Pentastarch is a new synthetic hydroxyethyl starch similar to hetastarch. We report on the clinical comparisons the clinical efficacy and safety of 10% pentastarch in prime solutions for CPB in cardiac operations with that of 20% serum albumin. During CPB, group P [n = 20] received 500ml of 10% pentastarch and group A [n = 20] received 100ml of 20% albumin in prime solutions The postoperative time of ICU stay in group P and the day and amount of chest drain, hospital stay in group A were longer [p<0.05]. Fresh whole blood and PRBC were added only in group A and a higher amount of hartman solution was added in group A during CPB [p<0.05]. Prothrombin time was prolonged preoperatively and 2 days postoperatively in group A and 7 days postoperatively in group P [p<0.05] but there were no significant differences in bleeding time or fibrinogen level. Platelet count was higher immediately postoperatively in group A and preoperatively and 1, 2, and 7 days postoperatively in group P [p<0.05].Total protein and albumin level were higher 1 day postoperatively in group A and 2 and 7 days postoperatively in group P [p<0.05]. BUN was increased 2 days postoperatively in group A and Cr was increased 1 day postoperatively in group P [p<0.05]. CPK was higher preoperatively and 1, 2, and 7 days postoperatively in group A and plasma hemoglobin level was also higher 2 and 7 days postoperatively in group A [p<0.05]. There were no significant differences in arterial blood gas analysis but higher pO2 and lower pCO2 levels were maintained in group P and ejection fraction was higher 7 days postoperatively in group P [p<0.05]. Both groups were improved postoperatively in NYHA class and the hemodynamic parameters such as MAP, CO, CI, SV, LVSWI were well maintained in group P [p<0.05]. The amount of blood products used was higher in group A and urine output was higher immediately postoperatively in group A and 1, 2 days postoperatively in group P and the chest output was higher in group A. The complications were developed in 7 patients in group A and 5 patients in group P and mortality was not present in both groups.In conclusion, 10% pentastarch is as safe and effective as 20% albumin in prime solutions for cardiopulmonary bypass in cardiac operations.
Objectives: This study was aimed to analyze the correlation of clinical characteristics of cancer patients treated with Korean Medicine and their natural killer cell activity (NKA). Methods: The medical records of 52 cancer patients who conducted NKA test at Cheonan Korean Medicine Hospital of Daejeon University from March 2016 to May 2018 were reviewed. NKA was determined at Seegene Medical institute using NK Vue Gold(R) kit, evaluating activated $IFN-{\gamma}$ by enzyme immunoassay after incubation of whole blood. Careful investigations were conducted by categorizing the patients by their sex, origin, stage, ECOG scale, and conventional treatment type. We used data from the medical records and statistical analysis using SPSS 25.0 V. Results: The average NKA of all patients was $623.1{\pm}722.0pg/mL$. The NKA value was higher for females than for males. No correlation was evident between age and NKA, but patients aged over 70 years had the lowest NKA average result. Stage III and IV patients showed clearly lower NKA values when compared to stage I and II patients. NKA and ECOG scale values showed no evident relationship. Conclusions: This study presented the characteristics of NKA in cancer patients treated with Korean medicine. The NKA result differed by gender and stage. Based on these findings, further study is needed regarding the clinical meaning of NKA.
Background and Purpose Although sleep disturbances are common and considered a major burden for patients with Alzheimer's disease (AD), the fundamental mechanisms underlying the development and maintenance of sleep disturbance in AD patients have yet to be elucidated. The aim of this study was to examine the correlation between regional cerebral blood flow (rCBF) and sleep disturbance in AD patients using technetium-99m hexamethylpropylene amine oxime single-photon emission computed tomography (SPECT). Methods A total of 140 AD patients were included in this cross-sectional study. Seventy patients were assigned to the AD with sleep loss (SL) group and the rest were assigned to the AD without SL group. SL was measured using the sleep subscale of the Neuropsychiatric Inventory. A whole-brain voxel-wise analysis of brain SPECT data was conducted to compare the rCBF between the two groups. Results The two groups did not differ in demographic characteristics, severity of dementia, general cognitive function, and neuropsychiatric symptoms, with the exception of sleep disturbances. The SPECT imaging analysis displayed decreased perfusion in the bilateral inferior frontal gyrus, bilateral temporal pole, and right precentral gyrus in the AD patients with SL group compared with the AD patients without SL group. It also revealed increased perfusion in the right precuneus, right occipital pole, and left middle occipital gyrus in the AD with SL group compared with the AD without SL group. Conclusions The AD patients who experienced sleep disturbance had notably decreased perfusion in the frontal and temporal lobes and increased rCBF in the parietal and occipital regions. The findings of this study suggest that functional alterations in these brain areas may be the underlying neural correlates of sleep disturbance in AD patients.

