Subject:Purulent nephritis- 2 hours.

Objectives of the topic: To teach students the macroscopic and microscopic manifestations of inflammation, such as the kidneys. Visual equipment and instruments: Organ, microtome, block window box, hematoksilin, eosin. Alcohol, xylene, paraffin, microscopy, histological specimen No. 70 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. -Inflammasio inflammation in Latin means fire. What calls for an inflammatory disease, which leads to the body tissue and blood vessels of complex reactions from the most injured tissue areas from metabolic processes in tissues, dystrophic (alterasiya), cell proliferation (proliferasiya) local blood circulation disorders (exudate and emigrasiya) based on the process said . Purulent inflammation of the blood vessels with liquid whey is characterized by a large amount of floating leykositlarning. Leykositlar vessel leaked out grain, fat and glycogen after the changes were completed, and then disintegrated. Streptococci, staphylococci and Escherichia coli play a very important role in the etiology of purulent inflammation. The following types of purulent inflammation are distinguished: - purulent catarrh - pus and mucus, the mucous membrane consists of massive exudate - purulent serous - serumal purulent inflammation from natural cavities of pus accumulation - this is characterized by empiyema - spread of phlegmon - purulent inflammation from the subcutaneous kletchatkalarning serum - fibrinli it is characterized by inflammation, necrosis, pus and tissue decay - Absess - purulent inflammation, characterized on special screens to be sure. Purulent nephritis kidney gemotogen path of purulent microorganisms due to stroke. Purulent endometritis, mastitis. Malpigiy to'plamchalaridan microorganisms will be bent tubules and an abscess is formed. While in epithelial cells there is dystrophy and necrosis. Macroscopic view. Enlarged to the size of the kidneys. The bark and main floors are grey. The consistency of the buds is loose. The kidney is a gray stream, and under its shell we see formations of different sizes filled with pus. They opened the membrane, the pus flowing. Microscopic view. Using a small microscope mirror, we focus on the curved tubules and Malpighian fascicles. Most tubules and malpigiy to'plpmchalari bluish spots around the blood vessels. A large microscope mirror will spot the polymorphic nucleus leykositlardan, then the number of blood cells and serum fluid composition. The purulent ekssudatningasosiy structure consists of leykositlardan gemotoksilin coloring them blue - violet.
