    Notes: Seed longevity varies considerably in cultivated rice (Oryza sativa L.), but the underlying genetic mechanism of longevity has not been well elucidated. Quantitative trait loci (QTL) that control seed longevity after various periods of seed storage were sought using recombinant inbred lines derived from a combination involving ‘Milyang23’(Indica-type) and ‘Akihikari’ (Japonica-type). In all, 12 QTLs for germination and normal seedling growth were detected as indices of seed longevity on chromosome 7 (one region) and chromosome 9 (two regions) in treated seeds that had been stored under laboratory conditions for 1, 2 or 3 years.‘Milyang23’ alleles of all QTLs promoted germination and normal seedling growth after all durations of storage. These QTL regions were detected repeatedly in more than one seed condition. Therefore, we infer that these regions control seed longevity.

    Notes: 1. The ability of verapamil to induce a contractile response in skeletal muscle was investigated using the canine isolated, blood-perfused diaphragm preparation.2. Verapamil-induced contracture was characterized by a biphasic increase in muscle tension consisting of an initial phasic and subsequent tonic contracture.3. The second tonic component of the verapamil-induced contracture was inhibited by procaine, but procaine had no effect on the initial phasic contracture.4. Verapamil potentiated both KCl- and caffeine-induced contractures during the second tonic stage. This action might be explained by enhancement by the drug of availability, or by an increased sensitivity of the contractile machinery to calcium liberated by membrane depolarization or by the calcium-induced calcium release mechanism.5. The second tonic component of verapamil-induced contracture was much less than the initial phasic component. It seems, therefore, that the calcium release induced by the procaine-resistant process is the principal action of verapamil in inducing contracture in skeletal muscle.

    Notes: We have deqeloped a para-carotid approach for internal jugular cannulation which utlizes only the carotid artery as a landmark. This technique allows us to locatedhe puncture site regardless of an individual patient's physical, skeletal or postural variations. This study was undertaken in the period from January 1979 to June 1980 on 456 consecutive patients in a wide range of age groups and various clinical conditions. The overall success rate was 96.1%. The only complications encountered during our study were Five carotid artery punctures with formation of two haematomas.

    Three-Dimensional Vasculature of the Bovine Liver (2005)

    Notes: To clarify anatomical distribution of Fasciola infection, the vascular and ductal architectures of the liver were studied by means of corrosion cast technique using synthetic resin. The arteria hepatica propria (AP) passes as the arteria gastroduodenalis (AG); AP becomes the left trunk after the porta hepatis; AP passes on the right side of vena porta communis (VPC) and projects AG while curving in a U-shape below the portal vein. Hepatic veins located between the vena hepatica media (HM) and vena hepatica dextra (HD) varied widely among specimens and were irregular, including the vena hepatica dorso-lateralis sinistra (Hds), vena hepatica dorso-lateralis dextra (Hdd), vena hepatica lobi caudati (Hlc), venae hepaticae processus caudati (Hpc), venae hepaticae processus papillaris (Hpp), and the hepatic vein to the dorsal intermediate part, which directly or indirectly drained into the vena cava caudalis. The courses of the bovine hepatic veins were markedly diverse, and anastomoses between vena hepatica sinistra (HS) and Hds were observed in about a half of the livers. The portal vein entered the liver as VPC slightly above the centre of the right lobe on the visceral surface. The intermediate or transverse part [pars transversa trunci sinistri (PTS)] of truncus sinister (TS), which extends from the entry of the portal vein into the left lobe of the liver, was slightly arched downward [pars umbilicalis trunci sinistri (PUS)]. The portal vein further arched from the distal end of TS to the umbilical vein and ran towards the inter-lobar incision between the left lobe and quadrate lobe. Based on these branches, hepatic segments were determined as 13 or 14 areas. A total of 15 bile ducts were derived from various lobes. The hepatic duct was about 2.6–6 cm long from the confluence of the right and left hepatic ducts to the division of the cystic duct and the common hepatic duct.

    Testicular Dynamics in Syrian Hamsters Exposed to Both Short Photoperiod and Low Ambient Temperature (2005)

    Notes: The object of this study was to determine the details of morphological dynamics of spermatogenesis in Syrian hamsters exposed to both short photoperiod and low ambient temperature. Eight-week-old male hamsters, kept in a long photoperiod (14 h L, 10 h D), were transferred to a short photoperiod (6 h L, 18 h D) and kept there for 13 weeks to induce testicular regression. Some hamsters were then transferred from the room at 23°C to that at 5°C (5°C group). Remaining hamsters were continuously kept at 23°C (23°C group). Thereafter, the morphology was examined. As a result, it took only 8 weeks until spermatogenesis recovered in the 23°C group. However, it was not until 20 weeks that spermatogenesis was recognized in the 5°C group. As the regulation of seasonal testicular activity is characterized by coordinated shifts in the relationships among mitosis, meiosis, and apoptosis, the changes in the proliferative and apoptotic activities were examined. Although no significant difference in proliferative activity of spermatogonia between the 5°C and the 23°C groups was confirmed, a notable increase in the rate of apoptosis was observed in the 5°C group. Furthermore, this increase was more salient during the hibernation period. These findings suggest that both cold ambient temperature and hibernation caused the delay of testicular recrudescence and this delay arose from the increase of apoptotic activity but not the change in proliferative activity in spermatogonia in the 5°C group.

    Negative phototropism in the piloboloid mutants of Phycomyces blakesleeanus Bgff. (1984)

    Notes: Abstract The sporangiophore (spph) of a piloboloid mutant, genotype pil, of Phycomyces ceases elongation and expands radially in the growth zone shortly after reaching the developmental stage IV b. The pil spph is always negatively phototropic to unilateral visible light when its diameter exceeds 210 μm. Photoinduction of spph initiation, light-growth response, threshold of light energy fluence rate for the negative phototropism, avoidance and gravitropism in the pil mutant are all normal. In liquid paraffin, the pil spph shows negative phototropism as does the wild-type spph. Genetic analyses indicate that the negative phototropism of the pil mutant is governed by the phenotypic characteristics of pil but not by specific gene(s) responsible for negative phototropism. These facts imply that the reverse phototropism of the pil mutant results from a loss of the convergent lens effect of the cell because of the increase in cell diameter.

    Further observations on the morphogenesis of human rotavirus in MA 104 cells (1984)

    Notes: Summary Human rotavirus “KUN” strain was cultivated in a fetal rhesus monkey kidney cell line, MA 104 cells. Four types of virus particles in cells infected with KUN strain were clearly identified: nucleoid cores, single-shelled particles, double-shelled particles, and membrane band, “enveloped” particles. “Enveloped” particles were found only in the thin sections of infected cells. When first visible, the virus precursors appeared at the ribosome free membrane of rough endoplasmic reticulum (RER), increasing in size while simultaneously being coated with nucleocapsid, inner shell. Single-shelled particles were also synthesized within bundles of filaments of viroplasm in the cytoplasma. During subsequent virus maturation two types of “budding” processes were observed. Double-shelled particles arising at the RER membrane entered the cisternae of the RER through an exocytosis-like process. In contrast, the “enveloped” particles developed in the cisternae by being completely enclosed with RER membrane, and later during cytolysis released the single-shelled particles. These “enveloped” virus particles appeared to be the result of inefficient virus maturation at the last stage of outer capsid formation.
