Purpose: Plastic surgeon can easily misdiagnose the mass on the postoperative scar as hypertrophic scar. We present a case of endometrioma at abdominal scar after cesarean section. Methods: A 36 year-old female visited with a protruding, rubbery hard mass on her abdominal scar. The mass grew slowly after cesarean section performed 7 years ago. She has felt intermittent pain, not with menstrual cycle, for 2 months. The ultrasonography showed a solid irregular, ill defined mass with heterogenous echogenicity. The MRI finding is suggestive of malignant soft tissue tumor with deep fascial invasion. Incisional biopsy showed acanthosis, melanophage, lymphoplasmacytic infiltration. So we excised mass elliptically, we could see chocolatelike discharge from the mass, adhering to external oblique muscle fascia. The mass confirmed histologically as an endometrioma. Results: The mass was completely removed and did not recurr. The patient does not complain more about pain or any discomfort. Conclusion: Plastic surgeons should be aware of the possibility of endometrioma when the patient present with mass on her abdominal scar after surgery of the pelvis and abdomen.

Objective: The objective of the study was to evaluate the effect of Sharbat Afsantin in Polycystic Ovarian Disease. Methods: An open observational study was carried out in the Department of Ilmul Qabalat wa Amraze Niswan. Diagnosed cases(n=30) of PCOD were included in the study. Patients with thyroid dysfunction, systemic diseases, on hormonal treatment in last three months, pregnancy and lactation were excluded. Research drug (Sharbat Afsantin) was administered orally in a dose of 25ml twice daily for 15 days/cycle for three consecutive cycles. Outcome measures were, changes in subjective parameters (duration of cycle, duration and amount of flow and weight reduction) and objective parameters {pictorial blood loss assessment chart (PBAC) score, basal metabolic index (BMI), modified Ferriman Gallwey (mFG) score, acanthosis nigricans scale and pelvic ultrasonography}. Data were analyzed using paired Student 't' test. Results: Changes in duration of cycle, duration and amount of flow were achieved in 83.3%, 50% and 40% patients respectively and weight reduction in 30% patients. Changes in PBAC score and BMI were achieved in 50% and 30% patients respectively and 30% patients showed normal findings on pelvic ultrasonography. Conclusion: Sharbat Afsantin can be used as an alternate remedy in PCOD patients, as it has significant effect to regularize menstruation by reduction in BMI and probably by improving insulin resistance in PCOD. No adverse effect of Sharbat Afsantin was noted during the trial.

Recent studies have revealed that Nitric oxide(NO) was one of the demonstration for the physiological regulator, endothelial derived relaxing factor(EDRF) and that NO was produced by ultraviolet irradiation in human. Thus, the present author have carried out a experimental study on the change of hematological, histological value of ultraviolet irradiation in sprague-dawley rats. The subjects were divided into four groups of ten rats each selected at random. There were 4 groups: 1. no irradiation control; 2. ultraviolet $75mJ/cm^2$ irradiation group; 3. ultraviolet $150mJ/cm^2$ irradiation group; 4. ultraviolet $225mJ/cm^2$ group. After a irradiation, hematological and histological tests were performed to observe erythrocyte, hemoglobin, hematocrit, MCH, MCHC, MCV, $O_2$ saturation, pH, $PO_2,\;PCO_2$ value and to observe histological changes. In hematological tests, erythrocyte, hemoglobin, hematocrit significantly increased in $75mJ/cm^2$ than control group and more $150mJ/cm^2$ ultraviolet irradiation group respectively. Also In blood gas tests, $PO_2$ significantly increased in $75mJ/cm^2$ and more $150mJ/cm^2$ group than control group. Whereas $PCO_2$ significantly decreased in $75mJ/cm^2$ and more $150mJ/cm^2$ group than control group (Duncan-Tukey test, P<0.05). In histological tests, control and $75mJ/cm^2$ group unchanged, but more $150mJ/cm^2$ group changed that it was cytolysis, cytotoxic effect, acanthosis, proliferation of keratinocyte, appearance of amorphous cell and pyknotic nucleus, production of sunburn cell. In conclusion, the present author results support the importance of the relation between NO effect and hematological, histological value by ultraviolet B irradiation.

