The purpose of this descriptive research was to investigate importance awareness on peripheral intravenous infusion, and to identify the factors influencing on importance awareness among 128 children's hospital nurses. The collected data were analyzed with descriptive statistics, T-test, ANOVA, Pearson's correlation analysis and Hierarchical multiple regression using SPSS 21.0. Importance awareness on peripheral intravenous infusion of children's hospital nurses was the lowest in education, and the highest in hand hygiene. There were significant differences in subdomains of peripheral intravenous infusion according to marriage state, working department, position and final education(p<.001~.046), and there were positive correlations between education and importance awareness of peripheral intravenous infusion(p<.001). And factors affecting importance awareness were education(${\beta}=.446$) and working department(${\beta}=.247$), and explannation rate was 31.0%(p<.001). These results could be used as basic data of educational program on peripheral intravenous infusion for children's hospital nurses after repeated study.

Objectives: The purpose of this study is to investigate the mechanism of acupuncture for treating chemotherapy-induced peripheral neuropathy. Methods: Based on domestic and international papers reported until October 2020, experimental papers on "chemotherapy induced peripheral neuropathy", "mechanism", and "acupuncture" were set up to identify the mechanisms of chemotherapy induced peripheral neuropathy. A total of seven papers were selected and searched: one pilot paper for people and six experimental papers for rats. Results: In the pilot paper studied by Bao, T., the effect of EA was demonstrated but no significant results were produced for the mechanism. Moon et al. derived the association between EA and plasma 𝛽-endorphin in rat experimental studies on oxalilatin-induced cold hypersensitivity. Meng et al. found relevance to 𝜇, 𝛿, and 𝛿 opioid through EA stimulation in paclitaxel-induced peripheral neuropathy. Lee et al. studied the relationship between EA and muscarin and 5-HT in rat experiments on oxaliplatin-induced coldness, associated with 5-HT and EA, especially with 5-HT3 receptors. Choi et al. revealed the association of adrenaline and opioid acting on 𝛼2- and 𝛽 adrenaline receptors with EA in rat experiments on paclitaxel-induced neuralgia. In rat experiments on oxaliplatin-induced neuralgia reported by Lee, 𝛽-endorphin and encephalin were studied to be mediated by EA. Zhang, T. et al. revealed in the paclitaxel induced rat experiment that EA activates 5-HT. Conclusion: It is inferred that peripheral neuropathy caused by anticancer drugs can be reduced by activating the action of 5-HT, 𝛽-endorphin, and encephalin through the descending inhibitory pathways. cell differentiation, herbal medicine, Pongamia, stem cells

Background: Osteomas are benign, slow-growing bone tumors that can be classified as central, peripheral, or extraskeletal. Central osteomas arise from the endosteum, peripheral osteomas from the periosteum, and extraskeletal osteomas within the muscle. Frontal peripheral osteomas are mainly encountered in plastic surgery. In this study, we retrospectively analyzed the clinical data of patients with frontal peripheral osteomas. Methods: We retrospectively reviewed the medical records of patients who visited our hospital with frontal peripheral osteomas between January 2014 and June 2022. We analyzed the following variables: age, sex, tumor type (sessile or pedunculated), single or multiple, size, history of head trauma, operation, and recurrence. Results: A total of 39 patients and 41 osteomas were analyzed, of which 29 osteomas (71%) were sessile and 12 osteomas (29%) were pedunculated. The size of the osteomas ranged from 4 to 30 mm, with an average size of 10 mm. The age of patients ranged from 4 to 78 years with a mean age of 52 years. There were seven men (18%) and 32 women (82%), and the man-to-woman ratio was 1:4.6. Two patients (5%) had multiple masses, with two osteomas in each, while only two patients (5%) had a history of head trauma. Twenty-nine patients (74%) underwent ostectomy by a direct approach, and none of the patients experienced recurrence. Conclusion: The epidemiologic data of our study will help plastic surgeons encounter frontal peripheral osteomas in the field to provide proper management for their patients.
