The purpose of this study was to compare the effect of the Z-track intramuscular injection technique with the effect of the stand and intramuscular injection technique on the severity of discomfort and leasions at the injection site. The subjects of the study were 20 patients with only early tuber culosis excluding another abnormalities (a akin rash, allergy to topical use of alcohol, jaundice, edema, neurosensory abnormality, coagulation defects, obesity and thin). Data collection was done from Feb. 1 to March 15, 1988 by means of Korean Pain Measurement Tool, Visual Analogue Scale, and Objective measures of injection site lesions. The results of this study were as follows ; 1) Hypothesis 1 ; “The severity of subject discomfort is less following administration of the Z-track intramuscular injection technique than following administra tion injection technique.” was not sopported 2) Hypothesis 2 ; “The degress of severity subject discomfort is less following administration of the Z-track intramuscular injection technique than following administra tion of the standard intramuscular injection technique.” was not supported. 3) Hypothesis 3 ; “The severity of injection site lesions is less following administra tion of the Z-track intramuscular injection technique than following administration of the standard intramuscular injection techniques.” was not supported. 4) The terms that were selected included factor II (mild-moderate pain) of Ratio Scale Measuring Pain using Korean Pain Terms. In conclusion ; it was found that there was not a difference from the severity of subject discomfort between two groups, but the degress of severity of subject discomfort about following administration of the Z-t-rack intramuscular injection was tended to be declined. Therefore further studies suggest that the Z-track intramuscular injection technique can decrease the severity of discomfort in persons receiving frequently intramuscular injections. First of all, it is necessery to be developed an effective tool of discomfort measurement for the intramuscular injection in Korean.

We present a method for the estimation of intramuscular electromyographic(EMG) signals from the given surface EMG signals. This method is based on representing the surface EMG signal as an autoregressive(AR) time model with a delayed intramuscular EMG signal as an input. The parameters of the time series model that transforms the intramuscular signal to the surface signal are identified. The identified model is then used in estimating the intramuscular signal from the surface signal.

Purpose: To determine the effects of neck and back touch on Ultrasonic Vocalization (UV) and the Rat Grimace Scale (RGS) in rats touched by the human hand as an intervention for reducing pain and anxiety associated with intramuscular injections. Methods: This study was a randomized, controlled, pre-test/post-test design study. Twenty male Sprague-Dawley rats were assigned to either the experimental or control groups (n= 10 rats/group). The experimental group was touched in a manner similar to massaging the rat's neck and back twice a day for one week. The two groups received two intramuscular injections. The 22kHz and 50kHz UV and the RGS scores were measured before and after each intramuscular injection. Results: The 22kHz UV and RGS score were significantly higher in the control group than in the experimental group when the first intramuscular injection was administered; whereas, no difference between the experimental and the control groups were observed when the second intramuscular injection was administered. There was no statistical difference in the 50kHz UV between the two groups when the first and second injections were administered. Conclusion: This study found that touching was an effective intervention method to reduce negative emotions and pain in rats receiving their first intramuscular injection.

The influence of three cooking methods (stewing, microwaving and Aluminium (Al) foil-baking) was evaluated on the content of intramuscular lipid and the composition of intramuscular fatty acids of Hyla rabbit. The percentage of intramuscular lipid in cooked-longissimus dorsi (LD) (dry weight %) were in the order mentioned below: microwaving > foil-baking > stewing. All treated samples showed decrease in the proportion of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA), whilst increase in the proportion of saturated (SFA) and n-6/n-3 value during processing. All of the cooked samples had the n-6/n-3 ratio within the recommended range (5-10). By the analysis of partial least squares regression (PLSR), the microwaving treatment was better to keep the stability of unsaturated fatty acids (UFA), whilst the long-time Al foil-baking did the most serious damage to UFA, especially the PUFA. In addition, the heating method showed greater influence on the samples than the processing time. The shorter processing time was better to retain the intramuscular PUFA of Hyla rabbit, especially the LC-PUFAs (C20-22). Considering all the factors, microwaving showed the superiority in reserving the composition of intramuscular fatty acids of Hyla rabbit.

The changes in fatty acid composition of total intramuscular lipid and phospholipids were investigated in the longissimus dorsi, left-hind leg muscle, and abdominal muscle of male Ira rabbits. Changes were monitored at 35, 45, 60, 75, and 90 d. Analysis using gas chromatography identified 21 types of fatty acids. Results showed that the intramuscular lipid increased and the intramuscular phospholipids (total intramuscular lipid %) decreased in all muscles with increasing age (p<0.05). An abundant amount of unsaturated fatty acids, especially polyunsaturated fatty acids, was distributed in male Ira rabbits at different ages and muscles. Palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), and arachidonic acid (C20:4) were the major fatty acids, which account to the dynamic changes of the n-6/n-3 value in Ira rabbit meat.

