Abstract
Venom toxins were isolated from Formosan cobra (Naja naja atra) by cation-exchange chromatography. Most toxin components could be obtained in relatively pure forms by single-step ion-exchange chromatography whereas an extra step of gel permeation was needed for the separation of phospholipase A2 (PLA2) from the major neurotoxic component, i.e. cobrotoxin. The newer near-IR FT-Raman analytical method has been applied to the characterization of PLA2 in their lyophilized forms. Structural analysis of PLA2 and correlation of Raman spectroscopic data with amino acid compositions were made. The results indicate that phospholipase A2 showed the Raman peak at 1659 cm-1 which is characteristic of the alpha-helical structure in this enzyme. It is also found that the relative Raman signal intensities of Tyr, Phe, Trp and Met residues in purified toxins correlate very well with the structural data obtained from amino acid analysis. The application of near-IR FT-Raman techniques in the detection of the microenvironments of the aromatic amino acids such as Tyr and Trp in the native toxins may prove useful in the investigation of the functional properties of various venom toxins.

Abstract
A new transient expression system has been developed to investigate the function of anion exchangers in vivo. Human 293 cells were cotransfected with AE2 or AE3 cDNA together with a plasmid encoding a cell surface marker protein. Staining of the cells with antibody directed against a cell surface epitope present in the marker protein permitted the detection of cells expressing functional anion exchangers. Intracellular pH (pHi) recording in individual transfectants loaded with the fluorescent pHi indicator, 2',7'-bis(carboxyethyl)-5,6-carboxyfluorescein, was used to determine the flux of HCO3- as a measure of Cl-/HCO3- exchange activity. Cells expressing either anion exchanger displayed significantly enhanced Cl-/HCO3- exchange activity compared with controls expressing only the marker. Transfection with either anion exchanger or with control plasmid resulted in altered intrinsic buffering capacity profiles compared with untransfected controls. Expression of either AE2 or AE3 did not result in changes in resting pHi. The activities of both AE2 and AE3 were stimulated at alkaline pHi, suggesting that an internal protonation site in AE2 and AE3 may regulate their activities. Both exchangers were inhibited reversibly and irreversibly by the anion 4,4'-diisothiocyanostilbene-2,2'-disulfonate with IC50 values of 142 and 0.43 microM for AE2 and AE3, respectively. These data indicate that structural differences in these highly conserved anion exchangers give rise to differences in affinities at the external anion binding site.

Abstract
A laser scanning micro-probe has been used to elicit resonance Raman signals from frozen sections of the lens of the deep-sea hatchetfish, Argyropelecus affinis. The signals demonstrate with certainty the presence of a carotenoid and its distribution in the lens. The carotenoid exhibits characteristic resonance Raman vibrational modes at 1551 cm-1 (C = C stretch, v1), 1147 cm-1 (C-C stretch with C-H bend, v2), 2285 cm-1 (2v2) and 2681 cm-1 (v1 + v2), upon excitation at 441.6 nm. Unlike glycogen in the nucleus of dove lens, the carotenoid in the lens of A. affinis occurs at a higher concentration in the cortex, although its presence in the nucleus is established. A study of lenses of varying age showed that carotenoid incorporation is accelerated as the fish grows older and hence its concentration is highest in the cortex. Because of the extremely low concentration of the carotenoid in the nucleus, it was detectable only by the very sensitive resonance Raman technique.

Abstract
Coherence scanning microscopy is a new technique in high resolution imaging. It shares many of the features of confocal microscopy but uses coherence effects to enhance the lateral and longitudinal resolution rather than physical apertures. This approach has two significant implications for profilometry: the longitudinal resolution is decoupled from the lateral resolution, and interference effects can be used to further enhance the longitudinal resolution. We detail the features of coherence scanning profilometry and give some examples.

Abstract
We have isolated rat brain cDNA clones encoding AE2, a homologue of the erythrocyte anion exchanger, band 3 (AE1). Immunocytochemistry and in situ hybridization reveal that, in brain, AE2 expression is restricted to the basolateral membrane of the choroid plexus epithelium. Expression of a full-length mouse AE2 cDNA in COS-7 cells resulted in chloride- and bicarbonate-dependent alterations in intracellular pH, demonstrating that AE2 is a Cl/HCO3 exchanger. Cation replacement studies indicate that AE2-mediated exchange is independent of extracellular sodium. COS-7 cells expressing a mutant rat AE2 cDNA clone that lacks the cytoplasmic NH2-terminal 660 amino acids exhibit identical responses to cation and anion substitution. These results indicate that this domain does not play a significant role in either correct insertion of the transporter into the plasma membrane or anion exchange.

