This study was attempted to know that the interactions of various fungi, and methionine and MgSO4 introduced as the substrate of culture media for fungi were affected to produce aflatoxins by Asp. flavus. 5 different fungi were isolated from the fermented soybean mash and were cultured in Chemically Defined medium (C.D. media) and soybean mash at 25 degrees for 10 days. (1) It was confirmed that Asp. flavus produced aflatoxins in the C.D. medium and soybean mash, but that Asp. niger, Asp. oryzae, Asp. awamori and Asp. terreus did not produced them respectively. (2) Asp. flavus cultured with Asp. niger did not produce aflatoxins in C.D. medium, but produced in soybean mash, in other hand, Asp. flavus with other fungi except Asp. niger produced aflatoxins in C.D. medium and soybean mash. (3) The growth of fungi were more prosperous in the separate culture than in the mixed culture. (4) In the C.D. medium added 20% of cultured medium of Asp. niger, Asp. flavus did not produce aflatoxins but other cultured medium did not prohibit the production of aflatoxins by Asp. flavus. (5) On the contrary, MgSO4 increasing the productivity of aflatoxins by Asp. flavus in the C.D. medium methionine known as one of precurser of aflatoxins did not affected the increasing productivity with significance.

In order to evaluate the value of vertebral angiography in assessment of hemifacial spasm, we reviewed retrospectively the vertebral angiography of 28 patients(30 cases) with surgically proved hemifacial spasm but normal CT scans of posterior fossa. There were 9 males and 19 females. Angiography revealed vascular focus of hemifacial spasm located at anterior inferior cerebellar artery, posterior inferior cerebellar artery, and vertebral artery in 19, 9, and 2 cases respectively. Right side was involved in 20 cases. All involved vessels were elongated, tortuous, and dilated. In conclusion, vertebral angiography was valuable in evaluating hemifacial spasm of vascular origin in the posterior fossa.

A propecive analysis of 50 patients with acute interhemisphric subdural hemorrhage and tentorial hemorrhage, an unusual pattern of acute subdural hematoma, who were managed in a uniform way was analyzed to related outcome to hemorrhagic site, initial Glasgow Coma Scale(GCS) and combined injuries. The incidence of acute interhemisphric subdural hemorrhage(ISH) and tentoria hemorrhage(TH) after head trauma was 3.83%, 50 cases among 1303 head injured cases. And 80% of the above hemorrhage disapperaed within two weeks after trauma. There was no significant relationship between feature of hemorrhage and intial GCS(P>0.05), but there was highly significant relationship between initial GCS and Glasgow Outcome Scale(GOS) (p<0.001). There noted significant relationship between initial combined injury and GOS(p<0.01), and also brainstem injury and GOS(p<0.001).

7.The Effect after Intra-dermal Methylene Blue, Hydrocortisone, Lidocaine Injection Therapy for Intractable, Idiopathic Pruritus Ani.
Journal of the Korean Society of Coloproctology 2005;21(2):71-75
PURPOSE: Idiopathic pruritus ani is a common and embarrassing proctological condition which can be very difficult to treat. In this study, we documented our results with methylene blue intra-dermal injection in patients with intractable idiopathic pruritus ani. METHODS: 5-ml 1% methylene blue, 100-mg hydrocortisone, and 15-ml 1% lidocaine were injected into the perianal skin of 21 patients with idiopathic pruritus ani which had proved refractory to standard care. Clinical follow-up was undertaken. RESULTS: After one injection of the above solution, 15 (71.4%) of the patients were rendered symptom free. Repeat injection in the initial non- responders ultimately rendered another four. 19 (total: 90.5 %) of the patrents symptom free. Morbidity was 0%. CONCLUSION: This study has shown that intra-dermal methylene blue injection is a safe, simple, and efficient method of treating intractable, idiopathic pruritus ani.

