The purpose of this study was 2-fold: 1) to investigate the prevalence of gastrointestinal parasite infection in cats reared in Daegu, Republic of Korea and 2) to assess the efficacy and safety of a topical emodepside/praziquantel formulation for cats with parasitic infections. The gastrointestinal parasite infections were examined microscopically using the flotation method. Of 407 cats, 162 (39.8%) were infected by at least one gastrointestinal parasite, including Toxocara cati (63.0%), Toxascaris leonina (31.5%), Taenia taeniaeformis (3.7%), and Cystoisospora felis (1.9%). None of the infected animals had multiple infections. When the data were analyzed according to sex, age, and type of cat, stray cats showed statistically higher prevalence than companion cats (P<0.05). On the 5th day after treatment, no parasitic eggs were detected using microscopic examination. In addition, no adverse effects, such as abnormal behaviors and clinical symptoms, were observed in the cats treated with the drug. These results quantify the prevalence of gastrointestinal parasites in cats in Daegu, Republic of Korea, and show that topical emodepside/praziquantel is a safe and effective choice for treating the parasitic infections in cats.

This study was designed to investigate the effects of 1-fluoro-2,4 dinitrobenzene (DNFB) on Induction of dermatitis in mice. We investigated the effects of DNFB on induction of dermatitis in terms of changes in body weights, ear thickness, ear weight, spleen/body ratio, histopathological observation and cytokine productions in inflammed tissue of contact dermatitis (CD) mice. In our experiments, we induced CD by using two different methods. First, mice were sensitized and challenged on the back of each ear (topical induction). Second, mice were sensitized on shaved back and challenged back of each ear (systemic induction). In our results, average weights were lowered in both topical and systemic group. But, there was no statistical significance between topical and systemic group. Treatment with DNFB enlarged ear weights and thicknesses in both topical and systemic groups. In addition, both groups were showed almost same features such as immune cell infiltration, spongiosis and hyperplasia in histopathological observations. Finally production levels of TNF-a, IFN-g and IL-6 were markedly elevated in both topical and systemic groups. On the other hand, systemic induction was more effective in spleen/body ratio and IL-6 production compared to topical induction respectively. These results suggest that dermatitis model using DNFB was used as model of CD, not for atopic dermatitis model.

Objectives: This study aimed to evaluate the effects of 5% lidocaine and 2.5% lidocaine/2.5% prilocaine topical anesthetic on pain during needle insertion and infiltration injection in the labial mucosa of anterior maxillary teeth, and to assess the relationship between patients' anxiety and pain scores. Materials and Methods: The Modified Dental Anxiety Scale questionnaire was applied and recorded. Patients were randomly divided into 4 groups (n = 30), as follows: G1 group: 5% lidocaine and placebo for 1 minute, G2 group: 2.5% lidocaine/2.5% prilocaine and placebo for 1 minute, G3 group: 5% lidocaine and placebo for 3 minutes, and G4 group: 2.5% lidocaine/2.5% prilocaine and placebo for 3 minutes. Before the application of topical anesthesia, one side was randomly selected as the topical anesthesia and the contralateral side as the placebo. The pain levels were measured with Visual Analog Scale (VAS) immediately after needle insertion and injection and were compared. The correlation between anxiety and pain scores was analyzed. Results: Administration of 5% lidocaine for 1 minute had significantly higher pain scores for both insertion and infiltration injection than the other groups (p < 0.05). There was a significant moderate positive correlation between dental anxiety and the injection-induced VAS pain score in the placebo side in all groups (p < 0.05). Conclusions: Topical anesthetics significantly reduced the pain caused by both needle insertion and injection pain in comparison to the placebo side. The pain scores of patients with dental anxiety were lower on the topical anesthesia compared to the placebo side.

This study was performed to examine the antibacterial efecacy of topical agent extracted from Phellodendri cortex, Forsythia fructus and Glycyrrhizae radix as an alternative dermatological agent. Also, the most efficacious concentration of this agent and the skin-contact time inhibiting the vegetation of bacterial cells in various dilutions were determined. Five strains of Staphylococcus intermedius were exposed to various dilutions of this agent. The efficacy was assessed after exposure for time periods varying between 0 and 30 min. The antibacterial efficacy was shown to be the strongest at dilution of 1: 2. The number of viable organisms decreased significantly after 8 minutes of exposure time and was the smallest after 30 minutes of exposure time. This alternative dermatological agent is considered to be effective against Staphylococcus intermedius and has a potential to be a new topical agents far the treatment of pyoderma in dogs.

