Analysis of six cases concerning clinical features of rhinolith / 临床耳鼻咽喉头颈外科杂志

To analyze six cases concerning clinical features, the treatment process and curative effect of Rhinolith. The six patients had unilateral nasal obstruction, three of them were accompanied with purulent nasal discharge, two had blood with them, one patient had repeated hemorrhage of nasal cavity and two patients had developed headache. By using endoscopic, four irregular stones which are yellow, gray and brown were found in the middle and back end. Because of the severe nasal septum deviation and inferior turbinate polypoid, the stone could not be seen clearly but could be touched by aspirator. In sinus CT examination of 6 cases, it showed incomplete irregular shapes and had high density unilateral nasal cavity in the posterior segment. 4 patients had nasal deviation, 3 patients had ipsilateral sinusitis. 4 patients removed their stone by using endoscopy, 2 patients took the stone away after correction of nasal septum. Pathologic diagnosis: rhinolith. Two patients also had exogenous foreign matters which were considered as pseudo nasal stones.

Comparison of the relative content of trichosanthin between root and callus derived from Trichosanthes kirilowii / 中国药学杂志

OBJECTIVE：The relative content of trichosanthin (TCS) of the calli induced from the leaves of Trichosanthes kirilowii Maxim. was measured and a comparison between the calli and the root was made. METHODS：TCS was obtained by the fractional precipitate with acetone from the homogenate of the root or the calli. To examine and measure TCS, several methods, such as immuno-precipitation reaction, SDS-PAGE and electrophoregram scanning, were usde. RESULTS：The results of immuno-precipitation reaction and SDS-PAGE showde that TCS existed in the calli and in the root of T.kirilowii Maxim.. It was found that TCS was the richest component in the acetone precipitated crude extract of the calli with a relative content of 44.22% TCS in the extract, though the absolute content of TCS in the calli was less than that in the root. CONCLUSION:Extracting TCS from the calli derived from leaves has not been reported previously. The absolute content of TCS in the root is 2.66 times more than that in the calli.
