The value of cell proliferation and angiogenesis in the prognostic assessment of ovarian granulosa cell tumors.

Objectives: Most cases of granulosa cell tumors (GCT) of the ovary are characterized by a relatively good outcome. However, some tumors behave aggressively and some tend to recur many years after the initial diagnosis. Tumor growth depends on cell proliferation and angiogenesis.

The life-shortening effect of reduced physical activity is abolished by a fat rich diet.

In female mice on a control diet (3.6% fat) reduced physical activity leads to a reduction of the average life span. So the average age at death of an inactive group is 500 +/- 166 compared to 565 +/- 175 days in an active control group.

A glucose-rich diet shortens longevity of mice.

High plasma levels of glucose and insulin over long-time periods play an important role in the genesis of diabetic complications. There is evidence that the long term consumption of glucose-rich diet by rats is detrimental to insulin sensitivity. We investigated the effect of a glucose-rich diet on longevity of 70 female mice which were compared to 70 mice on a control diet.

Systemic application of cysteine-2:1-crotonal adduct for pharmacokinetic studies of tumor models in rats and mice.

A selective cytostatic effect is demonstrated for systemic application of the Michael adduct of crotonal (CAS 4170-30-3) with cysteine (CAS 52-90-4). As in earlier studies, our initial model was the Ehrlich ascites tumor (EAT) in mouse. Tablets containing 150 mg of the substance were implanted subcutaneously.
