Abstract
A 23-year-old man was admitted to Osaka University Hospital with complaints of breast enlargement and defect of bilateral scrotal content. A gonad-like organ could be palpable at bilateral inguinal area and pubic hair was a female escutcheon in spite of complete male phenotype for both external genitalia and posterior urethra by retrograde urethrogram. Decreased serum value of testosterone and increased the serum value of estradiol and progesterone were found by endocrinological evaluation. Karyotype derived from skin fibroblast and peripheral lymphocyte was 46, XX and H-Y antigen was detected. Exploratory laparotomy disclosed uterus and bilateral ovotestis with epididymis, seminal vesicle and Fallopian tube. The patient received gonadectomy, hysterectomy and insertion of testicular prosthesis.

Abstract
A 25-year-old female with simple virilizing type of congenital adrenocortical hyperplasia due to 21-hydroxylase deficiency was treated surgically with masculinizing operations which consisted of two-stage procedures. The first procedure was chordectomy associated with excision of both gonads and female internal genitalia. Eleven months later, the second procedure consisting of urethroplasty and implantation of testicular prosthesis was performed. The postoperative course was successful in terms of urination and penile erection.

Abstract
To examine the use of interleukin 2 as a therapeutic agent for human renal cell carcinoma the peripheral blood lymphocytes derived from patients with renal cell carcinoma were grown in interleukin 2 and tested in a 4-hour 51chromium release cytotoxicity assay against autologous cultured tumor cells. Peripheral blood lymphocytes, which were cultured separately in medium alone, mitomycin C-treated tumor cells, 20 per cent interleukin 2 and tumor cells plus interleukin 2, were used as effector cells. In all patients neither peripheral blood lymphocytes in medium alone nor in mitomycin C-treated tumor cells could lyse their own tumor cells. However, in 5 of 7 patients peripheral blood lymphocytes grown in interleukin 2 regardless of the presence of mitomycin C-treated tumor cells were capable of causing 5.7, 9.4, 12.7, 36.1 and 52.5 per cent lysis at effector/target cell ratios of 25, 50, 50, 50 and 25, respectively. However, more significant cytotoxicity was not obtained by peripheral blood lymphocytes cultured with tumor cells and interleukin 2. These results suggest that interleukin 2 might become a useful agent for patients with renal cell carcinoma.

Abstract
The effect of monoclonal antibodies to fibronectin-binding acid polysaccharide (anti-FAPS) on differentiation of primary mesenchyme cells and spicule formation was examined in cultured embryonic cells isolated from the sea urchin, Hemicentrotus pulcherrimus. Spicule formation of micromere-derived cells was enhanced by anti-FAPS. The increase of spicule formation correlated with the increase of calcium uptake into micromere-derived cells and spicules. Furthermore, both spicule formation and calcium uptake were inhibited by calcium-channel blockers (verapamil, diltiazem and nicardipine) and divalent ions (manganese and cobalt). These results suggest that FAPS, a component of the blastocoelic extracellular matrix surrounding the primary mesenchyme cells, may regulate the level of calcium uptake and spicule formation.

Abstract
Clinical course and histological findings of 692 patients with bladder tumor were reviewed to reveal the statistics and clinical profile of carcinoma in situ and its related conditions in the urinary bladder. Primary papillary intraepithelial lesions were found in 83 cases (12.0%), whereas flat intraepithelial carcinoma was found in 16 cases (2.0%), 10 as primary and 6 as secondary tumors. In 35 cases (3.5%), the bladder lesion was flat and rather difficult to find by cystoscopy, and initially considered as chronic cystitis or flat carcinoma in situ. Post-operative histological diagnosis, however, revealed micro- or apparent invasion beyond the basement membrane. Thus they were tentatively classified as clinical carcinoma in situ. The result of the radical surgical treatments for the clinical carcinoma in situ was very poor with a rough 5-year survival of 19%. The management of primary or secondary flat intraepithelial carcinoma was carried out by radical surgery or bladder sparing operation followed by intravesical instillation of cytotoxic agents. The results of these procedures remain uncertain. Some confusion in terminology of carcinoma in situ is discussed and the term "flat carcinoma" was recommended to indicate carcinoma in situ and its related conditions.

