Single-strand conformation polymorphism of sequence-tagged site markers based on partial sequences of cDNA clones in Cryptomeria japonica. (2/107)Sixty-seven sequence-tagged site (STS) markers were identified from partial sequences of cDNA clones obtained from the inner bark of Cryptomeria japonica. Polymorphisms of the STSs were investigated for the parental clones of a mapping population, Haara and Kumotooshi, using both single-strand conformation polymorphism (SSCP) and sequencing analysis. Twenty-two STSs showed nucleotide differences between Haara and Kumotooshi, of which 19 STS differences were detectable under the electrophoresis conditions we used here. We also analyzed SSC-polymorphism in 10 additional clones derived from various Japanese regions to evaluate the usefulness of the STSs developed here among other populations of C. japonica. Twenty-five, about 40%, of the STSs showed polymorphism under selected electrophoresis conditions. The genotype segregation for 19 STSs was investigated among the Haara x Kumotooshi F(1) population, and these STS markers were mapped on a linkage map. SSCP analysis of STSs was efficient in terms of cost and time, and it allows detection of a sufficiently high proportion of polymorphisms to provide a convenient means for mapping of expressed sequences on a linkage map and for studying various aspects of population genetics.

Three T-cell determinants of Cry j 1 and Cry j 2, the major Japanese cedar pollen antigens, retain their immunogenicity and tolerogenicity in a linked peptide. (3/107)It has been demonstrated in detail that administration of a dominant T-cell determinant to animals induces activation or immunological tolerance of T cells. However, it has not been determined whether multiple T-cell determinants, when integrated into a single peptide, retain their potential to induce T-cell activation and tolerance. We prepared a synthetic peptide comprising three T-cell determinants of Cry j 1 and Cry j 2, the major Japanese cedar pollen antigens, and investigated the immunogenicity and tolerogenicity of each T-cell determinant in the linked peptide by means of lymph node cell proliferation assays using mice. Lymph node cells from mice immunized with each of the three T-cell determinants proliferated against the linked peptide in a dose-dependent manner, similar to that of the immunized peptide. Lymph node cells from mice immunized with the linked peptide proliferated against all of the three T-cell determinants. In addition, the degree of proliferation against the three T-cell determinants occurred according to their original immunogenicity, as observed in the native protein antigens. Oral administration of the linked peptide to mice before they were immunized with Cry j 1 and Cry j 2 inhibited lymph node cell proliferation against the three T-cell determinants, depending on the dose of the linked peptide administered. In conclusion, it was demonstrated that three T-cell determinants retain their original immunogenicity and tolerogenicity in a linked peptide comprising them. (+info)
Oral allergy syndrome induced by tomato in a dog with Japanese cedar (Cryptomeria japonica) pollinosis. (4/107)A dog with Japanese cedar (Cryptomeria japonica, CJ) pollinosis had oral allergy syndrome (OAS) after ingesting fresh tomato. The dog showed specific IgE to both CJ and tomato allergens. As a negative control, twenty dogs without atopic dermatitis that had no exposure to tomato and no specific IgE to CJ allergen were used. They had no specific IgE to tomato allergen. Furthermore, IgE cross-reactivity was observed between CJ and tomato allergens in the dog. We found that OAS induced by tomato exists in the dog and there is a relationship between CJ and tomato allergens. (+info)
Repellents in the Japanese cedar, Cryptomeria japonica, against the pill-bug, Armadillidium vulgare. (5/107)Sandaracopimarinol and (1S,6R)-2,7(14),10-bisabolatrien-1-ol-4-one were isolated and identified from Cryptomeria japonica as repellents against Armadillidium vulgare which is well known as an unpleasant pest in the house and as vegetable pest in Japan. These compounds strongly repelled A. vulgare when they were combined, although each compound alone did not show any activity. (+info)
Isolation and characterization of cDNAs that encode homologs of a pathogenesis-related protein allergen from Cryptomeria japonica. (6/107)Many plant pathogenesis-related (PR) proteins are allergenic. We isolated three cDNAs, Cry j 3.1, Cry j 3.2, and Cry j 3.3, that encoded homologs of Jun a 3, a PR protein allergen in Juniperus ashei, from a cDNA library derived from the pollen of Cryptomeria japonica. The predicted amino acid sequences encoded by the three cDNAs were more than 85% identical to each other and about 57% identical to the sequence of Jun a 3. The Cry j 3 genes seemed to form a small multigene family in the genome of C. japonica. Expression of Cry j 3 was strong in roots and in female and male strobili; expression was weaker in cotyledons, leaves, stems, and pollen grains. (+info)
