Isolation of a novel GPI-anchored gene specifically regulated by p53; correlation between its expression and anti-cancer drug sensitivity.

We have identified a novel gene inducible by wild-type p53. A significant correlation between expression of this gene and p53 status in cells derived from esophageal cancers indicated that this gene is likely to be specifically regulated in a p53-dependent manner. As the predicted amino acid sequence showed a high degree of homology to the family of glycosyl-phosphatidylinositol (GPI)-anchored membrane proteins, we termed this gene GML (GPI-anchored molecule-like protein). Introduction of GML cDNA suppressed the growth of esophageal cancer cells in culture. A correlation between the presence of GML expression and the sensitivity of esophageal cancer cells to anti-cancer drugs implied that the gene product plays a significant role in the apoptotic pathway or cell-cycle regulation induced by p53 after DNA damage.

Characterization of the human p57KIP2 gene: alternative splicing, insertion/deletion polymorphisms in VNTR sequences in the coding region, and mutational analysis.

We have isolated human cDNA and genomic clones of a gene termed p57KIP2, which is related to the p2I WAFI and p27 KIP1 genes that encode inducible inhibitors of cyclin-dependent kinase activity. The p57 gene contains three GC-rich introns of 166 bp, 566 bp, and 83 bp, and two of the four exons correspond to coding regions. Alternative splicing generates the heterogeneity in the translational initiations. As this gene has been localized to chromosomal band 11pI5.5, a region thought to be the location of a tumor suppressor gene(s) for carcinomas of the breast, bladder, and liver, we have examined a large number of tumors for genetic alterations of p57. Although no somatic mutation has been detected, we have found several normal variations in this gene, including four types of 12-bp in-frame deletions in the proline/alanine repeating domain, in which nearly 40 motifs, viz., 5'-CCGGCC-3', are tandemly repeated.

Nuclear magnetic resonance (NMR) analysis on the serum lipids of rabbits infected with Schistosoma japonicum: oxidative modifications of diene system in fatty chains.

Proton nuclear magnetic resonance (1H NMR) spectroscopy was used to characterize the oxidized products in the serum lipoprotein lipids (LPL) of rabbits infected with Schistosoma japonicum. The loss of bis-allylic and allylic methylenes proton peaks (2.7 and 2.0 p.p.m.) of unsaturated systems of the LPL and the appearance of the signals of the conjugated diene systems of hydroperoxide (5.43-6.45 p.p.m.) and epidioxide (2.45 p.p.m.) of the fatty chains of the serum demonstrated the lipids degradation associated with the Schistosoma infection.

[Discriminant analysis of quantification theory on prognostic factors of chemotherapeutic effects on advanced testicular cancer. East Japan Testicular Tumor Study Group].

Prognostic factors of chemotherapy against advanced testicular cancer were analysed in 33 cases studied by East Japan Testicular Tumor Study Group. In this study a discriminant analysis of quantification theory (a multivariate analysis) was adapted, taking 7 factors as comparative variables. The significant factors for complete tumor response were clinical stage, histology, and tumor markers (HCG-beta, AFP). Prognostic score was calculated in each case by quantification theory, which correctly discriminated the group with CR from that without CR, at a probability of 90.1%. The results of our study indicate that the outcome of chemotherapy on advanced testicular cancer may be predicted with probability, by patients' status and adopted treatment. It may enable one to make an adequate treatment schedule for each patient.

Transurethral resection in prostatic cancer.

Complications arising from transurethral and open subcapsular prostatectomy were studied in 121 patients with prostatic cancer and in 121 patients matched in age and prostate weight who had undergone prostatectomy for benign prostatic hypertrophy (BPH). After transurethral resection, cancer patients had a significantly longer hospital stay than did patients with BPH (P less than 0.01) and more had complications, such as perforation and bleeding. Compared to transurethral prostatectomy, open resection resulted in greater blood loss and more complications for the cancer patients. It is concluded that transurethral resection is as safe for most cancer patients as it is for patients with BPH, but the dangers of massive bleeding and dissemination of the cancer cells should not be overlooked.

Urinary tract infections in patients undergoing transurethral prostatectomy.

The incidence of urinary tract infections was determined in 1,660 patients undergoing transurethral prostatectomy. Preoperative infection was found in 25% of all patients and in 35% of the 276 patients aged 80 years or over. Of the 1,251 patients without a preoperative infection, 17% had postoperative infections. The incidence of new postoperative infection was significantly related to the duration of surgery and the weight of the resected prostate. The incidence of infection was higher in summer than in winter months.

Epididymitis after transurethral prostatectomy.

Transurethral prostatectomy was performed in 2,407 patients and open subcapsular prostatectomy in 308 patients. Postsurgical epididymitis developed in 1.0% of the patients undergoing transurethral resection and in 3.2% of the patients undergoing open resection (P less than 0.05). Factors associated with the incidence of epididymitis, such as prostate weight and operating time, were also associated with the incidence of urinary tract infection. Epididymitis was significantly associated with the presence of preoperative catheterization and postoperative urinary tract infection.

Comparison of transurethral and open subcapsular prostatectomy: relation to weight of the prostate.

The results of transurethral prostatectomy in 2,269 men and open subcapsular prostatectomy in 300 men were compared. The only significant differences between the two groups were in the duration of hospital stay (18.3 vs 26.2 days) and the number of days that the drainage catheter was indwelling (5.4 days in the transurethral and 10.9 days in the open surgery group [P less than 0.01, both comparisons]). Blood loss, the need for transfusion, the amount of blood transfused, and the duration of surgery, catheterization, and hospital stay were all related to prostate size. Transurethral resection was superior to open resection for prostates weighing less than 20 gm; prostates of 20 gm to 30 gm were the easiest to enucleate.

[Therapeutic effect of amoxicillin in the surgical field (author's transl)].

1. Amoxicillin was used for treatment of 15 cases of infectious diseases in the surgical field and for prevention of 4 cases of postoperative infection, and good result was obtained in all 19 cases. Especially in the latter 4 cases, amoxicillin showed good preventive effect. 2. Any side effect probably due to amoxicillin was observed in no case. 3. Amoxicillin at a daily dose of 1,000 mg (potency) exhibited sufficient effect in treatment of infectious diseases in the surgical field and in prevention of postoperative infection.
