Objective This study aimed to develop a nomogram that predicts ongoing pregnancy after in vitro fertilization and embryo transfer (IVF-ET) using patient age and serum hormonal markers. Methods A total of 284 IVF-ET cycles were retrospectively analyzed. At 14 days post-oocyte pick-up (OPU), the serum human chorionic gonadotropin (HCG) and progesterone levels were measured. The main predicted outcome was ongoing pregnancy. Results Patient age and serum of HCG and progesterone levels at 14 days post-OPU were good predictors of ongoing pregnancy. The cut-off value and area under the curve (AUC) (95% confidence interval) were 36.5 years and 0.666 (0.599-0.733), respectively, for patient age; 67.8 mIU/mL and 0.969 (0.951-0.987), respectively, for serum HCG level; and 29.8 ng/mL and 0.883 (0.840-0.925), respectively, for serum progesterone level. When the prediction model was constructed using these three parameters, the addition of serum progesterone level to the prediction model did not increase its overall predictability. Furthermore, a high linear co-relationship was found between serum HCG and progesterone levels. Therefore, we developed a new nomogram using patient age and HCG serum level only. The AUC of the newly developed nomogram for predicting ongoing pregnancy after IVF-ET cycles using patient age and serum HCG level was as high as 0.975. Conclusion We showed that ongoing pregnancy may be predicted using only patient age and HCG serum level. Our nomogram could help clinicians and patients predict ongoing pregnancy after IVF-ET if the serum JCG level was ${\geq}5IU/L$ at 14 days post-OPU.

Objectives: In recent studies, increased AMH level has been suggested as objective surrogate marker for diagnosis PCOS, one of the major causes of oligomenorrhea. The purpose of this study is to report the clinical effect of Korean medicine treatment on oligomenorrhea patient with increased Anti-mullerian hormone level, who can be diagnosed who can be ruled out PCOS. Methods: A 27 year old woman with oligomenorrhea was enrolled in this study. We measured serum hormone levels and ruled out PCOS. The patient received Korean medicine treatment for 3 months, we assessed the result of treatment through observation of the menstrual cycle and follow-up measurements of serum hormone levels. Results: 1. The patient had menstrual cycle regularly. 2. Increased serum AMH level of the patient decreased from 12.16 ng/ml to 8.51 ng/ml. 3. The other serum hormone levels such as testosterone, LH/FSH ratio decreased Conclusion: This case shows that Korean medicine treatment could have a beneficial effect on menstrual cycle and decrease the increased serum hormone levels of ruled out PCOS patient.

Objective: Growth hormone and its mediator, insulin-like growth factor-1 (IGF-1), have been suggested to exert gonadotropic actions in both humans and animals. The present study was conducted to assess the relationship between serum IGF-1 concentration, seminal plasma concentration, and sperm parameter abnormalities. Methods: A total of 79 men were enrolled in this study from December 2011 to July 2012 and were prospectively analyzed. Patient parameters analyzed included age, body mass index, smoking status, urological history, and fertility history. Patients were divided into four groups based on their semen parameters: normal (A, n=31), abnormal sperm motility (B, n=12), abnormal sperm morphology (C, n=20), and two or more abnormal parameters (D, n=16). Patient seminal plasma and serum IGF-1 concentrations were determined. Results: Patient baseline characteristics were not significantly different between any of the groups. The serum IGF-1 levels in groups B, C, and D were significantly lower than the levels in group A; however, the seminal plasma IGF-1 levels were not significantly different between any of the groups. Conclusion: Men with abnormal sperm parameters had significantly lower levels of serum IGF-1 compared with men with normal sperm parameters. Seminal plasma IGF-1 levels, however, did not differ significantly between the groups investigated here. Further investigations will be required to determine the exact mechanisms by which growth hormone and IGF-1 affect sperm quality.

