Objectives: The purpose of this study is to investigate the effect of Melandrii Herba (MH), Akebia Quinata Decaisne (AQ), and Tetrapanax Papyriferus (TP) on milk secretion and aquaporin (AQP) expression in lactating mice. Methods: For the experiment, the mice were divided into three groups, which were orally administered MH (2,720 mg/kg), TP (400 mg/kg) and AQ (2,800 mg/kg) extracts respectively for 3 weeks from Day 1 after the birth, compared with the control group (C group), which was administered distilled water. A group consisted of six infantile mice per postpartum mouse. For comparison with the C group, non-pregnant SKH-1 mice were used as the virgin group. Results: 1. When it comes to the immunohistochemical staining for prolactin receptors in the mammary glands, the AQ and MH groups showed a strong immune response to the secretory epithelial cells constituting the mammary alveoli, while the TP group represented a weaker immune response. 2. In the immunohistochemical staining for AQP in the mammary glands, AQP1 showed a strong immune response in the walls of capillaries and venules around the mammary alveoli, and AQP3 in the epithelial cells constituting the mammary alveoli, and AQP5 in some tissues between the mammary alveoli. AQP1 was expressed in the order of TP group>AQ group=C group>MH group, and AQP3 was MH group and AQ group>TP group=C group, and AQP5 was MH group>C group>AQ group and TP group. 3. In the Western blot, AQP1 was expressed in the order of TP group>AQ group>C group>MH group, and AQP3 was MH group>AQ group>C group>TP roup, and AQP5 was MH group>TP Group>C group>AQ group. All of AQP1, 3, 5 expression were significantly higher in the C group than in the Virgin group. Conclusions: The administration of Akebia Quinata Decaisne, Tetrapanax Papyriferus and Melandrii Herba have the effect of improving prolactin levels in postpartum mice and increasing the expression of prolactin receptor and AQPs in the mammary glands, suggesting that lactation might be enhanced by the development of the mammary glands.

BACKGROUND/OBJECTIVES: The study was performed to investigate health-related lifestyle, dietary habits, and depression according to exercise frequency to understand complex factors that affect effective health management. Thus, exercise frequency, health-related lifestyle, dietary habits, and depression were evaluated in college students in Seoul and Gyeonggi-do areas. SUBJECTS/METHODS: A survey was conducted on college students, aged 19-29, in Seoul and Gyeonggi-do areas from May 13 to May 31, 2020. A total of 594 questionnaires were collected and 566 (269 from males, 297 from females) were statistically analyzed, except 28 with incomplete responses. Collected data were analyzed using SPSS WIN 21.0 program. RESULTS: The sex distribution of the 3 groups according to exercise frequency was significantly different; the ratio of males in over 3 times/week group was significantly higher than those in 1-2 times/week group and no-exercise group (P < 0.001). The height (P < 0.001), weight (P < 0.001), and body mass index (P < 0.05) were significantly higher in over 3 times/week group compared to no-exercise group. The ratio of subjects who answered 'good' or 'very good' for subjective health condition was significantly high in the order of 'over 3 times/week' group (59.1%), '1-2 times/week' group (34.5%), and 'no-exercise' group (25.0%) (P < 0.001). The ratio for meal regularity was high as 56.6% in 'over 3 times/week' group and the ratio for irregular meals was significantly higher in 'no-exercise' group (67.2%) and '1-2 times/week' group (54.9%) (P < 0.001). Among questions on dietary habits, 'Eat meat, fish, egg or beans' (P < 0.01) and 'Eat fruit' (P < 0.01) were significantly higher in 'over 3 times/week' group compared to 'no-exercise' group. 'Drink more than 2 liters of water' (P < 0.001) was 0.70 in 'over 3 times/week' group, which was significantly higher than 0.54 in '1-2 times/week' group and 0.38 in 'no-exercise' group. Moderate depression and severe depression that need treatments were significantly lower in 'over 3 times/week' group (18.7%) compared to '1-2 times/week' group (26.0%) and 'no-exercise' group (29.7%) (P < 0.05). CONCLUSIONS: It is considered that combined intervention for exercise habits, proper dietary habits, and depression management is needed for effective health management.

