Abstract
Using BrdU labelling-acridine orange fluorescence staining and the expression of PGK-1 isozymes, we attempted to clarify the pattern of X chromosome inactivation in bone marrow cells from adult female mice heterozygous for Searle's X-autosome translocation. The asynchronously replicating X chromosome was always the morphologically normal one, and neither of the translocated X chromosomes showed allocyclic behavior. Unexpectedly, a substantial proportion of the allocyclic X chromosome apparently finished replication earlier than any other chromosomes of the cell. This early replicating allocyclic X chromosomes was judged to be as genetically inactive as the late replicating one, since the Pgk-1b allele on the normal X was never expressed in bone marrow cells. Study of karyotypically normal females and females carrying Cattanach's insertion showed that the early replicating X chromosome is not just a feature of the Searle's translocation in the adult bone marrow cells and may be either paternal or maternal in origin. This type of allocyclic X chromosome deserves attention in assessing X chromosome inactivation in female somatic cells.

Abstract
A series of near-diploid embryonal carcinoma-like hybrid cells were obtained from polyethylene glycol mediated cell fusion between murine embryonal carcinoma cells (PSA-6TG1 or OTF9-63) having one X chromosome and thymocytes or bone marrow cells from female mice carrying Cattanach's or Searle's translocation. Prior to fusion with EC cells the somatic cells are presumed to contain only one active X chromosome. Following hybrid formation, the chronology of X chromosome replication and the expression of X-linked gene Pgk-1 indicated that all X chromosomes contributed by both parents were active in these hybrids. Experiments were performed to rule out the possibility that the hybrids were formed by fusion of EC cells with rare somatic cells in which both X chromosomes were active. Taken together the data indicate that within four days of fusion there is reactivation of the entire inactive X chromosome.

Abstract
The allocyclic X chromosome in early female mouse embryos undergoes DNA replication either late or early in the S phase. Earlier studies indicated that the early-replicating X chromosome is restricted to the trophectoderm and primitive endoderm cell lineages in which the allocyclic X is almost exclusively paternal in origin. There has been, however, no compelling evidence for the genetic inactivity of the early-replicating X chromosome and a shift from early to late replication or vice versa. The present study employing a combination of 3H-thymidine autoradiography and BrdU labeling-acridine orange fluorescence staining in day-6 female mouse embryos found that the early-replicating X chromosome can change directly into a late-replicating one. The activity state of the early-replicating X chromosome was examined by electrophoretic determination of the X linked enzyme, phosphoglycerate kinase (PGK-1), in tissues isolated from 6.0-day and day-8.5 Pgk-1a/Pgk-1b embryos. Only the maternally derived Pgk-1 allele was expressed in the proximal endoderm and extraembryonic ectoderm of 6.0-day and the chorion of 8.5-day embryos. Thus, the early-replicating, paternally derived X chromosome found in about 70%-80% of the cells in these tissues seems to be repressed like the late-replicating one.

Abstract
Polyethylene glycol-mediated cell fusion between the hypoxanthine phosphoribosyl transferase (HPRT) deficient XO mouse embryonal carcinoma cell line, PSA-6TG1, and thymus or spleen lymphocytes from the normal male WKA/Hok rat gave rise to 35 somatic hybrid cultures. Hybrid cells being products of either a 1 : 1 or a 2 : 1 fusion invariably had morphological characteristics of endodermal cells from early embryos. BrdU-acridine orange (AO) fluorescence microscopy revealed do novo appearance of a late or early replicating, presumably genetically inactivated, mouse X chromosome in a substantial proportion of virtually tetraploid (XXY) or hexaploid (XXXY) hybrid cells.

