  • This experiment has investigated the influence of Yamen (Du. 15) point injection on learning and memory dysfunction caused by cerebral ischemia and reprofusion in bilateral cervical general artery combined with bleeding on mouse tail to mimic vascular dementia in human beings. By dividing 40 mice into 4 groups (group1false operation group, group2model group, group3point injection with Cerebrolysin group4point injection with saline.) According to random dividing principles, we observed the influence of Yamen(Du. 15) point injection on the time of swimming the whole course used by model mice which had received treatment for different days in different groups, and the influence of those mice on wrong times they entered blind end. The result showed that point injection with Cerebrolysin and saline could improve learning and memory dysfunction of the mice caused by cerebral ischemia.

  • A multi-cavity injection mold system of protein chip for point-of-care with cavity temperature and pressure sensors was proposed in this work. In advance of manufacturing for the multi-cavity injection mold system, a single cavity injection mold system to mold protein chip was considered. Injection molding analysis for the presented system was performed to optimize the process of the molding and suggest guides to design. On the basis of the results for the single cavity system, a multi-cavity injection mold system for protein chip was analyzed, designed and manufactured with cavity temperature and pressure sensors. Results of balanced filling for protein chip models were obtained from the presented mold system.

  • We theoretically studied synchronization of chaotic oscillation in semiconductor lasers with chaotic light injection feed-back induced chaotic light generated from a master semiconductor laser was injected into a solitary slave semiconductor laser. The slave laser subsequently exhibited synchronized chaotic output for a wide parameter range with strong injection and frequency detuning within the injection locking scheme. We also analytically examined chaos synchronization based on a linear stability analysis from the view point of synchronization based on a linear stability analysis from the view point of modulation response of injection locked semiconductor lasers to chaotic light signal.

  • Headache is a common disease of the general population. But the main problem in any study of headache has been that of defining the disease entities. In 1988, the Headache Classification committee of the International Headache Society introduced operational diagnostic criteria for all headache disorders into 13 major group; migraine, tension-type headache, cluster headache and chronic paroxysmal hemicrania etc. Sjaastad was the first to describe "cervicogenic headache", one of various head pain syndromes that probably originate in the cervical spine. Between March 1995 and June 1995, we studied 78 out-patients of the Department of Neuro pain clinic, Sanggye Paik Hospital, Inje university. We divided the patients into three study group: Fifty-three patients with tension-type headache, 13 with cervicogenic headache, and 12 with migraine headache. The reponse of trigger point injection and $C_2$-ganglion block in patients was investigated. We paid particular attention to the response of trigger point injection in patients of the three group. The effect of trigger point injection was more marked in tension-type headache group than in the other categories. The pain reduction after $C_2$-ganglion block was more marked in cervicogenic headache group than in the others.

  • The shoulder is a complex area which makes it vulnerable to painful pathologic processes. Chronic shoulder pain has become more common recently due to increased use of computers and a ,generally more sedentary life style among most people . Trigger point injection and neural blockade are useful for the management of chronic shoulder pain which has not improved with conservative treatment. Published articles concerning trigger point injection or neural blockade for chronic shoulder pain were reviewed to evaluate promising methods. If we are careful to remain aware of the details and complications in addition to adhering to effective treatments, these should be good armamentarium for doctors enthusiastic about the management of chronic shoulder pain.

  • The trigger point injection technique is widely used in pain clinics for the treatment of acute and chronic pain. Yet it has a variety of complications such asvasovagal syncope, total spinal anesthesia, paralysis, root block, pneumothorax, needle breakage, skin infection, and hematoma formation. Among them, the simultaneous occurrence of psoas and epidural abscesses is extremely rare. We report here on a patient who was diagnosed with epidural and psoas abscesses after paravertebral trigger point injection.

  • Background: Despite tension type headache is popular, the exact mechanism and method of treatment are not certain yet. So, we supposed the basic mechanism of tension type headache is myogenic, and did Tienchu acupoint block, occipital nerve block, and trigger point injection in tension type headache patients. Methods: Fifty-seven tension type headache patients were treated with local anesthetics and small dose of steroid. The intensity of pain and effect of every treatment was evaluated as Verbal Rating Score (VRS; 0~10) before and after every treatment. Evaluation of treatment was based on the time of treatment (1,2 times, 3 times, 4,5 times). Goal of treatment was VRS reaching below two point and it was considered as treated state. Results: Symptom improvement rates of each treatment were 90% (1, 2 times), 91% (3 times), 70% (4, 5 times) respectively. VRS reduction more than 50% rates were 60%, 64%, 60% respectively. Treated state (VRS<2) rates were 33%, 27%, 30% respectively. Conclusion: Tienchu acupoint block, occipital nerve block, trigger point injection were sorts of most effective and simply applicable modalities of treatment in tension type headache.

  • Skeletal muscles which are the largest part of human body may develop pain and dysfunction. The myofascial pain syndrome that has trigger points as a unique characteristic is a major cause of morbidity. Trigger points are focal, hyperirritable painful areas located in a taut band of skeletal muscle. They produce local area pain and a referred pattern pain and often accompany chronic joint dysfunction. Various modalities are used to inactivate trigger points in myofascial pain syndrome. Trigger-point injection has been shown to be one of the most effective treatment modality to provide prompt relief of symptoms. This review article presents general concept of myofascial pain syndrome and technique of trigger point injection.

  • Frozen shoulder is known as a self-limited disease. But, its long duration and pain nature can make the patients debilitative. And most patients cannot tolerate a chronically painful extremity and are concerned about the possibility of developing permanent dysfunction. In painful phase of frozen shoulder, some aggressive mordalties as like trigger point injection or suprascapular nerve block can beneficial to: reduce discomfort and pain. In order to document clinical results, we evaluated the results of 134 frozen shoulders treated with trigger point injection and/or suprascapular nerve block at Kyungpook National University Hospital, from January 1995 to April 1997. The treatment group was divided into 3 modalities: 17 cases in trigger point injection(TPI), 39 cases in suprascapular nerve block(SSB), and 78 cases in both methods. The supportive treatment including oral medication, heat and stretching exercise was also applied. The average age at the time of diagnosis was 57 years old and average follow-up time was 18 months. The results were as follows: Average time of significant improvement in pain was 9 days. Eighty-eight percent (119 cases) was improved in pain and range of motion after injecllion treatments; 82%(14/17) with TPI, 85%(33/39) with SSB, and 92%(72/78) with both. Early improvement of paih within 1 week was 72% in the treatment-responsive group, in which TPI group has 100% response(14/14) and sse has 94% response(31/33)
