$\beta$-glucan is a fiber-type complex sugar (polysaccharide) derived from the cell wall of baker's yeast, oat and barley fiber, and many medicinal mushrooms, such as maitake. The primary uses of $\beta$-glucan are to enhance the immune system, to lower blood cholesterol levels and to treat tumor. $\beta$-glucan has no systemic toxicity in mice, therefore it needed clinical trail to prove efficacy and safety for human. The subjects total 56 healty volunteers were divided into two groups including taken $\beta$-glucan tablet group and placebo group. Subjects were taken two tablets per oral for 4 weeks. They had agreed to take part in this experiment, and didn't take any other clinical trail products. After 4 weeks blood of subjects were checked. The check list are TNF-$\alpha$, INF-$\gamma$, IL-2, IL-4, total WBC, differential WBC, RBC, hemoglobin, platelet, MCV, MCH, MCHC, HCT, Na, K, Ca, Cl, AST, ALT, ALP, $\gamma$-GTP, total protein, triglyceride, total cholesterol, total bilirubin, albumin, uric acid, creatinine, BUN, pH, protein, glucose, ketone body, blood, bilirubin. We evaluated efficacy by cytokines that compare before and after taking. Collected data were analyzed as two sample t-test, chi-square test and ANOVA using SAS V.9.1.This study results are that in TNF-$\alpha$ of $1^{st}$ efficacy measurement item, all of two groups figure were increased significantly compare to before figure. In IL4 of $2^{nd}$ efficacy measurement item, experimental group figure were decreased significantly but placebo group figure were increased. The conclusions show that based on the above results, $\beta$-glucan has favorable effect to enhance immune system, especially IL4 results showed that it has effect to improve the allergic immune system.

Intracellular calcium concentration ($[Ca^{2+}]_i$) may play a crucial role in a variety of neuronal functions. Here we report that in primary culture of mouse cerebellar granule cells nicotinic acetylcholine receptors (nAChRs) are expressed in a specific developmental stage and involved in the regulation of intracellular calcium homeostasis. Nicotine-mediated calcium responses were measured using $^{45}Ca^{2+}$ or fluorometrically using the calcium-sensitive fluorescent dye fura-2. Maximal uptake of $^{45}Ca^{2+}$ evoked by nicotine in mouse cerebellar granule cells were revealed $8{\sim}12$ days in culture. In contrast, nicotine did not alter the basal $^{45}Ca^{2+}$ uptake in cultured glial cells. In cerebellar granule cells nicotine-evoked $^{45}Ca^{2+}$ uptake was largely blocked by the NMDA receptor antagonists. Glutamate pyruvate transaminase (GPT). which removes endogenous glutamate, also prevented nicotine effects, implying the indirect involvement of glutamate in nicotine-mediated calcium responses. Fluorometric studies using fura-2 showed two phases of nicotine-evoked $[Ca^{2+}]_i$ rises: the initial rising phase and the later plateau phase. Interestingly, the NMDA receptor antagonists and GPT appeared to inhibit only the later plateau phase of nicotine-evoked $[Ca^{2+}]_i$ rises. The present results imply that nicotine mediated $^{45}Ca^{2+}$ uptake and $[Ca^{2+}]_i$ rises are attributed to the calcium fluxes through both nAchRs and NMDA receptors in a time-dependent manner. Consequently, nAChRs may play an important role in neuronal development by being expressed in a specific developmental stage and regulating the intracellular calcium homeostasis.

