OBJECTIVES To analyse the glycosaminoglycans of the adult human rotator cuff tendon matrix, to characterise changes in the glycosaminoglycan composition with age and in chronic rotator cuff tendinitis. METHODS Rotator cuff (supraspinatus) tendons (n = 84) and common biceps tendons (n = 26) were obtained from cadavers with no history of tendon pathology (age range 11-95 years). Biopsies of rot...

In order to elucidate a part of calmodulin actions in the hyperproliferative state in human epidermis, calmodulin activities in the psoriatic and in the normal human epidermis were determined using calmodulin-deficient phosphodiesterase from bovine heart and purified pig skin epidermal calmodulin as a standard. Skin samples were obtained from 11 normal healthy controls and from both the uninvol...

Alpha-1-C-hydroxymethylfagomine (7), 3-O-beta-D-glucopyranosyl-DMDP (12), and 2,5-dideoxy-2,5-imino-D-glucitol (13) were isolated from the Thai traditional crude drug "Non tai yak" (Stemona tuberosa), which also contains a high concentration level of alpha-homonojirimycin (0.1% dry weight). "Thopthaep" (Connarus ferrugineus) and "Cha em thai" (Albizia myriophylla) contained 1-deoxymannojirimyci...