Abstract
alpha-Keto acids in human mixed saliva collected without stimulation were analysed by reversed-phase ion-pair high-performance liquid chromatography (HPLC). Several alpha-keto acids were found in saliva and their concentrations were: alpha-ketoglutaric acid (KGA), 221 +/- 142; pyruvic acid (PA), 7490 +/- 5600; alpha-ketoisovaleric acid (KIVA), 61 +/- 23; alpha-ketoisocaproic acid (KICA), 137 +/- 79; alpha-keto-beta-methylvaleric acid (KMVA), 41 +/- 19 nmol/dl (mean +/- SD, n = 40). Their levels proved to be lower than those in plasma, except that of PA. Their concentrations in saliva showed individual variation compared with those in blood.

Abstract
A karyotypic comparison between the blue fox and the silver fox revealed conservation of the chromosome arm as a unit, except for large heterochromatic blocks in 10 pairs of blue fox chromosomes and the complete absence of a common metacentric autosomal pair. This finding seems to indicate that their karyotypes evolved from a common ancestral karyotype, characterized by 70-76 acrocentric autosomes, mainly through a series of independent centric fusions.

Abstract
High-performance liquid chromatography of prostaglandins is developed in which a fluorescence reagent, 4-bromomethyl-7-acetoxycoumarin is used to perform the high-sensitivity detection. The reagent reacts with prostaglandins and related compounds to form the ester derivatives, which are separated using a reversed-phase system. Each labeled compound eluted from the column is successively hydrolyzed to the fluorescent coumarin derivative, and this fluorophore is introduced into a flow-through fluorometer. Prostaglandins can be determined in the range of at least 1 nmol to 5 pmol, and the detection limit is about 10 fmol. This system is applied to the analysis of prostaglandins in human seminal fluid.

Abstract
Karyotypes were analyzed in 44 cases of mouse lymphomas induced by continuous oral administration of N-nitroso-N-butylurea (NBU): 14 cases of C57BL/6JKok, 6 from LT/sv, 5 from MT/Hok, 2 from (AKR/MsHok x T1Ct)F1, 2 from (AKR/MsHok x CBA/H-T6Hok)F1, and 15 from the first backcross generation of (CBA/Hok x CBA/H-T6Hok)F1 to CBA/Hok. Thirty-six were thymic lymphomas (TLs) and the remaining 8 nonthymic lymphomas (NTLs). No chromosome abnormality was found in 8 NTLs, whereas modal cells were karyotypically changed in 13 TLs. Unlike the situation in NTLs, chromosomally abnormal cells were always present in the remaining 23 TL cases in which modal cells showed no apparent deviation from the constitutional host karyotype. A total of 31 independent karyotypic changes were identified in 26 cytogenetically abnormal major clones from 19 TLs. Although trisomy 15 was the most frequent karyotypic change, being present in 9 TLs, its incidence was substantially low compared with experimentally induced murine TLs so far reported. Furthermore, 6 of the 9 trisomy 15 clones clustered to (CBA x T6)F1 x CBA. Thus, it seems probable that the genetic background of the host animals has a profound influence upon the frequency of trisomy 15 in TLs.

Abstract
We have made a detailed study of the X-chromosome replication pattern during the period when X-inactivation is occurring in the mouse embryo. Our observations show unequivocal regionalization of the embryo with respect to the temporal X-chromosome. The switch from isocyclic to allocyclic replication occurs in the embryonic ectoderm at approximately 6 days of development and is random with respect to parental origin of the X-chromosome. In the extra-embryonic tissues, however, the switch to allocyclic replication has apparently occurred prior to 5.3 days of development and almost exclusively involves the paternally-derived X-chromosome. Since these findings are consistent with results obtained in biochemical studies of X-chromosome activity in female embryos, we conclude that there is a close temporal relationship between the cytogenetic and biochemical manifestations of the X-inactivation process. In addition, we have observed a pattern of early paternal X-chromosome replication, transitory in some cases, that is unique to extra-embryonic tissues. These results suggest that there may be some differences in the mechanism by which X-inactivation occurs in the extra-embryonic tissues as compared with the embryonic ectoderm.

