6.Investigation of the Possibility of Applying Protection Motivation Theory in Consumers’ Changes by Fipronil Egg Contamination
Journal of the Korean Dietetic Association 2020;26(4):278-288
This study examined the effects of response-facilitating factors(Food-related Knowledge, Response-Efficacy, and Self-Efficacy) and response-inhibiting factors(Severity, Vulnerability, and Consumer Stress) on the consumer’ behavior intention based on protection motivation theory, which explains the behavioral change to protect oneself. This study was conducted to reduce the customers’ concerns regarding food safety accidents and introduce ways to make them more interested in food safety. A sample of 225 adults over 19 years of age was collected in February 2018 through a self-administered questionnaire. The results of the cognitive mediation process of protective motivation theory showed that the consumers’ knowledge and self-efficacy which are response-facilitating factors, positively influence the behavioral intention. Severity and consumer stress were response-inhibiting factors. On the other hand, response-efficacy, which is a response-facilitating factor, and vulnerability, which is a response-inhibiting factor, did not influence the behavioral intention. Therefore, severity and consumer stress are response-inhibiting factors. The results were analyzed as a result of a behavioral change to protect oneself from food safety accidents. The applicability of the theory of protection motivation on the topic of food safety was also confirmed.
7.Unusual bone regeneration following resective surgery and decontamination of peri-implantitis: a 6-year follow-up
Journal of Dental Rehabilitation and Applied Science 2022;38(3):171-177
Peri-implantitis is an inflammatory lesion of the periodontium surrounding an endosseous implant, with progressive loss of the supporting peri-implant bone. The main purposes of treatment for peri-implantitis due to biological factors include addressing the inflammation and restoring a healthy but reduced periodontium around the implant, similar to the treatment of periodontitis in natural teeth. The proposed treatment protocol includes surgical treatment, mainly resective surgery, after non-surgical treatment such as oral hygiene instructions, mechanical cleansing of the fixture, and general or topical antiseptic or antibiotic application according to the extent of inflammation. In this article, we present a 6-year follow-up case showing unusual marginal bone regeneration after resective surgery and decontamination of an implant surface for the treatment of peri-implantitis and discuss the possible reasons.

The effects of intravenous Verapamil administration on ventricular function were evaluated using grated radionuclide ventriculography in 15 patients with essential hypertension. Verapamil(0.1mg/kg) was injected as a bolus for 2 minutes followed by an infusion of 0.007mg/kg/min. Heart rate, blood pressure, ejection fraction, peak ejection rate, total filling time, and prak filling rate were assessed before and after Verapamil administration. The results were was as follows ; 1) Verapamil administration increased heart rate from 63+/-5 to 75+/-9 beats/min(p<0.01) and reduced systolic and diastolic blood pressure from 156+/-17/99+/-6mmHg to 139+/-16/88+/-6mmHg(p<0.01). 2) Ejection fraction, peak ejection rate, and total filling time were not changed significantly after Verapamil injection. 3) Right and left ventricular peak filling rate increased significantly only in patients in whom it was subnormal in the basal study) from 1.6+/-0.4 to 2.3+/-1.1 end-diastolic volumes/s, p<0.05 and from 2.5+/-0.6 to 3.1+/-0.8 end-diastolic volumes/s, p<0.05, respectively). In conclusion, it was found that intravenous Verapamil administration enhances ventricular diatolic function in patients with essential hypertension.

PURPOSE: The transobturator adjustable tape (TOA) sling operation is a new procedure that allows for the adjustment of tension after surgical intervention, thus permitting correction of postoperative incontinence or obstruction. The aim of this study was to compare the efficacy and safety of TOA with that of the transobturator tape (TOT) procedure. MATERIALS AND METHODS: Between 2008 and 2009, women with stress urinary incontinence (SUI) underwent TOT (n=63) or TOA (n=40). The preoperative evaluation included history taking, physical examination, voiding diary, stress and 1-hour pad tests, and a comprehensive urodynamic examination. Postoperative evaluation was performed at the 1-week and 3-month postoperative follow-up visits. RESULTS: The overall cure rate was 90.0% for the TOA group and 85.7% for the TOT group. The rate of satisfaction was higher in the TOA group than in the TOT group (95.0% vs. 85.6%). Four patients in the TOA group needed reduced tension as the result of urinary obstruction. The tension of the mesh was tightened in 1 patient because of a certain degree of continuing incontinence. The residual urine volume was significantly lower in the TOA group than in the TOT group (7.8 ml vs. 43 ml, p=0.01). CONCLUSIONS: TOA allowed postoperative readjustment for a number of days after surgical intervention, which allowed for good short-term treatment outcomes. These data suggest that better subjective and objective results and residual urine volume can be obtained in the TOA group than those achieved with the traditional non-adjustable mesh and without significant postoperative complications.

STUDY DESIGN: Experimental investigation in vitro. OBJECTIVES: To evaluate the relationship between the degeneration of intervertebral disc cells, and low back pain induced by degeneration of intervertebral disc cells and increases in use of proinflammatory mediators via nicotine stimulation. SUMMARY OF LITERATURE REVIEW: Smoking is a leading cause of degeneration of intervertebral disc cells and low back pain. According to the existing literature, nicotine, one of the main ingredients in cigarettes, causes the degeneration of intervertebral disk cells including decrease of glycoprotein through generation of carboxy-hemoglobin, vasoconstriction, and disability of fibrinolysis and changes of metabolism of nucleus pulposus cells. MATERIALS AND METHODS: Annulus fibrosus of intervertebral disc and knee joint cartilage were collected from pigs; these cells were acquired by gradual enzyme decomposition. Using Trypan blue, concentration and survival rate of cells were examined; cells were inserted on alginate beads for tertiary cultivation. Nicotine was then applied at 0, 50, 100, 200 and 300 nM, respectively, and the samples were cultivated for three, six and nine days, respectively. After collecting culture fluid, it was measured for interleukin(IL)-1beta, IL-6 and IL-8 with the ELISA Test. DNA of cells used for cultivation was quantitated and the amount of the resulting proinflammatory mediator was normalized. The results were then compared with the result of same study on cartilage of porcine knee joints. RESULTS: For changes of the inflammatory mediator based on the concentration of nicotine, in nicotine stimulation with low concentration of 50 nM and the control group, there was no significant change, while transient increases of inflammatory mediator showed in nicotine stimulation with concentrations of 100, 200 nM, respectively. There was not a significant increase of IL-1beta observed in all nicotine stimulation groups; these were the same results in porcine cartilage study. The level of IL-6 in 200, 300 nM nicotine concentration showed significant increases, respectively. The level of IL-8 in high dose nicotine stimulation groups also showed significant increases of DNA on the sixth day. And in porcine cartilage study group, significant changes were observed in 200, 300 nM, but the absolute value was lower than that of annulus fibrous cells group. CONCLUSION: Inflammatory mediators such as IL-6 and IL-8 increased as the result of tertiary cultivation of annulus fibrosus cells of porcine intervertebral disk and nicotine stimulation. It is believed that the cells of the disc annulus are more sensitive than articular chondrocytes to nicotine stimulation. This may be the focus of future long-term studies effects of nicotine other inflammatory cytokines.
