Background: In non-small cell lung cancer (NSCLC) patients with preoperative high serum carcinoembryonic antigen (CEA) level, patients with a persistently high serum CEA level after surgery have been reported to have a poor prognosis. In addition, in other cancers, the post/preoperative serum CEA ratio has been reported as a useful parameter. Materials and Methods: We enrolled 123 NSCLC patients with preoperative high CEA levels (${\geq}5ng/mL$) who underwent curative surgery between 2004 and 2011. Prognostic significance of postoperative serum CEA level and the CEA ratio was examined. Results: The 5-year survival of patients with persistently high serum CEA level after surgery was poor. On the other hand, patients with normal postoperative serum CEA levels had significant favorable prognosis. The patients with CEA ratio>1 had poor prognosis, however the number was only 7 (5.7%). The 5-year survival rates of patients with other subgroup based on the CEA ratio ($0.5{\geq}CEA$ ratio and $0.5{\leq}CEA$ $ratio{\leq}1$) was similar. Multivariate analysis revealed prognostic significance for the postoperative serum CEA level but not the CEA ratio. Conclusions: For NSCLC patients with preoperative high serum CEA level, their postoperative serum CEA levels is a more significant prognostic factor than the post/preoperative serum CEA ratio.

This study was carried to identify whether acupuncture at several meridian points can affect the human anesthesia or not through the analysis of serum intermediates, such as, melatonin, serotonin, TSH, cortisol in human serum. We investigated the effect of accupuncture on the change of serum intermediates which have frequently been made a subject of discussion owing to its hyponic and sedative properties in practice. The result obtained were as follow ; 1. Serum melatonin levels was hardly affected at 40 minutes after general acupuncture on Hab-Gog, Nae-Gwan, and the other meridian points as compared with that($5.64{\pm}1.02pg/ml$) of resting control group. But on day 1 after acupuncture, these tend to increase significantly ($7.95{\pm}2.05pg/ml$ to $8.21{\pm}1.57pg/ml$, p <0.05). On the other hand, control group under sleep showed the serum level of $7.39{\pm}1.03pg/ml$. Additional acupuncture at In-Dang induced the increased melatonin level, especially at 40minutes after acupuncture(p <0.05). 2. Serotonin level in resting control serum recorded $51.14{\pm}8.17{\mu}g/ml$. Acupuncture at determined meridian point intend to increase average level of serotonin, but not significant. However observation on day 1 after acupuncture at Hab-Gwan meridian point and under sleeping showed the significantly increased serotonin level, $74.05{\pm}35.83{\mu}g/ml$, $70.44{\pm}13.08{\mu}g/ml$, respectively. 3. TSH level in intact human serum recorded $0.85{\pm}0.24{\mu}IU/ml$. and the serum exposed to acupuncture showed the irregular pattern of TSH level in a mean range of $0.76{\pm}0.44{\mu}IU/ml$ to $1.06{\pm}0.38{\mu}IU/ml$, regardless of meridian point or time after acupuncture. 4. The values of serum cortisol in control group were $11.76{\pm}2.06{\mu}g/dl$ in resting, $7.51{\pm}2.85{\mu}/dl$ under sleep, respectively. The level of serum cortisol in 40minutes after acupuncture was markedly (p <0.05) reduced to the serum levels of $5.65{\pm}2.58{\mu}g/dl$ (Hab-Gog, Nae-Gwan), $7.58{\pm}3.21{\mu}g/dl$ (Gyo-Gam, Sin-Mun besides Hab-Gog, Nae-Gwan), $6.43{\pm}3.54{\mu}g/dl$ (In-Dang besides to Hab-Gog, Nae-Gwan), respectively, as compared with control, intending to increase a little on day 1 after acupuncture. From the above results, the analysis of serum intermediates suggest that acupunctuation at meridian points applied to at this study act upon the phase of light anaesthesia or hypnosis, at the same time affect pituitary-adrenal axis rather than hypothalamus-pituitary axis in the secretary system of hormone and also don't affect dorsal-raphe nucleus according to the observation of change transition in serum intermediates, such as TSH, serotonin, and cortisol.

