Objective: To examine the effects of Tribulus terrestris L. (T. terrestris) extract on the modulation of calcium channels to evaluate its use in topical agents for treatment of atopic dermatitis. Methods: The 70% methanol extract of T. terrestris was prepared. Human HEK293T cells with over-expressed calcium release-activated calcium channel protein 1 (Orai1), transient receptor potential vanilloid 1, or transient receptor potential vanilloid 3 (TRPV3) were treated with T. terrestris extract. Modulation of ion channels was measured using a conventional whole-cell patch-clamp technique. Results: T. terrestris extract (100 mg/mL) significantly inhibited Orai1 activity in Orai1-stromal interaction molecule 1 co-overexpressed HEK293T cells. In addition, T. terrestris extract significantly increased the TRPV3 activity compared with 2-Aminoethyl diphe-nylborinate (100 mmol/L), which induces the full activation of TRPV3. Conclusions: Our results suggest that T. terrestris extract may have a therapeutic po-tential for recovery of abnormal skin barrier pathologies in atopic dermatitis through modulating the activities of calcium ion channels, Orai1 and TRPV3. This is the first study to report the modulatory effect of a medicinal plant on the function of ion channels in skin barrier.

OBJECTIVE: To review recurrence and prognosis of microivasive squamous cell carcinoma of the cervix that are associated with depth of invasion, pathologic finding and management(conservative or radical treatment) STUDY DESIGN: We conducted retrospective study in order to evaluate the results of therapeutic approaches in 46 patients with microinvasive cervical cancer from Jan 1987 to Oct 1996. RESULT: The mean age of patients was 44.6+ 8.86 years. Only one woman was nullipara, and the mean parity was 2.8, Overall diagnostic accuracy of pap smear and punch biopsy were 54.3% and 79.4%. As the depth of invasion was deeper, the diagnostic accuracy of punch biopsy increased(p<0.05), The confluence pattern and lymphovascular space involvement were observed in 39.1% and 4.9%. The confluence pattern was observed with statistical significant in advanced depth of stromal invasion. In the surgical management, vaginal hysterectomy was done in 28 patients, conization(l patient), total abdominal hysterectomy(8 patients) and radical hysterectomy with pelvic lymph node dissection(9 patients) was done, no positive node was in 104 pelvic lymph node dissected. Though all cone margin was free and all endocervical curettage was negative, residual lesion(2 patients) was present in the hysterectomy after conization, The median follow-up period was 64 months. There was no recurrence in all cases and 5 years survival rate was 100% CONCLUSION: We suggest that microinvasive carcinoma of the cervix may be the disease of good prognosis and no recurrence, and less radical therapy for the patients with microinvasive carcinoma may be sufficient.

The stomach is the most frequent site of gastrointestinal stromal tumor (GIST). The common clinical manifestation of GIST are melena and hematochezia caused by gastointestinal bleeding. However, hemoperitoneum due to GIST rupture is a very rare condition. We describe a 33-year-old man with gastric GIST causing hemoperitoneum. A preoperative CT scan demonstrated large amount of fluid collection and extraluminal mass lesion in gastric antral area. He underwent an emergent laparotomy. The antral mass was polypoid shaped and showed ruptured focus. We performed a distal gastrectomy. The tumor was revealed as GIST with intermediate malignant risk by pathologic examination. The patient had an uneventful postoperative course and remains well.

Acute scrotum is any pathologic condition of the scrotum or intrascrotal contents that requires emergency medical or surgical management. Management of each disease entity is different, but the differential diagnosis is very difficult. So many testes were lost due to delay of the adequate diagnosis or unnecessary explorations had been taken under the misdiagnosis. A study was done to evaluate the differential diagnostic value of clinical symptoms and signs, physical examinations, laboratory data and radiologic studies including scrotal Doppler ultrasonography on acute scrotum patients. During the two years, thirty patients were visited to emergency medical center of Ajou university. There were 5 patients with testicular torsion, 16 acute epididymitis, 5 orchitis, 3 edema of scrotum, 1 infected hydrocele, the mean age of total patients was 17 years old. Symptoms and signs, laboratory data showed no specific ability to differentiate each disease entities, but radiographic evaluations were useful to differentiate testicular torsion from non-torsion acute scrotum. We could suggest that scrotal Doppler ultrasonography is useful for early differential diagnosis of the acute scrotum, especially in emergency department.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

Multiple cerebral aneurysms in children are rare lesions, occurring at a frequency of approximately 0.5% to 4.6%. In children, infective endocarditis from congenital or rheumatic heart disease are the important causes of cerebral mycotic aneurysms. Subarachnoid hemorrhage, most commonly caused by the rupture of an intracranial anurysm is associated with mortality and morbidity. We reported a case of multiple cerebral aneurysms in a 7 year old child with ventricular septal defect (VSD) in operation of the two times performed under general anesthesia. He was scheduled for elective surgery for clipping of cerebral aneurysm in ASA physical status II. For premedication, he was administered triflupromazine 10 mg (Veprin ) and glycopyrrolate 0.1 mg IM 1 hour prior to induction. Induction was established with thiopental, vecuronium after preoxygenation. N2O/O2 (2 L/min:2 L/min), isoflurane and vecuronium were administered for maintenance. For monitoring, ECG, direct arterial pressure, CVP, ETCO2 were performed. In second operation, we were performed the general anesthesia the same as the first operation. He had discharged in coma state on 4 day after the second operation hopelessly.

Malignant eccrine poroma, or eccrine porocarcinoma, is a rare malignant cutaneous appendageal tumor arising from the intraepidermal eccrine sweat duct(acrosyringium), and usually develops ia an eccrine poroma of long-standing. We report a case of malignant eccrine poroma on the left buttock in a 72 year-old female. She was presented with a slightly pruritic, well-defined, reddish, firm, 4.5 x 4.5 x 0.7cm sized, protruding, ulcerated tumor. Histopathological examination revealed well-defined tumor cell nests in the epidermis and dermis. The tumor nests consisted of areas of eccrine poroma cells with benign appearance adjoining areas of anaplastic cells. Duct-like structures were observed within the tumor nests and showed a PAS-positive, diastase-resistant reaction. On immunohistochemical staining, the tumor cells were, positive for EMA, and most of tumor cells were negative but the duct-like structures were positive for CEA. She was treated with surgical excision. During the three year follow up period after excision, there was no recurrence.
