Abstract
The chromosome constitution of peripheral blood lymphocytes from nine cases of B-cell chronic lymphocytic leukemia and one case of B-cell prolymphocytic leukemia were studied at diagnosis following stimulation by B- and T-cell activators. Chromosome analysis with banding techniques revealed an extra chromosome 12 (trisomy 12) in 4 B-cell chronic lymphocytic leukemia cases and complicated abnormalities, i.e., trisomy 12, 6q-, 14q+, and a translocation between chromosomes 6 and 12, [t(6; 12)] in the prolymphocytic leukemia case. These findings suggest that trisomy 12 is a prototypic change in B-cell leukemia, particularly in B-cell chronic lymphocytic leukemia. Based on sister chromatid exchange studies of unstimulated lymphocytes, it appears that some leukemia cells with a normal karyotype not only divide but also proliferate in vitro.

Abstract
To evaluate the hemodynamic effects of dibutyryl cyclic AMP (DBcAMP) in congestive heart failure (CHF), right-sided cardiac catheterization was performed in 11 patients with CHF, and hemodynamic variables were investigated before and after infusion of various doses of DBcAMP at a rate of 0.025 to 0.2 mg/kg/min (mean 0.14 +/- 0.077 [standard deviation]). DBcAMP reduced total systemic vascular resistance index from 3,171 +/- 1,158 to 1,880 +/- 554 dynes s cm-5 X m2 (mean +/- standard deviation) and pulmonary arterial end-diastolic pressure from 23 +/- 13 to 20 +/- 11 mm Hg, and increased cardiac index from 2.24 +/- 0.60 to 3.41 +/- 1.02 liters/min/m2. Mean arterial blood pressure decreased from 91 +/- 14 to 84 +/- 13 mm Hg, and heart rate increased from 91 +/- 16 to 99 +/- 13 beats/min. The increase in cardiac index was accompanied by a proportional decrease in total systemic vascular resistance index in all patients except 1. In 8 patients the decrease in pulmonary arterial end-diastolic pressure was accompanied by an increase or no change in the left ventricular stroke work index. In 6 patients, DBcAMP was given in incremental doses of 0.05, 0.1, and 0.2 mg/kg/min every 20 minutes, and 5 of 6 patients tolerated the full dose and showed dose-related hemodynamic changes for the incremental doses of DBcAMP. These data suggest that DBcAMP has powerful vasodilating effects on resistance vessels in patients with CHF; hence, it can be a useful vasodilating agent for treatment of CHF.

Abstract
A 38-year-old woman with coronary arterial aneurysm, which resulted in myocardial infarction, was reported. By coronary arteriography, an aneurysm of the left anterior descending branch was found, but no arteriovenous shunt could be revealed. The patient has neither clinical history of severe febrile inflammatory disease nor any coronary risk factors. The etiology of her coronary arterial aneurysm was considered to be congenital. The patient underwent aorto-coronary saphenous vein bypass graft surgery successfully. We believe that this is the first case report in Japan on congenital aneurysm of the coronary artery without arteriovenous fistula, which was diagnosed during life by coronary arteriography.

Abstract
Silicon dioxide lamellar gratings fabricated by a new technique combining holographic exposure and reactive ion-beam etching are found experimentally to be appropriate to and useful for synchrotron radiation spectroscopy. Methods to improve edge roughness and to control the land-to-groove width ratio are also investigated. The fabrication technique developed here is relatively simple in comparison with the ruling technique which needs delicate control. Therefore, it is a promising way to employ these bakable original gratings for synchrotron radiation spectroscopy.

Abstract
In an attempt to clarify the regulatory mechanism that accounts for the shift of protein A24 in the mitotic cycle, we demonstrated the existence of an enzyme, provisionally termed isopeptidase, that cleaves A24 stoichiometrically into histone H2A and ubiquitin. Properties of this enzyme are (i) most eukaryotes, including mammals, amphibia, chicken, and yeast, contain isopeptidase in the cytoplasm; (ii) a significant increase in enzyme binding to chromatin occurs when cells enter mitosis; (iii) Escherichia coli does not contain isopeptidase; (iv) isopeptidase has a molecular weight of 38,000; (v) at an ionic strength that induces globular conformation of H2A, isopeptidase activity is repressed; (vi) a SH group is an essential cofactor; and (vii) most divalent cations (except Mg2+ and Ca2+) are inhibitory. In view of the stoichiometric conversion of A24 into H2A and ubiquitin by isopeptidase in vitro, A24 probably contains a Gly-Gly dipeptide in isopeptide linkage but no other intervening polypeptides. Since ubiquitin in various eukaryotes binds to protein other than H2A, and is proteolytically released, isopeptidase probably acts on isopeptide bonds in general and not uniquely on those of A24. Inasmuch as isopeptidase is present throughout the cell cycle, the level of A24 in chromatin appears to be controlled by a balance between isopeptidase and an as yet unestablished H2A-ubiquitin ligase.

