  • Two completely randomized block design experiments were conducted to evaluate the effect of gamma irradiation processing of canola meal on performance parameters of broiler chicks (Ross 308) and protein quality of canola meal. Protein efficiency ratio (PER) and net protein ratio (NPR) were measured as indices of canola meal protein quality. Samples of canola meal were tested for nutritional value after being irradiated at dose levels 10, 20 and 30 kGy. Glucosinolate content was reduced 40, 70 and 89 percent at irradiation dose levels of 10, 20 and 30 kGy respectively (p<0.01). Percent of erucic acid in total fatty acid content increased 44, 58 and 48% as a function of radiation dose (p<0.01). Dose levels did not affect feed conversion ratio (FCR) and body weight gain of chicks (p>0.05). Liver weight was decreased by irradiation dose (p<0.05). The same trend was observed for kidney weights, but this trend was not significant (p>0.05). Gamma irradiation processing of canola meal had no significant effect on $T_3$ level in blood of chickens that consumed canola meal, but $T_4$ level of chicken blood at the 30 kGy dose decreased significantly (p<0.05). PER and NPR were not affected by radiation dose level (p>0.05). Gamma irradiation seems to be a good procedure to improve the nutritional quality of canola meal.

  • Erythropoietin (EPO), a glycoprotein hormone produced from primarily cells of the peritubular capillary endothelium of the kidney, is responsible for the regulation of red blood cell production. We have been investigating the roles of glycosylation site added in the biosynthesis and function of recombinant protein. We constructed three EPO mutants ($\Delta$69, $\Delta$105 and $\Delta$69,105), containing an additional oligosaccharide chains. EPOWT and EPO$\Delta$69 were effectively expressed in transient and stably transfected CHO-K1 cell lines. But, it wasn't detected any protein in the culture medium of EPO$\Delta$105 and EPO$\Delta$69,105 mutants. The growth and differentiation of EPO-dependent human leukemic cell line (F36E) were used to measure the cytokine dependency and in vitro bioactivity of rec-hEPO. MTT assay values were increased by survival of F36E cells at 24h. To analysis biological activity in vivo, two groups of ICR-mice (7 weeks old) were injected subcutaneously with 10 IU per mice of rec-hEPO molecules on days 0 and 2. Red blood cell and hematocrit values were measured on 6 days after the first injection. The hematocrit values were remarkably increased in all treatment groups. The pharmacokinetic analysis was also affected in the mice injected with rec-hEPO molecules 2.5 IU by tail intravenous. Protein samples were detected by Western blotting. An EPO$\Delta$69 protein migrated as a broad band with an average apparent molecular and detected slightly high band. Enzymatic N-deglycosylation resulted in narrow band and was the same molecular size. The biological activity of EPO$\Delta$69 was enhanced to compare with wt-hEPO. The half-life was longer than wt-hEPO. The results suggest that hyperglycosyalted recombinant human erythropoietin (EPO$\Delta$69) may have important biological and therapeutic good points.

  • Objectives : The transition of the 29 diagrams of Heart originated from MingTangZangFuTu will be used to understand the shape of heart and the changes of people's understanding of heart. Methods : The 29 diagrams of Heart originated from MingTangZangFuTu are divided according to their shape elements (Heart itself, internal curvatures, structures above heart, wuzangxi, and excursus). Then its transitions are analyzed, and each shape element is compared to modern anatomy and its textual basis is searched. Results : The lengthy cylinderical organ situated above the heart is composed of upper part consisting with joints and the lower part void of joints. The upper part is Pyewan (such as the lungs) and fall into trachea. The lower part is Xinxi or Feixi which are either relative vein (or aorta) or left bronchus that passes behind the heart. This depiction of the structures around the heart can be considered to have composed by actual observance of a physical heart, a method that is similar to anatomy. However, the shape of the heart itself is described as a lotus flower that has not been bloomed, a depiction which finds its origin from Zhongguangbuzhu huangdineijing suwen (762). The three short curvatures inside the heart is described as Pericardium, influenced by Shisijingfahui (1341) in its depiction, or as sammo, influenced by Nanjing. Structures that are connected directly from the heart to spleen, kidney, and uterus are not found in modern anatomy. The saying in Excursus "All cords of five internal organs belong to heart" is based on Huatuoxuanmenneizhaotu, and this is changed to the saying cords of four internal organs belong to heart in Leijingtuyi for the first time. Conclusions : The authors of medical scriptures at the time did not have a method of direct observance when they were copying heart diagrams. Therefore, they made changes to the source material's diagram and excursus while being influenced by Nanjing, Huatuoxuanmenneizhaotu, and Shisijingfahui. Then the doctors' understandings with regards to the shape and function of heart were reflected during that process.

