Topic: Skin cancer - 2 hours. Objectives of the topic: To teach students the macroscopic and microscopic manifestations of a tumor using the example of skin. Visual equipment and instruments Organ, microtome, block window box hemotoxylin, eosin. Alcohol, xylene, paraffin, microscopy, histological specimen No. 35 and museum preparations Purpose of the lesson: Study of microscopic and macroscopic appearance. 1. Working pieces of pathological material will be cut from the kidneys and skeletal muscles. 2. The particles are washed and dehydrated in an alcohol battery. 3. Paraffin blocks are made. 4. Paint normal cuts. 5. Sections are stained with hematoxylin and eosin dyes. 6. Macroscopic changes are studied using museum preparations. Lesson content. Malignant tumor. They are infiltrative growth, metastasis and resedivation. Immature aging parenchyma, in marked contrast to native aging tissue. Caused by an atypical or non-specific increase in tumor tissue in the body. - the science that studies cancerous tumors is called. Tumors are based on irregular, non-hollow cell division. This division does not obey the body, tissues and leads to destruction and atrophy of surrounding tissues. Tumor cells to other cells of the body differ from specific morphological and functional disorders. Early tumors in dogs, cats, cattle, animals, pigs, chickens, sheep and goats. The reason is not fully understood. Currently, physical, chemical, viral, dizontogenetik and the prototype of the theory of polietiologik. Thriving of cancerous epithelial tissue in poor or immature cell tumors. Occurs in the skin, mucous membranes and parenchymal cells of epithelial organs. Depending on the cell type, epithelial carcinoma, squamous cell, columnar cell carcinoma is divided. Squamous cell carcinoma, in turn, shoxlanuvchi and shoxlanmaydigan are separated by raklarga. Depending on the ratio of parenchyma and stroma, it will be divided into soft (brain) and hard (skirry) groups. Morphology of the tumor. The emergence of a variety of species from tumors. They are round, the surface can be smooth, or clumsy asked. The cut surfaces of some tumors may be as fibrous as others. The color of the tumor depends on the type of tissue, as well as the richness of the veins. Konsistensiyasi tumor cells, Stromag level of development, depending on the type of vessels. For example: chondroma - hard, lipoma, myxoma, adenoma - soft. About lchovi microscopic tumors can be several tens of kg in size. For example, these cows are known to have 170 kg of ovarian tumors. The structure of all cancerous tumors is in two parts. The parenchyma consists of immature epithelial cells. the stroma consists of connective tissue. Microscopic view. In a small mirror, cells colored blue are visible. Jack Postal substance - in the center on the red cells around on the floor. In a large mirror, unstructured matter is visible in the center of the cell. Epithelial cells in the layer surrounding them, in their cytoplasm they are branched in a fashion - reddish in color, the cell is enlarged. Jack salt is located within the connective tissue of the stroma that you want. The stroma is inflamed, causing redness, la and leykositlarning to'plamchalari. These jacks, stromas, jarohatlashishi country
Subject:Topic: Leukemia - 2 hours. Objectives of the topic: To teach students the macroscopic and microscopic manifestations of leukemia. Visual equipment and instruments: Organ, microtome, block window box, hematoksilin, eosin. Alcohol, xylene, paraffin, microscopy, histological specimen No. 17 and museum preparations Purpose of the lesson: Study of microscopic and macroscopic appearance. 1. Working pieces of pathological material will be cut from the kidneys and skeletal muscles. 2. The particles are washed and dehydrated in an alcohol battery. 3. Paraffin blocks are made. 4. Paint normal cuts. 5. Sections are stained with hematoxylin and eosin dyes. 6. Macroscopic changes are studied using museum preparations. Leukemia - blood - the formation of organs and tumors is characterized by a certain smoothing process. In this case, division of immature blood cells is observed in various organs and tissues. In most cases, the growth of immature blood cells in the blood of leukemia is characterized by the disease. Initially leukemia giperplaziya mode, then giperplastik tumor mode, but now the growth of blood vessels - the formation of organs and organs, a typical example as a decrease in resistance. The first or primary processes of leukemia, bone marrow, spleen and lymph nodes. Milk or Q Ali children, but HW menu. Types of leukemia. 1. lymphocytic leukemia lymph node l bee, spleen injury x atlas. 2. myeloid leukemia - bone marrow injury tlanadi. 3. Low R I, or may be available from Gemona sec itoblastozlar. This variation (classification) is similar to Virchow's variation (1845). 1. Lymphosarcomalar - very well accelerates the development of certain lymph nodes. 2. Ret i kulosarcomas - cells resemble reticular cells. 3. Lymphographnulomatoses. There are 3 types of leukemia in birds. 1. Limfoleukoz 2. Myeloid leukemia 3. Eritroleukemia View the cages depending on the lower parliamentary h Varieties: 1. Leykomik leukemia - 12, 14, +16000 leykositlarda assessments of leukemia. Can reach 40,100, 300 thousand. Leukemia has already been known to science for 180 years. In 1801, the French scientist Bichat was the first to mention an expansion in the spleen, in the white blood. Acquisitions are more difficult for leukemia blood, and fogs. Limfostazlarda through lymph tomrilarining automatically after closure due to edema.2. S ubleykomik - up to 16 thousand leukocytes 3. leukomic - no leukocytes. After Virxovdan o l i m sec 70 species of Lucid (in the root klassifikasiya) proposals more than Virchnow to accept the proposal of the majority. Q on d View law enforcement agencies may not change, but the point is that the increase in white blood cells. Causes of leukemia, h IQ from 20 O rtiq theory this is explained Some of them have been processed about k let's see:1. R Adia s theory of ions - part of radiation (X-rays and other rays, due to influence). 2. Chemical secular or carcinogenic - 500 chemicals -Which leukemia (SPC) about 'HW to find out. 3. Viral theory - the virus is isolated from leukemia in poultry, cats, dogs, and guinea pigs. When these viruses entered the body, leukemia did not develop. But in laboratory animals, the immune reduction of bo'lgan.200xil disease symptoms is forced to see viral cells as property rights. 4. viral-genetic theory - the theory of academic Zelva - the virus is a nucleic acid in the cells of the line by name. The virus will participate in Ban Tmaidy. 5. MUTA s ion theory - mutant cells, cell Immunogen injury x Atlas and cell division. 6. Poli e theologians theory - the development mechanism was the development of leukemia, fetal blood is sure of the list of human development. It then develops in the bone marrow. Then, using the SE organs (heart, liver, skin, uterus), the white d is divided into cells. Clinical to about “look at the enlarged lymph nodes, to about” the orbit around white t leukemia Moderator arrow o 'cultivate. T OG ' settings through the intestinal walls of the womb to increase divorce, monitoring fat onlashganini feelings. Enlarged lymph nodes, myeloid leukemia develops hemorrhage. Enlarged spleen (m, 1 yen up to 40 cm in length) In the intestines and spleen - the lymphatic system is damaged, enlarged, the wall of the spleen is thickened. Shirdon, leukemic tissue is grown on those intestinal walls. 2 cm thick, muscular layer of the heart wall, light gray in color. The walls of the uterus, bladder tissue in the development of leukemia.
