BACKGROUNDS/AIMS: Although recent advances in surgical techniques and alternative treatment, the long-term survival >5 years after liver resection for hepatocellular carcinoma (HCC) is still unsatisfactory due to the high recurrence rate compared with other solid organ cancers. This study was conducted to analyze long-term survival after HCC resection and to develop an optimal strategy to achieve long-term survival. METHODS: A retrospective review was performed for HCC patients who underwent liver resection between 1996 and 2006. The survival rates and prognostic factors were assessed. The clinical and pathological factors of patients who survived more than 5 years were compared with those of patients whose survival was less than 5 years. The clinicopathological features characterizing long-term survivors were also reviewed. RESULTS: The overall and disease-free 5-year survival rates of 87 cases were 38.5% and 29.4%, respectively. Twenty-seven of 87 patients survived longer than 5 years after liver resection. The univariate analysis revealed that hepatitis C, the serum aspartate sminotransferase (AST) level, liver cirrhosis, Edmondson-Steiner grade, AJCC stage, and vascular invasion were significant factors for overall survival, and serum AST level, liver cirrhosis, Edmondson-Steiner grade, AJCC stage, and vascular invasion were the affecting factors for disease-free survival. In multivariate analysis, serum AST level, hepatitis C and vascular invasion were related with the overall survival, liver cirrhosis and vascular invasion which were associated with disease-free survival. Vascular invasion, AJCC stage, and the Edmondson-Steiner grade were significant factors in long-term survivors. CONCLUSIONS: Patients without liver cirrhosis, vascular invasion and normal liver function, good differentiation and an early stage may be expected to have a long-term survival.

The goal of fracture treatment is to restore the patient to pre-injury function level. But the outcome assessment after orthopedic interventions has usually focused on physician-defined parameters of technical success, such as fracture union, alignment and range of motion rather than patient function and quality of life. However, the correlation among improvements in these parameters and functional status, psychosocial well being is inconsistent and weak in the elderly. Therefore authors assessed the functional status after surgical intervention of hip fractures in the elderly with functional recovery score(FRS). Independence in basic activities of daily living, in instrumental activities of daily living, in mobility, freedom from pain and intact memory were assessed in 133 hip fractures in the elderly. The hip fractures in the elderly resulted in 24.8% loss of function after the first year. The older the age, the more the loss of function after surgery of hip fractures. The more functional loss was observed in female patients and in patients with poor postoperative radiological results, but statistically insignificant (P>0.05). The more functional loss was observed in patients with underlying medical disease preoperatively and it was statistically significant (P<0.05). We recommend the evaluation of functional status in the elderly after hip fractures.

Marchiafava-Bignami disease(MBD), characterized by the primary degeneration of the corpus callosum, is a rare complication of chronic alcoholism. Recently, a few cases of MBD with reversible neuro-imaging abnormalities were reported. A 58-year-old, chronic alcoholic man was admitted with mental change, dysarthria, and a seizure attack. A T2-weighted Brain magnetic resonance imaging demonstrated high signal intensities in the body and splenium of the corpus callosum, multiple white matter, and cortical gray matter. Treatment with a multiple vitamin complex resulted in a near complete recovery of neurological manifestation. A brain MRI obtained four weeks after admission revealed a dramatic resolution of previous imaging abnormalities. We report a case of Marchiafava-Bignami disease with reversible neuro-imaging abnormalities.

The purpose of this study was to examine the effects of anti-sperm antibody (ASA) on the fertilization processes using conventional IVF and ICSI procedure in human and hamster oocytes. In human IVF, we have observed restricted fertilization with sperm testing positive for ASA. (23~90% IgA, 60-97 % IgG). However, if ICSI was perform in the next IVF cycle with the same patients, we could successfully fertilize the oocytes (37%; p<0.001), thus achieving pregnancy and delivery. When the sperm were cocultured in medium containing ASA, there were binding of ASA to sperm surface. In addition, the mean rate of the acrosomal reaction in an in vitro acrosome reaction test was lower for Ab-bound sperm (43.5%) than for Ab-free sperm group (51.3%, p<0.05). We used human sperm and hamster oocytes to confirm the negative effects of the ASA on fertilization. The sperm and/or oocytes have been expose to medium containing ASA before IVF and ICSI. In this experiment, the ASA was bound to the oocyte and sperm surface. The following results were obtain by using various combinations of ASA free or ASA bound sperm with ASA free or ASA bound oocytes for IVF. When ASA free sperm were inseminate with ASA free and ASA bound hamster oocytes, the fertilization rates are 89.6% and 74.3% respectively. However, when ASA bound human sperm were use the results were 62.5% and 55.6% respectively. These shows the fertilization rate was significantly decreased in both ASA bound and ASA free oocytes when using ASA bound sperm. No difference found when ASA are present on the oocyte surface. When the hamster oocytes was treated by ICSI with ASA free or ASA bound human spermatozoa, no significant difference was found. These results showed that ICSI is the most promising method for couples who fertilization was not possible by conventional IVF because of ASA.

