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.
Brain tumour occurrence in Malaysia demonstrates an increasing trend from year to year among adults and the second most common cancer among children. Thus, the expansion of numerous research for novel therapy and treatment are necessary. The distribution of brain tumour in a specific population is important to provide substantial information about the current trends for developing new diagnostic technique and research. Consequently, this study is opted to provide descriptive data of brain tumour in Hospital Universiti Sains Malaysia (USM). 217 brain tumour cases were collected from the hospital record between 2011 and 2014. The brain tumour cases were confirmed by pathologists according to WHO classification and grading. Descriptive analysis was evaluated by using Microsoft Excel and IBM SPSS version 22. Gender preponderance in this study shows very little difference. The most common adult primary brain tumour in this study was meningioma (32.7%) followed by glioblastoma (7.8%), a type of diffuse astrocytic tumour. According to age factor, brain tumour distribution pattern shows an increasing trend as the age increases and meningioma is the most common among the elder patients. Secondary tumour takes more than 10% from overall percentage of brain tumour cases. In conclusion, the descriptive data presentation in this study is very helpful to provide baseline information on the current brain tumour occurrence in this region.
