This is to present 44 cases of hip fractures, of these 28 being fractures of femoral neck and the remainder, intertrochanteric, which were treated at the Department of Orthopedic Surgery, Seoul National University Hospital for four years and 8 months from Jan. 1965 to Aug. 1969. 1. There were 33 males. and 11 females in the series. 26 cases(59.1) were over 51 years of age. 2. The femoral neck fractures were treated by means of Smith Petersen nailing in 16 cases, modified Girdlestone hip arthroplasty in 3 cases, Austin-Moore hip prosthesis in 6 cases and other methods in 3 cases. 3. Modified Girdlestone hip arthroplasty could be a treatment of choice for femoral neck fracture requiring hip arthroplasty for those unsuitable for extensive surgery. 4. The intertrochanteric fractures of femur except for 3 unstable fractures were treated successfully with the Smith-Petersen nail and plate, following anatomical reduction of fracture. In 3 unstable fractures, satisfactory stabilization and internal fixation was obtained by the method of medial displacement of proximal part of distal fragment of fracture.

Reinforced endotracheal tubes (ETTs) are designed to resist kinking or compression. However, these have a potential risk of being obstructed or severed by a patient's bite. We report a case in which a reinforced ETT was severed by tube-bite while the patient was in the prone position during an intensive care unit stay. Bronchoscopic evaluation showed that the severed distal part of the tube had lodged in the patient's right main bronchus, and it had to be surgically removed. The patency of reinforced ETTs should be carefully monitored in patients intubated in the prone position.

7 Korean dogs were anesthetized with oxygen and isoflurane in different concentrations (1 vo1.%, 2 vo1.%, 3 vo1.%). Cardiovascular effects of isoflurane in different concentrations were investigated. The results were as follow: 1) Heart rate was decreased significantly (p<0.05) following increase of isoflurane concentrations. 2) Mean arterial blood pressure was decreased significantly (p<0.05) following increase of isoflur- ane concentrations. 3) Cardiac index was decreased significantly (p<0.05) following increase of isoflurane concentra- tions. 4) Left ventricular stroke work index was decreased significantly (p<0.05) following increase of isoflurane concentrations. 5) Pumonary artery pressure and pumonary artery wedge pressure were decreased significantly (p<0.05) following increase of isoflurane, but there were no significant changes in central venous pressure, systemic vascular resistance and pulmonary vascular resistance.

The phosphorylation and dephosphorylation of proteins on tyrosyl residues are key regulatory mechanisms of cell growth and signal transduction and are controlled by opposing activities of protein tyrosine kinases and phosphotyrosyl phosphatases (PTPs). We have previously cloned and characterized a nontransmembrane chicken protein tyrosine phosphatase 1 (CPTP1) similar to human placental PTP1B (HPTP1B). CPTP1 contains several phosphorylation sequence motifs (S/T-X-X-D/E) for casein kinase II (CKII), [(I > E > V)-Y-(E > G)-(E > D > P > N)-(I/V > L)] for p56(1ck), and (P-E-S-P) for MAP kinase. To examine whether phosphatase activity of CPTP1 could be controlled by phosphorylation, CPTP1 and HPTP1B fusion proteins purified from E. coil were subjected to the in vitro phosphorylation by CKII. Phosphoamino acid analysis revealed that CPTP1 was phosphorylated on both serine and threonine residues by CKII in vitro. In addition, the degree of the phosphorylation of CPTP1 by CKII was shown to be five times higher than that of HPTP1B. Phosphorylation on both serine and threonine residues of CPTP1 in vitro results in an inhibition of its phosphatase activity. This result suggests that phosphorylation of CPTP1 and HPTP1B by CKII might be implicated in the regulation of their catalytic activities in the cell.

