Abstract
It has been found that the effects of opiates and opioid peptides on RVD are of two types. Compounds of the first type such as Etor, Eton, fentanyl and prodine derivatives, Met- and Leu-Enk and DADL are biphasic in nature. At lower concentrations (10(-8)-10(-5) M) they have inhibitory effects and at higher concentrations (10(-5)-10(-4) M) they are excitatory. Compounds of the second type, such as Mor, benzomorphan derivates, Cyc and SKF and the antagonist Nx have virtually no or only weakly inhibitory effects but may antagonize the inhibitory effect produced by the first group of compounds at lower concentrations. MC belongs to the second type, but it cannot antagonize the inhibitory effect of beta-End. The results are discussed in terms of multiple receptors, the high and low affinity binding sites, and the interrelationship between receptors.

Abstract
A chronic animal model is described which permits for the first time the continuous measurement of uterine artery blood flow velocity in the pregnant guinea-pig by using a miniaturized Doppler flow probe. Preliminary validation revealed that alterations in actual blood flow are directly and proportionally related to the change in the Doppler shift (r = 0.984) from 0 to 100 ml/h. The velocity signal baseline was as stable as that of systemic blood pressure. Depending upon the individual animal's flow velocity, a deviation of 2-5% from baseline was statistically significant. With experience, greater than 90% of preparations were successful and a 30-day interval was often available for study. Uterine artery flow velocity increased steadily between 45 and 55 days of gestation. Instrumentation did not result in fetal growth retardation. A reduction in flow velocity occurred during general anaesthesia using ketamine and the antianxietal xylazine. In agreement with the reports of other investigators using a different model, both hydralazine and angiotensin II increased uterine blood velocity and adrenaline reduced it.

Abstract
The nicotinic acetylcholine receptor is a multisubunit, membrane-spanning protein that contains a gated, cation-conducting channel. Our approach to the understanding of the function of this receptor in molecular terms has been to locate its functionally significant sites in the sequences of its subunits and in its three-dimensional structure. In addition, we have tried to correlate transitions in the properties of these sites with functional transitions of the receptor. On binding acetylcholine, the nicotinic acetylcholine receptor enters at least two transient states, the open state and the rapid-onset desensitized state, and, in the continued presence of agonist, finally subsides into the slow-onset desensitized state. The transitions of the receptor between these various states are susceptible to regulation by acetylcholine and its congeners acting at one type of site and by a broad class of noncompetitive inhibitors (NCIs), including local anesthetics, acting at other sites. The chain composition of the receptor is alpha 2 beta gamma delta. The two acetylcholine binding sites are on the alpha chains, and two residues contributing to these sites, Cys-192 and Cys-193, have been identified. Furthermore, these adjacent Cys residues are cross-linked by a disulfide bond. In the quaternary structure of the receptor, the chains appear to be arranged in the order alpha gamma alpha beta delta around a central channel. Both the alpha and beta chains contribute to functionally significant NCI binding sites. The addition to receptor-rich membrane from Torpedo electric tissue of agonists (but not competitive antagonists) renders these NCI sites susceptible to photolabeling by the NCI quinacrine azide (QA). Furthermore, this susceptibility is transient, arising in milliseconds and subsiding in hundreds of milliseconds. These transiently susceptible sites are protected by other NCIs against photolabeling by QA. The time-course of the susceptibility and its dependence on agonist-concentration suggest that it might be the transient, rapid-onset desensitized state of the receptor that is most susceptible to photolabeling by QA.

Abstract
The beta-adrenergic antagonist propranolol was activated through its side chain, coupled to bovine serum albumin, and injected into BALB/c mice. After fusion of the splenocytes from these immunized mice with the NS-1 myeloma cell line, two hybridomas, producing monoclonal anti-propranolol antibodies, were isolated. Clone P-49 was monospecific for propranolol, with a significant preference for the 1-stereoisomer, as compared to the d form. On the other hand, clone P-28 cross-reacted with alprenolol as well as some other beta-antagonists. Both classes of antibodies competed with A431 epidermoid carcinoma beta 2-adrenoceptors for the binding of [3H]propranolol. When ascites cells from clone P-28 were fixed with glutaraldehyde, the anti-propranolol monoclonal antibody became cell bound. These cell-bound P-28 antibodies bind propranolol and other beta-adrenergic ligands with a similar ranking order to the soluble monoclonal antibody. The cell-bound antibody displayed a 5-fold higher affinity towards 1-propranolol than the soluble monoclonal antibody. The practical implications of these findings are discussed.

Abstract
Aldehyde fixation of hybridoma cells during active production of monoclonal antibodies (MAbs) resulted in the formation of an insoluble phase because a large number of immunologically active antibody molecules were immobilized on the fixed hybridoma cells. Such MAb preparations specific to large protein molecules and small haptens were used for the development of a homogeneous immunoassay concept.

Abstract
A series of (o- and p-nitrobenzyloxycarbonyl)-5-fluorouracil derivatives were synthesized by reacting o- or p-nitrobenzyl chloroformate with 5-fluorouracil in the presence of triethylamine in DMF or Me2SO. The reductive activation of these agents was hypothesized to generate a reactive methide and 5-fluorouracil, two components that are capable of synergistic interaction through complementary inhibition. Measurement of the surviving fractions of EMT6 tumor cells treated with these agents in culture under conditions of hypoxia and aerobiosis resulted in equal cell kill regardless of the state of oxygenation. One of the synthesized agents, 3-(p-nitrobenzyloxycarbonyl)-5-fluorouracil (4), appeared to be superior to 5-fluorouracil in prolonging the survival time of mice bearing intraperitoneal implants of the P388 leukemia and Sarcoma 180.