Abstract
The effect of fatty acids and monoglycerides on barrier properties of liposomal membranes prepared from egg phosphatidylcholine was investigated. The incorporation of these lipids as liposomal membrane components induced the alteration of the permeability to less permeable liposomally entrapped drugs, sulfanilic acid and procainamide ethobromide (PAEB). Monoolein caused greatly increased permeability of both drugs and unsaturated fatty acids markedly enhanced the release rate of PAEB, while saturated fatty acids caused a small increase in the release rate. Electron spin resonance (ESR) investigation with 5-nitroxide stearic acid showed that fatty acids disordered the hydrophobic region of the lipid bilayer and the disordering effect of unsaturated fatty acids was greater than that of saturated ones. It was demonstrated that the incorporated fatty acids and monoglycerides interacted with the polar region of the membranes by ESR study with cholestane label and 1H-NMR study. These results indicated that the increase in the membrane permeability caused by fatty acids and monoglycerides associated with the disorder in the membranes' interior and the interaction of the incorporated lipid with the polar head group of phospholipid.

Abstract
Four spontaneous AKR leukemias (T67, T68, T70, and T74) with a modal chromosome number of 40 were transplanted serially to syngeneic mice in order to assess the significance of trisomy 15 and other karyotypic changes in the development of leukemia. In T67 and T70, the chromosomally normal cell disappeared completely or decreased considerably in frequency at the first passage in vivo. The karyotype of the modal cells changed continuously in T67 during transplantation, conserving trisomy 17, while the pseudodiploid cells with trisomy 15 and monosomy X were stable from the first to the seventh transplant generations of T70. In contrast to these results, the primary cell population of T68 and T74 with modal cells having a normal karyotype remained essentially unchanged throughout 7 or 15 transplant generations, despite the occurrence of aneuploidy, which included trisomy 15 or trisomy 17 in low frequencies. It is thus evident that the diploid cell is compatible with being leukemic and that neither trisomy 15 nor trisomy 17 is necessary for the initiation and progression of AKR leukemia, although the former was detected in three of four primary leukemias used for this experiment and in all four during transplantation.

Abstract
By means of a cytological technique involving 5-bromodeoxyuridine, acridine orange, and fluorescence microscopy, the asynchronously replicating, hence genetically inactivated, X chromosome was identified in 6- to 8-day embryos from female mice heterozygous for Searle's translocation T(X;16)16H (abbreviated as T16H) mated with either karyotypically normal males or males carrying Cattanach's translocation T(X;7)1Ct in order to analyse the way in which the total inactivation of the normal X is achieved in adult T16H heterozygotes. Embryos examined included 9 Xn/X(7);16/16, 3 X 16/Xn;16x/16, 12 X16/X(7); 16x/16, 5 X16/Xn;16/16, 8 X16/X(7); 16/16 and 2 Xn/Y; 16x/16/16. In these notations X16, 16x, X(7) and Xn represent Searle's X with the centromeric segment of the X, Searle's X with the centomeric segment of chromosome 16, Cattanach's X with insertion of a chromosome 7 segment, and normal X, respectively. The X(7) exerted no apparent effect upon embryonic development up to the 8th day of gestation and X chromosome inactivation. -- The asynchronously replicating X was the Xn in X16/Xn;16x/16 and X(7) in X16/X(7);16x/16 embryos except a small number of cells on day 6 (13/493) and on day 7 (1/886) in which almost the entire 16x replicated asynchronously. The X16, on the other hand, never showed replication asynchrony. That the X16 is indeed unable to become inactivated was indicated by the observation that the X16 as well as Xn or X(7) did not replicate asynchronously in Xn/X16;16/16 and X16/X(7);16/16 embryos X16-inactive cell lines, if occurring, should have been genetically less unbalanced than any other cell line in such embryos. It is highly likely therefore that the ultimate inactivation pattern in T16H heterozygotes has been accomplished by (1) the inability of the X16 to become inactive; (2) inactivation in favor of the Xn; and (3) rapid elimination of 16x-inactive cells. Severe growth retardatin and early death of X16/Xn;16/16 and X16/X(7);16/16 embryos having no inactive X suggested that functional X disomy is detrimental to embryogenesis. These embryos further indicated that the concurrence of at least two X chromosomal loci separated by the T16H breakpoint is necessary for the homologous X chromosome becoming inactivated.