Background: Oral squamous cell carcinoma (OSCC) constitutes a group of tumors that exhibit heterogeneous biology, histopathology, and clinical behaviors. Case presentation: A 73-year-old male had a whitish leukoplakia-like lesion around inflamed peri-implant area (#42, #43, and #44), and this lesion had transformed to OSCC within 3 years. He underwent mass resection, selective neck dissection, and reconstructive surgery. To detect any carcinogenesis progression, we examined the removed tumor tissue as well as the patient's preoperative and postoperative sera to identify causative oncogenic proteins using immunoprecipitation high-performance liquid chromatography (IP-HPLC). Conclusions: The protein expression levels of p53, E-cadherin, β-catenin, MMP-10, HER2, NRAS, Met, HER2, and ERb were significantly lower in the serum collected on postoperative day 10 than in the preoperative serum, and if these proteins are consistently not elevated in the serum 3 months after surgery compared with the preoperative serum, these proteins can be potential oncogenic proteins. However, we also found that the serum extracted 3 months after the operation had elevated levels of oncogenic proteins compared with that of the preoperative and 10-day postoperative serum indicating the possibility of tumor recurrence. At postoperative follow-up period, ipsilateral neck metastasis and second primary lesion were found and additional surgery was performed to the patient. IP-HPLC using the patient's serum shows the possibility of oncogenic protein detection. However, follow-up IP-HPLC data is needed to find out patient-specific prognostic factors.

Biphenyl Dimethyl dicarboxylate(DDB) has been regarded as a safe, effective drug for decreasing serum aminotransferase levels from elevated serum aminotransferase levels, which cause acute or chronic hepatitis and chronic liver diseases. This study was designed to low dose(22.5mg/day) & short-term therapy effectiveness for 4 weeks of DDB in 30 chronic hepatitis patients with elevated serum aminotransferases. The following results were observed. 1. Serum alanine aminotransferase(ALT) levels significantly decresed from 173. $97\pm130.62(U/L)$ of pretreatment level to $32.23\pm19.22(U/L)$ after treatment for 4 weeks(p<0.00l) and normalized patients by $73\%$ 2. Serum aspartate (AST) aminotransferase levels significantly decreased from $94.90\pm49.17(U/L)$ of pretreatment level to $45.30\pm23.25(U/L)4 after treatment(p0<0.01). 3. However, no significant effects in the serum AST & ALT changes by which cause hepatitis and hepatitis duration (p>0.05). 4. No significant adverse effects were observed except for mild epigastric discomfort in one patient during DDB treatment It is suggested that DDB small dosage administration can result effectively decreasing serum aminotransferase levels from chronic hepatitis patients with elevated serum aminotransferase levels.

This study was conducted of investigate the antioxidant vitamins and serum lipids status of 23 healthy female subjects and 22 female patients suffering from cerebrovascular disease hospitalized at any of three of general hospitals in Taegu. The systolic blood pressure of patients suffering from cerebrovascular disease(151.4$\pm$30.2mmHg) was significantly higher than healthy controls(129.7$\pm$17.8mmHg). The frequency of drinking alcohol and smoking in patients was also higher. Analysis of patient and control dietary intakes revealed that all subjects were consuming the minimed recommended energy-nutrient levels. HDL-cholesterol(26.15 vs 37.74mg/dl), serum vitamin E(12.69 vs 17.74mg/l) and vitamin C(65.59 vs 152.50ug/dl) levels were significantly lower, but triglyceride(221.01 vs 87.30 mg/dl) and total-cholesterol / HDL-cholesterol levels(5.98 vs 4.89)were significantly higher in the patient group. According to the results of this study, it is expercted that refraining from smoking and drinking alcohol, cultivating healthy living habits which can decrease stress, and maintaining suitable levels of serum antioxidant vitamins can prevent the occurrence of cerebrovascular disease.

Serum lipid peroxide levels in 25 chronic renal failure patients undergoing hemodialysis were examined by determining TBA reaction with spectrofluorometry. The lipid peroxide levels, 208.9$\pm$88.4nmol/ml, in the patient group was significantly higher than 152.4$\pm$43.9nmol/ml of 48 control healthy subjects. It is likely that the elevated serum lipid peroxide levels can play a role in increasing tendency of hemorrhage and incidence of atherosclerosis in chronic renal failure patients.

