A morphological study of 23 cases of extra-nodal non-Hodgkin’s lyniphomas is presented. The disease was most prevalent in the second decade (30.4%), followed by fourth and fifth decades (26.1%) and seventh decade of life (13 .1%), respectively. The male: female ratio was 1.1:1. The commonest primary site of lymphoma was bones, followed by pharynx, skin and other organs. Histologically, accordin...

Acute myeloblastosis and several forms of tumor, including one case of lymphosarcoma occurred when avian myeloblastosis virus (BAI-A strain) was inoculated into newly hatched chicks (SPF). The homogenate of lymphosarcoma inoculated intraperitoneally into other newly hatched chicks induced a high incidence of erythroblastic leucosis. Electron microscopy did not reveal the presence of C-type viru...

The clinical and pathological features of two patients with chronic myeloid leukaemia who died from lymphosarcoma are described. Both had been treated with busulphan which, at the time of development of lymphosarcoma and at death, appeared to be controlling the leukaemia satisfactorily.

the c3 phenotypes were determined by high-voltage agarose gel electrophoreses in german patients suffering from lymphosarcoma (n=34), hodgkin (n=59) and a group of other haematological diseases (n=46). frequencies of c3 ss, sf and ff pho=enotypes were not significantly different from the frequencies found in a control group of 322 healthy germans. however, high frequency of the ff phenotype in ...

Sixty-nine sheep were infected with bovine leukemia virus from bovine lymphosarcoma materials. Twenty-four developed lymphosarcoma and died from 13 to 66 (average, 29) months later. Circulating lymphocytes were increased to leukemia levels (70,000 to 403,000/cu mm blood) in only eight sheep within 2 to 3 months of death. Various lymph nodes and visceral organs including heart, abomasum, uterus,...

Bovine lymphosarcoma cells were transplanted into six new born calves which had first received 200 rads of whole-body irradiation. Distinct subcutaneous masses, involving one or more prefemoral and/or prescapular lymph nodes, were evident within one or two weeks after inoculation of lymphosarcoma cell suspensions. In each instance, it was ]x>ssible to make a histologie diagnosis of lymphosarcom...