Abstract
Isolated rat heart preparations were used to determine the effect of cardioplegia on myocardial metabolism during profound hypothermic (15 degrees C) ischemia. The hearts were grouped according to the components of cardioplegia and the mode of administration. The six groups were normokalemic (GI), calcium-containing hyperkalemic (GII), calcium-free hyperkalemic (GIII) and single dose (A), multidose (B). Following 120 min of ischemia, tissue ATP decreased from 25.4 +/- 2.2 to 10.3 +/- 2.7, 3.9 +/- 2.4, 4.1 +/- 1.2, 15.5 +/- 3.2, 14.5 +/- 2.4 and 20.0 +/- 2.7 (I-A vs II-A p less than 0.005, I-A vs III-A p less than 0.005, I-B vs III-B p less than 0.05, II-B vs III-B p less than 0.005), and tissue lactate increased from 9.6 +/- 1.5 to 163.4 +/- 12.0, 174.1 +/- 13.5, 166.8 +/- 21.3, 99.1 +/- 8.3, 102.6 +/- 12.2 and 83.5 +/- 9.3 (I-B vs III-B p less than 0.02, II-B vs III-B p less than 0.02) mumol/dry wt g, in GI-A, GII-A, GIII-A, GI-B and GII-B, respectively. The results of this study suggests that (1) potassium cardioplegia in a single dose does not prevent degradation of high energy phosphate (HEP) in the hypothermic arrested heart, (2) though multidose cardioplegia is effective in preserving HEP during ischemia, the extent of its effects varies with the composition, and (3) the omission of calcium is beneficial in GIK cardioplegia in terms of preserving HEP at the end of ischemia.

Abstract
The anti-tumor effect of twice a week instillation of 30 mg mitomycin C combined with 200 mg cytosine arabinoside dissolved in 30 ml saline was studied in 37 bladder tumor patients. Endoscopic or histological disappearance of the tumor was observed in 19 cases, average instillation being 16.4 times. Small (less than 1 cm in diameter), low grade, low stage and villous-surfaced tumors were more sensitive to this therapy. Further more, in the cases showing a complete response, frequency of the intravesical tumor recurrence significantly decreased compared with the cases showing no response. The clinical results of this therapy are compared mainly with those of TUR performed at our hospital, and the usefulness and clinical limitation of this kind of management in the treatment of bladder tumors are discussed.

Abstract
We investigated the occasional inaccuracy in the biochemical measurement of urine by comparing the values from untreated samples to those obtained following our experimental pre-treatment regimen, which prevents precipitation and dissolves visible crystals. Discrepancies were observed between some of the paired samples, especially with regard to calcium and uric acid (urate) concentrations. Moreover, considerable differences were recognized in fresh as well as stored urine specimens. Our findings demonstrate the need to develop accurate methods of processing urine for biochemical analysis with multichannel autoanalyzers.

Abstract
Analyses of hormone receptors in cytosols from 41 renal cell carcinoma specimens were performed by the dextran-coated charcoal technique, using estradiol, synthetic progestin R5020 and synthetic androgen R1881. Binding data were calculated according to the method of Scatchard. Of 41 renal cell carcinomas estradiol receptor was detected in 11, R5020 receptor in 11 and R1881 receptor in 13. No significant correlation between histopathological findings and hormone receptors was observed. Patients were classified into those positive and negative for receptors. The clinical response of endocrine therapy for 17 with advanced residual or metastatic lesions after nephrectomy was studied in regard to the survival rates. Although there was no complete or partial regression in tumor size, the survival rate of patients with 1 or more receptors was significantly higher than that of patients negative for receptors (p less than 0.01). In conclusion, hormonal manipulation in patients with renal cell carcinoma cannot induce an antitumor effect but seems to increase survival in patients with receptors.

Abstract
A case of stage IIB seminomatous tumor treated with the combination chemotherapy regimen of cis-platinum, vinblastin and bleomycin is presented. The patient was a 42-year-old man who was admitted to our hospital with the chief complaint of the right intrascrotal mass and edema in right lower extremity. Right radical orchiectomy was immediately performed under the diagnosis of testicular tumor. Histological diagnosis was pure seminoma. Paraaortic bulky metastasis and right hydronephrosis were found in the abdominal CT-scan. PVB therapy for initial treatment was started. After four courses of this therapy, retroperitoneal lymphadenectomy was performed. Because no live tumor cells were found histologically in any of the dissected material, complete response was considered to have been achieved by PVB therapy. Considering the poor survival and high relapse rate of advanced seminomatous tumor treated with radiotherapy, this PVB therapy should be the initial treatment for this disease.

