Accelerated Generation of Extra-Islet Insulin-Producing Cells in Diabetic Rats, Treated with Sodium Phthalhydrazide.

β-cells dysfunction plays an important role in the pathogenesis of type 2 diabetes (T2D), partially may be compensated by the generation of extra-islet insulin-producing cells (IPCs) in pancreatic acini and ducts. Pdx1 expression and inflammatory level are suggested to be involved in the generation of extra-islet IPCs, but the exact reasons and mechanisms of it are unclear. Macrophages are key inflammatory mediators in T2D.

Accelerated liver recovery after acute CCl poisoning in rats treated with sodium phthalhydrazide.

Pharmacotherapy of hepatobiliary disorders is an important issue due to the high prevalence of liver failure, toxic and viral hepatitis and cirrhosis. The number of stimuli that can potentially induce or accelerate liver recovery is limited; in our study we selected sodium phthalhydrazide, which has been found to promote liver regeneration after partial hepatectomy. We examined the effects of phthalhydrazide on liver morphometric, histological and biochemical parameters in rats intoxicated with CCl.

Recruitment of macrophages and bone marrow stem cells to regenerating liver promoted by sodium phthalhydrazide in mice.

Pharmacological interventions which could be hepatoprotective, depending on bioavailability, anti-inflammatory and macrophage-targeting potential of drugs, are still at early preclinical stages. Existing evidence from many animal models of liver injury, as well as from human data, indicate that pharmacological and/or phytochemical interventions have limited impact on liver recovery. Recent studies on stem cell therapies focused on different cell subsets involved in tissue repair, including monocytes/macrophages and bone marrow cells migrating to the injured liver.

Partial recovery from alloxan-induced diabetes by sodium phthalhydrazide in rats.

In the commonly used experimental model of diabetes, a cytotoxic glucose analogue alloxan can selectively destruct pancreatic β-cells, with characteristics similar to the type-1 diabetes (T1D) in humans. Treatment of diabetic rats with sodium phthalhydrazide partially reversed diabetogenic pathology in the alloxan-induced diabetes. The alloxan-treated rats with permanent hyperglycemia, which further received i.
