Thiamine deficiency in utero alters response to ethanol in adulthood

To determine whether prenatal thiamine deficiency, a frequent concomitant of alcoholism, reduces the response to ethanol during adulthood in the rat as does ethanol exposure in utero (Abel et al. 1981), pregnant Sprague-Dawley rats received either control or thiamine deficient diets together with daily injections of the thiamine antagonist pyrithiamine. At 7 months of age, male offspring were exposed to precisely regulated ethanol vapor concentrations in an inhalation chamber for 24 h and blood ethanol concentrations (BECs) and ethanol-induced intoxication were determined. Prenatally thiamine deficient rats and controls were indistinguishable in terms of appearance, body and liver weights, and the ratios of liver to body weight and brain to liver weight. However, total body water was significantly greater, and BECs and behavioral impairment were decreased, in the experimental rats. These findings indicate that prenatal thiamine deprivation is associated with reduced pharmacologic effect of ethanol as a result of increases in its volume of distribution and rate of metabolism.     

Correction of webbed-neck deformity in Turner's syndrome

Summary A case of Turner's syndrome with the typical marked webbing of the neck is presented. A posterior approach is preferred for correction of this webbed neck deformity. A butterfly shaped portion of excess skin is excised and the margins of the defect mobilised as four flaps. The flaps are sutured with a very short midline vertical component, resulting in an almost X-shaped scar. The first procedure resulted in only a partial correction of the deformity and an excess of hypertrophic scar tissue. This was treated with a repeat of the procedure but the midline wounds was repaired with mulitple small Z-plasties. The final appearance of the neck was satisfactory in the lateral profile, but there was still some excess tissue posteriorly.     

“津血同源”“肾为唾”的研究

以23例肾功能不全与20例肾功正常患者的唾液尿素氮、钠、钾、舌面pH值和血液的相应生化检查作对照。结果唾液尿素氮、钾与血尿素氮、钾成正相关性。证实了中医“津血同源”“肾为唾”的理论。

Cerebrovascular deaths before and after the appearance of oral contraceptives

The mortality of cerebrovascular diseases in Denmark was analysed for men and women 15-44 years of age, in a 14-year period before and after the appearance of oral contraceptives (OC) in 1966. 1,670 deaths were registered over 28 years, during which the female incidence of cerebrovascular deaths increased by 19% (P less than 0.025), while the male mortality was unchanged. Women showed a percentage increase in deaths from cerebral thromboembolic attacks (CTA) of 33%, men a fall of 14%. The increase of female CTA deaths was most pronounced in the young fertile group, the age group with a high OC use. A relative risk of CTA of 3.3-4.5 for OC users compared with non-users could explain the CTA trend difference between women and men. No other single risk factor responsible for the observed trends could be identified. Both women and men had a significant increase in the mortality of subarachnoidal hemorrhages, and a significant fall in the mortality of intracerebral hemorrhages.     

特发性身材矮小儿童成骨细胞的功能状况

目的通过检测特发性身材矮小(ISS)儿童血清骨碱性磷酸酶(BAP)及骨钙蛋白(OC)水平,探讨其成骨细胞的功能状况。方法ISS组36例及健康对照组儿童50例。ISS组分为青春期前组及青春期组。测各组儿童身高、体质量、体质量指数,采用CHN法评定左侧手、腕部骨化指标,计算骨龄。采用ELISA法测其血清BAP及OC水平。结果青春期前,ISS儿童血清BAP及OC水平为(79.90±25.96)U/Lvs(60.96±18.46)μg/L,健康对照组为(152.17±35.36)U/Lvs(76.16±28.03)μg/L;青春期,ISS儿童血清BAP及OC水平为(108.33±35.20)U/Lvs(63.82±24.81)μg/L,健康对照组为(156.30±35.29)U/Lvs(104.92±28.26)μg/L。青春期前及青春期ISS组血清BAP及OC水平均明显低于健康对照组,存在显著性差异(Pa<0.01)。结论ISS儿童以成骨细胞为中心环节的骨塑造和再造能力均较健康生长发育少年儿童差。     

Effect of 5-Aminoisoquinolinone on the Adhesion of Colon Carcinoma

Objective： 5-Aminoisoquinolinone, a water-soluble, potent inhibitor of the activity of poly （adenosine 5＇-diphosphate ribose） polymerase, plays an important role in the tissue injury associated with ischaemia-reperfusion injury and inflammation by inhibiting the activity of poly （adenosine 5＇-diphosphate ribose） polymerase and the expression of cell adhesion molecules such as ICAM-1, P-selectin et al. But how about it in the tumor is not clear. The aim of the present study was to study the effects of 5-Aminoisoquinolinon on the adhesion of colon carcinoma line HT-29 cells to human umbilical vein endothelial cells; and the effects of 5-Aminoisoquinolinon on the expression of ICAM-1, P-selectin and the activity of poly （adenosine 5＇-diphosphate ribose） polymerase in colon carcinoma HT-29 cells. Methods： The adhesion of HT-29 cells to human umbilical vein endothelial cells was detected by adhesive experiment. Immunocytochemically Streptavidin-Peroxidase method was used to investigate the expression of ICAM-1, P-selectin and Poly （adenosine 5＇-diphosphate ribose）（ the product of poly （adenosine 5＇-diphosphate ribose） polymerase activation）. Results： the results of the adhesion assay of HT-29 cells to HUVEC showed that the OD570 value in each 5-AIQ-treated group was significant lower than that in the control group （5-AIQ-untreated） in a dose-dependent manner. The expression of ICAM-1, P-selectin and Poly （adenosine 5＇-diphosphate ribose） was significant lower in 5-Aminoisoquinolinone-treated HT-29 cell group than that in 5-Aminoisoquinolinoneuntreated groups. Conclusion： The data suggest that 5-Aminoisoquinolinone can inhibit the adhesion of HT-29 cells to human umbilical vein endothelial cells. 5-Aminoisoquinolinone also can inhibit poly （adenosine 5＇-diphosphate ribose） polymerase activation and the expressions of ICAM-1 and P-selectin in HT-29 cells. 5-Aminoisoquinolinone probably contributes to the prevention of tumor cell metastasis. Further study is needed.

人胎儿前庭器超微结构的观察

对人胎儿前庭器超微结构的研究,国内外报道甚少。本文对18至36周人胎儿颞骨10具进行了扫描电镜和透射电镜的观察,并对应用Surface preparation法制做人胎儿前庭器标本的方法进行了探讨。本文观察所见:豚鼠平衡斑的生理状态与人胎儿很近似,体面积比人胎儿平衡斑小,感觉毛长,细胞排列更整齐。28周以后的胎儿因前庭周围骨质变硬,制做标本时可以分别取出两囊斑和壶腹嵴。
