Objectives: Radix Ginseng has been traditionally used as an adaptogen that acts on the adrenal cortex and stimulates or relaxes the nervous system to restore emotional and physical balance and to improve well-being in cases of degenerative disease and/or old age. Radix Ginseng has been used for a long time, but the safety of ginseng pharmacopuncture needs testing. This study was done to analyze the single-dose toxicity of water- soluble ginseng pharmacopuncture (GP) intramuscular injections in rats. Methods: All experiments were performed at Biotoxtech, an institution authorized to perform non clinical studies under the regulations of Good Laboratory Practice (GLP). Each group contained 10 Sprague-Dawley rats, 5 males and 5 females. GP was prepared in a sterile room at the Korean Pharmacopuncture Institute under regulations of Good Manufacturing Practice (GMP). GP dosages were 0.1, 0.5 and 1.0 mL for the experimental groups; normal saline was administered to the control group. The animals general condition was examined daily for 14 days, and the rats were weighed on the starting day and at 3, 7 and 14 days after administration of the pharmacopuncture. Hematological and biochemistry tests and autopsies were done to test the toxicological effect of GP after 14 days. This study was performed with approval from the Institutional Animal Ethics Committee of Biotextech. Results: No deaths were found in this single-dose toxicity test of intramuscular injections of GP, and no significant changes in the general conditions, body weights, hematological and biochemistry tests, and autopsies were observed. The local injection site showed no changes. Based on these results, the lethal dose was assumed to be over 1.0 mL/animal in both sexes. Conclusion: These results suggest that GP is relatively safe. Further studies, including a repeated toxicity test, are needed to provide more concrete evidence for the safety of GP.

Objectives: This study was performed to analyze the toxicity of the test substance, anti-inflammatory pharmacopuncture (AIP), when used as a single intramuscular-dose in 6-week-old, male and female Sprague-Dawley rats and to find the lethal dose. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices. Twenty (20) female and 20 male Spague-Dawley rats were divided into 4 groups of five 5 female and 5 male animals per group. The rats in the three experimental groups received single intramuscular injections with 0.1-$m{\ell}$, 0.5-$m{\ell}$ and 1.0-$m{\ell}$/animal doses of AIP, Groups 2, 3, and 4, respectively, and the control group, Group 1, received a single intramuscular injection with a 1.0-$m{\ell}$ dose of normal saline. Clinical signs were observed and body weight measurements were carried out for 14 days following the injections. At the end of the observation period, hematology, clinical chemistry, histopathological tests and necropsy were performed on the injected parts. Results: No deaths occurred in any of the groups. Also, histopathological tests showed that AIP had no effect on the injected parts in terms of clinical signs, body weight, hematology, clinical chemistry, and necropsy. Conclusions: As a result of single intramuscular-dose tests of the test substance AIP in 4 groups of rats, the lethal dose for both males and females exceeded $1.0m{\ell}$/animal. Therefore, AIP is a relatively safe pharmacopuncture that can be used for treatment, but further studies should be performed.

Effectiveness of the videotaped-record learning method in teaching intramuscular injection skill was investigated using an experimental research methodology. Data was collected from 57 female students attending Fundamental nursing class from two depts. of nursing in Chung-ju and Seoul. The subjects were assigned to two groups, the experimental group of 30 and the control group of 27. The independent variable was videotaped-record learning method and the dependent variable were the degree of knowledge achivement, nursing skill achivement, competence on practicing intramuscular injection skill and satisfaction about the learning method. Data was analyzed using descriptive statistics, chi-square test, t-test and Pearson's correlation coefficient with SPSS-PC program. The results were summarized as follows ; 1. There was statistically significant difference between the experimental group and control group in knowledge achievement about intramuscular injections (t=4.721, P=.000). 2. There was statistically significant difference between the experimental group and control group in nursing skill achievement(t=3.542, P=.001). 3. There was no statistically significant difference between the experimental group and control group in competence on practicing intramuscular injection skill (t=.627, P=.533). 4. There was statistically significant difference between the experimental group and control group in satisfaction about learning method(t=4.708, P=.000). 5. There was significant correlation between nursing skill achievement and knowledge achievement(r=.233, p<.05). In conclusion, this study suggests that videotaped-record learning method is an effective learning method for achieving intramuscular injection skill as a basic nursing skills. Therefore, further study with more developed research design and other fundamental nursing skill practice will be needed to investigate the effectiveness of videotaped-recored learning method.

