Purpose : We studied the usefulness of transcutaneous bilirubinometers in follow-up of bilirubin levels during phototherapy in neonatal jaundice patients. Methods : Transcutaneous bilirubin (TcB) was measured twice per day on 90 neonatal jaundice patients without risk factors of jaundice by transcutaneous bilirubinometer JM-103(Minolta/Hill-Rom Air-shields, Japan). TcB was measured simultaneously on the patched-forehead (TcB-PF), patchedchest(TcB-PC), unpatched-forehead (TcB-UF) and unpatched-chest (TcB-UC) of infants with neonatal jaundice. Plasma bilirubin (PB) was measured by American Optical bilirubinometer (American Optical Co, Buffalo, USA) within 30 minutes after transcutaneous bilirubinometer measurement. Each TcB was compared with PB. Results : In the study group, the mean gestational age was $38.6{\pm}1.3wk$, the mean birthweight was $3,207.0{\pm}472.1g$, the mean age at start of phototherapy was $4.9{\pm}0.9days$ and the mean duration of phototherapy was $1.3{\pm}0.6days$. The correlation between TcB and PB level was observed. The correlation between TcB of the patched part (TcB-PF, TcB-PC) and PB was more significant than that of the unpatched part (TcB-UF, TcB-UC) and PB. The most significant correlation was between PB and TcB-PC. Conclusion : TcB was useful in the follow-up of jaundice during phototherapy as well the screening of jaundice in neonatal jaundice patients. TcB of patched-chest area was the most reliable site in transcutaneous bilirubinometer examination in neonatal jaundice patients.

Purpose: The purpose of the study is to investigate the relationship between total serum bilirubin(TSB) and transcutaneous bilirubinometry(TcB) in neonates with jaundice. Method: TcB from various sites(forehead, sternum, abdomen, buttock, hand, dorsalis-pedia) was measured using a JM-102 in a total of 102 neonate, 42 female and 60 male, with the mean 37.5 gestational week and the mean 2,903 gram of birth weight, as well as TSB from capillary punctures. Result: The mean bilirubin was 11.73 in serum, 20.55 on the forehead, 17.23 on the sternum, 16.19 on the abdomen, 18.22 on the buttock, 15.83 on the hand and 15.49 on the dorsalis-pedia. The relationship between TSB and TcBs were formulated by simple regression with 0.406 < r < 0.668(p < .000). A higher relationship was revealed between TSB and TCB at the forehead in infants of full-term, ABO incompatibility, and Hb greater than 16 mg/dl(r =0.725, 0.790, and 0.717, retrospectively). Phototherapy altered the measurement of TcB per site. Conclusion: TcB on the forehead is a reliable, noninvasive and convenient measurement of TSB in normal infants(Institutions need to establish quantitative equations representing the specific relationship between TSB and TCB according to the hemodynamic problems of infants such as ABO incompatibility, or low Hb).

The purpose of this study was to determine whether vitamin {TEX}$B_{6}${/TEX} deficiency and age affect the blood cho-lesterol profile in exercising rats. Fifty four rats were fed either a viramin {TEX}$B_{6}${/TEX} deficient dief(-{TEX}$B_{6}${/TEX}) of a control diet(+{TEX}$B_{6}${/TEX}) for 6 weeks, then subdivided into 3 groups:non-exercise group(NE), exercise and sacrifice group(ES), exercise and recuperation group(ER). ES group was exercised in treadmill({TEX}$10^{o}${/TEX}, 0.5~0.8km/h) for 2 hours and sacrifice. ER group was recuperated three days with respective diet after exercise. At week 3 and 6, and level of plasma total cholesterol(TC), high density lipoprotein cholesterol(HDL_C) and low density lipoprotein cholesterol(LDL_C) were compared. In NE group, there was no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats. The plasma levels of TC and LDL_C of 6 weeks were higher than those of 3 weeks and on difference in HDL_V between 3 weeks rats and 6 weeks rats. In ES group, there was also no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats and there was no difference in TC, LDL-cholesterol between 3 weeks rats and 6 weeks rats. The level of HDL_C pf 6 weeks was lower than that of 3 weeks rats. In ER group, there was no difference in the levels of TC and LDL_C not only between +{TEX}$B_{6}${/TEX} rats and-{TEX}$B_{6}${/TEX} rats but also between 3 weeks rats and 6 weeks rats. The level of HDL_C was lower in -{TEX}$B_{6}${/TEX} rats than in +{TEX}$B_{6}${/TEX} rats and higher in 6 weeks rats than in 3 weeks rats. These results suggest that vitamin {TEX}$B_{6}${/TEX} deficiency may affect the HDL_C during exercise and after recuperation. The desirable effect of exercise on plasma Cholesterol profile is strengthened in adult age than young age.

