Short term effect of 28-homobrassinolide on serum, liver and kidney marker enzymes and other biochemical parameters of male albino rats

Brassinosterols (BS) are ubiquitous pluripotent growth regulator present in plants. They exist in isoforms of epi and homobrassinolides (HB).  BS act as potent stimulators of root and shoot elongation, cell division, DNA and RNA polymerase activity, ethylene production and of stress tolerance to temperature, water scarcity and salinity in plants. It is also used to increase the yield of crop and to protect the plants against pesticides. Consumption of plant material as diet and used as growth regulator in animals, and application of BS in agriculture would increases its availability to the host tissues. In the present study, the effect of 28-HB, an isomer of brassinosterol on serum, liver and kidney marker enzymes, lipid peroxidation, tissue histology and the blood parameters of rat were investigated. The rats were given the compound by intradermal mode at the concentration of 75µg, 150µg and 300µg as single dose and the effects were observed after 4 hr to study the immediate response of the animal. The treatment of rats with 28-HB, caused different effects on the serum, liver and kidney parameters of this study. In conclusion, the present study showed that 28-HB affects the structure and function of rat tissues in a dose dependent manner.Keywords: Brassinosterols; homobrassinolides; 28-HB; lipid peroxidatio

Acute effect of gibberellic acid on serum enzymes and blood markers in male albino rats

This study was designed to evaluate the influence of a phytohormone, gibberellic acid (GA3) on marker enzymes and biomarkers of serum, and blood hemoglobin and its blood cells counts of rat. In order to evaluate the positive/negative effects, the rats were administered 75μg, 150μg and 300μg of GA3/kg body weight as a single dose. GA3 treatments produced differential effects on the different parameters at dose dependent manner after 4 hours.The down regulation in specific activities of ALT, ALP, GGT and amylase were noted against the control with significant up regulation of AST activity. GA3 also produced dose dependent effect on biomarkers. There is a substantial reduction in the quantity of glucose, urea, creatinine, calcium, phosphorus, sodium and potassium was recorded against the control. On the other hand, the insignificant increase in content of total protein, albumin and uric acid was observed at all dose of GA3 treatment against the control. GA3 increased the RBC, WBC and neutrophil by decreasing the lymphocyte total numbers. Platelets, monocytes and oesinophils count were not altered by any dose of GA3.In conclusion, GA3 produced dose dependent effect on different parameters of rat blood serum.Keywords: phytohormone; gibberellic acid; creatinine; neutrophi

Biochemical evaluation of low dose methyl 2-benzimidazole carbamate fungicide on male albino rats

Methyl 2-benzimidazole carbamate (carbendazim) is one of the synthetic fungicides that controlled organisms that caused plant diseases of different types. It is widely used as a preservative in leather, paint, textile, fruits and papermaking industry. It is also used as an anticancer drug in chemical medicine. In the present study low concentrations of carbendazim was administered at 5, 10, 25 and 50mM doses intradermally to male albino rats. At the end of 6 hr, 12hr and 24hr duration, blood samples were collected from the animal for the analysis of biochemical and haematological parameters. Carbendazim caused an increase of cholesterol, uric acid, glucose and creatinine while serum phosphorous content was decreased. However, mean hemoglobin, WBC, E, and platelet counts increased and total RBC, N and L counts decreased. These results indicated that low dose level carbendazim contributed to toxicological effects in the rat tissues.Keywords: Methyl 2-benzimidazole carbamate; Fungicide; Rat tissue
