An interspinous process distraction device includes a curved plate which is formed with an upper plate and an opposite lower plate by bending a board material, with the upper plate being penetrated with two upper wire holes and the lower plate being penetrated with two lower wire holes; an upper fixing wire, two ends of which penetrate from bottom to top the two upper wire holes of the upper plate to be tied on a spinous process; and a lower fixing wire, two ends of which penetrate from top to bottom the two lower wire holes of the lower plate to be tied on the spinous process. This interspinous process distraction device is provided with a low manufacturing cost and high durability.
摘要:
A liquid crystal composition containing an optically active or a ferroelectric liquid crystal compound represented by the following formula: ##STR1## wherein: A is selected from the group consisting of oxygen and sulfur; B is selected from the group consisting of --(CH.sub.2).sub.m -- and --(CH.sub.2).sub.n --O--; R is an alkyl or alkoxyl group having 1 to 22 carbons; R' is an alkyl group having 2 to 8 carbons or an ether group having 2 to 8 carbons; m is an integer from 0 to 4; n is an integer from 2 to 5; k is an integer of 0 or 1; l is an integer of 0 or 1; C and D are selected form the group consisting of hydrogen atom and halogen atoms, and * represents a chiral center. The ferroelectric liquid crystals of the present invention exhibit optical and chemical stabilities, high-speed switching characteristic and high spontaneous polarization, and thus are excellent materials for use in liquid crystal devices and liquid crystal light switching elements.
摘要:
A skin wound dressing is disclosed. The skin wound dressing comprises Tremella polysaccharide and alginate and is used to cover on a skin wound to accelerate wound healing. The Tremella polysaccharide is isolated from a hot water extract of Tremella fuciformis. The skin wound dressing is a Tremella polysaccharide composite fiber, a Tremella polysaccharide sponge or a Tremella polysaccharide hydrogel.

摘要:
It has been found that the polysaccharide isolated from a hot water extract of a Tremella mushroom without adding a chemical reagent has a novel effect of preventing and/or treating of intestinal disorder. The Tremella polysaccharide has excellent stability, water absorbing and holding ability, and swelling capacity, so it can be used to raise fecal water content and increase fecal volume, so as to improve intestinal disorder characterized by constipation and symptom caused by constipation.
摘要:
It has been found that the polysaccharide isolated from a hot water extract of a Tremella mushroom without adding a chemical reagent has a novel effect of inhibiting melanin formation effects, so it can be used to lighten the spots on the skin when being applied to the skin. In addition, the Tremella polysaccharide of the present invention has excellent moisturizing effect.
