A 13 years old terrior dog with vaginal tumor was referred to the animal hospital of Chungnam National University. Resection of vaginal tumor through perineal area was performed. The results obtained were as follows. 1. Histologically, tumor was classified with fibroma. 2. The skin and musculature of the perineal area was incised to the dorsal area of the vaginal wall except I em of width over the dorsal commissure of the vulvar cleft. Through the opening of the wound, pedunculated tumors were amputated and diffused tumors were removed by submucosal resection. After the surgical operation, the original shape of the external area of vulva was not changed. 3. After the resection recurrent sign was not observed up to nowadays for about 6 months.

Numerous novel ingredients have been introduced for the higher functionality of whitening cosmetics. Through the preliminary research, we have found Trichosanthes kirilowii root, Prunella vulgaris leaf and Clematis chinensis root have high whitening efficacy. But they are insoluble. Moreover the discoloration of and decrease in content take place when they are exposed to light, heat or oxygen. From Trichosanthes kirilowii root, Prunella vulgaris leaf and Clematis chinensis root, efficacious ingredients were ethanol-extracted by heating to 75∼85$^{\circ}C$ for 6∼8 h. These extracts have the inhibitory activity of tyrosinase and B16 melanin formation, thus enhancing whitening effect. We made liposomes using propylene glycol (PG)/hydrogenated lecithin/middle chain triglycerides (MCT)/glycerin/water and microfuidizer to stabilize extracts. The stability against heat and light was enhanced by 3∼5 times compared with untreated extracts. Particle size analyzer, freeze fracture transmission electron microscopy (FF-TEM), chromameter and HPLC are used for the analysis.

Purpose: The purpose of this study was to examine the parenting of mothers with infants and preschoolers in an effort to determine types of parenting. Methods: The 32 participating mothers were interviewed and from the content of the interviews, their parenting was analyzed. Statements were categorized and analyzed according to the selected procedure. Results: The parenting of mothers was classified into positive reinforcement and negative reinforcement, including 55 significant statements and 14 categories. Positive reinforcement was categorized as frequent skin contact, giving pleasure, spending a lot of time with children, improving children's self-esteem, being sensitive to children's needs, realistic discipline, developing independence, listening to children, and understanding and respecting children's feelings. Negative reinforcement was categorized as overprotection, inconsistent attitude, negligence, negative educational behavior, and emphasis on obedience. Conclusion: These results suggest that systematic education should be provided for mothers to increase their ability to provide good parenting. It is expected that the findings of this study would be useful in the development of efficient educational programs.

Coenzyme Q10 (CoQ10) is a natural lipid cofactor with antioxidant and anti-aging properties as cosmetic and food ingredients, involved in cellular energy metabolism. Here, nano-emulsions with CoQ10 were fabricated with lecithin, ethanol, oil, and sorbitan monostearate (Arlacel 60), as major components. Phase inversion emulsion method with ultrasonicator was utilized in producing CoQ10 solution, and stabilization effects from lecithin and ethanol and other diverse perturbation factors were evaluated over time. Physical properties of the emulsion were characterized such as its size, surface charges by zeta-potential, and the overall structures. Optimal concentrations of CoQ10 and Arlacel 60 were 0.8% and 3%, respectively, for producing the smallest sizes of nanoemersions in a 100 nm diameter with best morphology. No notable changes in the size were observed over 7 days from Ostwald ripening, when the concentration of Arlacel 60 was higher than 2%. Even after 270 days at room temperature, the size of nanoemulsions maintained as 115 nm in diameter, revealing only a 10% increase with high degrees of long termed stability and substantiality. In addition, changes in the surface potential occurred possible due to the flocculation effect on the nanoparticles.

