Portal pressure measurements at different sites were performed in 22 patients with liver cirrhosis and in 28 control patients by a modified equipment, “Lumbal manometer”. The hemodynamic changes of portal pressure in portal hypertension and the relationship between these changes and varices formation and bleeding, especially the important role of the elevation of CVP (coronary vein pressure) are discussed. Moreover, the rationality and effectiveness of PCDV are also dealt with in this article. From the above we are led to conclude that PCDV (pericardial devascularization) is a rational procedure and is recommendable for patients with liver cirrhosis and varices hemorrhage, especially for poor risk patients.

The carotid pressor reflex can be blocked by rhomotoxin. The intensity of the blocking effect depends upon the original level of blood pressure and is in correlation with the dosage of rhomotoxin given intravenously. Thus the antihypertensive effect may be ascribed to some extent to the blockade of carotid pressor reflex caused by rhomotoxin and is irrelevant to the changes of blood volume, since this depression of reflex is more prominent than that at the same blood pressure level induced by bloodletting.

In diesem Artikel wird über 10 Arten von Saugwürmern innerhalb von 5 Familien, 8 Gattungen, berichtet, die in 93 Tieren im. Waldgebiet Shennongjia, Provinz Hubei, China, gefunden wurden, nämlich Platynotrema hubeiense sp. nov., Lyperosomum armenicum, Brachylecithum attenuatum, Pagumogonimus veocularis, Pagumogonimus skrjabini syn. Paragonimus szechuanensis, Fasciola hepatica, Fasciola gigantica, Clonorchis sinensis, Eurytrema coelomaticum und Ogmocotyle sikae.

Die erste Art ist noch nicht beschrieben, sie wurde von uns “Platynotrema hubeiense sp. nov.” benannt. Ihre morphologischen Charakteristika sind: Bauchsaugnapf größer als Mundsaugnapf, Ösophagus verhältnismäßig lang, Ovarium dicht am hinteren Rand des Bauchsaugnapfs, Eidotterdrüse gut entwickelt, erstreckt sich über die beiden mittleren Viertel der Körperlänge, Eier relativ klein. Exemplare dieser Würmer sind im Institut für Parasitologie der Wuhan-Medizinischen Hochschule zu sehen.

5 Spezies (Pagumogonimus skrjabini syn. Paragonimus szechuanensis, Fasciola hepatica, Fasciola gigantica, Clonorchis sinensis, Eurytrema coelomaticum) können den Menschen infizieren; für diese 5 Arten ist Shennongjia ein natürlicher Infektionsherd. Deshalb sind, um während der Entwicklung der Forstwirtschaft Zoonosen zu verhüten, parasitologische Untersuchungen in den Waldgebieten von großer praktischer Bedeutung.

The experimental results showed that the fecal coliform (FC) to fecal streptococcus (FS) ratio (FC/FS) in the human feces and in warm-blooded animal feces were rather different. FC/FS ratio in the human feces was greater than 7.0, and in warm-blooded animal feces was less than 1.0. Therefore, under certain conditions, the FC/FS ratio of polluted water may be used as an index to distinguish human fecal pollution from animal fecal pollution.
