Objective : Chu Cheng(褚澄) was known as the author of Zayaofang(雜藥方) and Chushiyishu(褚氏遺書). His mentions in the medicine have been sufficiently told in his posterity. However, there have been no studies on Chu Cheng and his work like Chushiyishu in Korea. Here, I seek to investigate Chu Cheng and his ideas in the medicine. Method : I investigate Chushiyishu, known as written by Chu Cheng and his scattered portions. Result & Conclusion : His nom de plume(字) is Yandao(彦道). It was supposed that he was born before the year of 420, the era of Dong Jin(東晉) and died in 483. He wrote Zayaofang and Chushiyishu. However, the former was lost. The latter consists of 10 pieces of medical theories. The contents carved on the stone plate was discovered for the first time before 934 at a place presumed as his grave. Then, it was stored as the inner and outer coffins in the tomb of Xiao Guang(蕭廣) in 935 and written on the paper by Buddhist monk Shi Yikan(釋義堪) in 1127. Then, Liu Jixian(劉繼先) carved on the wood for publication and finally, the work was released in 1201. But, it deeply looks that the book was written by other follower. Chu Cheng was a doctor excellent in the inspection and pulse method and his medical ideas prioritized Huo(火) in Mingmen(命門) and Spleen(脾). He expressed his opinions on the four phases of life, sexes and birth defects through Yangjing(陽精) and Yinxue(陰血). In addition, he explained the human pathology through Qixue(氣血). Unsmooth flow of Qi causes diseases by congestion. The entity circulating Yinxue is Yang and protested using urine to treat the hemoptysis(咳血) instead of medicine with cold features. It was frequently mentioned by his predecessors with the fact that Chu Cheng used different medications on housewives from widows and Buddhist nun monks. In addition, Chu Cheng proposed various opinions on cure, diagnosis, treatment, drug usage, pulse positions and hermaphrodites(半陰陽).

Objectives: Two historical evidence supported the concept of Gamrosu. The first one was Jeho-tang, a selected thirst quencher in Chosun Dynasty and the second one was Saeng-Maek-san, Dongeuibogam's recommendation as one of the qi-vigorating summer beverages. Gamrosu is a modified fasting therapy beverage which is manufactured from those two prescriptions and the carbohydrates (420.6 kcal/d). A retrospective observational study was conducted to evaluate the clinical outcomes. Methods: Thirty-three cases were reviewed at three local Korean Medical clinics that each site's participant has finished the modified fasting for 10 consecutive days. Clinical outcomes were reviewed at pre- and post-fasting sessions by retrieving the changes of body composition, blood pressure, blood chemistries & urine tests, and subjective symptoms & fatigue scores. Results: Demographics of the observed participants were 17 of male and 16 of female. Post-Gamrosu session, -6.89% of body weight, -8.97% of body fat mass were reduced with the nutrition indices being improved (P<0.001). -8.72% of systolic blood pressure, -39.86% of serum triglyceride, -6.75% of fast blood sugar and -8.12% of waist circumference were improved (P<0.05). The levels of high sensitivity C-reactive protein (-58.34%), CRP (-43.55%) and eosinophil (-21.30%) showed the significant diminished profiles (P<0.05). Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners. The fatigue scale scores indicated significant lower scores. Conclusions: Taken together, obesity-related clinical outcomes after a modified fasting therapy with Gamrosu were sufficiently feasible and the observed findings should be considered for further prospective clinical studies.

The effects of inorganic selenium (Se), selenate and selenite on Se balance levels in the different ruminal fluid fractions were studied using Japanese Corriedale wethers with an average body weight of 47 kg. A $3{\times}3$ Latin square design was used with three animal, three periods and three treatments. In each period, there was 7 d dietary adjustment followed by 5 d total collection of urine and feces. Ruminal fluid samples were obtained at 0, 1, 3, 5 and 7 h postprandially on the final day of the collection period. The three dietary treatments were: (1) without Se supplementation (control); (2) with Se supplement as sodium selenate; and (3) sodium selenite at a rate of 0.2 mg Se/kg dietary DM. The basal diet was timothy hay (Phleum pratense L.) fed 2% of body weight/d. Results indicated that Se balance were higher (p < 0.05) for those animals under supplementation than those animals under control. Overall data gathered showed a similar digestion balance of selenate and selenite in sheep. Inorganic Se, both selenate and selenite produced positive Se contents of the ruminal feed particles and protozoa. Bacterial Se increased (p < 0.05) on the first three hours post-prandially in Se supplemented diets. Gross ruminal fluid fraction, although there was improvement on their Se content under the supplemented diets, the changes were insignificant over the control. free inorganic Se and Se in soluble protein of the ruminal fluid were not significantly different for selenate and selenite. Most of the Se in the ruminal fluids of the animals under supplementation were insoluble, indicating the influence of rumen environments on Se bioavaliability.

