A replication initiation gene was identified and its nucleotide sequence has been determined from a 3.8 kb, chloramphenicol acethyltransferase conferring R-plasmid pSBK203 of Staphylococcus aures. Location of the replication related region of pSBK 203 was determined by interuption with pUC 119 at XBaI and MspI sites which resulted in inactivation of replication in Bacilius subtilis. Base sequence of this region revealed on open reading frame of 942 base pairs, which encoded a 314 amino acid protein. Base sequence homology with other rep of pT181 family plasmids such as pT181, pC221, pC223, pS194, pU112, and pCW7 was ranged from 78% to 97% and the predicted amino acid sequence homology was from 72% to 95%.

The present experiment was performed in order to know the therapeutic effect of laserpuncture and aquapuncture with methionine on recovery in artificially induced hepatic damaged rats by carbon tetrachloride. The animals were divided into control, laserpuncture and aquapuncture groups. The changes of serum enzyme activities(ALT and AST), serum total protein contents, protein fractions(ALB and GLB) and A/G ratio were examined before and after application of laserpuncture and aquapuncture. In change of serum ALT activity, recovery with treatment in laser and aquapuncture groups was more rapid than that of control. The significant decreased value was shown on 3rd(P < 0.05) and 7th day(P < 0.01) after treatment in laserpuncture group and on 7th day(P < 0.05) after treatment in aquapuncture group. In addition, significance was detected on 2nd day(P < 0.05) between laserpuncture and aquapuncture groups. In change of serum AST activity, recovery with treatment in laserpuncture and aquapuncture groups was more rapid than that of control. The significant lower values on 7th day(P<0.01) in aquapuncture groups. In addition, significant low value was detected on 7th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture group. The change of serum TP contents showed similar pattern in control, laser and aquapuncture groups. The significances were detected on 7th day(P < 0.05) in both experimental groups. In addition, significant high value was detected on 2nd day(P < 0.05) in laserpuncture group comparing with that of aquapuncture group. The change of serum ALB content with treatment in laser and aquapuncture groups was more rapid than that of control. The significant high value was shown on 2nd(P < 0.01), 5th(P < 0.05) and on 7th day(P < 0.01) in laserpuncture group. In addition, significant high value was detected on 3rd day(P<0.01) only in aquapuncture group comparing with laserpuncture group. The change of serum GLB content showed similar pattern among groups. The significant low values were detected on 2nd day(P < 0.05) in aquapuncture group. In addition significant high value was detected on 5th day(P < 0.01) only in laserpuncture group comparing with that of aquapuncture group. In change of A/G ratio laser and aquapuncture groups showed higher values than that of control. The significant high values were detected on 1st day(P < 0.Of) and 2nd day(P < 0.05) in laserpuncture group, and on 1st day(P < 0.05) and 2nd day(P < 0.01) in aquapuncture group. In addition, significant high value was detected on 5th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture. Considering above findings collectively, it was considered that both laserpuncture and aquapuncture were effective; aquapuncture was more effective than laserpuncture for recovery of hepatic damage.

The amount and type of dietary protein that effects affect bone mineral loss after menopause and different dietary patterns may influence anthropometric measurements, biochemical values, and bone metabolism. Objective : Our objective was to investigate bone metabolism and chronic disease factors in two different dietary patterns. Design: The sample consisted of 40 lacto-ove-vegetarians(LOV) and 49 omnivores aged from 47 to 85 years in good condition without any medical problems. Results : The average energy intake of LOV was 1414.0kcal and omnivores, 1403.2kcal. The difference between means was not statistically significant. The differences of means of body weight and BMI between the two groups were not significant but the systolic blood pressure of LOV group was significantly lower than omniovores(p<0.05). The values of serum cholesterol(p<0.05) and glucose(p<0.05) of LOV were signifcantly lower than that of omnivores. The serum albumin level(p<0.01) of LOV was lower than it'scounterpart but in a normal range. The intake of crude fiber(p<0.05) of LOV group was significantly higher. The urinary pH of LOV was 7.4 and that of omnivores was 6.3(p<0.001). Plant calcium(p>0.05) and plant iron(p<0.001) had positive correlations with the uninary pH but animal protein(p>0.05) and animal iron(p>0.05) had negative correlations with the urinary pH. The level of urinary biochemical marker of bone resorption, deoxypyridinoline(DPD) of LOV was significantly lower than the other group(p>0.05). The T-scores of bone mineral density for the two sites in the two groups were not significantly different. Conclusions : The DPD level and urinary pH value of LOV were more desirable for the bone metabolism that the omnivores. The diet of LOV had lower risk factors of chronic diseases than the other group.