The purpose of this study was to determine whether vitamin B6(B6) deficiency affects fuel utilization and blood cholesterol profile with exercise-training. Twenty-four rats were fed a B6 deficient(-B6) diet or a control (+B6) diet for 5 weeks and either exercised(EX) or nonexercised (NE). EX rats were exercised on treadmill(10$^{\circ}$, 0.5-0.8km/h) for 20 minutes everyday. Glucose(GLU), glycogen (GLY), protein(PRO), trglyceride(TG), free fatty acid(FFA), total cholesterl(TC), HDL-cholesterol(HDL-C) and LDL-choleterol(LDL-C) were compared in plasma(P), liver(L) and skeletal muscle(M) of rats. There was a vitamin effect on the level of P-GLU, P-TG, M-TG, L-GLY, L-PRO and an exercise effect on the level of P-PRO, P-FFA, M-PRO, L-GLY, L-TG, P-TC, P-HDL-C, P-LDL-C. Compared to +B6 rats were lower and there were no differences in P-GLU, P-FFA, P-TG. M-GLY, L-TG, P-TC and P-HDL-C. In EX group, the level of P-TG was higher and M-PRO was lower in -B6 rats. There were no differences in M-GLY, L-TG, P-TC and P-HDL-C. These results suggest that a lowered intake of vitamin B6 may impair the adaptation of animals to fuel metabolism related to a decrease of fatty acid oxidation and attenuates the exercise-traning effect on blood lipid profile.

Intravascular large B-cell lymphoma (IVLBCL) is a subtype of diffuse large cell lymphoma, characterized by proliferation of lymphoid cells in the intravascular space of various organs without causing a mass effect. Although $^{18}$F-FDG PET is a powerful imaging tool in lymphoma, the usefulness of $^{18}$F-FDG PET in the assessment of IVLBCL is still controversial. $^{99m}$Tc-MIBI, a tumor imaging radiopharmaceutical with a different mechanism from that of $^{18}$F-FDG, has been reported to be also effective in lymphoma. However, there is nearly no report on the efficacy of $^{99m}$Tc-MIBI in the assessment of IVLBCL. We present one case of IVLBCL that showed $^{99m}$Tc-MIBI accumulation in the involved bone marrow as an incidental finding, which was discrepant from that of $^{18}$F-FDG PET.

The objective of this study were to investigate the effects of culture media and additives on the development of bovine in vitro matured(IVM) and in vitro fertilized(IVF) oocytes. In experiment 1, bovine oocytes were cultured in droplets of TC 199 supplemented with 10% fetal bovine serum(FBS) with or without hormones (5$\mu\textrm{g}$/ml FSH, 5$\mu\textrm{g}$/ml LH, 1$\mu\textrm{g}$/ml E2). Cleavage rates of embryos cultured for 40~44hrs after IVF were higher when embryos were cultured in TC 199 supplemented hormones (68.1%, 921/35) than without hormones (52.7%, 77/146), but the percentages of development beyond morulae stage were not difference (20.7%, 19.4%). In experiment 2, the effects of various media such as TC 199, synthetic oviduct fluid(SOF), CR1aa with different energy source (fatal bovine serum, FBS; bovine serum albumin, BSA) on developmental capacity of IVM/IVF bovine embryos were investigated. The developmental rates into morulae and blastocysts were 27.1, 10.7, 6.3 and 0%, respecitvely, in CR1aa plus 3mg/ml BSA, SOF plus 10% FBS, TC 199 plus 10% FBS, SOF plus 3mg/ml BSA. In experiment 3, the comparisons of bovine embryos developed to morulae and blastocysts in different culture media (TC 199, SOF, CR1aa, Menezo's B2) were investigated. The developmental capacity beyond morulae stage were 32.9, 26.6, 11.1 and 7.1%, respectively, in Menezo's B2 plus BSA, CR1aa plus BSA, SOF plus BSA, TC 199 plus FBS medium. The cell numbers of the blastocyst were not different in different cultrue media. In experiment 4, bovine embryos were co-cultured with vobine oviduct epithelial cells(BOEC) in TC 199 plus FBS, SOF plus BSA, CR1aa plus BSA, Menezo's B2 plus BSA. The morula and blastocyst rates were 44.7, 32.9, 26.0 and 23.3%, respectively, in CR1aa TC 199, SOF, and Menezo's B2 medium. The cell numbers of the blastocyst were similar to those of blastocyst developed in different culture media.