Abstract
The preferential association of choriocarcinoma with complete moles has long been recognized. In fact, of all forms of pregnancy that lead to choriocarcinoma, the risk associated with hydatidiform moles is 2000 to 4000 times greater than that of normal pregnancy or abortion. In order to corroborate the cell lineage between hydatidiform moles and choriocarcinoma, we investigated the chromosomal constitution and polymorphisms in the latter cells. Three choriocarcinomas from three women with a previous history of hydatidiform moles were examined chromosomally. Two hundred thirteen cells were analyzed for their chromosome number by conventional Giemsa staining; karyotyping of 33 cells with Q- and C-banding revealed 13 kinds of structural abnormalities unequivocally identified as of clonal origin. Two cases exhibited involvement of the long arm of chromosome 1 in rearrangements. Complete homozygosity and exclusive inheritance of a paternal genome would be expected if the tumor arose from a preceding molar pregnancy. However, the heterozygosity observed in choriocarcinoma cells suggests no common cellular lineage with complete moles; the latter originate through fertilization of an "empty egg" by a haploid sperm, followed by duplication of the chromosomes. Several possibilities have to be considered for the origin of choriocarcinomas, since it seems unlikely that alterations in the paracentric areas of the marker chromosomes occurred during tumor development. One possibility is that moles which are characterized by heterozygosity may transform into choriocarcinomas. Another possibility is that such tumors may originate from trophoblasts of the conceptuses rather than from moles.

Abstract
Nifedipine, the Ca++ antagonistic coronary vasodilator, was administered by oral, sublingual and enema routes. 1) In 6 severe hypertensive patients (systolic pressure greater than or equal to 200 mmHg, diastolic greater than or equal to 120 mmHg), nifedipine, administered orally, induced prompt and reliable fall of arterial pressure (systolic pressure: -28% of control level, diastolic: -27%). 2) In 10 patients with hypertensive emergencies, including malignant hypertension, intracranial bleeding, hypertensive encephalopathy and acute hypertensive heart failure, sublingual and enema administration of nifedipine were performed with excellent hypotensive efficacy. 3) Pressure began to fall within 5--15 min, 30 min and 30--60 min after sublingual (or dissolved), enema and oral (capsule), respectively, and reached its lowest levels in the next 10--20 min. The fall of pressure lasts for 2--4 hours. 4) In the combination of nifedipine with alpha-methyldopa, antihypertensive response in short-term was increased about +11% over nifedipine alone and lasted for 8 hours. In combination with beta-blocker (propranolol), hypotensive efficacy increased +39% over nifedipine alone, but the effective duration of this combination was the same as nifedipine alone. 5) Side effects, including dryness of the mouth and burning sensation in face and legs, were observed in few patients.

Abstract
Rat liver glutathione S-transferases (RX: glutathione R-transferase, EC 2.5.1.18) were found to adsorb S-carbamidomethyl glutathione linked to Sepharose CL-4B via lysyl or aliphatic diamine spacers of various carbon chain lengths (-NH-(CH2)n-NH-, n = 2, 4, 5, 6, 8 and 10). Proteins were eluted specifically by reduced glutathione. The affinity of the enzymes for the adsorbent increased with increase in the carbon chain length of aliphatic diamine spacers used. Adsorbent having a free carboxyl group within the spacer moiety had high capacity and was specific for glutathione S-transferases. The transferases were specifically eluted from the column in high yield by low concentrations of glutathione. Enzymes purified by the lysyl spacer adsorbent were homogeneous in sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis and contained most of the hepatic glutathione S-transferase isozymes in isoelectric focusing. Oxidized glutathione and S-methyl glutathione were equally effective as reduced glutathione in eluting glutathione S-transferases from the adsorbent, but gamma-glutamylcysteinylglycineamide or gamma-glutamylcysteinylglycine-1-methyl ester were not effective. These data suggested that the free carboxyl group of glycyl moiety of glutathione might also be important for the specific binding of the transferases to this adsorbent.

