1.Purpose Stroke is the most frequent cause of mortality and morbidity rate in Korea with ischemic heart disease and cancer. Recent recurrence rate of stroke is high, but little attention had been given to the features of its' cause. The purpose of this studies is to examine the hematologic states in Korean normal adults through premature-examination of stroke(PES). 2.Method The study group consisted of 326 cases that they had no significant results by CT through premature examination of stroke(PES) in Cheonan oriental hospital of Daejeon university. We tested RBC, hemoglobin, hematocrit, WBC, PT, PTT, PLT, total protein, albumin, total bilirubin, direct bilirubin, GOT, GPT, $\gamma$-GTP, total cholesterol, triglyceride, HDL-C, glucose, BUN, creatinine, Na, K and evaluated by cross sectional study. 3.Result In the PES, there were many patients with low RBC(11%), shorten PT(26.7%), delayed PTT(19.3%), high TP, GPT, ${\gamma}$ -GTP(respective1y 16.9%, 14.4%, 13.5%), high cholesterol level and triglyceride level(respectively 18.7%, 28.2%). We didn't found significant cases in hemoglobin, hematocrit, WBC, PLT, albumin, total bilirubin, direct bilirubin, GOT, HDL-C, glucose, BUN, creatinine, Na, K. 4.Conclusion In this study, we demonstrated that short PT, high triglyceride level are special views in PES. Also prospective studies are needed continuously to search the preventing methods of the CVA.

This study was conducted by surveying 616 male workers living in Ulsan City regarding their health status based on lifestyles such as alcohol consumption, smoking and exercising as well as physical measurements and biochemical tests. The average height, weight and BMI(body mass index, $kg/m^2$) of the subjects was 170.9cm, 70.2kg and 24.2, respectively. The rate of drinking was $80.9\%$ and the rate of smoking was $53.4\%$. Seventy four percent of subjects responded that they exercise regularly. The results of the blood biochemical tests revealed that the average hemoglobin concentration was 14.7g/dl, and the levels of GPT(glutamic pyruvic transaminase) and GOT (glutamic oxaloacetic transaminase) were 32.74unit/l, 26.99 unit/l, respectively. The average hemoglobin concentration for the subjects aged in the 50s was 14.39g/dl, which was significantly lower than those in the 20s(14.81g/dl), 30s(14.69g/dl) and 40s(14.73g/dl). The blood glucose level and the cholesterol level also increased with age. Also investigated was the blood pressure of the subjects increased with age,. and there was a significant increase(p < 0.05) for the subjects in the 50s compared to those in the 20s. The frequency of alcoholic beverages was significantly correlated with systolic/ diastolic blood pressure(p < 0.05) and $\gamma-GTP(gamma\;glutamyl\; transpeptidase)$(p<0.01). The duration of smoking showed a negative correlation(p < 0.05) with the hemoglobin and positive correlations with diastolic blood pressure, cholesterol and $\gamma-GTP(p<0.01)$. The study shows that blood pressure, blood glucose level, cholesterol level, GOT, GPT and $\gamma­GTP$ level, increase with age, which indicates higher possibility of degenerative diseases, calling for nutritional education in terms of advisable lifestyles regarding eating habits, alcohol consumption, smoking and regular exercise.

Objective: This study was conducted to investigate the effect of Chaenomelis Fructus (CF) water extract on thioacetamide (TAA)-treated rats. Methods: Rats were divided into five groups: one normal group (n=8) and four with TAA-induced hepatic injury. These treatment groups were administered distilled water (n=8); silymarin 100 mg/kg (n=8); CF 100 mg/kg (n=8); and CF 200 mg/kg (n=8). In the TAA groups, the acute liver injury was induced via IP injection (200 mg/kg), and the silymarin and CF extract were then orally administered for three days. Subsequently, serum levels of GOT, GPT, and ammonia were confirmed as well as protein expressions using liver tissue. Results: In the liver injury-induced rats, CF administration reduced tissue damage and serum levels of GOT, GPT, and ammonia. In addition, CF increased the anti-oxidant proteins Nrf2, Keap1, HO-1, and catalase and significantly regulated matrix metalloproteinases (MMP-2 and MMP-9) and their tissue inhibitors (TIMP-1 and TIMP-2). Conclusions: In this animal model of liver injury induced by TAA, CF extract is determined to have a hepatoprotective effect by increasing anti-oxidant proteins that relieve damage and by regulating the expression of matrix metalloproteinases.