Anti-allergic substances contained in the pollen of Cryptomeria japonica possess diverse effects on the degranulation of RBL-2H3 cells. (7/107)Following prolonged exposure to some of the flavonoids with RBL-2H3 cells, secretion of hexosaminidase, a granule constituent, stimulated by an immunologic was enhanced. RBL-2H3 cells do not normally respond to polybasic secretagogues, but as reported here, they do so after prolonged exposure. Effect of flavonoids on secretion of hexosaminidase was also investigated. Of the thirteen flavonoids, quercetin and fisetin were the most potent inhibitors. A structure-activity study indicated that the position, number, and substitution of the hydroxy group of the B ring and saturation of the C2-C3 bond are important factors affecting flavonoid inhibition of secretary granules in RBL-2H3 cells.

An approach for the conquest of the sugi pollinosis using plant growth regulation. (8/107)The sugi (Cryptomeria japonica) pollinosis becomes representative allergic disease in early spring in Japan. However, effective treatment for the sugi pollinosis and countermeasure against pollen of C. japonica at its source have not been developed in a practical sense. In this paper, the research aiming to prevent dispersion of pollen of the C. japonica is introduced on application and practical application to the field from the laboratory using the growth regulation of the plant. We found that formation of male flower bud in C. japonica could be suppressed by TNE, since the 3 beta-hydroxylase is inhibited by the action of Trinexysapacethyl, TNE. (+info)
In the medical field, Cryptomeria refers to a type of evergreen tree that belongs to the Cupressaceae family. The scientific name of Cryptomeria is Cryptomeria japonica, and it is commonly known as the Japanese cedar or hinoki. Cryptomeria is native to Japan, Korea, and China, and it is widely cultivated in other parts of the world for its wood, which is used in construction, furniture making, and paper production. The tree can grow up to 30 meters tall and has a conical shape with a smooth, gray bark. In traditional medicine, Cryptomeria has been used for a variety of purposes, including as an antiseptic, anti-inflammatory, and analgesic. The essential oil extracted from the tree has been shown to have antimicrobial and antifungal properties, and it is used in some natural remedies for respiratory infections and skin conditions. However, it is important to note that the use of Cryptomeria in medicine should be done under the guidance of a qualified healthcare professional, as some of its compounds may have potential side effects or interact with other medications.
In the medical field, cambium refers to the layer of cells in plants that is responsible for the growth and development of new tissues. It is located between the bark and the wood of a tree, and is responsible for producing new cells that differentiate into xylem (the tissue responsible for water transport) and phloem (the tissue responsible for nutrient transport). The cambium plays a critical role in the growth and maintenance of trees and other woody plants, and any damage or disruption to this layer can have significant impacts on the health and longevity of the plant.
In the medical field, "Antigens, Plant" refers to substances found in plants that can trigger an immune response in the body. These substances, also known as plant antigens or allergens, can cause an allergic reaction in some individuals who come into contact with them. Plant antigens can be found in a variety of plant-based products, including fruits, vegetables, nuts, seeds, and grains. Some common examples of plant antigens that can cause allergic reactions include pollen from trees, grasses, and weeds, as well as certain types of fruits and vegetables like peanuts, tree nuts, and shellfish. When a person with a plant allergy comes into contact with an antigen, their immune system responds by producing antibodies to fight off the perceived threat. This can lead to symptoms such as itching, hives, swelling, and difficulty breathing, depending on the severity of the reaction. Treatment for plant allergies typically involves avoiding exposure to the allergen and taking medications such as antihistamines or epinephrine to manage symptoms. In some cases, immunotherapy may also be recommended to help desensitize the immune system to the allergen over time.
