A 48 year old man, has been suffering from a growing chondrosarcoma of sternum which has deeply invading the anterior mediastinum: He underwent wide resection of the chest wall tumor including a 4 cm free margin of normal tissue on all portions. The tumor as 15 × 16× 10cm in size arising from sternum and include both proximal one third of the clavicle and the 1 st, 2nd, and 3rd coital cartilages. The resected skeletal defect in the anterior wall was very large after wide resection of the'tumor and reconstructed due to paradoxical chest wall movement with sandwich like method of double over lapping Marlex mesh and methylmethacreylate, and steel wires. The soft tissue reconstructive procedure was dont with myocutaneous flap transposition use of pectoralis muscle. But the patient go infected with tuberculosis in the mediastinum two months after the operation. We had removed all of previously inserted prosthetics and performed curettage and drainage. Recently we experienced a case with giant chondrosarcoma of the sternum associated with tuberculous mediastinitis. The patient had an uneventful postoperative course and was discharged with adjuvant treatment such as antituberculous medication for 1 year.

A six-month old boy and a thirty-month old girl who suffered from dyspnea were admitted to our hospital. Their primary disease was congenital myopathy, and both of them had a history of recurrent pneumonia. Chest X-ray scan showed unilateral diaphragmatic eventration. To minimize the injury of weakened respiratory muscle in children with myopathy, VATS plication was performed under double lung ventilation. Each of the two patients were discharged on the 17th and 24th postoperative day. We report two cases of successful VATS plication in children with diaphragmatic eventration associated with congenital myopathy.

Background: Cold blood cardioplegic solution has been used to protect myocardium during open heart surgery with the hypothesis stating that it provides more oxygen supply to myocardium compared to crystalloid caridoplegic solution. We repeatedly infused cold blood cardioplegic solution to achieve myocardial protection. We biopsied a small portion of papillary muscle of patients with mitral valve replacement or double valve replacement during aortic cross-clamp time and evaluated the method of myocardial protection through the observation of changes in ultrastructure. We then analysed the relationship between changes in ultrasructure and peak postoperative CK-MB value and SGOT value. Material and method: We report observation on changes of myocardial ultrastructure, postoperative CK-MB and SGOT, and electrocardiogram in 31 patients who underwent cardiac operation. There were 11 males and 20 females, and they ranging in age from 28 to 69 years(mean score was 2.08$\pm$0.560, it was 2.37$\pm$0.558 at 40 minutes, and it was 2.36$\pm$0.523 at 70minutes. Mitochondrial score increased significant at 40 minutes. Mean value of postoperative peak CK-MB and SGOT were 37.3$\pm$17.061IU, 144.5$\pm$125.5IU respectively. We were not able to find any new Q were in EKG after the operation. There was no significant relationship between myocardium mitochondrial score and mean value of postoperative peak CK-MB and SGOT. Conclusion: In conclusion, with this study the cold blood cardioplegic solution was incomplete in preserving ultrastructure of myocardium even with satisfactory results in serum enzyme and EKG evaluation.

Calponin 3 is an F-actin-binding protein and plays a key role in regulating spine plasticity and synaptic activity in neurons. Unlike the other subtypes, calponin 1 and 2, which are expressed in smooth and cardiac muscle cells, calponin 3 is highly expressed in the brain. The goal of this study was to elucidate the spatiotemporal expression pattern of calponin 3 following repeated administration of 3-nitropropionic acid in mice. The repeated administration of 3-nitropropionic acid generated necrotic neuronal cell death in the striatum. Calponin 3 was up-regulated in the neuroprotective penimbral region from 1.5 days after the last injection and thereafter. Double immunofluorescence study revealed that calponin 3 was induced in GFAP-positive astrocytes. These results suggest that calponin 3 induction in the neuroprotective penumbral area following 3-nitropropionic acid intoxication may play a key role in reactive astrogliosis in the striatum.

Background : The surgical removal of impacted mandibular third molar can result in considerable pain, swelling, and dysfunction that patient are incapable of work for several days. Factors contributing to post operative swelling, trismus and pain are complex. There is no question but that the procedure of surgically removing an impacted mandibular third molar is inherently a traumatic one and that some sequelae related to the inflammation response are expected. Meticulous surgical technique will minimize the sequelae of inflammation but will not prevent them. In an effort to minimize these sequelae the use of steroid was instituted. Patients and Methods : Present study was to investigate the effect of one preoperative steroid injection in the masseter muscle to the patients(male 9, female 11) who needed prophylactic removal of bilateral, symmetrical, impacted wisdom teeth in the mandible on the complaint like swelling, trismus and pain. through Double-Blind test. Results : 1. After 24 hours investigation, preoperative steroid injection had significantly reduced swelling with 39% and trismus with 57.5%. 2. $7^{th}$ post operative day investigation, reduced swelling and trismus had shown, however, not significant. 3. There wasn't major difference from the group who took preve-ntive steroid in the visual analogue scale, the first analgesic intake time and the pain period. 4. There wasn't any adverse reaction of steroid for 20 patient From the above result, If the patients are not contraindication to steroid and pronounced post operative reaction can be expected the use of steroid to the surgical removal of impacted mandibular third molar is recommended.

