Sinusitis manifested as symptomatic imflammation of the paranasal sinuses is a common pediatric diagnosis. Many studies have focused more directly on the question of relationship between allergy and sinusitis but the relevance of the relationship between allergy and sinusitis still needs further examination, The purpose of this study is to assess of relationship of allergy to extent or severity of sinusitis. A clinical evaluation was performed on 199 children, age 2 to 15 years, in whom the diagnosis of sinusitis was confirmed by paranasal sinus radiographic assessment at our hospital Pediatric OPD and in the ward from July 1991 to June 1993. The results were as follows: 1) Male was more prominent than female (M:F ratio 1.76:1). The age distribution, 100 cases(55.2%) of the total case were 4-7 year old. 2) The symptoms were coughing, most common (77,9%), rhinorrhea, nasal discharge and nasal stuffiness, in decreasing order. The clinical signs were postnasal drip (62.8%), most common, throat injection, wheezing sound, and allergic shiner in decreasing order. Eighty eight patients were evaluated acute and compared with 111 patients with chronic sinusitis. 3) Comparable study between two groups were summarized as follwos: (1) There was no significant difference in age and sex distribution between acute and chronic group. (2) The lowest seasonal incidence of acute group was seen in summer and autumn but there was no significant variation between both group (p>0.05). (3) Allergc disease was more prevalent in chronc group than acute group (p<0.05). Asthma incidence was higher in chronic group than acute group (p<0.05). (4) The frequency of total IgE level checked by PRIST higher than 200 IU/ml in acute group and chronic group was 23.2% and 42.3%, respectively (p<0.05). The incidence of positive skin prick test in acute group and chronic group was 25.0% and 46.5% respectively (p<0.05). (5) Otitis media, nasal polyp and adenoid hypertrophy incidence were higher in chronic group than acute group (p<0.05). (6) There was no significant difference if ESR between both groups. The eosinophilia in peripheral blood higher than 5% in the acute group and chronic group was 15.9% and 42.3% respectively (p<0.05). (7) The patients with chronic group had more severe involvement of the paranasal sinuses than acute group (p<0.05). (8) There were no significant difference in chest radiographic findings and follow up paranasal sinus radiographic findings after treatment (P>0.05).

Primary biliary cirrhosis(PBC) is a chronic cholestatic liver disease of unknown origin. The small and medium sized intrahepatic bile ducts are destroyed by an inflammatory process, which, it has been suggested, is of the autoimmune type. It is strongly associated with the presence of antimitochondrial antibodies, predominantly IgM and IgG. The liver changes are classified into four stages, of which stage IV represents the development of cirrhosis, which required orthotropic liver transplantation in the longrun. The prevalence rates was reported 128 per millon in Sweden , but the disease is relatively rare in Oriental area. In medical treatment, long-term administration of ursodeoxycholic acid improves both clinical and biochemical signs, slows the progression of the disease and reduces the complication requiring liver transplantation. We report two cases of PBC, one with histologically proven cirrhosis, and the other with bile duct destruction consistent with stage III and hypothyroidism.

For 16 years after the finding of HIV as an agent of AIDS in 1981, HIV therapeutic drugs of reverse transcriptase inhibitors (AZT, ddI, ddC, d4T) and protease inhibitors have been developed. Recent studies also were focused on a combination therapy by using HIV therapeutic drugs or natural compounds. Korean red ginseng (KRG) of natural compounds has been well known as a good reinforcement agent in Asia. The percentage of CD3+CD4+ T cell in nine HIV-infected patients without KRG treatment averaged 17.8% on baseline and decreased 15.8% after 6 months, whereas the percentage of the cell in fifteen HIV-infected patients with KRG treatment averaged 15.3% on baseline and increased up to 18.9% after the same period. The average percentage of CD3+CD8+ T cell of KRG-nontreated and KRG-treated HIV patients increased after 6 months 47.8% to 50.7% and 44.7% to 51.4%, respectively; and the average percentage of B and NK cell in the KRG-nontreated and KRG-treated HIV patients decreased 9.4% to 7.9% and 13.0% to 9.7%, 8.9% to 8.5% and 16.2% to 11.6%, respectively, KRG, therefore, didn't have any effects on the CD3+CD8+ T cell, B cell, and NK cell. However, it seems that KRG has a potential activity for stimulating the

