Culture media supplemented with animal serum e.g. fetal bovine serum; FBS is commonly used for human culture expansion. However, for clinical application, FBS is restricted as its carry a risk of viral or prion transmission. Engineering autologous cartilage with autologous human serum supplementation is seen as a better solution to reduce the risk of transmitting infectious diseases and immune rejection during cartilage transplantation. The purpose of this study is to establish and compare the effects of 10% autologous human serum (AHS) and 10% FBS on the growth of chondrocytes and the formation of tissue engineered human articular cartilage.

Patient’s belief towards pain management may affect pain management outcomes and quality of life. The main aim of the present study was to determine the impact of a pre-operative pain education package towards pain belief among patients undergoing orthopaedic surgery in a tertiary hospital. A one-group pre-test post-test design study was conducted on orthopaedic surgery patients. Thirty respondents were recruited and pre-operative pain education was administered individually before surgery. Pre-operative and post-operative pain belief, management scores and side effects were measured using the Barrier Questionnaire (BQ-13). The results reported significant differences between pre-test scores (Mean = 41.87, Standard Deviation = 11.467) and post-test scores (Mean=34.80, Standard Deviation=13.026) of pain belief (t = 2.84, p = 0.004). There were also significant differences between pre-test scores (Mean = 37.10, Standard Deviation = 10.610) and post-test scores (Mean=30.80, Standard Deviation = 11.424) of pain management (t = 3.856, p = 0.0005). Respondent’s gender (t = -2.403, p = 0.023) and ethnicity (F = 5.038, p=0.014) reported significant differences with p value < 0.05, respectively. However, there were no significant differences between educational level, ethnicity, prior surgical history with pain belief (p> 0.05). There was positive impact of the pain education package towards pain belief and painmanagement among respondents who underwent orthopaedics surgery in a tertiary hospital. Reinforcement of pain educational program is pivotal in order to achieve optimal post-operative pain management.

The hepatoprotective activity of the ethanol extract of Astragalus kahiricus (Fabaceae) roots against ethanol-induced liver apoptosis was evaluated and it showed very promising hepatoprotective actions through different mechanisms. The extract counteracted the ethanol-induced liver enzymes leakage and glutathione depletion. In addition, it demonstrated anti-apoptotic effects against caspase-3 activation and DNA fragmentation that were confirmed by liver histopathological examination. Moreover, the phytochemical study of this extract led to the isolation of four cycloartane-type triterpenes identified as astrasieversianin II (1), astramembrannin II (2), astrasieversianin XIV (3), and cycloastragenol (4). The structures of these isolates were established by HRESI-MS and 1D and 2D NMR experiments. The antimicrobial, antimalarial, and cytotoxic activities of the isolates were further evaluated, but none of them showed any activity.
