Abstract
The genetic instability of an intertribal hybrid cell line, Duboisia hopwoodii + Nicotiana tabacum, obtained by mechanical isolation of a single hybrid cell was studied. Ten subclones of calli derived from this hybrid cell line were cultured for 3 years, and their genetic makeup clarified as to nuclear DNA content, chromosome constitution, and peroxidase isozymes. Nuclear DNA content differed in each subclone. In most subclones, mean DNA content was lower than the mean DNA content in the original hybrid cell line determined 1 year after fusion. This decrease in DNA content is partly attributable to the elimination of tobacco chromosomes that occurred in all subclones. The extent to which tobacco chromosomes were eliminated varied among the subclones - evidence that chromosome elimination occurred slowly. Peroxidase isozyme analysis indicated the loss of a tobacco-specific isozyme, thus confirming results obtained by chromosome analysis. Shoots regenerated from two hybrid subclones after 2 years were also heterogeneous in morphology and nuclear DNA content.

Abstract
This report describes a case of metrizamide encephalopathy with persistent disturbance of consciousness and extrapyramidal symptoms. These two conditions have rarely been reported among the various adverse effects of metrizamide. An 11-year-old girl had been in almost good health until she was ten years old, at which time she received a ventriculo-peritoneal shunt operation, suffering from hydrocephalus of unknown etiology. At the age of eleven, she was admitted to our hospital due to hydrocephalus recurrence. She was examined by metrizamide shunt-gram (1200 mg iodide/4 ml). On the next day, she became drowsy. The CT scan disclosed the periventricular penetration of metrizamide into the medial part of the thalamus and the caudate nucleus. Thirteen days later, disturbance of consciousness continued, and extrapyramidal symptoms, that is, rigo-spasticity and postural tremor, were observed. Oral administration of L-threo-DOPS, the direct precursor of noradrenaline, was effective against the persistent disturbance of consciousness and L-DOPA was effective against the extrapyramidal symptoms. She soon recovered almost to normal and no neurological deficit remained. We thus conclude that the CT scan findings and effects of L-threo-DOPS and L-DOPA suggest that metrizamide encephalopathy in this case were respectively due to its periventricular penetration into the medial part of the thalamus and the caudate nucleus, and the resultant deficiency of the ascending noradrenergic reticular activating system and the nigrostriatal dopaminergic system.

Abstract
1. Troponin T (TNT) expressed in various vertebrate skeletal and ascidian smooth muscles was examined by two-dimensional electrophoresis in combination with immunoblotting. 2. A monoclonal anti-TNT antibody, NT-302, exhibited binding ability to various TNT variants in the vertebrate and protochordate animals. 3. TNT isoform pattern differed among the animals, but the existence of multiple TNT isoforms in a single muscle tissue was the general feature of all the animals examined.

Abstract
We examined the efficacy of a new commercial assay procedure (SCC RIABEAD) for estimation of squamous cell carcinoma related antigen (SCC). Intraassay and interassay variance were 4.0-14.6% and 4.6-17.0% respectively. Recovery and dilution tests gave satisfactory results. The normal range was under the level of 1.63 ng/ml. The patients with uterine cervical cancer or squamous cell carcinoma of the lung showed high positive rates. The values of SCC measured by SCC RIABEAD were well-correlated to those by SCC RIAKIT. However, SCC RIABEAD showed lower values in low SCC level and higher values in high SCC level than SCC RIAKIT.

Abstract
Troponin T (TNT) expressed in the developing chicken cardiac muscle was examined by immunoblotting combined with two-dimensional electrophoresis (2-D PAGE) and peptide mapping. When the whole lysate of the neonatal heart was examined by 2-D PAGE, two TNT variants were detected on the gel by monoclonal antibody to TNT. Expression of the two variants was developmentally regulated: one isoform (type I) was expressed from embryonic through neonatal stages, and the other (type II) from the late embryonic stage through adulthood during cardiac muscle development. The type-I isoform, but not type-II isoform, was also expressed transiently in chicken skeletal muscle at embryonic stages. As judged from the peptide maps, the two isoforms differed in the N-terminal region but not in the C-terminal region.

Abstract
The types of troponin-T (TNT) expressed in neonatal chicken breast muscle were examined by two-dimensional gel electrophoresis (2-D PAGE), immunoblotting, and peptide mapping. When troponin from neonatal chicken breast muscle or whole lysate of the muscle was displayed on 2-D PAGE, multiple spots were observed in the TNT region on the gel. They differed slightly from those in adult breast- and leg-type TNT, but were positively stained with the antibody specific for TN-T. These results indicate that multiple spots observed in the TNT region are all TNT isoforms. The TNT isoforms in the neonatal breast muscle were classified into two groups, based on size. Each group contained about five variants. The first group with a larger size was in the molecular weight range of adult breast TNT, while the smaller-sized second group was in the molecular weight range of adult leg TNT. Overall peptide map patterns of variants in the first group and also that of adult breast TNT resembled each other, whereas those of variants in the second group were similar to that of adult leg TNT. The TNT of adult breast-type appeared at about 2- to 3-weeks posthatch, and thereafter became a major TNT isoform.
