Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation that is not fully reversible. COPD has systemic effects, such as skeletal muscle dysfunction and abnormal weight loss. It also has been suggested that COPD is related to other chronic disease, such as cardiovascular disease, osteoporosis, and anemia. The aim of this study was to evaluate a symptom questionnaire and laboratory findings in subjects with air flow limitation. Methods: We evaluated a symptom questionnaire and laboratory findings in subjects with airflow limitation detected by spirometry in conjunction with the Second Korean National Health and Nutrition Examination Survey. A total of 9,243 adults over the age of 18 were recruited. Among the adults, we finally analyzed 2,217 subjects who met the acceptability and repeatability criteria of spirometry, showed normal findings on chest radiography, and were older than 40 years of age. Results: There were 288 subjects with airflow limitation as determined by spirometry. The frequency of respiratory symptoms such as cough, sputum and wheezing were significantly higher in subjects with airflow limitation (p <0.01). Hemoglobin and hematocrit levels were higher in subjects with airflow limitation (hemoglobin level 13.98 mg/dL vs. 13.62 mg/dL, hematocrit 42.10% vs. 40.89%; p<0.01). The HDL cholesterol level was lower in subjects with airflow limitation (44.95 mg/dL vs. 45.60 mg/dL; p<0.01). There was no significant difference in the total cholesterol, triglyceride, blood urea nitrogen, creatinine, and fasting glucose levels. Conclusion: In subjects with airflow limitation, prevalence of respiratory symptoms was higher than in normal spirometry subjects and the levels of hemoglobin and the hematocrit were higher. The HDL cholesterol level was lower in subjects with airflow limitation.
Slow-release fertilizers (SRF) have been used to reduce nutrient loss through increasing fertilizer efficiency and to save labor. Several SRFs were developed for rice plant in Korea, but there is few for horticultural crop plants. Two slow-release complex fertilizers, 100T and 150T, which made for controlling nitrogen release time up to 100 and 150 days, respectively, were selected for the incubation test cto evaluate nitrogen (N) release rate in soil. The N of urea selected as the control was completely released within a week after application. Sixty three and 53% of total N were released from 110T and 150T of slow release fertilizers within 8th weeks after application, respectively. For pepper cultivation CF110 and CF150, new slow-release complex fertilizer, were made of mixing 40% of conventional fertilizer and 60% of 110T and 150T, respectively, based on the amount of recommended fertilizer for pepper cultivation $(N-P_2O_5-K_2O=190-112-149\;kg\;ha^{-1})$, and were totally applied before pepper transplanting in the field as the basal fertilizer. Inorganic N $(NH_4^+-N+NO_3^--N)$ concentration in soil was higher in the CF110 treatment than in the control (NPK) at all period of pepper cultivation. In the CF150 treatment concentration of inorganic N in soil was low compared to control up to 8th weeks after transplanting. However, there was no difference in plant height and nutrient content of pepper leave between CF110 treatment and the control. In comparison, plant height was significantly lower in CF150 than the control and CF110 treatments. Around 4% of fresh pepper yield was increased in CF110 compared to the control, but it was decreased to about 2% by CF150 treatment. Conclusively, CF110 form could be recommended as a slow release fertilizer for pepper cultivation.

This study was conducted to comparatively assess quantitative indicating factor for biomineralization characterizing $CO_2$ mineralization on three type of minerals (i.e., $CaCl_2$, $MgCl_2$, $CaCl_2-MgCl_2$) in an aqueous solution amended with Bacillus pasteurii or indigenous microorganisms for a S landfill cover soil. For given three types of minerals, $NH_4{^+}$ (urease activity) was released at the highest of 88 mg/L for $MgCl_2$, then 85 mg/L for $CaCl_2$, and the lowest of 42 mg/L for $CaCl_2-MgCl_2$. $CO_2$ gas in the head space was completely removed after 12, 12, and 24 hr for $CaCl_2$, $MgCl_2$ and $CaCl_2-MgCl_2$, respectively. $Ca^{2+}$ concentration in $CaCl_2$ solution was the quickest and the greatest decreased 92% for 12 hr whereas that in $CaCl_2-MgCl_2$ solution was lower at 85% for 36 hr. $Mg^{2+}$ concentration in $MgCl_2$ was more efficiently decreased at 46% for 48 hr than that of $CaCl_2-MgCl_2$ solution of 38.5% for 72 hr. Regardless of types of minerals or their concentration, pH was changed from 5.5 to 9 by biomineralization being progressed. Microbial activity ($OD_{600}$) was also changed from 0 to 0.6. SEM images indicated that spheroidal and trapezoid shape crystal were formed, which were identified as of $CaCO_3$ (Calcite) and $MgCO_3$ (Magnesite) by X-ray diffraction. In the long run, $NH_4{^+}$ (urease activity), $CO_2$ gas, $OD_{600}$, pH, $Ca^{2+}$ and $Mg^{2+}$ would be suitable for reasonable indicating factor in order to assess the degree of biomineralization efficiency.
The characteristics of the three alkaline proteinases, Enz. A, B and C, from the pyloric caeca of mackerel have been investigated. The optimum condition for the activity of the Enz. A, B and C was pH 9.4, 9.8 and 9.8 at $45^{\circ}C$ for $2\%$ casein solution, and was pH 9.2 10.2 and 9.8 at $45^{\circ}C$ for $5\%$ hemoglobin denatured by urea, respectively. Enz. A, B and C by heat treatment at $50^{\circ}C$ for 5 min were inactivated 90, 33 and $37\%$, respectively, over the original activity. The reaction rate of the three alkaline proteinases was constant to the reaction time to 40 min in the reaction condition of $2{\mu}g/ml$ of enzyme concentration and $2\%$ casein solution. The reaction rate equation and Km value against casein substrate determined by the method of Lineweaver and Burk were: Enz. A, Y=3.6X and $Km=5.0{\times}10^{-3}\%$; Enz. B, Y=6.0X and $Km=1.0{\times}10^{-3}\%$; Enz. C, Y=4.2X and $Km=3.6{\times}10^{-3}\%$. The three alkaline proteinases were inactivated by $Ag^+$ and $Hg^{2+}$, but activated by $Mn^{2+},\;Sn^{2+}\;and\;Pb^{2+}$, Enz. B and C were remarkably inhibited by the soybean trypsin inhibitor. Molecular weight of Enz. A, B and C determined by SDS-polyacrylamide gel electrophoresis and Sephadex G-100 gel filtration was in the range of $27,500{\pm}2,500,\;20,500{\pm}1,500\;and\;15,250{\pm}250$, respectively.

