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.

Background: This study was designed to compare the efficacy of DentalVibe against 2% lidocaine gel in reducing pain during the administration of local anesthetic injection in the adult population. Methods: This was a split-mouth open-label, randomized, controlled clinical study conducted in the Department of Oral and Maxillofacial Surgery of a dental institute. Fifty patients who were scheduled for bilateral dental extractions requiring an inferior alveolar nerve block were enrolled in the study. Site A (n = 50) was coated with 2% lidocaine gel followed by a local anesthetic injection, and DentalVibe with local anesthetic injection was used for Site B (n = 50). The primary outcome was pain, which was recorded immediately after the administration of anesthetic injection using the Visual Analogue Scale [VAS 0 - 10]. Results: The VAS pain scores ranged from 4 to 10 for site A and 0 to 6 for site B. Comparison between the two sites showed a statistically significant difference [Mann-Whitney U test value = 51.50, P < 0.001] favoring site B. Conclusion: This study showed that DentalVibe reduces pain during injection of local anesthesia compared to topical anesthetic gel.

Two trials were conducted in a commercial dairy farm on heifer synchronization with PGF$_2$ $\alpha$. Animals showing estrus following the first injection were bred and animals not showing estrus were given the second injection 10 days later. In the first trial, the injection sites were rump and rump. In the second trial, the injection sites were rump and shoulder. Estrous detection was peformed 24 h after injection. Animals were bred by the same technician. In the first trial, the response rate for the first injection was 51.4% and the subsequent pregnancy rate of these animals was 60.0%. The response rate in the second injection was 57.1% and the pregnancy rate was 50.0%. In the second trial, the response rate in the first injection on the rump was 48.7% and the subsequent pregnancy rate was 70.6%. The second injection was given on the shoulder and the response rate was 60.0% and the subsequent pregnancy rate was 25.0%. The data suggests that the site of PGF2 $\alpha$ administration was critical to achieve success in estrous synchronization and pregnancy rates.

The vaccination for foot-and-mouth disease (FMD) is an effective way to control FMD. However, the injection of FMD vaccine causes abnormalities in pork meat by the incidence of lesions at the injection site. This study was conducted to investigate the inhibition effects of dietary bromelain, a natural protease derived from pineapple stems, on the incidence of lesions at the vaccination site on pigs. A total of 335 pigs (LYD [Landrace ${\times}$ Yorkshire ${\times}$ Duroc]; 7-week-old) were randomly allotted to two dietary treatments: control (basic diet) and bromelain treatment (diet supplemented with bromelain 1 kg/ton). The injection of FMD vaccine was conducted on 56- and 84-day-old pigs. Pigs with the bromelain treatment were fed a diet supplemented with bromelain for 14 days from 5 days before the vaccine injection. After slaughtering the pigs, the number of carcasses that had abnormal meat at the injection site of the vaccine and the amount of abnormal meat, discarded meat, and trimmings were recorded. Pork from the bromelain treated pigs had a lower incidence of abnormal meat caused by vaccine injection as well as a lower amount of abnormal meat, discarded meat, and trimmings than those of the control (p < 0.05). Our result suggests that dietary bromelain could improve the quality of pork meat by inhibiting incidence of lesions at the vaccine injection site.

Bordetella bronchiseptica and Pasteurella multocida are two main pathogens responsible for atrophic rhinitis (AR), which causes considerable economic losses in swine industry worldwide. Commercial vaccine has been widely used to prevent the damage from AR in Korea. Adverse effects of vaccination at the injection site have been reported, which results in the numerous complaint from farms. However, data on about local reaction at the injection site remains limited. In this study, we compared the local adverse effects of three commercial vaccines following intramuscular injection. The results showed that no gross lesion was founded at the injection sites of all three vaccines. In histopathologic examination, a various level of lesions was identified. Especially, the local reaction of vaccine including saponin as an adjuvant showed the lowest level of histopathological lesions, when compared to those of oil-based and vitamin E-based vaccines. Therefore, this study would provide the information about the extent of local reaction at the injection site and help the farmer to select AR vaccine in order to avoid adverse reaction due to vaccination.