Abstract
A total of 941 mouse blastocysts obtained from two types of crosses in which one of parents carried Cattanach's X/autosome translocation was studied cytogenetically by quinacrine mustard fluorescence. The rearranged X (Xt) and the normal X (Xh) were distinguished by size. Karyotype analysis was successful in 721 embryos, of which 205 were heterozygous for Cattanach's translocation. A single heterochromatic and brightly fluorescent X chromosome was identified in 154 metaphase spreads from 89 blastocysts consisting of 32--96 cells. The paternally derived X chromosome (Xp) was heterochromatic in 87% and 88% of the informative cells from the crosses XnXn x XtY and XtXn x XnY, respectively. This preferential choice of Xp at the blastocyst stage might have an important bearing upon the preponderance of cells with an inactive Xp in the chorion and yolk-sac splanchnopleure.

Abstract
Q-band chromosome studies were done in 3 molar conceptuses and their parents, with special attention to six pairs of chromosomes (No. 3, 13--15, 21, and 22) in which polymorphic variants occur frequently. Those six pairs of chromosomes were uniformly homomorphic in moles, whereas at least one of them was heteromorphic in both paternal and maternal cells. Closer analyses provided evidence strongly suggesting that the moles inherited two morphologically identical haploid sets from the father and none from the mother. Thus androgenesis seemed causally related to pathogenesis of complete hydatidiform moles.

Abstract
Cytogenetic observations were made on 6 cell lines (MOB-1, MOB-2, MOB-3, MSB-1, HPRS Line 1, HPRS Line2) originating from Marek's disease lymphomas and 2 clones (1104-B, 1104-X-5) of a cell line established from an avian lymphoid leukosis tumor. The modal chromosome number was within the diploid range in all the lines except HPRS Line 1 and HPRS Line 2, both of which had a mode at about 60. Karyotypes were grossly abnormal in 4 cell lines: trisomy for No. 1 in MOB-2; the heteromorphic No. 1 pair in MSB-1, and marker chromosomes derived from rearrangements involving No. 3 or No. 5 and unidentified elements in HPRS Lines 1 and 2. The MOB-1 line which had been characterized by cells with an apparently normal karyotype was completely taken over by cells with a heteromorphic No. 1 pair morphologically similar to the one found in MSB-1 by the 95th day of continuous growth in vitro. BUdR-acridine orange differential staining technique revealed, however, different banding patterns in these abnormal chromosomes.

Abstract
By means of a double labeling method with H3-thymidine and 5-bromodeoxyuridine, it was found that the X chromosome showed no sign of change from an allocyclic to an isocyclic state, or vice vers in 6.5- and 7.5-day mouse embryos. Thus, reversal of allocycly may not account for the predominance of cells with the paternally derived X chromosome inactive in the yolk sac and the chorion of the mouse embryo.

Abstract
In heterozygous carriers of the mouse reciprocal translocation T(14;15)6Ca, the frequency of nondisjunction involving the minute marker chromosome was 4.4% in the male and 22.2% in the female. The fate of gametes with unbalanced genomes derived from normal as well as abnormal meiotic disjunction in T6 heterozygotes was investigated on the basis of chromosome counts at metaphase II and karyotype analyses in early postimplantation embryos produced by backcrossing with chromosomally normal animals. Results obtained indicate that meiotic, gametic, and zygotic selection attributable to specific types of chromosomal imbalances is minimal, if any, by the late blastocyst stage. All zygotes with unbalanced genomes, except those with 20 normal pairs plus the minute marker, however, die off in the latter half of pregnancy. Therefore, the increased incidence of translocation trisomics among progeny of female as compared with male heterozygotes reflects the higher incidence of nondisjunction in primary oocytes than in spermatocytes.