8.Randomized Trial Comparing a Starion(TM) and a Harmonic Scalpel(TM) Hemorrhoidectomy.
Journal of the Korean Society of Coloproctology 2009;25(1):8-13
PURPOSE: The present study was designed to evaluate the efficacy and the outcome when using the Starion(TM) and the Harmonic Scalpel(TM) vessel sealing systems for a sutureless hemorrhoidectomy. METHODS: This study is a randomized, controlled trial. Patients with Grade 3 and 4 hemorrhoids were categorized into two groups: the Starion(TM) hemorrhoidectomy (30 patients) group and the Harmonic Scalpel(TM) hemorrhoidectomy (30 patients) group. The measures of the primary outcomes were the operating time, the postoperative pain score, and the patient satisfaction score. Secondary outcome criteria included early and delayed complications: postoperative bleeding, anal stenosis, urinary difficulty, and skin tag. RESULTS: The satisfaction scores 4 wk postoperatively were not significantly different between the two groups (P=0.186). However, the operating time was reduced (P=0.019), the pain score was lower (P=0.009), and the satisfaction score 1 wk postoperatively (P=0.001) was lower in the Starion(TM) hemorrhoidectomy group. In addition, there were no differences in early and delayed postoperative complications between the two groups (all P>0.05). CONCLUSION: Both methods were found to be surprisingly equivalent in all major aspects analyzed. A Starion(TM) hemorrhoidectomy with submucosal dissection can provide a safe, fast, bloodless, reduced-pain, and low-priced surgical alternative to hemorrhoidal surgery. More studies are needed to determine whether similar favorable results can be attained in patients with more severe, strangulated hemorrhoids.

We have experienced two cases of extramammary Paget's disease. The first case was a 68-year-old male who showed erythematous, crusted, oozing, eczematoid patches on the scroturn, penile root and pubic area, and verrucous plaque on the left pubic area of 5 years' duration. The second case was a 60-year-old male who showed erythematous, oozing, hyperkeratotic plaque and nodular mass on the scrotum of 4 years' duration. In electron microscopic findings of the first case, the Paget's cells was suggested to be formed by pleuripotential germinative cells; well developed microvilli, numerous electron lucent secretory granules, a few electron dense granules, apocrine type secretion and well developed desmosome.

A poor prognosis of oral squamous cell carcinoma (SCC) is partly due to the invasiveness and metastasis of the tumor. A key element in tumor invasion and metastasis in the degradation of extracellular matrix is matrix metalloproteinases (MMPs). This study was performed to determine the expression of MMP-2 and MMP-9 of oral SCCs with regard to the histologic invasiveness and differentiation in 5 normal oral mucosa and 36 oral SCCs. The histologic invasiveness of oral SCCs were classified into 4 grades. The differentiation of oral SCCs was divided into 3 grades. The streptavidin-biotin immunohistochemical staining, using MMP-2 and MMP-9 monoclonal antibodies, was performed to determine the expression of MMP-2 and MMP-9. The expression of MMP-2 was positive in 6 of 17 oral SCCs with weak invasiveness and was positive in 7 of 19 oral SCCs with strong invasiveness. The MMP-2 expression did not increase significantly with respect to the invasiveness of oral SCCs (P>0.05). The expression of MMP-9 was strongly positive in 6 out of 17 SCCs with weak invasiveness and was strongly positive in 14 of 19 SCCs with strong invasiveness. The MMP-9 expression increased significantly with respect to the invasiveness of oral SCCs; the stronger the expression, the stronger the invasiveness (P<0.05). The expression of MMP-9 was in 57.9% of well differentiated SCCs, 57.1% of moderately differentiated ones, and 33.3% of poorly differentiated SCCs. The expression of MMP-2 and MMP-9 did not increase significantly with respect to the histologic differentiation. We conclude that with respect to the invasiveness, the MMP-9 expression increases significantly in oral SCCs but the MMP-2 expression does not; and that with respect to the histologic differentiation, their expressions do not increase significantly. These results suggeste that MMP-9 can be used as a tool to evaluate the invasiveness of oral SCCs.