일반적으로 구제역 백신 접종은 유침주사기를 사용하고 있다. 유침주사기 사용 시 근육 조직 및 림프구에 병변이 생기는 이상육이 발생하고 이는 소비자의 불만제기와 국내산 돼지고기(한돈)의 이미지 악화와 관련된다. 그 대안으로 무침주사기 개발이 이루어지고 있다. 본 연구는 무침주사기를 이용한 구제역 백신 접종 시 이상육 발생빈도를 조사하여 무침주사기의 활용성을 검증하기 위해 실시했다. 실험결과 무침주사기 사용 시 이상육의 발생이 유침주사기 사용 대비 유의적으로 낮았다(36 vs. 16%, p < 0.05). 따라서 무침주사기를 이용한 구제역 백신 접종 시 이상육 발생을 낮춰 돈육 품질을 높이고 소비자 불만을 감소시킬 수 있을 것으로 판단된다. 추가 연구로 무침주사기의 항체형성률, 작업효율성, 경제적 비용 등을 조사하고 무침주사기의 활용성을 검증할 필요가 있다.

Foot-and-mouth disease (FMD) is an infectious disease affecting pigs. The control of FMD in swine husbandry is very important because its outbreak results in a vast economic loss. FMD vaccination has effectively controlled FMD; however, it results in economic loss associated with the incidence of lesions in the pork meat at the injection site. The objective of this study was to investigate the effects of transdermal needle-free injection (NFI) of the FMD vaccine on the incidence of lesions at the injection site. Pigs (n=493) in the control group were vaccinated with the FMD vaccine using a commercial syringe needle, while 492 pigs in the transdermal NFI group received the FMD vaccine using a needle-free gas-powered jet injector. After the slaughter of the pigs, the incidence of lesions at the injection site of all pigs was checked by plant workers. The result of this study showed that the incidence of lesions in the pork ham from pigs vaccinated with NFI was 14.82% lower than that in control pigs (p<0.01). In addition, lesions generated in the NFI group were found just in the subcutaneous tissue. Therefore, the incidence of lesions at the injection site in pork from pigs vaccinated with the FMD vaccine can be effectively reduced by using transdermal NFI rather than a conventional syringe needle.

In this study we have investigated the pharmacokinetics and tissue distribution of GX-12, a multiple plasmid DNA vaccine for the treatment of HIV-1 infection. Plasmid DNA was rapidly degraded in blood with a half-life of 1.34 min and was no longer detectable at 90 min after intravenous injection in mice. After intramuscular injection, plasmid DNA concentration in the injection site rapidly declined to less than 1 ％ of the initial concentration by 90 min post-injection. However, sub-picogram levels (per mg tissue) were occasionally detected for several days after injection. The relative proportions of the individual plasm ids of GX-12 remained relatively constant at the injection site until 90 min post-injection. The concentration of plasmid DNA in tissues other than the injection site peaked at 90 min post-injection and decreased to undetectable levels at 8 h post-injection. The rapid in vivo degradation of GX-12 and absence of persistence in non-target tissues suggest that the risk of potential gene-related toxicities by GX-12 administration, such as expression in non-target tissues, insertional mutagenesis and germline transmission, is minimal.

The stability of ondansetron and fluconazole in 5% dextrose injection and normal saline during simulated Y-site injection at room temperature was studied. Ondansetron 0.03, 0.1 and 0.3 mg/ml were admixed 1:1 with fluconazole 2 mg/ml. The solutions were stored at room temperature and samples were retrieved at time 0, 1, 2, 4 and 12 hr for immediate assay. At the time of the assay and before any dilution, each sample was visually inspected for clarity, color, precipitation, and the pH was determined. Drug concentrations were measured by a stability-indicating high performance liquid chromatograph. Ondansetron 0.03, 0.1 and 0.3 mg/ml were stable when mixed with concentration of fluconazole 2 mg/ml. There were no change in clarity and color and no precipitates in any admixture for 12 hr of inspection. The pH measurements did not have a particular trend in any direction over time.