Abstract
A full length cDNA encoding human pro-alpha 2(V) collagen was constructed. Partial sequencing of the cDNA and primer extension analysis of mRNA from fibroblasts found that pro-alpha 2(V) mRNA differs from the mRNAs of other fibrillar collagens in the increased length of its 5'-untranslated region. The pro-alpha 2(V) cDNA was placed downstream of the human cytomegalovirus immediate early promoter/regulatory sequences for expression studies in cultured Chinese hamster lung cells. These cells have been shown previously to synthesize large quantities of pro-alpha 1(V) homotrimers as their only collagenous product. Transfection resulted in a number of clonal cell lines that express human alpha 2(V) RNA at levels comparable to, and in some cases greater than, levels found in normal human skin fibroblasts. Pro-alpha 2(V) chains produced in the majority of clonal lines were of sufficient quantity to complex all available endogenous pro-alpha 1(V) chains. Chimeric heterotrimers, composed of hamster alpha 1(V) and human alpha 2(V) chains in a 2:1 ratio, were stable to pepsin digestion and were found predominantly associated with the cell layer. Surprisingly, pro-alpha 2(V) chains, in excess to pro-alpha 1(V) chains, were found in the extracellular matrix and, in much greater abundance, in media. These chains were pepsin sensitive, indicating that pro-alpha 2(V) chains can be secreted as nonstable homotrimers or as free chains.

Abstract
We have isolated AE3, a novel gene expressed primarily in brain neurons and in heart. The predicted AE3 polypeptide shares a high degree of identity with the anion exchange and cytoskeletal binding domains of the erythrocyte band 3 protein. Expression of AE3 cDNA in COS cells leads to chronic cytoplasmic acidification and to chloride- and bicarbonate-dependent changes in intracellular pH, confirming that this gene product is an anion exchanger. Characterization of an AE3 mutant lacking the NH2-terminal 645 amino acids demonstrates that the COOH-terminal half of the polypeptide is both necessary and sufficient for correct insertion into the plasma membrane and for anion exchange activity. The NH2-terminal domain may play a role in regulating the activity of the exchanger and may be involved in the structural organization of the cytoskeleton in neurons.

Abstract
Homozygous lymphoblastoid cell lines representing Dw subtypes of the DR2 serotype were studied for structural polymorphism at DR beta. These subtypes included Dw2, Dw12, and non-Dw2/non-Dw12. Analysis by two-dimensional gel electrophoresis showed that two DR beta genes were expressed in each cell line studied. One of these expressed genes encoded a protein that was nonpolymorphic on two-dimensional gel electrophoresis among all subtypes. The second expressed DR beta gene was polymorphic and migrated to a position on two-dimensional gels dependent on the subtype of the cell line. cDNA sequence analysis of the DR beta genes revealed a DR beta gene identical between the Dw2 and Dw12 subtypes, which correlates with the nonpolymorphic spot on two-dimensional gels. A second gene was sequenced that exhibited variability between the Dw2 and Dw12 subtypes. This variability takes the form of clustered point mutations in the first domain of the molecules. The alleles from the DR beta genes of a non-Dw2/non-Dw12 cell line, AZH, were unusual in sequence. In contrast to other DR beta alleles, the AZH genes may have been generated by a double recombinational event between two DR beta loci from a DR2 parent. The DR2 serotype may also constitute a supertypic "family," with one DR beta gene relatively nonpolymorphic, and one that varies with Dw subtype.

Abstract
Active laser diode interferometers in which the interference signal is fed back to the diode current are investigated for Twyman-Green and self-coupling interferometers. The Twyman-Green interferometer is stabilized with a stabilization factor of more than 100. By using the feedback signal of either type of interferometer, displacement is measured in a linear scale over a dynamic range of 8-9,microm with a precision of 10-60 nm. The feedback signal vs displacement shows hysteresis and multistable behavior, in accordance with theoretical results.

