As cinchonine is not produced in our country and the ignition of mercurous tungstate is a troublesome operation leads us to examine critically the determination of tungsten as barium tungstate.The results of our experiments reveal that barium tungstate should be precipitated from a boiling solution of pH 7.2—8.0 with a rather large excess of barium chloride. The concentration of the precipitant, after precipitation, should be maintained within eight tenth to two millimolar, in order to obtain acceptable results....

As cinchonine is not produced in our country and the ignition of mercurous tungstate is a troublesome operation leads us to examine critically the determination of tungsten as barium tungstate.The results of our experiments reveal that barium tungstate should be precipitated from a boiling solution of pH 7.2—8.0 with a rather large excess of barium chloride. The concentration of the precipitant, after precipitation, should be maintained within eight tenth to two millimolar, in order to obtain acceptable results. The barium tungstate precipitates may be ignited at 500—900°. When they are dried at 105 or 150°, they weigh several tenth milligrams heavier than that after ignition, presumably due to very small amounts of occluded water. The carbonate (from carbon dioxide in air and in water used) and chloride (from the precipitant) contents of the precipitates are negligible, being less than three and three to four parts per thousand respectively, while no precautions are taken to remove or guard against carbon dioxide con tamination. This method of determination may be used to estimate as low as six milligrams of tungsten trioxide. The exclusion of carbon dioxide during the determination, as suggested by Buscarons Ubeda et al and Duval et al, is found to be unnecessary. The influence of several ammonium, potassium and sodium salts are studied. Among them, sodium and ammonium acetates interfere the least, and potassium chloride the most. For detail please refer to Fig. 3 in this paper.

本文敍述用鎢酸鋇法测定鎢的適宜條件。沉澱應在pH7.2—8.0,微沸的溶液,用熱氯化钡溶液進行。沉澱劑應在沉澱後仍維持0.8—2毫克分子濃度。過低則沉澱不完全,過高則結果偏高。灼燒沉澱温度為500—900°。本法可以测定6毫克及以上的三氧化鎢。沉澱中的碳酸鹽(<3‰)和氯化物(當沉澱劑過量为50—100%時,3—4‰)均可不顧。隔絕或除去二氧化碳也無必要。幾種銨、鉀和鈉鹽的影響亦曾加以探討。

The clinical, operative and pathological characteristics of 59 consecutive cases of intracranial epithelial (epidermoid) tumors are reported. These cases constituted 1.1% of all intracranial tutrors and 13.5% of congenital neoplasms admitted to our neurologic service in the period of 1951-1981. Among them, 37 were males, 22 were females with a sex ratio of 1.8:1. Their ages ranged from 7 to 59 years (average 33.4 yrs) with duration of disease up to the time of admission varied from 1 month to 15 years (average...

The clinical, operative and pathological characteristics of 59 consecutive cases of intracranial epithelial (epidermoid) tumors are reported. These cases constituted 1.1% of all intracranial tutrors and 13.5% of congenital neoplasms admitted to our neurologic service in the period of 1951-1981. Among them, 37 were males, 22 were females with a sex ratio of 1.8:1. Their ages ranged from 7 to 59 years (average 33.4 yrs) with duration of disease up to the time of admission varied from 1 month to 15 years (average 3.5 yrs). Of 53 (89.8%) subdural tumors, 43 (72.9%) located in the subarachnoid spaces or cisterns, especially more often in the cerebellopotine angle cisterns(20 cases). The tumors were soli din 39 cases(66.1%), cystic in 13 cases(22%), and the remaining 7 cases not stated.There were no specific clinical features on which one could base for identifying the nature and extent of the tumor. Headache, vomiting and papilledema were among the more common symptoms. Analysis with detailed discussion were made on the diagnosis and treatment including evaluation of CT as a diagnostic means. Total removal of the tumor were performed in 17 cases(29.8%), subtotal or large portion removal in 34 (58.6%), partial removal in 4(6.9%), only a shunting procedure in 1 case(1.7%)and 2 cases not stated(3.4%). The overall surgical mortality rate was 8.6% (5 cases). The incidence of postoperative aseptic meningitis was 28.3%. Follow-up for a period of 0.5 to 20 years (average 8.5yrs)in 36 patients (67.9%) . Among 20 patients with subtotal or large portion removal, 1 died of recurrence, 3 died of other diseases, the remaining 16 had returned to their normal activity without recurrent manifestations. The results of this study suggest that the primary treatment of epithelial tumors should be surgical removal including the content and capsule of a cystic type. This, however, must be carried out on the guard against causing additional neurological interference. Patient with incomplete removal can also obtain a long-term favorable result.

报告59例颅内上皮样肿瘤(表皮样肿瘤)的临床、手术和病理特点。在59例中,6例(10.2%)在硬脑膜外,其余53例(89.8%)的肿瘤位于硬脑膜下,其中43例(72.9%)位于蛛网膜下腔或脑池,尤多见于桥脑小脑角池(20例)。39例(66.1%)肿瘤为实质性,13例(22%)为囊性,7例记载不详。由于本病在临床上缺少特征性的表现,故难以据此作出诊断。高颅压表现仅见于38.6%病人。CT是较好的一种诊断方法。通过手术和随访资料的分析表明,为取得较好的治疗效果,在手术时应在不增加神经损伤的基础上,尽量切除瘤内容及其包膜(囊壁)。
