Despite advances in surgery, radiotherapy, and chemotherapy, the survival of patients with oral squamous cell carcinoma has not significantly improved over the past several decades. Gene therapy is currently under investigation and shows us new possibility of cancer curing method. This experiment was undergone to find out the cell growth inhibition effect and evidence of apoptosis by HCCS-1(human cervical cancer suppressor-1), one of the candidates of tumor suppressor gene, transducted to human oral cancer cell line. To determine the efficiency of the adenovirus as a gene delivery vector cell line was transducted with LacZ gene and analysed with X-gal staining. Northern blot was performed to confirm the transfection with HSCC-1 gene and cell viability was assessed by cell cytotoxicity assay using cell count kit(CCK). To show the evidence of apoptosis, DNA fragmentation assay and flow cytometry(FACS) were performed. We had successfully construct the recombinant HSCC-1 adenovirus(Ad5CMV-HCCS-1), and importation efficiency was 20% at 2 MOI(multiplicity of infection), 80% at 20 MOI. Northern blot analysis showed that a single 0.6kb mRNA transcript was expressed in Ad5CMV-HCCS-1 transducted cell lines. As a result of CCK, when comparing to control subjects, transducted group showed 50% growth inhibition. In DNA fragmentation assay, according to increasing of MOI, DNA volume was diminished. In FACS analysis, DNA distribution showed fragmentation.This results imply that HCCS-1gene has growth inhibition effect in human oral cancer cell lines through apoptosis induction.

STUDY DESIGN: The authors retrospectively analysed the recovery of clinical symptoms after surgical treatment of lumbar HIVD. OBJECTIVES: To investigate the incidence of clinical symptoms, the recovery rate and time after surgical treatment and the difference between L4-5 and L5-S1 lesion. SUMMARY OF LITERATURE REVIEW: There are many reports concerning the clinical result of surgical treatment for the HIVD. They usually describe the result as excellent, good, fair and poor. We can't get any information about the recovery rate and recovery time of each clinical symptom from the reports . MATERIALS AND METHODS: Thirty-eight patients were treated by one level open discectomy from march 1991 to december 1995, The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR and severity of radiating pain were periodically followed up on the predesigned protocol. RESULTS: In preoperative examination, SLR was positive in 82%, motor deficit in 76%, sensory deficit in 74%, DTR change in 50%, and radiating pain in 100%. The recovery rate of SLR was 96.8%, motor deficit ; 93.6%, sensory deficit ,78.6%, DTR change ; 21% and radiating pain ,84.2%. The average recovery time of SLR was 3.4 months, motor deficit ; 1.9 months, sensory deficit ; 5.3 months, DTR change ; 4.1 months and radiating pain ; 3.2 months. Motor and sensory deficit was more frequent in L4-5 lesion but DTR change was usually noted in L5-S1 lesion. The recovery rate and time showed no great difference between the two level. CONCLUSIONS: The recovery rate was higher in SLR, motor deficit and radiating pain rather than sensory deficit and DTR change. The recovery time was fastest in radiating pain but variable nature was noted in sensory deficit. Above results may be helpful to explain the prognosis of the lumbar HIVD.

Kikuchi's disease usually occurs in young women and is characterized by localized lymphadenitis (mostly cervical) usually associated with fever. It is considered a self-limited disease and most patients recover spontaneously within a few weeks to 6 months without any serious sequelae. However, patients with Kikuchi's disease require a systemic survey and regular follow-up for several years because it may be associated with other diseases such as systemic lupus erythematosus. To our knowledge, there are very few reports of Kikuchi's disease accompanied by hemophagocytic lymphohistiocytosis. Biopsy of a right cervical lymph node in a 35-year-old female who presented with fever and masses in the right cervical region showed necrotizing lymphadenitis and a diagnosis of Kikuchi's disease was reached. She was started on methylprednisolone pulse therapy (500 mg for 3 days) but developed generalized rash and fever. Laboratory data showed pancytopenia, elevation of serum transaminase and ferritin levels. Bone marrow and liver biopsy showed proliferation of histiocytes and Kupffer's cells engulfing lymphocytes, platelets and red blood cells, respectively. We report a case of Kikuchi's disease accompanied by hemophagocytic lymphohistiocytosis.
