Studies of the reproductive toxicity of Rumalaya

The reproductive toxicity of the complex plant preparation Rumalaya was studied in experiments on white mongrel rats. Rumalaya at doses of 400 and 2000 mg/kg given via the intragastric route with simultaneous application of cream to the skin was found to have no embryotoxic or teratogenic actions and had no significant effect on the postnatal development of offspring or the generative functions of female or male rats. Thus, these data identified no contraindications to the clinical use of this agent in pregnant women. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 41, No. 8, pp. 3–6, August, 2007.     

Biomechanics of lumbosacral spinal fusion in combined compression-torsion loads

The current study investigates the stabilizing effects of three different types of spinal fusion to the juxta-free motion segments and to the fused segment of the lumbosacral spine under combined compression-torsion loads. Sixteen fresh human cadaver lumbosacral spines were tested under a simulated physiologic loading condition. The relative movements of the motion segments, as well as the angular rotations and the center of rotation were then computed and analyzed. The average torsional stiffness of the unfused three-motion segment was found to be 2.35 nm/degree. After fusion, the torsional stiffness did not increase significantly. Under the compression-torsional load, the anterior and bilateral-lateral fusions provided adequate stabilizing effect on the fused segment. The posterior fusion provided the least amount of stabilizing effect. These findings are similar to the results of the compression-bending experiment. Whereas the compression-bending loads produced significantly increased stress at the juxta-free segments, the compression-torsional loads did not produce any significant amount of increase in torsional stress at the juxta-free segments.

Controlled release of antiseptic drug from poly(3-hydroxybutyrate)-based membranes. combination of diffusion and kinetic mechanisms

A polymeric system based on biocompatible and biodegradable poly(3-hydroxybutyrate) (PHB) is proposed for controlled release of furacilin (Frc). The kinetics of Frc release from PHB membranes containing 0.5–5.0 wt% Frc into a model aqueous medium at 25°C have been studied using a UV spectroscopy technique. The drug release profiles present a combination of diffusion and kinetic components. The diffusion component of the release kinetics has been analyzed and the dependence of the diffusivity on the drug concentrations has been determined. The rate constant of the release kinetics depends on the Frc concentration and is related to the hydrolytic destruction of PHB. The PHB hydrolysis is most clearly demonstrated in long-term experiments (after the first week of drug release). The obtained results are useful for the development of new controlled drug delivery systems containing several drugs, which provide a combined action on tissues and organs of the organism. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 41, No. 12, pp. 30–33, December, 2007.
