This study proves that syringe reuse of automated injection system entails a risk of contrast media reflux and saline solution contamination which are pumped by a piston into the patients' venous cannula in the dynamic MR images, we will be aware of the serious problem. To quantify the contrast media contamination effect on the saline solution, identical volume of the saline solution was collected before and after the contrast injection to the patients' venous cannula following T1 weighted image scanning to verify whether signal intensities differences are observed. The signal intensity of saline solution after the contrast injection was significantly higher than that of saline before injection by 523.43%. This result is due to the backflow that contaminates the saline solution on the opposite side when the contrast agent is injected. In conclusion, the syringe used to inject contrast medium. causes cross-contamination due to contrast reflux. Therefore, even if the same patient's examination is used for quantitative analysis, the error should be avoided by changing the acquisition sequence or replacing the syringe.

This study was conducted to investigate the effect of oral administering kefir on blood glucose levels in diabetic mice. Kefir($10\;m\ell/kg$ body weight) was orally administered to diabetic mice twice daily for 45 days. Diabetic mice fed saline or 10% skim milk were used as a control. No significant difference in feed intake and weight gain were observed among the treatments. Compared to the saline-fed or skim milk-fed group, blood glucose in the kefir-fed group decreased significantly at 45 days(p<0.05). At 45 days, serum triglyceride and non-esterified fatty acid concentrations in diabetic mice fed kefir decreased significantly compared to those of the saline and skim milk groups(p<0.05). Both high density lipoprotein and low density lipoprotein concentrations were not significantly different among the three treatment groups. In conclusion, the symptoms of diabetic mice improved when kefir was fed for >45 days.

Purpose: The aim of this study was to confirm if Laser-treated implants were soaked in 0.9% NaCl solution for 2 weeks could increase the surface hydrophilicity, and the Remoal Torque of each implant that inserted in rabbit tibia for initial healing period of 10 days. Materials and methods: Twenty machined titanium surface screws were produced with a diameter 3 mm, length 8 mm. Ten screws had their surface treated with a laser only (laser treated group), and the other 10 were soaked in saline for 2 weeks after surface treatment with a laser (laser treated + saline soaked group). Implants were inserted in rabbit tibia (ten adult New Zealand white rabbits), and the RTQ of each implant was measured after 10 days. The wettability among implants was compared by measuring the contact angle. Surface composition and surface topography were analyzed. Results: After 10 days, the laser treat + soaking group implants had a significantly higher mean RTQ than the laser treated implants (P = .002, < .05). There were no significant morphological differences between groups, and no remarkable differences were found between the two groups in the SEM analysis. Conclusion: Saline soaking implants is expected to produce excellent RTQ and surface analysis results.

In order to manufacture the low salt and functional Kochujang, salt amount was reduced to 6% and chitosan was added to 0.25% to the Kochujang preparation. The contents of ash, moisture, crude fat and crude protein in Kochujang were not affected by the reduced salt concentration and chitosan addition. pH and titratable acidity were not significantly changed by the addition of chitosan. Ethanol content was higher in 6% salt Kochujang tan in 9% salt Kochujang and decreased by the addition of chitosan. Reducing sugar content was lower in 6% salt Kochujang than in 9% salt Kochujang and increased by chitosan addition. $\alpha$-Amylase activity was slightly inhibited by the addition of chitosan, however, $\beta$-amylase, acidic protease and neutral protease activities were not affected. Amino nitrogen and ammonia nitrogen contents were higher in 6% salt Kochujang than in 9% salt Kochujang, but ammonia nitrogen production was significantly decreased by chitosan addition. Also the growth of bacteria and yeasts were slightly inhibited by the addition of chitosan. From the above results we concluded that 0.25% chitosan was the good concentration to prepare the low salt and functional Kochujang.

As a part of efforts to elucidate the influence of Panax Ginseng upon nucleic acid content of various tissues, a study was carried out which measured RNA and DNA contents of bone marrow following administration of ginseng. Thirty male rats $(body\;weight:\;180{\sim}230\;gm)$ were equally divided into a ginseng and a saline group. Once a day for 5 days they received subcutaneously 0.5 m1/100 gm body weight ginseng extract solution (4 mg of ginseng alcohol extract in 1 ml of saline), and the same amount of saline, respectively. On the 5th experimental day, all animals were sacrificed 2 hours after the last medication and the bone marrow of one femur was removed. RNA and DNA contents of the bone marrow were measured using the chemical method of Schmidt Thannhauser-Schneider. Results obtained were as follows 1. RNA and DNA contents of the bone r arrow were significantly higher in the ginseng group than in the saline group. 2. RNA/DNA ratio of the bone marrow was also much higher in the ginseng group than in the saline group. The ginseng is inferred to augment RNA and DA contents, and also raise RNA/DNA ratio of the bone marrow in rats.