This work presents o novel method which extract facial region und features from motion picture automatically and controls the 3D facial expression in real time. To txtract facial region and facial feature points from each color frame of motion pictures a new nonparametric skin color model is proposed rather than using parametric skin color model. Conventionally used parametric skin color models, which presents facial distribution as gaussian-type, have lack of robustness for varying lighting conditions. Thus it needs additional work to extract exact facial region from face images. To resolve the limitation of current skin color model, we exploit the Hue-Tint chrominance components and represent the skin chrominance distribution as a linear function, which can reduce error for detecting facial region. Moreover, the minimal facial feature positions detected by the proposed skin model are adjusted by using edge information of the detected facial region along with the proportions of the face. To produce the realistic facial expression, we adopt Water's linear muscle model and apply the extended version of Water's muscles to variation of the facial features of the 3D face. The experiments show that the proposed approach efficiently detects facial feature points and naturally controls the facial expression of the 3D face model.

We studied the effects of smoking, which is one of indoor-environmental pollutants and related to various cancers, on glycoconjugates of rat sebaceous glands with the lectin histochemistry. To investigate the effects of smoking on glycoconjugates, male Sprague-Dawley rats were exposed to tabacco smoke for 10 minutes per day in an inhalation chamber for 1, 2, 3, and 5 days with active and passive exposure. For the structure of sebaceous glands we used PAS reaction, and for the glycoconjugates binding pattern 9 biotinylated lectins (DBA, SBA, PNA, BSL-1, WGA, RCA-1, UEA-1, Con A, and LCA) were used. Some remarkable changes, such as the decrease in the size of sebaceous glandular acini, the destruction of upper portion of sebaceous glands, vacuolation of central portion of sebocytes, and the immature sebaceous glandular acini were seen in the smoke-exposed rats. In the control rats, basal cells were stained with BSL-1, PNA and WGA, but the stronger reaction was founded in BSL-1 binding. Also, sebocytes were stained with PNA, WGA, Con A, BSL-1 and SBA, but stronger reactions were founded in PNA and Con A stainings. Specific changes in the lectin binding patterns were also observed in the smoke-exposed rats. In the basal cells of exposed rats, PNA binding increased, BSL-1 decreased but returned to control level, and WGA disappeared. Plus, immature glandular acini, which were not found in the control rats, were stained PNA, Con A and BSL-1, but the stronger reaction were founded in PNA and Con A binding. In conclusion, it was assumed that the tabacco smoke seriously effected on the structure and glycoconjugates metabolism of sebaceous glands.

This study was carried out to investigate the anti-wrinkle effects of peptides derived from collagens isolated from Asterias amurensis, which was collected in the East Sea. The molecular weights of the peptides were between 10-50 kDa, as determined through sephadek G-75 gel. The cytotoxicities against CCD-986sk cells and HEL-299 cells were measured using the MTT assay. The cytotoxicity of all the fractions(F1: Fraction No. 4-13, 116 kDa; F2: Fraction No. 25-30, 100 kDa; F3: Fraction No. 45-55, 58 kDa; F4: Fraction No. 59-63, 43 kDa; F5: Fraction No. 79-90, 24 kDa) was less than 25%, by the addition of 1.0 mg/mL. These peptides did not show any adverse effects on human skin cells. In the presence of F1 at 1.0 mg/mL, matrix metalloproteinase-1 (MMP-1) expression of UVA-induced human normal fibroblasts was reduced to 34.8%. Overall, the results seem to suggest that peptides of approximately 20 kDa have superior anti-wrinkle effects.

Toxic gases and soot deposition as a consequence of smoke inhalation can cause direct injury to the upper and lower airways and even to the lung parenchyma. A delay in proper and prompt therapy can be detrimental to critically ill burn patients with an inhalation injury. Therefore, serial chest radiography is an important diagnostic tool for pulmonary complications during treatment. The radiographic findings of the chest include normal, consolidation, interstitial and alveolar infiltrates, peribronchial thickening, atelectasis, cardiogenic and non-cardiogenic pulmonary edema, and a pneumothorax as acute complications of smoke inhalation. In addition, bronchiectasis, bronchiolitis obliterans and pulmonary fibrosis can occur as late complications. We encountered a case of 44-year-old male who presented with acute lung injury after an inhalation injury. He required endotracheal intubation and mechanical ventilation due to respiratory failure. He was managed successfully with conservative treatment. Later, a cavitary lesion of the left upper lobe was observed on the chest radiography and computed tomography, which was complicated by massive hemoptysis during the follow-up. However, the cavitary lesion disappeared spontaneously without any clinical consequences.