Few studies address the use of manual muscle stretching to improve spinal active range of motion(AROM). There is evidence that' Hold-Relax'(HR) is effective for increasing ROM in the extremities, which leads the researchers to anticipate similar benefits in the spine. The purpose of this study is to investigate the effects of HR(trunk flexors) and active thoracic flexion and extension on thoracic mobility, specifically flexion and extension in healthy individuals. A convenience sample of 30 physical therapy students(22-38 years) were randomly assigned to intervention sequence 'A-B' or 'B-A', with at least 7 days between interventions. Intervention' A' consisted of HR of the ventral trunk musculature while 'B' consisted of thoracic flexion-extension AROM. Thoracic flexion and extension AROM were measured before and after each intervention using the double inclinometer method. Paired t-tests were used to compare AROM pre and post-intervention for both groups, and to test for carry-over and learning effects. There was a statistically significant increase(mean=$3^{\circ}$ ; p=0.006) in thoracic extension following HR of the trunk flexors. There were no significant changes in thoracic flexion following HR, or in flexion or extension following the AROM intervention. No carryover or learning effects were identified. HR may be an effective tool for improving AROM in the thoracic spine in pain free individuals. Further investigation is warranted with symptomatic populations and to define the minimal clinical difference(MCD) for thoracic spine mobility.

This is a study about a platform realization measuring the extent of reaction in nerve, as giving a electrical impulse on a nerve pulp regulating a function of muscle, about a measurement of nerve reaction in the amount of current, the lasting time of current, and the position of electrode from a electrical impuls.The position of an electrode in a electrical nerve impuls have nothing to do with all nerves from exercise to all things. There is the Single Twitch Stimulation(STS), Train-of-four(TOF), and Double Burst Stimulation(DBS) in the form of nerve stimulation. This report is needed for selecting MCU of low electric power for a base in embedded system and measuring the extent of reaction after making a sensor interface to know sensitivity of measuring sensor in basic reaction of nerve impuls. The platform is realized to select a high efficiency AD Convertor for raising accuracy in measured data. As the platform in this report was developed for a medical appliances, it was designed to consider user safety in electric power Isolation when making electric power circuit.

Episiotomy is the commonest obstetrics intervention in the world to reduce severe perineal injuries. Its prevalence is 43% to 100% in primiparous women in Asia. Further, worldwide approximately 10-95% of pregnant women undergo episiotomy incision during birth. Delay in wound healing probably increases the risk of wound infection, changes the muscular structure, and ultimately causes muscle tone loss. So, wound care is of specific significance to postnatal maternal outcomes. Hence, this case study aimed to evaluate the effect of Marham-i-Raal in episiotomy wound healing and pain relief. The study was conducted in eleven postpartum primi or multipara pregnant women aged between group 19 and 35 years with term gestational age, singleton pregnancy in a cephalic presentation who had a normal vaginal delivery with mediolateral episiotomy, without a perineal tear, and perineal hematoma. Externally, application of Marham-i-Raal 2g on episiotomy incisional wound, twice a day for 10 days was advised. Wound healing of episiotomy and pain intensity was assessed with REEDA ["redness, oedema, ecchymosis, discharge and approximation of the edges"] scoring and VAS scoring for pain intensity respectively. At one hour (baseline), the REEDA mean score of eleven patients was 3.90±1.04 whereas on day 7-10 it was 0.18±0.40 with statistically significant difference (p<0.001). The VAS mean score at one hour was 6.90±1.22 whereas on day 7-10 it was 0.72±0.78 with a statistically significant difference (p<0.001). Marham-i-Raal would be effective in episiotomy wound healing and reducing pain intensity. Further, randomized double-blind controlled trials in large sample size are recommended.

Purpose: Postoperative exercise for acute Achilles tendon rupture is important for a patient's return to daily life and sports. On the other hand, the protocol requires considerable effort to educate patients and continuous checking. This study evaluated the outcome of a new simple and delayed rehabilitation protocol after Achilles tendon rupture repair. Materials and Methods: From July 2014 to November 2020, one hundred eighty-three patients were operated on by one surgeon. The exercise protocol was classified into two methods. One group (immediate protocol, control group) started immediate full weight bearing with a 20° plantar flexion range of motion from two days postoperatively. Ankle dorsiflexion was restricted to 0°. The other group (delayed protocol, case group) started full weight bearing with a controlled ankle motion boot from two weeks postoperatively. No range of motion exercise was allowed until six weeks postoperatively. Age, sex, body mass index, ankle range of motion, muscle power, time to return to previous physical activity, functional score, and complication rate were evaluated. The results of the two groups were compared using a Mann-Whitney test. Statistical significance was set as p<0.05. Results: The range of motion, double heel rising, and one-leg standing were achieved faster in the control group (p<0.05). However, single-heel rising, repeated single-heel rising, return to previous activity (work, run, and sport), and functional scores showed no statistical difference (p>0.05). Conclusion: Simple and delayed postoperative rehabilitation of acute Achilles tendon rupture without active range of motion exercises showed satisfactory functional results and a low complication rate.
