Ketamine is a safe and effective drug for pediatric anesthesia, sedation and analgesia. We hoped to identify that surgeons could operate a pediatric hernia with the ketamine anesthesia without general anesthesia. The study was a consecutive case series of 2230 inguinal hernia patients aged 1 months to 17 years in a Joo's day-surgical clinic during 11-year period. The patients had pediatric inguinal hernia surgery without general anesthesia under the day-surgery system. We retrospectively analyzed the medical record of patients who were registered with the Diagnosis Related Group (DRG) system. All patients received ketamine (5mg/kg) and atropine (0.01mg/kg) intramuscularly before surgery. After anesthesia, we injected 1~2% lidocaine (Less than 5ml) subcutaneously at the site of incision and started operation. The surgical method was the high ligation method of the hernia sac.) In total 2230 patients, male were 1756 and female were 474. 2076 patients were a unilateral inguinal hernia at the time of surgery and 154 were bilateral hernia patients. Less than three months, depending on the age of the patients was 391, and less than 12 months the patient was 592 people (26.5%). After surgery, there were no accidents or long term complications associated with ketamine anesthesia. We think the surgeon can safely do the pediatric inguinal hernia surgery using ketamine and lidocaine without anesthesiologist through 11 years of our surgical experiences.

OBJECTIVE: Human papillomavirus (HPV) is strongly implicated as a causative agent in the etiology of cervical cancer. Of its gene products, E6 and E7 oncoproteins play major roles by inactivation of cellular p53 and pRb tumor suppressor proteins, respectively. However, it has been recently suggested that p53 and/or pRb-independent functions of E6 and E7 are involved in cervical carcinogenesis. The purpose of this study is to identify novel a cellular target, p73, of E6 and to determine how E6 inactivates p73 function, METHODS: The interaction between E6 and p73 were identified by the yeast two-hybrid assay in vivo and the GST pull-down assay in vitro. The function of the interaction was determined by transient transfections using p21 promoter-CAT reporter plasmid. The molecular mechanism underlying the functional significance of the interaction was further assessed by in vivo and in vitro protein degradation assays, and gel mobility shift assays. RESULTS: Yeast two-hybrid and GST pull-down assays indicate a physical interaction between p73 and either HPV-16 or HPV-11 E6 proteins in vivo and in vitro, respectively. Transactivation domain (amino acid residues 1-49) is found to be absolutely required for this interaction. Transient co-expression of E6 significantly inhibits the p73-mediated activation of p21WAF1 promoter in a p53-defective C33A cell line. Using Ga14-p73 fusion protein, we demonstrate that E6 inhibition of p73 transactivation function is independent of sequence-specific DNA binding, which is confirmed by direct electrophoretic mobility shift assay. Moreover, E6 inhibits p73 function by interfering with the activity of the amino-terminal activation domain. The protein degradation assays in vivo and in vitro indicate that p73, unlike p53, is not susceptible to E6-dependent proteolysis. CONCLUSION: Throughout this study, we identified p73 as a novel cellular target of HPV-E6 protein and found that E6 binds p73 through the amino-terminal transactivation domain, and inhibits its transactivation function independent of the protein degradation and DNA binding. These overall results, consequently, suggest that in addition to the inactivation of p53, the functional interference of p73 by HPV-E6 may, at least in part, contribute to E6-mediated cellular transformation.

p73, a first p53 relative, has been identified at chromosome 1p36, a region that is deleted in variety of human cancers. This protein shares strong homology with p53 protein, suggesting functional similarities with p53. Indeed, p73 can activate p53 downstream genes inducing apoptosis or growth arrest in tumor cells lacking p53. This phenomenon leads us to investigate the function of p73 in ovarian cancer because aberrant p53 was very frequently found in this cancer. We hypothesize that DNA damaging agents trigger p53 dependent apoptotic pathway through p73 instead of p53 in ovarian cancer having aberrant p53. We selected SKOV3 ovarian cancer cell line having no p53 gene and treated this cell line with cisplatin. After the treatment, we examined the transcriptional level of p73 and p21. Moreover, to identify whether the status of p53 influence to the function of p73, we performed same experiment after inserting adenovirus mediated p53(Avp53) into cell line. We detected significantly increased transcripts of p73 whcn treated with cisplatin. But treated with Avp53 or combined treatment with cisplatin, the transcriptional levels were not changed. These data suggest that overexpression of p73 may be important to trigger apoptotic pathway when the p53 gene is lost, but not so important in cells having normal p53.