Calcium (Ca) is an essential element to maintain body homeostasis. However, many factors disturb calcium absorption. Aspartic acid chelated calcium (AAC) was synthesized by new methods using calcium carbonate and aspartic acid. This study was carried out to investigate the bioavailability of AAC in Ca-deficient rats. The experimental groups were as follows: NC; normal diet control group, CD-C; untreated control group of Ca-deficient (CD) rats, CD-$CaCO_3$; $CaCO_3$ treated group of CD rats, CD-AAC; AAC treated group of CD rats, and CD-SWC; and seaweed-derived Ca treated group of CD rats. The Ca content of various types of Ca was held constant at 32 mg/day, and the four CD groups were fed for 7 days after randomized grouping. Ca content in serum, urine, and feces within feeding periods were analyzed to confirm Ca absorption. Serum Ca content was significantly higher in the CD-AAC (11.24 mg/dL) and CD-SWC (10.12 mg/dL) groups than that in the CD-C (8.6 mg/dL) group 2 hours following the first administration. The Ca content in feces was significantly lower in the CD-AAC (35.4 mg/3 days) and CD-SWC (71.1 mg/3 day) groups than that in the CD-$CaCO_3$ (98.7 mg/3 days) group (p > 0.05). AAC had a 2.3-fold higher absorption rate of Ca than that of SWC. No differences in fibula length were observed in the NC and CD groups. The fibula weights of the CD-AAC (0.33 g) and CD-SWC (0.33 g) groups increased compared to those in the CD-C (0.27 g) group; however, no significant difference was observed between the CD groups. We conclude that bioavailability of AAC is higher than that of seaweed-derived Ca or inorganic Ca. Thus, these findings suggest the AAC has potential as a functional food material related to Ca metabolism.

According to the World Health Organization (WHO), 1.37 million people died of lung cancer all around the world in 2008, occupying the first place in all cancer-related deaths. However, this number might be decreased if patients were detected earlier and treated appropriately. Unfortunately, traditional imaging techniques are not sufficiently satisfactory for early detection of lung cancer because of limitations. As one alternative, breath volatile organic compounds (VOCs) may reflect the biochemical status of the body and provide clues to some diseases including lung cancer at early stage. Early detection of lung cancer based on breath analysis is becoming more and more valued because it is non-invasive, sensitive, inexpensive and simple. In this review article, we analyze the limitations of traditional imaging techniques in the early detection of lung cancer, illustrate possible mechanisms of the production of VOCs in cancerous cells, present evidence that supports the detection of such disease using breath analysis, and summarize the advances in the study of E-noses based on gas sensitive sensors. In conclusion, the analysis of breath VOCs is a better choice for the early detection of lung cancer compared to imaging techniques. We recommend a more comprehensive technique that integrates the analysis of VOCs and non-VOCs in breath. In addition, VOCs in urine may also be a trend in research on the early detection of lung cancer.

The nutrient digestibility, nitrogen balance and in vivo metabolizable energy supply of Mucuna pruriens whole pods fed to growing Pelibuey lambs was investigated. Eight Pelibuey sheep housed in metabolic crates were fed increasing levels of Mucuna pruriens pods: 0 (control), 100 (Mucuna100), 200 (Mucuna200) and 300 (Mucuna300) g/kg dry matter. A quadratic (p<0.002) effect was observed for dry matter (DM), neutral detergent fibre (aNDF), nitrogen (N) and gross energy (GE) intakes with higher intakes in the Mucuna100 and Mucuna200 treatments. Increasing M. pruriens in the diets had no effect (p>0.05) on DM and GE apparent digestibility (p<0.05). A linear reduction in N digestibility and N retention was observed with increasing mucuna pod level. This effect was accompanied by a quadratic effect (p<0.05) on fecal-N and N-balance which were higher in the Mucuna100 and Mucuna200 treatments. Urine-N excretion, GE retention and dietary estimated nutrient supply (metabolizable protein and metabolizable energy) were not affected (p>0.05). DM, N and GE apparent digestibility coefficient of M. pruriens whole pods obtained through multiple regression equations were 0.692, 0.457, 0.654 respectively. In vivo DE and ME content of mucuna whole pod were estimated in 11.0 and 9.7 MJ/kg DM. It was concluded that whole pods from M. pruriens did not affect nutrient utilization when included in an mixed diet up to 200 g/kg DM. This is the first in vivo estimation of mucuna whole pod ME value for ruminants.