Background: Transdermal fentanyl patch (TDFP) is a simple, noninvasive analgesic with continuous effect. The aim of this study was to evaluate the postoperative analgesic effect of TDFP. Methods: Sixty healthy patients undergoing cesarean section were divided into 3 groups. Postoperative pain was controlled with different methods; Group I: application of TDFP-$25{\mu}g/hr$, Group II: intramuscular injection of ketoprofen; Group III: continuous epidural block. Pain scores (numerical rating scale, NRS), number of patients who needed additive ketoprofen injections and side effects were recorded at 8, 20, 32, 44 hours postoperatively. Results: There was no significanant difference in pain score between Group I and Group II. The numbers of patients who need additive ketoprofen injections were lower in group I than group II. Pruritis (25%), nausea/vomiting (10%), leg numbness (40%) was experienced in group III, but not in Group I & II. Conclusions: TDFP-$25{\mu}g/hr$ for postoperative pain control is simpler and more convinient than intramuscular injection of analgesics.

PURPOSE. The purpose of this study was to assess the effect of systemically administered oxytocin (OT) on the implant-bone interface by using histomorphometric analysis and the removal torque test. MATERIALS AND METHODS. A total of 10 adult, New Zealand white, female rabbits were used in this experiment. We placed 2 implants (CSM; CSM Implant, Daegu, South Korea) in each distal femoral metaphysis on both the right and left sides; the implants on both sides were placed 10 mm apart. In each rabbit, 1 implant was prepared for histomorphometric analysis and the other 3 were prepared for the removal torque test (RT). The animals received intramuscular injections of either saline (control group; 0.15 M NaCl) or OT (experimental group; $200{\mu}g/rabbit$). The injections were initiated on Day 3 following the implant surgery and were continued for 4 subsequent weeks; the injections were administered twice per day (at a 12-h interval), for 2 days per week. RESULTS. While no statistically significant difference was observed between the two groups (P=.787), the control group had stronger removal torque values. The serum OT concentration (ELISA value) was higher in the OT-treated group, although no statistically significant difference was found. Further, the histomorphometric parameter (bone-to-implant contact [BIC], inter-thread bone, and peri-implant bone) values were higher in the experimental group, but the differences were not significant. CONCLUSION. We postulate that OT supplementation via intramuscular injection weakly contributes to the bone response at the implant-bone interface in rabbits. Therefore, higher concentrations or more frequent administration of OT may be required for a greater bone response to the implant. Further studies analyzing these aspects are needed.

Nicolau syndrome is a rare adverse reaction at the site of an intramuscular injection, and is characterized by severe pain immediately after the injection and rapid development of distinct skin lesions. As this syndrome is rare, it may be overlooked at the early clinical phase and subsequently, clinical outcomes may be worse due to delay in treatment. We report on a female who developed Nicolau syndrome following intramuscular diclofenac injection, which required surgical reconstruction. Understanding the characteristics of Nicolau syndrome and careful surveillance for relevant clinical features may help physicians to more quickly diagnose and treat this condition.

The anxiety and stress of nursing students on performance intramuscular injection diminished nursing skill performance. The purpose of this study was to identify the effects of the guided imagery program on anxiety, stress and nursing skill performance of nursing students. Method: The study design was time series with a nonequivalent control group pretest- posttest study. The Data were collected from the 30th of Oct. to the 6th of Nov. 2001. The objects of this study were 36 sophomores of university(18 for the experimental group, 18 for the control group). The Instruments used in this study were State Trait Anxiety Inventory developed by Spielberger (1972), Visual Analogue Scale for Stress and Nursing skill performance developed by the researcher. The guided imagery was provided through audiotapes to the subjects for 8 minutes. The pretest was given before the therapy to measure variables for both groups and the posttests were performed after intervention. The data were analyzed by the SAS program using t-test and paired t-test. Result: The results of this study are as follows. The level of anxiety of students who received the guided imagery were significantly lower than that of control group. the level of stress had a deeling tendency and the nursing skill performance level was significantly higher than that of control group. Conclusion: The guided imagery suggested as an effective nursing intervention did reduce the anxiety and promoted nursing skill performance of nursing students.

