3.Isolation of GTP binding from bovine brain.
Yeungnam University Journal of Medicine 1993;10(2):360-368
GTP binding protein (G-protein) associated with membrane and involved in signal transduction was isolated from bovine brain, and molecular weight of G protein was observed. As the results, cell membranes were homogenized from bovine brain tissues and proteins of membrane were gained using 1% cholate, and progressed the chromatography. The purification process was performed by step, DEAE-Sephacel, Ulttrogel AcA 34 and heptylamine-Sepharose column chromatography. The chromatographic fractions were confirmed by GTP binding assay and SDS-polyacrylamide gel electrophoresis. Molecular weight of Goa was revealed 39,000 dalton and GR 36,000 dalton. One more step of heptylamine-Sepharose was enforced to purify the GTP binding protein. Finally I gained the GTP binding protein isolated subtype of Goalpha and Gbeta.

OBJECTIVE: Because endometriosis is difficult to diagnose and has a high recurrence rate after treatment, a reliable serum marker of endometriosis is necessary. Therefore, the aim of this study is to measure the serum levels of CA125 and CA19-9 in patients with endometriosis before and after treatment and during recurrence, and to assess the usefulness of these levels in the diagnosis, clinical follow up and prediction of recurrence in endometriosis. METHODS: Eighty-eight patients who visited the department of Obstetrics and Gynecology of Ewha Mokdong Hospital from January 1994 to December 1998 and were diagnosed as endometriosis by laparoscopy or explo-laparotomy were enrolled as subjects. A retrospective analysis of serum CA125 and CA19-9 levels at 1 month before and 3 to 6 months after initiation of treatment was done. RESULTS: The serum CA125 and CA19-9 levels of endometriosis group(81.0+/-252.5, 36.6+/-53.4 ; mean+/-2SD, U/ml) before treatment was significantly higher than control group(11.6+/-12.8, 9.4+/-8.6)(p<0.05). Overall sensitivity rate for CA125, CA19-9 levels and both was 53.4%, 42.9% and 64.3% respectively. The sensitivity rate for endometriosis, stage 3 and 4(85.4%, 55.0%) was significantly higher than that, stage 1 and 2(p<0.05). The serum CA125 level in endometriosis group showed a significant increment according to stages(p<0.05) while the serum CA19-9 level showed an increasing trend(p=0.055) and both levels decreased significantly after treatment(p<0.05). The serum CA125 level was also higher at recurrence after treatment(p<0.05). CONCLUSIONS: The serum CA125 and CA19-9 levels are a useful marker for diagnosing severity of disease, monitoring efficacy of treatment and predicting recurrence in endometriosis.

PURPOSE: This paper studies the influence of the case-management program on the change of blood sugar, lifestyle, and knowledge level of diabetes mellitus (DM) for medium-sizedenterprise employees suffering from DM. METHOD: Subjects, divided into experimental and control groups, are 59 workers with FBS higher than 126mg/dl or under DM medication treatment in the medium-sized enterprises, being managed by two distinct university hospital group occupational health management service teams. The case management program for DM patients consists of 6 different processes in which each subject is treated. RESULT: FBS decreased in the experimental group after the program, while that of the control group increased significantly. In the experimental group, the amount of smoking, the frequency of drinking and the amount of drinking per week decreased. Also, the knowledge level for DM and the change of nutrition management showed significant increase. In the control group, the amount of smoking increased and the frequency of drinking, the amount of drinking and nutrition level did not change significantly. And the knowledge level for DM decreased. CONCLUSION: We expect that taking this case management program for DM management may significantly improve diabetic patients' overall health.

PURPOSE: The purposes of this study are to discribe the high-resolution computed tomographic (HRCT) findings of pulmonary histiocytosis X and to evaluate the relationship between the extent of the lesion on HRCT and pulmonary function test (PFT). MATERIALS AND METHODS: We retrospectively analyzed the HRCT findings of 8 patients with pathologically proved pulmonary histiocytosis X. The morphological pattern and incidence of the lesions were evaluated. The extent of the lesions were correlated with the results of PFT by calculating Spearman correlation. RESULTS: The most common HRCT findings were thick-walled cysts (n=8) followed by nodules (n=7). Other associated findings were reticulation, ground-glass opacification, and conglomerate nodules. The extent of the disease on HRCT was correlated inversely with percent predicted value of functional vital capacity. CONCLUSION: Common HRCT findings of pulmonary histiocytosis X were cysts with irregular wall thickening and nodules. The extent of the disease on HRCT correlated with the severity of restrictive pattern of PFT.

9.Epidemiology and pathogenesis of scabies
Journal of the Korean Medical Association 2023;66(12):701-704
Scabies infestation is known to be more common in hot and humid climates, areas with low medical accessibility, and households with many family members living together. Recently, the number of collective residence facilities for chronic patients and elderly people has increased in developed countries. Furthermore, mass infections are occurring in these facilities.Current Concepts: The cause of scabies infestation is Sarcoptes scabiei var. hominis. It takes about 9 to 15 days for an egg to hatch and grow into an adult mite. Adult mites have an oval body and four pairs of legs. Female mites lay eggs and live for 4 to 6 weeks. In order to spread, mites from an existing host must transfer to a new host. Therefore, external environments such as temperature and humidity are advantageous for the survival of mites, and the closer the distance to other hosts, the higher the infestation rates. In general, scabies infestation induces T helper (Th) 1 cell-mediated reaction, which can prevent the proliferation of mites to some extent. However, in crusted scabies infestations, Th2 cell-mediated response is mainly induced. This response does not suppress the proliferation of the mites and makes them more contagious.Discussion and Conclusion: It is necessary to keep in mind and accurately know the characteristics of scabies when diagnosing skin diseases. The Korean Society of Dermatology has selected eradication of the scabies infestation as a key project and is actively providing support to group residential facilities such as nursing hospitals.
10.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.
