Investigations of the anti-tumor activity of recombinant mouse TNF and etoposide(VP-16) in a nude mouse subcutaneous implantation xenograft model utilizing the CURC-1 human renal cell carcinoma cell line were performed. Recombinant mouse tumor necrosis factor-alpha(rTNF-alpha) and VP-16. both well known cytotoxic and cytostatic anticancer agents were evaluated singly and in combination against subcutaneously growing CURC-1. The results were as follows : 1. In the absence of treatment(Group I). subcutaneously growing CURC-1 tumor nodules demonstrated continued rapid growth. 2. Administration of rTNF(Group II) induced significant tumor regression in the subcutaneous nodules. 3. Administration of rTNF and Etoposide(Group III) demonstrated significant tumor growth inhibition. On histopathological findings, Group I (control) shows rare leukocyte infiltration and no tumor necrosis. In contrast, Group II shows tumor necrosis and more leukocyte infiltration than Group I . Group III demonstrates tumor necrosis. tumor cell degeneration and more leukocyte infiltration than Group II. These results suggest that TNF have antineoplastic effect against subcutaneous human renal cell carcinoma nodule but the synergistic effect of TNF with VP-l6 is uncertain.

Nerve-root anomalies are very uncommon, and there symptoms and signs are nearly similar with those of disc herniation. So we can misdiagnois them for intervertebral disc herniation. The negative Lasegue' sign is the only distinct feature of the nerve root anomalies. The authors report a case of Nerve-Root Anomaly associated with disc herniation in lumbar 4-5 interspace, which was diagnosed preoperatively in myelogram and confirmed surgically.

The intracranial epidural abscess is a not indenpendent disease which is practically always secondary to osteitis or osteomyelitis of overlying bone. Also it was developed from complication of frontal sinusitis, middle ear or mastoiditis, incomplete debridement of compound comminuted depressed fracture and post-operative complications. Occasionally it was derived from dural sinus thrombophlebitis especially cavernous sinus. It was frequently developed frontal and temporal region. We have experienced 5 cases of intracranial epidural abscesses for this one year. Followings are the results ; 1. The causes were complication of compound depressed fracture, chronic osteomyelitis and post-operative complications. 2. The usual symptom was headache, fever and increased lethargy. 3. The laboratory findings of CBC were the increased WBC count and ESR. The CSF findings revealed occasionally increased the cell count and sugar. 4. The pus culture revealed proteus, coliform bacilli and paracolon bacili. 5. Treatment was surgical removal of overlying diseased bone, drainage of the purulent materials and instillation of antibotics irrigation. 6. The prognosis of the 5 cases of the intracranial epidural abscess was good. There was not appeared any complication or sequelae.

Encapsulated and free pus in the substance of the brain tissue following an acute purulent infection is known as brain abscess, and which is uncommon. The brain abscess arise either as direct extention from infections within the cranial cavity or as hematogenous metastasis from infections elsewhere in the body. Since 1945, the antibiotics associated use of steroid and mannitol have been available for the treatment of brain abscess, and the result are very hopeful. The common method of surgical treatment are consist of excision and drainage and the problem of the best operative procedure has been disputed on the many neurosurgical literatures for many years. Recently we had treated 2 cases of severe otogenic brain abscesses with semicomatose patient by drainage, and good was the result compared with the other literatures. Result; 1. One case with semicoma recovered completely without any neurologic sequelae, and the other case recovered with visual disturbance. 2. The best operative procedure for the severe brain abscess considered a drainage.

Translocations leading to fusions between the immunoglobulin heavy chain gene (IGH) and various partner genes have been reported in B-cell precursor acute lymphoblastic leukemia (B-ALL). However, submicroscopic deletions within IGH in B-ALL have not been rigorously assessed. In this study, we investigated characteristics of IGH submicroscopic deletions, by FISH, in B-ALL with IGH rearrangements. FISH was performed by using commercially available IGH dual-color break-apart rearrangement probes (Abbott/Vysis, Downers Grove, IL, USA; Kreatech, Amsterdam, Netherlands). The study group included seven B-ALL patients with IGH rearrangements, observed by FISH. Among them, two exhibited deletion of the 5' variable region of IGH by FISH. The B-ALL in these two patients included two kinds of abnormal cells; one had an IGH rearrangement without any IGH submicroscopic deletion, while the other had an IGH submicroscopic deletion, which showed that one normal fusion signal and one 3' IGH signal were detected. Thus, submicroscopic deletion of the IGH 5' variable region may have occurred in either the native or rearranged chromosome 14. These findings indicate that B-ALL with IGH rearrangements may be accompanied by submicroscopic deletions of the IGH 5' variable region, which can be detected by FISH. The clinical significance of such deletions is unclear, but the loss of part of the IGH gene in B-ALL warrants further study.

PURPOSE: The primary goal of palatoplasty is to enable normal speech with harmonious growth of face. Some children who had palatoplasty display typical findings of transverse maxillary deficiency requiring orthodontic widening of the maxilla. Levi (2009) described a cleft palate repair coupled with pedicled buccal fat pad flaps to cover bone exposed areas of the hard palate. Hence we report clinical experiences of cleft palate repair using pedicled buccal fat pad flap. METHODS: Four Veau class II and a Veau class I cleft palate patients underwent palatoplasty with buccal fat pad flap by single surgeon from April 2009 to August 2009. Two patients received 2-flap palatoplasty and three patients 1-flap palatoplasty, respectively. After the cleft palate repair, sharp mosquito scissors was placed in the superior buccal sulcus just lateral to the maxillary tuberosity and inserted directly through the mucosa resulting in buccal fat pad extrusion. The elevated flap was moved to cover mucoperiosteal defect in hard palatal area. RESULTS: Five patients underwent primary palatoplasty using buccal fat pad flap. Flap harvest and inset took on average 9 minutes per flap. Mucosal epithelization took 18 days on average. No patients had complications related to the buccal fat pad flap. CONCLUSION: Buccal fat pad pedicled flap has significant potential to function as an added vascularized tissue layer in cleft palate repair and we can expect better growth of maxilla with this method although longer duration of follow-up was unavailable.

