In the chicken, serum gamma globulin (CGG) is preferentially transferred by the follicular epithelium of the ovary to the developing ova. The concentration of gamma globulin in the yolk of the unfertilized egg is many times the concentration of chicken serum albumin (CSA). This transfer occurs largely during the 4 to 5 days preceding ovulation when the growth of the ovum is most rapid. Thus, in...

background and aims: rotaviruses are one of the main causative agents of acute viral gastroenteritis in both young human and animals. several methods have been used for diagnosis of rotavirus infection. most of these methods are not easily available in iran. methods: in our study attempt was made to develop a method which could replace the commercially imported kit. rota virus was purified and ...

One of us (LWS) bad occasion to treat a young white man with gamma globulin for prophylaxis after exposure to infectious hepatitis. He was given two injections, 10 cc. each, of human Poliomyelitis Immune Globulin, one week apart. It was observed that shortly after the second injection, his severe pustular and indurated acne improved considerably. This observation led to the present study, of wh...

Antisera to normal 7S gamma-globulin and to Bence Jones proteins permit the grouping of myeloma proteins (gamma and beta 2A types), Bence Jones proteins, and the Waldenström type macroglobulins into two fundamental antigenic groups. The antigenic determinants responsible for this grouping are common to all these proteins which fall in the general category of immunoglobulins. Antisera to Bence J...

The researches initiated by Cecil, Nichols, and Stainsby (1931), Waaler (1940), and Rose, Ragan, Pearce, and Lipman (1949) on the agglutinating activity of serum from patients with rheumatoid arthritis led to the discovery of a serum factor, now regarded as characteristic of rheumatoid arthritis, and therefore designated "rheumatoid factor" (Pike, Sulkin, and Coggeshall, 1949; Svartz, 1956, 195...
