“…However, hydroxyapatite (HA) phase has been formed after immersion of bioactive glass powder in the SBF for 2 days (Fig. 1b) [14] confirmed by appearance of two characteristic HA peaks at 26°(002) and 32°(211). Other less obvious peaks could also be seen at 40°(310), 46.7°( 222), 50°(213) and 53°(004).…”

A 58S bioglass with a composition in the ternary system 58SiO 2 -33CaO-9P 2 O 5 (wt.%) was prepared by an innovation sol-gel process in which a small amount of ammonia was used to facilitate the condensation reactions within an acidic solution prepared by tetraethyl orthosilicate, triethyl phosphate and calcium nitrate tetrahydrate. The properties of synthetic glass were investigated by several techniques. The amorphous nature and high specific surface area (99.1 m 2 /g) of the obtained glass were confirmed by using X-ray diffraction and low-temperature nitrogen adsorption techniques, respectively. In vitro experiments were performed by soaking glass samples in the simulated body fluid (SBF). The XRD patterns and SEM images confirmed the bioactivity of the synthesized bioglass by formation of a dense and visible hydroxyapatite layer on its surface after 2 days of in vitro assays. The ICP-OES data illustrated the ion exchange behaviours between the bioglass 58S and the SBF solution.

Radiation therapy contributes to a significant increase in bone osteoporosis and skin loss. Various natural health products might be beneficial to reduce bone and skin alterations. Curcumin (CUR) medicines derived from natural plants have played an important role in health care. This study aims at synthesizing and evaluating the performance therapy of CUR-encapsulated bioglass-chitosan (CUR-BG-CH). In vitro, the antioxidant assay was evaluated by using 1,1-diphenyl-2-picrylhydrazyl free-radical (DPPH) scavenging and the nitroblue tetrazolium reduction. The CUR-BG-CH antimicrobial effects were tested in liquid media. In vivo, after rat (60) Co γ-radiation, the tissue wound-healing process was studied by grafting CUR and CUR-BG-CH in femoral condyle and dorsal skin rat tissue. The antioxidant studies indicated that CUR-BG-CH quenches free radicals more efficiently than unmodified CUR and had effective DPPH (91%) and superoxide anion (51%) radical scavenging activities. The CUR-BG-CH biomaterial exhibited an important antimicrobial activity against Staphylococcus aureus. The histomorphometric parameters showed amelioration in CUR-BG-CH-treated rats. An improved mechanical property was noticed (33.16 ± 5.0 HV) when compared with that of unmodified CUR group (23.15 ± 4.9 HV). A significant decrease in tumour necrosis factor-α cytokine production was noted in the CUR-BG-CH rats (90 pg/ml) as compared with that of unmodified CUR group (240 pg/ml). The total amount of hydroxyproline was significantly enhanced (33.5%) in CUR-BG-CH group as compared with that of control. Our findings suggested that CUR-BG-CH might have promising potential applications for wound healing.

The main objective of this research is the elaboration of bioactive glass 58S by an alkali‐mediated sol‐gel method. In which, the ammonia solution was used to transfer sol to gel state, and then the gel was dried by using the free‐drying technique. The dried gel was heated at 700°C in 2 h to convert into glass powder. The XRD analysis confirmed the amorphous and glassy properties of synthetic bioglass. The specific surface area of 99.146 m2/g of this bioglass was identified by using a low‐temperature nitrogen adsorption technique. In vitro experiments were performed by soaking the powder samples in the simulated body fluid (SBF) at several times. The XRD patterns and SEM images high lighted the bioactivity of bioglass by the formation of a dense and visible hydroxyapatite layer on the glass's surface after only 2 days of in vitro assays. ICP‐OES spectrometry was also used to illustrate the ion exchange behaviors between the bioactive glass 58S and the SBF solution.
