Students in tertiary level education are mostly young adults that are transiting from the teenage years to adulthood. Since there is less restriction as compared to their teenage years, university and college students might involve in risky behaviours that may affect their health, social and academic performance. Thus, the purpose of this study is to investigate and identify the differences of health risk factors and health promoting behaviour that have been practiced by students in Malaysia. A cross sectional study was conducted using closed-ended questionnaires distributed to university and college students via emails. The results showed that 77.0% students claimed they have no health problem. However 49.0% of the non-medical students did not know whether they have normal BMI. Among the medical students, 62.0% rarely do physical exercise even though most are seriously concern about their fat consumption (95.0%). Only 30.0% of the total students have awareness of wearing seat belt. For health promoting behaviour, 33.0% of female students have never perform breast self examination (BSE), while 65.0% of male students have never perform testicular self examination (TSE). These findings confirmed that there are differences in health risk factors and health promoting behaviour that have been practiced by the students.
This study is to qualitatively evaluate a locally produced hydroxyapatite (HA), made by AMREC-SIRIM in an experimental animal bone defect using New Zealand White (NZW) rabbits. HA cylindrical blocks measuring 2.5 mm (D) x 1.0 mm (H) were implanted in the rabbits' left tibia. The tibias were harvested within one to three weeks post-implantation. The implantion site was cut into thin undecalcified sections of about 30 microm to 60 microm and stained with Toluidine Blue and Goldner's Masson Trichrome. Microscopic examinations using standard light microscopy of these slides were performed.
Hydroxyapatite is a calcium phosphate bioceramic that has been shown by many authors to be biocompatible with bioactive properties. It is widely accepted as the best synthetic material available for surgical use as a bone graft substitute. HA granules produced by AMREC-SIRIM from local materials underwent 5 types of sterilisation techniques with different ageing periods. Samples were tested for chemical and phase composition and microbial contamination before and after being sterilised. From the microbiological tests done, none of the unsterilised positive control yielded a positive culture. Results from X-Ray diffraction studies found that all the sterilisation techniques did not chemically degrade or structurally change the HA granules significantly.
