OBJECTIVE: To analyse the clinical aspects of vaginal approach for gynecologic pelvic surgery, we evaluated age distribution, parity, indications for hysterectomy, postoperative pathology, operating time, bleeding amount, weight of uterus, postoperative complications. resected uterus weight, operating time and bleeding amount based on operative procedure type. METHODS: We reviewed the medical records of the 136 patients who underwent vaginal approach for gynecologic pelvic surgery for the indications other than uterine prolapse from Jan. 1998 to April. 1998, and from July. 1999 to Sep. 2001 at Chosun University Hospital. RESULTS: We performed 136 cases of vaginal approach for gynecologic pelvic surgery. We performed 132 cases of total vaginal hysterectomy, 4 cases of transvaginal ovarian cystectomy, a high increased rate of vaginal approach for gynecologic pelvic surgery significantly. The most common indication for vaginal approach for gynecologic pelvic surgery was uterine leiomyoma (63.2%), followed by HSIL, adenomyosis, MIC of the cervix, and ovarian cyst. The operating time was within 90 min in almost cases (47.1%). The most common postoperaive pathologic finding was uterine leiomyoma (47.1%), followed by adenomyosis, uterine leiomyoma with adenomyosis, MIC of the cervix, HSIL, LSIL, ovarian serouscys- tadenoma, and endometrioma. There were 4 cases (2.9%) of cuff cellulitis, 2 cases of pelvic cellulitis (1.5%), 3 cases of hematoma formation (2.2%), 1 case of laparatomy (0.7%) as postoperative complications. etc. CONCLUSION: Vaginal approach for hysterectomy and ovarian cystectomy is a safe method for removing uterus even in the absence of prolapse. Recently it's indication is widened to the patient who has larger uterus and history of previous pelvic surgery. Because of it's advantage, Vaginal approach for hysterectomy and ovarian cystectomy would be the preferred method of gynecologic pelvic surgery in the future.

An attenuated classical swine fever virus (CSFV), Suri strain, is a va.iant derived from a vaccine virus, LOM strain. This study was performed to elucidate the molecular biologcal properties of CSFV Suri strain, and to obtain the basic data for molecular epidemiological approaches for the disease. The truncated form of gp55 gene without the C-terminal transmembrane domain, in size of 1,023bp, was amplified by RT-PCR and sequenced by dye terminator cyclic sequencing method, and inserted into BamHI site of pAcGP67B baculovirus vector, establishing a cloned pAcHEG plasmid. By the nucleotide sequences determined, 341 amino acid sequences were predicted. As compared the nucleotide and amino acid sequences of gp55 of Suri with the various CSFV, Suri strain showed the high homology over 99.1% with ALD and LOM strains, but comparably the lower homology with Alfort and Brescia. In comparison of amino acid sequence in variable domain of gp55 protein, the similar tendency of homology was observed. In hydrophobicity analysis, all of four CSFV strains revealed the analogous patterns of hydrophobicity. The numbers and locations of N-glycosylation site and cysteine residues in gp55 were analyzed, those of Suri strain being coincident with ALD and LOM strains. The results suggest that gp55 in Suri strain has the high similarity to those in ALD and LOM strains in terms of the nucleotide and amino acid sequences and the functional properties of gp55 protein..

Fungus ball is commonly found in the paranasal sinus, mostly in the maxillary, followed by sphenoid, ethmoid and frontal sinuses in order of frequency. However, fungus ball in the nasal cavity is extremely rare. In the present case, fungus ball in the nasal cavity was so large that it destroyed the nasal septum and caused nasal septal perforation. We report a rare case of fungus ball in the nasal cavity in a 60-year-old woman, who was successfully treated by nasal endoscopic surgery.

Phosphoinositide-specific phospholipase C(PLC) is known as a key enzyme which produces two major second messengers: diacylglycerol and inositol 1,4,5 trisphosphate. Although it has been suggested that PLC beta isozymes have important roles in nervous system, less is known about the function of PLC beta in development of nervous system. We have localized the mRNA expressions of PLC beta isozymes in the postnatal rat brains by id firm hybridization histochemistry. In the postnatal rat brains, each isozyme of PLC beta showed differential expression pattern. The expression of PLC beta1 mRNA was found in various areas including olfactory bulb, cerebral cortex, caudate putamen, hippocampus, dentate gyrus, and cerebellum. In general, the expression in these areas was gradually increased after birth (PO) until postnatal day 21 (P2l) and slightly decreased to adult level. The expression of PLC beta2 mRNA was not found in postnatal rat brains. The expression of PLC beta3 mRNA was found from P0, peaked at Pl4, and decreased to adult level in the purkinje cells of cerebellum. PLC beta4 mRNA was strongly expressed in the thalamus, cerebellum, cerebral cortex, and olfactory bulb. In these areas, the expression was gradually increased after birth, peaked at P2l, and decreased to adult level. In whole body parasagittal sections of 18 day old rat embryo, PLC betal mRNA was exclusively expressed in nervous tissue, PLC beta3 and PLC beta4 were expressed in various tissues, and the expression of PLC beta2 was not found in any kind of rat tissues. From the different spatiotemporal mRNA expression patterns of PLC beta isozymes in the postnatal rat brains, it is suspected that each PLC beta isozyme may have specific role in signal transduction for postnatal development of rat brain.

Korean Journal of Medical Education 2024;36(3):287-302
Purpose:
Staff is essential to the university’s efficient administrative operations, which are critical for education, research, and service. Medical schools, often independent, need specialized administrative elements. This study explores how medical school staff perceives the organization using the Six-Box model and evaluates their perceived organizational support, job satisfaction, and organizational commitment based on the concept of job attitudes.
Methods:
This study employs a mixed-methods approach, integrating quantitative and qualitative data via a convergent parallel design. It simultaneously collects and analyzes data from a survey and consensus workshop for medical school staff. The survey data were statistically analyzed (IBM SPSS ver. 25.0; IBM Corp., USA), and the workshop discussions were subjected to content analysis. The findings combined provide a comprehensive understanding of the medical school administrative system.
Results:
Quantitative analysis revealed purpose (3.80) as the highest-rated organizational perception and rewards (2.72) as the lowest. Similarly, job satisfaction was highest (3.63) in job attitudes, while perceived organizational support (2.96) was the lowest. Group differences were observed by gender, enrollment capacity, and contract type (p<0.05). In qualitative research, keywords appeared in relation to their experiences within the medical school organization, encompassing doctor training, emotional responses, administrative features, personal attributes, and cultural influences. Overload, faculty issues, and communication gaps are obstacles. Strategies for overcoming these challenges focus on improving staff treatment, resource allocation, training, and communication channels.
Conclusion
This study was conducted to explore a broad understanding of the administration of medical schools. Findings suggest challenges with workload, communication, and organizational support. We propose a dedicated medical school administrative system, improved work conditions, and enhanced communication.
