Development of controlled release spheroids using natural polysaccharide as release modifier

A polysaccharide hydrogel was isolated from the seeds of Tamarindus indica (tamarind) and was used as release modifier for the preparation of diclofenac sodium spheroids, using extrusion-spheronization technique. The process was studied for the effect of variables to arrive at spheroids with satisfactory particle shape, size and size-distribution. The prepared spheroids were characterized for surface morphology, qualitative surface porosity, friability, bulk density, and flow properties. The in vitro release studies exhibited a zero-order release kinetics that was confirmed by Higuchi's and Peppas' models. A credible correlation was obtained among swelling index, viscosity, surface roughness of the polysaccharide, and in vitro dissolution profile of the spheroids. In the comparative bioavailability study, we found that the developed spheroids were able to sustain the drug release over 8 hr and could improve the extent of absorption and bioavailability of the drug.     

A Case Report of Prefilled Polysaccharide Hydrogel Breast Implant Rupture: Clinical,MRI, and Pathologic Findings

A case of a ruptured prefilled polysaccharide hydrogel breast implant with its radiologic and pathologic findings is presented. Usually, hydrogel spreads out in tissues with swelling and edema after rupture of an implant. However, in this case, a small amount of hydrogel leakage was misdiagnosed with ultrasonography as a benign breast mass. Therefore, it is advisable to evaluate a breast mass after augmentation with a hydrogel breast implant using magnetic resonance imaging to differentiate it from the hydrogel itself.     

Inhibitory effect of a polysaccharide from Tinospora cordifolia on experimental metastasis

Administration of the polysaccharide fraction from Tinospora cordifolia was found to be very effective in reducing the metastatic potential of B16F-10 melanoma cells. There was a 72% inhibition in the metastases formation in the lungs of syngeneic C57BL/6 mice, when the drug was administered simultaneously with tumour challenge. Biochemical parameters such as lung collagen hydroxyproline, hexosamines and uronic acids that are markers of neoplastic development were reduced significantly (P<0.001) in the treated animals compared with the untreated control animals. The treatment could also reduce serum γ-glutamyltranspeptidase (γ-GT) and sialic acid levels as compared to the control animals.     

青刺果多糖对糖尿病小鼠血糖、血脂含量的影响

目的研究青刺果多糖对四氧嘧啶诱导糖尿病小鼠的血糖、血脂等血液生化指标的影响。方法腹腔一次性注射四氧嘧啶复制模型。造模成功后,将实验动物分为模型组(生理盐水)、青刺果多糖治疗组(300 mg/kg)、阿卡波糖阳性药物治疗组(20 mg/kg)和正常对照组(生理盐水)。每组小鼠于给药后2周末、4周末分别测定空腹12h血糖、甘油三酯、低密度脂蛋白胆固醇、丙氨酸转氨酶、天冬氨酸转氨酶、尿素氮和总胆固醇的含量及小鼠体重。结果2周末,青刺果多糖治疗组和阳性药物治疗组与模型组相比,血糖、丙氨酸转氨酶均显著降低(P<0.05),甘油三酯、低密度脂蛋白胆固醇、天冬氨酸转氨酶、尿素氮和总胆固醇均无差异,体重明显升高(P<0.05);4周末,青刺果多糖治疗组和阳性药物对照组与模型组相比,血糖、甘油三酯、低密度脂蛋白胆固醇、天冬氨酸转氨酶、尿素氮均显著降低(P<0.05),丙氨酸转氨酶则极显著降低(P<0.01),对总胆固醇的影响无显著差异,体重逐渐增加接近正常。结论青刺果多糖具有降低糖尿病小鼠血糖水平,调节血脂紊乱和保护肝肾的功能。