Growth, mammary development, serum concentrations of growth hormone, prolactin and estradiol which affect the growth and mammary development, were investigated in Korean Native heifers and Holstein heifers from 5 months old to 15 months old. From 5 months old to 15 months old, body weights in Korean Native heifers averaged 37%, lower than those in Holstein heifers of the same age (P<.01). Teat volumes in Korean Native heifers are average 67% smaller than those in Holstein heifers. Analysis of serum protein by secondary electrophoresis showed differences in protein pattern between the breeds and between the individuals. From 5 months old to 15 months old, serum concentration of growth hormone in Korean Native heifers was averge 47% lower than that in Holstein (P<.01), yet prolactin concentrations in serum were about the same between the two breeds. However serum concentration of estradiol in Korean Native heifers was average 20% higher than that in Holstein of same age (P<.01). This result showed evidently that the decrease of the growth hormone concentration in serum, while growing up, causes to retard the growth and mammary development in Korean Native heifers compared to Holstein heifers.

This study was to investigate 1) the correlation of serum Ca, with depression and anxiety ; and 2) the effect of Ca intake on those symptoms. The subjects were three females and two males who were 53-66 years old with the severe subjective symptoms of depression and anxiety. They have taken more than twice Ca of RDA(recommended dietary allowances for Koreans) daily for 6 months(dietary treatment). The prestudy Ca intake of the subjects was low: 60% of RDA for Koreans. Their serum Ca concentration was also low: 6.67 $\pm$ 0.15mg/d1 before the dietary treatment. They expressed severs depression and anxiety, with high self scores in a psychological test. Their serum Ca concentration increased to 8.32 $\pm$ 0.17mg/dl after six months of dietary treatment, while the symptoms of depression and anxiety decreased significantly after two months and nearly disappeared after six months. This result seemed to be an effect of the dietary high Ca intake. Serum Ca and the psychological states of depression and anxiety correlated negatively, and the coefficients of determination were high in the results of linear regression analysis of depression and anxiety by serum Ca. Therefore the serum Ca concentration could be a good marker to predict depression or anxiety relatively well. The continuous high Ca intake could decrease the probability of developing depression or anxiety and mitigate their symptoms because serum Ca concentration increased, while the state of depression and anxiety decreased with the increased Ca intake.

In this study, the serum level of 25-hydroxyvitamin D(25-(OH)D) was measured by high pressure liquid chromatography(HPLC), and factors affecting it were investigated in 72 young adults age ranging from 21 years to 39 years with normal bone density. The mean level of serum 25-(OH)D was 20.0$\pm$6.8ng/ml in males and 26.1$\pm$12.3ng/ml in females, which was significantly higher in females (p<0.01). The serum level of parathyroid hormone(PTH) showed a negative correlation with that of 25-(OH)D(p<0.05). Time spent outdoors in a day correlated positively with the serum level of 25-(OH)D(p<0.01). During the day, a specific time between 12:00 a.m. and 2:00 p.m. showed the most significant correlation with the level of 25-(OH)D(p<0.005). Among the nutrients studied, fat and vitamin D intake were positively correlated with the serum 25-(OH)D level. Stepwise multiple regression analysis showed that the serum level of 25-(OH)D could be fit by vitamin D intake(34.7% explained), serum PTH level (27.3% explained) and the time spent outdoors during the specific time(28.4% explained).1996)

A serum-pulp method was applied to concentrate peach pulp with aroma recovery. The serum portion was concentrated to five-fold at $50{\sim}55^{\circ}C$ and $30{\sim}50$ mmHg with aroma recovery. The concentrated serum, insoluble pulp and aroma fraction were recombined to make a two-fold concentrated peach pulp. The results of GC and GC/MS analysis for volatile compounds and sensory evaluation of concentrated peach pulp indicated that flavor quality was significantly improved by addition of aroma fractions. A 10% aroma recovery appeared to be appropriate for peach pulp.

