The purpose of this study was to compare the nutrient intakes, blood pressure, and biochemical values and lipid profile in blood according to smoking status. Subjects were recruited from Korean adult men, which included non-smoker (n=47), smoker (n=58), and ex- smoker (n=44) . Anthropometrical measurement, blood pressure measurement, dietary intake assessment using 24-hour recall method, and blood collection and analysis were conducted. The average age, height, weight, and BMI of the subject were 54.7 years, 165.8 cm, 67.3 kg, and $24.5\;kg/m^2 $, respectively. There was no significant difference in general characteristics among three groups. The mean daily intakes of energy and protein were 1740.9 kcal and 69.6 g. The daily folate intake of the smoker was significantly lower than that of the non- smoker or ex-smoker. However, cholesterol intake of the smoker was significantly higher than two groups. The daily total food intake was 1250.0 g for non-smoker, 1180.1 g for smoker, and 1237.5 g for ex-smoker. The mushrooms intake in the smoker was significantly lower than that in the ex - smoker. However, eggs intake of the smoker was significantly higher than two groups. The RBC count and serum GOT/GPT of the subjects were $4598.2\times1000/mm^3$ and 27.3/27.3 U/L. The WBC count, hematocrit and hemoglobin of the smoker were significantly higher than those of the non-smoker and ex-smoker. Blood pressure and serum lipids of the subjects were 128.3/75.5 mmHg for SBP/DBP, 180.2 mg/dL for total cholesterol, 160.8 mg/dL for triglyceride, 41.5 mg/dL for HDL-cholesterol, 106.5 mg/dL for LDL-cholesterol, and 3.5 for atherogenic index. Especially serum triglyceride of smoker was significantly higher than that of non-smoker. The above results revealed that some nutrient intakes, such as folate and cholesterol, and hematological findings, and serum triglyceride of the smoker were different from non-smoker. However, these differences were recovered to non-smoking status by prohibition of smoking. Therefore, in order to stop smoking, the effect of smoking on nutritional and health status should be informed to smoker and more systematic study should be conducted.

To investigate the anti-thrombotic activities of the lotus (Nelumbo nucifera Gaertner), various hot-water extracts were prepared from the leaf, pod of seed (PS), seed, embryo of seed (ES), root, and the node of root (NR) of the lotus. The highest extraction ratio was found in the NR (20.3%), followed by the seed, root, leaf, ES, and PS. These extracts had pH and acidity levels ranging from 5.6~6.5 and 0.06~0.20%, respectively. The seed extract showed 70% brix, whereas the leaf and PS extracts showed less than 0.1% brix. The highest contents of total polyphenol (179.7 mg/g), total flavonoids (161.4 mg/g), and reducing sugar (161.4 mg/g) were observed in the leaf extract, and the highest total sugar content (873.0 mg/g) in the seed extract. Anti-coagulation assay of the extracts of NR, leaf, and PS showed strong activities. In particular, at a concentration of 5 mg/ml, the PS extract had 15-fold extended thrombin, prothrombin, and activated partial thromboplastin times. However, only the ES extract showed activities inhibitory to platelet aggregation, with treatment with 0.25 mg/ml of ES extract decreasing platelet aggregation to 25.1%, a reduction comparable to that effected by aspirin. The extracts other than the seed extract showed no hemolysis activities against human RBC at treatments of up to 1 mg/ml. These results suggest that the NR, PS, seed, and ES, all byproducts of the lotus agriculture industry, have high potential as novel sources of anti-thrombotic agent.
