A stem cell is an undifferentiated cell that has special properties for two reasons (1) the ability to increase the number self-renewal and (2) the ability to be differentiated into many cell types, and can be classified into two types (1) embryonic stem cells and (2) adult stem cells. Recent reports found that the differentiated cells can be reprogrammed to embryonic stem-like cells known as induced pluripotent stem cells. In the field of veterinary medicine, much attention has been paid to mesenchymal stem cells (MSCs), one type of adult stem cells. Many reports reveal the success for treating animals; however, there are small number of research have been performed in Thailand. The advantages of using MSCs are it can be easily isolated and cultured, avoiding ethical problems, having little effect on host immune defense, low costs and can be further applied clinically. The limitations of using MSCs are purification, proliferation and differentiation capability. Therefore, a basic science of mesenchymal stem cells is very important for the research question and developments. Thailand should focus on clinical application for build the confidence and enhance the standard of veterinary medicine in Thailand in order to compare with veterinary profession from developed countries, especially innovative new treatment by using mesenchymal stem cells.

Three phase bone scintigraphy (TPBS) examined the viability of bone graft, revascularization, and bone formation using single photon emission computed tomography (SPECT) and the intravenous injection of 99M Technetium methylenediphosphonate (99MTc-MDP). Seven New Zealand White rabbits, aged 8 months had osteotomy of ulna performed, the left ulna substituted for natural biomaterial bone graft, containing gelatin sponge and hyaluronic acid, and the right ulna was replaced by vascularized autogenous bone graft. A post-operative scanning of bone using TPBS was done at 7 days and weekly, at week 1, 2, 4, 6, 8, 12 to evaluate revascularization and bone formation of natural biomaterial bone graft comparing with autogenous bone graft. The results demonstrated that the perfusion index and RCP of natural biomaterial bone graft and the autogenous bone graft in phases 1, 2, and 3 had no statistically significant difference when compared in between each week. The study also showed that, the ratio of the mean counts/pixel of the natural biomaterial bone graft in phase 3 had slightly lower than autogenous bone graft. This study provided model through which TPBS could evaluate revascularization and bone formation in this model. Natural biomaterial bone graft may be the same and as good a revascularization as autogenous bone graft although the bone formation of autogenous bone graft still has more efficiency than natural biomaterial bone.

ความหลากหลายทางชีวภาพของสัตว์ไม่มีกระดูกสันหลังหน้าดินและคุณภาพน้ำผิวดิน ภายในมหาวิทยาลัยมหิดล จังหวัดนครปฐม

A study on the biodiversity of benthic macroinvertebrates and surface water quality was carried out from February to April 2015 in five sampling sites located within Mahidol University, Nakhon Pathom Province. Water quality was assessed using physiochemical parameters in combination with macroinvertebrate composition and biodiversity indices. Correlations of biodiversity indices and physiochemical parameters were also determined. A total of 2,641 benthic macroinvertebrates from 16 families in 10 orders were collected and identified. The most abundant family was Corixidae in the order Hemiptera. Most of physiochemical parameters indicated that surface water in all study sites were still suitable for aquatic animals. The correlation analysis showed that temperature, dissolved oxygen (DO) and pH correlated with diversity index (P<0.01). Thus, benthic macroinvertebrates can be used as a biological indicator for the assessment of water quality.
