A 3-month-old male domestic shorthair cat was presented for evaluation of stranguria and hematuria and a 4-year-old male domestic shorthair cat was presented for evaluation of stranguria. For cat 1, a swollen prepuce, erythematous preputial orifice, and urine pooling from the preputial orifice were noted. The preputial orifice was a pinpoint opening and penis was not extruded from the prepuce. For cat 2, a necrotic skin around the preputial orifice, small preputial orifice, and severe urine pooling from the preputial orifice were noted. The round-shaped resection of the tip of the prepuce was performed to increase the diameter of the preputial orifice and remove erythematous fragile skin or a necrotic skin around the preputial orifice and the edematous, redundant preputial mucosa in these 2 cats. The preputial mucosa was then apposed to the ipsilateral incised skin edge. There was no recurrence of clinical signs over 22- and 24-month follow-up period, respectively. The round-shaped resection technique provided adequate enlargement of the preputial orifice to allow extrusion of penis in these 2 cats with a phimosis. This technique could be helpful in cases with skin and mucosa necrosis around the preputial orifice that require round-shaped resection.

Purpose : To evaluate the cause of asymptomatic bacteriuria (AB) or aseptic pyuria (AP) on physiologic phimosis and to evaluate the effect of topical steroid therapy and preputial hygiene on the resolution of AB and AP. Methods : Ninety uncircumcised boys (age 1-72 month, median 16 month) with AB or AP were examined for physiologic phimosis and allocated by the preputial retractibility into the non-retractile group (n=59) or the retractile group (n=31). Topical steroid therapy [topical application of hydrocortisone (0.1%) cream with physiotherapy] were prescribed (three times a day) and the method of preputial hygiene (gentle retraction of prepuce and water cleansing) was instructed to the non-retractile group. After 2-4 weeks, the preputial retractibility was reevaluated and urine examination was repeated. To the retractile group, only the method of preputial hygiene was instructed and urine examination was repeated two weeks later. Results : Among 90 boys with AB and AP, 65.6% (59/90) had the nonretractile prepuces and nonperformed preputial hygiene. In the nonretractile group, the prepuces became retractile in 81.4% (48/59) after topical steroid therapy. Among boys (n=48) whose prepuces became retractile after topical steroid therapy, AB or AP resolved in 77.1%, decreased in 18.7% and persisted in 4.2%, which were significantly different to 18.2%, 2.37%, 54.5% in boys (n=11) whose prepuces were persistently nonretractile (P=0.0114). In the retractile group (n=31), 65.2% was compliant to preputial hygiene. In boys (n=23) who were compliant to preputial hygiene, AB or AP resolved in 65.2%, decreased in 26.0% and persisted in 8.2%, which were significantly different to 12.5%, 50%, 37.5% in boys (n=8) who were not compliant (P=0.0457). Conclusion : Physiologic phimosis was an important cause of AB or AP. Simple topical steroid therapy on the nonretractile prepuces and good preputial hygiene could improve AB or AP.

An 10-day-old, male Jindo puppy was presented with anuria. This puppy was diagnosed as agenesis of prepuce and preputial orifice. To treat anuria exploratory operation was performed and the penis was found in situ under the skin. The penis was protruded outside of the skin. Because of strangulation and dryness of the penis by growing up, the artificial prepuce was made by making the subcutaneous tunnel. After that this puppy showed normal urination and had no complication. In case of the agenesis of the prepuce with the penis in situ, artificial prepuce by subcutaneous tunnel would be an alternative choice for saving the puppy.

Mononitrotoluenes were reduced to aminotoluenes using porphyrin as a catalyst in the presence of several types of reductants including hydrogen sulfide and 1, 4-dithiothreitol(DTT). Intermediates and final products of porphyrin-catalyzed reduction of mononitrotoluenes were identified and a pathway for the reduction of the nitro group to the corresponding amino group was proposed. The optimum pH for the reduction was determined. The catalytic activity of the porphyrin was confirmed by UV/VIS absorption spectra and basic kinetics of porphyrin-catalyzed reduction were studied. Of several types of reductants tested, DTT sodium hydrosulfite, and hydrogen sulfide were seen to give significant reduction of nitrobodies. When hydrogen sulfide was used as a reductant hydrogen sulfide and nitrotoluenes were removed simultaneously.

Product yields were determined for the reaction of styrene with sodium hypochlorite (NaOCl) in CH$_2$Cl$_2$ with various substituted manganese porphyrin complexes as catalysts. In the presence of the electron withdrawing group and ortho-substituted manganese porphyrin complexes, reaction rate and epoxide selectivity are increased. Also reaction rate and epoxide selectivity are largely increased by the presence of imidazole which behaves as axial ligand of the manganese porphyrin complexes. By the kinetic study with Michealis-Menten equation, the factor significantly affected to catalytic ability is $K_m$ value. A large binding affinity consists with the low $K_m$. With theoretical analysis by EHMO calculation, the results are in good agreement with experimental data.

Polymer bonded metalloporphyrins are synthesized by reaction between Fe(III) protoporphyrin or Mn(II) tetrakis(4-N-carboxyphenyl)porphyrin with polystyrene divinylbenzene copolymer. The spectroscopic properties of synthetic polymer bonded metalloporphyrins are investigated by using resonance Raman spectrometer. By synthetic polymer bonded metalloporphyrins as catalyst, which are model of cytochrome P-450 and peroxidases, epoxidation of olefins and oxidation of alkanes are achieved with H2O2 as oxidant. The catalytic efficiencies with polymer bonded metalloporphyrins are improved on that with corresponding nonpolymer bonded metalloporphyrins. Especially those can be reused because of stability against oxidant. Electron donating imidazole derivatives, which are attached in 5th position of central metal of metalloporphyrins, enhance the catalytic efficiencies.

웅묘의 요도폐색의 외과적 치료법으로는 1971년 이후 Wilson의 회음요도루 조성술이 널리 사용되고 있다. Wilson법에선 요도와 피부를 직접봉합하나, 신축성이 없는 피부가 골반강방향으로 잡아 당겨져서 요도개구부가 좁아지기 쉽고 또 환축이 수술부위를 자주 핥으므로 봉합한 곳이 풀려지기도 하고 또 오줌에 의한 피부염이 일어나기 쉬운 결점 등이 있다. 그러나 이번 실험한 술기은 피부로부터 포피점막, 요도점막으로 이행시키기 때문에 피부가 요도구쪽으로 늘어나 이것이 작아질 염려가 전혀 없고. 오줌에 의한 피부염도 잘 일어나지 않는 이점이 있었다. 이것은 포피점막에는 신축성이 있고 그것이 양적으로 여유가 있기 때문에 더욱 요도가 수술후 골반강방향으로 매몰되기 때문에 봉합부를 환축이 혀로 핥을 수 없는 점은 대단히 이롭다.