Diterpenes, Abietane are a group of diterpenes that are derived from the resin of coniferous trees, particularly the pine family. They are characterized by their abietane skeleton, which consists of a six-membered ring with two methyl groups attached to it. In the medical field, diterpenes, Abietane have been studied for their potential therapeutic properties. Some of the compounds in this group have been found to have anti-inflammatory, anti-cancer, and anti-viral effects. For example, abietic acid, a diterpene found in pine resin, has been shown to have anti-inflammatory and anti-cancer properties in laboratory studies. However, more research is needed to fully understand the potential therapeutic applications of diterpenes, Abietane and to determine their safety and efficacy in humans.
Coniferophyta is a division of plants that includes conifers, which are trees and shrubs that produce cones and have needle-like leaves. Conifers are a major group of gymnosperms, which are plants that produce seeds without enclosing them in a fruit. In the medical field, conifers are often used for their wood, which is strong and durable and can be used for a variety of purposes, including construction, furniture making, and paper production. Some species of conifers, such as the pine tree, are also used for their essential oils, which have a variety of medicinal properties and are used in aromatherapy and other forms of alternative medicine.
Sesquiterpenes are a class of organic compounds that are derived from terpenes, which are a large and diverse group of natural compounds found in plants, fungi, and some bacteria. Sesquiterpenes are characterized by their molecular formula, which contains 15 carbon atoms arranged in a specific pattern. In the medical field, sesquiterpenes have been studied for their potential therapeutic properties. Some sesquiterpenes have been found to have anti-inflammatory, anti-cancer, and anti-viral effects. For example, some sesquiterpenes have been shown to inhibit the growth of cancer cells and to reduce inflammation in the body. Sesquiterpenes are also used in traditional medicine and are found in a variety of plants, including chamomile, sage, and valerian. Some sesquiterpenes have been used to treat a variety of conditions, including anxiety, insomnia, and digestive disorders. Overall, sesquiterpenes are a promising class of compounds with potential therapeutic applications in the medical field. However, more research is needed to fully understand their properties and potential uses.
Rhinitis, allergic, seasonal, is a type of inflammation of the nasal passages that occurs in response to exposure to allergens, such as pollen, mold spores, or dust mites, that are typically present in the environment during certain times of the year. It is also known as seasonal allergic rhinitis or hay fever. Symptoms of seasonal allergic rhinitis can include sneezing, runny nose, itchy or watery eyes, congestion, and postnasal drip. These symptoms are usually worse in the morning or after exposure to allergens and can be relieved with over-the-counter antihistamines or nasal decongestants. Seasonal allergic rhinitis is a common condition that affects millions of people worldwide. It is typically treated with avoidance of allergens, the use of medications to relieve symptoms, and immunotherapy (allergy shots) to reduce sensitivity to allergens over time.
In the medical field, an allergen is a substance that triggers an allergic reaction in a person. When a person with an allergy comes into contact with an allergen, their immune system reacts by producing antibodies called immunoglobulin E (IgE). These antibodies bind to cells in the body, causing them to release chemicals such as histamine, which can cause symptoms such as itching, swelling, and difficulty breathing. Allergens can be found in a wide range of substances, including foods, pollen, dust mites, pet dander, insect stings, and medications. Some common allergens include peanuts, tree nuts, shellfish, milk, eggs, wheat, soy, fish, and sesame seeds. Allergens can be inhaled, ingested, injected, or touched, and the severity of an allergic reaction can vary widely depending on the individual and the allergen. In severe cases, an allergic reaction can be life-threatening and require immediate medical attention.
