In the course of ultrastructural studies on the morphology of the pancreatic islets of various rodent species used in current diabetes research, intranuclear rod-shaped structures were observed in the $-cells of mice . Since there appeared to be no previous reports on the occurrence of such structures in endocrine pancreas of any species, it was thought worth while to pay some further attention...

Rodents belong to the order Rodentia, which consists of three families in Borneo (i.e., Muridae, Sciuridae and Hystricidae). These include rats, mice, squirrels, and porcupines.

Rodent repellents are chemicals which by taste or odour or possibly by both will prevent animal from feeding or gnawing. Such substances may be used in protecting an area from rodent infestation or in protecting packaged food, packing materials, electric cables, and other important vulnerable materials. Mature and healthy house rat, Rattus rattus of both sexes, was exposed to 5, 10, and 20% euc...

There are thousands of rodent species in the world. While they provide a number ecosystem functions, unfortunately, some cause significant damage to agriculture. Rodent occurs crops field, but also stored foods, livestock feed, and structures. many methods available reduce populations and/or damage, including both lethal non-lethal methods. advantages disadvantages most methods, regulated by fe...
