  • Twenty male buffalo calves of 6-9 months of age (average body weight, 97 kg) were randomly allocated into two main groups of four (control) and sixteen (supplemented) calves. The supplemented group was further divided in to four equal sub-groups, with the two groups supplemented with a liquid preparation of urea-molasses, UML1, containing fish meal and UML2, containing formaldehyde treated deoiled mustard cake (FDMC) and the other two, with a semi-solid preparation, UMC1 with FDMC and deoiled rice bran (DORB) contributing similar level of CP as in UML2 and UMC2 with double the level of FDMC to that in UMC1. The control group was fed with DORB along with ad libitum wheat straw at 40:60 ratios. The rest of the groups were fed on the above diet supplemented with 500 g (as fed basis) of urea-molasses preparations. The experimental feeding was carried out for 24 weeks including a metabolism trial towards the end of experimental feeding. Daily feed intake and fortnightly change in live weight were also recorded during the study. Catalytic supplementation of 500 g urea-molasses induced 8-25% higher voluntary feed intake of wheat straw, resulting in 15-25% higher DM and OM intake. The digestibility of DM, OM, total carbohydrate, NDF, ADF, hemicellulose and cellulose in all the dietary groups were comparable. The CP digestibility of calves in supplemented groups were higher (p<0.05) than the control group. The balance of nutrients, viz. N, Ca and P, was also higher in the supplemented groups. Significantly higher intake of digestible CP coupled with other digestible nutrients attributed to higher TDN (1.67-1.78 vs. 1.37 kg) and ME (5.94-6.31 vs. 4.87 Mcal) intake in urea-molasses supplemented groups which resulted in higher live weight gain compared to that in control group (p<0.01). Between the supplements, UML2 and UMC2 faired non-significantly, indicating formalin treated mustard cake as a suitable replacement to fishmeal in the supplement. The overall ranking based on intake and digestibility of nutrients, live weight gain, economic evaluation and input-output relationship revealed that the rations with UML2 and UMC1 to be of greater value compared to other types. From the study it can be concluded that young ruminants can be reared successfully on a basal diet of deoiled rice bran and wheat straw supplemented with cheaper urea-molasses-mineral mix.

  • Nucleolin (C23) is an important anti-apoptotic protein that is ubiquitously expressed in exponentially growing eukaryotic cells. In order to understand the impact of C23 in radiation therapy, we attempted to investigate the relationship of C23 expression with the radiosensitivity of human non-small cell lung cancer (NSCLC) cells. We investigated the role of C23 in activating the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs), which is a critical protein for DNA double-strand breaks (DSBs) repair. As a result, we found that the expression of C23 was negatively correlated with the radiosensitivity of NSCLC cell lines. In vitro clonogenic survival assays revealed that C23 knockdown increased the radiosensitivity of a human lung adenocarcinoma cell line, potentially through the promotion of radiation-induced apoptosis and adjusting the cell cycle to a more radiosensitive stage. Immunofluorescence data revealed an increasing quantity of ${gamma}$-H2AX foci and decreasing radiation-induced DNA damage repair following knockdown of C23. To further clarify the mechanism of C23 in DNA DSBs repair, we detected the expression of DNA-PKcs and C23 proteins in NSCLC cell lines. C23 might participate in DNA DSBs repair for the reason that the expression of DNA-PKcs decreased at 30, 60, 120 and 360 minutes after irradiation in C23 knockdown cells. Especially, the activity of DNA-PKcs phosphorylation sites at the S2056 and T2609 was significantly suppressed. Therefore we concluded that C23 knockdown can inhibit DNA-PKcs phosphorylation activity at the S2056 and T2609 sites, thus reducing the radiation damage repair and increasing the radiosensitivity of NSCLC cells. Taken together, the inhibition of C23 expression was shown to increase the radiosensitivity of NSCLC cells, as implied by the relevance to the notably decreased DNA-PKcs phosphorylation activity at the S2056 and T2609 clusters. Further research on targeted C23 treatment may promote effectiveness of radiotherapy and provide new targets for NSCLC patients.

