Mesenchymal stem cells (MSCs) can differentiate into neural cells to treat nervous system diseases. Magnetic resonance is an ideal means for cell tracking through labeling cells with superparamagnetic iron oxide (SPIO). However, no studies have described the neural differentiation ability of SPIO-labeled MSCs, which is the foundation for cell therapy and cell tracking in vivo. Our results showed that bone marrow-derived mesenchymal stem cells (BM-MSCs) labeled in vitro with SPIO can be induced into neural-like cells without affecting the viability and labeling efficiency. The cellular uptake of SPIO was maintained after labeled BM-MSCs differentiated into neural-like cells, which were the basis for transplanted cells that can be dynamically and non-invasively tracked in vivo by MRI. Moreover, the SPIO-labeled induced neural-like cells showed neural cell morphology and expressed related markers such as NSE, MAP-2. Furthermore, whole-cell patch clamp recording demonstrated that these neural-like cells exhibited electrophysiological properties of neurons. More importantly, there was no significant difference in the cellular viability and $[Ca^{2+}]_i$ between the induced labeled and unlabeled neural-like cells. In this study, we show for the first time that SPIO-labeled MSCs retained their differentiation capacity and could differentiate into neural-like cells with high cell viability and a good cellular state in vitro.

Background: The analgesic efficacy and safety of propacetamol, an injectable prodrug of acetoaminophen, in combination with intravenous morphine PCA were studied in 40 patients after gynecological surgery requiring lower abdominal incision. Methods: Using a double-blind, randomized, parallel-group design, the effects of four(every 6 hr) intravenous injections of 2 g propacetamol(=1 g acetoaminophen) were compared with four injections of placebo(PL) immediately after surgery. Efficacy of cumulative dose of morphine and number of boluses requested was assessed over 24 hours by automated recording on the PCA device. It was assessed on pain scores rated on a ten-point verbal scale along with vital signs, $K^+$, glucose, BUN, creatinine, PT and PTT were measured along with stress hormones(epinephrine, norepinephrine and cortisol). Results: There were no differences in demographic data between two groups. Propacetamol group demonstrated approximately 21% morphine sparing effect compared to placebo group($33.1{\pm}10.4$ mg vs $41.4{\pm}8.0$ mg). No significant differences noted in $K^+$, glucose, BUN, Creatinine, PT and PTT levels. There were significant increases in norepinephrine and cortisol in placebo group postoperatively, compared to preoperative values. At the same time, propacetamol group also showed significant changes in these hormones. Both group revealed high degree of patient satisfaction. Conclusion: Propacetamol showed significant morphine sparing effect to some degree. Side effects were much less in propacetamol group with subsequently high patient satisfaction. The secretion of stress hormone were not blocked by postoperative propacetamol injections. Authors concluded that propacetamol should be considered as an excellent adjuvant analgesics in postoperative pain control in opioid patient controlled analgesia.

Objectives The purpose of this study is to design a research to find clinical factors involved in the decision-making process for determining the constitutional prescription based on prospective clinical data. Methods We have created a draft of the case report form. Therefore, seven constitutional experts was interviewed for additional items to be important used to determine the constitutional prescription in clinic. Interviews were done from December 2012 to March 2014, experts per person 2-3 times, took time of about 120 minutes per interview. Since then, we developed the final case report form through the expert meeting. At the same time, the developing the electronic case report form (eCRF) and the protocol to collect constitutional treatment cases was also discussed. Results & Conclusions The items of the case report form were subject general, lifestyle, health measurement, record of expert, prescription and evaluation after medication. The part of the clinical symptoms of the record of expert allowed to be recorded in the 5-point scale for the collection of quantitative data as much as possible. Assuming a re-visit of the patient, if necessary, twice the recording were to be possible. At the same time, the eCRF and the protocol to collect constitutional treatment cases were also developed. In this study, it will be able to more objectively standardize the medical decision making process that the experts of constitutional prescription decision. As a result, it will be possible to provide the standardized constitutional medical services.

It has been known that RA, one of major constituents of Perilla frutescens which has been used as a traditional folk remedy for sedation in oriental countries, shows the anxiolytic-like and sedative effects. This study was performed to know whether RA may enhance pentobarbital-induced sleep through ${\gamma}-aminobutyric$ acid $(GABA)_A-ergic$ systems in rodents. RA (0.5, 1.0 and 2.0 mg/kg, p.o.) reduced the locomotor activity in mice. RA decreased sleep latency and increased the total sleep time in pentobarbital (42 mg/kg, i.p.)-induced sleeping mice. RA also increased sleeping time and number of falling sleep mice after treatment with sub-hypnotic pentobarbital (28 mg/kg, i.p.). In electroencephalogram (EEG) recording, RA (2.0 mg/kg) not only decreased the counts of sleep/wake cycles and REM sleep, but also increased the total and NREM sleep in rats. The power density of NREM sleep showed the increase in ${\delta}-waves$ and the decrease in ${\alpha}-waves$. On the other hand, RA (0.1, 1.0 and $10{\mu}g/ml$) increased intracellular $Cl^-$ influx in the primary cultured hypothalamic cells of rats. RA (p.o.) increased the protein expression of glutamic acid decarboxylase ($GAD_{65/67}$) and $GABA_A$ receptors subunits except ${\beta}1$ subunit. In conclusion, RA augmented pentobarbital-induced sleeping behaviors through $GABA_A-ergic$ transmission. Thus, it is suggested that RA may be useful for the treatment of insomnia.

