A case of intussusception of a ureter due to a ureteral polyp was observed. Ureteral intussusception have been exceedingly rare, and very few reference to this condition can be found in the medical literature. The author have report a 39 years old female of a case of intussusception of the ureter associated with a benign polyp. The author have performed satisfactory conservative treatment. The patient was entirely recovery and has remained in excellent health since.

There is considerable experimental evidence to indicate that tumor growth is dependent on angiogenesis. However, we do not understand how the angiogenic activity is initiated by a given tumor. There is a clear distinction between a stage without neovascularization, which correlates with a paucity of metastases, and a stage in which increasing neovascularization correlates with a rising rate of metastasis. The authors therefore asked whether the extent of angiogenesis in human prostatic carcinoma is correlated with the tumor grades or some growth factors. To investigate how tumor angiogenesis correlates with tumor aggressiveness, the authors counted microvessels within the various grades of invasive prostatic carcinomas of 44 patients and the nodular hyperplasias of 10 patients. Highlighting of the vessels by immunohistochemical staining for factor VIII-related antigen and assessment of the tumor aggressiveness by the degree of expression of some growth factors(transforming growth factor-alpha, and beta, epidermal growth factor), tumor necrosis factor-alpha and tumor grading(Gleason's score) were done. As a result, both microvessel counts and the expression of growth factors and tumor necrosis factor correlated with tumor grades. In conclusion, the number of microvessels per 200 X fields in the areas of most intense neovascularization in a prostatic carcinoma may be a predictor of the patient's prognosis. Therefore, assessment of tumor angiogenesis may prove valuable in selecting patients with prostatic carcinoma, especially small needle biopsy, for aggressive therapy.

The one event on signaling mechanism is the cleavage by adenyl cyclase of ATP into second messenger, cyclic AMP. The other transfer system of inositol metabolism, it is widely recognized that hydrolysis of the minor membrane lipid phosphoinositide bisphosphate (PIP₂) initiated by occupation of certain receptors and catalyzed by phospholipase C, lead to toe generation of the two intracellular messengers, inositol triphosphate (IP₃) and diacylglycerol (DG). IP₃ is converted to inositol tetrakisphosphate (IP₄) by IP₃ kinase. In the present study, it is that purification of calmodulin is used by phenyl-Sepharose CL-4B chromatography, it's molecular weigh, 17,000 in SDS-polyacrylamide gel electrophoresis. In order to observe the affinity between calmodulin (CaM)-Affigel 15 and IP₃ kinase, and isolated IP₃ kinase, was applied in CaM-Affigel with Ca²⁺ equilibrium buffer and EGTA equilibrium buffer. We compared with binding and elution effect of IP₃ kinase in several condition of buffer. In affinity of binding, Ca²⁺ equilibrium buffer was in the most proper condition, and elution, CaM/Ca²⁺buffer (CE 1 10.36, CE2 12.76pM/min/mg of protein) was effected much more than EGTA buffer (E2 1.48, E 2.43pM/min/mg of protein), but CaM/Ca²⁺stimulate the activity of IP₃ kinase. And then, several detergents such as sodium deoxycholate, tween 20, cholic acid, polyethylene glycol, chaps were applied. The 0.2% chaps buffer (E2 23.19, E3 8.05pnM/min/mg of protein) was the most effective in elution of IP3 kinase.