Coronary artery calcium scores(CACS) has been used as surrogate marker for coronary atherosclerosis. We evaluated 1042 patients who visited the Department of Health Promotion Center in Chonnam National University Hospital and had a test of the CACS from January 2006, to December 2008. This study was performed to evaluate the relation of the CACS with Cadiovascular disease(CVD) risk factors and FRS. CACS and FRS was a significant difference between the group whose calcium score was 0 and the group whose calcium scores were 1 in case of men 2.38(95% CI, 1.83-3.11), women 2.12(95% CI, 1.03-4.35). The age-and sex-adjusted odds ratios for predictor of CVD risk factors to women with age was 1.10(95% CI, 1.06-1.15), HDL-cholesterol was 2.38(95% CI, 1.04-5.44), Fasting plasma glucose was 2.89(95% CI, 1.16-7.21), to men with age was 1.11(95% CI, 1.08-1.14), LDL-cholesterol was 2.12(95% CI, 1.28-3.50), gamma-GTP was 1.73(95% CI, 1.17-2.55), Diabetes mellitus medication was 3.92(95% CI, 1.73-8.89). The CACS seems to be a siginificant factor to evaluate the CVD risk factors.

The present study was designed to investigate i) the action of various nucleotides on membrane permeability of rat red blood cell and hepatocyte for $Na^{+}$ and $Rb^{+}$ ii) the characteristics of purinoceptors on these cell membranes. Blood from Sprague-Dawley rats was obtained by carotid arterial cannulation. Red blood cells were then washed 3 times with saline at $4{\circ}C$. Hepatic parenchymal cells were isolated from rat livers by using a modification of the Berry and Friend (1969) method. For the $Na^{+}$ influx studies, isolated RBC and hepatocyte were incubated in incubation medium containing $^{22}Na^{+}0.2\;{\mu}Ci/ml$ at $37^{\circ}C$. After various time intervals samples were removed from the incubation flask and washed out 3 times with ice-cold washing solutions. Cells were destroyed by adding Triton X-100 and TCA solution. After centrifugation, the supernatants were assayed for $^{22}Na^{+}$ by gamma counter. $^{86}Rb^{+}$ was used to simulate $K^{+}$ in these $K^{+}efflux$ studies. Isolated hepatocytes were incubated for 60 min in the loading solution containing $^{86}Rb^{+}\;10\;{\mu}Ci/ml$ at $37^{\circ}C$. After loading, the cells washed out 3 times by centrifugation with washing solution. The cells were incubated in buffer solution at $37^{\circ}C$. At intervals thereafter, samples were removed and centrifuged. The supernatants were analyzed for $^{86}Rb^{+}$ by liquid scintillation counter. The main results of the experiments were: 1) ATP and ATPP increased in both $^{22}Na^{+}$ influx and $^{86}Rb^{+}$ efflux in the red blood cell. Although ADP showed a tendency to increase in RBC membrane permeability for $^{22}Na^{+}$ and $^{86}Rb^{+}$, the changes were not significantly different from the control. 2) The Significant changes in $^{22}Na^{+}$ and $^{86}Rb^{+}$ flux by ATP were also demonstrated in hepatocyte. ATPP and ADP showed a tendency to increase in hepatocyte membrane permeability for both ions. 3) Other nucleoside triphosphates-ITP, GTP and CTP-did not change in membrane permeability for $^{22}Na^{+}$ and $^{86}Rb^{+}$ in RBC and hepatocyte. In conclusion, not only ATP but also ATPP activate purinoceptors and change in membrane permeability for $Na^{+}$ and $K^{+}$. In order to activate purinoceptors on the cell membrane, the nucleotides have to possess intact adenine moiety and three phosphates or more in its molecule.

