ABSTRACT: Introduction & Objective: Diabetes mellitus is a common disease in human societies. Proteins non-enzymatic glycation has deleterious effects on the structure and function of proteins. Non-enzymatic glycosylation of proteins can be involved in the pathogenesis of diabetic complications such as retinopathy and nephropathy. One way of preventing this reaction is the use of medicinal plants. Chamomile, clove and garlic are herbs which their alkaloid compounds have antioxidant property. The aim of this study was to evaluate the effect of chamomile, clove and garlic extract on non-enzymatic glycosylation of albumin. Materials & Methods: In this experimental study, hydroalcoholic extract of chamomile, clove and garlic was prepared. In vitro albumin glycosylation reaction was carried out in presence of different concentrations (0.01, 0.05 and 0.1 g/L) of chamomile, clove and garlic extracts and level of glycosylated albumin was measured. Non-enzymatic glycosylation of albumin was determined by nitrobluetetrazuliom method. Absorbance changes were measured in 530 nm by Eppendorf spectrophotometer. Results: In this study, chamomile extract in 0.01, 0.05 and 0.1 g/L of its concentrations had respectively 9%, 17% and 26%, inhibitory effect on albumin glycosylation. Albumin glycosylation reaction was inhibited 23% by 0.01 g/L concentration of clove and garlic extracts and the level of inhibition of albumin glycosylation decreased by increasing of extracts concentration. Chamomile extract with 0.1 g/L concentration has the most effect among the studied extracts. Conclusion: In this study, chamomile extract inhibited the in vitro albumin glycosylation reaction. Clove and garlic extracts showed inhibitory effect in low concentration but this effect decreased with increasing of the extract concentration.

Background & Aim: Cinnamon is a plant with many pharmaceutical effects. The present research evaluated the effects of Cinnamon bark extract on serum proteins level in male Balb/c mice. Methods: In this experimental study, 40 small Balb/c mice were chosen and divided into 5 groups: a control group, a case group, and three treatment groups. Normal saline was administered as placebo to the case group while the control group received no injections.. Cinnamon extract in doses of 50, 100 and 200 mg/Kg/48hr were injected intraperitoneally for 20 days to treatment groups. The levels of pre albumin, albumin, alpha-1, alpha-2, beta and gamma globulins were separated electrophoretically and calculated from the pattern of electrophoretogram. Results: The result indicated that the levels of pre albumin decreased significantly in two experimental groups (doses of 50 and 100 mg/kg), the levels of alpha-1 and beta in 200 group, alpha-2 level in 100 and gamma in 100 and 200 groups increased significantly .The injection of 100 mg/Kg/48h extract of Cinnamon decreased (p<0.05) the albumin level in plasma in treatment group as compared to the control group. Conclusion: Results of this study indicated that the serum level of globulins has not changed dramatically by the extract of Cinnamon. Since albumin synthesis occurs in the liver cells‚ thus administration of Cinnamon may affect the function of liver cells.

Background & aim: The inflammation and necrosis in hepatocyte causes disorders in liver functions when induced with toxins. Medicinal plants have hepatoprotectivity effects and can inhibit the heptotoxicity progressing in the liver. In this study the hepatoprotectivity effect of Avicenniamarina hydro ethanolic leaves extract (AME) were investigated in malerats induced with carbone tetrachloride.

Methods: In this study, 42 male rats with 220-250 gr body weight were divided randomly in 6 groups (n=7): control, sham(taking olive oil, 2ml/kg/day, i.p),witness group(taking carbontetrachloride 1:1 with olive oil,2ml/kg, single dose, i.p) and treatedgroups: (1,2 and3inducedbycarbontetrachloride 1:1 with olive oil, 2ml/kg ,andafter2 hours 200, 400 and 800mg/kg  AME /dayfor4 days,i.p).Thecontrolgroup (taking normal saline, 0.5ml/day,i.p). Aftertheexaminationthebloodsampleswerecollectedfromheartdirectly and albumin, total protein, totalbilirobin and liver enzymes wereanalyzed.

Results: Carbon tetrachloride reduced serum albumin and total protein and increased total bilirubin in groups induced with ccl₄ significantly (P<0.001). In treated groups serum albumin and total protein increased and total bilirubin decreased compared with witness groups significantly (P <0.05). CCl₄ increased ALT, AST and ALP significantly and in treated group reduced significantly(P<0.001).

Conclusion: The Avicennia marina hydoethanolic extract has antioxidant and flavonoids compounds. These materials could be able to protect the tissues, such as liver tissue, from toxic agentssignificantly.