Abstract
Homozygous lymphoblastoid cell lines representing various Dw subtypes of DR2 were examined for polymorphism at the DQ beta locus by molecular and cellular techniques. The subtypes studied included Dw2, Dw12, and a group heterogenous by cellular typing that we shall refer to as non-Dw2/non-Dw12. Restriction fragment length polymorphism analysis of cell lines representing these subtypes revealed DQ beta-specific patterns consistent with cellular typing. Two-dimensional gel electrophoresis of DQ molecules from representative cell lines revealed a structural polymorphism of DQ beta among the three subtypes. The DQ beta chain migrated to a position that was unique to each subtype and was consistent among various representative cell lines of each subtype. Nucleotide sequence analysis of cDNA clones of DQ beta from Dw2, Dw12, and non-Dw2/non-Dw12 lines confirmed that the variability resided at the genetic level. Variability was found in the form of numerous scattered nucleotide substitutions throughout the first domain of these alleles. The DQ beta gene of the non-Dw2/non-Dw12 cell line AZH was further found to be almost identical with the DQ beta gene of a DR1 line (Bell et al. 1985b), implicating a common evolutionary origin of these alleles. The only difference between these two sequences was due to an apparent gene conversion event at amino acid 57. T-cell cloning experiments resulted in the derivation of Epstein-Barr virus-specific, DQw1-restricted clones that proliferated against only those cell lines that exhibited the DQ beta gene common to AZH and the DR1 cell line. Thus, the polymorphism among DQ beta alleles within DR2 results in subtype-specific restriction.

Abstract
The effect of exogenous phospholipids on chick kidney mitochondrial 25-hydroxyvitamin D-3 metabolism was examined. Phosphatidylserine, phosphatidylcholine and phosphatidylinositol had no effect on either the 1- or 24-hydroxylation of 25-hydroxyvitamin D-3. Phosphatidylethanolamine and cardiolipin both brought about a dose-dependent decrease in the 1-hydroxylase activity in mitochondria from vitamin D-deficient chicks but not from vitamin D-replete chicks. There were no major differences in the phospholipid composition of mitochondria from vitamin D-deficient and -replete chicks nor in the fatty acid composition of these phospholipids. Preliminary kinetic studies suggest that cardiolipin acts as a noncompetitive inhibitor of the 1-hydroxylase in mitochondria isolated from vitamin D-deficient chicks. It does not appear to exert its effect by virtue of altering the distribution of substrate or products. Investigation of the effect of fatty acid methyl esters on the hydroxylase activities suggests that it may be the fatty acid moiety of the phospholipid, rather than the phosphate moiety in the polar head group, that is involved in the phospholipid effect on the hydroxylation of 25-hydroxyvitamin D-3.

Abstract
This study proposes to test for the existence of an adaptation effect of rural-to-urban migration. The design is to divide migrants into two groups at the time of observation: one group which had migrated by that time, and another group consisting of individuals who had not yet migrated but are known to migrate later. It is presumed that if the former group had not migrated it would have had a birth path similar to the latter group. Adaptation is measured by the difference between this hypothetical birth path and the actual birth path of migrants observed after they migrate. The model is tested on Korean women and found to support the existence of an adaptation effect.

Abstract
Wrist deformities developed in ten children secondary to injury of the growth plate and premature closure of the distal radial epiphysis. Premature closure of the growth plate followed epiphyseal compression injuries or repeated forceful attempts at reduction. These injuries should not require repeated reductions in children with epiphyseal remodeling potential of more than two years if the initial reduction achieves apposition of more than 50%. Gross deformity develops if the discrepancy between radial and ulnar lengths is more than 4 mm. Ulnar shortening and correction of the radiocarpal angle, as required, constitute the surgical treatment of choice for growth deformity.

Abstract
A stuttering therapy method using two-track tape recorders of the language learning type was evaluated. Thirty-six stutterers, ages 13 to 43, were randomly assigned to one of three conditions for six months: (1) a standard therapy, (2) tape-recorder therapy, and (3) a waiting list without therapy. Using the TAT speaking task, severity ratings were obtained on each subject prior to therapy and at three-month intervals during the six months of therapy or waiting list. Both therapy groups showed significant speech improvement; die waiting list controls did not. Reasons for the therapeutic effects of the tape-recorder therapy method are discussed.