Single subcutaneous administration to S.D rats of both sexes was performed to investigate the acute toxicity of Syndella gel, a new topical drug containing deproteinised dialysate of calf's blood and micronomicin sulfate. $LD_{50}$ values for S. D rats were 23,047 mg/kg for male and 23,725 mg/kg for female. The death occurred within 24 hours after administration at doses over 19,200 mg/kg. The main cause of death seemed to be respiratory disturbance by acute shock. Major general symptoms induced by injection subcutaneously with Syndella gel were underactivity, decreased respiratory rate, salivation, tremor and loss of consciousness. No significant body weight changes and gross findings of internal organs in treatment groups in comparison with those of control groups was observed at any dose levels in Syndella gel.

Graft-versus-host disease (GVHD) is frequent complications of hematopoietic stem cell transplantation. In the chronic GVHD (cGVHD), the oral cavity is the most commonly affected region. The clinical manifestations include erythema, ulceration, lichenoid-hyperkeratotic change in oral mucosa, dry mouth, and limitation of mouth opening. The initial treatment strategy of oral cGVHD patients is topical corticosteroid therapy in various formulation. However, corticosteroid resistance appears in some patients. We report a case of a 25-year-old male patient with oral cGVHD, who has resistance to topical corticosteroid medication, treated with 0.03% tacrolimus ointment and low-dose doxycycline. The patient showed subjective and objective improvement without side effect.

We examined the effect of topical application of Shimotsu-to, a traditional Chinese herbal prescription, on carrageenin-induced edema in rats and ultraviolet radiation-induced erythema in guinea pigs. Shimotsu-to (5% in water) markedly suppressed an acute edema of rat hindpaw induced by 1% carrageenin, and was more effective than any other single crude drug componcent of Shimotsu-to, Topical treatment with this prescription also inhibited ultraviolet erythema on the back skin of guinea pigs (a human sunbrun model). These results suggest the therapeutic effect on acute inflammation by topical application of Shimotsu-to.

Onychomycosis is the most common disease of the nail, with a worldwide prevalence of 5.5%. It causes local pain, paresthesia, and cosmetic problems and decreases the patients' quality of life. Conventional treatments include the administration of topical and systemic agents. However, factors such as subungual hyperkeratosis and biofilm formation may affect the efficacy of these treatments. Moreover, side effects associated with systemic agents are a major concern for patients. Therefore, various novel treatments are being developed; among them, photodynamic therapy (PDT) and Nd:YAG laser are promising, and several studies have demonstrated the efficacy and safety of PDT and laser therapy. Here, we report the efficacy and tolerability of PDT combined with 1064-nm Nd:YAG laser therapy and topical efinaconazole for the treatment of three patients with refractory onychomycosis.

This study was conducted with 60 adult males who visited the Atomi Cooperative Clinic(Atomi Dermatology/Pediatrics/Oriental Clinic) in Seoul between May 2003 and December 2004; they were divided into three groups, each of which consisted of 20 persons, according to the level of erythma and then each group was subdivided to consist of ten according to whether they received skin treatment and care. The standard care provided to two groups involved topical steroids and oriental medicines prescribed by a dermatologist and a oriental doctor, respectively. 5th-grade topical steroid ointment was applied to the face and 3rd-grade to the limbs; a oriental medicine was administered in a lukewarm state half an hour after meals three times a day. To determine how special and systematic skin treatment and care was helpful in treating atopy, a skin treatment system was applied to the experimental group while the control group was provided with standard care alone. By using Mexameter(MX18) manufactured by ck-mpa as a measuring tool, the inflammation level was observed at the right antecubital space during each visit to the clinic. In view of the re suits, introduction of the systemic skin care for A. D to legitimate treatment provided by a medical institution is expected to be an appropriate supplementary treatment for adult patients who suffer from frequent recurrence of atopic dermatitis.

Exposure to UVB radiation can cause diverse biological photodamage to skin. Eeb 761 and Korean red ginseng are the major and most effective natural drug against a variety of oxidative damage. But, the protective effects against UVB radiation have not been clearly identified. In this study, we investigated the protective effect of topical EGb 761 and Korean red ginseng on pigmentation by UVB radiation. Pro-inflammatory cytokines($IL-l{\beta}$, IL-6 and $TNF-{\alpha}$) and melanogenesis proteins(tyrosinase, TRP-1 and TRP-2) mRNA were measured by reverse transcription-polymerase chain reaction(RT-PCR) analysis. The in vivo protection against pigmentation was calculated using chromameter. The mRNA level of IL-lf and TNF-a were increased by UVB irradiation in treated and non-treated group, while no significant changes were observed in IL-6 level. Topical treatment with EGb 761 and Korean red ginseng remarkably reduced expression of tyrosinase, TRP-1 and TRP-2 in the non-irradiated and irradiated skin. Application of EGb 761 and Korean red ginseng significantly protected the WB-induced skin pigmentation and Korean red ginseng was more effective. Our study suggests that topical ECb761 and Korean red ginseng can regulate melanogenic proteins and protect UVB radiation on skin pigmentation.
