Lepra Cells Derived From

Gerhardt armauer hansen 1841 1912 discovered the acid alcoholresistant rods in lepra cells as the leprosy bacillus.

Lepra cells derived from. Jean oliver from the department of pathology of stanford university medical school san francisco. Foam cells are fat laden m2 macrophages containing low density lipoproteins. They are named because the lipoproteins give the cell a foamy appearance.

They can only be truly detected by examining a fatty plaque under a microscope after it is removed from the body. By means of the method of vital staining it is found that the lepra cell in rat leprosy is derived from the histiocyte. Foam cells also called lipid laden macrophages are a type of cell that contain cholesterol.

Infection can lead to damage of the nerves respiratory tract skin and eyes. This indicates a powerful phagocytic action oi the lepra cells such as is possessed by histioblasts and it is suggested that the lepra cells are derived from those of the sebaceous and sweat glands of the affected skin l. From the similarity in morphology and function of the lepra cells in this condition and those of human leprosy it seems likely that derivation of the cells in the two conditions is similar.

This nerve damage may result in a lack of ability to feel pain which can lead to the loss of parts of a persons extremities from repeated injuries or infection due to unnoticed wounds. These can form a plaque that can lead to atherosclerosis and trigger heart attacks and stroke. By means of the method of vital staining it is found that the lepra cell in rat leprosy is derived from the histiocyte.

The origin of the lepra cell jean oliver. Search for other works by this author on. By means of the method of vital staining it is found that the lepra cell in rat leprosy is derived from the histiocyte.

From the similarity in morphology and function of the lepra cells in this condition and those of human leprosy it seems likely that derivation of the cells in the two conditions is similar. The cells used by most of the companies now trying to find a covid 19 treatment called the 293t line were derived from the kidney tissue of a fetus aborted in the 1970s. It is a chronic communicable disease characterized by the production of granulomatous lesions of the skin mucous membranes and peripheral nervous system.

Similar pathologic cell forms were described later by rudolf ludwig karl virchow 1821 1902 17 and albert ludwig sigesmund neisser 1855 1916. From the similarity in morphology and function of the lepra cells in this condition and those of human leprosy it seems likely that derivation of the cells in the two conditions is similar.
