To facilitate the widespread application of somatic cell cloning, improvements in blastocyst production efficiency and subsequent fetal viability are required. Area where technical improvements are needed include donor cell treatments, starvation and passage numbers. This study was carried out to investigate the effect of serum-starvation and passage on the development of ear skin fibroblast cells cloned embryos. A skin biopsy was obtained from the ear of a 2-year-old Korean Hanwoo female. The cells were cultured in 10% FBS＋DMEM up to 2-3 months(up to 10 passages) and then used. In Experiment 1, the Korean bovine Ear Skin Fibroblast cells (KbESF) were either serum starved (culture in 0.05% FBS＋DMEM) or serum fed (10% FBS＋DMEM) for 4-7 days Prior to NT In Experiment 2, the KbESF cells used for nuclear transfer in these experiments were from passages 2 to 10. The development of 208 nuclear transfer (NT) embryos reconstructed from either serum starved or serum fed ear skin fibroblast was assessed. NT embryos reconstructed from serum starved and serum fed cells showed the same developmental rate (cleavage 80.16 vs. 85.37%; blastocyst 20.63 vs. 19,51%). The development of 590 nuclear transfer (NT) embryos reconstructed from passage 2 to 10 was assessed. We observed the same developmental rates for embryos derived from later Passages as compared with those embryos from early passages(blastocyst from 16.69 to 27.91%, average 20.17%). There was no significant difference between serum-fed and serum-starved donor cells. We observed no difference in developmental rates for embryos derived from 2 to 10 passages. These data show that prolonged culture and serum starvation does not affects the cloning competence of adult somatic cells.

Objective : Yukmijihwang-tang is one of the important medicines for blood- deficiency and yin-deficiency. Atopic dermatitis usually shows dampness-heat pattern in its acute stage and blood-deficiency or yin-deficiency pattern in its chronic stage. Therefore, I hypothesized that Yukmijihwang-tang is effective on atopic dermatitis and investigated the effects of Yukmijihwang-tang on NC/Nga mice's atopic dermatitis induced by DNCB. Methods : The NC/Nga mice with atopic dermatitis were divided into four groups: three experimental groups and one control group. The experimental groups were respectively put on 2.5g(YM-2.5), 5g(YM-5) and 10g(YM-10) of Yukmijihwang-tang extract per their weight once a day for 10 days while the control group was fed normal saline. After 10 days, I measured TEWL(transepidermal water loss), observed scratching behaviors, conducted a skin biopsy and checked levels of Total IgE, IL-4 and $IFN-\gamma$ on NC/Nga mice. Results : 1. Yukmijihwang-tang significantly suppressed skin dryness. In particular, YM-5 and YM-10 had better skin hydration than YM-2.5. 2. Yukmijihwang-tang significantly suppressed pruritus while there was no significant difference among the experimental groups. 3. Yukmijihwang-tang retained skin structure(epidermis, dermis and subcutaneous fat). 4. Yukmijihwang-tang reduced Total IgE level while there was no significant difference between the control group and the experimental groups. 5. Yukmijihwang-tang did not reduce IL-4(Th2 cytokine) level. 6. Yukmijihwang-tang significantly reduced $IFN-\gamma$(Th1 cytokine) level. In particular, YM-2.5 and YM-5 had lower $IFN-\gamma$ level than YM-10. Conclusion : The results suggest that Yukmijihwang-tang suppresses skin dryness and pruritus, retains skin structure and is effective on chronic atopic dermatitis which is associated with Th1 cytokines in the immune response.

A 60-year-old male presented with a three-month history of redness and swelling on his left little finger. His medical history was not informative. Wound culture revealed methicillin-resistant Staphylococcus aureus. After vancomycin administration, the skin lesions became worse and whole body bullae and desquamation occurred. This was initially suspected to be a drug eruption; thus, we switched antibiotics from vancomycin to teicoplanin. However, biopsy revealed Staphylococcal scalded skin syndrome (SSSS). After several days, generalized skin symptoms improved. The patient recovered and is in good physical health without recurrence six months later. We describe a localized form of SSSS, which is very rare in healthy adults. Consequently, there is a high risk of misdiagnosis. Thus, we report a rare case of SSSS in a healthy adult and the importance of early histological examination for accurate diagnosis.

An 8-year-old, castrated male Shih-tzu was referred due to relapsing pododermatitis and generalized pruritus. On physical examination, right forepaw showed swelling and serosanguinous exudates from sinus tract on dorsal paw. There were no remarkable findings on complete blood count (CBC), serum chemistry, and radiologic examination. On cytological examination of exudates from sinus tract, phagocyted bacteria and numerous degenerative neutrophils were noted. Results of deep skin scraping and plucking hair examination were unremarkable. Skin biopsy was performed and ruled out other skin diseases. Histopathology showed epidermal hyperplasia and diffuse mononuclear cell inflammation in dermal layer. Moreover, pyogranulomatous inflammation was demonstrated in subcutaneous layer. This case was clinically diagnosed as pododermatitis secondary to atopic dermatitis (AD). Clinical signs of pododermatitis were gradually improved following topical application of tacrolimus 0.1% ointment. This case report describes that tacrolimus ointment can be applicable for the treatment of refractory pododermatitis.

