To study the effect of anticancer drugs on the RESFunction, cyclophosphamide and 6-mercaptopurine were intramuscularly injected and evaluated the reticuloendotherial phagocytic activity by the carbon clearence method in rats. Experimental groups were subdivided by the dosage, into the small and large dosage groups, and by the duration of treatment, into the 1, 3, 5 days and 8days (3 days cessation after 5 days treatment) groups. The results obtained were as follow. 1. Cyclophosphamide-treated groups showed the splenic atrophy which was in proportion to duration of treatment. RES phagocytic activities seemed to be slightly increased in large groups, but to be within normal ranges in ranges in small dosage groups, which were normalized in the 8 days groups. 2. 6-Mercaptopurine-treated groups didn't show the hepatic and splenic alterations significantly. RES phagocytic activities were variably changed as in triphagic curve fashion in both small and large dosage subgroups of 1, 3, 5 days treated groups, which were normalized in the 8 days groups.

It is generally known that moyamoya disease is a disease showing typical angiographic findings such as bilateral stenosis or occlusion of the distal internal carotid arteries and the major branches with extensive parenchymal, leptomeningeal or transdural anastomosis. However, its etiology is still unknown. Chief clinical manifestations are transient ischemic attack, motor paresis, headache, altered mentality and seizure. Twelve angiographically proven cases of moyamoya disease in chonnam National University Hospital from 1983 to 1990 were analyzed with respect to clinical manifestations, findings of brain computed tomography, cerebral angiographic findings and outcomes. The results were as follows: 1) Sex ratio was 1:2 as 4 males to 8 females. 2) They were 2 juvenile form(aged 8-13 yrs) and 10 adult form(aged l9-59 yrs). 3) Transient ischemic attack(2 cases), hemiparesis (5 cases), headache(6 cases), altered mentality(4 cases), facial palsy(2 cases), aphasia(1 case) and neck stiffness(1 case) were shown as clinical anifestations. 4) In brain computed tomography, intraventricular hemorrhage(5 cases), intracerebral emorrhage(2 cases), subarachnoid hemorrhage(1 case), infarction(4 cases including 2 old infarction combined with hemorrhage), contrast enhanced tortuous moyamoya vessels only in brain base(1 case) and suprasellar tumor(1 case) were noted. 5) Brain magnetic resonance imaging was perfomed in 1 case. It revealed characteristic collateral vessels in brain base. 6) All cases showed the characteristic angiographic findings of moyamoya disease with different stage of the progression, In addition to moyamoya vessels, 2 cases of aneurysm and 1 case of diffuse internal carotid artery hypoplasia were found. 7) Some neurologic sequales were noted in two cases. One case expired due to recurret intraventricular hemorrhage.

Acute occlusion of the intracranial internal carotid artery (ICA) bifurcation, so-called "carotid T occlusion," extends from distal portion of the internal carotid into the proximal segments of the middle and anterior cerebral arteries. This carotid T occlusion has been associated with low recanalization rates and poor prognosis. An 83-year-old man underwent successful transarterial suction thrombectomy using manual compression of ipsilateral common carotid artery for the treatment of acute carotid T-occlusion. Herein, we report this case and discuss the technical aspect.

Extraskeletal Ewing's sarcoma is a very rare tumor which was first reported by Angervall and Enzinger in 1975. The common sites of extraskeletal Ewing s sarcoma are bony structures of lower extremities, paravertebral region, and pelvis, but rarely chest walL Microscopically, extraskeletal Ewing's sarcoma is indistinguishable from the Ewing's sarcoma of bone. We present here a case of extraskeletal Ewing's sarcoma of the left lateral chest wall in a 19-year-old male. Wide extirpation and postoperative combined chemotherapy were done, and we discuss the clinical picture, histopathology, therapeutic management, and prognosis with review of the literature.

