Opis:
Although vitamin D is included in the group of fat-soluble vitamins, it must be considered as a prohormone. Its active forms, including calcitriol, have pleiotropic effects and play an important role in the regulation of cell proliferation, differentiation and apoptosis, as well as in hormone secretion, and they demonstrate anti-cancer properties. Since calcitriol delivery can be beneficial for the organism, and Syrian golden hamsters represent a unique experimental model, we decided to investigate its toxicity in this species. In this study, we injected calcitriol intraperitoneally at doses 0 (control), 0.180±0.009 µg/kg and 0.717±0.032 µg/kg. Animal behavior was observed for 72 hrs after injection, and afterwards blood, liver and kidneys were collected for post-mortem examination, electron microscopy, and hematology analyses. The highest dose of calcitriol induced a change in animal behavior from calm to aggressive, and the liver surface showed morphological signs of damage. Following injection of calcitriol, ultrastructural changes were also observed in the liver and kidneys, e.g. vacuolization and increased number of mitochondria. There was also a trend for increased serum levels of aspartate aminotransferase (AST), but not of alanine aminotransferase (ALT) or GGTP (gamma-glutamyl transpeptidase). There was no change in Ca, Mg and P levels, as well as in blood morphology between experimental and control groups. These results indicate that calcitriol at 0.717, but not at 0.180 µg/kg, may induce acute damage to the liver and kidneys, without inducing calcemia. We propose that the hepatotoxic effect of calcitriol in hamster constitutes the primary cause of behavioral changes.

Opis:
The leaf extract of mulberry, Morus alba (L) in ethanol was used to treat the 7,12-dimethylbenz-anthracene (DMBA) - induced carcinoma in the buccal pouch of Syrian hamster, Mesocricetus auratus (L). The 0.5 percent DMBA in liquid paraffin was used for painting the buccal pouch. The DMBA treatment was carried thrice a week for 14 weeks. This was resulted into squamous cell carcinoma. The parameters analyzed include: The tumor incidence, volume and burden. It was followed by oral treatment with ethanolic extractives of mulberry leaves (TpEt) at a dosage of 300 mg/kg, body weight, to DMBA (on alternate days for 14 weeks)- painted animals. Administration of ethanolic extractive of mulberry leaves was found preventing significantly the incidence, volume and burden of the buccal pouch carcinoma. The ethanolic extractive of mulberry leaves exhibited significant effect, especially, the antilipidperoxidation and antioxidative enhancement in DMBA individuals of Syrian hamsters. The results are demonstrating the potency of ethanolic extractive of mulberry leaves for chemoprevention and significant antilipidperoxidative influence in 7,12-dimethylbenz-anthracene (DMBA)- induced carcinoma in the buccal pouch of Syrian hamster, Mesocricetus auratus (L). The activation of caspase through release of cytochrome C through disruption of mitochondrial membrane potential may be the sequence of action of the active principles of mulberry leaf extractives. With it’s bioactive compounds, mulberry, Morus alba (L) may open a new avenue in the cancer prevention and treatment. Taken together, the present attempt provide experimental evidence that leaves of mulberry may have chemopreventive effects on cancerous growth. Mulberry, Morus alba (L) may provide a therapeutic option for controlling the growth of cancer cells.
