Intravenous Patient Controlled Analgesia (IV PCA) after general or spinal anesthesia may be a method of postoperative pain control, but side effects such as nausea, vomiting, and sedation occurs in most patients. The following research is based on the ultrasound guided femorosciatic nerve block held on parts below the knee joint operation. Because this anesthesia is held locally on the sciatic nerve with continuous anesthesia performed through perineural catheterization, the complications of nausea, vomiting, and sedation may be reduced while postoperative pain caused by the sciatic nerve is controlled. The following report is held on this experience.

PURPOSE: The purpose of this study was to analyze the relationship between apoptotic index and clinicopathological findings in laryngeal squamous cell carcinomas. MATERIALS AND METHODS: Fourty-one cases of laryngeal squamous cell carcinomas were analyzed for the detection of apoptotic bodies by in situ hybridization. RESULTS: The average apoptotic index was 9.38+/-2.89. The apoptotic indices were 11.26+/-1.86, 8.17+/-2.55, and 4.32+/-2.41 in well differentiated, moderately differentiated and poorly differentiated carcinoma, respectively. The histopathological differences and apoptotic index were statistically significant(p<0.05). But there was no relationship between apoptotic index and T stage, nodal status, recurrence and treatment results. CONCLUSION: The apoptotic index was only related to cellular differentiation. Also these results suggest that the numbers of apoptotic bodies in the tumor tissues can make it possible to presume indirectly the malignant potentiality of the tumor and will help us to understand the biologic behavior of head and neck cancer.

PURPOSE: We evaluated the HPV type 16, 18 infection and p53 expression and MHC class Iantigen expression, and analyzed he relationship between HPV infection and p53 expression and MHC class I expression in laryngeal squamous cell carcinomas. MATERIALS AND METHODS: Thirty-nine cases of laryngeal squamous cell carcinomas and ten cases of laryngeal nodules were analyzed for detection of HPV DNA by in situ hybridization and the detection of p53 and MHC class I antigen by immunohistochemical technique. RESULTS: HPV DNA was detected in 10(26%), and p53 expression was detected in 19(49%) out of 39 cases in laryngeal squamous cell carcinomas. HPV positive cases showed 50% of p53 expression whereas HPV negative cases showed 48% expression. MHC class I down-regulation (heterogenous and negative expression) in HPV positive lesions was higher than HPV negative lesions, but there was no statistically significance. The expression of MHC class I was related to cellular differentiation regardless of T-stage and nodal involvement. CONCLUSION: There was no reiationship between HPV infection and p53 expression and MHC class I expression in laryngeal squamous cell carcinomas. Also these results suggest that MHC class I expression can make it possible to presume indirectly the malignant potentiality of the tumor.

BACKGROUND: The effect of spinal nitric oxide (NO) on mechanical allodynia brought about by Freund's complete adjuvant (FCA)-induced inflammation is not known. From our previous experiment nitric oxide synthase (NOS) inhibitor nitroG-L-arginine methyl ester (L-NAME) given intraplantarly during the induction period decreased a mechanical hyperalgesia occurring because of FCA-induced inflammation. Therefore, we investigated the spinal effect of NO on mechanical allodynia after the development of allodynia produced by FCA-induced inflammation in rats. METHODS: Male Sprague Dawley rats were prepared with lumbar intrathecal catheter implantation. Inflammation was induced in the rats by injecting 0.1 ml of FCA under halothane anesthesia. Behavioral tests were done 1, 3, 6, 24, and 48 hours after injection of FCA. In the other group, intrathecal L-NAME (10 microgram) was given prior to FCA injection to examine the effect of pretreatment. On postinjection day 2, either L-NAME (10 microgram) or methylene blue (10 and 30 microgram) was administered intrathecally after the baseline measurement. The withdrawal response on mechanical allodynia was assessed by applying von Frey filaments to the right lesioned hindpaw and contralateral paw (as control) at 15, 30, 45, 60, 90, and 120 minutes. Sodium nitroprusside was administered intrathecally to determine the reversal effect of increased threshold in the L-NAME group. RESULTS: Injection of FCA produced a significant mechanical allodynia over time. Pretreatment with L-NAME did not prevent such a mechanical allodynia. Intrathecal L-NAME, but not methylene blue, reduced the mechanical allodynia, which was reversed by sodium nitroprusside. CONCLUSIONS: Spinal NO is likely invloved in the mechanism of the development and maintenance of mechanical allodynia in a state of FCA-induced inflammation.