The aim of this study was 1) to confirm the practical efficiency of a routine milk P4 monitoring system for postpartum reproductive management of a dairy herd, and 2) to evaluate the relationship between the blood metabolic profiles, milk quality and body weight of individual cows in the farm records, which may reflect the postpartum nutritional condition, and the time of postpartum resumption of ovarian activity of dairy cows. A total of 116 Holstein cows was used in the present study. First, during the period of Experiment 1, postpartum reproductive management based on weekly measured milk P4 concentration from individual cows was conducted. Compared with the reproductive records of the past two years without P4 monitoring, although the day from calving to first AI did not change, both the number of AI until pregnant (with P4; 1.9 times vs. without P4; 2.9 times) and the days open (with P4; 95.1 days vs. without P4; 135.8 days and 133.8 days) were significantly decreased. In Experiment 2, the measurement of blood constituents such as albumin, blood urea nitrogen, packed cell volume, ammonia, glucose, total cholesterol, non-esterified, AST and $\gamma$-GTP was performed on the blood samples taken once approximately 14 days postpartum, to monitor both health and nutritional conditions. The milk constituent parameters, such as milk protein (MP), milk fat (MF), SNF and lactose, collected from the monthly progeny test of individual cows, were used to monitor the postpartum nutritional status. Furthermore, the data obtained from the routine measurements of body weight were used to calculate the rate of peripartum body weight loss. The resumption day of the postpartum estrous cycle was assumed from the milk P4 profiles of individual cows. There was no clear relationship between each parameter from blood examination and those from resumption time. However, the cows had low values of MP, and SNF, which significantly affected the resumption of the postpartum estrous cycle. Similarly, a higher rate of body weight loss indicated a significant delay (more than 1 month) in the resumption of the postpartum estrous cycle, compared with the groups that had a medium or lower rate of body weight loss. The results of the present study demonstrated that the implementation of routine milk P4 monitoring-based postpartum reproductive management, together with milk quality parameters and routine BW data available in field conditions may be utilized as a practical approach for increasing the postpartum reproductive efficiency of a high yielding dairy herd.

We investigated the anti-obesity effects of Ishige okamurae extract (IOE) on body weight, epididymal adipose tissue weight, plasma lipid levels, and leptin levels in high-fat diet (HFD)-induced obese mice. After inducing obesity by feeding 45% HFD for 4 weeks, C57BL/6J mice were randomly assigned to HFD or HFD containing 5% IOE, and then fed for 6 weeks. The body weight and epididymal adipose tissue weight were increased by HFD, but they were significantly less in animals fed HFD containing 5% IOE than in those fed HFD. Levels of plasma triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in animals fed HFD containing 5% IOE compared with the HFD group. The plasma leptin level was significantly lower in animals fed HFD containing 5% IOE. The diet containing 5% IOE did not show any adverse effects on liver and kidney functions. These results suggest that IOE has a potential as anti-obesity agent by reducing body weight and lowering the levels of obesity-related factors in plasma.

This study investigated the properties of primary cultured proximal tubule cells in hormonally defined(insulin, transferrin, and hydrocortisone), serum-free medium or 10% serum-supplemented medium. The growth rate of the primary cultured proximal tubule cells was lower in the hormonally defined, serum-free medium than in the 10% serum- supplemented medium(p < 0.05), while the activities of brush border marker enzymes, alkaline phosphatase(AP), leucine aminopeptidase(LAP), and y-glutamyl transpeptidase(${\gamma}$-GTP) were increased(p < 0.05). The activities of these enzymes, however, decreased with the lapse of incubation time to 50-70% after 6 days culture compared to those of the freshly-prepared proximal tubules. The enzymatic activities of the primary cultured proximal tubul cells on 6, 9, 12, and 15 days of culture were significantly increased in the hormonally defined, serum-free medium compared to the 10% serum-supplemented medium(p < 0.05). The functional differentiation of the primary culture was examined by observing multicellular domes of the confluent monolayer, which is indicative of transepithelial solute transport. The dome formation by the proximal tubule cultures occurred at a higher frequency in the hormonally defined, serum-free medium than in the 10% serum-supplemented medium(p < 0.05). Upon electron microscopic examination, an increased density of the brush border was observed in the hormonally defined, serum-free medium compared to the cells grown in 10% serum-supplemented medium. The activities of $Na^+$glucose cotransporter($^{14}C$-a-MG uptake), $Na^+$phosphate cotransportere($^{32}P$ uptake) and $Na^+$ transporter($^{22}Na^+$ uptake) in the brush border membrane, and of $Na^+/K^+$-ATPase($^{86}Rb$ uptake) in the basolateral membrane were significantly stimulated in the hormonally defined, serum-free medium than in 10% serum-supplemented medium(p < 0.05). In conclusion, the primary cultured proximal tubule cells grown in the hormonally defined, serum-free medium demonstrated a slower growth rate, but the functions of cell were enhanced.