Objective: The aim of the present study was to investigate the relationship between ovarian follicle count and volume on ultrasonography and serum hormone levels including the levels of the anti-$M\ddot{u}llerian$ hormone (AMH) and gonadotropin in women with the polycystic ovary syndrome (PCOS). Methods: A total of 118 Korean women aged 18-35 years who were newly diagnosed with PCOS at a university hospital were included in this study. Serum LH, FSH, and AMH levels were measured in the early follicular phase, and the total antral follicle count (TFC) and the total ovarian volume (TOV) were assessed by ultrasonography. The correlations between serum hormonal parameters and ultrasonography characteristics in women with PCOS were evaluated using Pearson's correlation coefficients and a linear regression analysis. Results: Serum AMH levels were significantly correlated with serum LH levels and LH/FSH ratios, and TFC and TOV were significantly correlated with each other on ultrasonography. Serum AMH and LH levels and the LH/FSH ratio were significantly correlated with TFC. Statistically significant correlations between TOV and the LH level (r=0.208, p=0.024) and the LH/FSH ratio (r=0.237, p=0.010) were observed. However, the serum AMH level was not significantly correlated with the ovarian volume, and this result did not change after adjusting for age and body mass index. Conclusion: Serum AMH is not related to the ovarian volume in women with PCOS. My results suggest that serum LH level and the LH/FSH ratio may be more useful than the serum AMH level for representing the status of the ovarian volume in women with PCOS.

Background: Breast cancer is the most common malignancy with the highest incidence rates among women worldwide. Triple-negative breast cancer (TNBC) disease is diagnosed more frequently in younger women, and is associated with a poor prognosis. Elevated levels of serum haptoglobin protein (Hp) are observed in many malignant diseases including breast cancer. We evaluated the expression and prognostic value of Hp among patients with TNBC. Materials and Methods: Serum Hp levels were determined by Elisa in 41 patients with TNBC and 10 normal individuals. Hp status was correlated with other clinico-pathological parameters including patient survival. Results: Of the 41 patients with TNBC, Hp over expression was detected in 24 (59%) by Elisa. Hp up-regulation was confirmed by Elisa based quantification in the serum of 41 TNBC patients against lower grades and 10 normal individuals. Survival analysis revealed that Hp ($p=2.016{\times}10^{-5}$), stage ($p=2.166{\times}10^{-5}$), distant metastasis ($p=2.217{\times}10^{-5}$), tumor size ($p=1.053{\times}10^{-5}$), and tumor grade (p=0.001), correlated with patient survival on univariate analysis. Multivariate analysis revealed that Hp (p=0.001), and grade of the disease (p=0.008) were independent predictors of survival. Conclusion: Our results indicate that serum levels of Hp may play a role as a potential serum biomarker and prognostic indicator among TNBC patients. Thus, Hp may present a new promising prognostic biomarker in TNBC patients, but independent validations are now necessary for confirmation.

This study was undertaken to determine the correlation between β-amyloid, serum lipid levels, and cognitive function in the elderly with mild Alzheimer's dementia. The study was conducted in December 2018, enrolling 45 elderly people with mild Alzheimer's disease. Blood analysis measured the β-amyloid and serum lipid levels, and cognitive function was measured using MMSE-K. The correlation between β-amyloid, serum lipid levels and cognitive function was determined using Pearson's correlation analysis. A significantly negative correlation was observed between the β-amyloid level and cognitive function (p<0.05). Furthermore, serum lipid levels and cognitive function also revealed a significantly negative correlation between TC and LDL levels (p<0.05). These results indicate that increasing levels of β-amyloid, TC, and LDL augments a negative correlation that decreases the cognitive function, signifying that management of pathologic factors related to dementia is important for the prevention and improvement of cognitive function in dementia patients.
