, 2,000 Hz group, 5,000 Hz group and 8,000 Hz group was increased 18.8%, 20.5%, 23.2% and 309%, respectively. Ten minutes after stimulation, ACTH level of 250 Hz group, 2,000 Hz group, 5,000 Hz group and 8,000 Hz group was increased 26.7%, 26.6%, 30.5% and 29.5%, respectively. It began to decrease and at 30-minute after stimulation resturned to pre-stimulation level at 60-minute after stimulation. In blood examination RBC, hemaoglobin, hematocrit and WBC level showed slight increase and decrease and returned to pre-stimulation level at 60-minute after radiation. In bloodchemical examination serum calcium, inorganic phosphorus, ALT, AST and creatinine level were within normal physiological ranges.

The retention behavior of proteins was investigated by using reversed-phase chromatography (RPC), comparing to the retention behavior of small molecules in RPC. The evaluation was carried out on a SynChropak RP-P($C_{18}$) column with 0.1% aq. TFA-organic solvent modifier such as acetonitrile, isopropanol, and ethanol. The Z value (the number of solvent molecules required to displace the solute from the surface) was a general index for the characterization of protein retention as a function of organic concentration over a range of temperature between 5 and 70$^{\circ}C$. Van't Hoff plots provided the basis for evaluating the enthalpic and entropic changes associated with the interaction between protein and the stationary phase. Z values did not change significantly at the range of temperature showing the consistent ${\Delta}H^{\circ}$ and ${\Delta}S^{\circ}$ values. From these investigation, it was concluded that the retention behavior of proteins in RPC was able to be predicted by the retention parameters applied to small molecules. Furthermore, myoglobin and hemoglobin in RPC as stated above showed a similar retention behavior regardless of their molecular weights.

The study investigated the changes in growth performance, hematological parameters, plasma components, and stress indicators of juvenile starry flounder, Platichthys stellatus, depending on varying exposure to hexavalent chromium. P. stellatus was exposed to waterborne chromium at 0, 50, 100, 200, and 400 ppb for 4 weeks. The result showed that Cr exposure resulted in decreased daily length gain (DLG), daily weight gain (DWG), condition factor (CF), and hepatosomatic index (HIS) in P. stellatus. In terms of hematological parameters, red blood cell (RBC) count, hematocrit (Ht), and hemoglobin (Hb) significantly decreased at 400 ppb after 2 weeks. In terms of plasma components, inorganic analysis was unchanged and cholesterol, an organic component, considerably increased at 400 ppb after 4 weeks. Plasma enzyme components including glutamic oxalate transaminase (GOT) and glutamic pyruvate transaminase (GPT) were significantly increased. Stress indicators such as cortisol and glucose were notably increased over 100 ppb after 4 weeks with increasing chromium concentration. The results indicate that exposure to waterborne Cr induced toxic effects on growth, hematological parameters, plasma components, and stress indicators.

Rosiglitazone is a thiazolidinedione-class antidiabetic drug that reduces blood glucose and glycated hemoglobin levels. We here investigated the interaction of rosiglitazone with Kv3.1 expressed in Chinese hamster ovary cells using the wholecell patch-clamp technique. Rosiglitazone rapidly and reversibly inhibited Kv3.1 currents in a concentration-dependent manner (IC₅₀ = 29.8 µM) and accelerated the decay of Kv3.1 currents without modifying the activation kinetics. The rosiglitazonemediated inhibition of Kv3.1 channels increased steeply in a sigmoidal pattern over the voltage range of -20 to +30 mV, whereas it was voltage-independent in the voltage range above +30 mV, where the channels were fully activated. The deactivation of Kv3.1 current, measured along with tail currents, was also slowed by the drug. In addition, the steady-state inactivation curve of Kv3.1 by rosiglitazone shifts to a negative potential without significant change in the slope value. All the results with the use dependence of the rosiglitazone-mediated blockade suggest that rosiglitazone acts on Kv3.1 channels as an open channel blocker.
