Ritodrine hydrochloride was remarkably effective for pain of uterus metastases from thymic carcinoma, a case report

A forties year-old female visited our hospital on March 2011, complaining chest discomfort. Computed tomography (CT) revealed a huge mass in the anterior mediastinum combined with multiple masses in the lungs, the uterus and the bone. Since no abnormal shadow had been noticed on the chest radiograph on January 2011,they seemed to have grown very rapidly in a short period. The pathological diagnosis following needle biopsies of mediastinal and uterine cervix tumors was undifferentiated carcinoma of the thymus metastasizing to the uterus. She was also suffering from the pain on the right femur and intermittent hypogastralgia due to metastases to the bone and uterus. Although NSAIDs and oxicodone relieved the pain on the right femur, they could not significantly reduce the hypogastralgia. Judging from the nature of the frightful hypogastralgia, the cause was estimated to be not somatalgia but splanchnodynia. Ritodorine hydrochloride, which was then adnimistered for the purpose of inhibiting the contraction of the uterine, was remarkably effective in reducing the pain. According to the literatures reviewed concerning metastases of the extrapelvic malignant tumors to the uterus, the median survival period after occurrence of metastases was 14 months. This report suggests that the administration of Ritodorine hydrochloride can keep the quality-of-life of these patients without suffering from the pain due to metastatic tumor to the uterus.

Experimental researches of antidysmenorrhea actions of Compound Yimucao Paste / 中成药

AIM: To investigate the antidysmsenorrhea pharmacologic effects of Compound Yimucao Paste (Herba Leonuri, Rhizoma chuanxiong, Radix Angelicae Sinensis, Flos Carthami) METHODS: The methods of microcirculation and isolated uterus smooth muscle of rat were used. RESULTS: Compound Yimucao Paste could improve the microcirculation disturbance on the aspects of the diameter, the velocity of mice auricle microarterioles and microveins, inhibit the isolated uterus smooth muscle contraction and mouse twister induced by oxytocin. CONCLUSION:Compound Yimucao Paste has an obvious action of blood quickening and stasis transforming and inhibit the isolate and uterus smooth muscle contraction induced by oxytocin, which are contributed to its antidysmenorrhea effect.