  • Lipid-lowering effects of the inulin have been demonstrated in animal, yet attempts to reproduce similar effects in humans have generated conflicting results. In this study, the lipid-lowering potential of inulin and especially its effect on bile acid and neutral sterol excretion were investigated in Korean postmenopausal women. Nineteen postmenopausal women were randomly divided into two groups in a double-blind parallel design and consumed one of two supplements for 12 weeks; placebo of 8g maltodextrins/sucrose mixture (placebo group) or 8g inulin (inulin group). There were no significant changes in body weight during the supplementation period in either inulin or placebo group. Dietary consumption of animal fat in both group tended to decrease after 12 weeks of experiment. Intake of cholesterol was lower in placebo group, whereas the decrease of cholesterol intake in inulin group did not reach statistical significance after 12 weeks. The levels of serum total cholesterol (TC) and LDL-cholesterol (LDL-C) were significantly decreased in both placebo (p<0.05) and inulin group (p<0.01) after supplementation for 12 weeks compared with the baseline. The levels of serum triglyceride (TG) and HDL-cholesterol (HDL-C) were not significantly affected by inulin supplements, but atherogenic index (AI) and LDL-C/HDL-C ratio (LHR) as a predictor for coronary heart disease were improved (p<0.01) significantly after inulin supplementation. Therefore, inulin supplement may decrease the risk of cardiovascular disease via improving blood cholesterol level. Fecal weight and pH were not changed after 12 weeks of supplementation. There were no statistically significant changes for the fecal short-chain fatty acids (SCFAs). In inulin group, fecal deoxycholic acid (DCA) was significantly lowered compared with the baseline (p<0.05) whereas other bile acids were not changed. During the 12 weeks of intervention, no differences were found in fecal excretion of neutral sterol in the two groups. In summary, dietary inulin decreases serum TC, LDL-C, AI, LHR and lowers excretion of fecal DCA in the Korean postmenopausal women. These results support the use of inulin for reducing risk factors for hyperlipidemic postmenopausal women. However, the exact mechanism (s) responsible for the blood lipid lowering action of inulin including altered fecal bile acid remain to be elucidated.

  • Although research efforts for brain waves have prospered in medicine and engineering, acupuncture still has a long way to go regarding researches on brain waves analysis. Thus this study set out to analyze brain waves stimulated by indirect mugwort moxibustion, which was part of acupuncture techniques, and to investigate their correlations with the automatic nervous system. For the experiments, stimulation was given to Jungwan, Shingwol and Gwanwon, which were some of the spots on the body suitable for acupuncture, through indirect mugwort moxibustion. The subjects' brain waves were measured before the stimulation, during the stimulation, and one hour and two hours after the stimulation. The measurements were analyzed with Matlab 7.0 for FFT and frequency power spectrum. Then the ${\alpha}$, ${\beta}$, ${\delta}$, and ${\theta}$ waves were analyzed and examined for changes to the percentage of each frequency and to the amplitude of vibration according to the stages of stimulation. The EEG data of the entire brain were translated into FFT to analyze the percentage of the ${\alpha}$, ${\beta}$, ${\delta}$, and ${\theta}$ waves. As a result, the ${\alpha}$ waves recorded a double increase after the stimulation. The power spectrum analysis results of the entire brain decreased the ${\alpha}$ and ${\beta}$ waves dropping in the energy level, which suggested that the parasympathetic nerves were activated. When the results of the study were compared with those of the previous study, it's confirmed that indirect moxibustion stimulation could cause changes to the automatic nervous system and bring stability to those who were nervous or under stress due to the proportionate increase of the ${\alpha}$ waves.

  • The ship sailing among waves are suffered the various wave loads that comes from its motion throughout its life. Because there are dynamic, the analysis of ship structure must be considered as the dynamic problem precisely. In the rationally-based design, the dynamic structural analysis is carried out using dynamic wave loads provided from the results of the ship mouton calculation as the rigid body. This method is based on the linear theory assumed low wave height and small amplitude of motion. But at the rough sea condition, high wave height, relatively ship's depth, is induced the large ship motion, so the ship section configulation below water line is rapidly changed at each time. This results in non-linear problem. Considering above situation in this paper, the strength analysis method is introduced for the hull glider among waves considering non-linear hydrodynamic forces. This paper considers that the overall or primary level of the ship structural dynamic loading and dynamic response provided from the non-linear wave forces, and bottom and bow flare impact forces estimated by momentum slamming theory, in which the ship is idealized as a hollow thin-walled box beam using thin-walled beam theory and the finite element method. This method is applied to 40,000 Ton Double-Skin Tanker and attention is paid to the influence of the response of ship speed, wave length and wave height compared with linear strip theory.