Recently, the consumption of soy products has been associated with low rates of hormone-dependent and hormone-independent cancers. Asians, who consume $20{\sim}50times$ more soy per capita than Americans, have lower incidence and death rates from breast and prostate cancer. Because soy contains the isoflavones genistein and daidzein (present as their glycosidic conjugates) at mg/g concentrations, it has been suggested that isoflavones might be acting as natural chemopreventive agents. During the 1980s several groups of investigators carried out experiments to test the effectiveness of soy in the diet in animal models of cancer. These studies reported a protective effect of soy; none showed that soy increased cancer risk. Genistein was shown to inhibit the growth of a wide variety of tumor cell types in culture. The purpose of this study was to evaluate the effects of genistein on the carcinogenesis induced by topical application of 0.5% 9, 10-dimethyl 1,2-benzanthracene (DMBA) on the hamster buccal pouch. 48 syrian hamsters were employed in this study, divided into experimental group and control. 24 animals (DMBA topical application group) had the right buccal pouch painted 3times weekly with 0.5% DMBA in mineral oil, 24 animals (genistein group) were supplied with 0.1mg genistein with DMBA topical application. 3 animals in the experimental group and control were sacrificed at serially each other week after experiments. Their buccal pouches were removed and routinely processed for microscopic examination. The results were as follows: 1. In DMBA topical application and genistein group, they showed carcinogenesis as time goes by experimental stage. 2. Genistein group was retarded in carcinogenesis related to the acanthosis, hyperkeratosis, epithelial dysplasia. 3. p53 immunohistochemical study showed that the p53 protein of genistein group was less expressed than that of the control group. Thus, it seems that genistein has chemopreventive effect on the carcinogenesis in the oral cavity, but further study is required to elucidate the anticancer mechanism of genistein.

A 6-year-old, neutered female, Cocker spaniel presented with severe abdominal erythema and crusts. These conditions developed 1 month ago. This patient had a history of using humectant spray for several months. Irritant contact dermatitis was diagnosed by history, clinical signs, laboratory and histopathologic examinations (H-E stain). Complete blood count and serum chemistry showed no remarkable findings. Histopathologic examination of skin samples revealed parakeratosis accompanied by acanthosis of the dermis and mild perivascular inflammations of the superficial dermis. Clinical signs were improved after avoidance of suspected offending substance.

Oral verruciform xanthoma (OVX) is an uncommon lesion that appears on the oral mucosa. The aim of this paper was to discuss the probable etiopathogenesis of OVX in the hard palate, reinforcing the importance of including this lesion in the differential diagnosis of verrucous lesions. A 43-year-old male smoker presented with a painless lesion with a verrucous surface and erythematous spots on the hard palate. Excisional biopsy revealed oral mucosa consisting of hyperkeratosis, acanthosis, and elongated rete pegs. Subjacent connective tissue showed numerous foam cells with clear cytoplasm and pyknotic nucleus, negative on periodic acid-Schiff staining. Immunohistochemical analysis revealed foam cells positive for anti-CD68 antibody, while anti-KI-67 antibody was restricted to the basal layer of the oral epithelium. A final diagnosis of OVX was established. The patient showed no signs of recurrence after seven months of follow-up. Physical trauma and smoking habits can be directly related to the etiology of verruciform xanthoma because the lesion is chronic and inflammatory with slow growth, and sites if high trauma are more often affected by such a lesion. The hard palate is the second most commonly affected site, and local trauma caused by smoking can be a cause of this type of lesion.

Recently, the number of stray dogs is proportionate to the increase of the number of the companion dogs. Sarcoptic scabiei var canis, causing scabies, is one of the most important canine zoonotic arthropods in Korea and around the world. Thus, we have tried to know the prevalence of canine scabies in the stray dogs in Korea. A total of 565 stray dogs were collected from the rescue centers all over the country from Jan. 2006 to Dec. 2006. They were grouped with euthanasia or natural death and examined for the gender and age estimated by dental formula. To identify the lesions, the whole body was grossly examined and tested pathologically. Thirty two (5.66%) of 565 dogs were diagnosed as canine scabies. Dogs from urban areas had fewer scabies (0.62%) than those of rural areas (12.5%). Prevalence of scabies in male and female dogs was no difference as 5.96% and 5.25%. Euthanasia group showed higher prevalence (6.48%) than natural death group (2.44%) in scabies. Old dogs over five years showed lower infestration (1.82%) in scabies. In histopathological findings, there were mites in the burrows formed in the subcorneal space. Acanthosis, hyperkeratosis with crust, and vascular dilatation were main findings. One hundred thirteen (20%) of 565 stray dogs were diagnosed to have skin disease. Among them, canine scabies is the most prominent ectoparasite as 5.66 %. With previous reports on human infection in Korea, canine scabies must be regarded as the important zoonotic canine skin disease. Accordingly, for the human and canine hygiene it is imperative that stray dogs with skin problems are segregated and tested for the parasites to treat properly as soon as arriving at rescue shelter.