This study was conducted to estimate the effect of different cutting lengths on fermentation characteristics and aerobic stability of whole crop rice (WCR) silage. The WCR was harvested at the yellow ripe stage (43.7%, DM), and then cut at 5 (R05), 10 (R10), and 20 cm (R20) of the theoretical length of cut with no cut WCR (R60). Each forage was ensiled into 20 L mini bucket silo (5 kg) for 150 days in quadruplicates. The cutting lengths were not affected the chemical compositions of WCR silage (p > 0.05). The pH (p < 0.001) and concentration of ammonia-N (p = 0.022) in WCR silage were increased linearly with the increase of cutting length. The concentration of lactate had quadratic effect (p = 0.007), which was highest in R20 silage (p < 0.05). The concentration of acetate was increased linearly (p = 0.014), but the concentration of butyrate was decreased linearly (p = 0.033). The lactic acid bacteria count was decreased linearly (p = 0.017), and yeast count had quadratic effect (p = 0.009), which was the highest in R20 silage (p < 0.05). Aerobic stability had strong quadratic effect (p < 0.001), which was the highest in R20 silage (p < 0.05). In conclusion, R60 silage had highest pH by a linear increase of ammonia-N concentration and led to low aerobic stability. While R20 silage had the lowest pH by high lactate concentration and led to high aerobic stability.

This study investigated the growth and metabolic characteristics of Arthrospira platensis (A. platensis) according to pH, which has an alkaline optimal pH. The intake of inorganic carbon was expected to be the highest at the optimum pH 9, but it was different from the expectation, so the cause of the excessive intake of inorganic carbon at pH 7 was investigated. We tried to verify the triacylglycerol (TAG) synthesis metabolic mechanism because it was assumedthat the inorganic carbon intake of A. platensis according to pH is closely related to lipid production inside the cell. To verify this, the effects of pH on inorganic carbon intake were examined through lipid analysis inthe cell of A. platensis according to pH. As a result, in the case of the effect of inorganic carbon intake of A. platensis according to pH on TAG content, pH 9 and pH 11 showed no significant difference in TAG content, but at pH 7, it was two times higher compared to pH 9 and pH 11. It was assumed that the reason why A. platensis excessively consumed inorganic carbon at pH 7 was because itincreased the TAG content in proportion to the intake of inorganic carbon to protect cells from external pH stress. In addition, it is considered that the TAG content produced in proportion to the intake of inorganic carbon is because acetyl-CoA produced in the Calvin cycle is required for the synthesis of TAG.

The purpose of this study was to identify the sleep/activity patterns of neonates and to provide a baseline data for the development effective mother-infant relationship. Subjects of this study were 36 newborns aged 1-21 days and stayed in Postpartum Care Center in Taejon during the period of October 28th, 1999 to February 10th, 2000. The data were collected using NCASA developed by Barnard et al. and were analyzed with SPSS 7.5 for window program. The results of this study were as follows: 1. An average day sleep of neonates was 8.0 hours, night sleep was 3.6 hours, and total sleep was 11.6 hours. A longest period of day sleep was 3.8 hours and a longest period of night sleep was 3.4 hours. The regularity of day sleep was 22.1%, night sleep was 23.3%, and total was 22.1%. 2. The frequency of daytime feeding was 6.9, nighttime fee ding was 3.4, resulting in total of 10.3. The regularity of feeding was 37.4%, and the frequency of night awakening was 2.4. 3. Associations among variables related to neonate's sleep/activity records were as follows : - The regularity of total sleep was positively correlated with the frequencies of day sleep(r=.57, P=.00), night sleep (r=.40, P=.01), and total sleep(r=.65, P=.00). - The frequency of total feeding was negatively correlated with the frequencies of day sleep(r=-.29, P=.04), night sleep(r=-.39, P=.02), and total sleep(r=-.42, P=.00), as well as longest day sleep(r=-.50, P=.00). - The regularity of feeding was negatively correlated with the frequency of night sleep(r=-.35, P=.02), longest period of day sleep(r=-.32, P=.04), and longest period of night sleep(r=-.30. P=.04), whereas positively correlated with frequencies of daytime feeding (r=.29, P=.02) and nighttime feeding (r=.32, P=.05). - The frequency of night awakening was negatively correlated with amount of night sleep(r=-.39, P=.02) and frequency of daytime feeding(r=-.42, P=.01) while positively correlated with frequencies of nighttime feeding(r=.68, P=.00) and total feeding(r=.50, P=.00). 4. Although there was no statistical significant difference between sleep pattern and infant's age, following tendency was noted: - As baby gets older, total amount of sleep and longest period of day sleep decreased while longest period of night sleep increased. - As baby gets older, the regularity of day sleep decreased while the regularity of night sleep and total sleep slightly increased. - The frequencies of daytime and total feedings increased while the frequency of nighttime feeding decreased. In conclusion, the author found that the neonates of this study showed less amount of sleep, more night awakening, and more night time feedings than NCAST sample. There was a certain sleep/activity pattern existed: If babies were fed more frequently, daytime or nighttime sleeping hours became shorter, and if babies had longer daytime sleep, frequent nighttime awakenings were noted. This pattern illustrated the significant influence of feeding and sleep periods on each other. Awakening in the night is natural and normal patterns in the newborn period. The result of this study will provide information to parents about what to expect their infants.
