  • The growth responses of a variety of human intestinal bacteria to extracts of Panax ginseng and five other oriental medicinal Araliaceae were elraluattd in vitro and in vivo. The extracts enhanced the growth of Brifidobnnerilrm breve and B. longlim in media with or without carbon sources, suggesting that bifidus factors) might be involved in the phenomenon. This effect was most pronounced with water extract of P. ginseng, the growth of 27 bifidobacteria strains belonging to B adolescentis, B. longum, B. brim and B. infantis being greatly stimurated, whereas seven B. bifidum strains and other bacteria such as clostridia and Escherichin soli had little or no ability to utilise it for growth. Methanol extracts of p. ginseng were found to selectively inhibit growth of various clostridia including bifidobacteria. Paraputrificum, but this effect was not observed on other bacteria including bifidobacteria. The effect of ginseng extract intake (600 mg/day for two weeks) on the faecal microflora, pH, volatile fatty acids, ammonia, putrefactive products, and -glucuronidase, -glucosidase and nitroreductase activities, and on the blood components (triglyceride, total cholesterol and ammonia) were investigated using seven healthy human volunteers. The total concentration of faecal microflora including Bifidnkaderiifm app. during the period of ginseng extract intake %twas significantly unaffected from the preceding and subsequent control peroids. However, the frequency of occurrence of subjects having C. perfringens was significantly decreased. The faecal pH value was also significantly decreased, suggesting that the intake might increase the activity of Bifidobncterium spry. Other biochemical properties in faeces did not changed significantly. The levels of ammonia and triglycerid in blood were decreased with ginseng extract intake. These results may be an indication of at least one of the Pharmacological actions of p. ginseng as an adaptogen.

  • Photo-plethysmography (PPG), which measures changes in the peripheral blood flow of a human body using difference in absorption rate of light, is a measurement method that is studied and used in clinical and various applications due to its simple circuit configuration and measurement convenience. Magneto-plethysmography (MPG), which is newly developed by our team, is a method of measuring changes in the conductivity of biological tissues by using a eddy current induced by a time-varying magnetic field, and is not subject to optical interference. In this study, we investigated the detection characteristics of MPG according to the change of the conductivity of the object and fluid to be measured by simultaneously measuring PPG and MPG. In order to control the speed of fluid known in advance, a blood flow simulator was implemented and used. The fluid used in the experiment was general mineral water and physiological saline (0.9% NaCl) solution. Experimental results show that the amplitude change of the measured PPG was 0.3% in normal water and saline solution, and that of MPG was 77.3%. Therefore, it is considered that the magneto-plethysmography (MPG) has a strong correlation with the conductivity of the fluid.

  • This study was conducted to examine the hematological factors in cultured olive flounder Paralichthys olivaceus depending on its growth stage and season. The study also aims at developing the standard hematological indicator for growth stage and season by examining total 16 parameters including whole blood (hematocrit, red blood cell and hemoglobin), biochemical (glucose, cholesterol, total protein, AST, ALT, $Na^+,\;K^+,\;Cl^-,\;Ca^{2+},\;Mg^{2+}$ and osmolarity), and endocrine (cortisol and $T_3$) factors in plasma of cultured olive flounder. The result showed a growth stage-dependent increase of $T_3$ level in olive flounder while the level of cholesterol showed an inverse correlation to fish size. For seasonal fluctuation in cultured olive flounder of the same growth stage, the highest level of Ht and RBC was observed in autumn.

  • Silicone Rubber (SR)-based potassium- and sodium-selective solid-state electrodes have been developed for the portable blood electrolyte analyzer system. The electrochemical performance of these electrodes have been evaluated with a static experimental setup and with the newly developed blood electrolyte analyzer system (model; HS603). It has been shown that their potentiometric properties are essentially comparable to those of PVC-based ion-selective electrodes, but with greatly improved lifetime (200 and 40 days for potassium and sodium sensors, respectively) and potential stability (within $\pm0.1$ mV). Clinical tests have been performed with real serum samples and the results have been compared with those obtained from Ciba-Corning BGA 288 system; correlations were excellent, proving its practical utility as a new commercial system.

  • Pulpotomy is a frequently used treatment modality in primary teeth. It is method by which infected coronal pulp is removed while retaining vital radicular pulp. Since its introduction in 1930 by Sweet formocresol remains the most popular medicament for this treatment. However, despite its outstanding bactericidal properties, formocresol is known to cause adverse tissue reactions. Theoretically, formocresol disinfects and fixes radicular pulp and thus prevents infection and internal resorption. In reality, however, it leads to chronic inflammation and is sometimes responsible for failures through abscess formation and internal root resorption. Also, Myers et al., in 1978, reported on the systemic distribution of FC and other studies have followed with reports of its immunological, mutagenic and carcinogenic effects. Much effort has, therefore, focused on the development of alternative medicaments and techniques. Since its introduction in 19C, ferric sulfate proven itself as an effective hemostatic agent and is used as an astringent in dentistry. In 1988, Landau and Johnsen suggested ferric sulfate be used as a medicament in pulpotomy and many studies have focused on it to overcome the toxic effects of FC. Ferric sulfate acts through its ferric ion and iron ion, which react with blood protein leading to aggregation. The aggregated protein acts to plug the blood vessels, causing mechanical hemostasis. As blood clot formation is minimal, there is reduced inflammation of radicular pulp and enhanced healing. There are no reports regarding its systemic distribution. This is a report of cases treated by the author using pulpotomy with ferric sulfate.

