The purpose of this study was to investigate the effects of dill on the quality characteristics of tomato sauce during 60 days of storage. As storage time increased, the pH stays between 4.10-4.22 on all additives. The lowest pH appeared on a 0% dill added sample during the storage period, except at 45 or 60 days of storage. The more dill was added, the less sugar appeared, and this was generally consistent across other samples. As storage times increased, the sugar content showed a tendency to decrease in all additives. Salinity turned out to be between 0.90-1.48 among all of the additives. For the L-value, the more dill was added, the less the L-value decreased, and this was consistent across all the samples. As the storage period increased, the L-value showed a tendency to decrease in all samples. The more dill was added, the more the a-value showed a tendency to decrease. The b-value showed a tendency to decline the more dill was added. Also, as storage time increased, the b-value decreased in all samples. Viscosity showed a tendency to increase in all samples the more dill was added. The reducing sugar content was kept between 44.83-55.38. A sensory evaluation was performed by 15 professional panelists with scoring tests for color, flavor, taste, aftertaste, viscosity, and overall acceptability. The tomato sauce with 2% dill showed the best score in the color, flavor, and overall acceptability. From the above results, the data suggests that an addition of 2% fresh dill to tomato sauce is recommended for commercial use.

The purpose of this paper is to classify all compact manifolds modeled on the 4-dimensional solvable Lie group $Sol_1^4$, and more generally, the crystallographic groups of $Sol_1^4$. The maximal compact subgroup of Isom($Sol_1^4$) is $D_4={\mathbb{Z}}_4{\rtimes}{\mathbb{Z}}_2$. We shall exhibit an infra-solvmanifold of $Sol_1^4$ whose holonomy is $D_4$. This implies that all possible holonomy groups do occur; the trivial group, ${\mathbb{Z}}_2$ (5 families), ${\mathbb{Z}}_4$, ${\mathbb{Z}}_2{\times}{\mathbb{Z}}_2$ (5 families), and ${\mathbb{Z}}_4{\rtimes}{\mathbb{Z}}_2$ (2 families).

This study aimed to evaluate the marginal microleakage of Class V cavities of All-bond 2 (Wet - bonding system), Gluma (Adhesion of resin to exposed collagen fibers), and Scotchbond Multi-purpose(Mild Etching System). Hundred extracted human teeth divided into a control and three experimental groups consisting of eight teeth. The experimental group was further subdivided into All- bond2, Gluma and Scotchbond MP groups, Vitrebond served as the control. The positive control group consisted of specimens filled with resin and with no etching, primer and bonding procesure. Polished specimens underwent temperature changed from $5^{\circ}C$ to $55^{\circ}C$ a thousand times. After thermocycling, speciemens were placed in 2 % methylene blue dye solution for 24 hours in an incubator set at $37^{\circ}C$. The teeth were sectioned buccolingually and the degree of dye penetration was observed with a stereomicroscoped(*20). The following results were obtained. 1. Both the control and the experimental group showed a lower degree of dye penetration on enamel than on dentin margins(p<0.05) 2. Gluma exhibited a statistically significant lower degree of dye penetration than All-bond 2 on enamel margins(p<0.05) Scotchbond MP also exhibited a lower degree of dye penetration than All-bone 2 but was no statistically significant. Gluma and Scotchbond MP exhibited a similar degree of dye penetration. 3. The degree of dye penetration of All-bond 2, Gluma and Scotch bond MP showed no statistically singnificance on enamel margins but was significantly lower than in the control using Vitrebond. 4. All-bond 2 exhibited a statistically significant lower degree of dye penetration than Gluma on dentin margins. All- bond 2 and Scotchbond MP showed a similar degree of dye penetration. 5. The degree of dye penetration of All-bond 2, Gluma and Scotchbond MP showed no statistically significance on dentin margins. There was neither a statistical significance with the control.

