A 24 year-old man attempted suicide by injection of 1 cc of thinner into his left antecubital vein; 3 hours later, he visited our emergency room because of left chest pain. We suspected a chemical pneumonitis based on the abnormal findings of his chest X-ray and computed tomography. On the 3rd day after admission, a cellulitis also occurred at the injection area. His symptoms were relieved after supportive care for 2 weeks. There is significant experience with intoxication of thinner inhalation, whereas intoxication of intravenous thinner is rare.

We report an unusual case of respiratory depression and prolonged apnea after the second dose of 100-mg intravenous tramadol. Due to continuous pain at foley catheter keep site, intravenous tramadol was administered to the patient. Soon after the second dose of tramadol injection, the patient became apneic. The patient did not respond to verbal command and started exhibiting oxygen desaturation. The patient was quickly treated with 100% oxygen, and it took 4 hours for the spontaneous respiration to return to regular. This case report demonstrates that even two doses of tramadol administered intravenously may manifest as sudden and prolonged apnea. Respiratory depression with tramadol has been reported in patients with impaired renal functions and Cytochrome P(CYP) 2D6 gene duplication.

Objectives : To study the effect of SB injection on tumor size in an advanced non-small cell lung cancer patient. Methods : A patient was clinically diagnosed as advanced non-small cell lung cancer (Stage IIIa). Four cycles of intravenous SB injection were conducted. Each cycle lasted 4 days. The content of 7vials SB was injected every day. To compare the tumor size before treatment and after four cycles of SB injection, chest computed tomography (CT) was performed. Results : Follow-up CT images showed that the tumor size was reduced. In admission, size of the tumor $6.7{\times}8.5{\times}9.5cm$ on the left lower lobe of lung. After SB injection, size of the tumor $5.6{\times}6.8{\times}8.4cm$ by Chest CT. The patient's symptoms such as cough, sputum were improving until four cycles of SB injection. Numerical rating scale (NRS) showed improvement of Chest pain from point 3 to point 0. Conclusions : This case study suggests that intravenous SB injection may have significant effects of anti-tumor for non-small cell lung cancer.

Background: The incidence of pain on injection of propofol varies between 30 and 100%. A variety of pretreatments have been tried to alleviate this problem such as a local anesthetics, cooling and opioids. However, none of these pharmacological maneuvers were satisfactory yet. In a recent study, subhypnotic doses of both thiopental sodium and propofol decrease the acute pain. We report a comparison of thiopental sodium, lidocaine and placebo on the incidence and severity of pain on injection of propofol. Method: A controlled, double-blind study was performed to compare the prior administration of intravenous saline 2 ml(n=30, group S), lidocaine 20 mg(n=30, group L) and thiopental sodium 50 mg(n=30, group T) in alleviating the pain by propofol. Injection pain was assessed with the four-point verbal categorical scoring system. Result: The incidence of injection pain during induction was lower in group L(30%) and T(17%) than group S(77%). The incidence of injection pain was lower in group T(17%) than group L(30%), but not significant statistically. The pain scores for recall of pain in the recovery room was simlar to those pain during propofol induction. Conclusion: The pretreatment of thiopental sodium can be effective in reducing both incidence and severity of propofol injection pain and has similar effect to lidocaine to prevent propofol injection pain.

본 연구의 목적은 시뮬레이션 기반 정맥주사 교육의 효과를 시뮬레이션 매체별로 비교 분석하고 대상자 만족도를 평가함으로써 시뮬레이션 기반 교육이 간호학생의 임상실무수행능력과 수행 자신감을 향상시킴과 동시에 대상자 만족도를 높이는데 도움이 되는 교육 방법임을 검증하는 것이다. 본 연구에서는 간호학과 2학년생 90명을 무작위로 동영상군에 31명, 모형군에 28명, 컴퓨터시스템군에 31명을 배정하였다. 동영상군은 기본간호학회에서 개발한 교육용비디오를, 모형군은 정맥주사모형을, 컴퓨터시스템군은 컴퓨터로 작동되는 정맥주사용 교육프로그램을 이용하여 1회 교육과 5회 실습을 실시한 후 대상자들끼리 짝을 이루어 손등 부위에 정맥주사를 시행하였다. 간호학생의 임상수행능력을 정맥주사 성공률로 분석한 결과, 동영상군 16.1%, 모형군 64.3%, 컴퓨터시스템군 38.7%가 성공한 것으로 나타났으며 세 군간에 유의한 차이가 있었다. 수행 자신감은 정맥 주사 전, 후 모두 세 군간에 유의한 차이가 없었으나 정맥주사 성공여부에 따른 차이를 비교한 결과, 정맥 주사 전, 후에 모두 유의한 차이가 있었다. 대상자 만족도는 세 군간에는 유의한 차이가 없었으나 정맥주사 성공여부에 따라서는 유의한 차이가 있었다. 이상의 연구결과에서 정맥주사 기술은 동영상과 컴퓨터시스템보다 모형을 이용한 시뮬레이션 기반 교육이 간호학생의 임상실무 능력을 향상시키는데 기여한 것으로 나타났으며 정맥주사에 성공한 학생이 성공하지 못한 학생보다 수행 자신감이 더 높은 것으로 나타났다. 그러나 이는 한 가지 간호 기술과 관련된 결과로 추후 다양한 간호기술에 적합한 시뮬레이션 교육매체를 평가하는 연구가 필요하다.