Non-neuronal high affinity binding sites for benzodiazepines have been found in many peripheral tissues including cardiac muscle and vascular smooth muscle, and have been designated as 'peripheral benzodiazepine receptor'. Benzodiazepines have been shown to induce relaxation of the ileal, vesical, and uterine smooth muscles. However, it is still unclear about possible involvement of peripheral benzodiazepine receptor on the contractility of trachealis muscle. This study was performed to investigate the role of the peripheral benzodiazepine receptor on the contractility of canine trachealis muscle. Canine trachealis muscle strips of 15 mm long were suspended in an isolated organ bath containing 1 ml of physiological salt solution maintained at $37^{\circ}C$, and aerated with $95%\;O_2/5%\;CO_2$. Isometric myography was performed, and the results of the experiments were as follows: Ro5-4684, FGIN-1-27 and clonazepam reduced a basal tone of isolated canine trachealis muscle strip concentration dependently, relaxant actions of RoS-4684 and FGIN-1-27 were antagonized by PK11195, a peripheral benzodiazepine receptor antagonist. Flumazenil, a central type antagonist, did not antagonize the relaxant action of Peripheral type agonists. Saturation binding assay of [3H]Ro5-4864 showed a high affinity$(Kd=5.33{\pm}1.27nM,\;Bmax=\;867.3{\pm}147.2\;fmol/mg\;protein)$ binding site on the canine trachealis muscle. Ro 5-4684 suppressed the bethanechol-, 5-hydroxyoyptamine- and histamine- induced contractions. Platelet activating factor (PAF) exerted strong and prolonged contraction in trachealis muscle strip. Strong tonic contraction by PAE was attenuated by Ro 5-4684, but not by WEB 2086, a PAF antagonist. Based on these results, it is concluded that the peripheral benzodiazepine receptor mediates the inhibitory regulation of contractilty of canine trachealis muscle.

Autologous peripheral blood stem cell transplantation (PBSCT) has been used as a major treatment strategy for hematological malignancies. The number of CD34 positive cells in the harvested product is a very important factor for achieving successful transplantation. We studied the factors that can predict the number of CD34 positive cells in the harvested product of acute myelocytic leukemia (AML), multiple myeloma (MM) and Non-Hodgkin's lymphoma (NHL) patients after mobilizing them with chemotherapy plus G-CSF. A total of 73 patients (AML 19 patients, MM 28 patients, NHL 26 patients) with hematological malignancies had been mobilized with chemotherapy and granulocyte colony-stimulating growth factor from April, 2000 to February, 2012. Group's characteristics, checkup opinion of pre-peripheral blood on the day of harvest & outcome of PBSC were analyzed and evaluated using SPSS statistics program after grouping patients as below; group 1: CD34 cell counts < $2{\times}10^6/kg$ (n=16); group 2: $2{\times}10^6/kg{\leq}CD34$ cell counts < $6{\times}10^6/kg$ (n=32); group 3: CD34 cell counts ${\geq}6{\times}10^6/kg$ (n=25). We analyzed the clinical characteristics, the peripheral blood (PB) parameters and the number of CD34 positive cells in the PB and their correlation with the yield of CD34 positive cells collected from the mobilized patients. The total number of leukapheresis sessions was 263 (mean: 3.55 session per patient), and the mean number of harvested CD34 positive cells per patient was $7.37{\times}10^6/kg$. The number of CD34 positive cells in product was significantly correlated with the number of platelet and CD34 positive cells in peripheral blood (P<0.05). The number of PB CD34 positive cells was the best significant factor for the quantity of harvested CD34 positive cells on the linear regression analysis (P<0.05). Many factors could influence the mobilization of peripheral blood stem cells. Platelet count and PB CD34 positive cells count were the two variables which remained to be significant in multivariate analysis. Therefore, the number of platelet and CD34 positive cells in peripheral blood on the day of harvest can be used as an accurate predictor for successful peripheral blood stem cell collection.