The majority of metastatic lesions involving the skull arise from carcinoma of the breast and lung. Bone metastass from a wide speculum of malignant neoplasms may be discussed in general as osteoblastic or osteoclastic in type. In osteoblastic from there are carcinoma of the prostate, carcinoma of the breast, carcinoma of the urinary bladder and rarely hypernephroma and cholangiocellular hepatoma. Osteoclastic metastass are characteristically produced by carcinoma of the lung, uterus, gastrointestinal tract, and thyroid and malignant melanoma, and rarely hepatocellular hepatoma, Osteoclastic or osteolytic lesions are much more frequent. Osteolytic metastass to the skull typically present as multiple radiolucenices with ill-defined margin. Metastases may affect any portion of the skull, not only the calvaria but also the base. Recently we experienced a rare case of metastatic hepatocellular carcinoma to the skull. A 51 year old Korean male was admitted to the Dept. of neurosurgery, on Jan. 18, 1975. Patient had complained of headache and mass on the right frontoparietal region for ca 6 weeks and motor weakness on the left extremities for 2 weeks prior to admission. No jaundice and weight loss were complained. The mass on the right frontoparietal region had increased its size gradually and showed adult fist in its size on admission. Neurological examination on admission disclosed that the adult-fist sized mass on the right frontoparietal region was non-tender and palpated soft, and deep tendon reflexes were hyperactive, on the left, and Lt. Superficial reflexes were diminished. No spasticity was noted, and left grasping power was markedly weak. Hypersthesia was felt on the left of the body. No icterus was found. Nor palpable liver neither spleen was found. No tenderness on the abdomen and no palpable masses were noted. Complete blood cell counting was normal. The blood chemistry including the liver function test revealed normal except increased alkaline phosphatase(10.5 Bodansky units). (-feto-protein was negative. Urinalysis and stool examination were normal. X-ray films of simple skull series revealed multiple radiolucencies with ill-defined margins on the right fronto-parietal bone. Right carotid angiograms showed the left square shifting of the right anterior cerebral artery to the left and compressed downward the Rt. Middle cerebral artery, and abnormal vessels in tumor mass were supplied by only the Rt. External carotid artery extracranially and intracranially. Liver scanning was normal. A decompression craniectomy was performed. Extracranially the tumor mass was brownish yellow and soft, which seemed to be the lipoma in character. The skull bone was destroyed multiply. Intracranilly same mass was found. They were removed totally without any bleeding. The operation was finished in usual way, and biopsy was attempted. The post-operative course was usual one except no recovery of the neurologic deficit for 2 weeks. Microscopic examination revealed a metastatic hepatocelluar hepatoma.

BACKGROUND AND OBJECTIVES: The basic principle of microdialysis is to mimic the function of a capillary blood vessel by perfusing physiologic liquid implanted into the target tissue. Amino acids are supposed to have functions for controlling the homeostasis of normal nasal mucosa and a role in the pathogenesis of allergic rhinitis. However, no studies have been conducted about the existence of amino acids in the nasal cavity. This study measures the concentration of 19 amino acids found in the nasal cavity of normal control and experimentally allergy-induced animal model in order to evaluate the difference in the concentration of amino acids between normal and allergic nasal mucosa. MATERIALS AND METHOD: An experimentally induced nasal allergy model was developed by intraperitoneal and intranasal sensitization with ovalbumin in Dunkin-Hartely guinea pigs according to a programmed protocol. A microdialysis probe was designed to be suitable to nasal mucosa using a Cuprophan hollow fiber (200 micrometer inner diameter, 300 micrometer outer diameter, 45 kDa molecular weight cut-off, Fitral, AN 69-HF). After verification of the probe, microdialysis was performed in the inferior turbinate submucosa of normal control (N=8) and experimental (N=8) groups. The concentration of 19 amino acids was analyzed using high performance liquid chromatography. Statistical analysis was performed using a student t-test. RESULTS: All 19 amino acids were validated at various concentrations in the nasal cavity. Glutamate (p=0.036) and GABA (p<0.001) concentrations were significantly higher in the experimental group than in the control group. CONCLUSION: The 19 amino acids measured existed in the nasal cavity at various concentrations, and the concentrations of glutamate and GABA were significantly higher in the allergy group than in the control group. The microdialysis technique is a powerful tool not only to measure endogenous substances for target organ chemistry but also to pharmacokinetically evaluate exogenous drug delivery processes in the nasal cavity.

Invasive aspergillosis has been increasing as the number of severe immunocompromised hosts rises. Particularly, in allogeneic hematopoietic stem cell transplantation (HSCT) recipients, incidence of invasive aspergillosis ranges from 4 to 10%. Even with appropriate treatment, the prognosis of invasive aspergillosis in allogeneic HSCT recipients remains poor, showing high mortality rate. Herein, we report a case where invasive aspergillosis in a patient with acute myelogeneous leukemia progressed to disseminated aspergillosis after allogeneic HSCT. A 31-year-old woman with acute myelogenous leukemia had invasive aspergillosis after third reinduction chemotherapy. After administering amphotericin B, the patient underwent the wedge resection of lung, and HLA-matched allogeneic HSCT was then conducted. On day 14 of transplantation, the patient died of disseminated aspergillosis, including possible cerebritis and endocarditis despite the amphotericin B therapy.