PURPOSE: To evaluate the early clinical results of lumbar microdiscectomy using minimally invasive tubular retractor (METRx-MD system, Medtronic Sofamor Danek, Memphis, TN), and to validate the merits of minimally invasive spinal surgery. MATERIALS AND METHODS: From April, 2003 to April 2004 we retrospectively studied a consecutive series of 45 patients who underwent lumbar microdiscectomy using minimally invasive tubular retractor. In all cases, minimally invasive approach using the tubular retractor were performed with a 2 cm sized paramedian incision. The following data were collected: clinical outcomes, operative time, intraoperative blood loss, need for blood replacement, time needed before ambulation, length of hospital stay, and complications. The clinical outcomes were assessed by the modified MacNab criteria. RESULTS: Minimally invasive tubular microdiscectomy was performed in 45 patients over a 12-month period with an average follow-up of approximately 8 months. The clinical outcomes assessed by MacNab criteria were excellent in 33 patients (73%), good in 10 patients (22%). The average operative time was 63 minutes (range, 35 to 95 minutes). The average blood loss was 62 mL (range, 50 to 110 mL). None of the patients needed blood replacement. With the exception of 2 patients, all patients could walk at the day of surgery. The average hospital stay was 2.3 days. None of the patients had dural tear, wound problem, or other complications. CONCLUSION: Lumbar microdiscectomy using tubular retractor can offer a useful modality for the treatment of lumbar herniated disc with the merits of minimally invasive spinal surgery. Further long-term, randomized, prospective investigations are needed to fully evaluate the impact of this technique.

The process of cancer metastasis is dependent on the cancer cells’ capacity to detach from the primary tumor, endure in a suspended state, and establish colonies in other locations.Anchorage dependence, which refers to the cells’ reliance on attachment to the extracellular matrix (ECM), is a critical determinant of cellular shape, dynamics, behavior, and, ultimately, cell fate in nonmalignant and cancer cells. Anchorage-independent growth is a characteristic feature of cells resistant to anoikis, a programmed cell death process triggered by detachment from the ECM. This ability to grow and survive without attachment to a substrate is a crucial stage in the progression of metastasis. The recently discovered phenomenon named “adherent-to-suspension transition (AST)” alters the requirement for anchoring and enhances survival in a suspended state. AST is controlled by four transcription factors (IKAROS family zinc finger 1, nuclear factor erythroid 2, BTG anti-proliferation factor 2, and interferon regulatory factor 8) and can detach cells without undergoing the typical epithelialmesenchymal transition. Notably, AST factors are highly expressed in circulating tumor cells compared to their attached counterparts, indicating their crucial role in the spread of cancer.Crucially, the suppression of AST substantially reduces metastasis while sparing primary tumors. These findings open up possibilities for developing targeted therapies that inhibit metastasis and emphasize the importance of AST, leading to a fundamental change in our comprehension of how cancer spreads.

