Xanthomonas axonopodis pv. glycines(Xag) is a pathogen that causes bacterial leaf pustule(BLP) disease in soybeans grown in Korea and the southern United States. Typical and early symptoms of the disease are small, yellow to brown lesions with raised pustules that develop into large necrotic lesions leading to a substantial loss in yield due to premature defoliation. After Xag infects PI 96188, only pustules without chlorotic haloes were observed, indicating the different response to Xag. To identify differentially expressed genes prior to and 24 hr after Xag inoculation to PI 96188 and BLP-resistant SS2-2, an oligonucleotide macroarray was constructed with 100 genes related to disease resistance and metabolism from soybean and Arabidopsis. After cDNAs from each genotype were applied on the oligonucleotide macroarrays with three replicates and dye swapping, 36 and 81 genes were expressed as significantly different between 0 hr and 24 hr in PI 96188 and SS2-2, respectively. Six UniGenes, such as the leucine-rich repeat protein precursor or 14-3-3-like protein, were selected because they down-regulated in PI 96188 and up-regulated in SS2-2 after Xag infection, simultaneously. Using tubulin and cDNA of Jangyeobkong(BLP-susceptible) as controls, the oligonucleotide macroarray data concurred with quantitative real-time RT-PCR(QRT RT-PCR) results in most cases, supporting the accuracy of the oligonucleotide macroarray experiments. Also, QRT RT-PCR data suggested six candidate genes that might be involved in a necrotic response to Xag in PI 96188.

Tests of stability and toxicity, and clinical evaluation of anti-acne activity suggest that cryptotanshinone, a constituent of the roots of Salvia miltiorrhiza Bunge, is an effective active ingredient for acne vulgaris treatments. Acne vulgaris, called acne or pimples, is the most common disease of the pilosebaceous follicle unit of the skin. It affects nearly 80% of people between the ages of 11 and 30. Approximately 30% of teenagers have acne of sufficient severity to require medical treatment. Acne is a follicular disorder of the skin. It occurs in specialized pilosebaceous units on the face and body. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules and nodules). An abnormality of keratinizing epithelium of these follicles, thought to be due to the action of sebum synthesized and secreted by the androgen-sensitive sebaceous glands, leads to inflammation induced by the follicular bacterium Propionibacterium acnes. Therapy involves treatments that modify these pathogenic factors and includes drugs with antikeratinizing, antibacterial and antiseborrheic actions. Acne vulgaris is a very frequent disease, seen primarily in adolescents, involving the sebaceous follicles. Acne vulgaris is characterized by a great variety of clinical inflammatory and non-inflammatory lesions: comedones, papules, pustules, nodules, cysts and scars. Acne vulgaris is a multi-factorial disease. Although its pathogenicity is unclear, extensive studies have shown that hyperseborrhea, superinfection by P. acnes and endocrinologic androgenic changes play a role in the development of acne vulgaris.

Background: Acute generalized exanthematous pustulosis (AGEP) is typically a medication-induced acute febrile eruption. Few large-scale studies have reported clinical data regarding AGEP in Korea. Objective: This study analyzed the clinical and histopathological features of AGEP in Koreans to identify recent trends in this context. Methods: This study retrospectively reviewed 31 patients with AGEP. Age, sex, clinical features, etiologies, laboratory findings, histopathological features, and treatment outcomes were obtained from patients' medical records and photographs. Results: The mean age of onset was 43.6 years, and the male : female ratio was 2.1 : 1. All patients showed non-follicular tiny pustules and erythema. Fever was reported in 13 patients and neutrophilia in 17 patients. Medications were considered the most common etiological contributors. Twenty patients showed drug-induced AGEP, and 11 of 20 patients showed antibiotic-induced AGEP. Serum C-reactive protein and lactate dehydrogenase levels increased in 93.8% and 77.8% of the patients, respectively. Histopathologically, all patients showed subcorneal or intraepidermal pustules, followed by exocytosis and neutrophilic dermal infiltrate. Twenty-five patients improved within a mean period of 7.5 days after the onset of the skin rash. The percentage of women in the drug-induced AGEP group was significantly higher than that in the non-drug-induced AGEP group. Conclusion: This report describes a large-scale study that analyzed the clinical and histopathological features of AGEP in Koreans and seems to accurately reflect the recent trends in this context. Clinically, it is important to note that the percentage of women in the drug-induced AGEP group was higher than that in groups showing other etiologies of AGEP.

