Topic: Lipoma - 2 hours. Objectives of the topic: To train students in macroscopic and microscopic manifestations of lipoma Visual equipment and instruments: Organ, microtome, block window box hematoxylin, eosin. Alcohol, xylene, paraffin, microscopy, histological specimen No. 32 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. Benign tumors develop in all tissues. They are growing exponentially. Does not metastasize and relapse. Parenchymal cells are similar to native tissue. Lipoma is a mature tumor that develops from adipose tissue. Serum membranes and subcutaneous kletchatkasida, gastrointestinal tract. Tugunchasimon structure. Lipomas in cows 27 kg. maybe up to. Soft and hard lipomas are different. Lipo dystrophic and necrotic changes. Lipoma adipose tissue tumor group. Most domestic animals. Difference between soft and hard lipomas. Hemotoxylin - eosin and water - is studied by staining with dyes III. When stained with hemotoxylin-eosin dye, we see that the lipoma parenchyma is composed of fat particles. According to adipose fat cells, the nucleus is located at the edge of the cell, the cell is about the boundary between the st about the directory, connective tissue and blood vessels. And a lot of connective tissue fibers. In a large mirror, we focus on the structure of fat cells. The cells are of different sizes, ugly, the cytoplasm is empty, colorless. In the stroma we see fibrous, sometimes mucoid, mucous connective tissue. In the stroma, bone tissue is formed as a result of calcium salts. Droplets, reddish droplets of fat appear in Sudan III-stained fat cells. Lipoma occurs in horses with a hard consistency in the form of nodules, in dogs, in dogs. Omentum, subcutaneous kletchatkasida of cattle horses and Charvis passage. Macroscopic view. This tumor is benign beige, soft or hard konsistensiyalidir. There will be another hardness
Topic: Fibroma - 2 hours Objectives of the topic: To teach students the macroscopic and microscopic manifestations of tumors using the example of skeletal muscles and kidneys. Visual equipment and instruments: Organ, microtome, block window box, hematoksilin, eosin. Alcohol, xylene, paraffin, microscopy, histological specimen No. 2.1 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. Benigntumors develop in all tissues. They are growing exponentially. Doesn't it metastasize and relapse? The parenchyma of mature ho'jayralardan is similar to native tissue. Fibrous - mature tumor cells are formed in the fibrous connective tissue of mammals and birds, especially in the interstitial tissue. Stroma and parenchyma, depending on the ratio of hard and soft fibroma differences. Fibroma forms soft, ranging from the size of a millet grain, diameter 1 m. Fibroblast under a microscope, like the cells of fibroitlargi urchuksimon. Condensed cell core, glossy appearance. Cells throughout the g specific collagen fiber. A fibroma is an example of a histoid tumor consisting of fibrous connective tissue. Monuments, consistency, depending on soft and hard fibroids were divided. Macroscopic view. These tumors are gray in color, soft and hard to onsistensiyalidir. There will be a different hardness there. These tumors subcutaneously kletchatkasida heart, many uterus. Stromal fibroids vary depending on the relative lack of parenchyma. Microscopic view. Small soft fibromaning mirror connective tissue structure in the form of irregular cells, blood vessels. In a large speculum, fibroblasts and lymphoid cells are visible. Some cells have many fibers of arrangement between them. An increase in capillary blood vessels, in the endothelial cells of the capillaries and swollen as a result, these roads are closed. It is similar to a tissue tumor to normal connective tissue, with a single number of collogen fibers, fiber girth and age, blood vessels and connective tissue cells are different from normal tissues, Adenoma is a benign tumor that occurs only in the glands. Pancreatic adenomas have incisions. Epidermal carcinomas occur on the skin. A tumor develops in the thymus. Cell hyperplasia leads to the formation of tumor cells. The proliferation process also causes the formation of tumors.
