This study was conducted to evaluate the clinical relevance and effectiveness of ovariectomy (OVE) and ovariohysterectomy (OVH) in terms of postoperative pain behavior and surgical stress. Thirteen healthy intact mongrel purpose-bred female dogs were used in this study. OVE was performed in six dogs whereas OVH was performed in seven dogs. Prior to, 1, 2, 4, 6, 12, and 24 h after surgery, pain assessment was performed by using the Short form of Composite Measure Pain Scale (CMPS-SF) and blood analysis for the determination of glucose, creatine kinase (CK), and cortisol were done. Also, surgical time, duration of anesthesia, and incision length were compared between two groups. As a result, OVH group as opposed to OVE group showed significantly longer in surgical time, duration of anesthesia, and incision length. Also, based on the two-way ANOVA test, the CMPS-SF had significant differences (p < 0.05) between two groups, with the OVE dogs having lower values at 1, 2, 4, and 6 h postoperatively. In addition, in terms of CK, the value at 1, 2, 4, 6, and 12 h were significantly (p < 0.05) increased from the baseline value for the OVH group. However, as for CK in OVE group, the values at 4, 6, and 12 h were significantly increased from the baseline value. As for blood glucose, a significant (p < 0.05) increase from the baseline was shown at 1 h postoperatively in OVH group and no significant increase was shown in OVE group. In terms of serum cortisol level, the values at the 1 and 2 h were significantly (p < 0.05) increased from the baseline value for both groups. In conclusion, our study has shown that OVE can be considered as a superior choice in terms of sterilization technique in female dogs, considering shorter incision length, surgical time, duration of anesthesia along with lower pain and surgical stress response than OVH.

Arterial stiffness(AS) is an important pathologic state of vascular injury. This study was carried out to elucidate the effect of physiological variables on brachial-ankle pulse wave velocity(BAPWV), index of AS. Four hundred adults(volunteers) participated in this study. Body indices, biochemical, cardiac and inflammatory markers, and right(Rt)- and left(Lt)-BAPWV were measured. Body mass index(BMI), Rt- and Lt-BAPWV, glucose, triglyceride, alkaline phosphatase(ALP), gamma-glutamyl transferase(GGT), creatinine, uric acid, troponin-I(TNI), NT-proBNP and high sensitivity C-reactive protein(hs-CRP) levels were higher than the reference value of each variable. Rt- and Lt-BAPWV were directly correlated with age, body weight, BMI, glucose, ketone, aspartate aminotransferase, alanine aminotransferase, ALP, GGT, total cholesterol, low density lipoprotein, lipoprotein(a), apolipoprotein-B, blood urea nitrogen, heart rate, TNI, creatine kinase, CK-MB, lactic dehydrogenase, myoglobin, hs-CRP, lipase, reumatoid factor, fibrinogen and D-dimer (P<0.05, P<0.01, P<0.001 or P<0.000, respectively), but inversely associated with total bilirubin, uric acid, apolipoprotein-A1 and GFR (P<0.05). These observations suggest that a variety of physiological variables may influence BAPWV, resulting in increased risk or prevention of cardiovascular and/or cerebrovascular attacks. Therefore, physiological variables affecting BAPWV should be regularly controlled.

The trophectoderm is one of the earliest cell types to differentiate in the forming placenta. It is an important for the initial implantation and placentation during pregnancy. Trophoblast stem cells (TBSCs) develop from the blastocyst and are maintained by signals emanating from the inner cell mass. However, several limitations including rarity and difficulty in isolation of trophoblast stem cells derived from blastocyst still exist. To establish a model for trophoblast differentiation, we isolated TBSCs from human term placenta ($\geq$38 weeks) and characterized. Cell cycle was analyzed by measuring DNA content by FACS analysis and phenotype of TBSCs was characterized by RT-PCR and FACS analysis. TBSCs have expressed various markers such as self-renewal markers (Nanog, Sox2), three germ layer markers (hNF68, alpha-cardiac actin, hAFP), trophoblast specific markers (CDX-2, CK7, HLA-G), and TERT gene. In FACS analysis, TBSCs isolated from term placenta showed that the majority of cells expressed CD13, CD44, CD90, CD95, CD105, HLA-ABC, cytokeratin 7, and HLA-G. Testing for CD31, CD34, CD45, CD71, vimentin and HLA-DR were negative. TBSCs were shown to decrease the growth rate when cultured in conditioned medium without FGF4/heparin as well as the morphology was changed to a characteristic giant cell with a large cytoplasm and nucleus. In invasion assay, TBSCs isolated from term placenta showed invasion activities in in vivo using nude mice and in vitro Matrigel system. Taken together, these results support that an isolation potential of TBSCs from term placenta as well as a good source for understanding of the infertility mechanism.

