Purpose: Nerve injury is one of the complication which can develop after brow lift. Peripheral nerve ending which is stretched from supraorbital nerve and supratrochlear nerve can be injured and symptoms such as pain, dysesthesia may appear. Usually, developed pain disappeared spontaneously and does not go on chronic way. We experienced a case that a patient complained chronic pain after brow lift which was not controlled by conservative management such as medications, local nerve block and report a successful surgical treatment of chronic pain after brow lift. Methods: A 24-year-old male who received brow lift with hairline incision at local hospital was admitted for chronic pain at the right forehead. The pain was continued for 3 months even though fixed thread was removed. Local nerve block at trigger point with mixed 1 mL 2% lidocaine and 1 mL Triamcinolone acetonide was done and oral medications, Gabapentine and carbamazepine, were also applied but there was no difference in the degree of pain. Therefore the operation was performed so that careful dissection was carried out at right supraorbital neurovascular bundle and adhered supraorbital nerve was released from surrounding tissues and covered with silastic sheet to prevent adhesion. Results: The pain was gradually relieved for a week. The patient was discharged without complications. No evidence of recurrence has been observed for 2 years. Conclusion: The pain developed after brow lift was engaged with nerve injury and sometimes remains chronically. Many kinds of conservative management to treat this complication such as medications, local nerve block have been reported and usually been used. But there are some chronic cases that conservative treatment do not work. In sum, we report 1 case of successful surgical treatment for relief of intractable pain developed after brow lift surgery.

In adult congenital muscular torticollis (CMT) patients, physical therapy is not as effective because the development of sternocleidomastoid muscle (SCM) muscle is complete. While surgical release can address CMT in adult patients, the risk of general anesthesia and visible postoperative scar is a concern, expecially in patients with mild symptoms. In this paper, we report our experience in treating such patients with minimal-incision myotomy under local anesthesia. A review was performed for all adult patients who had undergone the simple myotomy procedure. Surgical indication was reserved for patients with mild fibrotic band in the SCM muscle with minimal lengthdiscrepancybetween the muscles. All patients had recognizable head tiltand palpation of fibrotic band on affected side of the neck. Surgical details are described in the main body of text. Three female patients had undergone the procedure. Torticollis was resolve in all patients with complete restoration of ranage of motion. There were no postoperative complications, and patient satisfaction was high. We have reported three cases of mild CMT in adult female patients, who had undergone minimal-incision myotomy under local anesthesia. Outcomes were satisafactory with no morbidity to report. With careful patient selection, this method offers an alternate treatment option for adult CMT patients with mild symptoms.

국내 산악 지역 자연공원에서는 자연 환경과 주변 조망을 보존하기 위해 전차선의 설치가 불가하다. 따라서 산악 트램은 무가선으로 운행되어야 한다. 이를 위해 본 연구에서는 차량의 추진 배터리에 전기를 공급할 수 있는 지상 집중식 급전장치를 개발하고 동작 및 기능 시험을 실시하여 성능을 검증하였다. 개발한 지상 집중식 급전장치는 검수고 또는 정거장의 한 지점에 고정 설치되어 있으며, 차량의 대차가 진입하여 정차하면 스프링 장력으로 암과 집전 슈를 올려 대차 하부에 있는 차량측 집전 바와 접촉하고, 전기를 흘려 배터리에 전력을 공급한다. 지상 집중식이므로 차량 지붕 위의 집전장치와 전차선이 필요 없게 되고, 산악트램은 무가선 상태로 운행을 할 수 있다. 정거장이나 검수고에서 움직이지 않고 정지한 상태에서 집전하므로, 이선이나 아크 발생이 없다. 집전 슈의 마모나 손상을 초래할 수 있는 가동 접촉면이 사라지게 되므로 집전장치 수명이 연장되는 장점이 있다. 시험 결과에 따르면, 절연저항은 기준치인 10㏁ 이상이었고, 전류 335A를 1시간 동안 일정하게 공급하여도 이상 발열이 없음을 확인하였다.

Effect of molasses addition to complete calf starter (CCS) and the following pellet processing was evaluated with 12 Holstein-Friesian (HF) calves (7-14 d old with $42\;{\pm}\;5.5\;kg$ average BW), with 6 calves (replicate) per treatment. The CCS was formulated with 65% concentrate calf starter and 35% local corn fodder. On the CCS, molasses was added either 5% (M5) or 10% (M10), then the mixture was pelleted and fed to the calves for 7 weeks. Molasses addition, regardless of addition level, improved (p<0.05) both the durability and hardness of the pellet which contains 35% of high fibrous local corn fodder. Upon feeding to calves, the feed intake and daily gain were numerically higher with 5% molasses addition compared to 10% molasses addition. Blood VFA level was remarkably higher (p<0.01) in calves fed M10 than calves fed M5. There was no difference (p>0.05) in blood glucose level between M5 and M10. Length and number of papillae were not different (p>0.05) by the addition levels of molasses. However, there was one exception in number of papillae at caudo-dorsal sac which were higher (p<0.05) number in M5 than M10 calves. Considering the quality of CCS pellet, calf performance and rumen development, there was no additional benefit of 10% molasses addition compared to 5%. From the results of this study, 5% molasses addition could be recommended for local farmer when they utilize local corn fodder to make CCS for HF calves in Indonesia.

