Pharmacological test shows that the externally-used preparation of Cetirizine has ideal allergy resistant and anti-inflammatory action to the rat passive cutaneous anaphylaxis (Rat PCA) model and dimethylbenzene caused mouse otitis model, and also prevents the adverse effect to the central system caused by whole body administration. It is also found in the test, that the externally used preparation of Cetirizine also has very fine inhibitory action to dinitrofluorobenzene caused mouse porphyria hypersensitivity (PTH), the novel pharmacological action of the Cetirizine shows that the Cetirizine external preparation has good therapeutic action to skin inflammations which mainly include porphyria hypersensitivity.

A method for the measurement of the activation of the basophils following stimulation with an allergen to determine hypersensitivity to some substances, in which a blood sample with an addition of interleukin-3 in a quantity of 0.05 to 50 ng/ml based on the volume of the sample, and of appropriately diluted allergen in a quantity of 0.5 to 100 units/ml is incubated at the temperature corresponding to the physiological environment for 15 to 45 minutes, whereafter a staining with anti-CD63.antibody in an amount of 3 to 30 .mu.l/100 .mu.l of blood and with the antibody against a receptor of the basophil in an amount of 3 to 30 .mu.l/100 .mu.l of blood are added at a temperature of 0 to +10.degree. C. and the sample, after vortexing, is then incubated in an ice bath for 15 to 30 minutes, and then is lysed and subjected to flow cytometry.

Novel compositions of matter containing aromatic compounds and terpenoids which are present in and may preferably be derived from the plant Alpinia galanga (Zingiberaceae) show synergistic effects with respect to immunomodulation, and they significantly suppress hypersensitivity reactions. Thus they are used for preparing medicaments for these purposes and, more specifically, for the treatment or prevention of IgE mediated allergic reactions and conditions, such as asthma, allergic rhinitis, atopic eczema or anaphylaxis, and autoimmune disorders, such as Crohn's disease, ulcerative colitis, rheumatoid arthritis or psoriasis, as well as for the alleviation of pain. They can for example be formulated into pharmaceuticals, cosmetics or dietary supplements. A method of preparing such compositions from Alpinia galanga is also described.

The present invention relates generally to therapy and diagnosis of disorders associated with chronic visceral hypersensitivity (CVH), and in particular irritable bowel syndrome (IBS). In particular, this invention relates to the polypeptides as well as to the polynucleotides encoding these polypeptides, wherein said polypeptides are shown to be associated with CVH. These polypeptides and polynucleotides are useful in the diagnosis, treatment and/or prevention of disorders associated with CVH, in particular in the diagnosis, treatment and/or prevention of disorders associated with IBS.

The invention discloses in-vitro tissue preserving fluid and a preparation method thereof. Each 1,000 milliliters of preserving fluid comprises the following components by weight: 5 to 200 grams of osmotic pressure regulator, 0.2 to 40 grams of a pH value buffer pair, 3 to 15 grams of potassium chloride, 1 to 5 grams of sodium chloride, 10 to 300 milligrams of antibiotic, 5 to 100 grams of glucose and the balance of deionized water. In the invention, a non-CO2 dependent buffer pair is used to reduce the dependence on CO2 in transport and an air exposure process and reduce the fluctuations of the pH value; a hypertonic and high-potassium environment is used to reduce the swelling of cells and tissues and improve the activities of the cells and tissues; and the antibiotic used is free from causing hypersensitivity reaction. The preparation method is simple and in-vitro tissue preserving fluid has a remarkable in-vitro tissue preserving effect. The in-vitro tissue preserving fluid is low in cost, has low transport requirements, and can be stored at room temperature and conveniently.

The invention relates to medicine and veterinary science and can be used for treating diseases associated with changes of the qualitative and/quantitative composition of blood extracellular DNA, namely generalised infection diseases provoked by bacteria, diseases provoked by fungi and protozoa, atherosclerosis, pancreatic diabetes, allergic diseases associated with delayed response hypersensitivity and diseases due to somatic cell gene mutations. The inventive method for treating diseases associated with modifications of the qualitative and/or quantitative composition of blood extracellular DNA, namely generalised infection diseases provoked by bacteria, diseases provoked by fungi and protozoa, atherosclerosis, pancreatic diabetes, allergic diseases associated with delayed response hypersensitivity and diseases due to somatic cell gene mutations consists in injecting an agent destroying blood extracellular DNA. DNAse enzyme injected into a systemic blood circulation in doses which modify the electrophoretic profile of the blood extracellular DNA definable by pulse-electrophoresis can be used in the form of an agent destroying said blood extracellular DNA. Said DNAse enzyme can be injected in doses and at regimes ensuring the level of a blood plasma DNA-hydrolytic activity which is measured in the blood plasma and is higher than 150 Kunz units per litre of plasma during a total time higher than 12 hours a day. The inventive method makes it possible to develop a high-efficient and low-toxic method for treating diseases associated with modifications of qualitative and/or quantitative composition of blood extracellular DNA individually or in combination thereof.

The invention provides application of nitidine chloride to the preparation of a medicament for resisting autoimmunity disease and graft versus host disease. An experiment shows that the nitidine chloride can inhibit the proliferation of human dendritic cells in vitro, inhibit the human dendritic cells from promoting the proliferation reaction of allogeneic T cells and strengthen the capacity of secreting interleukin 10 of the human dendritic cells. Meanwhile, in an experimental autoimmunity disease cerebrospinal meningitis model, when used in vivo, the nitidine chloride can reduce the average clinical score of a mouse and inhibit the spinal marrow infiltration degree of monocytes and can obviously improve the secretion level of the interleukin 10 in the blood serum of the mouse. In a heart transplantation experiment, when used in vivo, the nitidine chloride can prolong the survival time of the transplanted heart. In a delayed type hypersensitivity reaction model, when used in vivo, the nitidine chloride can reduce the ear swelling degree of the mouse. Both in-vivo and in-vitro results show that the nitidine chloride has a certain effect of resisting the autoimmunity disease and the graft versus host disease. The medicament is a preparation which consists of the nitidine chloride serving as an active ingredient and a pharmaceutical carrier. The medicament can be prepared into an oral preparation, an injection, a suppository or an external preparation and the like.