The concept of biostimulation of wounds by low-level laser therapy(LLLT) is attracting considerable attention. Although its effect on whole tissues has been studied quite extensively, the biological and cellular mechanisms underlying LLLT have not been clarified. In an experimental radius fracture in rabbits, Tang and Chai reported that LLLT enhanced the activity of red blood cells, macrophages, fibroblasts, chondrocytes, and osteoclasts within the fracture area. The purpose of the present study was to evaluate the effect of LLLT with a GaAlAs diode laser device on bone healing in rabbit mandibular fractures. We use 12 rabbits for this study. All rabbits were fractured mandible angle area using saw in anesthetic condition. In control group(n=6), none treatment was performed at fracture site. In experimental group(n=6), LLLT with a GaAlAs diode laser was radiated at fracture site daily for 7 days. All rabbits were sacrificed at 6 weeks later from performed fracture day. We studied the immunohistochemical staining of CD34 and Vimentin and the histochemical analysis for calcium and phosphorus content. The results were as follows. 1. In the histological and immunohistological staining, after 6week, fibroblasts, osteogenic cells and collgen fibers were observed more in experimental group than in control group. 2. In the histochemical analysis, the amount of calcium and phosphorus contents of the experimental group were more than the control group. From the results obtained, we suggest that the bone healing is stimulated by low-level laser irradiation in bone fractures.
Cerebral ischemia results from a transient or permanent reduction in cerebral blood flow that decreases oxygen and glucose supply. When the cellular oxygen supply is reduced to critical level, damage to cells and induction of cell death are occurred by excitotoxicity, oxidative stress and inflammation. Ischemia remains one of the leading causes of death, but there is no effective treatment that might protect neurons gainst ischemia by interrupting the cascade of cell death. In this study, human neuroblastoma SH-SY5Y cells are exposed to oxygen and glucose deprivation (OGD) followed by reoxgenation. OGD can mimic the acute restriction of metabolite and oxygen supply caused by ischemia and is widely used as a model of ischemic conditions. SH-SY5Y cells are treated samples at the commencement of OGD to achieve different final concentrations, and cell viabilities were quantified using the measurement of flow cytometry analysis. Of those tested, the extracts of Polygala tenuifolia (roots), Dictamnus dasycarpus (barks), Polygala tenuifolia (roots), Eucommia ulmoides (branches), Eucommia ulmoides (barks), Poria cocos (whole), Sophora flavescens (roots) showed neuroprotective effects, with $EC_{50}$ values of $4.5{\pm}0.6$, $7.9{\pm}1.5$, $10.5{\pm}0.7$, $18.4{\pm}1.9$, $19.6{\pm}0.3$, $21.6{\pm}1.9$, and $30.7{\pm}3.9{\mu}g/m{\ell}$, respectively.
Secondary prevention via earlier detection would afford the greatest chance for a cure in premalignant lesions. We investigated the exomic profiles of non-malignant and malignant changes in head and neck squamous cell carcinoma (HNSCC) and the genomic blueprint of human papillomavirus (HPV)-driven carcinogenesis in oropharyngeal squamous cell carcinoma (OPSCC). Whole-exome (WES) and whole-genome (WGS) sequencing were performed on peripheral blood and adjacent non-tumor and tumor specimens obtained from eight Korean HNSCC patients from 2013 to 2015. Next-generation sequencing yielded an average coverage of $94.3{\times}$ for WES and $35.3{\times}$ for WGS. In comparative genomic analysis of non-tumor and tumor tissue pairs, we were unable to identify common cancer-associated early mutations and copy number alterations (CNA) except in one pair. Interestingly, in this case, we observed that non-tumor tonsillar crypts adjacent to HPV-positive OPSCC appeared normal under a microscope; however, this tissue also showed weak p16 expression. WGS revealed the infection and integration of high-risk type HPV16 in this tissue as well as in the matched tumor. Furthermore, WES identified shared and tumor-specific genomic alterations for this pair. Clonal analysis enabled us to infer the process by which this transitional crypt epithelium (TrCE) evolved into a tumor; this evolution was accompanied by the subsequent accumulation of genomic alterations, including an ERBB3 mutation and large-scale CNAs, such as 3q27-qter amplification and 9p deletion. We suggest that HPV16-driven OPSCC carcinogenesis is a stepwise evolutionary process that is consistent with a multistep carcinogenesis model. Our results highlight the carcinogenic changes driven by HPV16 infection and provide a basis for the secondary prevention of OPSCC.
