The present study examined the effect of water extract (200 mg/kg body weight) of Rosmarinus officinalis L. in streptozotocin (STZ)-induced diabetic rats for 21 days. The hepatoprotective effects were investigated in the liver tissues sections. There was a significant increase in serum liver biochemical parameters (aspartate aminotransferase, alanine transaminase, and alkaline phosphatase), accompanied by a significant decrease in the level of total protein and albumin in the STZ-induced rats when compared with that of the normal group. The high-dose treatment group (200 mg/kg body wt) significantly restored the elevated liver function enzymes near to normal. This study revealed that rosemary extracts exerted a hepatoprotective effect. The results indicate that the extract exhibits the protective effect on tissues and prove its potentials as an antidiabetic agent.

Investigation of functional hepatoprotective components from plants origin is a new model for drug evolution. The study examined the protective effects of Arabic gum (AG) induction on liver serum markers, antioxidant enzymes and lipid peroxidation in liver tissue against trichloroacetate (TCA) induced hepatotoxicity in male albino rats. Also, the chemical constituents and antioxidant assay of aqueous extract of AG was determined. TCA at the dose of 50 mg/kg for 2 months produced hepatotoxicity as examined by the significant increase of serum activities of ALT, AST, ALP and conjugated bilirubin level in the TCA treated animals alone and decrease in total protein and albumin levels. Pretreatment with AG aqueous extract (0.5 g/kg/day) significantly (P< 0.05) lowered the serum enzyme activities and increased in total proteins and albumin level. The antioxidant studies showed that the activities of hepatic SOD, CAT and GPx were decreased in TCA induced animals with significantly elevated in MDA content which is reversed in pretreatment with aqueous extract of AG. Histopathology of the liver sections confirmed that the AG extract ameliorated hepatic damage induced by TCA. In conclusion, the study demonstrated that AG supplementation for 2 months in TCA induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.

ALL is the most common form of childhood cancer. Sufferers are treated with chemotherapy, which is associated with the production of free radicals. The aim of this study was to investigate the oxidative stress markers and some antioxidants status among Acute Lymphoblastic Leukemia patients. This study included 40 children newly diagnosed ALL before chemotherapy (mean age, 8.2 ±2) compared to 20 healthy controls (mean age, 7.6 ±1.4). The same of 40 patients of ALL undergoing chemotherapy treatment for 3 months. Oxidative stress, blood antioxidants status, kidney and liver profiles were measured in all groups. Our results showed that Antioxidants levels and Hb were significant decreased in ALL patients (P < 0.05) compared to control group, then antioxidants levels were more significant decreasing after ALL patients undergoing chemotherapy. In contrast MDA, 8dG, leukocytes count and Lymphoblast were significant increased (P < 0.05) compared to control group. Also, Urea and creatinine levels were found no significant difference between different groups, there was mild increase after chemotherapy but not significant. On other hand, ALT and AST were found no significant difference between healthy control and ALL patients. But their levels were found statistically significant to be increased in ALL patients after chemotherapy compared to before chemotherapy. In. conclusion, there are possible link between decreased antioxidants and increased levels of cells alterations due to oxidative damage in ALL, and this appear to be associated with complications of treatment.

A total of 24 rats were divided into 4 groups: control, stress, extract alone, and stress + extract (n = 6 each), for total 21 days of treatment. The immobilization stress was induced in rats by putting them in 20 cm × 7 cm plastic tubes for 2 h/day for 21 days. Rats were postorally treated with Salvadora persica at a dose of 900 mg/kg body weight via intragastric intubations. At the end of the test period, hematological and biochemical parameters were determined in blood and serum samples with determination of vital organs weights. The vital organ weights were not significantly affected in stressed rats as compared to control rats. Compared to the control group, the stress treated group showed significances in several hematological parameters, including decreases in WBC, RBC, and PLT counts. Furthermore, in comparison to the control group, the stress group showed significantly increased blood glucose, serum total cholesterol, LDL-cholesterol, and triacylglycerols levels and decreased HDL-cholesterol level. The hematological and biochemical parameters in the stress + extract treated group were approximately similar to control group. The SP extract restored the changes observed following stress treatment.
