It is a fact that there are recent increasing trends or incidence of the colorectal carcinoma among other colorectal diseases. In such trend, the early detection remain to be most important by the air contrast barium enema and total colonofiberscopy. There are several ways to prepare the colon for barium enema and colonofiberscopy which include several agents. The mechanical cleansing have been used most frequently since Brown's method was adapted to be most perfect for colon deansing. The ideal laxatives and enema solutions were limited to adequate dose, it's effectiveness, patient's diet and bowel habit, minimal side effect, low cost and simple to perform. In order to compare the effectiveness of various cleansing solutions, six experimental methods were formed as shown; 1. normal saline enema, 2. castor oil with normal saline enema, 3. castor oil with soap suds enema, 4. magnesium citrate with normal saline, 5. magnesium citrate with soap suds enema and 6. ingestion of Golyetly solution. The authors have compared and determined the degree of cleanness by an experienced endoscopist. The total number of patients was 247, age distribution was $43{\pm}15$ years old, and sex distribution was 133 males and 114 females. The grade I and II represented no difficulties at performing the colonofiberscopy, but grade ill and N had some difficulties, even unable to perform the colonofiberscopy. The effectiveness the cleansing agents, represented with grade I and II was 95.9% (47/49) in method 6, 93.2%(54/58) in method 2, 83.3%(30/33) in method 3, 70.0%(28/10) in method 5, 66.7%(16/24) in method i, and 45.7%(18/40) in method 4. Method 2 and 6 were the most effective in normal bowel habit patients. In constipated patients, method 6 was the most effective and all method except method 11 were effective in diarrhea patients. The degrees of less mucosal irritation by various bowel cleansing method were in the order of method 6(100%), 1(100%), 5(74%), 2(69%). In subjective symptoms and cleansing groups, abdominal distension, pain, nausea and vomiting were complained, and that's subject symptoms were in the order of method 3(88.9%), 6 (79.6%), 1(75%), 5(72.5%), 2(72.4%), 4(67.5%). In conclusion, we believe that the Golytely of the mechanical cleansing solution for colonofiberscopy was the most effective, but others depended on the patient's condition und bowel habit.

Electronic cleansing is an image post processing technique in which the tagged colonic content is subtracted from colon using CTC images. There are post processing artefacts, like: 1) soft tissue degradation; 2) incomplete cleansing; 3) misclassification of polyp due to pseudo enhanced voxels; and 4) pseudo soft tissue structures. The objective of the study was to subtract the tagged colonic content without losing the soft tissue structures. This paper proposes a novel adaptive method to solve the first three problems using a multi-step algorithm. It uses a new edge model-based method which involves colon segmentation, priori information of Hounsfield units (HU) of different colonic contents at specific tube voltages, subtracting the tagging materials, restoring the soft tissue structures based on selective HU, removing boundary between air-contrast, and applying a filter to clean minute particles due to improperly tagged endoluminal fluids which appear as noise. The main finding of the study was submerged soft tissue structures were absolutely preserved and the pseudo enhanced intensities were corrected without any artifact. The method was implemented with multithreading for parallel processing in a high performance computer. The technique was applied on a fecal tagged dataset (30 patients) where the tagging agent was not completely removed from colon. The results were then qualitatively validated by radiologists for any image processing artifacts.

Objectives : The researcher had investigated the efficacy of ginseng using Microneedle Therapy System (MTS) and confirmed the effect of ginseng Cold Process (CP) soap just before and after washing face. The purpose of this study was to find out what kind of effect appeared through a period of 6 weeks when environmental factors were involved using ginseng CP soap. Methods : The researcher selected 47 subjects, 37 as the experimental group and 10 as the control group. The researcher asked participants to wash their face twice a day in the morning and evening using ginseng CP soap, and the period was set for 6 weeks. The researcher had the people who selected as the control group use a commercially available foam cleanser. They performed a skin test before the start of the test, and the change status was continuously investigated 2 weeks, 4 weeks, and 6 weeks after using the soap. Results : In the case of T-zone oil, there was a significant decrease in the use of foam cleansing and ginseng CP soap, and in the case of pores and pigmentation, a significant decrease was observed only in the use of ginseng CP soap. In skin tone change, there was a significant effect in both the experimental group and the control group, but the significance was greatly increased in the case of ginseng CP soap compared to foam cleansing. Conclusions : Ginseng CP soap is considered to be a more suitable cleanser for skin care compared to foam cleansing.

Purpose: This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction. Methods: The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming $2{\ell}$ of PEG solution twice, or a whole-dose group(n=30), consuming $4{\ell}$ of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS. Results: The participants who did not completely consume $4{\ell}$ of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups. Conclusion: Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.

The aim of this study was to compare ultrasonography with video-otoscopy for the evalution of the external ear canal and the tympanum. Fifty dogs with clinical signs ot the bilateral ear diseases were examined using otoscopy under general anesthesia. Ultrasonographic examination was performed with an 11 MHz linear-arrary probe and a 6.5MHz convex probe, with the external ear canal filled with saline. Saline functioned as a contrast media and enhanced image quality of ultrasonography. The images of 100 ears before and after the ear cleansing were obtained at otoscopy and ultrasonography. On the video-otoscopic images, the tympanic membrane was identified in 59 ears before the ear cleansing and 91 ears after cleansing. On the ultrasonography, the tympanic membrane was detected in 98 ears before the ear cleansing and in all ears after cleansing. With these results, it was concluded that ultrasonography with infusing saline into the ear canal, could be a useful diagnostic procedure to identify the tympanic membrane in otitis dogs.

Background : Repeated dis/re-connection of implant abutment caused bone loss around implant fixtures due to the new formation of biologic width of the mucosal-implant barrier. The aim of this clinical study was to evaluate whether the repeated dis/re-connection of implant abutment cause bone loss clinically and the effect of cleansing methods on a bone loss during the early healing period. Methods : A total 50 implants were installed in 20 patients and repeated dis/re-connection of abutment was performed at the time of surgery and once per week for 12 weeks. 0.9% normal saline solution as group1 and 0.1% chlorhexidine solution as group 2 was used to clean abutments. All patients had radiographs taken at the placement of implant and 4, 8, and 12 weeks postoperatively. The data for bone loss around implant were analyzed. Results: The marginal bone loss at 12 weeks were $1.28{\pm}0.51mm$, $1,32{\pm}0,57mm$ in the mesial and distal sides in group1, $1.94{\pm}0.75mm$, $1.81{\pm}0.84mm$ in group 2, respectively. In view of marginal bone loss, there was not a significant statistical difference between groups. Conclusions : Repeated dis/re-connection of implant abutment may not cause marginal bone loss around implant fixture although limited samples and short-term observation period. In spite of more bone loss in group 2, there was no statistical significant difference between groups. In context of those results, the clinical significance of the repeated dis/re-connection of implant abutment and the cleansing method of abutments is debatable when it comes to marginal bone loss during early healing period.
