The only form of cellulose which could unequivocally be ascribed to the animal kingdom is the tunicin that occurs in the tests of the tunicates. Recently, high-resolution solid-state l3C NMR revealed that tunicin belongs to the Iβ form of cellulose as opposed to the Iα form found in Valonia and bacterial celluloses. The high perfection of the tunicin crystallites led us to study its crosssectional shape and to compare it with the shape of those in Valonia ventricosa (V.v.), the goal being to relate the cross-section of cellulose crystallites with the two allomorphs Iα and Iβ.In the present work the source of tunicin was the test of the ascidian Halocvnthia papillosa (H.p.). Diffraction contrast imaging in the bright field mode was applied on ultrathin sections of the V.v. cell wall and H.p. test with cellulose crystallites perpendicular to the plane of the sections. The electron microscope, a Philips 400T, was operated at 120 kV in a low intensity beam condition.

The unique position of man as a master mechanic of the animal kingdom is because of skilled movements of his hands and when this shoulder joints get obstructed, we call it as Apabahuka (Frozen shoulder), we do not find satisfactory management in modern medical science. Various effective treatment modalities have been mentioned which reverse the pathogenesis, Shodhana is advised initially followed by Shamana therapies. In the present study 30 patients were selected incidentally and placed randomly into two groups A and B, with 15 subjects in each group. Group A received Amapachana with Panchakola Churna, Jambeera Pinda Sweda and Nasya Karma. Group B received Amapachana with Panchakola Churna, Jambeera pinda Sweda and Nasaapana. In both the groups two months follow up was done. Both groups showed significant improvement in the signs and symptoms of Apabahuka as well as the activities of daily livings, thereby improving the quality of life of the patients. Nasya Karma and Nasaapana provided highly significant results in all the symptoms of Apabahuka. In the present study as per the clinical data, Nasaapana is found to be more effective than Nasya Karma.