Abstract
Ten patients with advanced transitional cell carcinoma were treated with the combination chemotherapy (CISCAF) consisting of cis-platinum (CDDP), cyclophosphamide (CPM), adriamycin (ADM) and 5-fluorouracil (5-FU). There were 8 males and 2 females with a median age of 57 years (range 33-76). Prior to this chemotherapy, all primary lesions were resected surgically; one patient received irradiation, one interferon. CDDP (15 mg/m2) with mannitol diuresis and ADM (7 mg/m2) were given daily for 5 days. CPM (200-300 mg/m2) was given on day one, and 5-FU (200-300 mg/m2) on day 2. Courses were repeated every 3-4 weeks for 3 courses and later every 2 months. All patients were evaluable for toxicity and 9 for response. There were 3 (33%) partial and 2 minor responses. Survival difference between responders (PR + MR) vs non-responders (NC + PD) was significant during the 30-120 days of observation, but not significant throughout the whole period (generalized Wilcoxon test). The overall toxicity due to chemotherapy was generally mild, except for one irreversible nephrotoxicity and one gastric hemorrhage treated surgically.

Abstract
Purification and characterization of mitochondrial malate dehydrogenase [EC 1.1.1.37] from unfertilized eggs of the sea urchin, Anthocidaris crassispina, are described. The purification method consisted of dextran sulfate fractionation, Blue Dextran Sepharose chromatography, Phenyl-Sepharose hydrophobic chromatography and DEAE-cellulose chromatography. The enzyme was purified 771-fold with a 7% yield from the crude extract. The purified enzyme appeared homogeneous on polyacrylamide gel electrophoresis under both native and denatured conditions. After incubation at 45 degrees C for 50 min, the enzyme lost about 90% of its activity. In the presence of NADH, however, the enzyme was protected against the heat denaturation. The native enzyme had a molecular weight of about 65,000 and probably consisted of two identical subunits. In the reduction of oxaloacetate with NADH, a broad optimum pH ranging from 8.2 to 9.4 was found with 50 mM Tris-HCl and glycine-NaOH buffers. Sodium phosphate buffer apparently activated the enzyme. The apparent Km values for oxaloacetate and NADH were 19 microM and 30 microM, respectively. The optimum pH for malate oxidation with NAD+ was 10.2 in 50 mM NaHCO3-Na2CO3 buffer. The apparent Km values for malate and NAD+ were 7.0 mM and 0.6 mM, respectively. Zinc ion, sulfite ion, p-chloromercuriphenylsulfonate and adenine nucleotides strongly inhibited the enzyme.

Abstract
Cell-mediated immunity was studied by measurement of lymphocyte response to autologous tumor cells in 19 surgically treated patients with histologically proved (mixed lymphocyte tumor cell culture) renal cell carcinoma. Tumor stage was low in 9 patients and high in 10, while grade was low in 11 and high in 8. Of 8 patients in whom a positive lymphocyte response was detected 6 had high and 2 had low stage tumors (p less than 0.05), while the grade of disease was low in 7 and high in 1 (p less than 0.05). Furthermore, the more advanced and undifferentiated the tumor the more significant the decrease in lymphocyte response (p less than 0.05). Lymphocyte response was positive in 5 of 8 patients with low stage and low grade tumors but negative in 7 with high stage and high grade disease. However, no correlation between the lymphocyte response and the degree of microscopic lymphocytic infiltration in and around the tumor was found. This study confirms that the specific immunological defense mechanism of patients with renal cell carcinoma against the tumors remains well at an earlier stage of tumor development, especially in cases with well differentiated malignancy, and showed attenuation in parallel with pathological spread or in poorly differentiated tumors.

Abstract
Analysis of the ribosomal proteins in sea urchin eggs by two-dimensional polyacrylamide gel electrophoresis revealed postfertilization changes in the proteins of both the small and the large subunits. Five egg-ribosomal proteins (S7, S16, S19, L19, L31) appeared to undergo rapid changes to the corresponding embryo-specific proteins. These changes were completed within 30 min after fertilization, and identical electrophoretic patterns were observed among the different developmental stages of embryos. One of the five proteins, S7, showed an increase in the phosphorylated form. The remainder showed qualitative shifts to the corresponding embryo-specific proteins; however, peptide map analyses revealed the existence of common structural units between the corresponding proteins. These modifications were observed in the three species of sea urchin studied (Pseudocentrotus depressus, Hemicentrotus pulcherrimus and Anthocidaris crassispina), except in the case of one protein (L31). Purification of ribosomes by different procedures based on high-salt treatment gave the same results with respect to the egg-specific and embryo-specific proteins.

