Local anesthetics produce pain during infiltration into skin. The relationship between local anesthetic-induced pain and pH of the local anesthetic solution has not been fully investigated. Commercial preparation of local anesthetics are prepared as acidic solutions of the salts to promote solubility and stability. And the acidity of local anesthetic solition may be related with the pain during infiltration of the solutione. So, we tried to neutralize the lidocaine hydrochloride solution which is one of the most frequently used local anesthetic agent. Sodium bicarbonate was used for neutralization. Sodium bicarbonate was mixed with lidocaine hydrochloride until the resulting pH of the solution become 7.4 which is identical to the acidity of body fluid. To identify the effect of neutralized lidocaine solution, we had a course of double blind test to 6 volunteers. Both forearm of each volunteer were injected with neutralized lidocaine and plain one and the degree of pain was estimated by each volunteers. According to subjective description by the volinteers, everyone felt neutralized lidocaine injection site was less painful than plain lidocaine. We concluded that we could reduce pain from infiltration of lidocaine hydrochloride by neutralization of the anesthetic solution with sodium bicarbonate.

Paget's disease is classified, according to location, as mammary or extramammary disease. Extramammary Paget's disease especially in the vulva is extremely rare. Several hundred cases have been described worldwide. Patients with Paget's disease of the vulva are usually white and postmenopausal. The cause of which remains elusive. A case of vulva Paget's disease is presented with brief review of literature.

OBJECTIVE: To evaluate whether the rate of early mouse embryonal development could be enhanced by cumulus cell coculture in vitro. METHODS: Ham's F-10 culture media supplemented with 0.4% bovine serum albumin were used. Two-cell F1 mouse embryos were cultured in media with or without cumulus cells of female ICR mouse embryo for 96 hours, and the rates of embryonal development were observed and compared. RESULTS: The percentage of hatched blastocyst in the coculture group was significantly higher than that in the control group by 87.3% vs 64.8% respectively (p< 0.05). CONCLUSION: This study provides confirmative information that cumulus cell coculture will be useful in enhancing early mouse embryonal development.

Cytomegalovirus (CMV) is a major cause of morbidity and mortality in immunocompromised patients. CMV can cause pneumonia, retinitis, gastrointestinal ulcers, and widely disseminated disease, but cutaneous CMV is rare. We report two cases of cutaneous CMV infection presenting as perianal ulcers. A 54 year-old male who had liver transplantation and a 72-year-old male, who was treated with chemotherapy for angioimmunoblastic T-cell lymphoma, presented with perianal ulcers and had systemic symptoms of CMV infection with CMV antigenemia. They had multiple ulcerations with erythematous bases on the perianal area, and histopathologic examinations showed large atypical cytomegalic cells in the dermis, and immunohistochemical stains, with the anti-CMV antibody showed positive reactions.
