No definitive etiology or risk factors have been identified that predispose individuals to developing complex regional pain syndrome (CRPS). We experienced two cases of CRPS developed after arterial and venous puncture which were done in regular medical work. A 35-years old female patient was suffered from pain and allodynia with swelling at right hand and wrist after radial artery puncture for monitoring of blood pressure during general anesthesia. A 24-years old male patient had pain and swelling with allodynia at the right fingers and arm after median cubital vein puncture for blood sampling. They did not have proper pain management as CRPS patients in the past weeks and months after their pain occurred. They were diagnosed as CRPS and started undergoing various interventional procedures, which led to improve their pain condition. Our cases suggest that CRPS could develop without any proved tissue damage in routine medical practice. In conclusion, health care workers should be educated in knowledge about the uncommon medical condition and proper consultation to pain specialist when it happens.

경추간판탈출증 환자에서 척수조술을 위해 요추천자를 시행한 후에 갑자기 양하지마비가 발생한 1례를 보고 한다. 척추종괴환자에서 요추천자후 합병증으로 나타나는 운동마비는 요추천자후 1~4일째에 서서히 오는 경우가 일반적이며, 수시간내에 급성으로 하지마비를 나타내는 경우는 매우 드물어 현재까지 6례 정도만 보고되고 있을뿐이며 그 원인질환은 대부분 척수종양이다. 경추간판탈출증 환자에서 척수조술을 위해 요추천자를 시행한 후에 갑자기 양하지마비가 발생한 임상보고례는 현재까지 없다. 이러한 합병증을 막기위해서는 척수장애증상을 보이는 경추간판탈출증 환자에게 척수조술대신에 자기공명촬을 시행함이 현명하리라 본다. 이러한 합병증이 올 수 있는 기전과 예방방법에 대해 고찰하다.

The Epidural blood patch is considered the gold standard for managing postdural puncture headache when supportive measures fail. However, it is a procedure which can lead to another inadvertent dural puncture. Other potential adverse events that could occur during a blood patch are meningitis, neurological deficits, and unconsciousness. The bilateral greater occipital nerve block has been used for treating chronic headaches in patients with PDPH with a single injection. This minimally invasive, simple procedure can be considered for patients early, along with other supportive treatment, and an epidural blood patch can be avoided.

Purpose: The purpose of this study was to examine the puncture incidence of surgical gloves in an operational setting. Methods: The 277 surgical gloves were used collecting at one general hospital located in Seoul from February 1, 2011 to April 3. The data were analyzed by $x^2$ test, Fisher's exact test, and multiple logistic regression. Results: In the dental and orthopedic department, the puncture incidence were significantly higher than others. The time of wearing gloves demonstrated significant difference: The group 181-240 minutes had a significantly higher than those with under 90, 91-180, or over 240 minutes. The influencing factors were as follows. Compared to that of the 2nd assistants, the puncture incidence rates of the surgeons were 9.91 times, scrub nurses were 8.39 times higher respectively. The participants in work experience under 1 year showed a 4.58 times higher than those with over 7 years. In addition, compared to the puncture incidence rate of neurosurgery department, the 17.41 times in cardio-thoracic surgery, 13.89 times in dental surgery, 4.93 times in gynecology, and 4.97 times in orthopedics higher respectively. Conclusion: There is a need for training operational room personnels to occasionally exchange the gloves even during the procedure and to use double surgical gloves.

Objective : To develop a simple, reproducible model of disc degeneration in rabbits through percutaneous annular puncture and to confirm the degree of degeneration over time. Methods : Fifteen New Zealand white rabbits (4 to 5 months old and weighing approximately 3 to 3.5 kg each) underwent annular puncture of the L2-L3, L3-L4, and L4-L5 discs. Rabbits were sacrificed at 4, 8, or 20 weeks after puncture. For a longitudinal study to assess changes in disc height over time, serial X-rays were performed at 0, 2, 4, 8, and 20 weeks for rabbits in the 20-week group. Upon sacrifice, the whole spinal column and discs were extracted and analyzed with magnetic resonance imaging (MRI), real time reverse transcriptase-polymerase chain reaction, and histological staining. Results : The X-rays showed a slow, progressive decrease in disc height over time. Significant disc space narrowing compared to preoperative disc height was observed during the time period (p<0.001). The MRI grade, aggrecan, and matrix metalloprotease-13 mRNA expression and hematoxylin and eosin/safranin O/anti-collagen II staining were consistently indicative of degeneration, supporting the results of the X-ray data. Conclusion : Percutaneous annular puncture resulted in slow, reproducible disc degeneration that was confirmed by radiology, biochemistry, and histology. This in vivo model can be used to study and evaluate the safety and efficacy of biologic treatments for degenerative disc disease.