Abstract
Sea-urchin fibronectin from the ovary of the sea urchin Pseudocentrotus depressus bound to gelatin, fibrin and fibrinogen. After mild digestion of the protein labelled with 125I, a 195 000 Da domain was observed. Sea-urchin fibronectin was aggregated by spermine (1 mM) at neutral pH. When the concentration of spermine was decreased or increased, the aggregation was diminished. The addition of 1 M-NaCl or 4 M-urea inhibited the spermine-induced aggregation. Sea-urchin fibronectin mediated the spreading of baby-hamster kidney cells on the plastic surface.

Abstract
The cytochrome system in eggs and embryos of the sea urchin, Hemicentrotus pulcherrimus, was investigated. Difference spectra of the mitochondrial fraction demonstrated the presence of a complete cytochrome system in unfertilized eggs. Cytochrome levels and the activities of respiratory enzymes were measured in crude extracts of eggs both before and after fertilization. Unfertilized eggs contained cytochromes aa3, b, and c + c1 in a ratio of 1.0:1.8:0.7. Gastrulae contained almost the same amount of cytochromes aa3 and b as unfertilized eggs. However, the amount of cytochrome c + c1 in gastrulae was 1.5 times greater than that in unfertilized eggs. The activity of cytochrome oxidase remained unchanged during development. No cytochrome oxidase inhibitor was found in unfertilized eggs. Both antimycin A-sensitive and insensitive NADH-cytochrome c reductase activities increased during development. The activity of succinate-cytochrome c reductase increased during early development, reached a temporary plateau, and then declined at the pluteus stage. These results are discussed in relation to the increase of respiration during early development.

Abstract
A protective effect of coenzyme Q10 on the ischemic and reperfused myocardium was investigated in the isolated working rat heart preparation. Rats were treated intraperitoneally with 30 mg/kg coenzyme Q10, daily for 7 days. The controls were given the same dose of the vehicle. After 25 min of equilibration the hearts were made totally ischemic at 35.5 degrees C for 30 min, arrested with high potassium cardioplegic solution immediately after aortic cross clamping. The recovery of cardiac power in the coenzyme Q10 pretreated group was significantly (P less than 0.05) better than that in vehicle pretreated group. Creatine phosphokinase (CPK) release during reperfusion was significantly (P less than 0.05) reduced by the pretreatment of coenzyme Q10. Tissue analysis for high energy phosphate compounds revealed no significant difference between the two groups. Tissue lactate content at 30 min of ischemia was significantly (P less than 0.001) lower in the coenzyme Q10 pretreated group. These results suggest that pretreatment with coenzyme Q10 is effective for reducing ischemic injury caused by aortic cross clamping.

Abstract
The circulating anti-RCC cytotoxic antibodies of eighteen RCC patients, preoperatively, and one inoperable case were studied by 51Cr release CDC and ADCC assays, using the cultured human RCC cell line, OUR-10. Circulating cytotoxic anti-RCC antibodies were detected in eight patients as CDC antibodies. The patients with a low pathological grade had a significantly higher percentage (P less than 0.05) of positive antibody responses.

Abstract
Ribosomal proteins from unfertilized eggs of three sea urchin species. Pseudocentrotus depressus, Hemicentrotus pulcherrimus, and Anthocidaris crassispina, were analyzed. Species-specific differences were observed in the profiles of large subunit proteins on two-dimensional slab gels, though the number of ribosomal proteins and the molecular weights of their counterparts were the same. The small subunit proteins revealed similarities in the electrophoretic profiles and in the phosphorylation patterns among these three species.

Abstract
Ribosomal proteins from the eggs of sea urchin, Pseudocentrotus depressus, were analyzed by two-dimensional polyacrylamide gel electrophoresis (PAGE) and sodium dodecyl sulfate (SDS)-PAGE. Thirty different proteins including three acidic proteins were detected in the small subunit. The large subunit was found to contain at least 43 different proteins, 42 basic and one acidic. The ribosomal proteins from the small subunit have molecular weights ranging from 11,900 to 51,700 (average molecular weight: 25,600). The molecular weights of the large subunit proteins range from 12,700 to 76,300 (average molecular weight: 28,700).

Abstract
We studied retrospectively 155 patients with calcium oxalate urolithiasis. The patients were divided into 3 groups: 1) those with calcium oxalate monohydrate, 2) those with calcium oxalate dihydrate and 3) those with mixed calcium oxalate monohydrate and dihydrate. Various differences were noted between patients with calcium oxalate monohydrate and those with calcium oxalate dihydrate, with respect to stone characteristics, spontaneous passage of stones, stone recurrence and multiple occurrence. Most important, we noted that patients with calcium oxalate dihydrate had more stone recurrences than patients with calcium oxalate monohydrate.

