  • A 4-year-old female beagle with progressive exophthalmos and which had a neoplastic mass with diameter of 1.4 cm in the left lower ocular adnexa. Histologically, the mass was composed of hyper-plastic lobules and tubular structures separated by fibrous septum. The well differentiated sebaceous gland forming various sized lobules, and infiltration of mast cells and mononuclear inflammatory cells were observed. Apical decapitation secretion of these tubular structures with basophilic materials in their lumen showed mild sebaceous gland metaplasia. Immunohistochemical studying, cell groups were positive in ${\alpha}-SMA$ and vimentin. The primary tumor was diagnosed as adenocarcinoma originated from moll gland and meibomian gland of the eyelid, and the infiltrating intraocular neoplasm was diagnosed as a malignant mixed tumor.

  • This study was performed to develop new cosmeceutical agents with sebosuppressive activity from native plant extracts in Korea. Inhibitory efforts of the extracts on $5{\alpha}-reductase$ (5-AR) were evaluated by enzyme kinetics analysis using UV-spectrophotometric method. Two kinds of enzyme suspensions as 5-AR sources were prepared from rat liver tissue and cultured hSG cells. The sebosuppressive effects were determined by measuring the total lipid quantity produced in cultured hSG cells after incubation with the extracts. As a result, Pinus thunbergii extracts showed the most potent 5-AR inhibitory effects. Its $K_i$ values were 0.0002% and 0.0014% for rat liver 5-AR and human sebaceous gland 5-AR, respectively. Addition of Pinus thunberii extract to hSG cells showed 48% reduction in total lipid production at 0.005% concentration. In conclusion, Pinus thunbergii extracts can be used as a cosmeceutical agent to regulate sebum production and to alleviate the sebum-involved skin diseases, such as acne and seborrheic dermatitis.

  • Sex and its tropic hormones influence the lacrimal system, corneal anatomy and disease, aqueous humor dynamics and glaucoma, crystalline lens and cataract, and retinal disease. Dry eye occurs especially frequently during pregnancy, oral contraceptive use, and after menopause, during which androgen levels decrease. Androgen control development, differentiation, and lipid production of sebaceous glands throughout the body, and androgen deficiency also leads to meibomian gland dysfunction and evaporative dry eye. On the other hand, estrogen causes a reduction in size, activity, and lipid production of sebaceous glands. Sex and its tropic hormones also influence the corneal anatomy and disease, and corneal thickening occurred on the second day of the menstrual cycle and around the time of ovulation and appeared to be related to estrogen levels. Fuchs' dystrophy is more commonly seen in postmenopausal women than men and may be linked to hormonal changes that occur with aging. In addition, overexpression of estrogen and progesterone receptors in the conjunctiva of vernal keratoconjunctivitis patients. Serum progesterone levels also may be associated with intraocular pressure especially in pregnant women, and for the women. For women with cataracts, hormone levels were typical of menopause, and there was a significant negative correlation between estradiol and follicular stimulating hormone levels. In addition, serum testosterone levels are associated with the development of diabetic retinopathy. Although the role of sex hormones on the eye is largely unknown, and the results should be interpreted with caution until replicated, the functions of sex hormones in ocular disease remains to be investigated, because they may be involved in structure and function of the ocular components, which are important in the pathogenesis of ocular disease.

  • During radiation therapy with electron beam to eyelid, we must keep the minimal dose on eyeball as possible. especially in the treatment of Sebaceous gland carcinoma, Squamouse cell ca., and basal cell ca. of eyelid and low grade MALToma etc. But if radiation field covered the upper & lower eyelid, it makes a cataract on lens of treated eye, in late complications. Now we reports the advantages of Tungsten eyeball shielding block compare to previously used lead block. with BOLX-I material, we made a eyeball model and measured the absorbed dose of 6MeV & 9MeV electron hem at 6 point of eyeball model with TLD chip. And compare the absorbed dose to previously lead block and other types of Tungsten eyeball shielding block.