Abstract
Fusion of fresh lymphocytes from a Bloom syndrome (BS) patient with those of normal subjects or a BS heterozygote resulted in complete normalization of the frequency of sister chromatid exchanges in the chromosomes of BS cells. This normalization took place by the first mitosis in hybrid cells. In contrast, cultivation of BS lymphocytes with those of normal subjects or the BS heterozygote had no effect on sister chromatid exchanges. The cell fusion experiments suggest that the normalization on the sister chromatid exchanges. The cell fusion experiments suggest that the normalization of the sister chromatid exchange frequencies in BS cells can be achieved by factors conserved in the cells of various mammalian species. These findings are compatible with the concept that BS is a recessive genetic mutation at regulatory levels of the DNA repair function.

Abstract
Mechanical and enzymatic disaggregation procedures have been utilized for the preparation of materials suitable for chromosome examination of tissues from various kinds of solid tumors. A great number of the cells disaggregated with the latter procedure were observed to attach to the bottom of culture flasks after 2 days in vitro; cells obtained with the former method were not attached. In general, the enzymatic procedure yielded a significantly larger number of viable cells that would undergo mitosis after short term culture and considerably improved the quality of banding as compared to the mechanical method. However, there were no significant differences among the basic karyotypes observed in the cells obtained by the mechanical approach versus those seen following the enzymatic method. This evidence, together with the high success rate of karyotyping in the enzyme-treated preparations, suggest that this should be the procedure of preference for cytogenetic examination of various tumors, particularly where in the past karyotypic examination has been very difficult, e.g., the early stages of tumor development.

Abstract
Cytogenetic studies were performed in 12 papillary serous adenocarcinomas of the ovary. Of the more than 19 clonal structural chromosome abnormalities observed in these cancers, 6q- and 14q+ were found to be the most frequent. Both markers coexisted in the cells of eight cases; in the other four cases, either a 6q- or 14q+ was present. In at least six cases, the additional segment on the long arm of chromosome 14 appeared to originate, on the basis of the chromosomal quantity and fluorescence pattern, from the missing part of chromosome 6. This suggested that the 6q- and 14q+ markers had arisen as a result of a reciprocal translocation at Bands q21 and q24, respectively, i.e., t(6;14)(q21;q24). However, it is uncertain in the remaining six cases whether an identical type of translocation was responsible for the formation of the markers. Thus, abnormalities involving chromosomes 6 and 14 seem to be specifically associated with papillary serous adenocarcinoma of the ovary.

Abstract
To determine the structural basis of chromatin assembly that leads to chromosome formation in mitosis, crosslinks were introduced by formaldehyde between contiguous components within chromosomes. Crosslinked stable products were then observed by electronmicroscopy after non-crosslinked portions were briefly digested by trypsin to unfold chromosomes.--When the DNA-histone crosslink was the primary product, trypsin readily unfolded the whole chromosome structure while preserving the 250 A unit chromatin fiber intact; only a single unit fiber was tracked within the centromere region connecting the arms of each chromatid. When a histone polymer was formed by a prolonged formaldehyde crosslinking, trypsin digestion gave rise to chromatin fibers interacting with others at certain distances, and the typical chromosome structure remained unchanged. Regardless of the degree of crosslinking, there were neither thick supercoiled unit fibers nor proteinaceous cores.--These results suggest that the fiber connection may represent, to some extent, the interacting sites of folded chromatin fibers in situ within chromosomes, and also that the 250 A unit fibers are the sole, highest structural basis in chromosomes. Since virtually no appreciable histone digestion took place in the crosslinked chromosomes, the observation that even after DNA-histone crosslinking the fiber interacting sites were accessible to trypsin preferentially over other portions, may be consistent with our recent results that the exposed, lysine-rich tails of histones represent such interacting sites.

