Effects of aybusculayr mycorrhizal fungus (aMF), Glomus manihot, on plant growth and nutrient uptake on pepper (Capsicum annuum L.) seedlings were evaluated in the nursery experiment. Five different strains of pepper, Chungok, Shingang, Manitta, Gonggongchil, and Shintaeyang, were used in this study. Total fresh weight, nutrient (nitrogen, phosphate and potassium) uptake were increased in all strains inoculated with G. manihot alone and G. manihot and rock phosphate over control at 2 weeks after seeding. Plant weight and phosphate uptake in plants treated with AMF were significantly higher (P< 0.05) than those of control at 6 weeks after seeding. The treatment with G. manihot and rock phosphate gave better plant performance than the treatment with G. manihot alone at 6 weeks after seeding. The lengths of pathogenic symptom on pepper by Phytophthora capsici were reduced significantly by the inoculation of G. manihot spores, Therefore, it would be expected that AMF can be used as the biocontrol agent on pathogens in pepper.

The effect of dual inoculation with vesicular-arbuscular (VA) mycorrhizal fungi, Glomus mosseae, and Bradyrhizobium sp. R938 on the nitrogenase activity of peanut plant (Arachis hypogeae L. cv. Youngho) was studied in pot experiment. As a result of the dual inoculation with Glomus mosseae and Bradyrhizobium on peanut plant, nitrogenase activity was increased by 1.5 times compared with single inoculation with Bradyrhizobium sp. R938. After 69 days growth of peanut plant, the size of nodules was also increased due to the mycorrhizal infection. The mean fresh weight per nodule was 6.7 mg in treatment with the dual inoculation, which is the 1.5 times increase compared with single inoculation with Bradyrhizobium sp. R938. These results suggested that there might be a hormonal effect of VA mycorrhizal fungi in addition to the effect of increase in nitrogen fixing ability through the enhancement of nutrient absorption.

Purpose: Glomus tumors are rare benign vascular tumors, usually located in the skin or soft tissue of extremities. Approximately 30-50% of glomus tumors occur in subungal area, but glomus tumors have been described in every location even where glomus bodies are not or rarely present. The purpose of this study was to identify clinical, histologic and MRI characteristics of soft tissue glomus tumor. Materials and Methods: Between 1993 and 2008, eight patients underwent surgery of soft tissue Glomus tumor at our institution. Exclusion criteria were patients with Glomus tumors in digits, stomach, trachea and glomus tympanicum. We analyzed medical records, interviews, physical examinations, MR findings and histolocial types retrospectively. Results: There were four men and four women. The mean age was fourty-seven years. The mean prevalence time was eight-point-nine years. In the classic triad of symptoms, all eight patients had pain and tenderness. Two patients complained of cold sensitivity. Two showed skin color changes. After surgery, two showed symptom improvement (VAS $9^{\circ}{\rightarrow}8$, $8^{\circ}{\rightarrow}5$) and?six showed complete disappearance of symptoms. Slightly symptom improvemented (VAS $9^{\circ}{\rightarrow}8$) one had additional surgery two times after first surgery due to relapse/remaining Glomus tumor. The mean size was 13.9 mm. In histology, six were 'solid glomus tumor', one was a mixture of 'solid glomus tumor' and 'lomangioma' and one was 'malignant glomus tumor'. MR findings showed isointense signal on T1 image, high signal on T2 image and strong enhancement on the Gadolinium enhanced image. Conclusion: Glomus tumor has low recurrence rate and malignant change, rapid diagnosis and surgical excision is critical in treatment to prevent unnecessary pain of patient.

Glomus tumors are uncommon lesions of glomus cell origin with structural and immunohistochemical features of smooth muscles. Primary glomus tumors of the lung and bronchus are extremely rare and only several cases have been reported. A 16-year-old woman was admitted for the complaint of productive cough, fever, and dyspnea. Imaging studies revealed a protruding mass in the left main bronchus and the mass was completely resected via a left thoracotomy incision. We report this case with literature review.

Glomus tumours are vascular hamartomas that are commonly found in the hand, particularly the subungual region. They appear as solitary or multiple tumours, and often present as a bluish discoloration of the nail plate. Different diagnostic tests are outlined, as well as imaging studies such as magnetic resonance imaging and ultrasound. Misdiagnosis and delayed diagnosis of these tumours are common, while a familial tendency is a potential risk factor but not yet proven. Complete surgical excision often results in complete symptomatic relief, while recurrences are largely due to incomplete excision or the growth of a new glomus tumour. This article aims to review the key aspects of glomus tumours and provide a diagnostic algorithm so that the lesion can be recognized and treated earlier.

Effect of dual inoculation with vesicular-arbuscular(VA) mycorrhizal fungi, Glomus mosseae, and Rhizobium meliloti R455 on growth, nodulation, and nitrogenase activity of alfalfa (Medicago sativa L. cv. Vernal) were examined in pot experiment. After 63 days growth, shoot length, number of leaf, and leaf size of alfalfa were increased as as result of dual inoculation with Glomus mosseae and Rhizobium meliloti. Total dry weight of alfalfa plant was increased 1.4 times compared to single inoculation with Rhizobium meliloti. Nodule number and mean fresh weight of nodule per plant were also increased due to the mycorrhizal infection.

Glomus tumors are small vascular tumors that are usually benign and rarely occur. They originate from glomus bodies and present in the reticular dermis. They are clinically distinguished by their small size and their ability to cause extreme pain. Most of these tumors are subungually located. However, atypical locations of the tumors sometimes cause misdiagnosis, particularly when the lesion is rarely reported. Therefore, we report a case of glomus tumor which presented with chronic abdominal pain, found in the abdominal wall that has never been reported before.

Glomus tumors are a rare, benign neoplasm and 75% exist in the subungual region. Extradigital glomus tumors are much more difficult to diagnose because of their atypical location and symptoms. Furthermore, if their symptoms are similar to neuropathic pain, the patient can suffer from misdirected treatment due to misdiagnosis. It is essential to perform careful evaluation of the lesion itself in order to reduce misdiagnosis. Ultrasonography is a useful, non-invasive method that can be easily performed in the pain clinic for local evaluation and diagnosis. We report a case of misdiagnosed glomus tumor in the thigh which was properly diagnosed after ultrasonography.

Malignant glomus tumor is a very rare disease originating from the paraganglia system through the body. Glomus tumor, also known as paraganglioma, usually are considered benign, and arises in a variety of head and neck locations, most of which include the carotid body, the vagus nerve, and the jugulotympanic area. The most widely accepted management of benign glomus tumor is surgical extiration. Here, we report a case of recurrent laryngeal glomus tumor which is proven malignant and metastatic to the brain and the lungs. We have treated the patient with combination chemotherapy and radiation to the brain, the result of which is partial response in terms of decreased size of metastatic lung lesions.

Glomus tumor is uncommon tumor with an incidence of about 1% in soft tissue tumors and the single most common location is the subungual region of the finger. Many reports have emphasized that glomus tumors were difficult to diagnose and that the result of surgical removal was good, but nail deformity has received little attention. Most of authors removed the entire nail or partially splitted the nail to exposure the nail bed and tumor. Nobody reported whether nail deformity after operation was present or not. But, an abnormal nail is both a cosmetic and a functional problem in that catches on objects. In this study, our attention was postoperative nail deformity as well as the results of surgical removal. Seven patients(eight cases) who were diagnosed as a subungal glomus tumor in the hand were treated by surgical excision without removal of the nail and followed over twenty two months. And then we report on our experience with 8 cases of subungual glomus tumor which were successfully treated by complete excision without nail deformity.
