Abstract
Studies were conducted on the evolution of hepatitis B virus (HBV) surface and core antigens (HBsAg and HBcAg) in the tumors of both primary and recurrent hepatocellular carcinoma (HCC) in 27 HBsAg carriers; these were followed for up to 8 years after the resection of the primary tumor. Twenty-seven primary and 34 recurrent tumors were included. HBV antigens were detected in the tumor of the primary HCC in ten cases (37%): six (22.2%) had both antigens (Group I) and four (14.8%) had HBsAg alone (Group II). The remaining 17 cases were negative for both antigens (Group III). Intrahepatic tumor recurrence occurred in 17 cases; both HBcAg and HBsAg were found in the recurrent HCC in four of five HBcAg-positive cases (Group I). In contrast, HBcAg was detected in none of the other 12 cases (Group II, 0 of one; Group III, 0 of 11), and HBsAg in only one (Group II, 0 of one; Group III, one of 11), P less than 0.03 and P less than 0.02, respectively. Groups I, II, and III had extrahepatic recurrence in two, four, and seven cases, respectively. HBcAg was detected in none, while HBsAg was found in only one case (7.7%). The frequent detection of both antigens in the primary HCC and even in the intrahepatic recurrences suggests that HBV replication in HCC may occur more commonly than previously perceived, especially in the small HCC. Failure to detect HBV antigens in the extrahepatic recurrences suggests that the switch-off of the viral gene expression, particularly the core gene, may be an event related to the extrahepatic growth of HCC. HBV antigen expression in HCC is associated with more evident lymphocyte infiltration; this local host immune response may in turn result in a negative selection and expansion of the antigen-negative HCC cell clones. This suggestion is in accord with the fact that HBV antigens, particularly HBcAg, are rarely detected in advanced HCC.

Abstract
Naturally occurring regulatory variation is a source of genetic variability that is well documented but poorly understood. Two members of the Hawaiian picture-winged Drosophila, D. affinidisjuncta and D. hawaiiensis, display markedly different levels of alcohol dehydrogenase (alcohol: NAD+ oxidoreductase, EC 1.1.1.1) in the larval midgut and Malpighian tubules. To analyze the regulation of the alcohol dehydrogenase genes from these two species, their homologous alcohol dehydrogenase genes were cloned and introduced, via P element-mediated transformation, into the germ line of Drosophila melanogaster. Histochemical and electrophoretic analyses of larval transformants demonstrate that major differences in the tissue-specific levels of alcohol dehydrogenase production are characteristic of the alcohol dehydrogenase genes themselves. While these results do not directly address possible species-specific differences in the tissue distribution of trans-acting regulatory components, they indicate that demonstrable differences in cis-dominant regulatory information are sufficient to account for the observed regulatory variation.

Abstract
To elucidate the biologic significance of hepatocyte HBsAg, its expression patterns were correlated with virus replication and liver pathology in 578 liver biopsies taken from chronic HBsAg carriers aged 1 to 80 years. Five major patterns of hepatocyte HBsAg were identified: homogeneous [intense and discrete, (Pattern A), faint and discrete, (Pattern B) and faint and grouped (Pattern C)]; globular or spotty (Pattern D), and marginal (Pattern E). Pattern A was always associated with viremia and also very frequently with membrane HBsAg expression, but rarely with active liver disease. It occurred most commonly in HBeAg-positive carrier children and young adults, reflecting an early immune tolerance phase with active virus replication. Pattern B was also usually associated with viremia, but very commonly associated with active disease (70%), reflecting active virus replication with enhanced immune response. Pattern E (marginal HBsAg), which was always in group distribution resembling a clonal expansion, predominated the HBeAg-negative phase and was associated with absence of viremia and occurred mostly in older adults with inactive bipolar disease spectrum (normal liver/mild disease or cirrhosis/hepatocellular carcinoma); this reflects a late phase of inactive virus replication or integration. Patterns C and D did not correlate well with viremia, but also tended to have inactive diseases as did Pattern E. These findings suggest that hepatocyte HBsAg expression is closely related to the natural course of chronic hepatitis B virus infection.

