Anthropometric Analysis of Mid-face; Senile Changes of Nasal Dimensions

The objective of this study is anthropometric analysis of nose and mid-face in Korean. This study was based on extensive sample size and variable measurement points. Total 3,000 healthy volunteers (18 to 79 years of age) were took two standardized photographs (frontal and lateral view). And 21 items were measured per person. Age groups were classified into three as young, middle-aged, and elderly. Average nasal length was around 4 cm and height was 5 cm. Female was 5~6% smaller than male. Facial width was 3.5 times larger than nasal length. Nasal length reduced by 5% as get older. Nasofrontal angle was 141degrees and nasolabial angle was 92degrees. Nasal width was 39mm and intercanthal distance was 35 mm. The significant age-related changes were eyeball depth (se-pu) and intercanthal distance. The characteristic senile change of male mid-face was downward deflection of soft tissue but female was soft tissue atrophy. The goal of augmentation rhinoplasty is not filling up sellion point depression but superior shifting of that point. Similarity between nasal length and width was another interesting finding of Korean nose. The results of this study will represent typical values of Korean nose and facilitate exact prediction of surgical results.

Fluoxetine Up-Regulates Bcl-xL Expression in Rat C6 Glioma Cells

OBJECTIVE: To analyze both differentially expressed genes and the Bcl-xL protein expression after acute and chronic treatment with fluoxetine in rat C6 glioma cells. METHODS: C6 glioma cells were cultured for 24 h or 72 h after treatment with 10 microM fluoxetine, and gene expression patterns were observed using microarray and qRT-PCR. Then, cells were cultured for 6 h, 24 h, 72 h or 96 h after treatment with 10 microM fluoxetine, and the expression of Bcl-xL protein was measured using western blot. RESULTS: As determined by microarray, treatment with fluoxetine for 24 h up-regulated 33 genes (including Bcl-xL and NCAM140) and down-regulated 7 genes (including cyclin G-associated kinase). Treatment with fluoxetine for 72 h up-regulated 53 genes (including Gsalpha and Bcl-xL) and down-regulated 77 genes (including Galphai2 and annexin V). Based on the qRT-PCR results, there was an increase in Gsalpha mRNA and a decrease in Galphai2 mRNA at 72 h in fluoxetine-treated cells as compared to control, a result that was consistent with microarray. We also observed an increase in Bcl-xL mRNA (both at 24 h and at 72 h) in fluoxetine-treated cells as compared to control, demonstrating a tendency to increase gradually. Bcl-xL protein expression increased as the duration of fluoxetine treatment increased. CONCLUSION: These results suggest that chronic treatment with fluoxetine not only initiates the cAMP pathway through inducing Gsalpha expression but also induces Bcl-xL expression, thus inhibiting apoptosis.

Small bowel obstruction in early pregnancy: A case report / 대한산부인과학회지

Intestinal obstruction occurs rarely as a cause of acute abdominal pain during pregnancy. It is very difficult to make diagnosis, as nausea, vomiting and abdominal pain are commonly associated with pregnancy, and X-rays are avoided if possible. However, delayed diagnosis can cause intestinal strangulation, which results in a high incidence of maternal morbidity, mortality, premature labor, and fetal loss. The incidence of intestinal obstruction seems to increase at the time of rapid uterine size changes such as between 16~20 weeks, 32~36 weeks or even in the puerperium. The possibility of intestinal obstruction must always be kept in mind when a pregnant woman with an operation scar on her abdomen develops abdominal pain. We present a case of small bowel obstruction during early pregnancy with a brief review of the literature who had the history of right salpingo-oophorectomy and appendectomy operation

Proteomic Analysis of Penile Protein Alterations in a Rat Model of Cavernous Nerve Injury

PURPOSE: Cavernous nerve resection (CNR) in rats is a standard model of animal experiments on erectile dysfunction (ED) that occurs after radical prostatectomy (RP). Injured cavernous nerves after surgery can cause fibrosis and apoptosis that lead to penile structural changes that may be accompanied by alterations of protein expression. This study aimed to analyze the changes in protein after CNR in Wistar Kyoto rats. MATERIALS AND METHODS: Using 8-week-old male Wistar Kyoto rats, sham and CNR operation under a microscope were performed. Two and 8 weeks after surgery, we applied 2-DE and MALDI-TOF/TOF (AB 4700) to identify differently expressed penile proteins after CNR. 2-DE gels were stained with silver nitrate and were analyzed with PDQuest. After in-gel digestion, peptide mass spectra were obtained by MALDI-TOF/TOF mass spectrometry in the positive ion reflector mode. The obtained data were screened with a rat database from both the NCBI and the Swiss-Prot/TrFMBL home page. RESULTS: The proteins that were changed more than 1.5-fold compared with the sham group were annexin A4 and pyruvate kinase (PK). Annexin A4 was increased by 1.75-fold after 2 weeks, whereas PK was decreased by 4.16 after 8 weeks. These results were confirmed by immunohistochemistry. CONCLUSIONS: Annexin A4 in the CNR group was increased, which may be related to emiocytosis during apoptosis. The decrease in PK of the CNR group is assumed to be related to a decrease in efficacy during glycolysis. Further study will be needed to elucidate the molecular pathophysiology of ED after cavernous nerve injury.

A Case of Pelvic and Abdominal Actinomycosis Associated with Wearing an Intrauterine Device / 대한산부인과학회잡지

Actinomycosis, a rare disease entity in the upper genital tract, and caused by anaerobic bacteria, Actinomyces israelii, presents some difficulties in establishing a correct preoperative diagnosis. Pelvic actinomycosis has been reported more frequently in women with intrauterine device (IUD). Actinomycosis may be confused with malignancy and other inflammatory diseases due to its infiltrative nature and tendency to invade normal anatomic barriers. So, cervicovaginal smear is recommended for all women wearing IUDs, and actinomyosis should be suspected in such patients suffering pelvic infections. We experienced a case of pelvic and abdominal actionomycosis complicated by tuboovarian abscess in a 52 year-old woman wearing IUD and report it with a brief review of related literatures.
