Vertigo is an illusion of rotation, which results from an imbalance within the vestibular system. This review focuses on two common presentations of spontaneous vertigo: acute prolonged spontaneous vertigo and recurrent spontaneous vertigo. Common causes of acute prolonged spontaneous vertigo include vestibular neuritis, labyrinthitis, and brainstem or cerebellar stroke. The history and detailed neurological/neurotological examinations usually provide the key information for distinguishing between peripheral and central causes of vertigo. Brain MRI is indicated in any patient with acute vertigo accompanied by abnormal neurological signs, profound imbalance, severe headache, and central patterns of nystagmus. Recurrent spontaneous vertigo occurs when there is a sudden, temporary, and largely reversible impairment of resting neural activity of one labyrinth or its central connections, with subsequent recovery to normal or near-normal function. Meniere's disease, migrainous vertigo, and vertebrobasilar insufficiency (VBI) are common causes. The duration of the vertigo attack is a key piece of information in recurrent spontaneous vertigo. Vertigo of vascular origin, such as VBI, typically lasts for several minutes, whereas recurrent vertigo due to peripheral inner-ear abnormalities lasts for hours. Screening neurotological evaluations, and blood tests for autoimmune and otosyphilis are useful in assessment of recurrent spontaneous vertigo that are likely to be peripheral in origin.

Neck mass is a common manifestation from head and neck malignancy, most of which come from mucosal squamous cell carcinomas in the upper aero-digestive tract. However, once aspiration cytology suggests atypical malignant cells in the neck mass rather than metastatic squamous cell carcinomas, it is confusing to decide the adequate diagnostic work-ups and treatment planning. Here, we report a 29-year-old woman presenting with a growing neck mass mimicking malignancy of unknown origin, which was finally diagnosed as primary lymphoepithelial carcinoma in the parotid gland with multiple metastases to the lymph nodes. The patient underwent comprehensive neck dissection and total parotidectomy and the adjuvant radiation treatment was given. Our report highlight that the primary salivary gland cancer should be considered as the potential tumor origin in case of malignancy of unknown origin in the head and neck region and neck mass suggestive of atypical carcinomas.

Since the first report of a nasal septal abscess (NSA) from a dental origin (1920), six articles have been published in the English literature to date. The most common cause of NSA is an infection of the nasal septal hematoma after trauma. This is a report of an uncommon cause of NSA with a dental origin. A PubMed search performed regardless of year and country using the terms ("nasal septal abscess") OR ("nasal septum abscess") initially yielded 229 articles. After screening, seven articles (eight patients) were selected. Addition of two related articles produced a total of nine articles (10 patients) to be included. The age of the included patients ranged from 7 to 69 years (mean, 32.82 years; standard deviation, ±23.86 years). The sex composition was as followed: males (n=7; 63.6%), females (n=4; 36.4%). Dental histories were various: periapical lesions, caries, extraction, endodontic therapy, and cystic lesions. The maxillary incisor dominated as the tooth of origin. Early diagnosis and treatment of NSAs are important to avoid not only facial deformity, but also severe complications (e.g., intracranial infection). If NSA is suspected in patients without facial trauma, the possibility of a dental origin, especially from the maxillary incisor area, should be considered.

The present paper reviews the findings of different research studies on the effect of natural ingredients in the Japanese quail (Coturnix coturnix japonica) diet on carcass characteristics and meat quality. The results show a relationship between the type and concentration of ingredients used in diets and carcass characteristics and meat quality. The inclusion of medicinal herbs (thyme, black seed, and mint), plants (canola), seeds (chickpea), spices (cinnamon and coriander), worms (earthworms), bee products (propolis), phytochemicals (lycopene), and edible fungi (common mushrooms) in the diet improved carcass quality characteristics compared to the control diets (basal diets). The inclusion of medicinal herbs (spearmint and green tea), spices (cinnamon), vegetables (tomato), plants (verbena and canola), seeds (marijuana), and edible fungi (oyster mushrooms) improved meat quality. In conclusion, the use of ingredients of natural origin in the diet of Japanese quail improves carcass quality characteristics and meat quality.

Recently, the Trump administration initiated a new United States-Mexico-Canada Agreement (USMCA) that strengthened NAFTA's rules of origin to enhance protectionism while maintaining the framework of trade agreements rather than completely abolishing them. This study focuses on the behavior of firms motivated to influence the government to practice protectionist trade by analyzing the rules of origin verification and adopting the political economics model. This paper explains the process of endogenous determination of the stringency of rules of origin verification as a non-tariff barrier using the lobbying model. Comparative static analysis shows that the more efficient technology a domestic firm has and the more government prefers to raise political contribution, the more is verification likely to be strict. This suggests that a rationale exists to maintain a free trade agreement in the form of the new agreement (USMCA) without abolishing the current NAFTA regime.