OBJECTIVES: Previously, we sought to compile a list of genes expressed during early folliculogenesis by using cDNA microarray to investigate follicular gene expression and changes during primordialprimary follicle transition and development of secondary follicles (Yoon et al., 2005). Among those genes, a group of genes related to the cell size growth was characterized during the ovarian development in the present study. METHODS: We determined ovarian expression pattern of six genes related to the cell size growth (cyr61, emp1, fhl1, socs2, wig1 and wisp1) and extended into CCN family (connective tissue growth factor/cysteine-rich 61/nephroblastoma-overexpressed), ctgf, nov, wisp2, wisp3, including cyr61 and wisp1 genes. Expression of mRNA and protein according to the ovarian developmental stage was evaluated by in situ hybridization, and/or semiquantitative reverse transcriptase polymerase chain reaction (RT-PCR), and immunohistochemistry, respectively. RESULTS: Among 6 genes related to the cell size growth, cyr61 and wisp1 mRNA was detected only in oocytes in the postnatal day5 mouse ovaries. cyr61 mRNA expression was limited to the nucleolus of oocytes, while wisp1 was expressed in the cytoplasm and nucleolus of oocytes, except nucleus. cyr61 mRNA expression, however, was found in granulosa cells from secondary follicles. The rest 4 genes in the cell size growth group were detected in oocytes, granulosa and theca cells. Cyr61 and Wisp1 proteins were expressed in the oocyte cytoplasm from primordial follicle stage. Especially, Cyr61 protein was detected in pre-granulosa cells, Wisp1 protein was not. By using RT-PCR, we evaluated and decided that Cyr61 protein is produced by their own mRNA in pre-granulosa cells that was not detected by in situ hybridization. cyr61 and wisp1 genes are happen to be the CCN family members. The other members of CCN family were also studied, but their expression was detected in oocytes, granulose and theca cells. CONCLUSIONS: We firstly characterized the ovarian expression of genes related to the cell size growth and CCN family according to the early folliculogenesis. Cyr61 protein expression in the pre-granulosa cells is profound in meaning. Further functional analysis for cyr61 in early folliculogenesis is under investigation.

PURPOSE: The treatment of a clinically node-positive (cN+) neck is important in the management of oral cavity squamous cell carcinoma (OSCC). However, the extent of neck dissection (ND) remains controversial. The purpose of our study was to evaluate whether level IV or V can be excluded in therapeutic ND for cN+ OSCC patients. MATERIALS AND METHODS: We performed a retrospective chart review of 92 patients who underwent a comprehensive or selective ND as a therapeutic treatment of cN+ OSCC from January 1993 to February 2009. RESULTS: The incidence rate of metastasis to level IV or V was 22% (16 of 72) on the ipsilateral neck. Of 67 cases without clinically suspicious nodes at level IV or V, 11 cases (16%, 11 of 67) had pathologically proven lymphatic metastasis to level IV or V. Only a nodal staging above N2b was significantly relevant with the higher rate of level IV or V lymph node metastasis (p=0.025). In this series, selective ND, combined with proper adjuvant therapy, achieved regional control and survival rates comparable to comprehensive ND in patients under the N stage of cN2a OSCC. CONCLUSION: In conclusion, level IV and V patients can avoid recurrence under cN2a OSCC.

OBJECTIVE: The implantation failure after embryo-transfer (ET) is a major continuing problem in in vitro fertilization (IVF). This study was undertaken to determine the effectiveness of intravenous immunoglobulin for treatment of individuals experiencing repeated unexplained in vitro fertilization-embryo transfer (IVF-ET) failure. METHODS: A total of nine consecutive infertile patients who failed to become pregnant after previous IVF-ET replacing at least three or more normal developed embryos each were included in our study. During the subsequent new IVF-ET cycle, each women received intravenous immunoglobulin 500mg/kg before the embryo transfer. RESULTS: Only one implantation occurred. There were no remarkable side effects. A specific effect of intravenous immunoglobulin for patients with repeated IVF-ET failure could not be demonstrated. CONCLUSION: High-dose intravenous immunoglobulin may not be useful for patients with repeated failure of embryo transfer.