PURPOSE: Garlic has anti-microbial and anti-inflammatory effects. We investigated its actions and preventive effects on chronic bacterial prostatitis (CBP) using a rat model. MATERIALS AND METHODS: Bacterial suspension was inserted into the prostatic urethra of 75 rats. Then 15 were grouped as garlic group, and 60 as control group. Garlic and saline were given to each group for 4 weeks, respectively. After partial resection of the prostate, microbiological culture and histological examination were done. The incidence of CBP was compared between two groups. To evaluate the anti-microbial and anti-inflammatory effect of garlic, the 41 rats proved as CBP models among the control group were divided into 4 groups randomly: I, control; II, garlic; III, ciprofloxacin; IV, garlic plus ciprofloxacin. After 3 weeks of treatment, microbiological cultures of urine, prostate and histological examination of prostate were done. RESULTS: In study of the preventive effects, 5 rats in garlic treatment group and 41 rats in control group were shown to be CBP models. In anti-microbial and anti-inflammatory evaluation, positive urine culture rate and prostate tissue show no significant difference among four groups, but bacterial growth in urine and prostate tissue were lower in groups II, III, and IV than group I. Bacterial growth was the slowest in prostate tissue of group IV. Histologic findings were more improved in groups II, III and IV than group I, with Group IV being the most improved. CONCLUSIONS: These results show that garlic has preventive and therapeutic effects on CBP. Combination treatment with antibiotics may be considered in the future.

Tailgut cysts (TGCs) are rare congenital cysts that occur in the retrorectal or presacral spaces. Although most tailgut cysts have been reported as benign, there have been at least 9 cases associated with malignant change. We report herein on an unusual case of a 40-year-old woman with a carcinoembryonic antigen (CEA) -producing adenocarcinoma arising within a TGC who underwent surgical resection and local radiation therapy. Despite the complete resection, metastatic adenocarcinoma developed five months after surgery. CEA-producing adenocarcinoma from a TGC is extremely rare and only two cases, including this case, have been reported in the English medical literature. Besides CEA, the serum levels of CA 19-9 became markedly elevated in this patient. Given that the serum CEA level decreased to the normal range after complete resection of tumor and that the tumor recurrence was associated with a rebound of the CEA serum level, our case shows that serial measurements of serum CEA can be used for treatment planning and for assessing the patient's treatment response for this rare disease.

Gene-modified replication-competent adenoviruses (Ads) are emerging as a promising new modality for the treatment of cancer. We have previously shown that E1B 19kDa and E1B 55kDa gene deleted Ad (Ad-deltaE1B19/55) exhibits improved tumor-specific replication and cell lysis, leading to potent anti-tumor effect. As an additional effort to increase cancer cell-selectivity of replicating adenovirus, we have first generated eleven E1A-mutant Ads (Ad-mt#1~#11) with deletion or substitution in retinoblastoma (Rb) binding sites of E1A. Of these viruses, Ad-mt#7 demonstrated significantly improved cytopathic effect (CPE) and viral replication in a cancer cell-specific manner. To further increase the cancer cell-specific killing effect of Ad-mt#7, both E1B 19kDa and E1B 55kDa genes were deleted, resulting in an Ad-deltaE1Bmt7. As assessed using CPE assay, MTT assay, and immunoblot analysis for Ad fiber expression, Ad-deltaE1Bmt7 exerted markedly enhanced cancer cell-specific killing effect as well as viral replication in comparison to either Ad-mt#7 or Ad-deltaE1B19/55. Furthermore, the growth of established human cervical carcinoma in nude mice was significantly suppressed by intratumoral injection of Ad-deltaE1Bmt7. In summary, we have developed an oncolytic adenovirus with significantly improved therapeutic profiles for cancer treatment.

