The most common local cause of active gingival bleeding is the vessel engorgement and erosion by severe inflammation. Abnormal gingival bleeding is also associated with the systemic disturbances. Hemorrhagic disorders in which abnormal gingival bleeding is encountered include the following: vascular abnormalities (vitamin C deficiency or allergy), platelet disorders, hypoprothrombinemia (vitamin K deficiency resulting from liver disease), and other coagulation defects (hemophilia, leukemia). There are many conventional methods for gingival bleeding control, such as, direct pressure, electrocoagulation, direct suture, drainage, application of hemostatic agents and crushing and packing. If the active continuous gingival bleeding is not stopped in spite of the application of all conventional bleeding control methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency dental care. This is a case report of active gingival bleeding care via dental crown removal and emergency primary endodontic drainage as a last method in liver cirrhosis patient with advanced periodontitis.

Purpose: The purpose of this present study was to develop and evaluate the psychometric properties of a needs scale for patients with cancer undergoing follow-up care (NS-C). Methods: A preliminary NS-C of 48 was derived from literature reviews and in-depth interviews with patients with cancer. Content validation of the items was established by oncology physicians and nurses. Each item was scored on a five-point Likert scale. The preliminary NS-C and Eastern Cooperative Oncology Group (ECOG) performance status questionnaires were administered to 873 patients with cancer recruited from three university hospitals. The data were analyzed using factor analysis, multidimensional scaling analysis, ANOVA, Pearson correlation coefficients, and Cronbach's alpha. Results: From the factor analysis, 25 significant items in six subscales were derived. The subscales were named physical symptoms, diet and exercise, support, relationship with health professionals, treatment/prognosis, and keeping mind under control. The NS-C also established item convergent and discriminant validity, and known-groups validity. Cronbach's alpha of the subscales ranged from .90 to .92. Conclusion: This study suggests that the NS-C is an easy, reliable and valid instrument to measure the needs of patients with cancer. Health professionals may use the NS-C for patients with cancer both in practice and research.

This study was to investigate serum triglyceride (TG), phospholipid (PL), and cholesterol concentrations after feeding the combined diets of prepared traditional Cheonggukjang (TC) or Cheonggukjang made from sword bean powder (CS), the feed, and high-fat cholesterols at certain ratio for 8 weeks in rats, and then confirmed the effects of the diets based on the changes in the tissues of livers, kidneys, and spleens. The serum TG concentrations were lower in CS group compared to that of in TC group. The increase of PL concentrations was greater in CS group than that of TC group. FChCS6 group (92% feed+2% cholesterol+6% CS) showed the lowest total-cholesterol (T-C), $60.1{\pm}8.5mg/dL$, indicating that CS was effective to lower the T-C. Both TG/PL and T-C/PL ratio tended to be decreased. As CS intake was effective in the reduction of low density lipoprotein-cholesterol level as well as the increase of high density lipoprotein-cholesterol level, it would be effective in the prevention of adult diseases and circulatory diseases. It was confirmed that there were no changes in organ appearance and tissues in the rats with CS intake. Therefore, CS intake showed superior functionalities than that of TC intake.

Recently, several generative models have emerged and are being used in various industries. Among them, Cycle GAN is still used in various fields such as style transfer, medical care and autonomous driving. In this paper, we propose two methods to improve the performance of these Cycle GAN model. The ReLU activation function previously used in the generator was changed to Leaky ReLU. And a new loss function is proposed that considers the semantic level rather than focusing only on the pixel level through the VGG feature extractor. The proposed model showed quality improvement on the test set in the art domain, and it can be expected to be applied to other domains in the future to improve performance.

Recent evidence suggests that many Oriental Medicinal prescriptions are effective in cancer patients as a supportive care. Oriental Medicinal herbs have been investigated extensively and are known to have multiple pharmacological effect. These herbs contain a variety of ingredients which may act synergistically to inhibit tumor cell division, to increase tumor cell death (apoptosis), and to increase the proportion of immune cells within tumor. Paljinhangahm-dan (Paljin) has been used to treat for cancer patients in Oriental Medicine for decades. The effects of aqueous extract of Paljin on the induction of apoptotic cell death were investigated in human leukemia cell lines (HL-60, Jurkat, Molt-4 and U937). The viability of leukemia cells was markedly decreased by Paljin in a dose-dependent manner. Paljin induced the apoptotic death of leukemia cells, which was characterized by the ladder-pattern DNA fragmentation, and chromatin condensation of the nuclei. Paljin digested Bid protein but did not affect Bcl-2 protein level and also, induced mitochondrial dysfunction disrupted as shown as the mitochondrial membrane potential. It activated caspase-9 and caspase-3. thereby resulted in cleavage of poly(ADP) ribose polymerase(PARP). These results indicate that Paljin induces apoptosis of human leukemia cells via activation of intrinsic caspase cascades with mitochondrial dysfunction.

The purpose of this study was to evaluate the tooth whitening efficacy of 2.9% hydrogen peroxide strip with primer gel of alkaline condition and containing metallic salts as catalyst in-vitro. Hydroxyapatite (HAP) disk was made by compressing and sintering 0.3 g of mixture of HAP powder and polyvinyl alcohol. This HAP disk was stained using modified Stookey's methods. Main bleaching materials were 2.9% hydrogen peroxide strips and the primer gel containing metallic salts as catalyst and pH controller. Stained HAP disks were allocated to each control or experimental groups by color grade. Stained HAP disks were treated for 30 minutes in $37^{\circ}C/80%$ incubator for wetting, then each primer gel according to control or each test group was spread and strips were attached. After 30 minutes for each group strips were detached and HAP disks were washed, dried then color was measured by colorimeter. Efficacy was evaluated by comparing ${\Delta}L$ values of HAP disks at baseline and after treated. Among some kinds of metallic salts for as catalyst, ferric chloride showed best improvement of efficacy and it was statistically significant (p<0.05) compared to control group. Evaluating whitening efficacy according to various pH of primer, efficacy using primer of alkaline condition was increased significantly (p<0.05) compared to control and primers of acidic or neutral conditions. Evaluating whitening efficacy for time course, efficacy of test group for 30 minutes was similar to that of control for 120 minutes. It can be concluded that 2.9% hydrogen peroxide strips using with primer of alkaline condition and containing ferric chloride showed significantly increased whitening efficacy compared to the case of strips only.
