The natural tear film has mechanical, optical, antimicrobial and nutritional properties. Tear film components, such as EGF, fibronectin and vitamin A, play a vital role in the proliferation, migration and differentiation of the corneal and conjunctival epithelium. In ocular surface disease, such as severe dry eye, the epithelia may be depleted of these nutritional factors. Replacing the aqueous...

We have measured the effect of age on the rate of outgrowth of cells from human trabecular bone, using a quantitative dye-binding technique. In cultures supplemented with autologous serum, there were significant negative correlations between the age of the donor and both the proportion of fragments from which outgrowths were seen after 7 days (r = -0.70; p < 0.001) and the total cell number aft...

diced rib cartilage is an acceptable option in severe nasal deformities. we present our preliminary experience in kamc in nasal septoplasties using the autologous diced costal cartilage. this is a retrospective study of the 22 cases who needed the autologous diced costal cartilage in our centre in 4 years. all our patients needed autologous diced rib cartilages. twelve were wrapped with tempora...

Analysis of the humoral immune response of patients with melanoma has identified a small group of individuals with antibody to cell surface antigens that are restricted to autologous melanoma cells. These antigens, referred to as Class I or unique tumor antigens, are demonstrated by reactions between serum and cultured melanoma cells from the same patient and absorption tests with autologous an...

A 5 1/2-year-old girl, with a life-long history of recurrent staphylococcal infections and eczematous dermatitis had a defect in polymorphonuclear leucocyte chemotaxis and phagocytosis in autologous serum, a high serum IgE level, and a disturbed T cell function. Levamisole improved all the immunological abnormalities and there was a dramatic clinical improvement. Discontinuation of therapy with...

Leukemia associated antigen (LAA) was prepared from leukemia cells, using hypotonic lysis and low frequency sonications, followed by diethylaminoethyl (DEAE) cellulose column chromatography. Four protein peaks were eluted by stepwise introduction of increased concentration of NaCl solutions. With running on polyacrylamide gel electrophoresis (PAGE), unique bands which were not present in extrac...
