Russian scientists have discovered the world's first evidence of artificial selection for a benign tumor. It is an aquarium goldfish, which are brought in China 1500 years ago. Some of them are amazingly beautiful species by red cap on his head. That it is particularly valued by collectors.What kind of education? How did they get there? For a long time it remained a mystery. But here is research professor of the St. Petersburg State University of Andrei Kozlov and MD Mark Zabezhinsky gave the answer to this question. They managed to prove that the cap - a benign tumor.
- We first described Read more [...]
Translated for the first time successfully tumor adult dogs, puppies MA Novinsky (1876). Since then, for the experimental study of tumors was used a number of different methods and research proceeded in a variety of ways. Currently, you can cause a wide variety of animal species O. and locations with different agents.
Transplantation of tumors. Distinguish auto-, iso-, homo-and geterotransplantatsiyu O.
Autotransplantation - transplantation O. same animal, which it originated, but in another place of his body - usually fails and can ensure the success of further transplantation to other animals. Read more [...]
Tsilindroma skin (Synonym: Turban tumor, tumor Shpiglera, gialinizirovannaya trihobazalioma, etc.) - a rare benign skin tumors, localized mainly on the scalp, at least on the face, trunk, and extremities. It occurs more often tsilindroma skin in women, often appears in childhood or adolescence, sometimes in families. Growing slowly for decades. Ulcerated tumors and metastases casuistically rare. Often solitary tumor in small painless nodes from 0.5 to 5.6 cm in diameter. Nodes dense elastic consistency, pale pink or dark red color with a smooth, hairless surface. Sometimes tumor multiple Read more [...]
Tsilindroma (from the Greek. Kylindros - cylinder) - A kind of epithelial tumor with a penchant for mestnodestruiruyuschemu growth, multiple relapses and malignancy. Correct to call this tumor tsilindromatoznoy adenoma or carcinoma. Should be distinguished from tsilindromy skin, which is always benign.
Tsilindroma occurs at any age, usually after age 40, and may be localized in the solid or soft palate, salivary glands, tongue, upper respiratory tract, orbit, evolving from muco-serous glands.
The tumor is usually single, has the form of gray-whitish or yellowish node dense consistency, clearly Read more [...]
Cytological diagnosis - a method of recognition under the microscope the cells, independently of ottorgshihsya tissue or artificially separated from them. In modern clinic to diagnose human diseases resort to cytology sputum smears from vaginal fluid, bronchial washings and gastric prints izyazvivshihsya mucous membranes and skin, as well as puncture of lymph nodes, spleen, liver, kidney, tumors and tumor formation in breast, thyroid and salivary glands, bone and soft tissue, using common for cytology (the study of cells) methods.
Preparations are prepared as thin smears, like blood spots, so Read more [...]
Adenoma (islet adenoma) of the pancreas to be surgical treatment, the more that the suspect tumor it may be malignant.
Apply enucleation of the tumor, resection of the tail part of the gland along with the tumor, and sometimes with the spleen, subtotal and total pancreatectomy. The operation was performed under endotracheal anesthesia with nitrous oxide, muscle relaxants. In 25-35% of cases of hyperinsulinism adenoma can not be found.
For small solitary adenoma tumor enucleate subcapsular or together with the capsule within healthy tissue. Sometimes the bottom of the tumor was excised with a Read more [...]
Chorionepithelioma - a malignant tumor formed from epithelial cells chorion after or during pregnancy in the uterus, occasionally in the fallopian tubes, cervix or ovaries. Chorionepithelioma usually formed in the placental site as a node, which grows in the uterus or in the thickness of its muscular layer of the peritoneum to cover, occasionally - in-stenochno without involvement of the endometrium. Microscopically chorionepithelioma has dramatically abnormal cells (such langhansovyh or syncytial). Chorionepithelioma destroys blood vessels soon spread to the lungs, brain, vagina, liver, and Read more [...]
Favourite localization of hemangiomas is the head and neck (50-80%). Most often angioma in children. Increasing in size, these tumors cause gradual atrophy of the soft tissues and bones of the facial skeleton, the displacement of neighboring organs in violation of their function. In addition, the wounded, the large hemangioma would create a risk of bleeding, infection, in some cases, possible malignancy them.
Many ways suggested for the treatment of tumors, suggests difficulties in the treatment of angiomas, and that many of these methods do not provide a complete and radical treatment. Thus, Read more [...]