The effects of dietary eggs on liver and serum lipids, serum protein and mineral concentrations, and enzyme activities in male rats were studied. Sprague-Dawley rats were fed four types of diets for 4 weeks, respectively: a control diet, a control diet supplemented with 5, 10 or 15% eggs powder. In rats fed 5, 10 or 15% egg diets the body weight gain, the food intake, the weights of kidney and epididymal fat pad were similar to those in rats fed the control diet. The hepatic weight, hepatic cholesterol and triglyceride concentrations of rats fed the all egg diets were significantly higher than those of rats fed the control diet. The concentrations of total cholesterol, HDL-cholesterol, LDL+VLDL-cholesterol, triglyceride and phospholipid in the serum of rats fed the all egg diets were similar to those of rats fed the control diet. In the rats fed 5% egg diet the HDL-cholesterol/total-cholesterol ratios was significantly increased, and the atherogenic index was significantly decreased compared with those in the rats fed 10 or 15% egg diets. The serum total protein and albumin concentrations of rats fed 10 or 15% egg diets were significantly increased compared with those of rats fed the control diet. The serum calcium levels of rats fed the all egg diets were significantly increased compared with those of rats fed the control diet. No differences were noted in the concentrations of urea nitrogen, creatinine, glucose and hemoglobin, and activities of GOT, GPT, ${\gamma}-GTP$ and alkaline phosphatase in the serum among the rats with on all the experimental diets. These results showed that the all egg diets feeding increased cholesterol and triglyceride concentrations in liver, but no differences lipids and lipoprotein cholesterol concentrations in serum of rats.

The purpose of this study was to investigate the effect of Bojungikgitang(補中益氣湯), Soeumin bojungikgitang(少陰人 補中益氣湯) and its component groups on diabetes in alloxan induced diabetic rats. Sprague-Dawley male rats weighing $200{\pm}10\;gm$ were randomly assigned to one normal, one control and five experimental groups. The experimental groups was classified into to Bojungikgitang(B1 group), Soeumin bojungikgitang(B2 group), Bogihyulyak(B0 group), Siho-sengma(B1+ group) and Gwakhyang- soyeup(B2+ group). Diabetes was experimentally induced by abdomenal injection of 100 mg/kg of body weight of alloxan. Animals were sacrificed at the 6th day and 11th day of diabetic states. The results were obtained as follows: In carbohydrate metabolism, the level of glucose in control group was three-fold higher after alloxan injection than that of normal group. In B1, B2 groups the level of glucose was decreased by 39% and 43% compared with that of control group, and in component groups it was decreased by 73%, 81%, and 80% respectively. In fat metabolism, the level of triglyceride and total cholesterol in serum were lower in B1 and B2 groups with high significant difference and had similar tendency in components groups compared with that of control group. The level of HDL cholesterol on serum were increased in B1 and B2 group with significant difference. And in component group it had similar tendency compared with that of control group. In protein metabolism, the level of total protein and albumin were higher in B1 and B2 group with significant difference, and in component group also increased but with no significancy compared with control group. In kidney function, the level of creatinine group with significant difference, and other compared with control group. In liver function, the level of GOT, GPT, ${\gamma}$-GTP. ALP and bilirubin were lower in B1 and B2 group with significant difference, and in component had similar tendency compared with control group. But in the level of LDH, it was decreased with no significancy. These results indicate that Bojungikgitang(補中益氣湯), Soeumin bojungikgitang(少陰人 補中益氣湯) has strong effect on diabetes and it is useful to prevent diabetes, and in component groups the difference between B1+ and B2+ group was not significant.
