高强度超声对犬前列腺组织损伤的实验研究

目的　探讨经尿道高强度超声 (transurethralhighintensityultrasound ,TUHIU)治疗良性前列腺增生症 (benignprostatichyperplasia ,BPH)的有效性和可行性。方法　对犬前列腺进行TUHIU辐照处理 ,辐照后不同时期处死动物以观察其急性、亚急性和慢性期大体及组织病理变化。同时观察辐照前后影像学变化。结果　TUHIU辐照前前列腺部尿道平均最大宽度为 0 66± 0 12 ( x±s)cm ,辐照 3周后前列腺部尿道平均最大宽度为 2 11± 1 0 7cm ,较辐照前显著增宽。辐照后可见靶区内尿道周围腺体发生凝固性坏死 ,3 0～ 60天后坏死组织脱落尿道呈囊腔状。光、电镜下均可见腺上皮及基质细胞发生均匀性凝固性坏死。辐照后经腹B超示前列腺内部出现液性暗区 ,前列腺呈囊性改变。辐照后即刻各犬均出现短暂性尿潴留、尿频、尿线变细 ,1月后恢复正常。结论　TUHIU可破坏前列腺组织 ,明显增加前列腺部尿道宽度。     

Breast Volume Measurement in Young Chinese Women and Clinical Applications

The authors carried out research on breast volume and body surface anatomy of 125 women. As a result, an average breast volume for Chinese women was obtained (325.36 ± 12.66 ml), and a table with several linear equations for calculating breast volume was derived. The authors applied these results to their clinical work and succeeded in making mammaplasty more precise in 178 patients.     

Protection of chickens against highly lethal H5N1 and H7N1 avian influenza viruses with a recombinant fowlpox virus co-expressing H5 haemagglutinin and N1 neuraminidase genes

Inactivated whole avian influenza virus (AIV) vaccine provides protection against homologous haemagglutinin (HA) subtype virus, but poor protection against a heterologous HA virus. Moreover, it induces chickens to produce antibodies to cross-reactive antigens, especially nucleoprotein, which is limits AIV serological surveillance. In this study, a recombinant fowlpox virus co-expressing HA (H5 subtype) and NA (N1 subtype) genes of AIV was evaluated for its ability to protect chickens against intramuscular challenge with a lethal dose of highly pathogenic (HP) AIV. Susceptible chickens were also vaccinated by wing-web puncture with the parent fowlpox vaccine virus. Following challenge 4 weeks later with HPAIV, all chickens vaccinated with recombinant virus were protected, while the chickens vaccinated with either the unaltered parent fowlpox vaccine virus or unvaccinated controls experienced 100% mortality following challenge. This protection was accompanied by the high levels of specific antibody to the respective components of the recombinant vaccine. The above results showed that rFPV-HA-NA could be a potential vaccine to replace current inactivated vaccines for preventing AI.     

125~I－后标记检测DNA－蛋白质交联物的研究

１２５~Ｉ－后标记法是庄志雄等人（１９９４）提出的一种检测ＤＮＡ－蛋白质交联物（ＤＰＣｓ）的新技术，该法在检测离体ＣＨＯ细胞ＤＰＣｓ的实验中已显示出敏感、快速和简便的优点。本研究表明，１２５~Ｉ－后标记法不仅能有效地检出由紫外光和铬酸钾诱导的ＣＨＬ细胞ＤＰＣｓ，并能有效而敏感地检测由铬酸钾和氯化镍引起的大鼠不同组织特别是白细胞ＤＰＣｓ形成的情况，是一种敏感的和可考虑应用于人群调查的ＤＰＣｓ检测方法。     

白癜风患者血小板的研究

测定７５例白癜风患者周围血象、血小板相关抗体（ＰＡＩｇＧ）、血小板粘附及聚集、第３因子功能、高岭土部分凝血活酶时间（ＫＰＴＴ）、一期凝血酶原时间（ＰＴ）。结果发现白癜风患者血小板减少，ＰＡＩｇＧ增高、聚集时间延长。提示这种异常与免疫有关。     

CURATIVE EFFECT OF LICORICE ACID ZINC ON CHILDREN WITH LOW SERUM ZINC

Zinc is closely related to children's health and growth.' We selected 120 children with low serum zinc. Adopting random double-blind method, we treated two groups of children,. 60 each, with sulphate zinc syrup and licorice acid zinc capsules respectively.     

Electrodermal and microcirculatory activity in patients with fibromyalgia during baseline, acoustic stimulation and cold pressor tests.

The peripheral sympathetic activity was studied in 27 patients with fibromyalgia and 29 healthy controls through simultaneous measurements of electrodermal variables and blood flow at palmar skin sites during baseline, acoustic stimulation, and cold pressor tests. Compared to the controls, the patient group showed a significantly larger overall increase in the skin electrical conductance and less vasoconstriction during acoustic stimulation and cold pressor tests. These findings imply an increased activity of cholinergic and decreased activity of adrenergic components of the peripheral sympathetic nervous system in patients with fibromyalgia.