Abstract
A standard method for determining mutant frequencies per survivor was used to study the detailed kinetics of reverse mutations of Ames tester strains of Salmonella typhimurium induced by UV and by 4NQO. After UV irradiation, strain TA1538 was non-mutable, but its plasmid-containing derivative TA98 was mutable, whereas TA1535 was mutable and its plasmid-bearing derivative TA100 was about 10-fold more mutable. After treatment with 4NQO, TA98 was less mutable than TA1538, whereas TA100 was more mutable than TA1535 by a factor of 10-50. TA1537 was slightly less mutable than TA1535 by either UV or 4NQO. The differential mutabilities of these strains are briefly discussed in relation to the "hot spot" base sequences for reversion and the nature of DNA damage caused by UV and 4NQO.

Abstract
Two genomic variants of vaccinia virus isolated from serially propagated stocks were used to demonstrate marker rescue. The smaller (S variant) virus contains a 6.3 megadalton (MDal) deletion of unique DNA sequences present in the 123-MDal larger (L variant) virus. The deletion was mapped at 6.85 MDal from the left terminus of the genome, just outside of the inverted terminal repetition. Rescue of the unique deleted DNA sequences by infectious S variant virus was obtained in CV-1 cells by using the calcium orthophosphate precipitation technique of intact or restriction endonuclease-treated L-variant DNA. Restriction fragments that overlapped the deletion allowed marker rescue, but restriction of the L-variant DNA within the unique deleted sequences gave negative results. Restriction endonuclease analysis of the DNA obtained from twice-plaque-purified recombinant virus derived from the rescue of overlap donor fragments gave a restriction pattern identical to that of L-variant virus, indicating that the donor DNA was inserted into the rescuing virus by double recombination. No amplification of the unique sequences was observed from intact L-variant DNA in the absence of infectious S-variant virus, suggesting that deproteinized vaccinia DNA is noninfectious and that the donor DNA was neither integrated into the host DNA nor present as an episomal structure. By using 1 microgram of intact L-variant DNA per CV-1 monolayer in a 6-cm Petri dish, approximately 1--5% of the plaques contained the L-variant genotype, and the dose--response curve was essentially linear from 0.1 to 2 microgram of DNA.

Abstract
1. The behavior of H4-lactate dehydrogenase in a solution of sodium chloride was studied with respect to its molecular weight. The molecular weight decreased as the concentration of sodium chloride increased. 2. On a controlled-pore glass column equilibrated by 0.5 M soldium chloride, H4-lactate dehydrogenase was found to have mol. wt 77,500. 3. In a low salt column (0.1 M sodium chloride or less), on the other hand, the molecular weight was found to be about 135,000. 4. Salt concentration dependent association-dissociation system of the enzyme was also observed by the sedimentation equilibrium method.

Abstract
The effects of the umuC36 mutation on the induction of base-change and frameshift mutations were studied. An active umuC gene was necessary in either the uvr+ strains of Escherichia coli K12 for UV- and X-ray-induced mutations to His+, ColER and SpcR, which are presumably base-change mutations, but it was not essential for ethyl methanesulphonate or N-methyl-N'-nitro-N-nitrosoguanidine-induced His+ mutations. In contrast, only 1 out of 13 trp- frameshift mutations examined was UV reversible, and the process of mutagenesis was umuC+-dependent, whereas a potent frameshift mutagen, ICR191, effectively induced Trp+ mutations in most of the strains regardless of the umu+ or umuC genetic background. These results suggest that base substitutions are a major mutational type derived from the umuC+-dependent pathway of error-prone repair.

Abstract
In vitro cultivated cells derived from normal human renal cortex were characterized morphologically and biochemically. Although the epithelial monolayer was composed of heterogeneous cells, it included cells with a surface structure similar to microvilli as well as some resembling the desmosome between neighboring cells. Enzymatic studies revealed a marked decrease in alkaline phosphatase activity, and the activity of gamma-glutamyl transpeptidase was also reduced to about one-fifth of that in the original tissue. The electrophoretic mobility of the enzyme was not identical with that of normal kidney or of the novel enzyme in renal neoplastic tissue. Lactate dehydrogenase activity was similar to that of normal kidney tissue but the isozyme pattern was completely inverted. These cells responded to the addition of 10 ng per ml of parathyroid hormone in culture medium and there was a 33 fold increase in intracellular cyclic adenosine monophosphate. Estrogen specific binding protein was not detectable in the monolayer cells. These results clearly indicated that the biologic transformation observed in the cultivated normal cells was not attributable to simple fetalism or dedifferentiation, but was a more complicated process.
