Enlightenment From Ancient Wisdom And Experience Of Urban Canal System Against Urban Waterlogging

This paper researches on the causes of the urban waterlogging after rainstorm, and studying on wisdom and experiences of urban canal system against urban waterlogging in ancient China. It is shown that urban canal system was of organic and multi-functions, being titaled as “the blood circulation of city” and that rivers were as the trunk drainage canals, with great density and section for flood passing, tremendous storage capacity, and perfect management. The Forbidden City and Ganzhou are two examples. Enlightenment from ancient wisdom and experiences will help us to solve urban waterlogging problems.

Static Quantity

A method is being developed which not only measures cerebral blood flow as a static quantity but also its changes with time. For that purpose a semiconductor device ascertains the proportion of intracerebral81 Rb and 81mKr activities. By opening the haemato-encephalic barrier in animal experiments a sufficient concentration of intracerebral81 Rb could be attained and the modified blood circulation after step-wise ligature of all brain arteries brought into relation to the corresponding Rb/Kr quotient. Over the range from undisturbed to completely interrupted cerebral blood flow this quotient varied up to 25% of its initial value.

Antithrombin Iii

SummaryInactivation of α- and β-thrombin by antithrombin-III and heparin was studied, since it had been suggested that two forms of thrombin exist with respect to heparin sensitivity (Machovich 1975b).It was found that the inactivation rates of α- and β-thrombin by antithrombin were different, namely α-thrombin was more sensitive to antithrombin than β-thrombin. Heparin facilitated the complex formation between α-thrombin and antithrombin-III, whereas β-thrombin inactivation was only slightly affected.Furthermore, heparin protected α-thrombin against the inactivating effect of heat, while β-thrombin lost its activity during the heat treatment.These findings suggest that the formation of β-thrombin in blood circulation may have an important role in thrombosis predisposition.