의료인이 직접 환자를 진료하는 형태의 원격진료가 현행 의료법에서 허용이 되는지 여부와 의료법상 허용을 떠나 정책적으로 허용하는 것이 바람직한지의 문제가 오랫동안 논란이 되어 왔다. 그러다가 코비드19라는 인류가 드물게 겪는 팬데믹 상황으로 인하여 우리나라에서 한시적으로 허용이 되었고 외국에서도 이용이 폭발적으로 증가하면서 다시 관심을 받고 있다. 원격진료의 허용 여부에 관하여는 이미 많은 논문이 존재하지만, 막상 원격진료가 실시될 경우 그에 수반되어 발생할 수 있는 부수적인 법적 쟁점들에 관하여는 논의가 부족했던 부분이 있어 이 글에서 다루었다. 필자는 국민건강보험의 수가정책, 환자 본인 확인, 의약품 비대면 구매, 진료장면 녹화에 관하여는 입법적으로 미리 정비를 하는 것이 바람직하다고 보았고, 원격진료에 필요한 시설 기준은 오히려 법제화를 하면 현실에 뒤떨어지거나 변화에 대응하는 탄력성이 떨어지므로 법제화를 하지 않고 대신 의료인이 의료기기법상 승인을 받은 원격진료용 기기를 사용하는 것으로 충분하다고 판단하였으며, 끝으로 원격진료의 맥락에서 발생한 의료사고의 책임이라든가 개인정보 보호는 기존의 민사법이나 개인정보 보호법으로 이미 충분한 대응이 되므로 별도의 특칙을 제정할 필요는 없다는 결론을 내렸다.

The objective of this research was to compare the flushing effects using 1:1,000 diluted heparin or 0.9% normal saline in relation to needle gauge and frequency of IV medications. The comparative categories were clotting, duration of patency, and incidence of phlebitis. The design of research was a Nonequivalent Control group, Post test, Nonsynchrorized Design. The independent variable was 0.9% normal saline flushing the IV locks and the dependent variables were clotting, duration of patency, and incidence of phlebitis. Subjects were medical-surgical inpatients over 15 years old and with peripherally placed IVs who were hospitalized in a university medical center. Exclusion criteria included foreigners and those who were rejected for this research. The final sample for data analysis included 295 IV sites in 194 patients; 154 were in the saline group and 141 were in the heparin group. Subjects were assigned to have IV locks is flushed with 0.9% normal saline in the experimental group and to have IV lock flushed with 1:1,000 diluted heparin(100 units) in the control group. In order to increase reliability, the nurses who were assigned to the units involved in the study received an explanation on the standard method for locking an IV, recording method for observational data and criteria for the detection of phlebitis. Data were collected for a period of 2 weeks, from March 16, 2000 to March 29, 2000. Total duration of IV was defined the time of IV insertion to the time of discontinuation. Phlebitis was defined as the presence of the following : pain, swelling. erythema at the insertion site. Chi-square was used to determine the association between the degree of clotting, duration of patency, and incidence of phlebitis for the diluted heparin or the normal saline and needle gauge and frequency of IV medications. The results are summarized as follows : (a) There was difference in the degree of clotting between two groups($X^2=5.882$, p=.015). (b) There was no difference in the degree of duration of patency between two groups($X^2=2.439$, p=.295). (c) There was no difference in the incidence of phlebitis between two groups($X^2=0.190$, p=.663). (d) There was difference in the degree of clotting($X^2=6.209$, p=.013) and in the degree of duration of patency($X^2=6.978$, p=.031) according the needle guage between the two groups. (e) There was difference in the incidence of phlebitis($X^2=5.008$, p=.025) according to the frequencies of IV injection between two groups.

Purpose: The purpose of this study was to evaluate knowledge, attitude, and compliance regarding hand hygiene according to the profession of ICU health care providers. Method: Data were collected by questionnaires and by recording of direct observations of 143 health care providers in 4 intensive care units. With SPSS/WIN 12.0 t-test, ANOVA, and ${\chi}^2-test$ were used to analyze the data. Results: The level of knowledge regarding handwashing among the nurses was higher and a more positive attitude was shown compared to physicians. Overall handwashing compliance was low among all ICU health care providers, but nurses had better compliance than any other health care providers and significantly higher frequency for handwashing before care and after care activities. All of professions had lower scores on the appropriate length of time for handwashing and areas that need to be scrubbed. The level for nurses was medium and for physicians, the lowest of all professions. The appropriate agent for handwashing and the method of drying for handwashing compliance was high in all professions. Conclusion: The results suggest that multidisciplinary interventions are needed to develop an environment for appropriate handwashing as well as to reinforce importance of handwashing compliance for health care providers.

Spontaneous bursting activity was studied in rat thalamocortical slices using extracellular field potential recording to test the potential utilization of ginsenoside Rb$_1$ in controlling overactivated neural systems. In order to induce bursting activity, slices were perfused with Mg$\^$2+/-free artificial cerebrospinal fluid (ACSF). Two major types of spontaneous bursting activity, simple thalamocortical burst complexes (sTBCs) and complex thalamocortical burst complexes (cTBCs), were recorded in Mg$\^$2+/ -free ACSF. Ginsenoside Rb$_1$ selectively suppressed cTBCs. Duration and occurrence rate of cTBCs were reduced by 87.3${\pm}$10.2% and 85.3${\pm}$ 14.7% in the presence of 90 ${\mu}$M ginsenoside Rb$_1$ respectively, while amplitude and intraburst frequency were slightly changed by ginsenoside Rb$_1$. In contrast, ginsenoside Rb$_1$was much less effective in reducing duration and occurrence rate of sTBCs. We also tested effects of ginsenoside Rb$_1$ on bursting activity in the presence of a GABA$\sub$A/ receptor antagonist, bicuculline methiodide (BMI). Ginsenoside Rb$_1$ had no effect in suppressing BMI-induced bursting activities. These results suggest that ginsenoside Rbi may be useful in controlling seizure-like bursting activity under pathological conditions.