Objectives : The purpose of this study is to analyze the origin plants, the habitat and the characteristics of the origin-plants of the medicine herbs belong to Araceae. Methods : To achieve the purpose of this study 48 bibliographies about 4 kinds of herbs belong to Araceae were examined. The examination was focused on the origin plants, habitat, the efficacy. Standing on this analysis the list and characteristics of the origin-plants were presented. Results : The results indicated that 1. In the original plants of 4 kinds of herbs, there were 27 species of scientific name totally, 25 species belonged to Araceae, and 2 species didn't. The origin plants of Pinelliae rhizoma were 3 species of different family plant, 16 species for Arisaematis Rhizoma, 2 species for Typhoni Rhizoma, and 6 species for Acori Graminei Rhizoma. 2. In the view of its authenticity, there was one kind of genuine species, 2 species of substitutes in the origin plants of Pinelliae Rhizoma, 14 kinds of genuine species, 2 species of substitutes in the origin plants of Arisaematis Rhizoma, and Whole origin plants of Typhoni Rhizoma, Acori Graminei Rhizoma were genuine species. 3. According to the habitat, there were 15 species distributed in Korea, China and so on. And 16 species were distributed in Korea, 25 species were of foreign origin. 1 species was unknown. 4. The each efficacy of origin plants were reported in the main subject Conclusions : Among the 4 medicinal herbs in the commonly using family Araceae, there were 27 origin plants(25 species belong to Araceae, and 2 species doesn't), so the number of origin plants are almost 6.75 times compared with the cases of the herbal name. Also, according to the habitat, approximately 59.3% of origin plants were producted in Korea, and approximately 92.6% of origin plants were of foreign origin.

Purpose: Abdominal cysts of gastrointestinal origin are rare. Their rarity and varied clinical presentations make their pre-operative diagnosis difficult. Methods: Fourteen patients with histological diagnosis of cysts of gastrointestinal origin admitted between 2009 and 2015 were retrospectively analyzed with respect to age, sex, clinical presentation, diagnostic modality, site and type of cyst, management, outcome and follow-up. Results: The mean age at presentation was 4 years and there were six males and eight females. Abdominal pain was the most common presenting symptom. Five patients had an acute presentation-three had distal ileal mesenteric cysts and two had ileal duplication cyst sharing a common wall with ileum. Six patients presented with chronic abdominal pain and lump-three patients had omental cysts and three had mesenteric cysts-two of these in distal ileum and one in sigmoid colon. Two patients presented with antenatally diagnosed palpable abdominal lump. One had a mesenteric cyst of the ileum and the other had a distal ileal duplication cyst which required excision with resection and anastomosis. One patient had an atypical presentation. He was a known case of sickle cell trait and had presented with vague abdominal pain, recurrent cough and multiple episodes of haemoptysis over a period of one year. At laparotomy, gastric duplication cyst was found which was excised completely. Histopathology confirmed the diagnosis. Conclusion: Cysts of gastrointestinal origin are rare and have varied presentation. Surgical excision is the mainstay of treatment. The results and prognosis are good.

우리나라를 인삼 종주국으로 자리매김한 고려인삼의 기원은 산삼이다. 그 산삼의 채삼 관습의 근거를 조선왕조실록, 일제 강점기 법령, 우리나라 산림법령과 민법 등에서 찾고자 하였다. 조선 시대와 일제 강점기 이전에는 심마니 채삼 관습은 입회관행으로 존재하였지만, 1910년 일제는 강점기 동안 우리나라 고유한 입회권 법리를 왜곡하였다. 일제가 왜곡한 입회권 법리는 해방 이후에 계속돼 1960년 민법 시행 때까지 유지되었다. 민법 시행 이후 입회권 법리는 특수지역권으로 바뀌었다. 입회권의 연원은 조선 시대의 시초장으로 난방용 땔감이나 사료용 풀을 채취할 수 있는 시초장은 조선 시대 그 당시 지역주민이 생존할 수 있는 최소한의 생존권이자 권익이었다. 생존권으로서의 입회권이었기 때문에 일제가 이를 폐지하려고 시도하였지만 실패하였다. 그럼에도 일제가 왜곡한 입회권 법리는 산림관련법령 등에서 지금까지도 유지되고 있다. 1945년 광복이 된 지 70년이 지난 이제는 일제의 심마니 채삼 관습에 관한 왜곡된 법리에서 탈피하여야 하고, 채삼 관행의 근거가 입회관행에서 민법상 특수지역권으로 변화된 것을 인정하여야 한다. 이에 심마니 단체는 법인 아닌 사단이고, 심마니의 채삼 관행은 민법상 특수지역권으로 법리 구성할 수 있고, 심마니의 산삼 채삼 행위는 관습법적으로 유효하다고 보아야 한다. 이를 통해 인삼과 관련된 산삼 채취행위에 관한 법적 성질과 그 근거를 명확히 할 수 있고, 심마니 채삼 행위의 민사법적 책임소재도 명확하게 할 수 있을 것이다.

Crude drug 'InDong(忍冬)' has been used mainly to cure common cold, high fever and gonorrhea. With regard to the botanical origin of InDong, it has been considered to be Lonicera species of Caprifoliaceae, but there was no pharmacognostical conformation on it. To clarify the botanical origin of 'InDong', the anatomical characteristics of the branches of Lonicera species growing wild in Korea, Lonicera japonica and L. japonica forma. chinensis were studied. As a result, it was clarified that InDong was the branches of Lonicera japonica.