BACKGROUND/AIMS: It has recently been reported that non-amidated gastrin is associated with the development of colon cancer. However it is not known whether amidated gastrin, atrophic gastritis, and the status of Helicobacter pylori (H. pylori) infection are related to colon cancer. The aims of this study were to determine whether plasma level of amidated gastrin is elevated in patients with colon cancer compared with controls and to determine whether H. pylori infection and/or atrophic gastritis affect the relationship between amidated gastrin and colon cancer. METHODS: Twenty-two patients with colon cancer and twenty-two controls were enrolled in this study and their plasma amidated gastrin titers were measured by 125I radioimmunoassay. H. pylori infection was determined by histology. The degree of mucosal atrophy was determined by Sidney classification. RESULTS: Amidated gastrin levels were not different between the patients with colon cancer and controls. The status of H. pylori infection did correlate with amidated gastrin levels. Antral mucosal atrophy was not also correlated with amidated gastrin levels, but there was a tendency (p=0.074). CONCLUSIONS: Amidated gastrin is not related to the development of colon cancer.

PURPOSE: The diagnostic criteria of gastric intraepithelial neoplasia (IEN) are controversial across the world. We investigated how many discrepancies occur in the pathologic diagnosis of IEN and early gastric carcinoma in endoscopic submucosal dissection (ESD) specimens, and evaluated the reasons of the discordance. MATERIALS AND METHODS: We retrospectively reviewed 1,202 ESD specimens that were originally diagnosed as gastric IEN and early carcinoma at 12 institutions. RESULTS: The final consensus diagnosis of carcinoma were 756 cases, which were originally 692 carcinomas (91.5%), 43 high-grade dysplasias (5.7%), 20 low-grade dysplasias (2.6%), and 1 others (0.1%), respectively. High- and low-grade dysplasia were finally made in 63 and 342 cases, respectively. The diagnostic concordance with the consensus diagnosis was the highest for carcinoma (91.5%), followed by low-grade dysplasia (86.3%), others (63.4%) and high-grade dysplasia (50.8%). The general kappa value was 0.83, indicating excellent concordance. The kappa values of individual institutions ranged from 0.74 to 1 and correlated with the proportion of carcinoma cases. The cases revised to a final diagnosis of carcinoma exhibited both architectural abnormalities and cytologic atypia. The main differential points between low- and high-grade dysplasias were the glandular distribution and glandular shape. Additional features such as the glandular axis, surface maturation, nuclear stratification and nuclear polarity were also important. CONCLUSION: The overall concordance of the diagnosis of gastric IEN and early carcinoma in ESD specimens was excellent. It correlated with the proportion of carcinoma cases, demonstrating that the diagnostic criteria for carcinoma are more reproducible than those for dysplasia.

"Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012" is a 2nd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 1st edition published in 2009. After 1st stroke rehabilitation CPG, many studies concerning stroke rehabilitation have been published and the necessity for update has been raised. The Korea Centers for Disease Control and Prevention supported the project "Development of Clinical Practice Guideline for Stroke Rehabilitation" in 2012. Thirty-two specialists in stroke rehabilitation from 18 universities and 3 rehabilitation hospitals and 10 consultants participated in this project. The scope of this CPG included both ischemic and hemorrhagic stroke from the acute to chronic stages. The purpose of this CPG is to provide guidelines for doctors and therapists to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. "Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012" consists of 'Chapter 1; Introduction of Stroke Rehabilitation', 'Chapter 2; Rehabilitation for Stroke Syndrome, 'Chapter 3; Rehabilitation for Return to the Society', and 'Chapter 4; Advanced Technique for Stroke Rehabilitation'. Both the adaptation and de novo development methods were used to develop this 2nd edition of CPG. The appraisal of foreign CPGs was performed using 'Korean appraisal of guidelines for research and evaluation II' (K-AGREE II); moreover, four CPGs from Scotland (2010), Austrailia (2010), USA (2010), Canada (2010) were chosen for adaptation. For de novo development, articles that were published following the latest foreign CPGs were searched from the database system, PubMed, Embase, and Cochrane library. Literatures were assessed in the aspect of subjects, study design, study results' consistency, language and application possibility in the Korean society. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. GPP (Good Practice Point) was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised.