Objectives : This experiment study was performed to investigate the anti-inflammation and anti-oxidant effects of Indigo Naturalis(IN) and Rehmanniae Radix(RR) which were herbs for clearing heat. Methods : Anti-inflammation and anti-oxidation effects of IN and RR that were measured by the inhibitory ability of Nitric oxide(NO) production and the scavenging for 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical. Results : 1. IN and RR groups were not showed cell toxicity. 2. In the inhibitory ability of NO production, IN groups were better than RR groups, but there were no statistical significances among the groups. 3. In the scavenging for DPPH radical, IN groups were better than RR groups, but there were no statistical significances among the groups. Conclusions : These results showed that the IN group was better than the RR group in treating skin eruptions, especially those such as erythema, purple spot, papule, pustules which appear in acute inflammation.

Acne, which intrucdes the pilosebaceous unit, is a chronic inflammatory disease. The symptom of comedones, papules, pustules, cysts, nodules and scar mainly raises on the face, upper back, shoulder and neck. The cause of acne is the secreting growth of sebum, abnormal follicular keratiniziation, the form of group of propionibacterium acnes, and the respones of inflammation etc. But the original mechanism of the cytobiologic level is exactly not known yet. We treated three patients suffered from acne with acupuncture, venesection, Chungsangbangpung-tang, wet dressing with Gamihwangryunhaedok-tang. After treatments we observed the improvement. Based on this study, it is considered that acupuncture, venesection, Chungsangbangpung-tang wet drssing with Gamihwangryunhaedok-tang can be applied to the management of acne.

A 12-year-old female Tammar Wallaby (Macropus eugenii) died after a 6-day history of depression, anorexia, and coughing. The necropsy revealed pustules of varying sizes on the lung surface from which a pure culture of Staphylococcus aureus was isolated. Histopathologically, the pulmonary nodules formed typical granulomatous inflammation. The center of the granulomatous foci consisted of a necrotic center and grain particles with gram positive cocci that were surrounded by eosinophilic club-like bodies containing Splendore-Hoeppli material. To our knowledge, this is the first report of aspiration pneumonia with respiratory botryomycosis as a result of grain inhalation in a Tammar Wallaby.

Subcorneal pustular dermatosis (SPD) is a rare pustular skin disorder of dogs. Dapsone is treatment of choice, but ineffective in some cases. Therapeutic alternatives are limited and less effective. In humans, successful results with oral retinoid have been reported. To describe successful treatment of a dog that developed SPD with acitretin as an alternative drug of dapsone. A 7-year-old male neutered miniature schnauzer was presented with generalized pustules and crusts. SPD was diagnosed based on physical, cytological, and histopathological examination with direct immunofluorescence test. In this report, we describe a case of canine SPD treated initially by dapsone with poor response that improved with acitretin. Acitretin could be considered as an alternative drug in canine SPD.

Acne vulgaris is a common inflammatory skin disease of the pilose-baceous unit. It appears as lesions consisting of comedones, papules, pustules, and nodules of varying shapes and severity. In general, the first-line treatment for acne vulgaris includes topical and oral medication. Recently, various physical modalities have also been investigated. The use of laser therapy is steadily increasing because of its fewer side effects, short procedure time, and rapid results. In particular, laser therapy assisted with carbon suspension application is effective for acne vulgaris but may sometimes result in discomfort due to odor and dust formation during the procedure. Herein, we report that acne vulgaris and enlarged facial pores can be safely and effectively treated with laser therapy assisted with diamond particle suspension and gold microparticle application, which can address the discomfort caused by the carbon suspension application.