In the present work antidotal effect of dietary garlic was studied on lead-intoxicated rat. One of 5 groups of young Wistar sp. male rat, aged 4 weeks for control were fed only normal diet. Lead (25 ㎎/㎏.bw/week) was administered to other four groups for plumbism model over 4 weeks, of which three groups were supplemented with one of the following raw garlic juice: 1.10 (1% diet), 2.21 (2%) and 3.31 (3%) ㎎/㎏.bw/day respectively. Body weight gain rates in all garlic group significantly increased, especially in 2% garlic group that showed 9.8% net gain, as compared with only-lead treated group but lower values than control. The fecal and urinary lead excretion in all garlic groups significantly increased in a dose dependent fashion with highest value of 9.59% net gain in 3% garlic group as compared to lead treated control group. In comparison with lead treated control group, all garlic groups showed significantly increased hemoglobin contents, hematocrit values (Hct), red blood cell (RBC) count, mean corpuscular volume (MCV), and δ-amino levulinic acid dehydratase (δ-ALAD) activities. The values of 2% and 3% garlic groups remarkably increased while no significant difference between the values of 2% and 3% garlic groups was observed. The ALT activities, blood urea nitrogen (BUN) and creatinine (CR) in all garlic groups significantly decreased as compared with lead-treated control group. The values of 2% garlic group were the lowest and significantly different from the values of 1% and 3% garlic groups. The results showed that 2%-3% garlic juice in diet had obviously antidotal effects in lead-poisoned rats by promoting lead excretion. However, mega dose garlic such as in 3% garlic group might have some adverse effects on hepatic and renal functions in rats. In conclusion, the dietary habit to take ordinary garlic sauce in appropriate amount, may be helpful for preventing lead or other heavy metal intoxication.

The effect of different inoculation amounts of Pisolithus tinctorius (Pt) spores and fertilizers on the growth of Pinus densiflora seedlings grown in fumigated or nonfumigated soils were tested in the: polyethylene pots. To infest the pot soil with Pt spores, the mixture of the spores with sterilized nursery soil was used after seeding. Eighteen months after inoculation, mycorrhizal formation was 42-70% in fumigated plus Korean-Pt inoculated pots, 60-70% in fumigated plus U.S.-Pt inoculated pots, and less than 1% in non-fumigated, Korean-Pt inoculated pots. Growth enhancement effect of Pt spore inoculation was shown on only fumigated soil and the inoculation increased the seedlings height (8-38%), stem diameter (9-40%) and dry weight (6-73%). Especially 0.4g per pot application rate increased the height (30-31%), stem diameter (23-28%) and dry weight (56-69%), while the 0.2g U.S. Pt spore per pot rate increased 26-38, 17-20 and 58-60%, for height, stem diameter, and dry weight respectively. At 1X fertilizer application rate (urea 2g, fused superphoshate 4g, and potassium chloride 1g per pot), the 0.4g per pot rate resulted in more dry weight by 18% than that at 1/2X rate. The result indicated that there is a need for further research on inoculating nonfumigated soil with Pt and that appropriate application rates of fertilizers and Pt spores are 1X and 0.2-0.4g per pot on fumigated soil, respectively.

