The raport focuses on investigation of a sample of old people, mainly in their eighties, as against a control group of healthy subjects, aged between 25 and 40. In order to investigate the immunologic response the research has been carried on along the following lines. to show self Ab antinuclear (AAN), antimitochondrial (AM) and antismoth muscle (ASM), by using indirect immunofluorescence; to study alteration of serum immunoglobulins by using IDR; to study alteration of serum concentration of C3 fraction in the complement by using IDR; to determine immune complexes by using Haskova method; to investigate IR through R rosetting method. Immunologic reactivity (IR) disturbance was found, with respect to alteration of immunoglobulin ratio IgA, IgG, IgM vere slightly diminished. Self antibodies were present to a percentage of 17% as predominant of ASM, AM and AAN in decreasing order. Increase in C3 associated with increase in immune complexes could account for high incidence of cardio-vascular complications. Decline in IR is shown through the decrease in T lymphocytes where Ts is more markedly decreased as against decreased Ts. The results imbalance between stimulating activated cells and suppressive controlling cells. IR alteration could account for degenerative pathology in the subjects, namely, ATS, cardiovascular diseases, senility, pseudobulb syndrome, schizoaffective psychosis.

UI MeSH Term Description Entries
D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074 Immunoglobulin G The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B. Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D008297 Male Males
D001798 Blood Proteins Proteins that are present in blood serum, including SERUM ALBUMIN; BLOOD COAGULATION FACTORS; and many other types of proteins.

D002097 C-Reactive Protein A plasma protein that circulates in increased amounts during inflammation and after tissue damage. C-Reactive Protein measured by more sensitive methods often for coronary heart disease risk assessment is referred to as High Sensitivity C-Reactive Protein (hs-CRP). High Sensitivity C-Reactive Protein,hs-CRP,hsCRP,C Reactive Protein,High Sensitivity C Reactive Protein
D003176 Complement C3 A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.

D005260 Female Females
D005719 gamma-Globulins Serum globulins that migrate to the gamma region (most positively charged) upon ELECTROPHORESIS. At one time, gamma-globulins came to be used as a synonym for immunoglobulins since most immunoglobulins are gamma globulins and conversely most gamma globulins are immunoglobulins. But since some immunoglobulins exhibit an alpha or beta electrophoretic mobility, that usage is in decline. gamma-Globulin,gamma Globulin,gamma Globulins
