Causes and Differentialdiagnosis of Hematospermia

The authors examined the most frequent causes of hematospermia on their clinical material. They describe - in the order of importance - the examinations needed to discover pathological diagnostics. They call the attention to the importance of differentiation of "clear" hematospermia and hemato-pyospermia and review the possible ways of therapy.
Ursachen und Differentialdiagnose der Haematospermie

Zusammenfassung

Anhand eigener Beobachtungen wird zur Problematik der Haematospermie Stellung genommen. Dieses Symptom gelangt nicht so häufig zur Beobachtung, allerdings stellt die Haematospermie ein Symptom dar, das sehr ernst genommen werden muß. Die Autoren unterscheiden zwischen einer „klaren” Haematospermie und einer Pyo-Haematospermie, wenn es sich zusätzlich um eine eitrige Entzündung handelt. Die für die Differentialdiagnose wichtigen einschlägigen Untersuchungsmethoden werden beschrieben. Die wesentlichen Grundsätze der Therapie werden erläutert.     

去甲乌药碱对实验性心力衰竭的治疗作用

去甲乌药碱(DMC)是中药附子的有效成分之一。静脉滴注DMC2μg/kg/min共5min,使豚鼠正常心脏的收缩力明显加强,LVSP和LV dP/dt_max分别增加58±7和25±7%;心衰后,LVSP和LV dP/dt_max分别下降到心衰前的40±5和30.5±2.8%。DMC可使之恢复到79±14和75±9.9%,DMC也能加强离体豚鼠衰竭心脏的收缩力。DMC的强心作用与ISO相似,但前者作用较弱,作用维持时间较长,这可能与他们的作用机制不同有关。     

环丙沙星在预防酒精对肝细胞再生抑制中的作用

急性或慢性酒精中毒可不同程度抑制肝细胞ＤＮＡ合成和肝细胞再生。多数学者认为酒精抑制肝细胞再生与酒精抑制聚胺 (Ｐｏｌｙａｍｉｎｅ ,包括四甲烯二胺、精脒和精胍 )合成有关[1,2 ] 。实验证明 ,γ 氨基丁酸 (γ ａｍｉｎｏｂｕｔｙｒｉｃａｃｉｄ ,ＧＡＢＡ)是聚胺代谢的衍生物 ,是神经传递介质之一 ,是细胞增生调节中的抑制剂。Ｍｉｎｕｋ等[3 ] 指出 ,酒精中毒的实验动物血液中ＧＡＢＡ浓度升高 ,ＧＡＢＡ可能激活了肝脏ＧＡＢＡ受体 ,改变了细胞内环境。因此 ,酒精抑制肝脏合成聚胺可能是由于ＧＡＢＡ介导的结果。Ｄｉｅｈｌ[2 ] 认…     

Liver transplant outcomes in a Canadian First Nations population

BACKGROUND:

A higher incidence of autoimmune disorders may predispose First Nations (FN) individuals to higher rates and more severe episodes of rejection, graft loss and mortality following liver transplantation for advanced liver disease.

METHODS:

A retrospective review of patient outcomes in a single centre providing long-term follow-up care for FN and non-FN patients transplanted for advanced liver disease was conducted.

RESULTS:

A total of 20 FN and 129 non-FN charts were available for review. FN subjects were younger at transplantation (mean [± SD] age 32.4±4.1 years versus 46.3±1.4 years; P=0.00005), less often male (35% versus 58%; P=0.05), more commonly transplanted for autoimmune hepatitis (30% versus 4.7%; P=0.006), less often from urban residences (25% versus 74%; P=0.0001) and less compliant with medical care (20% versus 80%; P=0.007). After a mean follow-up period of 11.0±1.5 years and 8.4±0.5 years in FN and non-FN subjects, respectively, the incidence and severity of rejection, graft and patient survival were similar between cohorts.

CONCLUSION:

Although demographic profiles, nature of the underlying disease and compliance differed, the rates and severity of rejection, graft and patient survival were similar in FN and non-FN patients who underwent liver transplantation for advanced liver disease.     

争光霉素A6和它在争光霉素复合物的地位

争光霉素A₅已鉴别为Bleomycin A₆,在争光霉素复合物中所占比例一般在10%左右,在某些批样中可高达15%以上。文献报告Bleomycin A₆在天然产的Bleomyein复合物中只有痕量。通过向发酵培养基中加入特定组分的末端胺可大大提高其特定组分在复合物中的含量比而其它组分的产生则不同程度地被抑制。但Bleomyein A₆例外,即使向培养基中加入其末端胺精胺(0.3mg/ml),在所产生的复合物中大大增多的组分是Bleomyein A₆,而Bleomycin A₆仍只有痕量。这表明争光霉素产生菌有和Bleomycin产生菌明显不同的特点。

Anatomical variations of the internal iliac veins in the presacral area: Clinical implications during sacral colpopepxy or extended pelvic lymphadenectomy

The purpose of this study was to classify anatomical variations of the internal iliac vein (IIV) in relation to robotic or laparoscopic extended lymphadenectomy. Between March 2011 and July 2012, 60 consecutive patients underwent robotic or laparoscopic extended lymphadenectomy. We retrospectively reviewed surgical video clips and analyzed the pattern of the IIVs in the presacral area. IIV variations were classified into seven types: Type A, normal (n = 39, 65.0%); Type A with a dilated middle sacral vein (n = 5, 8.3%); Type B, left IIV connecting centrally to the left external iliac vein (n = 5, 8.3%); Type C, a separated trunk of the left IIV draining into the left central common iliac vein (CIV; n = 1, 1.7%); Type D, a separated trunk of the right IIV draining into the left central CIV (n = 8, 13.3%); Type E, a separated trunk of the right IIV draining into the right central CIV (n = 0, 0%); and Type F, separated trunks of the bilateral IIV connecting with each other before draining into the left central CIV (n = 2, 3.3%). The prevalence of IIV anomalies was 26.7%; the incidence of separated IIV trunks was 18.3%. To prevent life‐threatening IIV injury during extended lymphadenectomy or sacral colpopexy, the anatomical variations of the IIVs should be known exactly. Clin.

Human immunodeficiency virus infection in patients with leukemia

Eighteen human immunodeficiency virus (HIV)-seropositive patients were found among 211 previously treated adult patients with a variety of leukemias who had been multiply transfused before April 1985. Patients known to be homosexual or intravenous drug users were excluded from this study. The spouse of one HIV-seropositive patient became HIV infected and subsequently developed the acquired immune deficiency syndrome. Patients with leukemia who were multiply transfused before the availability of screening of blood products for HIV antibody should be counseled regarding their individual risks of HIV infection and the risk to sexual contacts.