The purpose of this study is to show that, before registration of chronic degenerative diseases and enforcing management system in health centers, the management of hypertension could achieved comprehensively and continuously by knowing the realities of drug-taking and its related factors those who are being cared for in health centers. For one year, a questionnaire about drug-taking realities of hypertensive patient was distributed at 8 health centers in Taegu from March 24. 1997 to April 24. 1997. The questionnaires were then collected and analysed. The results are as follows: Of 691 patients, 77.4% of patient were taking medicine regularly every day. The reasons why patients weren't taking medicine every day was as follows: the blood pressure became normal(34%, the highest of the group), patients forgot(28.2%), it was difficult to buy the medicine(15.4%), there was no effect even though the patient took medicine continuously. The experience of medical treatment outside of health centers was 28.9%. The types and percentages of alternative medicine are herbs (50.5%), health food(24.5%), folk remedy(13.7%). Among them, 44.6% of patients didn't know if the medicine was effective. Medical treatment places excluding health centers was pharmacies(63.5%-the highest rate). In simple analysis, the older one was the more regularly one took the medicine, but there was no statistical relations. Of health activities, patients eating low-salt diet showed that they took the medicine regularly. Nonsmoking patients and those who experienced drug side-effect and those who doubted doctor's prescriptions and instructions showed that they took alternative, excluding modem medicine. Anti-hypertensive drug medication status according to recognition, attitude, experiences of hypertension showed that patients who thought that they should take anti-hypertensive drug during the whole life time took the medicine regularly(82.3%). The reasons for patients turning to alternatives varied. In case of having subjective symptom(34.1%), those who thought they knew the hypertension well(36.6%), they decided to use alternatives. In multiple logistic regression analysis the key statistics were as follows: The older patients, patients who ate low-salt diet, patients who thought that they should take anti-hypertensive drug during the whole life time, all showed that they took medicines regularly. And also patients who experienced drug side-effect, doubted prescriptions and instructions, and patients who had subjective symptoms, patients who thought that he knew the hypertension very well, all showed higher rate of using alternative medicine. In the future, at the health centers, to register and manage hypertension patients effectively, we must educate patients about regular drug-taking, and alternatives without doctor's prescriptions.
This aimed at figuring out if there were the radioprotection effects of aronia on livers of laboratory rats radiated through serum test. For the objects of animal testing, one group consists of five male laboratory rats (weight 200~250 g), and the groups were set as follows: Group 1, normal; Group 2, 5 Gy radiated control group; and Group 3, 5 Gy radiated experiment group with aronia. Group 1(A) was prescribed with ordinary meal without radiation while the control group, Group 2(B) was prescribed with ordinary meal and radiation, and the experiment group, Group 3(C) was orally prescribed with aronia (daily oral dosage: 100 mg/kg/day) diluted with distilled water at the amount of 50 mg/kg/day twice a week, using oral zonde needle for rats for 14 days before being radiated, and then, radiation were made on them. For the study, using Linac (Linear Accelerator) 6 MV X-ray therapy device, rats were irradiated on their whole bodies once, and their blood was sampled for conducting five blood serum tests with regard to liver. For statistical analysis, ANOVA test was conducted. In conclusion, as a result of the analysis, it seemed that there were no the radioprotection effects of aronia on liver. However, it was confirmed statistically that ALB (P>0.05) showed no significance and that TP (P<0.05) showed significant differences. It is expected that there should be more tests in future.

