Zamzam is holy water believed by Muslim to have remedial power for all kinds of diseases. It contains
many electrolytes and the concentration of the electrolytes may be affected by the types of container
used for its storage. This study was carried out to determine the difference in ions concentration of
Zamzam water stored in plastic and glass containers, and to determine cytotoxicity effects of Zamzam
water against U-87 cell line (human primary glioblastoma cell line). Ion Chromatography (IC) was used
to analyze the concentration. The analyzed anions in the Zamzam water include bromide, chloride,
phosphate, nitrite, nitrate, sulfate and fluoride whereas the cations were ammonium, lithium, potassium,
sodium, calcium and magnesium. Subsequently, MTT assay was used to determine the cytotoxicity of
Zamzam water on U-87 cell line. This study reveals that Zamzam water anions and cations
concentration was not statistically significant neither in plastic nor glass container. In addition, the
Zamzam water did not cause any toxicity on the U87 cell line. We postulate that types of container do
not have much influence on the ion concentration of Zamzam water and it is non-toxic on U87 cell line.
Zamzam water is blessed water originated from Mecca and is believed by Muslims to have the ability to cure illness. This ability to cure illness is due to the fact that zamzam water has higher concentration of minerals especially sodium, calcium and magnesium which play a vital role. Sodium is reported to be involved in the regulation of the Mu-Opioid Receptor, which indirectly leads to the production of cAMP. Hence, this current study was carried out to investigate the synergistic effects of zamzam water and methadone combination on cAMP levels in human primary glioblastoma cell line (U-87 MG) after chronic morphine administration. Materials and Methods:The time course and concentration of morphine on U-87 MG cell line was determined. The U-87 MG cell line was incubated with morphine (25 μL/mL) for 24h, to make the cell dependent on morphine and later treated with different combinations of 3.2 mL of zamzam water and methadone (5, 10, 25 μL/mL). The levels of cAMP was determined using the enzyme-linked immunosorbent assay kit. Results:The result revealed that 3.2 mL of zamzam water incubated with 10 μl/mL of methadone significantly prevented the overshoot production of cAMP level (p
