The present study has been undertaken to investigate the effect of the extract of Cirsium japonicum var. ussuriense leaves (CLE) on blood circulation in a rat model of topical ferric chloride ($FeCl_3$)-induced carotid artery damage. $FeCl_3$ treatment seriously damaged the carotid artery such as the walls of the artery, blood flow and inflammation. However, CLE administration has ameliorated blood circulation and suppressed vessel inflammation. CLE administration also has ameliorated the $FeCl_3$-induced artery tissue damage. Furthermore, CLE significantly suppressed the expression of adhesion molecules. These results suggest that CLE ameliorate blood circulation through suppress inflammatory mediator and adhesion molecule production.

Submucosal infiltration and the topical application of epinephrine as a vasoconstrictor produce excellent hemostasis during surgery. The hemodynamic effects of epinephrine have been documented in numerous studies. However, its metabolic effects (especially during surgery) have been seldom recognized clinically. We report two cases of significant metabolic effects (including lactic acidosis and hyperglycemia) as well as hemodynamic effects in healthy patients undergoing orthognathic surgery with general anesthesia. Epinephrine can induce glycolysis and pyruvate generation, which result in lactic acidosis, via ${\beta}2$-adrenergic receptors. Therefore, careful perioperative observation for changes in plasma lactate and glucose levels along with intensive monitoring of vital signs should be carried out when epinephrine is excessively used as a vasoconstrictor during surgery.

Objective: Artificial insemination plays an important role in genetic improvement in the goat farming system. The aim of this study was to investigate the effect of cervical application of hyaluronan (HA) on the fertility in goats after cervical artificial insemination using frozen-thawed (F-T) semen. Methods: After oestrous synchronisation with progesterone sponges and pregnant mare serum gonadotropin injection, both nulli- and multi-parous goats, were randomly allocated to 2 groups, and were inseminated with 0.25 mL of F-T semen (150×106 spermatozoa) twice at 52 h and 56 h after sponge removal. Prior to the insemination, goats in Group 1 only were given topical cervical HA application at 48 h after sponge removal. Site of insemination was recorded as os-cervix or intra-cervix or intra-uterus. Pregnancy was tested ultrasonographically 42 days after insemination. The data on pregnancy rates and percentage of animals according to the site of semen deposition were compared by Chi-square analysis. Results: The overall pregnancy rate was significantly (p<0.004) higher in goats with prior application to the cervix with HA (63.3%) than without (36.0%). Same pattern was observed in the pregnancy rates of nulli- and multi-parous goats in both the groups. Percentage of nulliparous goats according to the site of insemination in the HA group did not differ between first and the second insemination. However, in multiparous goats the percentage of animals inseminated intra-cervically was significantly increased (p≤0.05) between the first and the second inseminations. Conclusion: The results suggest that significantly higher fertility rate in the "HA goats" compared to the "without HA" group was because of deeper insemination facilitated by topical cervical application of HA. The deeper insemination into the cervical canal increase the rate of fertilisation when the cervical artificial insemination is performed.

Perforating granuloma annulare (PGA), a rare variant of granuloma annulare, is characterized by transepidermal elimination of altered collagen that clinically manifests an umbilicated papule with a central crust. It can be confused with papulonecrotic tuberculid (PNT) because of their similar appearance. Unlike PGA, PNT is usually related to tuberculosis infection with a typical histologic finding of wedgeshaped dermal necrosis. Here, we report the first Korean case of PGA mimicking PNT both clinically and histologically. A 43-year-old Korean woman presented with erythematous papules localized on the extensor surface of her limbs for one year. Some of these papules had a central umbilication or a crust. Regarding comorbidity, she had latent tuberculosis diagnosed with $QuantiFERON^{(R)}-TB$ Gold test about five months ago. She was on antituberculous medication. Initially, a diagnosis of papulonecrotic tuberculid accompanied by latent tuberculosis was considered. However, despite taking the antituberculous medication for five months, her skin lesions were not improved. Biopsy specimen from her arm lesion showed wedge-shaped area of necrosis in the dermis. Additionally, there were multiple focal mucin depositions and palisading granulomatous inflammation throughout the dermis. A diagnosis of PGA was made and she was treated with topical corticosteroid. After two weeks of applying topical corticosteroid, most of her skin lesions disappeared, leaving some hyperpigmented scars.

Allergic contact dermatitis is an inflammatory condition associated with periorbital erythema, edema, and pruritus. The periorbital skin is relatively thin compared with the skin over other facial areas; therefore, it is vulnerable to allergen penetration and may show a variety of cutaneous manifestations. Recently, vision enhancement surgery is a widely performed procedure, and the prevalence of senile cataract and glaucoma is increasing. The prevalence of periocular allergic contact dermatitis is increasing secondary to the growing use of topical ophthalmic medications. Several studies in Korea have reported periocular allergic contact dermatitis secondary to the use of topical ophthalmic medications including latanoprost ($Latano^{(R)}$), fluorometholone ($Tolon^{(R)}$), polymyxin B ($Terramycin^{(R)}$), atropine sulfate ($Atropine^{(R)}$), neomycin sulfate ($Cambison^{(R)}$), and befunolol hydrochloride ($Bentos^{(R)}$), among others. However, ofloxacin ($Effexin^{(R)})$-induced allergic contact dermatitis has not been reported in the domestic and/or foreign literature. We report a case of periocular allergic contact dermatitis secondary to the use of ofloxacin ophthalmic ointment.

The aim of this study was to evaluate the efficacy of a topical 0.2% hyaluronic acid (HA) preparation in the management of wound after removal of arch bar for facial bone fracture and a suture site after orthognatic, oral cancer or oral surgery. Forty patients participated in a randomized, placebo controlled, double-blind trial to evaluate the efficacy of the topical HA and preparation. HA topically applied to the wound after removal of arch bar or stitch out, 3 times a day for 4 weeks. Evaluation is performed once a week for 4 weeks. For subjective evaluation, relative pain reduction in visual analog scale (VAS) and existence of heat sensation was accessed. For objective evaluation, gross evaluation, papilla index, existence of wound dehiscence, redness and swelling was checked. The same evaluation was performed in each arch bar group and suture group. For whole subject, 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy. Same findings were seen other weeks but there was no significancy. 0.2% HA group had better result than placebo in objective evaluation (papilla index, wound dehiscence, redness and swelling), but in gross evaluation placebo had better result than 0.2% HA group with no significancy. Subject was divided into suture group and arch bar group. Same aspect was seen, but only suture group had significancy not arch bar group in pain reduction score. 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy, especially in suture group. It reveals topical application of HA in wound especially suture site reduced pain in early stage. And 0.2% HA group had better result than placebo in papilla index, redness and swelling with no statistical significancy. In conclusion, HA has effect of pain reduction and healing promotion in the mucosal wound after oral surgery.