Objectives : This study was designed to investigate the anti-obesity effects in local area adipose tissue using by pharmacopuncture of Eriobotryae Folium on mice fed high fat diet. Methods : Male ICR mouse were divided into three groups. Normal diet group (N), High-fat diet(HFD) group, HFD+E(pharmacopuncture of the Eriobotryae Folium) group for 8 weeks. HFD+E group was injected in the concentration of 50 mg/kg once a day for 4 weeks and every other day during the next 4 weeks. We measured body weight, food intake, absolute weight and relative weight in the liver and adipose tissue. Also, we analyzed hematological levels and histopathological changes on adipose tissue. Results : 1. We observed no difference in food intake among three groups. 2. HFD+E group significantly decreased body weight gain and absolute weight and relative weight in the liver and adipose tissue compared with HFD group. 3. Blood AST and ALT were no differences among the experiment groups. However, HFD group was significantly increased higher TG, TC, HDL and LDL than in N group and HDL/LDL ratio was remarkably decreased. On the other hand, HFD+E group was significantly decreased in obesity markers and HDL/LDL ratio was remarkably increased. 4. Levels of adiponectin in serum of HFD+E group was remarkably increased compared with those of HFD group. 5. HFD group was significantly decreased compared with N group in adipocyte number. Compared with the HFD group, HFD+E group was displayed a significant increase by adipocyte number. Conclusions : We suggest that pharmacopuncture of the Leaves of Eriobotrya japonica can play the anti-obesity effects in local area adipose tissue.

Background: Lignocaine with adrenaline is routinely used as a local anesthetic for dental procedures. Adrenaline was added to increase the duration of anesthesia. However, epinephrine containing a local anesthetic solution is not recommended in conditions such as advanced cardiovascular diseases and hyperthyroidism. Recently, ropivacaine has gained popularity as a long-acting anesthetic with superior outcomes. The goal of this study was to assess and compare the effectiveness of 0.75% ropivacaine alone and 2% lignocaine with adrenaline (1:80,000) in the removal of bilateral maxillary wisdom teeth using the posterior superior alveolar nerve block technique. Methods: This was a single-blind, randomized, split-mouth, prospective study assessing 15 systemically sound outpatients who needed bilateral removal of maxillary third molars. We randomly allocated the sides and sequences of ropivacaine and lignocaine with adrenaline administration. We evaluated the efficacy of both anesthetics with regard to the onset of anesthesia, intensity of pain, variation in heart rate, and blood pressure. Results: The onset of anesthesia was faster with lignocaine (138 s) than with ropivacaine (168 s), with insignificant differences (p = 0.001). There was no need for additional local anesthetics in the ropivacaine group, while in the lignocaine with adrenaline group, 2 (13.3%) patients required additional anesthesia. Adequate intraoperative anesthesia was provided by ropivacaine and lignocaine solutions. No significant difference was observed in the perioperative variation in blood pressure and heart rate. Conclusion: Ropivacaine (0.75%) is a safe and an adrenaline-free local anesthetic option for posterior superior alveolar nerve block, which provides adequate intraoperative anesthesia and a stable hemodynamic profile for the removal of the maxillary third molar.

Size distributions of atmospheric particulate matter (PM) and its water-soluble organic and inorganic components were measured between January and February 2021 at an urban site in Gwangju in order to identify the major factors that determine their size distributions. Their size distributions during the study period were mainly divided into two groups. In the first group, PM, NO₃^-, SO₄^2-, NH₄⁺ and water-soluble organic carbon (WSOC) exhibited bi-modal size distributions with a dominant condensation mode at a particle size of 0.32 ㎛. This group was dominated by local production of secondary water-soluble components under atmospheric stagnation and low relative humidity (RH) conditions, rather than long-range transportation of aerosol particles from China. On the other hand, in the second group, they showed tri-modal size distributions with a very pronounced droplet mode at a diameter of 1.0 ㎛. These size distributions were attributable to the local generation and accumulation of secondary aerosol particles under atmospheric conditions such as atmospheric stagnation and high RH, and an increase in the influx of atmospheric aerosol particles by long-distance transportation abroad. Contributions of droplet mode NO₃^-, SO₄^2-, NH₄⁺ and WSOC to fine particles in the second group were significantly higher than those in the first group period. However, their condensation mode contributions were about two-fold higher in the first group than in the second group. The significant difference in the size distribution of the accumulation mode of the WSOC and secondary ionic components between the two groups was due to the influx of aerosol particles with a long residence time by long-distance transport from China and local weather conditions (e.g., RH).