Objective : We investigated whether Disability Evaluation (DE) situations influence patients' neuropsychological test performances and psychopathological characteristics and which variable play a role to establish an explanation model using statistical analysis. Methods : Patients were 536 (56.6%) brain-injured persons who met inclusion and exclusion criteria, classified into the DE group (DE; n = 300, 56.0%) and the non-DE group (NDE; n = 236, 44.0%) according to the neuropsychological testing's purpose. Next, we classified DE subjects into DE cluster 1 (DEC1; 91, 17.0%), DE cluster 2 (DEC2; 125; 23.3%), and DE cluster 3 (DEC3; 84, 15.7%) via two-step cluster analysis, to specify DE characteristics. All patients completed the K-WAIS, K-MAS, K-BNT, SCL-90-R, and MMPI. Results : In comparisons between DE and NDE, the DE group showed lower intelligence quotients and more severe psychopathologic symptoms, as evaluated by the SCL-90-R and MMPI, than the NDE group did. When comparing the intelligence among the DE groups and NDE group, DEC1 group performed worst on intelligence and memory and had most severe psychopathologic symptoms than the NDE group did. The DEC2 group showed modest performance increase over the DEC1 and DEC3, similar to the NDE group. Paradoxically, the DEC3 group performed better than the NDE group did on all variables. Conclusion : The DE group showed minimal "faking bad" patterns. When we divided the DE group into three groups, the DEC1 group showed typical malingering patterns, the DEC2 group showed passive malingering patterns, and the DEC3 group suggested denial of symptoms and resistance to treatment.

Hepatic disease has been noted and reported for involvement various detrimental factors. Among many detrimental injury factors, alcohol has been noted for hepatitis, fatty liver, fibrosis, and hepatic cirrhosis. The purpose of this study is to develop animal model for hepatic fibrosis in pig with ethanol, and to search new anti-fibrogenic agent. Twelve male Landrace pigs were divided into 3 groups of 4 animals each. Group 1, 2 and 3 were fed with ceramic water only, ceramic water + liquid diet containing 20％ ethanol and normal tap water + containing 20％ ethanol for 12 weeks, respectively. At week 12, all pigs were immediately sacrificed for collection each tissue and blood. Serologically, serum ALT and AST levels were significantly reversed in group 2, comparing to group 3. They were normal range in pigs of group 1. Microscopically, macrovesicular lipid droplets and moderate necrosis were evident in the tap water + ethanol fed group 3. However, ceramic water intake group 1 showed normal. Moreover, in group 3, little fatty changes and mild necrosis were observed. Collagen fibers were detected in the spaces of surrounding periportal and interlobular areas in the group 3 of tap water + ethanol, but collagen synthesis and its thickness of fibrotic septa connecting portal tracts was markedly reduced in the group 2 of ceramic water + ethanol. In immunohistochemistry, myofibroblasts were detected in the ethanol and tap water treated group 3. No or a few myofibroblasts were observed in groups 1 and 2. CYP 2E1 was rarely detected in group 1 fed ceramic water. However, group 2 showed slightly activation of CYP 2E1 in the area of pericentral, while CYP 2E1 was significantly activated in group 3 fed tap and ethanol. Taken together above, alcohol fibrosis model in pig was established. Furthermore, ceramic water had an inhibitory and protecting ability for alcohol-induced hepatic damages.

The purpose of this study was to compare the apical sealing ability, overfilling and obturation of lateral canals using two gutta-percha techniques: Thermafil obturators and cold lateral condensation. Eighty numbered epoxide blocks with one major and five lateral canals were divided into four experimental groups and obturated according to experimental groups. Four experimental groups were as follows: Group 1 : Filling with Thermafil plastic obturators and sealer(ThermaSeal) Group 2 : Filling with Thermafil plastic obturators only, without sealer(ThermaSeal) Group 3 : Fillng using lateral condensation with sealer(AH-26) Group 4 : Fillng using lateral condensation without sealer(AH-26) All the blocks were stored in 100% relative humidor at room temperature for 7 days. Each block was placed in centrifuge tube filled with India ink, and then centrifuged for 20 minutes at 3,000 rpm. Apical leakage was measured from the apical foramen to the most coronal level of dye penetration in millimeter under a stereoscope. The length of gutta-percha and sealer in each of the lateral canals was measured, too. The presence or absence of overfilling of gutta-percha and sealer was recorded. The data was analyzed by one-way ANOVA. The obtained results were as follows: l. Apical dye leakage was almost: not occurred in Group Willed with Thermafil and sealer) and Group 3(filled using lateral condensation with sealer), and there was no significant difference in linear leakage between two groups(p>0.01). 2. In both Thermafil and lateral condensation groups, linear leakage of Group I, 3(filled with sealer) was less than that of Group 2, 4(filled without sealer), and there was no significant difference in linear leakage between Group 1, 2, 3(p> 0.01). 3. Overfilling during obturation of Group 1, 2(filled with Thermafil) was more than Group 3, 4(filled using lateral condensation), and there was no significant difference between groups(p> 0.05). 4. Groups filled with Thermafil had significantly more gutta-percha than groups filled using lateral condensation in all lateral canals(p <0.01), the total length of gutta-percha and sealer found in all lateral canals were similar in Group 1 and Group 3.

