  • 케타민은 N-methyl-D-aspartate (NMDA) 수용체의 비경쟁적인 길항제로 인의와 수의학에서 전신 마취제로 사용하는 약물이다. 본 연구진은 이전에 케타민이 개 말초혈액 백혈구의 순간산소과소비현상(oxidative burst activity)을 손상시킨다고 보고하였다. 현재 연구에서는 개 말초혈액 탐식세포의 탐식능(phagocytic capacity)에 대한 케타민의 효과를 검토하였다. 탐식능은 유세포 분석기로 분석하였다. 말초혈액 다형핵백혈구(peripheral blood polymorphonuclear cells; PMN)와 단구(monocytes)의 탐식능은 케타민의 직접 처리에 의해 감소하였으나 단핵구세포(peripheral blood mononuclear cells; PBMC) 분획에서의 탐식능은 케타민의 직접 처리에 의해 변화가 없었다. 말초혈액 다형핵백혈구와 단구의 탐식능은 케타민을 처리한 단핵구세포 배양상층액에 의해서도 감소하였다. 이상의 결과로부터 케타민은 호중구와 단구와 같은 개 말초혈액 탐식세포의 탐식능에 있어 직접적인 억제효과를 나타내며, 또한 케타민 처리 단핵구세포로부터 생산되는 가용성인자에 의해서도 탐식세포의 탐식능이 억제되는 것으로 사료되었다.

  • Peripheral neuropathy is a disease of multiple Peripheral nerves. Tingling, pins-and needles, numbness, burning and raw sensation are symptoms of peripheral neuropathy. These symptoms are frequently complained by patients who suffered from obstructive syndrome of Ki and blood (痺證). This case was reported to evaluate the effects of oriental medicine therapy on a patient with obstructive syndrome of Ki and blood (痺證). The subject was a female patient who had obstructive syndrome of Ki and blood (痺證). She complained of calf pain, cold sense, walking discomfort, insomnia, dyspepsia, anorexia etc. We administered the medicine with dispeling the cold pathogenic factor (寒邪), adjusting the constructive and defensive energy (調營衛), tonifying the Ki and blood (補氣血) by stage. After the treatment, the symptoms improved. This case suggests that oriental medicine therapy can be applicable to improve in symptoms with Peripheral neuropathy.

  • We measured radial arterial pulse signals using a prototype of a clip-type pulsimeter equipped with a permanent magnet and a Hall device, which produced signals through a voltage-detecting circuit. The systolic peak time and the reflective peak time for a temporally pulsed signal were analyzed for an arbitrary pulse wave at one position of a small permanent magnet. The measured value of the peripheral pulse wave velocity was about 1.25-1.52 m/s, demonstrating the accuracy of this new method. To measure the peripheral blood flow velocity, we simultaneously connected the radial artery pulsimeter to a photoplethysmography meter. The average value of the peripheral blood flow velocity was about 0.27-0.50 m/s.

  • Purpose: This study was done to investigate the effect of self-foot reflexology on peripheral blood circulation, peripheral neuropathy and to determine the feasibility of self-foot reflexology as a nursing intervention. Method: This was nonequivalent control pretest-posttest study with 76 patients with type 2 diabetes mellitus (ages between 40-79) recruited from public health centers in Busan city. Intervention was a 6 week self-foot reflexology, and outcome variables were peripheral blood circulation and peripheral neuropathy(tactile response to monofilament, intensity of symptoms of peripheral neuropathy). ANCOVA was used to do the statistical analysis. A.05 significance level was set for evaluating the effects of self-foot reflexology. Results: The self-foot reflexology was relatively effective not only in reducing peripheral neuropathy(especially tingling sensation and pain) but also in improving ability to sense the 10-g force monofilament. Conclusion: Even though self-foot reflexology was not effective in improving peripheral circulation, it had good effect on improving peripheral neuropathy. Therefore self-foot reflexology can be used as a nursing intervention program for promoting foot care for patients with DM patients.

  • This study is attempted to correct an error of electronic blood pressure meter with an optical sensor. In general, for a hospitalized patient, ECG, blood pressure, oxygen saturation, and respiration are basically measured to monitor the patient's condition. Opening of a blood vessel after it is occluded by pressurizing the cuff influences the blood flow of peripheral blood vessels as well as oscillation changes in the cuff. Blood vessels are occluded and peripheral blood flow disappears at cuff pressure above the examinee's blood pressure, while blood vessels are opened and peripheral blood flow appears again at cuff pressure under the examinee's blood pressure. Then Disappear-Appear Point Length(DAPL) of peripheral blood flow can be judged with the signal of peripheral blood flow, thus is available as a factor of error correction for electronic blood pressure meter. Also, systolic or diastolic blood pressure can be corrected with Appear-Point-Pressure(APP) of cuff pressure at a point where blood flow occurs and Appear-Maximum Pressure(AMP) of cuff pressure at the maximum amplitude point of peripheral blood flow after peripheral blood flow appears again. For verification, 27 examinees were selected, and their blood value was obtained through experimental procedure of 4 stages including induction of blood pressure change. The examinees were divided into two groups of experimental group and control group, regression analysis was conducted for experimental group, and correction of a blood pressure error was verified with optical signal by applying the regression equation calculated in experimental group to control group. As an experimental result, mean of the whole measurement errors was 5mmHg or more, which did not meet the standard fur blood pressure meter. As a result of correcting blood pressure measurements with data of DAPL, APP, and AMP as drawn out of PPG signal, systolic blood pressure, mean blood pressure, and diastolic blood pressure were $-0.6{\pm}4.4mmHg,\;-1.0{\pm}3.9mmHg$ and $-1.3{\pm}5.4mmHg$, respectively, indicating that mean of the whole measurement errors was greatly improved, and standard deviation was decreased.

