Hemangioma and vascular malformation is a common vascular benign lesion in the head and neck region. The lesion is a congenital malformation observed in neonates. The treatment this lesion includes surgical excision, cryotherapy, selective embolization and treatment with sclerotic agents. We present three cases of benign oral vascular lesions treated with an intralesional injection of sodium tetradecyl sulfate. The lesions virtually disappeared after three sessions of sclerotherapy, leaving an inconspicuous scar. No side effects were observed. Sclerotherapy with sodium tetradecyl sulfate is effective in treating benign oral vascular lesions, and the use of the sodium tetradecyl sulfate provides alternative or support for surgical methods.

Background: Hemangioma and vascular malformation are benign vascular lesions that often occur in cephalic and cervical region. Currently, surgical resection, laser therapy, angiographic embolization, use of steroids, and sclerotherapy are used as treatments. Case presentation: This study reports three cases of benign vascular lesions that are remarkably treated by sodium tetradecyl sulfate (STS) injection, of which occurred in oral cavity and around the mouth. Three percent of STS was diluted with 0.9 % of normal saline, and it was injected to the lesion site at least once. The result of treatment was evaluated based on clinical findings. Conclusion: Surgical treatment of hemangioma and vascular malformation occurred in oral cavity is not normally used because of esthetic issues and potential hemorrhage. On the other hand, sclerotherapy using STS is an effective therapy compare to surgical treatment. Despite the number of STS injection was different for each patient, all three patients had reached satisfactory level through the treatment with gradual diminution of lesions.

The change of interactions of anionic surfactants, sodium dodecyl sulfate(SDS) and sodium tetradecyl sulfate(575) in the presence of electrolytes, to the chitosan-based polyelectrolyte(sol＇n and gel phase) were studied. The chitosan gel used in this study were crosslinked with epichlorohydrin(ECH). Binding isotherms were determined by potentiometric technique using a surfactant ion selective solid-state electrode and the results were represented by using the sequence generating function(SGF) method. The results of binding isotherm were shown comparatively high cooperativity. The addition of electrolytes in the chitosan/SDS system resulted in a shift of the binding to higher free surfactant concentration because of screen effect by the electrolytes. Degree of binding of chitosan gel was higher than that of chitosan sol＇n. And also a conformational phase transition of the chitosan gel in the presence of electrolytes has been investigated.

Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity.

Cationic gemini-surfactant, namely 1,4-butane-bis(N-alkanoyloxyethyl-N,Ndimethyl)-diammonium bromide was synthesized and their inhibition effect on corrosion of mild steel in 1 M HCl solution was tested by weight loss method. The synthesized product was confirmed by FT-IR and $^1H-NMR$ spectroscopy. Surface tensions were measured by surface tensiometer Sigma 70. Their c.m.c. values evaluated by surface tension method was $4.1{\times}10^{-5}{\sim}5.4{\times}10^{-5}$ mol/L. The Krafft point of the these surfactants were <0~$10.7^{\circ}C$. The emulsifying properties of synthesized cationic gemini surfactants and sodium dodecyl sulfate (SDS), tetradecyl trimethyl ammonium bromide (TTAB) was investigated. Of these, 1,4-butane-bis(N-lauroyloxyethyl-N,N-dimethyl)- diammonium bromide, CGL 14-4-14 has been confirmed as a good emulsifier. The inhibition efficiency increases by increasing cationic gemini surfactant concentration. As a result, these surfactants are expected to be applied as corrosion inhibitors.

배경: 비록 경화요법이 정맥류를 치료하는데 확립된 방법일지라도 그 성공률에는 차이가 있다. 따라서 이 연구의 목적은 압박경화요법의 치료효과와 합병증을 평가하는데 있다. 대상 및 방법: 2000년 12월부터 2001년 9월까지 일차성 하지 정맥류 환자중 압박경화요법을 시행 받은 39명(50예의 하지)을 대상으로 하였다. 주사한 직후 정맥류의 경로를 따라서 탈지면롤을 댄 후, 다시 class II 압박스타킹을 신겼다. 환자는 치료효과와 합병증의 정도를 보기 위해서 시술후 5일, 1주, 2주, 6주에 평가되었다. 결과: 환자의 연령은 26세에서 66세까지로 평균 45.3세이었으며 여자 36명, 남자 3명이었다. 모든 환자에서 경화요법의 결과는 우수하였다. 50례의 하지 중 5례에서만 작은 합병증이 있었는데 2례의 혈관내 작은 응혈, 2례의 색소침착, 1례의 압박으로 인한 수포가 있었다. 이는 특별한 치료 없이 모두 회복되었다. 결론: 국소 압박도구로써 탈지면롤은 매우 손쉽고 효과적이며, 압박경화용법은 경제적 부담이 적고 안전하고 효과적인 치료법이다.

양이온 에스테르형 계면활성제인 N-2-hydroxy-3-(2-hydroxyacetoxy)proply-N,N-dimethyl dodecylaminium chloride (HPDA)를 합성하였고, FT-IR 과 $^1H$-NMR 분석으로 확인하였다. 합성화합물의 묽은 수용액에 대하여 표면장력을 측정하고, 임계미셀농도를 산정하였다. 표면장력은 $10^{-3}{\sim}10^{-2}mol/L$ 농도 범위에서 33~34 dyne/cm 이었고, 표면장력법에 의해 산정한 임계미셀농도는 $8.5{\times}10^{-3}mol/L$ 이었다. 합성 계면활성제인 HPDA와 SLS, TTAB의 유화특성을 시험하였다. 그 결과 HPDA가 우수한 유화제로 확인되었다. 그리고 Ross-Miles 방법으로 기포력과 기포안정성도 측정하였다.