  • Studies were carried out to explore the influence of dietary protein level on bone metabolism in uninephrectomized rat (experimental renal failure model) when dietary Ca and P contents were equal. Male rats were uninephrectomized or sham operated and fed 8%, 15% and 40% casein diets for 24 weeks. Ca and P contents of the all diet were 0.4% and 0.6% respectively. The results are summarized as follows. We did not found any significant difference in PTH and Ca level of the serum, Ca intake and Ca excretion among the experimental groups. There was significant positive correlation between the PTH and phosphate level. There was significant inverse correlation between serum Ca and creatinine level. The effect of the dietary protein level and renal mass loss on density and Ca contents of the bone were small and different according to the kinds of the bone. Low protein diet was associated with a significant enhancement of scapular density. Femur and vertebra density, however, were not influenced by dietary protein level and uninephrectomy. Light microscopic examination showed several calcified foci in the kidney in all experimental groups. Low protein diets have been used for a long time in the conservative management of chronic renal failure as they have a beneficial effect in preventing the appearance of symptoms. This study elucidated that part of beneficial effects of the low protein diet related to the suppression of the hyperphosphatemia. And these results, even though uninephrectomized rats fed high protein diet, the secondary hyperparathyroidism is supressed by the regulation of the P level. Therefore this study emphasized the need to pay more attention to the regulation of dietary P level as well as dietary protein content in chronic renal failure.

  • To study the effect of dietary docosahexaenoic acid (DHA) enrichment on the expression of hepatic genes in pigs, weaned, crossbred pigs (30 d old) were fed diets supplemented with either 2% tallow or DHA oil for 18 d. Hepatic mRNA was extracted. Suppression subtractive hybridization was used to explore the hepatic genes that were specifically regulated by dietary DHA enrichment. After subtraction, we observed 288 cDNA fragments differentially expressed in livers from pigs fed either 2% DHA oil or 2% tallow for 18 d. After differential screening, 7 genes were found to be differentially expressed. Serum amyloid A protein 2 (SAA2) was further investigated because of its role in lipid metabolism. Northern analysis indicated that hepatic SAA2 was upregulated by dietary DHA enrichment (p<0.05). In a second experiment, feeding 10% DHA oil for 2d significantly increased the expression of SAA2 (compared to the 10% tallow group; p<0.05). The porcine SAA2 full length cDNA sequence was cloned and the sequence was compared to the human and mouse sequences. The homology of the SAA2 amino acid sequence between pig and human was 73% and between pig and mouse was 62%. There was a considerable difference in SAA2 sequences among these species. Of particular note was a deletion of 8 amino acids, in the pig compared to the human. This fragment is a specific characteristic for the SAA subtype that involved in acute inflammation reaction. Similar to human and mouse, porcine SAA2 was highly expressed in the liver of pigs. It was not detectable in the skeletal muscle, heart muscle, spleen, kidney, lung, and adipose tissue. These data suggest that SAA2 may be involved in mediation of the function of dietary DHA in the liver of the pig, however, the mechanism is not yet clear.

  • Zn is an essential nutrient that is required in humans and animals for many physiological functions, including immune and antioxidant function, growth, and reproduction. The present study evaluated whether Zn deficiency would negatively affect bone-related enzyme, ALP, and other bone-related minerals (Ca, P and Mg) in rats. Thirty Sprague Dawley rats were assigned to one of the three different Zn dietary groups, such as Zn adequate (ZA, 35 mg/kg), pair fed (PF, 35 mg/kg), Zn deficient (ZD, 1 mg/kg) diet, and fed for 10 weeks. Food intake and body weight were measured daily and weekly, respectively. ALP was measured by spectrophotometry and mineral contents were measured by inductively coupled plasma-mass, spectrophotometer (ICP-MS). Zn deficient rats showed decreased food intake and body weight compared with Zn adequate rats (p<0.05). Zn deficiency reduced ALP activity in blood (RBC, plasma) and the tissues (liver, kidney and small intestine) (p<0.05). Also, Zn deficiency reduced mineral concentrations in rat tissues (Ca for muscle and liver, and Mg for muscle and liver) (p<0.05). The study results imply the requirement of proper Zn nurture for maintaining bone growth and formation.

