2.The Affinity of Calmodulin-Affigel for Inositol Triphosphate Kinase From Bovine Brain.
Yeungnam University Journal of Medicine 1990;7(1):39-50
The one event on signaling mechanism is the cleavage by adenyl cyclase of ATP into second messenger, cyclic AMP. The other transfer system of inositol metabolism, it is widely recognized that hydrolysis of the minor membrane lipid phosphoinositide bisphosphate (PIP₂) initiated by occupation of certain receptors and catalyzed by phospholipase C, lead to toe generation of the two intracellular messengers, inositol triphosphate (IP₃) and diacylglycerol (DG). IP₃ is converted to inositol tetrakisphosphate (IP₄) by IP₃ kinase. In the present study, it is that purification of calmodulin is used by phenyl-Sepharose CL-4B chromatography, it's molecular weigh, 17,000 in SDS-polyacrylamide gel electrophoresis. In order to observe the affinity between calmodulin (CaM)-Affigel 15 and IP₃ kinase, and isolated IP₃ kinase, was applied in CaM-Affigel with Ca²⁺ equilibrium buffer and EGTA equilibrium buffer. We compared with binding and elution effect of IP₃ kinase in several condition of buffer. In affinity of binding, Ca²⁺ equilibrium buffer was in the most proper condition, and elution, CaM/Ca²⁺buffer (CE 1 10.36, CE2 12.76pM/min/mg of protein) was effected much more than EGTA buffer (E2 1.48, E 2.43pM/min/mg of protein), but CaM/Ca²⁺stimulate the activity of IP₃ kinase. And then, several detergents such as sodium deoxycholate, tween 20, cholic acid, polyethylene glycol, chaps were applied. The 0.2% chaps buffer (E2 23.19, E3 8.05pnM/min/mg of protein) was the most effective in elution of IP3 kinase.

4.Predictors of health-related quality of life in Koreans with cardiovascular disease
Osong Public Health and Research Perspectives 2022;13(1):62-70
This study aimed to identify the predictors of health-related quality of life (HRQoL) in Korean adults with cardiovascular disease (CVD). Methods: This was a cross-sectional study with a stratified multistage probability sampling design. Data from the 2016 to 2019 Korea National Health and Nutrition Examination Survey (n=32,379) were used. Among the participants aged 19 years or older (n=25,995), 1,081 patients with CVD were extracted after excluding those with missing data and those who had cancer. The participants’ HRQoL was measured using the three-level EuroQoL Group’s five-dimension questionnaire (EQ-5D) scale. Data were analyzed using the t-test, one-way analysis of variance, and general linear regression for complex samples. Results: The most potent predictors of HRQoL in Korean adults with CVD were limited activity (β =−0.103, p <0.001), poor perceived health (β =−0.089, p <0.001), depression (β =−0.065, p<0.01), low household income (β=−0.033, p<0.05), unemployment (β=−0.023, p<0.05), and older age (β=−0.002, p<0.01), which explained 37.2% of the variance. Conclusion: Comprehensive interventions that address both physical and mental factors and social systems that provide financial help need to be implemented to improve the HRQoL of Korean adults with CVD.

PURPOSE: Muscle mass, strength, and composition determine muscle quantity and quality. However, data on muscle properties in relation to bone mass or insulin resistance are limited in Asian populations. This study aimed to investigate the relative importance of muscle measurements in regards to their relationship with lower bone mass and insulin resistance. MATERIALS AND METHODS: In this study, 192 postmenopausal women (age, 72.39±6.07 years) were enrolled. We measured muscle cross-sectional area (CSA) and attenuation at the gluteus maximus and quadriceps muscles through quantitative computed tomography. Muscle strength and physical performance were evaluated with the hand grip test and Short Physical Performance Battery (SPPB). Pearson correlation analysis and linear regression were performed to evaluate the relationship between muscle properties and homeostatic model assessment-insulin resistance (HOMA-IR) or bone mineral density (BMD). RESULTS: Muscle CSA, hand grip strength, and SPPB score held positive correlations with spine and hip BMDs, but not with insulin resistance. In contrast, muscle attenuation of the gluteus maximus or quadriceps was inversely related to HOMA-IR (r=−0.194, p=0.018 and r=−0.292, p<0.001, respectively), but not BMD. Compared with the control group, muscle CSA was significantly decreased in patients with osteoporosis; however, decreased muscle attenuation, indicating high fat infiltration, was found only in patients with diabetes. CONCLUSION: Muscle mass, strength, and physical performance were associated with low bone mass, and accumulation of intramuscular fat, a histological hallmark of persistently damaged muscles, may play a major role in the development of insulin resistance in Korean postmenopausal women.

Both idiopathic pulmonary fibrosis (IPF) and pulmonary involvement of collagen vascular disease(CVD) are well known cause of diffuse interstitial lung disease which lead to fibrosis and honeycombing. We analyzed HRCT findings of 33 patients with IPF and 14 patients with CVD in terms of predominant pattern, site of involvement, mediastinal lymph node enlargement, pleural change and pulmonary volume loss. Criteria of mediastinal lymph node enlargement and pleural thickening were 15mm in long diameter and 3mm, respectively. Volume loss of the lung was measured by using hilar height ratio (apex to hilum/hilum to diaphragmatic dome). Mean age was 61 years for IPF and 46 years for CVD and male: female ratio was 27:6, 4:10, respectively. Predominant HRCT pattern was honeycombing for IPF (63%), and ground-glass opacity for CVD (66%) (p=0.001). Predominantly, subpleural involvement was seen in 90% for IPF and 74% for CVD. Mediastinal lymph node enlargement was seen in 47% of the patient with IPF and 14% with CVD (p=0.004). pleural thickening was seen in 97% of the patients with IPF and 42% with CVD (P=0.002), Pleural effusion was seen in 10% of the patients with IPF and 36% with CVD (P=0.009). Hilar height ratio of more than 1.5 was seen in 84% of the patients with IPF and 29% with CVD. In conclusion, our study shows that patients with IPF are prone to have more progressed stage of pulmonary fibrosis than the patients with CVD on HRCT.