OBJECTIVE: To evaluate the effects of the reactive oxygen species (ROS) generated with a xanthine(X) and xanthine oxidase (XO) system on sperm function, the change of sperm characteristics, lipid peroxidation, and DNA fragmentation in bovine spermatozoa. MATERIALS AND METHODS: ROS were produced using a combination of 100 micrometer X and 50 mU/ml XO. The ROS scavengers: superoxide dismutase (SOD)(200mu/ml) and catalase (500mu/ml) were also tested. Spermatozoa were incubated for 2 hours in BWW medium with a combination of X-XO supplemented with or without ROS scavengers at 37degrees C under 5% CO2 incubator. Sperm movement characteristics by CASA (computer-aided sperm analysis), HOST (hypoosmotic swelling test), Ca-ionophore induced acrosome reaction, malondialdehyde formation for the analysis of lipid peroxidation, the percentage of DNA fragmentation using the method of TdT-mediated nick end labelling (TUNEL) by flow cytometry were determined after 2 hours incubation. RESULTS: The action of ROS on bovine spermatozoa resulted in a decreased in capacity for sperm motility, Ca-ionophore induced acrosome reaction and membrane integrity, an increased in malondialdehyde formation and the percentage of sperm with DNA fragmentation. In the effects of antioxidant, catalase completely alleviated the toxic effects induced by the ROS in terms of sperm function and characteristics, however SOD exhibited no capacity to reduce the toxic effects. CONCLUSION: The ROS can induce significant damages to sperm functions and characteristics. The useful ROS scavengers can minimized the defects of sperm function and various damages of spermatozoa.

Ulcerative colitis is a chronic relapsing inflammatory disease of the colonic and rectal mucosa, which affects children as well as adults. Inflammation caused by ulcerative colitis is limited to the colon and rectum, to the mucosa and submucosa, and is involved continuously, with varying degrees of ulceration, hemorrhage, edema, and regenerating epithelium. Ulcerative colitis most commonly presents with the onset of diarrhea, later associated with hematochezia, but usually without systemic signs of fever, weight loss, or hypoalbuminemia. Approximately 30% of cases have moderate signs of systemic illness. Although less commonly seen than in Crohn's disease, the first sign of ulcerative colitis may be growth failure characterized by decreased linear growth velocity. We experienced a case of ulcerative colitis with growth disturbance and treated with sulfasalazine. During follow up for a year, the symptoms subsided, and the height and weight increased.

PURPOSE: The prognostic factors in acute lymphoblastic leukemia was patient's age at diagnosis, sex, hepatosplenomegaly, initial WBC & platelet count. Recently immunophenotype has being studied as guidance for several treatment protocol. We performed a retrospective study to evaluate the significance of immunophenotype on clinical course & long-term survival in children with acute lymphoblastic leukemia. METHODS: One hundred two children with acute lymphoblastic leukemia were admitted to the Department of Pediatrics, Yonsei University College of Medicine from Jan.1991 to Dec. 1995, and bone marrow aspiration biopsies and immunophenotyping were performed. The prognostic significance of immunophenotype was evaluated base on the median event free survival and probability of survival at the end of follow-up. RESULTS: 1) In 102 children comprised 14 cases under 2 years old, 71 cases from 2 to 10 years of age and 17 cases above 10 year old. The ratio of male to female was 6 : 4. 2) By CCG risk grouping, standard risk in 21 cases, intermediate risk in 35 cases, high risk in 46 cases. 3) By cytologic classification of FAB, Ll in 65 cases, L2 in 31 cases, L3 in 2 cases 4) Remission induction rate in early pre-B ALL was 100% (39/39), among those recurrence rate 20% (8/39). 5) Remission induction rate in pre-B ALL was 90% (26/29), among those recurrence rate 54% (14/26). 6) Remission induction rate in B-cell ALL was 33%(113), and all cases was expired during follow-up. 7) Remission induction rate in T-cell ALL was 100% (12/12)), among those recurrence rate 41% (5/12). 8) Remission induction rate in T-B mixed ALL was 71%(517), among those recurrence rate 0% (0/5), but non-remission cases was expired during follow-up. 9) Remission induction rate in Myeloid Ag(+) ALL was 83%(516), among those recurrence rate 80% (415). CONCLUSIONS: These results suggest that better result on long-term survival was observed in early pre-B ALL than in T-cell, 7-B mixed, or Myeloid antigen positive ALL and immunophenotype have prognostic impact in acute Iymphoblastic leukemia.
