There is a certain classification of types of microscopy, which is determined by different approaches in the studies.
The following varieties of microscopic examination are distinguished:
- multi-photon study;
- optical microscopy;
- laser version of microscopic examination;
- X-ray examination;
- electron microscopy.
All varieties of this research provide the most complete information.
What is a microscope, the video below will tell you:
Features of the
The application of a certain algorithm of actions that determine the high result is due to the chosen method of conducting a study using a microscope of any kind and design.It was developed once, and the high accuracy, as well as the informativeness of the data obtained, determined its continued use in carrying out this type of research.
Using microscopy can be detected, including such diseases like:
- epidemic pemphigus newborns,
- pemphigus vulgaris,
- otomycosis ear,
- candidiasis of the esophagus, etc.
Optical, luminescent, light, electronic and other types( methods) of microscopy are described below.
The most common method used for microscopy is to consider a light version of such a study.Its main characteristics are the following:
- sharpness of the resulting image;
- maximum information content of all processes within the material under study;
- simplicity of carrying out such research;
- possibility of correcting the initial data of the device to ensure the receipt of more information.
Light microscopy has a number of varieties that differ in the location and extent of the light beam, the direction and intensity of light.Luminescent, ultraviolet, infrared, contrast, dark and light field method - all these types of light tissue research are used in studying the structure of tissues and processes inside it.
Studies with the The expediency of using a device in medicine that has been known for a long time as a microscope is scientifically sound and very promising.After all, the continuous improvement of this tool for carrying out a variety of diagnostics makes it possible to study the living organism cell more and more carefully, which is the most informative material for obtaining an idea of the state of health and the prospects for therapeutic intervention.
The following techniques are considered the most informative when using microscopy:
- study of urine and its sediment;
- study of blood samples;
- study of the smear.
Each of these methods of conducting a microscopic study is a collection of specific actions that reveal the structure of the cells of the material under investigation, processes within the cells and, on the basis of the data obtained, makes it possible to make predictions and formulate treatment regimens.
As a microscopic mask is produced, the video below will tell the video below:
Since urine is the end product of kidney function, its study provides the most complete representation of both the work of these organs and the processes that occur in them.Urine cells can determine the presence in the kidney of current inflammatory processes, the presence of infections, fungi and other microflora, which is hazardous to health.
The urine is also judged by such indicators as its transparency, color, the presence of sediment, reactivity.In addition to the kidneys, urine contains information about the general condition of the body and blood.With the help of microscopy of urine, cystinuria, renal failure, and other nephrologic abnormalities are revealed.
Examination of blood samples under a microscope of cells allows specialists to get an idea of the current processes in the body.This becomes possible due to the analysis of the composition of cells, because in normal state and good health they contain a certain number of different components that fulfill a certain role: the leukocytes are designed to fight infectious cells that penetrate into the body, the red blood cells enrich all internal organs with oxygen.And with a change in their number, we can conclude about the changes occurring in the body.
With the help of a microscopic examination, it is possible to determine what is the effectiveness of the medication being administered.Next, microscopy of urogenital and other types of smear is described.
Smear in this study
Blood smear, also providing a significant amount of information, allows you to determine more accurately all the pathological processes in the body, the degree of their neglect.After all, blood, representing one of the most important environments of our body, contains complete information about it.
With the help of blood smear microscopy reveals such processes as the degree of blood coagulation, the maturity of leukocytes in it.And this allows us to get the most complete picture of the treatment, as well as chemotherapy and laser treatment.
The main parameters of the microscope for smear microscopy, urinalysis, feces, sputum and sputum are described below.
Basic parameters of the
Microscope application in medicine and biology is most justified.A large amount of information obtained with its help, relative ease of use makes it possible to obtain the most informative picture.The most indicative characteristics of any microscope should be considered resolution and contrast, which provide clarity of image and information.
- The resolution of the is determined by the degree of sharpness of the image of the two points closest to each other.The index of resolution of the human eye is 0.2 mm: two points located closer to this distance merge into one, which leads to failure in obtaining a common picture - instead of points of the eyes, another image is found.A microscope with a good resolution gives a complete picture of the location of all the constituent tissues, and also gives an increase of about 2000-3000 times.
- The brightness of makes it possible to reveal the shades of the tissues of the test sample, which gives information about the state of the organism, the processes in it.Modern microscopes have high brightness values, which makes microscopy the most informative method of investigation.
Importance of the
method The importance of a tissue research method such as microscopy can not be overemphasized.Its capabilities allow us to identify structural changes in cell tissues that can cause various diseases.Also, microscopic studies provide material to specialists for analysis of the treatment being conducted, and its effectiveness.
Various methods of microscopic research allow you to make the most complete picture of the state of health and the current process in the body, prevent the likelihood of recurrence of diseases.
