Many carcinomas have an active mononuclear cell infiltrates surrounding tumor. Various in vitro assays have shown that cellular constituents of peripheral blood mononuclear cells(PBMC) can alter growth of carcinoma cell line. Author compared the effects of normal fibroblasts on squamous cell carcinoma cell line(SCL-1) along with those of sctivated and/or nonactivated PBMC on SCI 1 using a skin equivalent system. This system prevents direct cellular contact by growing SCL-1 on an overlying Millicell-HA membrane and normal fibroblast or supernatants of PBMC in a lower chamber. Normal fibroblasts enhanced the outgrowth of SCL-1 and induced a more organized phenotype of SCL-1. Supernatants from nonstimulated PBMC suppressed outgrowth of SCL 1, and concanavalin A stimulated PBMC supernatants alterd rnorphology of cultured SCL-1 from a disorganized phenotype to a more organized phenotype. It is concluded that fibroblasts and PBMC may affect the growth and differentiation of SCL-1 via their mediators(cytokines)

Hypothalamic hamartomas are often associated with early onset gelastic seizures, precocious puberty,
behavioral problem and suboptimal response to antiepiletptic drugs. Until now, four surgical options
have been reported to reduce seizure by >50%. Surgical excision have good seizure outcome but
postoperative complications were not infrequent, whether by pterional or transcallosal interforniceal
approach. Radiosurgery is noninvasive alternative to resective surgery but the effect usually does not
appear until several months later. Radiofrequency ablation is less invasive than surgical resection and
its effect is immediate, but lacks long term follow-up data. It also requires three dimensional analysis of
the lesion to enhance effi cacy and safety. As hypothalamic hamartoma is intrinsically epileptogenic and
epileptogenic discharges spread from the lesion, blocking the seizure propagation through endoscopic
disconnection is regarded as an effective and safer option. Surgical choice for a particular patient
should take into account the hamartoma’s size, location, surgeon’s preferences, possible complication
as well as the effect and risk of the various surgical methods. In the present review, open surgery,
endoscopic disconnection, radiosurgery and radiofrequency ablation are discussed.

PURPOSE: Bile acids (especially deoxycholate) was known to be toxic and mutagenic on colon epithelium. They proposed at least four mechanisms for the bile acid toxicity. It is the one of these mechanisms that bile acid inhibits the xenobiotic metabolizing enzyme activity (esp glutathione S-transferase, GST). So we measured the cytosolic GST level of colon carcinoma cell lines after deoxycholate exposure whether or not the deoxycholate lowered the cytosolic GST activity. METHODS: Three colon cancer cell lines (LoVo, SW480, HT29) were used for this study. We calculated the cellular toxicity by MTS method. And cytosolic GST activity was measured according to the method as Habig described. For total GST activity, 2.5 mM 1-chloro-2,4-dinitrobenzene was used for substrate, and measured as absorbance in 340 nm. RESULTS: Basal cytosolic GST level for LoVo, SW480, HT29 cell line was 514.59+/-27.01, 291.63+/-38.44 and 344.58+/-47.92 nmol/min/mg cytosol protein. GST level did not changed significantly after 5 days culture without DCA. But GST level was decreased significantly to 128.63+/-21.35, 134.33+/-41.76 and 163.10+/-22.73 nmol/min/mg cytosol protein each cell line after 5 days deoxycholate exposure (p<0.005). CONCLUSION: Cytosolic GST level was lowered significantly after deoxycholate exposure for 5 days. One of the mechanisms of bile acid toxicity for colon cancer cell is proposed to inhibit cytosolic GST activity.

BACKGROUND: It is understood that amylase is poor and lipase is a little better than amylase in specificity for the diagnosis of acute pancreatitis. But we recognized that the general knowledge was resulted from the study of inappropriate design of some researchers. So, we tried to find out the true diagnostic value of amylase and lipase by the study of appropriate design, and with the above result, evaluated the usefulness of lipase as a diagnostic test for acute pancreatitis. METHODS: We reviewed the serum levels of the amylase and lipase in 33 patients complaining acute abdominal pain diagnosed as acute pancreatitis by image study (computed tomography, ultrasonography) , and in the 134 patients of control group who, with abdominal pain, were diagnosed finally as non-pancreatic disease at discharge after admission and treatment. Serum amylase and lipase activity were measured by aca IVTM (Chiron Inc.). RESULTS: The sensitivity of amylase and lipase for the diagnosis of acute pan creatitis was 81.8% and 87.8%, respectively. The specificity of amylase and lipase for the diagnosis of acute pancreatitis was 92.5% and 86.5%, respectively. The sensitivity and specificity was 84.6% and 96.3% respectively, when two enzymes were combined by 'and' strategy. The lipase activity remained elevated longer than the amylase in acute pancreatitis. CONCLUSIONS: On the contrary of the general knowledge, sensitivities and specificities of the amylase and lipase were fairy high and didn't show big dirt ferences between two enzymes. Though only one of the two enzymes could be selected for the diagnosis of acute Pancreatitis, using both of the enzymes increased the specificity, and lipase was useful to detect the patient who came to hospital a few days later after the onset of symptom.