  • The surgical treatment of tetralogy of Fallot [TOF] was initiated by Blalock and Taussig in 1945 with the establishment of the subclavian artery to pulmonary artery anastomosis. In an imaginative and daring effort, in 1954, Lillehei and collaborators [1955] using controlled cross-circulation, carried out the first intracardiac repair of TOF by closing the ventricular septal defect [VSD] and relieving the pulmonary stenosis under direct vision. Nowadays, total correction is the ideal operation for treatment of TOF and is accomplished with extracorporeal circulation. And the results of surgery for TOF have steadily improved over the years, thanks to important contributions of many surgeons. Nevertheless because of its protean physiologic and anatomic presentation, TOF continues to offer challenges to cardiologist and cardiac surgeons. Thirty two cases of TOF have undergone total corrective surgery using extracorporeal circulation in the Department of Thoracic & Cardiovascular Surgery, Pusan Paik Hospital, Inje University, from Oct. 1985 to Feb. 1990. Clinical considerations were applied to these cases and the results were obtained as follows. 1. The heart lung machine used for extracorporeal circulation was SarnsO 7000, 5-head roller pump, and the number and type of oxygenators were 10 of bubble type and 22 of membrane type. The mean bypass time was 148.9 minutes and the mean aortic cross clamp time was 123.8 minutes. The GIK [glucose-insulin-potassium] solution was used as cardioplegic solution for myocardial protection during operation. 2. 20 cases were male and 12 were female, the mean age was 8 years old and the mean body weight was 25Kg. 3. The preoperative symptoms were cyanosis [29 cases], squatting [27 cases] and etc. The mean values of preoperative Hb., Hct., and SaO2 were 16.5 gm /dl, 50.3%, and 78.5%. 4. Combined anomalies were noticed in 16 cases [50%]. Among them 10 cases were PFO and 6 cases were ASD. 5. The degree of aorta overriding were 25% in 5 cases, 25 ~ 50% in 22 cases and above 50% in 5 cases. The dPA/Ao [ratio of diameter of pulmonary artery trunk to ascending aorta] were below 25% in 5 cases, 25 ~ 50% in 10 cases, 50 ~ 70% in 6 cases and above 75% in 11 cases. 6. The types of RVOT [right ventricular outflow tract] stenosis were valvular and infundibular in 14 cases [43.6%], diffuse hypoplastic type in 12 cases [37.5%], infundibular in 5 cases, and valvular and supravalvular in 1 case. 7. One stage radical corrective surgery was applied to the all cases. In widening of the RVOT, 3 types of patches were used: MVOP [monocusp ventricular outflow patch, Polystan BioprosthesesO] in 3 cases, knitted Dacron vessel patches in 2 cases, and double layer with bovine pericardium and woven Dacron prosthesis in 26 cases. 8. Postoperative complications were occurred in 15 cases. Among them, low output syndrome were occurred in 10 cases [31.3%] and 2 of them were expired postoperatively.

  • Objectives: This research was aimed 1) to find out various subjective symptoms cancer patients had, 2) to find out the quantitative difference of symptoms occurring according to the area of cancer, current treatment methods, and relapse of the cancer and 3) to analyze the relationship between the occurrence of symptoms. Methods: This study was a survey about the various subjective symptoms cancer patients had. The subjects were 48 cancer patients in a double-blinded randomized controlled trial about the effectiveness of Korean Red Ginseng (KRG) treatments. Surveys were examined before Korean Red Ginseng (KRG) treatments. The questionnaire consisted of demographic research, patient history and accompanying symptoms. The symptoms part consisted of 4 questions on general symptoms (vertigo, hot flush, rash, insomnia), 2 questions on digestion symptoms (anorexia, dyspepsia), 2 questions on excretions (diarrhea, constipation), and 5 questions on symptoms in different body parts (headache, dryness of lips, chest pain, aphthous ulcer, nose bleeding). The questionnaire was used to research presence of symptoms and relationships between the occurrence of symptoms. Results: A total of 48 patients took part in this survey. Dizziness was the most frequent subjective symptom patients had (64.58%), followed by dry mouth (43.75%), headache (43.75%), insomnia (41.67%), anorexia (37.5%) and chest discomfort (37.5%). The presence of these subjective symptoms was partially related to the patient's history details - type of cancer, method of cancer treatment (chemotherapy, radiotherapy), termination of treatment, presence of pain, fatigue and recurrence, etc. Factor analysis was conducted to analyze the relationship between the occurrence of symptoms. It suggested 5 factors as a result, but there was a limitation that only a low level of correlation was shown among them. Conclusions: We were able to analyze the occurrences and the relationships among them for accompanying subjective symptoms in cancer patients. However the results of the study are limited in that only 48 patients participated. The symptoms in cancer patients showed a tendency for clustering, occurring simultaneously or continuously rather than occurring alone. The study of these symptom clusters is worth further study, for it is similar to the Symptom Differentiation System in Traditional Korean Medicine. For effective approach to the treatment of cancer in Traditional Korean Medicine, further research on the Korean traditional view of cancer patients should be done based on this research, regarding various symptoms and those relationships on a larger scale.

