Hepatic Lipidosis Most common form of severe liver disease in cats. Most often seen in obese cats suddenly subjected to dietary deprivation. May also be associated with diabetes mellitus, drug injury and toxicity. Thedisease seems to result from the sudden mobilisation of the bodies fat stores which quickly overwhelms the liver's ability to process the raw fat into useful nutrients. The fat accumulates in the liver rapidly and causes acute liver failure. The end result is a swollen, greasy liver which is fragile and yellow to see. The cats present with complete lack of appetite and many signs of acute liver failure. Treatment is based on the provision of a highly nutritious diet to provide the energy required to run the body, stop the ongoing mobilisation of the fat stores, and drive the liver to decrease the fatty accumulation in the liver. Treatment is difficult and a long process.

L1210/0 cells are maintained in an exponential suspension culture at 37 ℃ in a humidified atmosphere of 5% CO 2 in McCoy's medium 5a (modified), supplemented with 15% calfserum, and Fungizone. L1210/0 cells are incubated in Cisplatin (7 μg/mL) for 2 hr at 37 ℃. To measure growth inhibition, the cells are centrifuged, washed once, resuspended in fresh medium at 30 × 10 3 to 50 × 10 3 cells/mL, and incubated for 3 days. Cell numbers are determined on a Coulter Counter. An aliquot of cells is diluted with an equal volume of % trypan blue. Viability is recorded as the percentage of cells that has excluded trypan blue. Cells incubated with Cisplatin as above are also diluted into % agar and allowed to grow for 2 weeks when colonies are counted.

HDL (high-density lipoprotein), or the "good" cholesterol, and LDL (low-density lipoprotein), or the "bad" cholesterol, are lipoproteins that carry cholesterol through the veins and arteries of the body. HDL and LDL combined, is your "total" blood cholesterol. The difference between the two are that high levels of the "good," or HDL cholesterol, may protect against narrowing of the blood vessels in the body, which protects you against heart attack, stroke, and other cardiovascular diseases. But high levels of LDL, or the "bad" cholesterol, may worsen the narrowing of the blood vessels in the body, which puts you at a greater risk of stroke, heart attack, and cardiovascular diseases, some of which are life threatening.

The Oogonia multiply by dividing mitotically; this proliferation ends when the oogonia enter meiosis. The amount of time that oogonia multiply by mitosis is not species specific. In the human fetus, cells undergoing mitosis are seen until the second and third trimester of pregnancy. [7] [8] After beginning the meiotic process, the oogonia (now called primary oocytes) can no longer replicate. Therefore, the total number of gametes is established at this time. Once the primary oocytes stop dividing the cells enter a prolonged ‘resting phase’. This ‘resting phase’ or dictyate stage can last anywhere up to fifty years in the human.