Objectives : This study was undertaken to investigate the hepatoprotective effect of Spatholobi Caulis water extract (SC) to thioacetamide (TAA)-induced acute liver injury (ALI) in rats. Methods : The rats were injected intraperitoneally with TAA (200 mg/kg body weight) and orally administered SC (100 or 200 mg/kg b.w.) daily for 3 days. Liver biomarkers were assessed by serum glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and ammonia levels. Malondialdehyde (MDA) was measured both serum and liver tissue. In addition, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, anti-oxidant, and inflammation-related proteins were investigated by western blot analysis. Histological examination further confirmed though hematoxylin and eosin stain. Results : The SC treatment reduced liver function markers like GOT and GPT and also remarkably decreased ammonia level. Moreover, the elevated MDA level in TAA-induced group was significantly reduced by SC treatment. NADPH oxidase expression associated with oxidative stress including NOX2, NOX4, and p47phox markedly inhibited by SC administration. SC treatment exerted anti-oxidant effect through the increase of anti-oxidant enzyme including superoxide dismutase (SOD), Catalase, and heme oxygenase-1 (HO-1). The protein expressions of inflammatory cytokines such as tumor necrosis factor-�� (TNF-��), IL-6, and IL-1�� induced by nuclear factor-kappa B (NF-��B) activation were modulated through blocking the phosphorylation of inhibitor of nuclear factor ��B�� (I��B)��. SC treatment also improved histological alterations. Conclusion : These findings suggested that SC administration may be a potential candidate for the prevention or treatment of ALI.

The purpose of this study is to investigate the effects of the herbal Chokong pill (hereafter HCKP) on the liver cell and enzyme activities of serum in rat. HCKP were mixed with pickled black soybeans and five different kinds of medicinal herbs (Rhynchosia nulubilis, Glycyrrhiza uralensis, Zizyphus vulgaris, Atractylodes macrocephala K., Astragalus membranaceus and Cornus officinalis). Four groups of male Sprague-Dawley rats were fed by different diets for 9 weeks: normal diet (Nor), high-fat diet (HF), high-fat diet supplemented with 1% (T1) and 5% (T5) HCKP powder, respectively. Depending on the presence of HCKP in high fat diet, the activities of the blood serum GOT and GPT were decreased. GOT and GPT activities of T1 and T5 were decreased 6.1%, 17.8% and 25.4%, 32.4% compared with HF. On microstructure observing through the transmission electron microscope (TEM) of liver cell, in normal group, a normal large and clear nucleus, rough endoplasmic reticulum (RER) and mitochondria possessing well-defined double outer-limiting membranes were found. However, in HF, it was hard to observe the microstructures in cytoplasm, because of too many fat granules. It showed severely damaged cell, pyknotic nucleus, swollen disintegrating RER and mitochontria loosing the cristae. In T1, there were more repaired liver cells and less fat granules than HF. In T5, there were much less numbers and smaller size of the fat granules than T1, and the morphology was similar to normal cell.

This study was performed to investigate the effects of sea tangle (ST) extracts on serum lipid concentration in ovariectomized rats. Weight-matched female Sprague-Dawley strain rats were assigned to four groups. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with ST at 50 mg/kg body wt (OVX-ST50) and ovariectomized rats supplemented with ST at 200 mg/kg body wt (OVX-ST200). The activities of serum GOT and GPT were increased by ovariectomized. The serum GOT levels in OVX-ST50 and OVX-ST200 groups were decreased than OVX-control group. But GPT level was only decreased in the serum of OVX-ST200 group. Serum total cholesterol and triglyceride contents decreased in sham group compared with OVX-control group by ovariectomy. Six weeks feeding of ST extract resulted in a significant lowering of serum triglyceride and lowering tendency of total cholesterol Level. The serum HDL-cholesterol was higher in ST groups than OVX-control group. These results suggest that the beneficial effect of ST extract may be used to possibly improve on the lipid metabolic syndrome of menopausal women.

Many countries and companies are pursuing and developing Artificial intelligence as it is the core technology of the 4th industrial revolution. Global IT companies such as Apple, Microsoft, Amazon, Google and Samsung have all released their own AI assistant hardware products, hoping to increase customer loyalty and capture market share. Competition within the industry for AI agent is intense. AI assistant products that command the biggest market shares and customer loyalty have a higher chance of becoming the industry standard. This study analyzed the current status of major overseas and domestic IT companies in the field of artificial intelligence, and suggested future strategic directions for voice UI technology development and user satisfaction. In terms of B2B technology, it is recommended that IT companies use cloud computing to store big data, innovative artificial intelligence technologies and natural language technologies. Offering voice recognition technologies on the cloud enables smaller companies to take advantage of such technologies at considerably less expense. Companies also consider using GPT-3(Generative Pre-trained Transformer 3) an open source artificial intelligence language processing software that can generate very natural human-like interactions and high levels of user satisfaction. There is a need to increase usefulness and usability to enhance user satisfaction. This study has practical and theoretical implications for industry and academia.
