Abstract
We investigated the immunoreactivity of the retinoblastoma protein in eight retinoblastoma tumors of different stages of differentiation. All undifferentiated tumor cells failed to show immunoreactivity. In one patient, who had a family history of retinoblastoma and had been treated by radiation, the tumor had a large area of undifferentiated cells and small independent retinocytomas. The tumor cells in the retinocytoma and the cone cells in the adjacent retina, but not the undifferentiated tumor cells, showed positive staining with two anti-Rb antibodies. The immunoreactivity may be related to radiation or differentiation of retinoblastoma and cone cells.

Abstract
7 chemicals commonly found at the industrial waste sites were tested with the Tradescantia-Micronucleus (Trad-MCN) assay to evaluate their clastogenic potential. Chemicals selected from the US EPA Superfund Priority 1 list were: aldrin, arsenic trioxide, 1,2-benz[a, h]anthracene, dieldrin, heptachlor, lead tetraacetate and tetrachloroethylene. Results of repeated tests for clastogenicity yielded the minimum effective dose (MED) for clastogenicity of 0.44 ppm for lead tetraacetate, 1.88 ppm for heptaclor, 3.81 ppm for dieldrin and arsenic trioxide and 1,2-benz[a, h]anthracene yielded positive responses at the MED of 3.96 ppm and 12.50 ppm respectively. Aldrin and tetrachloroethylene were considered to be immiscible with water, and the tests yielded negative responses. Tetrachloroethylene in gaseous state was also used to treat the flower buds. Results of tetrachloroethylene vapor phase treatment yielded a positive response at the MED of 30 ppm/min after a 2-h exposure. 5 chemicals determined to be clastogens by this test were ranked according to their MED in the descending order of potency as follows: lead tetraacetate, heptachlor, dieldrin, arsenic trioxide and 1,2-benz[a, h]anthracene. Results of this study indicate that the Trad-MCN bioassay could be effectively utilized for assessing the potential clastogenicity of the chemicals commonly found at the industrial hazardous waste sites.

Abstract
The authors studied the refractive errors and axial lengths on thirty patients. A retrospective analysis suggests some degree of monocular vision deprivation early in life. Axial myopia was found in most of the cases, indicating that emmetropization is a vision-dependent phenomenon. But, some exceptions were found, supporting the concept that multiple factors are involved in the pathogenesis of myopia.

Abstract
Relationships between leucine-enkephalin fibers and cholinergic neurons in the rat sacral intermediolateral nucleus were examined by light and electron microscopy using double-immunostaining method. Cholinergic neurons in the sacral intermediolateral nucleus were labeled by a rat-mouse monoclonal antibody to choline acetyltransferase and stained bluish green with 5-bromo-4-chloro-3-indolyl-beta-D- galactoside reaction products using beta-galactosidase as a marker. On the same sections, leucine-enkephalin fibers were labeled by a rabbit polyclonal antiserum to leucine-enkephalin and stained brown by diaminobenzidine reaction products using peroxidase as a marker. After embedding in Epon, the sections were examined in light and electron microscopes. In the light microscope, choline acetyltransferase-like immunoreactive cells were seen in the sacral intermediolateral nucleus. In the same region, leucine-enkephalin-like immunoreactive cells. In the electron microscope, 5-bromo-4-chloro-3-indolyl-beta-D-galactoside reaction products were in the form of coarse electron dense deposits in the choline acetyltransferase-like immunoreactive structures and could be distinguished from the much finer grained diaminobenzidine reaction products. Choline acetyltransferase-like immunoreactive neurons received synaptic inputs from leucine-enkephalin fibers-like immunoreactive terminals. These findings suggest that leucine-enkephalin fibers may affect the activity of cholinergic parasympathetic preganglionic neurons.

Abstract
Relationships between adrenergic fibers and cholinergic neurons were examined in the rat sacral intermediolateral nucleus using a double-immunostaining method at light and electron microscopic levels. Adrenergic fibers were immunohistochemically stained brown by peroxidase reaction, and cholinergic neurons in the same sections were stained bluish green by beta-galactosidase reaction. In the light microscope, many cholinergic neurons were seen in the intermediolateral nucleus and some of them were surrounded by adrenergic fibers. In the electron microscope, adrenergic fibers made synapses with the cholinergic neurons in the intermediolateral nucleus. These results suggest that adrenergic fibers directly influence the activity of the sacral parasympathetic preganglionic neurons.

Abstract
Effects of histidine or methionine imbalance and dietary levels (3-50%) of casein on food intake and preference of young, adult, and diabetic (2.5 month old) rats were examined. Depressions in food intake and growth caused by ingestion of the imbalanced diet were greatest in young rats and least or absent in diabetic rats. Alloxan diabetes induced hyperphagia and elevated concentrations of plasma branched-chain amino acids and decreased concentrations of tryptophan and tyrosine. The diabetic rats fed the imbalanced diet for 9 days had a higher concentration of the limiting amino acid in the plasma than the adult normal rats fed the same diet. The diabetic rats preferred the imbalanced diet over a protein-free diet when they were fed these diets concurrently. Ingestion of the imbalanced diet by normal rats caused greater changes in plasma and brain amino acid patterns than did the protein-free diet. Unlike the diabetic rats, the normal rats, especially the young rats, strongly preferred the protein-free diet over the imbalanced diet. The normal rats also preferred a 10% casein diet supplemented with L-methionine over a low or high casein diet. It seemed that young rats were able to select a protein diet that supported maximal growth when proportions of dietary amino acids were balanced. It also seemed that the susceptibility of the rats to amino acid imbalance varied directly with the status of overall protein synthesis of the animals.