Thirty-four strains of Lactobacillus species were isolated from soil and eight of these isolates (M1-4 and P1-4) were capable of growing on red ginseng agar. The M1 and P2 strains were determined to be L. plantarum and other strains (M2, M3, M4, P1, P3 and P4) were determined to be L. brevis. Fermentation of red ginseng extract (RGE) with strains M1, M2, P2 and P4 resulted in a low level of total carbohydrate content (174.3, 170.0, 158.8 and 164.8 mg/mL, respectively). RGE fermented by M3 showed a higher level of uronic acid than the control. The polyphenol levels in RGE fermented by M1, P1 and P2 (964.9, 941.7 and $965.3\;{\mu}g/mL$, respectively) were higher than the control ($936.8\;{\mu}g/mL$). Total saponin contents in fermented RGE (except M1) were higher than the control. RGE fermented by M2 and M3 had the highest levels of total ginsenosides (31.7 and 32.7 mg/mL, respectively). The levels of the ginsenoside Rg3 increased from 2.6 mg/mL (control) to 3.0 mg/mL (M2) or 3.1 mg/mL (M3). RGE fermented by M2 and M3 also had the highest levels of Rg5+Rk1 (7.7 and 8.3 mg/mL, respectively). Metabolite contents of ginsenoside (sum of CK, Rh1, Rg5, Rk1, Rg3 and Rg2) of M2 (13.0 mg/mL) and M3 (13.9 mg/mL) were also at a high level among the fermented RGE. Protopanaxadiol and protopanaxatriol content of ginsenoside of M2 (10.9 and 5.4 mg/mL, respectively) and M3 (11.0 and 5.7 mg/mL, respectively) were at higher levels than other fermented RGE.

There are still debates in the literature on the relative benefits of blood cardioplegia and crystalloid cardioplegia in pediatric cardiac surgery. We performed a clinical trial to compare the myocardial protective effect between HTK solution and blood cardioplegic solution in congenital heart surgery. Material and Method: 15 patients who underwent HTK solution cardioplegia (group 1) and 15 patients who underwent blood cardioplegia(group 2) were included in this study. Preoperative and postoperative serial serum cardiac enzyme levels (troponin I, CK-MB, LDH) were measured in all patients. Clinical data were analyzed and compared between the two groups. Result: There were no differences in age and body weight between the two groups. Operative diagnosis included ventricular septal defect (VSD, n＝4), atrial septal defect (ASD, n＝1), tetralogy of Fallot (TOF, n＝4), and other complex heart diseases (n＝6) in group 1, VSD (n＝7), ASD (n＝5), and TOF (n＝3) in group 2. Cardiopulmonary bypass times were 99.1$\pm$48.1 minutes in group 1, and 69.3$\pm$27.3 minutes in group 2 (p＝0,02). Aortic clamping times were 52.1$\pm$23.6 minutes in group 1, and 37.9$\pm$20.5 minutes in group 2 (p＝0.07). There was no mortality and spontaneous defibrillation was possible in all patients. No differences were observed in the serial enzyme levels between the two groups. There were no differences in the duration of inotropic support and ventilator time between the two groups. Conclusion: HTK solution provided comparable myocardial protection compared with blood cardioplegic solution. A single high dose of HTK solution may be safely and conveniently used for an extended periods as well in congenital heart surgery.

Recently, there has been an increase in the elderly population of the world. Consequently, bone metabolic diseases such as osteoporosis are emerging as a social problem. Osteoclasts play a role in bone resorption, and osteoporosis is induced when bone resorption occurs excessively. Because currently used bone resorption inhibitors may cause side effects when used for a long period of time, it is necessary to develop a new material that effectively inhibits osteoclast differentiation. This study aimed to confirm the inhibitory effect of ethanol extract of Locusta migratoria on RANKL-induced osteoclast differentiation and its mechanism. The toxicity and proliferation effects of LME on RAW264.7 osteoclasts were measured by an MTS assay. There was no cytotoxicity or proliferation when the osteoclasts were treated with up to $2,000{\mu}g/ml$ of LME. In order to confirm the effect of LME on the differentiation of osteoclasts, osteoclasts were treated with RANKL alone or with LME for 3 days. As a result of a TRAP (tartrate-resistant acid phosphatase) assay, the increasing osteoclast differentiation by RANKL decreased in a concentration-dependent manner with the treatment of LME. In addition, LME suppressed the expression of differentiation-related marker genes (TRAP, RANK, NFATc1, and CK) and proteins (NFATc1 and c-Src) that had been increased by RANKL. Also, LME influenced the $NF-{\kappa}B$, ERK and JNK signaling pathways, resulting in the inhibition of osteoclast differentiation. These results suggest that LME may be used as a novel functional material for the prevention and treatment of osteoporosis by playing a role in inhibiting bone absorption.

