Studies on the Incidence and Inheritability of Spontaneous Tumors in Mice
نویسنده
چکیده
Throughout the animal kingdom the solid ovarian tumors seem to be infrequent, as they also are, relatively, among human tumors. Cystic tumors are described occasionally, but apparently less frequently in the lower animals than in man. Even among dogs, with their high incidence of tumor growth, ovarian tumors are rare according to the evidence furnished by literature dealing with canine neoplasms.1 In Sticker’s (2) compilation of tumors in domestic animals, of 766 tumors in dogs but 3 were in the ovary. As to other animals of Sticker’s series, in 509 cases of tumors in horses, 4 were in the ovary; of 110 in cattle, 6 were ovarian; there was 1 ovarian tumor among 23 tumors in cats, and none at all among sheep, goats, and swine. Kimura (3) has reported 142 cases of tumors in horses, among which were no ovarian tumors, although there were 49 in the testicle. Other evidence supports the figures of Sticker in indicating that cows have ovarian tumors more often than other species. Trotter (4) reported 305 bovine tumors observed in the Glasgow slaughter house, of which 5 were in the ovary (4 carcinomas and

Primary Spontaneous Tumors of the Testicle and Seminal Vesicle Ik Mice and Other Animals Xii, Studies in the Incidence and Inheritability of Spontaneous Tumors in Mice
Tumors of the testicle would seem to be uncommon in mice, for we have been unable to find even a single case reported in the literature, although they have been described in other species of lower animals. Thus, among 103 primary tumors observed by McCoy (1) among 100,000 rats killed in plague work, there was one described as an “angiosarcoma” of the testicle, without further details. Other ser...

Despite a lot of research, the etiology and progression of breast cancer remain incompletely understood. Recently, human cytomegalovirus (HCMV) was reported as a risk factor for breast cancer. The aim of this study was to know whether breast cancer could be caused by cytomegalovirus or not? In this experiment seventeen samples of RAZI/A mice with spontaneous breast cancer were being gathered fr...

EFFECT OF IRON OVERLOAD ON 7, 12-DIMETHYLBENZ (A) ANTHRACENE-INDUCED SKIN TUMORIGENESIS
Iron overload is known to occur in the West European and American population due to the consumption of iron-rich diets. On the other hand, genetic disorders leading to iron overload are also known. Iron overload leads to increased peroxidation and disruptive disintegration of lipid-rich membranes, and predisposes humans for an enhanced risk of cancer induction. In experimental animals iron ...