Purpose: The purpose of this study is to document the surgical methods used in infants with aplasia cutis congenita treated with allogenic dermal matrix and cultured epithelial autografts. Methods: The large defects in both lower legs were replaced with allogenic dermal matrix to avoid the postoperative hypertrophic scar contracture and a full-thickness skin biopsy was taken from right groin area simultaneously. We sent the specimen to a commercial laboratory for culture and obtained cultured epithelial autografts($Holoderm^{(R)}$) after 2 weeks, placed it over the allogenic dermal matrix. Results: The skin-defected area were nearly epithelialized after 2 weeks and there were no significant problem on during 6 months follow-up. Conclusion: The surgical method using allogenic dermal matrix and cultured epithelial autograft provided an excellent coverage of large skin defects of infant with aplasia cutis congenita.

An 11-year-old, female Miniature Schnauzer dog was presented with recurrent skin ulcer of the second metatarsal region in the right hindlimb following metatarsal resection. Physical examination revealed an ulcerated and bleeding lesion of the second metatarsal region in the right hindlimb. Impression smears of the ulcerative lesion confirmed numerous degenerated neutrophils and mixed bacterial infection. Initially, the dog was treated with antibiotics and povidone-iodine flushing for the control of deep pyoderma. Because the skin lesion had been deteriorated over time despite of topical and systemic treatments, skin biopsy was performed. Histopathologic examination indicated squamous cell carcinoma based on the features of multiple nests of squamous neoplastic cells and mitotic figures. Although amputation of the right hindlimb was performed, the dog was expired five months later because of tumor metastasis to the lung and the popliteal lymph node. This is the first case report describes malignant digital squamous cell carcinoma in Korea.

Herpetic mastitis is extremely rare, and its imaging findings remain unclear. We report a case of herpes simplex mastitis in an adolescent woman and describe the clinical and ultrasound features. The patient showed unilateral nipple and areolar skin thickening and axillary lymphadenopathy on B-mode ultrasonography. Doppler ultrasonography revealed multiple linear and branching blood flows in the areolar area. The lesion was verified as herpes simplex mastitis via a skin biopsy. This report shows that the radiologic features of herpes simplex mastitis may be similar to those of Paget's disease because of localized nipple and areolar skin thickening and increased vascularity.

Medical records of 139 tumors from 114 dogs that underwent surgery from May 2010 through March 2015 were retrospectively reviewed. Among 114 dogs, females (64.9%) were significantly more common than males (35.1%) (p<0.05). Dogs aged 6 to 10 years were more presented than non-tumor patients, however, there was no significant difference. The mean age (±SD) was 10.3±3.0 years. Although we found no significant difference of breed predisposition, the most common breed was Maltese (19.3%), followed by Shih-Tzu (14.0%), and Yorkshire terrier (13.2%). Proportional morbidity ratios (PMRs) of mammary gland, oral cavity, and skin tumors were high in Poodles, Yorkshire terriers, and Golden retrievers, respectively. Mammary gland (36.0%) was the most common site, followed by skin and soft tissues (12.2%), oral cavity (10.8%), and digestive organs (8.6%), but there was no significant difference. The objectives of surgery were curative surgery (86.2%), biopsy (4.9%), and palliative surgery (6.5%). In this study, 123 of 139 tumors had histopathological diagnoses. Adenocarcinoma was the most common type (n=24), followed by adenoma (n=17), soft tissue sarcoma (n=13), benign mixed tumor (n=5), and others (n=64). Recurrence or suspected metastasis was identified in 26 dogs. Median survival times of malignant mammary gland tumors, skin and subcutaneous tumors, and splenic tumors were 1,563.0±1,201.7, 469, and 128 days, respectively.

Pleomorphic adenoma is a benign tumor that can occur in the salivary glands, most commonly in the parotid gland. While it primarily occurs in the major salivary glands, it can sometimes be found in the minor salivary glands. Within the minor salivary glands, it most often originates in the hard palate and soft palate, and less frequently in the upper lips. Due to its location in the minor salivary glands, most pleomorphic adenoma involve and protrude on the mucosa. A 61-year-old man presented with 1.5 cm exophytic mass on the skin of his upper lip. This mass was exophytic on the skin and did not involve or protrude into the inner lip mucosa. The mass was entirely excised, and a subsequent permanent biopsy diagnosed it as a pleomorphic adenoma. In such situations, it can be challenging to suspect pleomorphic adenoma during a physical examination, leading to potential diagnostic confusion. It might also be mistaken for an inclusion cyst or another type of mass, making it tempting to treat without verifying the pathological results.