Purpose: This study was conducted to examine the effects of ethyl chloride spray during arteriovenous fistula puncture on pain, depression, and noncompliance in hemodialysis patients. Methods: This study used a randomized controlled trial design on adults with chronic renal failure who received hemodialysis treatment through arteriovenous fistula. Ethyl chloride spray was applied to 20 subjects in the experimental group during arteriovenous fistula puncture, and a placebo spray was applied to 20 subjects in the control group; the intervention was conducted 12 times for 4 weeks. A total of 33 participants were used in the final analysis. The outcomes were measured using the face pain rating scale, Center for Epidemiological Studies Depression Scale (CES-D), and modified United States Renal Data System tools. Results: As a result of the pre-homogeneity test between the two groups, it was confirmed that the sexes were not homogeneous. Therefore, sex was treated as a covariate and analyzed. Puncture pain was significantly reduced in the experimental group (p<.001). However there was no significant difference between the groups in depression and noncompliance. Conclusion: Ethyl chloride spray was convenient and effective pain management intervention for both hemodialysis patients and medical staff.

High-ester pectin을 HCI 단독 또는 HCI 과 $NH_4OH$를 병용하여 demethylation 시킨뒤 얻어진 low-ester pectin(LM pectin)으로 gel을 제조하였다. LM pectin gel의 단단함과 강도(强度)를 측정한 결과 HCI로 처리된 LM pectin gel은 일반적으로 강도(强度)가 약하고 거칠며 탄력이 없었다. 반면 $HCl-NH_4OH$로 처리한 LM pectin gel은 텍스쳐가 부드럽고 탄력이 좋았다. 물리적 성질에 대한 LM pectin의 화학적 조성의 상관 관계에서 단단함(Sag값)에 대한 ester함량 및 분자량, 그리고 강도(强度)(puncture stress)에 대한 amide 및 ester함량 EH는 분자량 간에는 유의성 있는 관계가 밝혀졌다. 상관성이 높은 화학적 인자에서 LM pectin gel의 물리적 성질을 예측할 수 있는 관계식을 산출하였다.

Holstein cow ovaries obtained at a slaughterhouse were used to study the influence of the oocyte collection methods (slicing, puncture, aspiration I and II) on recovery efficiency and subsequent in vitro maturation and embryonic development competence of immature oocytes recovered. In the slicing method, the whole ovarian was chopped into small pieces with a surgical blade. In the puncture method, the whole ovarian surface was punctured by 18-g needle. In other 2 aspiration methods, collected oocytes by aspirating from the visible follicles using an 18-g needle attached to a 5 ml syringe (aspiration I) or using a constant negetive pressure (-80 mmHg) with a vacuum pump (aspiration II). The oocytes were classified into 4 classes on the basis of the morphology of cumulus cells and cytoplasmic appearance of oocyte. Slicing ($9.6{\pm}0.4$) and puncture ($9.7{\pm}0.4$)yielded a larger number of oocytes per ovary than other two aspiration methods (aspiration I and II were $5.8{\pm}0.3$and $5.6{\pm}0.4$, respectively) (p<0.05). The number of the highest quality oocytes (grade A) per ovary was significantly higher in slicing ($4.2{\pm}0.2$) and puncture ($4.6{\pm}0.1$) methods than in other methods (aspiration I and II were $1.2{\pm}0.2$ and $1.4{\pm}0.2$, respectively) (p<0.05). The rate of nuclear maturation of the highest and higher quality oocytes (grade A and grade B, respectively) was not affected by the oocytes collection methods. The oocytes collection methods also did not influence subsequent embryonic developmental competence after in vitro fertilization with M II stage oocytes. It is concluded that slicing and puncture methods of the ovaries can be used as an alternative techniques to aspiration by the syringe or vacuum pump.

동결이 두류의 cooking time, 맛 그리고 미세구조에 미치는 영향을 검토하였다. 검정콩과 대두를 충분히 수화시킨 후 동결하여 $100^{\circ}C$의 물에서 가열하였을 때 cooking time은 각각 10분과 20분으로서 동결하지 않은 두류에 비하여 cooking time이 1/2로 단축되었다. 관능시험의 결과 동결한 두류는 동결하지 않은 두류에 비하여 텍스쳐, 향미 및 전체적 선호성이 우수하였다. 또한 회귀분석의 결과로 얻은 관능점사에 의한 텍스쳐와 Instron으로 측정한 puncture force간의 상관관계식을 이용하여 puncture force로써 관능적 텍스쳐를 판정할 수 있었다. 또한 두류의 동결시에 일어나는 미세구조의 변화를 검토한 결과 동결에 의한 세포벽의 손상은 없었으나 cooking 후 단백립을 싸고 있는 지방구의 배열이 파괴됨이 관찰되었다. 따라서 동결은 단백립을 싸고 있는 지방구의 배열을 파괴함으로써 열수가 쉽게 침투되어 cooking을 용이하게 하는 것으로 추정되었다.