Ketamine, one of general anesthetics for human and veterinary use, is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist which interferes with the action of excitatory amino acids. It has been reported to impair various leukocyte functions. In this study, the effect of ketamine on the oxidative burst activity (OBA) of canine peripheral blood leukocytes was examined. The OBA of canine peripheral blood phagocytes was analyzed by flow cytometry system. Ketamine at higher concentration such as $1,000{\mu}M$ exhibited a low viability of leukocytes. Thus, ketamine was used at concentration of 10 to $500{\mu}M$ showing no cytotoxic effect and high cell viability. The OBA of leukocytes in the presence or absence of latex beads was analyzed by addition of dihydrorhodamine 123. The direct treatment of ketamine revealed the inhibitory effect on the OBA of peripheral blood polymorphonuclear cells (PMN) and monocyte-rich cells but not peripheral blood mononuclear cells (PBMC) in the presence of latex beads. However, when latex beads were not added to PMN, its OBA was not inhibited by ketamine. The OBA of PMN and monocyte-rich cells but not PBMC in the presence of latex beads was also inhibited by culture supernatant from ketamine-treated- PBMC but not -PMN. But the OBA of PMN in the absence of latex beads was not inhibited by culture supernatant from PBMC treated with ketamine. Therefore, these results suggested that ketamine has the inhibitory effect on the OBA of canine peripheral blood phagocytes such as neutrophils and monocytes during phagocytic response.
Previously, we had reported that the electrical stimulation of peripheral nerve with stimlatory parameters of 20 V strength and 2 Hz frequency for 60 min resulted in reducing the pain reaction. The present study was performed to evaluate if the pain reaction was affected by the peripheral nerve stimulation with different stimulatory parameters in the decerebrated cat. The flexion reflex was used as an index of the pain reaction. The reflex was elicited by stimulating the sural nerve (stimulus strength of 20 $V\;\times\;0.5$msec) and recorded as a compound action potential from the motor nerve innervated to the posterior biceps femoris muscle. The common perneal nerve was selected as a peripheral nerve on which the electrical stimulation of various intensities and frequencies was applied. The results are summarized as follows : 1) The peripheral nerve stimulation with 100 mV strength, regardless of frequencies, did not affect the pain reaction induced by the sural nerve stimulation. 2) When the stimulus of 1V intensity and slow frequency (2 Hz) was applied to the peripheral nerve for 30 min or 60 min, the pain reaction was significantly reduced comparing to the control. However, this reduced pain reaction by the peripheral nerve stimulation was not reversed by the injection of naloxone (0.02 mg/kg) 3) High frequency stimulus (60 Hz) of 1V intensity for 30 or 60 min did not show any effects of affecting the pain reaction. These results suggest that the stimulus of relatively high intensity (at least 1V) and low frequency (2 Hz) is needed to elicite the analgesic effect by the peripheral nerve stimulation. By the 1V stimulus, $A\delta$ nerve fiber is activated. Therefore, an $A\delta$ or smaller nerve fibers must be activated for showing analgesia by the peripheral nerve stimulation. However, the mechanism of analgesia by the $A\delta$ nerve activation alone was not related to the endogeneous morphine system since the reduced pain reaction by the $A\delta$ fiber activation alone was not reversed by the treatment of naloxone.

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.
Thirty cases were observed among the peripheral facial paralysis patients who admitted. the Department of Acupuncture and Moxibustion of Seoul Oriental Hospital between Feb. 2nd, 1995 and Aug. 14th, 2000. These patients were divided into two groups; the first group was treated with indirect facial moxibustion., while the second with basic oriental-westem medicine treatment. Object : To improve the therapeutic rate of peripheral facial paralysis by applying basic oriental-western medicine treatment and indirect facial moxibustion. Method : Inpatients suffering from peripheral paralysis of facial nerve were divided into two groups; both groups recieved basic oriental-western medicine treatment; the experimental group additionally received indirect facial moxibustion onto Tuyu(頭維) and Chich'ang(地倉) once or twice daily. Result : In the therapeutic result from moxibustion treatment group, 3 excellent, 7 good, 3 fair, and 1 poor case were observed. From compound treatment group, 2 excellent, 5 good, 5 fair and 4 poor cases were observed. Among the excellent and good patients of both groups, therapeutic rate of moxibustion treatment group (71.4%) was higher than that of compound treatment group(43.8%). Conclusion : The overall therapeuric rate of the moxibustion treatment group was 92.8%, which was higher than that of the compound treatment group(75.1%).
Objectives : This study was done for reporting the effect of bloodletting therapeutics on peripheral facial paralysis patients with back of the affected ear pain. Methods : We investigated 37 cases of peripheral facial paralysis patients with postauricular pain, and devided patients into two groups : We treated one group by complex oriental medical treatment with bloodletting therapeutics, and did the other group by complex oriental medical treatment without bloodletting therapeutics.