Abstract
Diacetyl nadolol, a prodrug of nadolol and a beta-blocker, has corneal permeability approximately 20 times higher than that of its parent compound due to its higher lipophilicity. Hydrolysis studies were conducted for diacetyl nadolol at various elevated temperatures and pH values to provide stability information for its ophthalmic preparations. The apparent rate constants for diacetyl nadolol hydrolysis to acetyl nadolols and nadolol were determined. Within the neutral pH range (6.8 to 8.2), the hydrolysis of diacetyl nadolol may be proposed as specific base catalysis. Various constants for diacetyl nadolol hydrolysis to acetyl nadolols and acetyl nadolols to nadolol were respectively listed as following: activation energy, 9.78 and 11.39 kcal/mol; entropy at 25 degrees C, -9.78 and -5.86 cal/mol.deg; second-order rate constant at 75 degrees C, 3.47 X 10(4) and 2.22 X 10(4) M-1h-1. According to these kinetic constants, a diacetyl nadolol aqueous solution with pH 6.5 may be prepared as an antiglaucoma agent. The shelf-life was estimated to be only 43 d at room temperature (25 degrees C). However, when the storage temperature is lowered to 5 degrees C, the shelf-life can be extended to greater than 2 years.

Abstract
Proplast was implanted in 15 cases of orbital reconstruction. Seven cases were orbital floor fractures, four cases were phthisical enophthalmos, and four cases were anophthalmic enophthalmos. In orbital floor fracture cases, thin (2-mm) Proplast was placed onto the fractured orbital floor after the incarcerated orbital tissue was released. To correct the enophthalmic socket, Proplast was shaped into small pieces (10 x 5 x 2 mm), then inserted into the subperiosteal space from all directions to fill up the orbital cavity. The results of these 15 cases were satisfactory. The average follow-up period is 13 months. The increased orbital volume seems less than the volume of the implanted Proplast; therefore, we suggest an 80-90% overcorrection rate in accordance with the computer measurements. In sum, Proplast serves as a very good material for orbital floor reconstruction and volume replacement.

Abstract
The essential fatty acid deficient (EFAD) chicken was evaluated as a model for cystic fibrosis (CF). Three semipurified diets--(I) 1% hydrogenated coconut oil (HCO), (II) 10% soybean oil + 1% HCO, and (III) 11% HCO--were fed to chickens from hatching to 5, 8, or 11 wk. Groups I and III exhibited poor weight gain and abnormal serum fatty acid patterns characteristic of EFAD. Production of prostaglandin F2 alpha, thromboxane B2, 6-keto-prostaglandin F1 alpha, and prostaglandin E in lung was significantly reduced at 5, 8, and 11 wk in both EFAD groups. Histopathologic examination revealed increased peribronchiolitis in group I compared with II. Incidence of pulmonary lesions in group III was intermediate. These data support the theory that essential fatty acids are necessary to maintain proper lung function. In this respect, the chicken is a good model for studying the relationship between EFAD and pulmonary disease in CF patients.

Abstract
Bradycardia was produced by electrical stimulation and injection of glutamate (200 nl, 1 M) to the regions in and around the extremely caudal parts of the inferior olivary nucleus (ION) in chloralose-urethane anesthetized cats. Either medullary transection at 4 mm rostral to the obex, spinal transection at C2-3 or both transections together did not abolish the ION-induced bradycardia. Bradycardia induced by stimulating one ION was slightly reduced and completely abolished by unilateral and bilateral vagotomies, respectively. The ION-evoked bradycardia was also slightly reduced by a raphe lesion. This lesion together with unilateral vagotomy abolished only the bradycardia induced from the ION on the vagotomized side. In 28 left vagotomized cats, the left ION-induced bradycardia was subjected to the effects of destroying the right ION, dorsal motor/solitary nucleus (DM/SN) and ambiguous nucleus (AN). The bradycardia was completely abolished by ION lesion (7/7), greatly reduced (7/13) or completely abolished (6/13) by DM/SN lesion, and slightly increased (5/8) or decreased (3/8) by AN lesion. We concluded that cells and/or fibers in and around the ION may project fibers to the ipsilateral DM/SN and through the raphe nucleus to the contralateral ION which may send fibers to the other DM/SN.

