Abstract

Background and Objective: Curcumin is a combination of active polyphenol from the Curcuma Langa plant, which has extensive biological activities including effects anti-inflammatory, anti-bacterial and cytotoxic markers for multiple cancer cells. Berberine is an alkaloied isokinolin that is present in berberine and suppresses the growth of many tumor cells. This study was designed to determine the antibacterial effect of berberine and indium curcumin and indium diastile curcumin complexes against E-coli and Bacillus pumilus and comparison of their cytotoxicity on the cell lines of the bladder and stomach cancer cells.
Methods: In this descriptive-analytic study, antimicrobial activity and cytotoxicity effect of berberine and indium curcumin and indium diastile curcumin complexes was investigated by MTT and dilution test method respectively. E-coli [BL21 (DE 3)], Bacillus pumilus (PTCC 1529), cell lines of bladder (5637) and stomach (AGS) were evaluated.
Results: The minimum inhibitory concentration (MIC) of berberin for E-coli was determined 5 mM. At 100 micromolar concentration of berberine approximately 100% of the bladder cancer cells have disappeared. Cytotoxic effect of curcumin complexes on two bladder and stomach cancer cell lines showed that both complexes have different inhibitory effects on cell line life. Cytotoxicity of 20μM indium curcumin and indium diastile curcumin complexes for bladder cancer cells were 58% and 55%, respectively, and for stomach cancer cells were 61% and 34 %, respectively. Antibacterial activity of complexes against Bacillus pumilus and E-coli showed that none of the complexes has antimicrobial effect against Bacillus Pamilus, but both complexes inhibited the growth of E-coli bacteria. The bacteria population in the presence of indium curcumin and indium diastile curcumin complexes was reduced to 40% and 24%, respectively.
Conclusion: This study indicated that indium complexes of curcumin and diacetyl curcumin have a potential for anticancer and antibacterial therapy. Furthermore, berberine as an alkaloid has anticancer and antibacterial activity.

Abstract

Background and Objective: Methamphetamine is a highly addictive drug associated with severe psychosocial consequences and is extensively abused. This study aimed to determine the effects of four weeks of aerobic exercise and berberine supplementation on the expression of dopamine 5 receptor and poly (adenosin diphosphat [ADP]-ribose polymerase (PARP) genes in the heart tissue of methamphetamine-exposed rats.
Methods: In this experimental study, 30 female Wistar rats were randomly allocated into five groups of six: Control, methamphetamine, methamphetamine + aerobic exercise, methamphetamine + berberine, and methamphetamine + aerobic exercise + berberine. Intraperitoneal injections of methamphetamine (10 mg/kg) and aerobic exercise and berberine consumption (100 mg/kg) were administered for 4 weeks during the withdrawal period. The expression levels of dopamine 5 receptor and PARP genes was measured using real-time polymerase chain reaction (PCR).
Results: There was no significant difference in PARP gene expression between the methamphetamine group (1.02±0.65) and the control group (1.02±0.24). Similarly, there was no significant difference in dopamine 5 receptor gene expression between the methamphetamine group (5.74±4.94) and the control group (4.76±2.63). The expression levels of PARP and dopamine 5 receptor genes following exercise (1.01±0.55 and 4.30±1.96, respectively), berberine supplementation (0.61±0.25 and 2.97±1.45, respectively), and the combined intervention (0.67±0.30 and 3.43±1.87, respectively) showed no significant differences between the groups.
Conclusion: Short-term methamphetamine induction did not induce significant changes in the expression of dopamine 5 receptor and PARP genes in the hearts of methamphetamine-exposed rats.