OBJECTIVES: The present study was designed to investigate the effect of ginseng saponin and its major active metabolite on the HPA axis under acute stress-i.c.v. injection stress, and immobilization stress, and to examine whether nitric oxide is involved in the mechanism of ginseng saponin on the HPA axis under acute stress. METHODS: In the experiment to study the effect of ginseng on HPA axis during stress, various dose of GTS were injected intracerebroventricularly(i.c.v.) or intraperitoneally(i.p.). Plasma corticosterone levels were measured 30 min after the i.c.v. injection stress. Immobilization stress was applied for 30 min and then blood was cellected for the assays of plasma corticosterone levels immediately after the completion of immobilization stress. To determine the active ginsenosides that can affect the stressinduced plasma corticosterone levels, various dose of each gisendosides(Rb1, Rb2, Rc, Re, Rf, Rg1, 20(S)-Rg3, and 20(R)-Rg3) were injected i.c.v. or i.p.. In the experiment to determine the involvement of the nitric oxide in the inhibitory effect of ginseng on the HPA, NG-Nitro-L-arginine methyl ester(L-NAME) and ginsenosides were coadministered i.c.v. or i.p., and plasma corticosterone levels were measured 30 min after stress was applied. RESULTS: First, the present study showed that ginseng total saponin, ginsenoside Rg3(S form), and ginsenoside Rc administered i.c.v. attenuated the intracerebroventricular injection stress-induced increase in plasma corticosterone levels, and these effects were removed by nitric oxide co-injection. Second, ginseng total saponin and ginsenoside Rc administered i.p. attenuated the immobilization stress-induced increase in plasma corticosterone levels, but ginsenoside Rg3(S form) did not attenuate the immobilization stress-induced increase in plasma corticosterone levels. The attenuative effects of ginseng total saponin and ginsenoside Rc in the immobilization stress-induced increase in plasma corticosterone levels were not affected by L-NAME co-injection. CONCLUSION: This study suggests that ginseng saponin attenuated stress-induced increase in plasma corticosterone levels and these effects were mediated by different mechanisms according to the components of ginseng saponin, and routes of administration.

Cerebral Vasospasm was produced experimentally by injecting normal cat's blood into the cisterna magna of the cat. Ultrastructural changes were observed sequentially from 24 hours to 15 days following subarachnoid hemorrhage(SAH). Twenty-four hours after SAH, endothelial cells in the intima were round shaped and their cellulrar surface was corrugated, these changes remained to 72 hours after SAH with intimal thickening and loss of tight intercellular junction. But since 7 days after SAH, the endothelial cells assumed a more normal spindle-shaped configuration with tight intercelluar junction and an increase in cytoplasmic filaments and vacuoles. The internal elastic laminae was thickened and somewhat more electron dense than normal. In the media, the smooth muscle cells were most consistently and severely affected showing degeneration of mitochondria, vacuoles containing fine particles and loss of complex internal structure, surrounded by increased amounts of intercellular collagen. These findings concluded that the ultrastructural changes in the cat's basilar arterisl wall observed after induction of subarachnoid hemorrhage with fresh autogenous blood occurred as a consequence of vasospasm.

Four cases of intracerebral hemorrhage remote from the site of initial supratentorial craniotomy are presented. Traumatic cases are excluded in this report and all cases developed after uneventful elective craniotomy. Two patients had ruptured aneurysm and the other two had giant supratentorial tumors, one craniophayrngioma and one ependymoma. All patients were operated on supine position and no patient had preoperative hypertension. Two had hematoma in the sucortical white matter, one in the cerebellar hemisphere and the other one showed hematoma both in the cerebellar hemisphere and the supratentorial subcortical area. The size of hematoma ranged from 8-20cc in volume. No definite cause could be found except one in which the blood pressure was transiently elevated during induction of anesthesia. A possible cause might be the sudden changes of blood pressure during induction and recovery from anesthesia, overdrainage of CSF, continuous CSF drainage and sudden changes in intracranial dynamics by removal of a huge intracranial mass. One patient with intracerebellar hemorrhage needed emergency suboccipital craniectomy for removal of the hematoma. One patient shows no improvement due to aspiration pneumonia and subsequent lung abscess. Although rare, these conditions may occur after any craniotomy and surgeons should always be alert to the possibilities of such comlication, especially when intracranial pressure(ICP) was elevated.

PURPOSE: Hepatic resection and liver transplantation are considered a curative treatment for hepatocellular carcinoma (HCC) within the Milan criteria. In this study, we examine the outcome of hepatic resection for HCC within the Milan criteria, and determine the effectiveness of hepatic resection as the primary treatment for HCC within the Milan criteria in Child-Pugh class A. METHODS: 110 patients underwent curative surgical resection for HCC in Child-Pugh class A between August 1991 and June 2008. Fifty-six patients met Milan criteria (Group M) and the remaining 54 did not (Group N). RESULTS: Overall survival rates at 1, 3, and 5 years were 92.6%, 72.5% and 54.6% versus 70.4%, 43.1%, and 28.7% in Group M and Group N, respectively (P=0.0043). The corresponding disease-free survival rates were 81.5%, 69.7%, and 38.2% versus 46.0%, 32.9%, and 26.9% in Group M and Group N (P=0.0012). HCC recurred in 25 patients in Group M (44.6%) and 35 patients in Group N (64.8%)(P=0.034). Outcomes of hepatic resection in Group M were significantly better compared to Group N. CONCLUSION: Hepatic resection can achieve a comparable 5-year overall survival & disease-free survival to that reported for liver transplantation. Hepatic resection should be considered as the standard therapy for HCC within the Milan criteria in Child-Pugh class A patients.
