Wistar rats (110-125 g) were irradiated with a single dose of 500 R. Histochemical studies were done concerning the glycoproteins (GP) of sublingual glands, gastric, small intestine and colon mucosa, and some intestinal enzymes: acid and alkaline phosphatase (ACP, ALP) leucineaminopeptidase (LAP), Mg-dependent ATP-ase, NADH-diaphorase, lactic dehydrogenase (LDH). After irradiation all these reactions were diminished, with a maximal effect between 3-5 days. This impairment is in accord with the maximal lethality in this interval after such a degree of irradiation that produced the gastrointestinal syndrome. Cocarboxylase, a radioprotector, improved these changes regarding the structures of the small intestine and also the GP of sublingual glands, stomach, small intestine and colon, demonstrating there its efficiency.

Vitamin B17 (VB17), also known as amygdalin and laetrile, is a type of carbohydrate occurring naturally in many plants, such as apricot kernels which have obtained a great interest in cancer therapy. This study aimed to investigate the hepatic protective potential of VB17 against Ehrlich ascites carcinoma (EAC)-bearing mice-induced liver injury, DNA damage, apoptotic P53, and PCNA alterations. A total of 100 female mice were divided into 5 groups (1st group, control group; 2nd group, VB17 group; 3rd group, EAC group; 4th group, pre-treated EAC with VB17; 5th group, co-treated EAC with VB17). Results showed that the presence of VB17 in pre-treated and co-treated groups lead to decreased DNA damage, microsomal protein, NADPH cytochrome c reductase, alpha-fetoprotein (AFP), AST, ALT, and ALP while showed increased cytochrome b5, cytochrome P450 amidopyrine N-demethylase, and aniline 4-hydroxylase compared with the EAC group. Many histopathological changes were observed in liver sections in EAC as moderate fibrosis and marked diffuse necrosis of hepatic tissue, marked inflammatory cells, and congested blood sinusoids. On the other hand, there was a moderate degree of improvement in hepatocytes in liver sections in pre-treated VB17+EAC, while a mild degree of improvement in hepatocytes, moderate cellular infiltrations, and moderate cytoplasmic vacuolization of hepatocytes in liver sections in co-treated EAC+VB17. In addition, there was a depletion in hepatic P53 and PCNA protein expression compared with the EAC group. It could be concluded that VB17 has a potential hepatoprotective effect against EAC cell-induced liver toxicity.
