Natural antioxidant products play a vital role in the treatment and prevention of cancer disease because they have no side effects. This study aimed to compare the chemoprotective effect of Spirulina platensis (SP) and garlic against hepatocellular carcinoma (HCC) in rats. This study was being done by using 60 male Wistar rats and divided into four groups. Group (I): normal group. Group (II): HCC group induced by injection of a single dose of DEN (200 mg/kg/I.P) and after 14 days injected CCl4 (1 mg/kg/I.P) 3 times/week/six weeks. Group (III): HCC group received SP orally at a dose (500 mg/kg). Group (IV): HCC group received garlic (250 mg/kg) orally. The results revealed that the Spirulina and garlic treatment have a significant decrease in Glutamate pyruvate transaminase, Glutamate oxaloacetate transaminase, GGT, LDH, and the Malondialdehyde (MDA) activity, and furthermore, a significant increase in the total protein level, the superoxide dismutase (SOD), and Catalase (CAT) activity nearly to normal activity. Furthermore, the hepatic expression of tumor necrosis factor (TNF-α), interleukin-6 (IL-6), inducible nitric oxide synthase, transforming growth factor-beta (TGF-β1), Heat Shock Protein glycoprotein 96 (HSPgp96), and Glypican 3 (GP3) were down regulated by the Spirulina and garlic treatment in comparison with those in HCC group. All findings reported that the chemoprotective of both Spirulina and garlic that have nearly the same effect may be due to antioxidant activity and inhibition of lipid peroxidation, amelioration of pro-inflammatory cytokine, HSPgp96, and GP3.

This study was planned to clarify the biochemical effects of the ginger on CCl4-induced acute hepatotoxicity and its comparison with garlic and combination between ginger and garlic through the determination of the following parameters in the blood and liver tissues of albino rats liver function test. The effect of ginger and garlic against CCL4 was estimated by using white albino rats (150-200 g), which divided into 5 groups of 15 rats. The result showed that CCl4 increase GGT, AST and ALT enzymatic activities, while rats received ginger and / or garlic, their liver function parameters were restored to normal levels and the best result was that group received ginger and garlic after CCL4 injection.