  • For stimulating the in vivo secretion of IGF-1 (insulin-like growth factor-1) which is well known to promote the various physiological actions in human body, the natural herbal extract, YGF251 (young growth factor 251), was developed and evaluated for its effect as IGF-1 secretagogue in this study. The clinical study was peformed as double blind test, and 31 adult female and male volunteers between the age of 40 and 70 were investigated for their changes of concentration of IGF-1 , insulin level, weight, blood pressure, and liver and kidney functions. As the result of paired sample test on the change of the concentration of IGF-1, in YGF251 treated group, it was 245.6 ng/mL before dosing. The concentration of IGF-1 was increased to 269.3 ng/mL after a month and to 275.6 ng/mL after two months, and both were statistically significant (p〈0.05). While in control group, the concentration of IGF-1 was 280.0 ng/mL before dosing, but decreased to 239.2 ng/mL after a month and to 230.2 ng/mL after two months, and both were also statistically significant (p〈0.05). In YGF251 treated group, the concentration of insulin in blood increased about 2 times after a month dosing as an average level, but in control group, it showed a decrease of 36% compared with before dosing. And there were little changes regarding to the measured weight and blood pressure. Various measured data in order to observe the alteration in liver and kidney functions by the administration of YGF251 showed a little change within measuring error range.

  • Vest is a general term for a sleeveless upper garment and it derives from a kolobus of a sleeveless tunic style that was started to be worn as a substitution of a chiton by the peasantry in Greek period. The kolobus started to be called a colobium or a tunica from Roman period and the former was named for a vest style tunica which was worn by the people of the lower classes in early Roman period. Similarly, a German colobium of North Europe which was worn during the same period was the same kind of clothe as the Roman colobium. The colobium came to be worn over a dalmatica as an outer garment by early Christians when it was the Middle Ages, who succeeded the tradition of colobium as they went through ancient Rome, Creek and Byzantine days. North Germans also succeeded the colobium tradition of ancient Germans as it was and so continued to wear it in tight style. The simple vest style of colobium was getting vanished from the mid of the Middle Agnes and a new style of vest named jupon was started to be worn by soldiers. The jupon was to protect soldiers' bodies from either were cold weather or enemies wearing under armors as it was made with double cotton pad by quilt. From 14th century, the jupon began to be worn by not only soldiers but also the humble of lower classes. All the jupon which were made in quilting and padding of that time began to be named a pourpoint by the humble. When Renaissance in 16th century came, the pourpoint began to be developed to an exaggerating body-line style. The neckline of pourpoint was getting highly influenced by Spain and a peacecod-belly of it emphasized the exaggerated masculine beauty of Renaissance by padding in round. The sleeves were puffed out and the whole purpoint was made to expose an inner chemise by slashing vertically or obliquely. But in 17th century, the pourpoint has been changed into more simple style without padding, puffing out and slashing influenced by the citizens' clothes of Netherlands. The pourpoint came to be more comfortable bulky style with short sleeves or sleeveless and straight side lines. The pourpoint in mid 17th century turned to be a bolero jacket style by gradually being tightened. It had been then changed into a vest style with sleeves and worn under an overcoat with the name of vest in the end of 17th century. The early vest was 2∼3 inches les in length than the overcoat and had long sleeves and many ornamental buttons on front. It was also made as a home wear to be worn it alone at home. In 18th century, the length of the vest became shorter compared with that of 17th century and the most important decorative item in clothes. It again came to have complete sleeveless vest style and had very short length reaching waist in the end of 18th century. When it was in 19th century, the vest had developed into more various style and colors and style had been applied to be worn by individuals with their tastes. Around the end of 19th century, the increasing tendency to be casual by industrialization influenced on clothes in all aspects of life and so the male vest has been gradually changed into more casual style. Nowadays, it has been developing into various uses in modern male clothes to show their characters.

  • Electron microscopic studies on the ultrastructure of the mouse oocyte were made to investigate the inhibition of germinal vesicle breakdown by dibutyryl cAMP. The nuclear membrane of the dibutyryl cAMP-treated oocyte is characterized by a decreased degree of folding, maintains the normal double membrane structure, and shows an increased occurrence of the nuclear pore. It is suggested that these may be related to the suppression of the maturation of oocytes at the germinal vesicle. Mitochondria in the control cell were shown to be spread evenly throughout the cytoplasm and structurally underdeveloped or transitionary having little cristae development. On the contrary, mitochondria in the treated oocyte were found to be localized mainly around the nucleus and to show a greater extent of cristae development. The oocyte treated with dibutyryl cAMP appears to have fewer and structurally simpler lysosomes as compared to the control. The Golgi complex in the control oocyte exhibits the typical granular and lamellar structure, whereas that in the treated cell is poorly developed. Many multivesicular bodies, tonofilaments, and free ribosomes were observed in the control as well as in treated cells. The microvilli become structurally irregular, and a development of the perivitelline space is apparent in the treated oocyte. It is concluded that there is no basic difference in the ultrastructure between the oocytes treated with dibutyryl cAMP for 24 hours in the medium and those collected directly from the follicle. However, the finding that dibutyryl cAMP induces a development of more pores along the nuclear membrane strongly suggests the possibility that this compound inhibits the maturation of oocytes by influencing the permeability of the nuclear membrane.
