Role of the alveolar macrophage in the induction of pulmonary phospholipidosis by chlorphentermine. I. Drug and phospholipid levels. 1986

C A Heyneman, and M J Reasor

In this study we have shown that the alveolar macrophage (AM) plays a major role in the induction of phospholipidosis in rat lung by chlorphentermine (CP). Rats were administered CP (30 mg/kg i.p., 5 days/week) for 1, 4 and 8 weeks and the levels of CP and total phospholipid were measured in whole lungs and in the AM fraction recovered from the lungs by pulmonary lavage. Lungs accumulate CP to a much greater extent than liver or kidney and show a marked increase in phospholipid content by 8 weeks. Drug treatment is accompanied by the recovery of an elevated number of AMs at all time points. The CP and phospholipid levels in AMs reach a peak at 4 weeks with little change beyond that time. Initially the phospholipidosis is localized largely in the AMs with the disorder developing in other compartments of the lungs with increasing treatment time. The AMs contribute 3% of the total pulmonary phospholipid in control rats. After 1 week of CP, 34% of the pulmonary phospholipid is in the AM fraction with this value being 21% after 8 weeks. The CP to phospholipid molar ratio is higher in AMs than whole lung at all three time points.

UI	MeSH Term	Description	Entries
D008064	Lipidoses	Conditions characterized by abnormal lipid deposition due to disturbance in lipid metabolism, such as hereditary diseases involving lysosomal enzymes required for lipid breakdown. They are classified either by the enzyme defect or by the type of lipid involved.	Lipidosis,Lipoidosis
D008171	Lung Diseases	Pathological processes involving any part of the LUNG.	Pulmonary Diseases,Disease, Pulmonary,Diseases, Pulmonary,Pulmonary Disease,Disease, Lung,Diseases, Lung,Lung Disease
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D008297	Male		Males
D010645	Phentermine	A central nervous system stimulant and sympathomimetic with actions and uses similar to those of DEXTROAMPHETAMINE. It has been used most frequently in the treatment of obesity.	Adipex-P,Duromine,Ionamine,Phentermine Hydrochloride,Adipex P,AdipexP,Hydrochloride, Phentermine
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.	Phosphatides,Phospholipid
D011650	Pulmonary Alveoli	Small polyhedral outpouchings along the walls of the alveolar sacs, alveolar ducts and terminal bronchioles through the walls of which gas exchange between alveolar air and pulmonary capillary blood takes place.	Alveoli, Pulmonary,Alveolus, Pulmonary,Pulmonary Alveolus
D002745	Chlorphentermine	A sympathomimetic agent that was formerly used as an anorectic. It has properties similar to those of DEXTROAMPHETAMINE. It has been implicated in lipid storage disorders and pulmonary hypertension. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1223)	Avipron,Chlorphentermine Hydrochloride,Desopimon,Pre-Sate,Hydrochloride, Chlorphentermine
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