Abstract
Six different monoclonal antibodies (IgG1 and IgG2a) were obtained after fusions of X63-Ag8-6.5.3 myeloma cells with spleen cells from BALB/c mice immunized with bovine insulin. Definition of binding determinants was attempted by competitive binding studies with insulins, proinsulins and modified insulins from various species. The monoclonal antibodies OXI-001 and OXI-004 were inferred to react with a region including residue A10, OXI-002 with an antigenic determinant in the B26-30 region, OXI-005 with a region including B30 and OXI-006 with a tertiary structure near the N-terminus of the B chain, possibly including B3 and A10. The equilibrium binding constants for these antibodies were calculated by three different methods (Scatchard, Langmuir and non-linear regression) and were found to be in the range of 2 X 10(7)-8 X 10(9), with good agreement between the different methods of calculation. As expected for a given monoclonal antibody, the heterogeneity index was close to 1.0, as calculated from Sip's logarithmic transformation of the binding equation. These parameters were compared to those of a mixture of the six different monoclonal antibodies and those of a conventional hyperimmune anti-insulin serum (guinea-pig). The half-dissociation times (t1/2) of complexes of antibody and bovine insulin ranged from 35 min to 38 h.

Abstract
The glycoprotein hormone hCG and its free alpha-subunit are secreted by the clonal choriocarcinoma cell line JEG-3. Free hCG alpha has a larger apparent mol wt (22,000-24,000) than the combined hCG alpha (18,000-19,000) obtained by dissociation of the hCG secreted by these cells. Techniques developed for the specific isolation and purification of the free and combined hCG alpha forms and for the preparation of glycopeptides from these subunits have permitted detection of the incorporation of D-[3H]glucosamine [( 3H]GlcN) and L-[3H]fucose into both alpha-subunit forms. Relative to their [35S]methionine content, 2.3-fold more [3H]GlcN and 6-fold more L-[3H]fucose were incorporated into free hCG alpha than into combined hCG alpha. Analyses of [3H]GlcN glycopeptides prepared from free and combined hCG alpha indicate that the 22,000- to 24,000-dalton subunit form contained more [3H]GlcN and 27% more of the GlcN metabolite N-acetylneuraminic acid than the 18,000- to 19,000-dalton hCG alpha-subunit, than both hCG alpha forms contained two major N-linked oligosaccharide chains differing primarily in their NeuAc content, and that most of the [3H]GlcN was incorporated as GlcN or metabolites of GlcN other than N-acetylneuraminic acid. These studies provide direct chemical evidence of a higher content of carbohydrate in the larger free alpha-subunit form.

Abstract
A widely used food additive erythrosine B, which has been implicated in minimal brain dysfunction in children was examined for its ability to increase membrane permeability to calcium ions. Planar phospholipid bilayer membranes become permeable to calcium, potassium and chloride ions and when erythrosine B is added to the aqueous phase at concentrations which were used by others to demonstrate effects on neuromuscular preparations. The observed increase in permeability to Ca2+ was of sufficient magnitude that equivalent effects on cells would seriously tax the systems which maintain low cytoplasmic Ca2+ levels. The permeability increase in the lipid bilayer membrane is time dependent and increases with erythrosine B concentration raised to a high power (4 to 7). This indicates that the permeability pathway is generated by the cooperative action of a number of erythrosine molecules. This permeability increases dramatically with increasing transmembrane voltage indicating that cells or organelles bearing potentials across their membranes should be particularly sensitive to the dye. We propose that the neurological effects of erythrosine stem from the increased Ca2+ permeability.

Abstract
The synthesis and antirhinovirus activity of syn and anti isomers of 6-[[(hydroxyimino)phenyl]methyl]-1-[(1-methylethyl)sulfonyl]-1H-benzimidazol-2-amine (4 and 5) are reported. The structural assignments of 4 and 5 are based upon 13C NMR spectra of both isomers and also X-ray analysis of 5. The anti-isomer 5 was more potent than the syn-isomer 4 when compared as an inhibitor of rhinovirus multiplication in vitro. Both isomers inhibited multiplication of 15 different serotypes of rhinovirus.

Abstract
The characterization of a lithium supersonic nozzle beam has been made using spectroscopic techniques. It is found that at a stagnation pressure of 5.3 kPa (40 Torr) and a nozzle throat diameter of 0.4 mm the ground state vibrational population of Li(2) can be described by a Boltzmann distribution with T(v)= (195+/-30) K. The rotational temperature is found to be T(r)= (70+/-20) K by band shape analysis. Measurements by quadrupole mass spectrometer indicate that approximately 10-mol. % Li(2) dimers are present far downstream for an oven body temperature of 1370 K in the supersonic nozzle expansion. This measured mole fraction is in agreement with the existing dimerization theory.