  • In order to elucidate the pathogenesis of cleft lip and palate, first of all, it is necessary to understand the developmental mechanisms of growth factors and extracellular matrix proteins in the tissues of cleft lip and palate. We have performed immunohistochemical studies on human cleft lip and palate tissues to elucidate the pathogenetic implications of cleft lip and palate. 16 specimens from postnatal human cleft lip and palate subjects and 17 specimens from autopsy of prenatal human cleft lip and palate were fixed in 10% buffered formalin, embedded in paraffin. The sections were routinely stained by hematoxylin and eosin, also stained by PAS, and followed by immunohistochemical stainings using the antiseras of growth factors and extracellular matrix proteins such as PCNA, S-100, c-erb-B2, MMP-3, MMP-10, HSP-70, transglutaninase-C, E-cadherin, VEGF, vWF. Both the prenatal and postnatal specimens of cleft lip and palate showed dysplastic proliferation of the basal cell layer, increased infiltration of melanocytes into mucosal epithelium, sebaceous gland hyperplasia ingrowing into the muscular tissue of lip and palate, and fatty infiltration into the submucosal deep connective tissue. The strong reactions of MMP-3 and HSP-70 were detected in the tissues of cleft lip and palate, especially increased in degenerating muscle bundles, while the immunostainings of PCNA and c-erb-B2 were weakly positive in the tissues of cleft lip and palate. These data suggest that the retrogressive tissue degeneration around the cleft areas persistently exist during the prenatal and postnatal period after cleft formation, and the sebaceous gland hyperplasia and fatty infiltration with the intense expression of MMP-3 and HSP-70 is closely related to the muscular degeneration around the cleft area.

  • Sebum is secreted due to the effect of androgen, which start to be secreted at puberty. Androgens have profound effects on the physiology of the sebaceous gland, Using the human sebocyte cell line SZ95, we investigated the inhibitory effect of Chelidonii Harba (CH) on the subum production. Our results showed that numerous cytoplasmic lipid droplets were examined by Oil red staining and lipid droplets were increased markedly by testosterone. Cell viability was dose-dependently decreased by CH as compared with untreated cells, while total lipid content and cholesterol slightly were increased by CH. Testosterone significantly stimulated the synthesis of total lipid and the synthesis of specific sebaceous lipids such as cholesterol and triglyceride. Combined treatment with CH and testosterone resulted in a lower lipid synthesis than with testosterone alone. Especially cholesteol content was reduced by combined treatment with CH and testosterone. These results indicate that CH inhibits the testosterone-induced lipid synthesis in SZ95 cells and acts antagonistically to androgen at the cellular level.

  • Skin tumors and mammary gland tumors have been shown to be the most common neoplasia in most of the strains of dogs. The risk for tumor development increases significantly with age and the prevalence and distribution are various according to individual tumors. The aim of this study is to classify histopathologically the skin and mammary gland tumors for recent two years, 2005 and 2006. A total of 128 skin and 240 mammary gland samples of dogs were selected that were submitted to National Veterinary Research and Quarantine Service and Kangwon National University from January 1, 2005 to December 31, 2006. The excised tissue were fixed in 10 percent neutral buffered formalin and processed routinely to paraffin wax. Sections were cut at $3{\mu}m$, stained with haematoxylin and eosin. The slides were examined based on the morphological criteria of M. H. Goldschmidt and W. Misdorp under a light microscope. The age of the dogs ranged from 1 to 19 years with a median of 8.7 years. The mean age of the skin and mammary gland tumors was 7.4 and 9.3 years. 47 (12.8%) were males and 259 (70.4%) were female with a male to female ratio of 0.18. Yorkshire terrier and maltese were more susceptible breeds, accounting for 44.3% of skin and mammary gland tumors. In skin tumors, epithelial, adnexal, and mesenchymal origin tumors were 18 (14.1%), 53 (41.4%), and 57 cases (44.5%), repectively. Among the epithelial, adenexal, and mesenchymal origin tumors, basal cell tumor (8.6%), sebaceous adenoma (15.6%), and histiocytoma (25.0%) were predominant in the incidence rate, respectively. In case of mammary gland tumors, 201 (83.8%) were benign and 39 (16.3%) were malignant with a benign to malignant ratio of 5.15. The most frequent mammary gland tumor was benign mixed tumor (35.0%) followed by mammary adenoma-complex type (31.7%).

  • Acne is a chronic, inflammatory disorder that mainly affects teenagers and young adults. The disease has many causes, blocking hair follicle or sebaceous gland. Acne is not life threatening, but quality of a patient is compromised. Therefore, the patient needs an active treatment. With this in mind, I witnessed some noticeable improvement among the patients by prescribing Myunposan(面疱散). Here are the findings of my experience. 1. Out of acne patients who visited Oriental Medicine Hospital of Kyung-Won University(暻園大學校서울韓方病院) during September 2000 - December 2000, 8 patients whose prognosis is dramatic were subjects. 2. Myunposan(面疱散) deems effective in removing wind(祛風), unnecessary metabolite(祛痰), heat(淸熱), and draining pus(排膿), and preventing evil effects(解毒). 3. In the case of those 8 success stories as a result of taking Myunposan(面疱散), in the order of redness, pain, iching, and fever, symptoms were quick to disappear, and papula, pustula, etc got better albeit slower. 4. Depending on general symptoms, oriental medicine and acupuncture treatment on top of taking Myunposan(面疱散), symptoms were even quicker to go away and improved.
