Core/shell capsules composed of calcium carbonate whisker core (rod-like shape) and chitosan/chitosansulfate shell were prepared by the layer-by-layer deposition technique. Two chitosan samples of different molecular weights (Mw=9.7×104and1.09×106g·mol-1) were used as original materials. Hollow capsules were also obtained by dissolution of the core in hydrochloric acid. Electron microscopy revealed that the surface of the shell is rather ragged associated with some agglomerates. The shell thicknesslobeys a linear relation with respect to the number of deposited layersmasl=md+a(a>0). The values ofd(thickness per layer) were 4.0 and 1.0 nm for the higher and lowerMwchitosan materials, respectively, both of which are greater than the thickness of the monolayer. The results suggest that the feature of the deposition does not obey an ideal homogeneous monolayer-by-monolayer deposition mechanism. Shell crosslinked capsules were also prepared via photodimerization reaction of cinnamoyl groups after a deposition of cinnamoyl chitosan to the calcium carbonate whisker core. The degree of crosslink was not enough to stabilize the shell structure, and hollow capsule was not obtained.

Herniated Discs

The literature has a lot of descriptions of the spontaneous disappearance of herniated discs. This article presents a clinical case of conservative treatment of sequestered disc herniation applying a complex of drug treatment and kinesitherapy. After 5 months a positive trend was observed against the background of conservative treatment. A year later, there was a lack of clinical symptoms and, according to MRI, and positive dynamics in the form of a decrease in the caudal sequestration of L5-S1 to symmetrical circular protrusion (hollow capsule effect). Key Words: sequestered disc herniation, drug treatment, kinesitherapy, MRI.
