The kidney, heart and lung were examined of cats fallen sick lower urinary tract disease(LUTD). There cases typically clinical findings were urinary retention, hematuria, dehydration, cytoplegia and uremia. It is believed that these histopathological and clinical findings resulted from the struvite crystal thrombus in ureter. But we have many factors of an unsolved problem on LUTD. Accordingly, this LUTD demands to process of pathological diposition.

A total of 18 lower urinary tract disease(LUTD) cats were examined by radiographical finding. It is difficult of descend to particular on struvite crystal intraurinary bladder by the usual radiographical technique. However, we have lots of informations by imaging processing method on standing-up position radiograph. This method be helpful from now on LUTD research work.

A study was carried on histopathology of LUTD. Based on this study, it was noted that a plural number of factors and some genetic mechanisms are participating in onset of this disease, which should have to be studied further in future in omnidirections.

Some vanadium(III) complexes have been prepared by the reaction of VCl3${\cdot}$3MeCN with ligands and characterized by elemental analysis, 1H-NMR, infrared and UV-Visible spectroscopy. 3,5-lutidine(lutd), 8-hydroxyquinoline(oxine), 1,2-phenylenediamine(phda), ethylenediamine(en), and sym-diphenylethylenediamine(dpen) were chosen as coordinating ligands. ${\nu}$(V-Cl) of lutidine complex occurs at 418 $cm^{-1}$ and the other complexes (oxine, phda, en, dpen) occur at 337∼347 $cm^{-1}$. The value of ${\nu}$(V-Cl) indicates that the former complex has trigonal bipyramid structure and the latter complexes have octahedral structure. The ${\nu}$(C${\equiv}$N) of acetonitrile in oxine and phda complexes are characteristically shifted to about 70 $cm^{-1}$ higher frequency compared with that of free ligand (2260 $cm^{-1}$). The ${\delta}$(C${\equiv}$N) is also shifted to about 60 $cm^{-1}$ higher frequency compared with that of free ligand (377 $cm^{-1}$). Finally each vanadium(III) complex showed the following formulation; [$VCl_3(lutd)_2$], [$VCl(oxine)_2$MeCN]$Cl_2$, [$VCl(phda)_2$MeCN]$Cl_2$, [$VCl_2(en)_2$]Cl, [$VCl_2(dpen)_2$]Cl.