Abstract
Comparative metabolic fate of labelled chromium chloride and sodium chromate and interaction of these compounds in the rat liver and blood were investigated after their oral and intravenous administration. Gastrointestinal absorption of both compounds was below 1% of the oral dose, but trivalent chromium showed higher radioactivity than the hexavalent form in rats (biological half-life: CrCl3 91.79 days, Na2CrO4 22.24 days). The higher residual activity of the trivalent chromium was also observed after intravenous administration. Both forms of chromium were excreted more in the urine via the kidney than in the intestinal tract after intravenous administration. When 51CrCl3 and Na251CrO4 were injected into rats, in the time-distribution patterns of 51Cr in the organs, a significant difference was shown between oxidation states of the two compounds, especially in subcellular fractions of the liver and blood constituents. This significant difference mainly observed in the rat blood came from the fact that trivalent chromium possessed a high binding activity for transferrin in plasma, while hexavalent chromium was permeable into red cells and bound with hemoglobin.

Abstract
Hemodynamic response of nifedipine in 11 patients with congestive heart failure was examined. Thirty minutes after sublingual administration of nifedipine, CI and SVI were increased together with a decrease in PAEDP and TSVRI. The increase in CI was proportional to the decrease in TSVRI. Twenty-four hours after continuous administration of nifedipine, however, six of 11 patients did not show the improvement of left ventricular function. These results indicate that sublingual administration of nifedipine is effective in the short-term therapy of the patients with a markedly decreased cardiac output and an increased systemic vascular resistance.

Abstract
The pituitary thyrotrophs and thyroid follicular cells of rats were studied by electron microscopy and morphometric analysis at 5, 10, 20, 30 and 60 min after intravenous injection of 200 microgram of thyrotropin releasing hormone (TRH) and at 10 min after injection of 10 microgram TRH. Multiple granule extrusions in a group were often observed around the pituitary thyrotrophs at 5, 10 and 20 min after administration of 200 microgram TRH, as well as at 10 min after injection of 10 microgram TRH. The number of released granules reached its maximum at 10 min after 200 microgram TRH injection, but the total number of secretory granules in the cytoplasm of thyrotrophs did not show any significant variation throughout the experimental period. Percent area of the rough endoplasmic reticulum indicated the maximum value at 20 min and that of the Golgi apparatus at 10 min. These findings suggest that TRH stimulates the thyrotroph and accelerates synchronously the secretion as well as the synthesis of TSH. In the thyroid follicular cells after 200 microgram TRH injection, numerous small vesicles which might be secretory granules were found in the apical cytoplasm at 5 and 10 min. Pseudopod formation on the luminal surface and accumulation of colloid droplets and lysosome-like granules in the apical cytoplasm were most frequently observed at 20 and 30 min. The value of the mean ratio of the diameter of the colloid lumen to the cell height of follicular cells in the thyroid follicles of all experimental animals stimulated with TRH decreased much more than that of the control animals. This value may indicate the increased activity of follicular cells to reabsorb the colloid.

Abstract
In order to develop the investigations into photobiogenesis of vitamin D3, a rapid and precise method for the determination of the vitamin in rat skin was established by using high-performance liquid chromatography (HPLC). The proposed method included saponification of small pieces of rat skin, extraction of the unsaponifiable matter and application to HPLC using "Zorbax SIL" (straight-phase) as an adsorbent and 0.5% isopropanol in n-hexane as a mobile phase. The applicable lower limit of the method was 2ng of vitamin D3/cm2 of subcutaneous tissue-removed skin and it was possible to assay a concentration higher than 2 ng/cm2. The proposed method was applied to determine the content of vitamin D3 in rat skin obtained from in vivo and in vitro irradiation experiments. In the in vitro experiment, the yield of vitamin D3 increased in proportion to the irradiation time. On the other hand, the yield in the in vivo experiment showed a proportional increase similar to the in vitro experiment until 60 min irradiation, while a nearly constant value was obtained by irradiation for longer than 60 min. When the rat skin obtained from the in vitro experiment was irradiated with monochromatic UV rays in the range s60-350 nm, the most effective wavelength for the formation of vitamin D3 was confirmed to be 303 nm, which differs from the result obtained from the experiment in a test tube (295 nm). Moreover, the yield of vitamin D3 by irradiation with UV rays below 288 nm was extremely low, which again differed from the results of a test tube experiment. These differences were thought to be due to the filter effect of the malpighian layer in the epidermis of rat skin.
