Spontaneous Lesions in Chinese Hamsters
Veterinary Pathology, 1977One hundred and fifty-seven Chinese hamsters ( Cricetulus griseus) from the Lovelace Foundation Inhalation Toxicology Research Institute colony had pulmonary granulomas, nodular hyperplasia of the liver, granulocytic bone marrow hyperplasias and myelogenous leukemia, nephrosclerosis and uterine adenocarcinomas. These Chinese hamsters had a median life

Rous Sarcoma in Chinese Hamsters
Science, 1964A variant of the Rous sarcoma virus induced tumors in newborn Chinese hamsters within 2 to 8 weeks. The tumors grew progressively and sometimes metastasized. They were successfully transplanted in series in Syrian hamsters. The chromosomes of the tumors in the Chinese hamsters as well as of those transplanted into the Syrian hamsters were Chinese ...

Feeding systems in Chinese hamsters
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1984Modulation of feeding by opiates, putative satiety peptides, and dopamine was explored in the Chinese hamster, an animal that develops diabetes mellitus in certain inbred strains. Diabetic hamsters were hyperphagic relative to their nondiabetic controls, but both groups exhibited natural circadian variation in feeding.

Ultrastructural study of the adenohypophysis of the Chinese hamster
Cells Tissues Organs, 1976The adenohypophysis of normal Chinese hamsters of both sexes was examined ultrastructurally. Organs were fixed by intravascular perfusion with S-collidine-buffered glutaraldehyde solution. Seven types of cells were differentiated and, according to morphological characteristics, classified as (1) mammotropes, with very large (400–800 nm) and ...

Cyclophosphamide treatment of prediabetic Chinese hamsters
Acta Physiologica Scandinavica, 1984To assess the immune system's involvement in the causation of diabetes in the genetically diabetic Chinese hamster, “prediabetic” animals were immunosuppressed with Cyclophosphamide, starting several weeks prior to the expected onset of hyperglycemia. The immunosuppressant dose was titrated to maximally depress the lymphocyte count without significant ...

Gametes and fertilization in the Chinese hamster
Gamete Research, 1983AbstractFreshly ovulated eggs are each surrounded by a compact cumulus oophorus. The overall diameter of the normal egg (including the zona pellucida) is about 100 μm. Cumulus cells, particularly those near the egg, are arranged redially in a viscous noncellular matrix. The spermatozoon is about 250 μm in length.

Cricetulus griseus (Chinese hamster) [PDF]
, 1967 The long arm of the X may show a weak secondary constriction at the distal third. However, without autoradiography with tritiated thymidine, the X may be indistinguishable from chromosomes No. 4. The Y chromosome is morphologically unique.

Distribution of DNA in Chinese hamster cells
Experimental Cell Research, 1967Abstract The distribution of DNA in the nucleus of Chinese hamster cells growing in vitro was studied by labeling DNA with tritiated thymidine before cutting 20–25 serial sections through the nucleus. Autoradiography and light microscopy were used to locate the distribution of label in each section.

Superovulation in immature and mature Chinese hamsters
Gamete Research, 1987AbstractMature female Chinese hamsters ovulate an average of 8.8 ± 1.0 (mean ± SD) eggs per female in each estrous cycle. Superovulation can be induced in both immature and mature females by subcutaneous or intraperitoneal injections of pregnant mare serum gonadotropin (PMSG) and either human chorionic gonadotropin (hCG) or pituitary luteinizing ...

PHOTODYNAMIC INACTIVATION OF CHINESE HAMSTER CELLS
Photochemistry and Photobiology, 1983Abstract— Visible light exposures have been shown to kill acriflavine bound Chinese hamster cells. Such killing was enhanced when (a) dye was present in the medium during irradiation and (b) the pH of the medium was 8.5, instead of the normal 7.5 during the exposure.