This study was performed to observe the histopathological response to the bonding resin directly applied on the remaining pulp tissues. 40 teeth from 3 adult dogs were pulpotomized with a sterile round bur and sharp excarvater. In the control group, $Ca(OH)_2$ powder was applied on the pulp tissue and the cavities were sealed with IRM cement. In the experimental group 1, Superbond C&B was applied on the remaining pulp and the cavities conditioned with 10-3 solution were filled with the mixture of the MMA liquid, PMMA powder and Catalyst. Multi-purpose adhesive was used on the remaining pulp tissue in the experimental group 2 and Z-100 was filled in the cavities. In the experimental group 3, Clearfil photobond applied and directly photo-cured on the pulp tissue, then the cavities were treated with CA agent (10% citric acid and 20% $CaCl_2$ aqueous solution) for 20 seconds, washed and applied with Clearfil photobond then filled with Protect liner. The experimental animals were sacrified at the 1st, 2nd, and 4th week. The specimens were routinely processed and stained with H-E for light microscopic observation. The results were as followed : 1. In the experimental group 1, the number and characteristics of the dentin bridge formation case was similar to those in the control group and less cases were observed in the experimental group 2 and 3 than experimental group 3. The inflammatory response in experimental group 1 was less than that in the control group at 1st week but there had been little difference at between 2nd and 4th week. 2. The number of the dentin bridge in experimental group 2 was less than that in control group and experimental group 1. The inflammatory response of the experimental group 1 was similar to that of experimental group 1 but less than that of the control group. A number of bleeding and vascular congestion were observed. The least inflammatory response was seen in the experimental group 2 among all groups. 3. In the experimental group 3, one case of the dentin bridge formation was observed and that was the same as that in the experimental group 2 but smaller than that of the control and experimental group 1. The inflammatory response of the experimental group 3 was least at the 1st week and most at the 4th week in the all group.

The aim of this study is to investigate the wound healing effects of the Opuntia ficus-indica. Four full-thickness skin wounds(2.5 cm × 2.5 cm) were made in different areas on the back in each of five dogs. Two wounds were used for wound size measurement and two for skin biopsy. The ten full-thickness wounds were treated with the extract of Opuntia ficus-indica, and the ten full-thickness wounds were treated with normal saline. The wound areas were measured every other day for three weeks after wounding. Statistical analysis was performed with the paired t-test. The wound healing rates were 32.9±4.0%, 28.2±7.1%, 42.2±4.1%, 55.0±4.3%, 76.6±2.8%, 86.8±2.3%, 94.0±1.l%, 97.3±0.8%, 99.3±0.3%, 99.8±0.2%, 100.0±0.0% in the experimental group, and 18.0± 8.2%, 13.S± 11.6%, 15.2±6.1 %, 36.9±8.8%, 62.4±4.1%, 80.0±2.3%, 86.0±1.4%, 94.0±0.9%, 96.9±0.8%, 97.8±0.3%, 99.7±0.1% in the control group on the 1/sup st/, 3/sup rd/, 5/sup th/, 7/sup th/, 9/sup th/, 11/sup th/, 13/sup th/, 15/sup th/, 17/sup th/, 19/sup th/, 21/sup st/ day. On the 17/sup th/ day, the wound closed above 99.9% in 1 dog of the experimental group. On the 19/sup th/ day, the wound closed above 99.9% in 3 dogs of the experimental group. On the 21/sup st/ day, the wound closed above 99.9% in 5 dogs of the experimental group, and 1 dog of the control group. The wound healing period was shortened by 2 to 4 days in the experimental group as compared with the control group. The tensile strength was 4,508±513 g/㎠ in the experimental group and 2,772±400 g/㎠ in the control group on the 21/sup st/ day after wounding. The tensile strength was significantly higher in the experimental group than in the control group(p< 0.05). Inflammation rapidly spread and disappeared in the experimental group but not in the control group. Fibroblast and vascularization were found on the 5/sup th/ day in both group and increased only in the experimental group on the 9/sup th/ day. The firs finding of epithelialization was on the 13/sup th/ day in the experimental group and the 21/sup st/ day in the control group. A significantly higher wound healing rate(p< 0.05), tensile strength(p< 0.05) and better histopathological findings were observed in the experimental group than in the control group throughout the experimental period. These results suggest that topical application of Opuntia ficus-indica extract can promote wound healing in dogs.
