刺血拔罐治疗第三腰椎横突综合征28例

笔者用刺血加拔罐的方法治疗第三腰椎横突综合征28例，取得较好疗效，现报道如下。     

STYLOID PROCESS SYNDROME LENGTFI AND PALPATION OF THE STYLOLD PROCESS

In 1980, 267 patients with related symp- toms were examined by tomography in our hos- pital. Among them the styloid process (SP) of 128 cases were 30 mm or more in length. Pha- ryngeal palpation was performed in 98. The SPs of 61 patients were palpable and tender. Diagno- sis was based on the related symptoms, tomogra- phy, positive pharyngeal palpation and SP tender- ness. Tomography showed that the longest SP was 75 mm, while the longest one with symptoms was 65 mm. The medial angulations of the SPs were from 100 t0 27° and the anterior angulations from 300 t0 50°.     

牛骨形成蛋白在骨不连中的临床应用

应用牛骨形成蛋白（ｂｏｖｉｎｅＢｏｎｅＭｏｒｐｈｏｇｅｎｅｔｉｃＰｒｏｔｅｉｎ简称ｂ－ＢＭＰ）成功的治愈１３例骨不连病人。经过１３个月～２９个月随访观察，效果较好。本组病人术前平均已做过１．５次手术。１３例病人中，有１２例被１次治愈。１例病人再次行内固定加用牛骨形成蛋白的植入也被治愈。骨形成蛋白的应用方式，采用同锻石膏复合后植入骨不连处。平均每个病人植入１００ｍｇＢＭＰ，１３例病人平均治愈时间为４．７个月。术后没有任何并发症。     

竹荪深层发酵菌丝体对小鼠免疫功能的影响及其抗肿瘤作用

过对食药用真菌──竹荪深层发酵菌丝体提取液对小鼠免疫功能及S－180肿瘤细胞的作用观察，表明其发酵菌丝体可明显提高小鼠腹腔巨噬细胞的吞噬功能（P＜0．01），并显著增加免疫器官的重量（P＜0．05）；对小鼠S－180肿瘤的抑瘤率为40．63％。     

抗淋球菌IgA蛋白酶单克隆抗体特性的初步研究

本文对以重组淋球菌ＩｇＡ蛋白酶为抗原制备的７株特异性ＭｃＡｂ的特性进行了初步研究。结果有５株（１Ｃ８、１Ｅ５、１Ｆ１１、１Ｇ３和２Ｅ６）能中和淋球菌ＩｇＡ蛋白酶活性。经相加试验初步证明，其中１Ｆ１１、２Ｇ３与其它３株ＭｃＡｂ的作用位点不同。因此，淋球菌ＩｇＡ蛋白酶至少存在３个中和表位。     

气管与主支气管肿瘤的影像诊断（附32例报告）

作者对３２例经病理证实的气管与主支气管良、恶性肿瘤的影像学表现进行分析，归纳为３型：腔内型、壁增厚型和腔内外型。后２种类型提示恶性，而无蒂的腔内型表现者不能鉴别良，恶性。作者还评价了常规体层、ＣＴ及ＭＲＩ诊断气管与主支气管肿瘤的优、缺点，讨论了影像诊断的作用。     

Effects of 5-Hydroxytraptamine on Aggregation,Release Reaction and Mobilization of Cytosolic Free Calcium Concentration in Rabbit Normal and Washed Single Platelets

In rabbit platelet rich plasma (PRP), 5-hydroxytraptamine (5-HT,0.03～3μmol/L) induced decrease in light transmission (DLT) dose-de pendently with centralization, as revealed by electron microscopy. However, 5-HT did not induced platelet aggregation and release reaction. 5-HT-induced DLT was inhibited by methysergide (0.3～30μmol/L), indomethacin (0.3～10μmol/L) and PGE_1 (0.01～0.3μmol/L) in a dose-dependent manner, but not EGTA(0.3～3mmol/L). Collagen(Coll), arachidonic acid (AA), adenosine diphosphate (ADP) and a stable thromboxane A2 analoge(STA_2) also induced DLT before aggregation by themselves, which was also inhibited by PGE_1, but not inhibited by EGTA except for Coll However,Coll-, AA-, STA_2-and ADP-induced DLT were reduced by pretreatment of PRP with 5-HT dose-depen-dently. The duration of DLT by Coll and AA were decreased from 151.4±5.93 sec and 15(?)38±0.60sec to 45.44±4.04 sec and 9.00±1.25 sec respectively ((?)±s(?) P<0.01), but not by ADP and STA_2, 3μmol/L of ADP-and 0.3μmol/L of STA_2-induced aggregation which was not accompanied with release reaction were enhanced by 5-HT pretreatment, but in those (Coil 5μg/ml, AA 100～200μmol/L and STA_2 1～3 μmol/L) with release reaction, the amount of adenosine triphosphate(ATP)were suppressed significantly (P<0.001) by 5-HT pretreatment without the effect on the magnitude of aggregation, The mobilization of cytosolic free calcium concentration ([Ca~(2+)]i) was observed after 5-HT treatment in single washed platelet, the results indicated that the basic level of [Ca~(2+)] i was 64.78±3.24nmol/L and this level was increased dose-dependently and significantly at 30 sec after administration of 5-HT and the time of peak value of [Ca~(2+)] i was at 90～100 sec.The similar time courses of suppression of ATP released during aggregation, in cases of Coll(5μg/ml), AA (200μmol/L) and STA_2(3μmol/L), by 5-HT were also found in the present experiment.