The purpose of this study was to investigate the growth of lactic acid bacteria and the self-life of Kimchi prepared with Toha sauce(TK) and different kinds of jeot-kal, a traditional fermented fish sauce. The Kimchi samples were stored for 42 days at 12$\pm$2$\^{C}$. The results were as follows: The pH value was decreased in the order of TK, AK(prepared with fermented anchovy juice), SK(prepared with fermented shrimp) and CK(control), and the acidity was increased in the opposed order. Redox potentials decreased until 4 days of fermentation but increased thereafter. TK showed the lowest value in redox potential as well as the lowest change in the number of yeast; however, it had the highest contents of vitamin C and reducing sugar. The total number of lactic acid bacteria was higher in jeot-kal-added Kimchi than control throughout the fermentation period. In sensory evaluation. AK got the highest score in overall preference in the early stage of fermentation, but TK was preferred in the late stage.

Purpose: Trichoblastic fibroma originates from hair germ layer tumor which is a benign tumor mixture of epidermal and mesodermal factor. Trichoblastic fibroma was found only in adults and showed equal occurrence rate between men and women. Since it is a rare tumor, we report a case of a trichoblastic fibroma which developed on the right cheek. Methods: A 72 year-old male was treated with excisional operation 17 years ago due to a solitary tumor that developed on the same site. He returned to the hospital with an asymptomatic mass which have been increasing in size for the last 3 months. Results: In computerized tomography, a size of $2.7{\times}2.3{\times}0.8cm$ tumor was found in the subcutaneous tissue layer. Grossly, the mass was well-circumscribed, smooth-surfaced and flesh colored, and was lobulated and fragile. Pathologic observation showed diverse shaped and sized tumor cell nests and fibrocellular stroma consisting basophilic cells in dermal and subdermal layers. Immunohistopathologic staining showed positive reaction on pancytokeratin, CK-5/6, and bcl-2. Conclusion: By having no connection to the epidermis, and being positioned in the dermal and epidermal layers, typical pathologic findings make it possible to differentiate this tumor with basal cell carcinoma. This lesion is not clear whether it is a local recurrence or not, and it is necessary to observe a new recurrence in the future.

The purpose of this study was to determine the impact of situational, clinical and psychsoical factors on treatment-seeking behavior among those with acute myocardial infarction(AMI). This study used a retrospective, descriptive design. The sample consisted of 72 patients aged over 30 and who were diagnosed with an acute myocardial infarction at two large university-affiliated medical centers from July 1, 1998 to March 30, 2000. But of 72, patients 5 who were an outlier in treatment-seeking time were deleted. Data were collected by using questionnaires, which included demographic data, situational, clinical and psychosocial data. Also patient interviews and chart review were used to obtain information related to treatment-seeking time. The results of this study were summarized as follows ; 1. Mean time from the onset of AMI symptoms to arrival at the hospital was $12.09{\pm}11.44$ hours; 2. Treatment-seeking time was not significantly different by age, gender, or education; 3. Most(44 or 65.78%) patients were at home when they began having AMI symptoms. The remaining patients were either in a public area, workplace or in a car. Patients at home delayed longer than those who had their first symptoms elsewhere, but not significantly different. Also, most patients were with another person when they began to experience AMI symptoms: a spouse(25 or 37.3%), other family member(31 or 46.3%); the remaining 11 were alone. There were no significant differences in treatment-seeking time based on whether alone or with others. Most patients(46 or 68.7%) used an ambulance rather than taking private transportation, and patients who used an ambulance were delayed longer than those who used private transportation, but there were no significant differences; 4. Time to treatment-seeking was not significantly different by blood pressure, heart rate on admission and the peak CK-MB, CPK and Cholesterol level, Killips class; 5. There were no significant statistical differences in treament-seeking times by anxiety level, mood status or control ability.