Purpose : Rett syndrome(RTT) is an X-linked dominant neurodevelopmental disorder affecting 1 per 10,000-15,000 female births worldwide. It was initially described by Andreas Rett in 1966. RTT involves developmental regression characterized stereotypic hand movements, tremors, gait apraxia, seizures, deceleration of head growth after the age of 6-18 months. The disease-causing gene was identified as MECP2 on chromosome Xq28. We carried out mutational analysis of MECP2 genes in RTT patients. Methods : Whole blood(5 cc) of 34 sporadic RTT patients was collected in EDTA-anticoagulated tubes. Genomic DNA was extracted from peripheral blood using the E.Z.N.A. blood DNA kit. Four exons of the MECP2 gene were amplified by PCR in 34 Korean with RTT. We carried out PCR divided the exon three into two parts and the exon four into five parts. Primer sequences designed by Amir et al. in 1999 were almost used(AF030876). Sequencing primers used were the same as PCR. DNA sequencing reactions were performed using an ABI 377 DNA sequencer and ABI PRISM dye terminator cycle sequencing reaction kit(Perkin-elmer). The results were compared with the normal DNA sequence(X99686). To confirm the change of sequence on novel mutations, RFLP analysis was performed. Results : The MECP2 mutations were detected in 23(67.6%) of the 34 patients. The mutations consisted of 12 different types including nine missense and three nonsense mutations. Of these, three (L100V, G161E and T311M) mutations were newly identified. Most of the mutations discovered are located within MBD(39.1%) and TRD(39.1%). In this study, three(T158M, R270X, R306C) mutations were identified high frequency. Conclusion : MECP2 gene was also an important cause of Korean RTT patients. MECP2 gene study is an important tool for diagnosis of Korean RTT patients.
It is to be growing up the interest of community health affairs through visiting nursing care. The health medical treatment of Korea has been changed largely on the period. The juvenile population has decreased. This means that is has took the population consensus of advanced national organization to be increased by the old age. The transition of disease has changed from the contagious disease importance to the chronicity disease omportance because the domestic district population has experienced the sudden urbanization circumstance district population has experienced the sudden urbanization circumstance to be growing up $70\%$ of the whole population. When the nursing service has common function to be delivering from all direction to home, this study is getting the great important phase velocity in order to manage the kernel questional adult chronicity disease of health medical institution at the present age. (1) community over system or with people particularity (2) the first of third step medical treatments. The variety of medical treatments organization has quantity of the delivery manpower and specially between consumers and rdlated person. A qualitative difference is showed at the purpose to be seizing. That research related person is use at district health center in Seoul, by foundation on nurse registration book of H collage hospital and public health registration book. According the chronicity disease. age. and sex. nature agree-able standard 54 people took the content analysis on nurse registration book of total 108 people. The results of the study were as follows: 1. General background factors are houses or kind of medical facilities and number of patients in family. The first medical treatment is more patients than third medical treatment organization. The first medical treatment of economic environment os appering to be worse. 2. The chronicity disease frequency have been different speciality according to medical treatment organization. On case of the first medical treatment. Diabetes and High Blood Pressure were good but Cerebrum Vascular Accident(CVA) showed many for bed case. In addition. the number of family is comparative large exception of CVA on according for moving condition and health more than the first medical treatment. However. family condition. whole family percentage is decreasing preferably through the potential resource is increasing by the number of and the construction of family. The ability of real resource is considered to be low. 3. The average percentage of nurse service has appered to be differed two groups by the first step medical treatment(33.72 times) and third step medical treatment(45.70 times). However, the difference (the first step medical treatment and third step medical treatment) is to be limited to issue the medicine at the service. The condition of nurse care was the indirect nursing care. Supportiong area was to be related to volunteer service and administration support. 4. The various nursing care average percentage of the chronicity disease was increased by orders of Diabetes. High Blood Pressure. and CVA in examination result and the medical treatment. The indirect nursing care was also same. At third step medical treatment, orders of chronicity disease were same. The case of other area on service conditions were increased by order of Diabetes. High Blood Pressure, and CVA. However. it is never appearing the difference at bottleneck affairs nursing care. 5. When the visiting nursing care demand particularly. the average percentage of nursing care from the first step medical treatment that the time under a person is many more than the time over two people. However, there was no difference in statistic. Third step medical treatment is $49.81\%$ at the time under a person. The average nursing care service is appeared by more many when the visiting nursing care demand is a few by 12.83 at the time over two people. 6. By visiting nursing care percentage to be frequency that nursing care averaghe percentage and inter-relation are large. The related factor of the first medical treatment is 0.96. However, the related factor of third medical treatment has shown the decreased 0.49 for the condition of relation more than that. Therefore. the nursing care average percentage is related to the visiting times of a nurse. This result is be showing the obvious fact that the first step medical treatment is few more than third step medical treatment.