Advanced age is one of the risk factors for vascular diseases that are mainly caused by impaired nitric oxide (NO) production. It has been demonstrated that endothelial arginase constrains the activity of endothelial nitric oxide synthase (eNOS) and limits NO generation. Hence, arginase inhibition is suggested to be vasoprotective in aging. In this study, we examined the effects of intravenous injection of Piceatannol, an arginase inhibitor, on aged mice. Our results show that Piceatannol administration reduced the blood pressure in aged mice by inhibiting arginase activity, which was associated with NO production and reactive oxygen species generation. In addition, Piceatannol administration recovered $Ca^{2+}$/calmodulin-dependent protein kinase II phosphorylation, eNOS phosphorylation and eNOS dimer stability in the aged mice. The improved NO signaling was shown to be effective in attenuating the phenylephrine-dependent contractile response and in enhancing the acetylcholine-dependent vasorelaxation response in aortic rings from the aged mice. These data suggest Piceatannol as a potential treatment for vascular disease.

Purpose: The purpose of this study was to compare the effectiveness of training using an intravenous (IV) arm model versus a computer simulator for IV injections. Method: Study was a quasi-experimental study conducted with 106 nursing students. Participants were divided into two groups: the IV Arm Group using a mannequin arm model (control group) and the Computer Simulator Group using the Virtual IV demonstration (experimental group). Theoretical lectures and video presentations on IV injections were given to both groups. Each group went through the training practice using the IV arm or computer simulator. After the completion of training, questionnaires were given to the students to evaluate their learning attitudes and experiences, self-confidence in IV injection, and satisfaction with the training materials. Results: Student satisfaction with the training materials including the reality, usefulness, and educational effects showed notable differences between the two groups with the Computer Simulator group reporting more positive effects that the IV Arm group. However, there was no statistical difference between the two groups in the categories of learning attitude, learning experience, or self-confidence. Conclusion: While there was a differences in strengths and weaknesses of the two methods, both methods should be considered for practice and further study needs to be done on educational effectiveness.

The effects of morphine HCl on the mesenteric mast cells were studied the electron microscopy. The results of the observations are as follows: 1. In the experimental group for intravenous injection of morphine HCl 12 mg/kg, the granules appeared cluster, granular lysis and an electron transparent appearance. Frequently, some granules appeared in the extracellular space. 2. In the experimental group for intravenous injection of morphine HCl 24 mg / kg, it was observed. that the formation of a clear halo or a space around each granule. Many altered granules showing a reticular texture (type 2) are observed in the cytoplasm. 3. From the results mentioned above, it is suggested that rat mesenteric mast cell' granules were affected by morphine HCl.

This study compared the blood-brain barrier permeability of [$^3H$] taurine in senescence-accelerated mouse (SAM) and normal mouse with common carotid artery perfusion (CCAP) method and intravenous injection technique to establish a possible relation between aging and changes in tissue levels of taurine. The SAM strains show senescence acceleration and age-associated pathological phenotypes similar to geriatric disorders seen in humans. In the result of this experiments, the plasma clearance of [$^3H$]taurine in SAM was almost comparable with that of normal mice by intravenous injection technique, but the brain volume of distribution ($V_{D brain}$) of [$^3H$]taurine in SAM by CCAP method reduced by 85% compared with that in normal mice. These results suggest that aging may have an effect on the brain transport activity of taurine in disease state model animal.