Guinea pigs were cutaneously inoculated with Trichophyton verrucosum var album, that is a common causative fungus of dermatophytosis in cattle. The developmental process of lesions, clinical and histopathological changes and reisolations of the fungi were studied to evaluate the pathogenicity of Trichophyton verrucosum var album in guinea pigs. Results obtained through the experiments were summarized as follows : 1. The incidence of infection of the clipping group was 13(86%) of 15 animals, and that of the plucking group was 14(93%) of 15 animals. In both of the clipping and plucking groups, visible cutaneoas lesions were developed between 4 and 7 days post inoculation(p.i.). The spreading and the climax stages persisted for 4 to 11 and 6 to 12 days, respectively. 2. In macroscopic observations, formation of various degree of erythemas and scales over the inoculated skin sites were observed in the spreading stage. In the climax stage, exudative changes and dark red crusts were formed as typical circular lesions. In the healing stage, the lesions revealed shedding of crust, alopecia and hair regrowth. 3. In histopathological observations, infiltration of inflammatory cells, hyperplasia, microabscesses and keratinous-hyaloid materials of epidermis were observed in the spreading stage. Hyphal invasion was primarily observed at the level of epidermis and pilosebaceous ducts. In the climax stage, the infected epidermis was thick with severe hyperplasia, hyperkeratosis and acanthosis. The microabscesses with fungal hyphae, folliculitis and hyperplasia of external root sheath were observed in the dermis. The fungal hyphae were observed only in the tissues of hair follicles, that were internal root sheath, cuticle, the keratinized portions of cortex and medulla 4. In reisolation of the inoculated fungus, all trials for ten animals showed positive cultures until 25 days p.i.. Afterward, the reisolation rates were gradually decreased, showing all negative after 40 days p.i..

Genistein that is a component of soy has been reported to have a protective effect on the carcinogenesis of various tumors and to inhibit the growth of a wide variety of tumor cell in vitro. Angiogenesis is an essential process for the carcinogenesis, growth, invasion and metastasis of cancer and genistein has been suggested to act as natural anti-angiogenic agent. The purpose of this study was to evaluate the effects of genistein on the vascular endothelial growth factor (VEGF) expression in hamster buccal pouch oral carcinogenesis model induced by 9, 10-dimethyl 1,2-benzanthracene (DMBA). Experimental group that were supplied with 0.1mg/day genistein were sacrificed by time schedules and routinely processed for immunohistochemical examination of VEGF. In genistein treated group, carcinogenesis was retarded with respect to the acanthosis, hyperkeratosis, and epithelial dysplasia. Immunohistochemical study showed that the VEGF protein of genistein group was less expressed than that of the control group. (p<0.05) Thus, it is postulated that genistein has chemopreventive effect on the oral carcinogenesis, and this chemopreventive effect, at least partly, is originated from the anti-angiogenic effect of genistein

A 3-year-old, 38 kg, male Golden Retriever dog was referred to Veterinary Teaching Hospital of Konkuk University because of chronic formation of crust on nasal bridge and planum nasale. Abnormalities of physical examination included hyperkeratosis on the footpad, symmetrical alopecia and erythma around olecranon, and crust on nasal bridge and planum nasale. Results of the hematological examination showed a mild leukopenia with neutropenia, monocytosis, and mild lymphocytosis. In addition, the result of serum chemistry and thyroid gland profile were normal. Results of fungal and bacterial culture was negative. Acanthocytes in cytological evaluation of nasal crust were observed in direct microscopic examination. Examination of skin biopsy exhibited vacuolation of basal cell layer, degeneration and necrosis of basal cell with defluxion, mild monocytes filtrations between epidermis and dermis, and mild acanthosis with hyperkeratinization. Based on results of examination described above, Discoid Lupus Erythematosus (DLE) was diagnosed.