The purpose of this study was to compare knowledge on hypertension and blood parameters through blood pressure control of hypertensive patients commuting to a public health center. Hypertensive subjects were classified according to their blood pressures into a well-controlled group (SBP<140 mmHg and DBP<90 mmHg, n=44) and an uncontrolled group ($SBP\geq140mmHg\;or\;DBP\geq90mmHg$, n=41). All subjects were interviewed for clinical characteristics, effort for health maintenance and knowledge on hypertension and nutrition. Biochemical measurement of blood urea nitrogen, creatinine, triglyceride, total cholesterol, HDL-cholesterol and fasting blood glucose (FBG) were obtained from subjects. The knowledge about hypertension and effort for health maintenance were not significantly different between the groups. However, the nutrition knowledge score of the well-controlled group was significantly higher (p<0.05) than that of the uncontrolled group. On the test of nutrition knowledge, 97.7% of the well-controlled group answered correctly to the item, 'Medication is an easy way to control blood pressure'. This result was significantly higher (p<0.05) than that of the uncontrolled group of whom 82.9% answered correctly. Participants in both groups had only a little understanding about the importance of a balanced diet. Blood parameters were in the normal range and there was not a significant difference between the groups. However total cholesterol, triglyceride and fasting blood glucose levels of the uncontrolled group were higher than those of the well-controlled group. Therefore, education programs about the continuous control of hypertension through careful monitoring, medication, and exercise are required. The uncontrolled group was especially in need of strengthening education. Also more effective nutrition education programs about low salt, high fiber, low cholesterol, and balanced diets are required for hypertensive patients commuting to public health center.

It is inevitable to use germicidal agents like parabens, imidazolidinyl urea, phenoxyethanol and chlorphenesin to preserve the cosmetics. Although effective in reducing microblological contamination, chemical preservatives are irritative, allergenic and even toxic to human skin. So it is needed to decrease or eliminate usage of preservatives in cosmetic products Glycerin, butylene glycol (BG), prorylene glycol (PG), and dipropylene glycol (DPG) are widely used in cosmetics as skin conditioning agent or solvents. At high concentrations, they have antimicrobial activities, but deteriorate product quality like sensory feeling or safety. The purpose of study is to evaluate the effects of polyols on antimicrobial and preservative efficacy and confirm whether using adjusted polyols can decrease the contents of preservatives without deterioration of the quality of cosmetics. Effects of common polyols on antimicrobial activities of general preservatives were measured. BG and PG significantly (p < 0.05) increased activities of preservatives, but glycerin influenced little. It was inferred from the regression analysis of the results with S. aureus that adding 1% of PG increased activities of preservatives up to $2.1{\sim}8.4 %$ and BG improved activities of preservatives up to $1.8{\sim}8.4 %$. The challenge test results for oil in water lotions and creams showed that BG and PG improved the efficacy of preservative systems up to 40 % at a range of $5.5{\sim}9.9 %$, but glycerin had little effect on it. The measured rates of improvement were analogous to the inferences from regression analysis. It can be concluded that is possible to reduce total chemical preservatives up to 40 %, consequently improve the safety and sensory quality of cosmetics with the precision control of polyols. Added to that, using this paradigm, low preservative contents, praraben-free system, and even preservative-free systems can be expected in the near future.

To investigate the effect of Pinus densiflora on biochemical parameters in type I diabetic rats, we evaluated the changes of body weight, fasting blood glucose level, oral glucose tolerance test (OGTT) and biochemical parameters after the intraperitoneal injection of distilled solution of Pinus densiflora in streptozotocin (STZ)induced rats. Thirty-seven male Sprague Dawley rats $(180\pm10g)$ were divided into four groups; diabetic mellitus (DM) group received STZ (50 mg/kg BW, i.v.); low level of pine extract (LP) group received Pinus densiflora (5 mg/kg BW, i.p.), high level of pine extract (HP) group received Pinus densiflora (10 mg/kg BW, i.p.) after the single injection of STZ (50 mg/kg BW, i.v.), respectively. Normal control (NC) group received saline. The change of fasting blood glucose level and OGTT were measured using glucocard II, and the change of biochemical parameter were measured by Automatic Chemistry Analyzer (Hitach-747, Japan). Mean body weight change of DM group was retarded greatly by STZ-exposure. While, body weights of LP and HP groups were progressively increased with some fluctuation, although the increase rates were slower than that of NC group. Fasting blood glucose levels of LP and HP groups were reduced by Pinus densiflora injection, although the fasting blood glucose levels were higher than that of NC group. The results of OGTT was significantly improved in both of LP and HP group compared to DM group. Increases of blood glucose, alanine aminotransferase (ALT), alkaline phosphatase (ALP) and blood urea nitrogen (BUN) levels by STZ-exposure were attenuated by the Pinus densiflora treatment (p<0.05). From the results, it was suggested that Pinus densiflora has a tendency to decrease STZ-induced toxicity in terms of monitoring fasting blood glucose, OGTT and some biochemical parameters of rat.