The pathogenecity of atypical Aeromonas salmonicida was studied in healthy Oreochromis niloticus. Inoculum at concentration of $1.5{\times}10^8CFU/ml$ and $3{\times}10^8CFU/ml$ was injected into healthy fish through intramuscular and intraperitoneal injections. Experimentally infected Oreochromis niloticus showed ulceration at the dorsal musculature and trunk region in addition to black coloration, congested gills, exophthalmia, and ocular hemorrhage. Congested liver and kidney were recorded in post-mortem examination. Mortality of the experimentally infected Oreochromis niloticus reached 100% after intramuscular injection at concentration of $3{\times}10^8CFU/ml$. Histopathological investigation of infected organs was also performed. There was a focal area of bundles of skeletal musculature showing hyalinization. In addition, hyperplasia, congestion, and fusion were noticed in the gill lamellae. There was also congestion in the blood vessels in the ocular chamber. Severe congestion was also noticed in the central vein of liver associated with focal aggregation of the melanin pigmented cells in the parenchyma. Degenerative changes were noticed in the epithelial cells lining of kidney tubules. Plant extracts carvacrol and its biological precursor cymene were found to be effective in treating experimentally infected Oreochromis niloticus at concentration of 100 or 200 ppm.

Background: Sciatic nerve injury due to intramuscular injection (SNIII) is still a health problem. This study aimed to determine whether there is a correlation between neuropathic pain and electrodiagnostic findings in SNIII. Methods: Patients whose clinical and electrodiagnostic findings were compatible with SNIII participated in this retrospective cohort study. Compound muscle action potential (CMAP) and sensory nerve action potential (SNAP) amplitudes of the sural, superficial peroneal, peroneal, and tibial nerves were graded from 1 to 4. Leeds assessment of neuropathic symptoms and signs scale (LANSS) was applied to all patients. Results: Forty-eight patients were included in the study, 67% of whom had a LANSS score ≥ 12. Sural SNAP amplitude abnormalities were present in 8 (50%) out of 16 patients with a LANSS score < 12, and 28 (87.5%) out of 32 patients with a LANSS score ≥ 12, with significant differences between the groups (P = 0.011). There was a positive correlation between the LANSS score and the sural SNAP amplitude grading (P = 0.001, r = 0.476). A similar positive correlation was also found in the LANSS score and the tibial nerve CMAP amplitude grading (P = 0.004, r = 0.410). Conclusions: This study showed a positive correlation between the severity of tibial nerve CMAP/sural SNAP amplitude abnormality and LANSS score in SNIII. Neuropathic pain may be more common in SNIII patients with sural nerve SNAP amplitude abnormality.

Background To achieve improvements in intramuscular injection, autologous fat grafting, and gluteal artery perforator flaps in infants and children, the relationships of computed tomography (CT)-determined gluteal muscle thickness (MT) and subcutaneous tissue thickness (SCT) with age and body mass index (BMI) were analyzed. Methods Gluteal SCT and MT at ventrogluteal (VG) and dorsogluteal (DG) sites were measured in a standardized manner in 350 patients aged 0 to 6 years who had visited a tertiary hospital and had undergone abdominopelvic CT between January 2005 and December 2016. Recorded measurements were analyzed using one-way analysis of variance and stepwise multiple regression to identify the factors that were most closely related to MT and SCT. Results Subcutaneous tissue at VG sites was thinner than at DG sites, but not significantly so in any age group. Muscles tended to be thinner at VG sites in 4 to 7-year-old, but thicker at VG sites in 1 to 3-year-old, though the differences were not significant. MT in the VG and DG regions was found to be related to age, and SCT in these regions to be related to age and BMI. Conclusions The VG and DG sites should be considered as alternatives for intramuscular injection in infants and children when the anterolateral site is problematic. In addition, considering the gluteal MT and SCT of infants and children should help produce good results in autologous fat grafting and gluteal artery perforator flap harvesting.