  • Background/Aims: Dong-Moo Lee Jae-Ma(1837-1900) confirmed the sasangchaejil theory based on the sasang-medicine. This theory has been the main-stem of oriental medicine during 100 years in Korea. But rarely anyone has tried to prove this theory systemicaly. So we have a trial to clarify any relationship between the sasangchaejil and the laboratory and clinical results of mass screening tests. Methods: We evaluated the laboratory values of 280 people who had taken many clinical and laboratory tests. The laboratory examinations were complete blood count, liver and kidney function test, ultrasonogram of the abdomen and breasts, gastrofiberscope, many tumor markers body mass index, blood pressure, glucose, and electrocardiogram, etc. Results: 1) Among the 280 subjects, 187/66.8% were sowumin, 58/20.7% were taewumin and 35/12.5% were soyangin. 2) Those who reacted positive to HBsAb were 22 subjects(62.8%) in soyangin, 57.2% in sowumin and 55.1% in raewumin. But there were no significant correlations. 3) 45 subjects(72.4%) in taewumin had obesity, fatty liver and hyperlipidemia.(P<0.05) 4) 20.6% in taewumin had abnormal LFT suggesting hepatic disease. It was statistically sigificant.(P<0.05) 5) An anemic state was present in women of soyangin and sowumin mostly. Since an iron deficiency anemia is common in women, there were no significant corelations among sasangchaejil. Also urinary tract infectons were common in women. 6) 6 subjects in taewumin(10.3%) had cardiac problems, while only one case(2.8%) occured in soyangin and 7 cases(3.7%) in sowumin. Taewumin was significantly high.(P<0.05) 7) In the case of gastric disease, there was no distinguishable difference among sasangchaejil.(taewumin 37.9%, soyangin 31.4% and sowumin 35.2% rrespectively) 8) There was no significant difference beteen subjects with different blood types using sasangchaejil. Conclusions: There were some significant relationship between sasangchaejil and diseases prevalent to them by the theory of sasang-medicine. But Lee didn't considered the differences of gender, the change of body status according to the development of culture, and circumstances of their lives. Also he didn't consider the existence of infectious agents. Now more systemic study with larger populations are requied.

  • This study was investigate the influences of wild haw (Crataegus pinnatifida $B_{UNGE}$) on lowering blood urea nitrogen (BUN) and creatinine concentrations in dyslipidemic rats. Four groups of rats were fed different diets for 5 weeks: basal diet (BD group), nondyslipidemic diet+feral haw extract (NDF group), dyslipidemic diet (DLD group), dyslipidemic diet+feral haw extract (DFH group). BUN, creatinine and uric acid concentrations were significantly higher in the DLD group than in the BD group. However, DFH group significantly lowered BUN, creatinine and uric acid concentrations compared to the DLD group. Amylase activity was significantly lower in the DLD group than in the BD group, while DFH group significantly higher compared to the DLD group. Lipase activity was also also significantly lower in the DLD group than the other group. Accordingly, these results suggest that haw extract could be effective for improving kidney function in dyslipidemic rats.

  • A 65-year-old woman was admitted due to poor oral intake and a dry cough over the previous 3 months. The physical examination was remarkable for bibasilar crackles, and plain chest radiography showed reticulation in both lower lung fields. A pulmonary function test demonstrated a restrictive pattern with a reduced diffusing capacity of the lung for carbon monoxide. High resolution computed tomography showed reticulation and honey-combing in both peripheral lung zones, which was consistent with usual interstitial pneumonia pattern. Her skin showed livedo reticularis. The erythrocyte sedimentation rate and C-reactive protein level were elevated, and hematuria was noted on urinary analysis. A serologic test for auto-antibodies showed seropositivity for Myeloperoxidase-Anti-neutrophil cytoplasmic antibody (MPO-ANCA). A kidney biopsy was performed and showed focal segmental glomerulosclerosis. She was diagnosed as having pulmonary fibrosis with microscopic polyangiitis (MPA) and treated with high dose steroids. Here we report a case of pulmonary fibrosis coexistent with microscopic polyangiitis.

  • Yukmijihwang-tang(YM) is a noted herbal prescription in Chinese and Korean traditional medicines, and it has been known to reinforce the vital essence and has been widely used for a variety of disease such as stroke, osteoporosis, anti-tumor, and hypothyrodism. Regarding its traditional use, YM has been known to reinforce the Yin (vital essence) of liver and kidney. Also it has been known to reinforce nutrition and biological function in brain. Recently, studies suggested that YM increase antioxidant activities and exert the protective effect against oxidant-induced liver cell injury. We investigated the high-throughput gene expression analysis on the Yukmijihwang-tang administrated in SD rats. Microarray data were validated on a limited number of genes by semiquantitative RT-PCR and Western blot analyses. The recent availability of microarrays provides an attractive strategy for elaborating an unbiased molecular profile of large number of genes in drug discovery This experimental approach offers the potential to identify molecules or cellular pathways not previously associated with herbal medicine. Total RNA from normal control brain and Yukmijihwang-tang administrated brain were hybridized to microarrays containing 10,000 rat genes. The 52 genes were found to be up-regulated(twice or more) excluding EST gene. The nine genes were found to be down-regulated(twice or more) excluding EST gene. Gene array technology was used to identify for the first time many genes expression pathway analysis that arecell cycle pathway, apoptosis pathway, electron transport chain pathway, cytoplasmic ribosomal protein pathway, fatty acid degradation pathway, and TGF-beta signaling pathway. These differentially expressed genes pathway analysis have not previously been iavestigated in the context of herbal medicine efficacy and represent novel factors for further study of the mechanism of herbal medicine efficacy.