Intestinal tuberculosis is an infectious disease which is still prevalent in the developing countries including Korea. It may occur insidously, have a vague clinical marofestation, and take a chronic course. We have analyzed 101 cases of intestinal tuberculosis. proven by clinical and histopathologic diagnosis for 10yrs since 1977. The results are as follows: 1) Intestinal tbc was prevalent in the age of 20-30 and the male to female ratio was 1:1.7. 2) Among clinical manifestations, abdominal pain, and tenderness, general malaise and abdominal mass were observed in order of frequency. 3) Active pulmonary lesion was associated in 73 cases (73.3%). 4) Ileocecal region was the most frequent site of involvement in barium study and in colonoscopy. 5) The most frequent colonoscopic finding was multiple ulceration and pseudopolyposis and chronic granulomatous inflammation was noted in 58% on hitopathology. 6) Ulcerative type was the most common type 45.4% by intestinal x-ray and colonofiberscopic examination

OBJECTIVE: Retinoic acids (RAs) and interferons (IFNs) have been implicated in the growth regulation of cervical cancer cells, which was suggested by clinical trials and in vitro experiments. However, the molecular mechanisms of growth regulation are not fully defined, The purpose of this study is to assess the effect of RA and/or IFN on human cervical carcinoma cells in vitro and to analyze their action mechanisms in HPV-positive cervical carcinoma cells by molecular biologic studies. METHODS: HPV-positive (CaSki, HeLa), HPV-negative (C33A, HT-3), and non-cervical cancer Cos-1 cell lines were treated with RA and/ar IFN. Their effects on cell growth were evaluated by the cell pmliferation assay and the following BrdU DNA incorporation assay. The molecular mechanism was further investigated by a series of immunoblottings and transient cotransfection assays, which were conducted in HeLa cells and C33A cells using the CAT reporter gene assay. To observe the down regulation of HPV E6/E7 gene expression by RA/IFN, reverse transcription-polymerase chain reaction (RT-PCR) was perforned. RESULTS: The powth of RA-treated cells was less suppressed than that of IFN-treated cells. Combined treatment of RA and IFN leads to additive effect on the growth suppression of HeLa and CaSki cells. The proliferation activity was most severely reduced in Hela cells by treatment of both all-trans-RA (AtRA) and IFN-r. Combined treatment of AtRA/IFN-r causes a great increase in the level of interferon regulatory factor-1 (IRF-1) protein in HeLa cells, whereas no induction of IRF-1 was observed in C33A cells. The CAT gene expression for IRF-1 was greatly induced by IFN-r in HeLa cells. Immunoblotting assays shows the concurrent induction of p21 CDK inhibitor and dephosphorylation of Rb protein in HeLa cells. In RT-PCR, an individual treatment of either RA or IFN reduced HPV E6/E7 mRNA levels and significantly cooperative when both RA and IFN were treated. By deaeasing E6 levels, the p53 level was increased in HeLs cells treated with RA and/or IFN. Transient cotransfection of IRF-1 and p53 as the transcription factors leads to the cooperative activation of a common p21 promoter to regulate the cell cycle. CONCLUSION: RA/IFN suppressed the growth of HPV-positive cervical cancer cells. When they were both treated, additive suppressive effects were observed in cellular proliferation as well as DNA synthesis. The growth suppressive effect is likely to be related to the increased expression of IRF-1 and p21 (antitumoral effect; p53-independent). The down regulation of HPV E6 gene suppression may account for the resultant increase of p53 levels (antiviral effect; p53-dependent). Both induced IRF-1 and p53 cooperatively augument tbe suppession of p21 CDK inhibitor, which results in dephosphorylation of pRb. Although clinical effects are likely complex and may include interactions of in vitro growth inhibitory effects with immunomodulatory and antiangiogeaetic effect, tbese results suggest the optimal clinical role for the combination of RA/IFN in the treatment of cervical canccers.

Extraperitoneal inguinal endometriosis often presents as an inguinal mass in women of reproductive age, Approximately 40 cases of inguinal endometriosis have been documented in the sutgical and gynecological literature. The overall incidence is in the range of 0.4% of patients with endometriosis. The right side is much more commonly involved than the left (almost 90% of the time in one series of 23 patients), and rarely is the condition bilateral. The most frequent complaint of patients with inguinal endometriosis is an inguinal mass, followed by pain and enlargement of the mass near menstruation. Authors have experienced two cases of endometriosis of the extraperitoneal portion of the round ligament of uterus and report with a brief literature review.