  • Objective & Methods : In the point of several medical books included 'Internal Classic' and Hyungsang medicine, the writer studied about meridian theory and it's disorders, after adapting to acupuncture and herb medicine. Results : 1. Dr. Jisan explained concretely physiological and pathological meridian appearances with using metaphor about phenomenons of nature and human living. 2. Shapes corresponding to meridian are considered as Yukkyunghyung formed by more or less of vigor and blood, and by tendency of up and down in eyes and nose, and also contained diseases of viscera and characters. 3. The colors connected with meridian are changed according to conditions, and meridian is seen through colors. And then colors is the properties of vital energy and symbol of spirit, that is expressed as aspect of essence, vigor, spirit and blood, as the original color of five viscera, as the colors of four seasons and as the colors of diseases. So the changes of feelings are appeared to meridian flow. 4. The method of examining pulse for meridian disorders is applied to Jisan diagram. Jisan diagram is devised from mutual communication of viscera and connection with inside and outside. It is conjugated widely in clinical examination to be distinguished into Dam-Bangkwang, into diseased part of viscera and into meridian. Also it is conjugated recuperation of diseases. 5. The meridian diseases are appeared all the distributed parts of meridian, especially skin, hair, eyebrow, and the ends of the extremities which are sensitive to stimulus. The causes are the disharmony between vital energy and blood and the discordance of six atmospheric variation. The symptoms are skinny aches, itching and eruption, etc. Conclusions : The acupuncture of Hyungsang medicine which utilizes classification of shapes, examining pulse according to Jisan diagram and demonstration of symptoms, is very effective and required systematical study from now on.

  • A Gompertz modeling, sigmoid in shape, is a widely used application for social science, natural science, engineering, and medical research to allow confident approximation and accurate analysis and has been applied to estimate an elderly population on aging of population. Due to the high toxicity of currently available drug delivery vehicles, various efforts have been made to reduce side-effects in clinical fields, but its application to preclinical and clinical studies is limited and there are some difficulties to optimize the parameters of Gompertz modeling applicable to preclinical studies. Therefore, in this study, we demonstrated the ability of sickle red blood cells loaded by hypotonic dialysis then photosensitized and light-activated ex vivo for controlled release and simultaneously optimized Gompertz function to evaluate controlled drug release properties of photosensitized sickle red blood cells to reduce pain-related treatments in cancer patients.

  • Far-infrared radiation therapies are becoming more popular for blood circulation disorders, cardiovascular disease, skin diseases, inhibit cancer cell, etc replacing conventional operations. In this research, thermal characteristics of heating part in panel radiators, which is effective on the blood circulation disorders were experimentally analyzed. The heating line supplies heat energy to insulation coatings with heat flux of $150mW/m^2$ in normal status and as a result the coatings reached 20% of the heating line temperature. In other words, the insulation itself could increase surface temperature of heating plates by 20% and raise thermal time constant promote blood circulation effect. We also found that space arrangement of the heating lines was an important factor in designing heating parts and both coefficient of heat conduction and density of the heating plate should be also considered for superimpose of thermal diffusion.

  • The SPP003 is a mixture of water extract from Schizandrae Fructus, Poligoni multiflori Radix, Ginseng Radix Akba and Hoelen. The aim of this study was to investigate the anti-hyperglycemic effect of SPP003 in normal and streptozotocin (STZ)-induced diabetic rats, and to monitor the toxicity of SPP003. Oral glucose tolerance test (OGTT) was performed after oral administration of SPP003 100, 300, 600 and 900 mg/kg in normal rats. Blood glucese concentration was measured at -30 min (vehicle, SPP003 or tolbutamide 60 mg/kg, 0 min (glucose treatment), 60, 120 and 180 min. Rats were administerd STZ 65mg/kg (0.1M citrate buffer, pH 4.5) intraperitoneally to induce diabetes and administered vehicle, Spp003 (100, 300 and 600 mg/kg) or tolbutamide (60 mg/kg) orally once a day for 4 weeks. Blood glucose level was measured a 0, 4, 7, 14, 21 and 29 day after initial drug administration. A single oral toxicity of SPP003 was studied in Sprague-Dawley rats of both sexes. In this study, rats were administered with doses of 1, 2 and 5 g/kg of SPP003. In glucose tolerance test, SPP003 900 mg/kg markedly decreased glucose concentration at 1 hr after glucose treatment. Blood glucose levels were much higher in STZ-diabetic rats. These increases were significantly attenuated by SPP003 600 mg/kg. SPP003 did not show any signigicant toxicity. These findings suggest that SPP003 has hypoglycemic properties in STZ-diabetic rats.

  • Background: We investigated the tolerability and pharmacokinetic properties of various ginsenosides, including Rb1, Rb2, Rc, Rd, and compound K, after single or multiple administrations of red ginseng extract in human beings. Methods: Red ginseng extract (dried ginseng > 60%) was administered once and repeatedly for 15 days to 15 healthy Korean people. After single and repeated administration of red ginsengextract, blood sample collection, measurement of blood pressure and body temperature, and routine laboratory test were conducted over 48-h test periods. Results: Repeated administration of high-dose red ginseng for 15 days was well tolerated and did not produce significant changes in body temperature or blood pressure. The plasma concentrations of Rb1, Rb2, and Rc were stable and showed similar area under the plasma concentration-time curve (AUC) values after 15 days of repeated administration. Their AUC values after repeated administration of red ginseng extract for 15 days accumulated 4.5- to 6.7-fold compared with single-dose AUC. However, the plasma concentrations of Rd and compound K showed large interindividual variations but correlated well between AUC of Rd and compound K. Compound K did not accumulate after 15 days of repeated administration of red ginseng extract. Conclusion: A good correlation between the AUC values of Rd and compound K might be the result of intestinal biotransformation of Rb1, Rb2, and Rc to Rd and subsequently to compound K, rather than the intestinal permeability of these ginsenosides. A strategy to increase biotransformation or reduce metabolic intersubject variability may increase the plasma concentrations of Rd and compound K.