Adenolymphoma are among the tumors, which are rare and range from 4 to 6% of all tumors of the salivary glands (VV Panikarovsky, 1965; FW Foote and E. Z. Frazell, 1953, and others). Name them due to the presence of two major components: parenchyma, usually represented racemose epithelial structures and stroma, consisting of typical lymphoid tissue. This kind of microscopic structure adenolimfom complicates the study of morphogenesis, which until now has remained controversial. Some authors (H. Albrecht and Z. Arzt, 1910; Q. Selfert and G. Geller, 1956) believe that adenolymphoma develop from Read more [...]
Upon questioning, the patient should pay attention to the nature and location of pain, their irradiation, particularly hematuria and pyuria, the injuries, occupational poisoning, congenital malformations, etc. A number of kidney disease occurs so characteristic that diagnosis can be made by history.
When viewed from the front wall of the abdomen is sometimes defined protrusion in hypochondrium by sharply increasing the kidney (with hydronephrosis, pyonephrosis, or cystic tumor). In advanced cases paranefrita can see diffuse swelling of the lumbar region, especially in the sitting position of the Read more [...]
Fibroid - a benign tumor of the connective tissue. Fibroma has a view of a round or oval, well delineated from the surrounding tissue. Distinguish solid fibroma, which is dominated by fibrous structures, and soft, with a predominance of the cellular elements (fibroblasts).
Tumor can occur at any age, with equal frequency in men and women. Localization fibroids varied: skin, subcutaneous and intermuscular cellulose, mediastinum, retroperitoneum, internal organs (uterus, gastrointestinal tract, etc.). Clinical manifestations depend on the location of the tumor. Fibroids grow slowly and can reach Read more [...]
Pheochromocytoma - hormonally active tumor medulla of the adrenal gland, consisting of chromaffin cells secreting adrenaline and adrenalin substance. Pheochromocytoma has the form of a rounded node, sometimes of considerable size, in the context of a yellowish-brown color with hemorrhages.
Clinical manifestations are due to excessive intake of catecholamines in the blood (see) allocated to tumor cells. Hyperfunction of the adrenal medulla in pheochromocytoma may be constant or intermittent, which causes a permanent or paroxysmal nature of hypertension.
Malignant pheochromocytoma are extremely Read more [...]
It is also assumed that the effectiveness of warfarin in the treatment of cancer is caused not only anticoagulant effect, but also a direct effect on tumor: Inhibition of cell divisions in it and improve its blood supply, oxygen delivery. Well-oxygenated tumor cells more sensitive to radiation treatment and chemotherapy. Furthermore, warfarin enhances the antitumor action 5-FU and other chemotherapeutic agents, slowing their inactivation and removal, as well as synchronizing tumor cells in the stages S and G1 cell cycle, when they are particularly sensitive to 5-fluorouracil. Thus, the therapeutic Read more [...]
Of the simple phenols antitumor activity was found in the main classes of the founders of phenols that are prone to oxidation to form semiquinones and quinones. This catechol, its oxidation products interact with the pyrimidine bases of DNA of tumor cells, causing alkylation of DNA and cell death. This is hydroquinone, which blocks the promotion of tumor cells by cell cycle stage G1. This pyrogallol and gallic acid derivatives.
Greater antitumor activity have quinones, especially actively react with nucleic acids and proteins of tumor cells and inhibit tumor growth. A number of methoxy and Read more [...]
Among the phenolic antibiotics owned and mycophenolic acid produced by mold fungus Penicillium stoloniferum. Used as the sodium salt. Characterized by low toxicity, relatively rapidly inactivated by the formation of pairs of compounds with glucuronic acid and excreted in urine. Treatment effect is small, so mycophenolic acid is usually used as part of combination chemotherapy in the treatment schemes mainly solid tumors.
Along with phenols having antitumor action, there are drugs that affect only individual manifestations of disease or tumor as a means of influencing the individual metabolic Read more [...]
The problem of cancer, malignant transformation of cells - one of the most complex and pressing problems of modern medicine. There are many different points of view on the nature of cancer, its causes and conditions. Coverage of this issue at least in general terms, beyond the scope of this book. But as soon as there are phenolic compounds of substances that contribute to cancer development and treatment of anti-cancer agents, touch on this issue only to the extent that is necessary for the understanding of the action of phenols.
The crucial difference of tumor cells from normal cells of the Read more [...]