Purpose: The aims of this study was to compare and evaluate the clinical characteristics, laboratory data, and prognosis for infants under age 1 year with CMV hepatitis and those with viral hepatitis of unknown etiology. Methods: A retrospective study was conducted of infants under age 1 year who were admitted with acute hepatitis. The exclusion criteria consisted of: autoimmune, genetic, metabolic, toxic, HAV, HBV, HCV, toxoplasma, rubella, herpes simplex, and Epstein-Barr virus. The 30 patients included were divided into two groups based on markers for CMV (IgM anti-CMV, CMV PCR in urine, CMV culture in urine). Results: The median age of patients (n=15) was 2.8 months. No other organ involvement was detected in any patient. Peak serum total bilirubin levels (n=4) ranged from 2.6 to 6.7 mg/dL. Peak serum ALT levels ranged from 51 to 1,581 IU/L. The duration of ALT elevation ranged from 1.5 weeks to 26 weeks (median 9 weeks). All had recovered in full without ganciclovir; there were no cases of hearing loss. The median age of controls (n=15) was 2.5 months. Peak serum total bilirubin levels (n=4) ranged from 1.6 to 9.1 mg/dL. Peak serum ALT levels ranged from 26 to 1,794 IU/L. No significant differences were observed between both groups regarding the peak serum ALT levels, peak serum total bilirubin levels, duration of hyperbilirubinemia and ALT elevation. Conclusion: Although it was not possible to differentiate congenital infection with perinatal infection in this study, the prognosis of patients with CMV hepatitis without other organ involvement was good without ganciclovir treatment.

To evaluate the significance of assay of serum thyroglobulin(Tg) in monitoring the course of the thyroid cancer or its response to treatment, serum thyroglobulin levels were measured in 41 patients with thyroid cancer who visited Seoul National University Hospital from August, 1981 to August, 1982. The results were as follows: 1) Serum Tg levels $1\sim3$ months after thyroidectomy was $31{\pm}23$ ng/ml$(mean{\pm}S.D.)$ in 14 patients without metastasis, $66{\pm}41$ ng/ml in 21 patients with regional metastasis and $176{\pm}59$ ng/ml in 6 patients with distant metastasis and there were significant differences among three groups(p<0.01). 2) Serum Tg levels in 13 patients with metastasis before and after $^{131}I$ treatment were $134{\pm}62ng/ml$ and $67{\pm}52ng/ml$ respectively. 3) In the follow-up measurement of serum Tg levels every 3 months for about 1 year, almost all serum Tg levels were below 60 ng/ml in 12 patients without distant metastasis and serum Tg levels were elevated above 60 ng/ml in 5 of 6 patients with distant metastasis. 4) In 6 patients with distant metastasis, serum Tg levels were elevated in 5 patients and $^{131}I$ whole body scan showed definite metastatic evidence in 3 patients and suspicious evidence in 1 patient. From above results, we concluded that serum Tg level is very useful as an indicator of recurrence or metastasis in patients with thyroid cancer after operation.

Inhaled inorganic dusts such as coal can cause inflammation and fibrosis in the lung called pneumoconiosis. Chronic inflammatory process in the lung is associated with various cytokines and reactive oxygen species (ROS) formation. Expression of some cytokines mediates inflammation and leads to tissue damage or fibrosis. The aim of the present study was to compare the levels of blood cytokines interleukin (IL)-$1\beta$, IL-6, IL-8, tumor necrosis factor (TNF)-$\alpha$ and monocyte chemoatlractant protein (MCP)-1 among 124 subjects (control 38 and pneumoconiosis patient 86) with category of chest x-ray according to International Labor Organization (ILO) classification. The levels of serum IL-8 (p= 0.003), TNF-$\alpha$ (p=0.026), and MCP-1 (p=0.010) of pneumoconiosis patients were higher than those of subjects with the control. The level of serum IL-8 in the severe group with the small opacity (ILO category II or III) was higher than that of the control (p=0.035). There was significant correlation between the profusion of radiological findings with small opacity and serum levels of IL-$1\beta$(rho=0.218, p<0.05), IL-8 (rho=0.224, p<0.05), TNF-$\alpha$ (rho=0.306, p<0.01), and MCP-1 (rho=0.213, p<0.01). The serum levels of IL-6 and IL-8, however, did not show significant difference between pneumoconiosis patients and the control. There was no significant correlation between serum levels of measured cytokines and other associated variables such as lung function, age, BMI, and exposure period of dusts. Future studies will be required to investigate the cytokine profile that is present in pneumoconiosis patient using lung specific specimens such as bronchoalveolar lavage fluid (BALF), exhaled breath condensate, and lung tissue.
