颈椎片判断青春快速生长发育研究进展

颈椎片能够象手腕骨片一样精确的判断骨龄，功能矫治中，根据X线定位头颅侧位片的颈椎影像判断生长发育情况，可以避免因拍摄手骨片而增加患者的放射量和经济负担。本文从不同的判断角度，就近年来的几种颈椎片分期方法进行综述，以期对临床有所帮助。

620例慢性胃炎胃镜黏膜象与舌苔关系的临床观察

中医历来重视舌苔在胃病辨证中的作用,认为舌苔乃胃气所生,病苔由胃气夹邪上蒸而成。《形色简摩·舌质舌苔辨》曰:“苔乃胃气之所薰蒸,五脏皆禀气于胃,故可借以诊五脏之寒热虚实也。”近年来,国内学者利用现代科学技术手段对舌苔的形成进行了广泛的研究,我院内窥镜室和中医科在     

关于青霉素超敏反应、皮内敏感试验等问题的探讨与实践三关于青霉素皮试期间应注意的问题

青霉素皮试前，采用何种消毒剂做皮肤消毒，对皮试结果判断的准确性有较大影响。如采用传统的消毒剂(75％酒精)，假阳性的出现几率明显增多．其产生原因可能系注药时消毒区酒精尚未完全挥发，残留者随穿刺动作渗入针孔，刺激局部皮肤所致．为避免假阳性结果的产生，改用mf—1消毒液，配制成1：80浓度应用，消毒效果良好又不影响皮试的准确性判别，值得推广。     

乳酸脱氢酶同工酶测定探讨

同工酶属于多种形式的酶类,虽然它们的蛋白结构不同,生理功用不同,以及理化性质不同,但它们的催化功能相同。为了建立较满意的乳酸脱氢酶(LDH)同工酶分离及测定方法,笔者采用本法对无心、肝、骨骼肌病症的正常人血清随机选择17例,采用琼脂糖电泳法对制板、点样、电泳、酶带染色、比色定量等实验条件进行了探讨。1实验原理以琼脂凝胶作载体,电泳分离血清,用试剂凝胶显色定位,以乳酶钾(或钠)为基质,在有氧化型酶工存在时LDH可使乳酸脱氢生成丙铜酸,使NAD(辅酶)还原为NADH2(还原型酶工),NADH2又将氢传递给吩嗪二甲酯硫酸盐(PMS),PMS…

上颌双侧磨牙形态异常1例

正常上颌第一、第二磨牙有独特的外形特征 ,尤其上颌第一磨牙 ,其牙冠外形和牙根数目都比较恒定。然而 ,笔者最近发现 1例 ,患者的上颌双侧第一磨牙、左侧第二磨牙牙冠及牙合面形态与常见的同名牙有明显差异 ,且牙根数目均为4个。笔者观察其牙冠牙合面形态与牙根数目可能有相关

广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.
