溴酸盐的遗传毒性

目的 探讨臭氧消毒饮用水副产物溴酸盐的遗传毒性。方法 采用Ames试验、UDS试验和微核试验，从基因水平、DNA水平和染色体水平对臭氧消毒副产物溴酸盐的遗传毒性进行研究。结果与阴性对照组相比，副产物溴酸盐不能使组氨酸缺陷型鼠伤寒沙门菌回复突变增加，但可使大鼠肝细胞程序外DNA合成增加和小鼠骨髓嗜多染红细胞微核形成率增加。结论 臭氧消毒副产物溴酸盐可能具有DNA及染色体水平的遗传毒性。

Die Durchblutung handgenähter und geklammerter Colonanastomosen

Zusammenfassung In einer tierexperimentellen Studie wurde die Durchblutung nach Anlage einer handgenähten und geklammerten End-zu-End-Anastomose am Schweinedickdarm verglichen. Bei keinem der 15 Tiere trat ein Nahtleck auf. Im Bereich handgeknoteter Fäden konnten einzelne umschriebene minderdurchblutete Gebiete festgestellt werden, die am 7. und 14. postoperativen Tag deutlich sichtbar wurden, wenn die Anastomosen vermehrt vascularisiert waren. Bei den Klammernähten wurden solche Ausfälle der Gewebsdurchblutung nicht gesehen. Die intramuralen Arterien zogen unbehindert durch die B-förmig gestalteten Klammern hindurch. Ein unauffälliges Gefäßmuster und eine abgeschlossene Anastomosenheilung wurden bei den Klammernähten nach 3 Wochen und bei Handnähten nach 4 Wochen beobachtet.

Blood supply of stapled and sutured colonic anastomoses

Summary The blood supply of end-to-end staple and suture lines in the pig colon was compared. In 15 operated animals there was no anastomotic leak. Sporadic circumscribed areas of restricted circulation could be noticed in hand-sewn anastomoses. This effect was marked on the 7th and 14th postoperative day, when vascularisation of the anastomoses was increased. Such lack of vascular supply was not seen in stapled anastomoses. The intramural arteries passed through the B-shaped staples without hindrance. An unremarkable vascular pattern and a completed healing of the anastomoses were observed after 3 weeks in staple lines and after 4 weeks in suture lines.

Topographical analysis of the EEG effects of a subconvulsive dose of lidocaine in healthy volunteers

Background: The purpose of the present study was to assess the effects of intravenous lidocaine on spatial changes of electroen-cephalographic power and on psychomotoric status in conscious volunteers.
Methods: In 11 healthy volunteers lidocaine (2-min bolus, 100 mg; 15-min infusion, 40 μg kg^-1 min^-1) or placebo were given intravenously in a randomized, single-blinded, two-way crossover study. Haemodynamics and lidocaine plasma concentrations were measured at baseline and within a period of 30 min following bolus injection. Vigilance and emotional status were tested using visual analogue scales (VAS). Toxic CNS effects were evaluated by a questionnaire. The raw EEG (17 leads, reference C_z) and computed power spectra were continuously recorded.
Results: The chosen lidocaine dosage led to nearly constant plasma concentrations (unbound lidocaine 2.5 min and 15 min after bolus 0.36±0.14 μg/ml and 0.30±0.06 μg/ml, respectively [mean±SD]). The placebo caused no symptoms, changes in VAS-scores or EEG-parameters. Lidocaine induced pronounced subjective symptoms and significant increases in delta activity for 15 min, most dominant at the frontotemporal and occipital leads (max. +219% O₁). Frontal and occipital beta1 and beta2 power (max. +131% and +124% at O₁, respectively) was immediately increased after the bolus injection. No EEG changes occurred at central region C_z, and no interhemispheric EEG differences were noted. Theta, alphal, and alpha2 power remained unchanged.
Conclusion: The current data demonstrate simultaneous changes in psychomotoric status as well as delta and beta spectral power during lidocaine infusion. These data could be an indication that the pronounced frontotemporal and occipital EEG changes are the electroencephalographic expression of subjective sensations.     

Diagnosis and therapy for primary hepatic carcinoma: Transcatheter inferior phrenic arteriography and chemoembolization

Summary Transcatheter inferior phrenic arterial (IPA) and hepatic arteriography was performed on 38 patients with advanced primary hepatic carcinoma (PHC) with blood supplied by IPA and hepatic artery. 18 patients received single treatment with hepatic arterial infusion (HAI) or embolization (HAE) 20 received double treatment with IPA and hepatic arterial infusion or embolization. The results show that the double treatment is superior to the single one. The angiographic features and mechanism of parasitization of inferior phrenic arterial supply to PHC were also discussed.