We have investigated the magnetic properties and the electronic structures of Tc half-monolayer (0.5-ML) on Pd(001) using the full-potential linearized augmented plane wave(FLAPW) energy band method. We calculated the total energies for ferromagnetic and paramagnetic states to determine the stable magnetic state. The calculated results show that the total energy of the ferromagnetic state is lower than that of the paramagnetic one. The overlayer Tc 0.5-ML has considerably large magnetic moment $(2.09\;{\mu}_B)$, while the substrate Pd layers have been negatively polarized. The calculated density of states and total electrons inside the muffin-tin (MT) sphere are presented and discussed in relation with the magnetic properties.

To evaluate the hypolipidemic effects of Cheonggukjang (CGJ), which is frequently used in Korea similar to Natto in Japan and Douchi in China like a dairy product, boiled soybeans were fermented with two Bacillus strains, B. subtilis and B. licheniforms, isolated from rice straw and their antihyperlipidemic effects of their products were investigated. Treatment with the CGJs significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels and increased HDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. The treatment of non-fermented soybeans alone also reduced blood TG and TC levels, but not significantly. Feeding the CGJs significantly lowered high blood TG and TC levels as well as body and epididymal mass weights in hyperlipidemic mice induced by the long-term feeding of a high-fat diet that increased blood HDL cholesterol levels. The B. subtilis-fermented CGJ products more potently reduced TG and TC levels, although the differences between the starters were not significant. These finding suggest that CGJ products may be effective as hypolipidemic foods by the synergistic interaction of soy and Bacillus strains.

Tetracycline hydrochloride (TC) caused 100%, 50% and 20% mortality rates among rats injected with 40 mg, 30 mg and 20 mg/100g. b.w. respectively; while the morta]ity rates were decreased to 50%, 20% and 10% when Panax ginseng (2 mg/100g. b.w.) injected with TC during 72 hrs. post-injection. Subacute-toxicity study demonstrated that TC caused severe hepato-nephrotoxicity (demonstrated by biochemical analysis of serum including: transferases , alkaline phosphatase, total protein, glucose, cholesterol urea and creatinine) in rats injected i.p. with 10 mg and 5 mg/100g. b.w. for 7 days of daily injection . These signes of toxicity were greatly diminished by P. ginseng addition to TC doses.

Beef, pork and chicken on the market were analyzed for determination of tetracyclines residue and decomposition of tetracyclines by heating were studied. The content of oxytetracycline was trace in chicken A, 0.09 mg/kg in C and trace in beef C, pork A and B, but in the other samples was not detected oxytetracycline. Chlortetracycline residue was 0.14, 0.02 and 0.01 mg/kg in chicken A, C and beef B respectively. In HPLC analysis, two peaks of 8.1 and 9.0 min of retention time were found from beef and pork and expected to be component of meat, and because of same retention time, the one of 9.0 min interrupted determination of tetracycline. But those were not found in chicken, therefore the residue was 0.01 mg/kg in sample A. The residue were degradated rapidly by heating of roast, but slightly by that of boiling.