Purpose: To report the clinical results and efficacies of one stage reverse lateral supramalleolar adipofascial flap for soft tissue reconstruction of the foot and ankle joint. Material and Methods: We performed 5 cases of one stage reverse lateral supramalleolar adipofascial flap from Jan 2005 to Sept 2005. All patients were males and mean age was 50(36~59) years old. The causes of soft tissue defects were 1 diabetic foot, 2 crushing injuries of the foot, 1 open fracture of the calcaneus, and 1 chronic osteomyelitis of the medial cuneiform bone. Average size of the flap was 3.6(3~4)${\times}$4.6(4~6) cm. All flaps were harvested as adipofascial flap and were performed with the split-thickness skin grafts (STSG) above the flaps simultaneously. Results: All flap survived completely and good taking of STSG on the flap was achieved in all cases. There were no venous congestion and marginal necrosis of the flap. In diabetic foot case, wound was healed at 4 weeks after surgery due to wound infection. There was no contracture on the grafted sites. Ankle and toe motion were not restricted at last follow up. All patients did not have difficulty in wearing shoes. Conclusion: The reverse lateral supramalleolar adipofascial flap and STSG offers a valuable option for repair of exposure of the tendon and bone around the ankle and foot. Also one stage procedure with STSG can give more advantages than second stage with FTSG, such as good and fast take-up, early ambulation and physical therapy, and good functional result.

An in vitro experiment was conducted to examine the effects of defaunation (removal of protozoa) on ruminal fermentation characteristics, $CH_4$ production and degradation by rumen microbes when incubated with cereal grains (corn, wheat and rye). Sodium lauryl sulfate as a defaunation reagent was added into the culture solution at a concentration of 0.000375 g/ml, and incubated anaerobically for up to 12 h at $39^{\circ}C$. Following defaunation, live protozoa in the culture solution were rarely observed by microscopic examination. A difference in pH was found among grains regardless of defaunation at all incubation times (p<0.01 to 0.001). Defaunation significantly decreased pH at 12 h (p<0.05) when rumen fluid was incubated with grains. Ammonia-N concentration was increased by defaunation for all grains at 6 h (p<0.05) and 12 h (p<0.05) incubation times. Total VFA concentration was increased by defaunation at 6 h (p<0.05) and 12 h (p<0.01) for all grains. Meanwhile, defaunation decreased acetate and butyrate proportions at 6 h (p<0.05, p<0.01) and 12 h (p<0.01, p<0.001), but increased the propionate proportion at 3 h, 6 h and 12 h incubation (p<0.01 to 0.001) for all grains. Defaunation increased in vitro effective degradability of DM (p<0.05). Production of total gas and $CO_2$ was decreased by defaunation for all grains at 1 h (p<0.05, p<0.05) and then increased at 6 h (p<0.05, p<0.05) and 12 h (p<0.05, p<0.05). $CH_4$ production was higher from faunation than from defaunation at all incubation times (p<0.05).

The present studies were designed to observe the effects of both dietary fat levels and P/S ratio on lipid components in plasma and tissues of young rats when cholesterol was supplemented at 1%(w/w) to four dietary groups providing total fat as 10%( LF ) or 45% ( HF ) of calories and P/S ratio as 0.2 or 4.0, Low Fat-0.2 : Low Fat-4.0 : High Fat-0.2 : High Fat-4.0. Plasma total cholesterol was increased almost to the same level in all dietary groups after the cholesterol supplement but the value of HF -0.2 was slightly higher than that of LF -0.2. Plasma TG was also increased in all dietary groups when cholesterol was supplemented but was more significantly increased in LF group than in HF group. HDL-cholesterol was slightly increased by cholesterol supplement but there was no effect by the total dietary fat level of previous diet. However, plasma HDL-cholesterol, total cholesterol and TG levels were slightly reduced in high fat diet of P/S 4.0. Total cholesterol per g -liver was higher in HF group than in LF group before and after cholesterol supplement even though it was increased more in LF group with cholesterol addition. Liver cholesterol was also higher in rats fed diets of P/S 4.0 at high fat level before and after cholesterol supplement. In contrast, total cholesterol per g-muscle was reduced by cholesterol supplement in all groups and it was significantly higher in LF than in HF. There was no significant effect in liver TG by total fat level and P/S ratio when cholesterol was supplemented. Muscle TG was lowered in all groups by cholesterol supplement but no effect by total fat level and P/S ratio.