Background: Lipomas are benign soft tissue neoplasms of mature adipose tissue commonly occurring in the trunk or extremities. But, intraoral lipomas are rare entities which may be only noticed during routine dental examinations. Especially intramuscular lipomas on the tongue have been reported very rarely. In this study, we report a case of intramuscular lipoma on tongue, with a review of the literature from 1978 to 2019, providing data on age, gender, location, presenting symptoms, size, surgical methods, and recurrence. Case presentation: A case of intramuscular lipoma occurring in tongue region in a 65-year-old male is reported. Surgical excision is the mainstay of treatment for the lesion. In order to decrease the deformity and discomfort after the excision, we tried to modify surgical technique using enveloped mucosal flap. This technique provided more comfortable healing procedure on the operative site without recurrence. Conclusion: This is a rare case of large intramuscular lipoma on tongue. Surgical excision with enveloped mucosal flap design was performed to diminish postoperative raw surface and discomfort and a 24-month follow-up showed excellent healing without any recurrence. A case of intramuscular lipoma on tongue and relevant literature reviews are presented in this study.

This experiment was carried out to determine the contributions of acetate, glucose, amino acids and amino acid metabolites as carbon precursors for the incorporation of radioisotope, in intramuscular and subcutaneous adipose tissue and the effects of insulin on lipogenesis and adrenergic agent, norepinephrine on lipolysis in both tissues. The rate of incorporation of $C^{14}$ labelled acetate, glucose, leucine, isoleucine and ${\alpha}$-ketoisocaproic acid into adipose tissue has been measured in subcutaneous and intramuscular adipose tissues. The rate of incorporation was greater (p<0.05) from acetate than glucose in both subcutaneous and intramuscular adipose tissue and the rate of incorporation of carbon precursors into adipose tissues was greater in subcutaneous than in intramuscular adipose tissues. In comparison of amino acids, the rate was highest (p<0.05) with leucine followed by isoleucine and ${\alpha}$-ketoisocaproic acid in subcutaneous adipose tissue, in which there were no differences. Also, in intramuscular tissue, leucine was highest (p<0.05), and the rate of incorporation decreased in the same order. The rates of carbon precursor incorporation appeared to be higher in subcutaneous than in intramuscular tissue. For incorporation of radio-labelled acetate and glucose into intramuscular adipose tissue. preincubated for 48 hrs with insulin and IGF-1, insulin was the most effective to stimulate the incorporation of precursors in both substrates but there was no difference between insulin and IGF-1 in glucose incorporation. For glyceride-fatty acid synthesis, acetate was significantly (p<0.05) greater than glucose in both subcutaneous and intramuscular adipose tissue, and glyceride-glycerol synthesis was greater (p<0.05) for glucose than acetate in both adipose tissues. The rates of lipogenesis from both precursors were slightly greater in subcutaneous than intramuscular adipose tissue. There was significant (p<0.05) site effect in insulin treatment for glyceride-fatty acid synthesis. But there were no significance in control and norepinephrine. For glyceride-glycerol synthesis, there was no site effect caused by hormonal treatment. Insulin was the most effective (p<0.05) in glyceride fatty acid synthesis, while norepinephrine was the same as control. Compared with control, glyceride-glycerol synthesis from acetate in insulin treatment was significantly (p<0.05) low in subcutaneous, but high in intramuscular tissue. At the same time, in both tissues, it was lower in norepinephrine treatment than in control. Glyceride-glycerol synthesis from glucose was highest (p<0.05) in norepinephrine treatment followed by insulin although there was no significance between insulin and control. Lipolysis was not affected by insulin but was increased by norepinephrine when added to adipose tissue incubations in vitro. Rates of basal lipolysis were greater in subcutaneous adipose tissue than in intramuscular adipose tissue.

The local irritation studies of DA-3002, an authentic recombinant human growth hormone (rhGH), were carried out in rabbits after the following treatment ; application into the conjunctival sac of the eye (single), single subcutaneous and intramuscular injection, 7-day repeated subcutaneous and intramuscular injection. The results obtained were as follows. In the result of ocular irritation test, 0.16% solution of DA-3002 could be considered as a non-irritating material. In single subcutaneous and intramuscular irritation test, the irritancy of 0.16% DA-3002 solution was not so much different from that of saline. The local irritation of DA-3002 by 7-day repeated injection was negligible and similar to that of saline by both subcutaneous and intramuscular routes. These results suggest that DA-3002 has no irritating activity when injected through subcutaneous or intramuscular route for clinical practice as 0.16% solution.

Intramuscular lipomas are benign adipose tumors of the soft tissues that may resemble liposarcomas because of their size, deep location, and occasionally infiltrative growth. An awareness of their existence is fundamental to treating them correctly, and their differential diagnosis from liposarcoma is essential. Magnetic resonance imaging (MRI) is a useful diagnostic tool to differentiate benign adipose tumors from liposarcoma. Marginal excision and biopsy are required for the definite diagnosis and the treatment of symptomatic intramuscular lipomas. To the best of the authors' knowledge, this is the first report in South Korea regarding the treatment of an intramuscular giant lipoma of the ankle.
