中西医结合整复较长时间的小儿肠套叠

肠套叠是小儿常见的急腹症，空气灌肠是诊断治疗肠套叠最简便、最有效的方法，但肠套叠时间较长的病例往往不能奏效。这部分病例通过手术观察有70％左右未见肠坏死，仍有整复可能。因此，我们对48小时以上的患儿根据临床症状，选用中西医结合的方法进行整复，收到了满意的效果。     

冰点下降法测定血、尿渗透压的临床应用及注意事项

本文应用溶液冰点下降法测定了178例正常血清渗透压。结果为287±13毫渗量/kg水。并对20例尿崩症病人在限水加压素试验过程中测定血清,尿渗透压。尿崩症病人尿渗透压明显低于正常人。注射加压素后,尿渗透压升到正常。在多尿症的鉴别诊断中,此法是一种简便,灵敏的手段。有重要的诊断价值。     

巨趾症一例报告

患儿女性,4岁,因左(足母)趾先天性巨大入院。出生时左(足母)趾即较对侧明显粗大,且随年龄增粗增长。以后行走自如,但影响穿鞋。患儿系足月平产,第一胎,智力发育中等。其母孕期无患病用药史及有害物质、射线接触史。父母非近亲婚配,家族中亦无先天性遗传疾病患者。查:生长发育正常。其他脏器未发现畸形。双足不对称,左足背内侧及(足母)趾明显丰满粗大,(足母)趾长6cm,周经9cm,局部皮肤色泽正常,甲呈竭色,干燥、无光泽、不平整,(足母)趾关节活动正常。右(足母)趾发育正常,长3.5cm,周径5.6cm。X线摄片示左侧第一跖骨及(足母)趾第一、二节趾骨均较对侧长且粗。经左(足母)趾末节截除并局部修整术后,双(足母)趾大小、形态近似,能着鞋,行走无障

双酚胺酸对小鼠和大鼠氯化镍解毒及分布的影响

AIM: To study the effect of catecholamic acid (CBMIDA) on detoxication of NiCl2. METHODS: Mice and rats were injected s.c. or i.m. CBMIDA immediately after i.p. NiCl2. Each mouse was injected i.p. CBMIDA after i.v. 63NiCl2 185 kBq, and radioactivities of various tissues were measured with liquid scintillation counter at 24 h. The localization of 63Ni was shown by the whole-body autoradiography. RESULTS: CBMIDA s.c. 0.5-1.5 g.kg-1 markedly reduced the mortality from acute poisoning of i.p. NiCl2 500 mg.kg-1. After i.p. NiCl2 in mice, the LD50 was 82.7 mg.kg-1. Mice were injected s.c. CBMIDA 1.5 or 2.5 g.kg-1 after Ni poisoning, the LD50 of NiCl2 were raised to 789 or 820 mg.kg-1, respectively. The LD50 of NiCl2 was 39 mg.kg-1 in rat. If CBMIDA was injected i.m. 0.5 g.kg-1 after i.p. NiCl2, the LD50 was 332 mg.kg-1. CBMIDA 1.5 g.kg-1 i.m. after i.v. 63NiCl2, decreased the contents of 63Ni in blood and lung of mice vs control mice at 24 h. The contents of 63Ni in brain, heart, spleen, and kidney were similar to those of the control mice. The content of 63Ni in bone was more than the control. The excretions of 63Ni through urine and feces were not increased by CBMIDA at 24 h. The whole-body autoradiography showed that the radioactivity was highly localized in the kidney, lung, and Harder's gland. There was a moderate level of 63Ni in the liver, bone, skin, and blood. A pronounced accumulation occurred in the bone. There was a marked reduction of 63Ni in the lung, skin, liver, and blood after i.p. CBMIDA. CONCLUSION: The CBMIDA markedly raised the survival rate of nickel-poisoned mice and rats, and decreased 63Ni levels in lung and blood.