This study was performed to evaluate the effect of liver damage on toluene metabolism in rats pretreated with carbon tetachloride. Liver damage in rats was induced by administration of 0.1ml of carbon tetrachloride per 100g of body wight intraperitoneally every day for four weeks except the last day before sacrifice. One day before sacrifice, toluene was administered to the animals instead of carbon tetrachloride. Rats were sacrificed at the 1st, the 2nd, the 3rd and the 4th week after the first administration of carbon tetachloride. Based on the histopathological findings, liver weight and serum alanine aminotransferase, the $CCl_4$-preteated group was found to have gradual severe liver damage. Especially the degree of liver injury became increasingly severe throughout the whole course of the experiment. The contnts of hippuric acid in urine lower in the all groups pretreated with $CCl_4$than that of the control. The contents of hepatic cytochrome P450(CYP), benzylalcohol dehydrogenase and benzaldehyde dehydrogenase activities were decreased in $CCl_4$-pretreated rats than those of the control. The $CCl_4$treated animals showed the gradual decreased activities of these enzyme as injection times elapsed. Km values of the benzylalcohol dehydrogenase in pooled liver samples from $CCl_4$-pretreated or control groups were similar. On the other hand, Vmax values of the $CCl_4$-pretreated group was lower than of the control. Therefore, it can be concluded that reduction of the toluene metabolism in damaged rat liver induced with $CCl_4$was due to the inhibition of CYP content, bezylalcohol and benzaldehyde dehydrogenase activities which related with toluene metabolic enzyme system.

Urinary mutagenicity is widely recognized as a useful biomarker for the assessment of mutagen exposure level in human. In this study, we optimized the several parameters affecting the activity of Urinary mutagenicity using highly sensitive mutation test(microsuspension assay) instead of the conventional Ames test. First of all, we chose YG1024 as a highly sensitive strain from three str ains of Salmonella typhimurium(TA98, TA100, YG1024) using r epr esentative mutation substances, such as Benzo[a]pyrene, 2-Aminonaphthalene, 2-amino-3-methyl-9H-pyrido[2,3-b]indole($MeA{\alpha}C$) and cigarette total particulate matter(TPM). And we established the several kinds of test conditions such as number of bacter ia, concentr ation of metabolic activation system and incubation time for the most sensitive reaction. Also, we optimized efficient pre-treatment method using commercial C18 column. As a r esults, this method was shown a aver age of 94 % recovery value and 13 % relative standard deviation. When we compared the Urinary mutagenicity between several participants, we confirmed that compar ative measurements were possible for different levels of urine mutagenicity. In conclusion, the optimized highly sensitive mutation test to measure the Urinary mutagenicity may be useful in biological monitoring of mutagen exposure level.

The purpose of this study was to investigate sodium intake and protein metabolism for pregnant women in Korea. The relationship between salt consumption and hypertension, electrolyte changes in pregnancy, and the tendency of weight gain of pregnant women were also examined. The dietary survey and twelve or twenty-four hour's urine collection was performed in this study. The subjects were pregnant women who came to gynecology clinic for prenatal care from July to August in 1984. The results were as follows: 1) Intakes of calorie and iron of Korean pregnant women were 2,036 Kcal and 16mg per day per person. The calorie composition consists of 65% carbohydrate, 16% protein, and 19% lipids. The average level of all nutrients was about 87% of Korean Recommended Dietary Allowances. 2) The sodium intakes in pregnant women estimated by dietary survey was 318.6 mEq Na (7,966 mg Na), which is equivalent to 20.2 g NaCl. 3) Daily sodium excretion was 112.5 mEq per liter, that is equal to 147.4 mEq. Potassium excretion was 24.95 mEq per liter and creatinine excretion was 594.0 mg per day. 4) There were statistically significant correlations between sodium intake and the excretions of sodium, potassium and creatinine. The blood pressure was positively correlated with sodium intakes. As sodium and potassium ratio was increased, systolic blood pressure and diastolic blood pressure were also significantly increased 5) Urinary nitrogen and creatinine ratio known to be reliable index for nutritional status of protein was 5.5 : 1. These values were comparable to the values in American pregnant women. 6) The weight gain during the pregnancy was examined. There was little weight gain during the first trimester, because of nausea, vomit and decrease of appetite. The weight gain during the second trimester was 4.9Kg, and 11.1Kg for third trimester.

This study shows the result of the survey conducted for male adults who had to use wheelchairs. The objectives of this study are to develop and improve the clothes for the disabled people and to make those garments put into practice. For this purpose, the survey was conducted at first so as to understand the situation of the disabled peoples wearing clothes and the garment demands. This survey is to suggest the suited form of the pants they want. The result of the study is as follows. 1) The average age of the subjects was 38.4 years old. They have used wheelchairs for 12 years on the average. Most subjects two limbs were paralyzed because of the acquired spinal paralysis. 60 percent of them were wearing the urine bags all the time. The average size of the pants they purchased was 39 inches, which means that their waist and abdominal circumstance were very big. 2) Regarding the situation of wearing habits, although the subjects usually purchased ready-to-wear, most of them are very dissatisfied with them. Especially, they considered the size as their main dissatisfaction. The main concern for buying garments was how comfortable and mobile they are while wearing them. They also needed outdoor garments. Lastly, they looked forward to the shop specialized in the garments for disabled people. 3) The functional pants for adult men using wheelchairs had the same zipper as that of general pants. The waist belt was made of rubber to reduce the pressure on waist and to cover 2 inches (5 cm) of waist circumference. Also it should be made to secure each button within the belt in accordance with size. Finally, it was designed as formal wrinkled pants that had pockets within the reach of hands when the disabled used wheelchairs.