  • Traditional Chinese medicine classifies peripheral nerve impairment as paralysis and arthromyodynia, and considers that it is the result of defects of meridians and vessels, QI and blood, bones and muscles. Huangqi (Astragalus) Guizhi (Cassia Twig) Wuwu Tang, as a Qi invigorating formula, is usually used to improve peripheral nerve impairment. In recent years, some scholars have conducted research into Chemotherapy-induced peripheral neuropathy (CIPN) treatment with Huangqi Guizhi Wuwu Tang and certain values of this treatment approach have been identified. CIPN is a type of blood-arthralgia Zheng in traditional Chinese medicine theory. In this review, we will discuss the treatment of CIPN with Huangqi Guizhi Wuwu Tang according to blood-arthtalgia Zheng.

  • Stroke is usually associated with the cerebral blood flow of the central nervous system. However, studies concerning the effects of neurologic sysmptoms induced from stroke on the peripheral blood flow has not taken place sufficiently. To ascertain the feasibility of a blood flow meter adopting to use doppler ultrasonogrphy, under the prospect that hemiparesis induced from stroke may have effect on the peripheral blood flow, the peripheral blood flow velocity was observed. The control group made up of healthy people without any factors capable of effecting the peripheral blood flow velocity, and patient group which consist of hemiparetic people induced from stroke, were recruited. Volumes of recruitment are 21 persons in the patient group, and 29 persons in the control group, but the final numbers of people are 17 and 21 respectively because of the inconsistancy in the method of the test. The non-invasive method of Doppler effect of Ultrasound was used to measure the blood flow velocity. The blood flow velocity in the peripheral part of left and right fourth fingers:dorsal branches of proper palmar digital artery to dorsum of distal phalanges, was measured in the control group and patient group through Doppler Ultrasound. In comparison of the control group and the patient group, the systolic blood flow velocity from the peripheral part of the upper extremity was lower in the patient group than that of the control group. According to such results, it is concluded that hemiparesis induces the reduction of the peripheral blood flow velocity in the systolic phase.

  • Purpose: Peripheral blood stem cell transplantation (PBSCT) has been widely used. The optimal time for collection is a critical factor to obtain proper counts of CD34 cell by peripheral blood stem cell collection (PBSC). The purpose of this study was to identify the factors influencing peripheral blood stem cell collection in order to figure out the more effective timing for PBSC. Method: The subjects of this study were 189 patients undergoing 3 leukapheresis from January 28, 2005 to December 31,2006. Group's characteristics, checkup opinion of pre-peripheral blood on the day of harvest & outcome of PBSC were analyzed and evaluated using SAS statistics program after grouping patients as below; group 1-CD34 cell counts $<2{\times}10^6/kg$ (n=97); group $2-2{\times}10^6/kg$ ${\leq}CD34$ cell counts $<4{\times}10^6/kg$ (n=26); group 3-CD34 cell counts ${\geq}4{\times}10^6/kg$ (n=63). Results: Based on outcome of peripheral blood stem cell according to diagnosis, acute myelocytic leukemia (AML) was 65.5% at Group 1, Lymphoma was 21.7% at Group 2 and multiple myeloma (MM) was 70.8% at Group 3. There were significant differences in CD34 cell counts according to diagnosis (p=0.00004). Type of cytokine mobilization according to diagnosis, Lenograsim was using 62.5% of MM & 38.2% of AML and filgrastim is using 22.0% of AML only. Circular peripheral blood CD34 cell counts prior to harvest was $258.1/{\mu}L$ at Group 3 which was much higher comparing to Group 1 ($10.5/{\mu}L$) and Group 2 ($39.9/{\mu}L$) (p<0.001). TNC counts of collected peripheral blood stem cell was $15.36{\times}10^6/kg$ at Group 3 and it's much higher than Group 2 ($13.16{\times}10^6/kg$) and Group 1 ($12.36{\times}10^6/kg$) (p=0.083). There was no significant difference in MNC counts inbetween 3 groups. Conclusions: Circular peripheral blood CD34+ cell counts prior to harvest was much higher at Group 3 than Group 1 and Group 2. Therefore, the number of CD34+ cells on the day of harvest can be used as an accurate predictor for peripheral blood stem cell.

  • To compare the respiratory burst activity potential of the phagocytes isolated from head kidney, spleen, and peripheral blood 1ll cultured rockfish (Sebastes schlegeli), chemiluminescent (CL) response analysis was performed. The phagocytes isolated from peripheral blood showed greater and faster CL response to the opsonized zymosan compared to that of the phagocytes isolated from kidney or spleen. This may imply a significant role of the blood phagocytes in defence mechanism of rockfish. The different responses found in the CL analysis among the phagocytes isolated from peripheral blood, kidney, and spleen may reflect differences in activation state or activity of phagocytes.