Abstract
Thirteen phage clones containing low-copy sequences were isolated from a human DNA library and tested for their ability to detect restriction fragment length polymorphisms (RFLPs). Reported are the RFLPs revealed with each clone, all found in frequencies useful for linkage studies. Cytological data are available for five of the 13 clones, with regional assignments made for three of the markers by in situ hybridization. It is concluded that phage clones containing large unique DNA inserts detect multiple RFLPs with high efficiency. An analysis of the relative efficiency of 20 restriction enzymes for detecting single nucleotide changes is discussed by comparing the observed data to those expected on the basis of recognition and potential site frequencies, as computed from the dinucleotide distribution. Finally, in an effort to facilitate linkage studies using polymorphic DNA sequences, experiments were made with pools of probes from various sources.

Abstract
Tetanus is an infectious disease affecting the neuromuscular system. Two of its most common symptoms, trismus and dysphagia, fall within the expertise of the otolaryngologist, and may result in the patient with the disease seeking his attention initially. Since the diagnosis of tetanus is a purely clinical one and does not involve diagnostic laboratory tests, it is of paramount importance for the practicing otolaryngologist to be thoroughly familiar with the clinical presentation of the disease.

Abstract
Antisera generated against each of seven synthetic peptides corresponding to constant and variable sequences of the pilin from gonococcal strain MS11 were assayed for their ability to crossreact with intact pili from both homologous and heterologous strains. The peptides elicited roughly equal antipeptide responses but varied substantially in their ability to elicit antisera that crossreacted with intact pili. Of the antisera to peptides corresponding to regions of conserved sequence, antisera directed against residues 69-84 were the most efficient in binding pili from all strains tested in both solid-phase assays and immunoblots. Anti-69-84 also efficiently precipitated a tryptic fragment of pilin known to bind human endocervical cells. Sera against the two peptides (121-134 and 135-151) previously shown to contain strain-specific epitopes crossreacted with MS11 pili equally well, but differed in their ability to bind pili from heterologous strains. Anti-121-134 was strain-specific whereas anti-135-151 bound all pilin tested. Each of the sera was examined for its ability to inhibit bacterial adhesion to a human endometrial carcinoma cell line. Sera generated against residues 41-50 and 69-84 successfully inhibited a heterologous gonococcal strain from binding. These peptides could be important components of an effective vaccine for the prevention of gonorrhea.

Abstract
D-Arabinosyl, D-ribosyl, D-glucosyl, D-galactosyl, D-mannosyl, and L-rhamnosyl N-glycosides of p-aminobenzoic acid and their O-acetyl derivatives have been synthesized, and their ability to (a) inhibit the replication of cultured B16 melanoma cells and (b) modify the synthesis of glycosaminoglycans by these neoplastic cells have been evaluated. The most cytotoxic compound of the series was N-(p-carboxyphenyl)-2,3,4-tri-O-acetyl-D-arabinopyranosylamine (8), which produced 50% inhibition of cellular proliferation at a concentration of 4 microM; a number of other compounds were relatively cytotoxic, causing 50% inhibition of cell replication at levels of 18 to 49 microM. These effects were not due to modification of glycosaminoglycan biosynthesis, since these compounds were ineffective as inhibitors or initiators of the formation of these macromolecules.

Several of the synthesized xylosides appeared to be capable of serving as artificial initiators of glycosaminoglycan synthesis, with the most active agents causing approximately 2- to 4-fold increases in the incorporation of [35S]sulfate into the glycosaminoglycans of B16 melanoma cells excreted into the culture medium.

Abstract
The surface anionic site distribution on membranes of a monoclonal antibody-producing hybridoma cell line, and its two parental cells: normal spleen cells of immunized BALB/c mice and cells from a mouse myeloma line (NS-1), were investigated with the aid of the cationized ferritin (CF) labelling method, following glutaraldehyde/formaldehyde fixation of cells. The patch-like CF distribution on the hybridoma cells is similar to that of the NS-1 myeloma cells, but distinct from the even and continuous CF distribution of the immunized and nonimmunized normal spleen lymphocytes. The similarity in the formation of patch-like CF heaps, both on myeloma and hybrid cells is discussed in respect to the surface charge characteristic determined by cell fusion.

With the aid of a double antibody radioimmunoassay it was established that PC2-McAb recognizes an immunodeterminant associated with beta-HCG subunit, whereas, PD3-McAb recognizes an epitope present on the alpha-HCG subunit. Both monoclonal antibodies showed an affinity constant of approximately 5 X 10(10) L/M. Because of these immunological characteristics, only PC2-McAb specifically reacts with HCG and shows cross-reactivities of less than 0.1% to other related human glycopeptide hormones. On the other hand, using a hemagglutination test based on antibody induced agglutination of sheep red blood cells coated with HCG, it was shown that only PD3-McAb is capable of inducing a positive reaction, although both monoclonal antibodies have a similar binding capacity to the coated cells. The potential of these two new monoclonal reagents for the qualitative detection and quantitative determination of HCG in human biological fluids is discussed.

Abstract
The activity of inspiratory neurons in the nucleus tractus solitarius (NTS) and of expiratory neurons in the nucleus retroambigualis (RNA) was recorded during the iontophoresis of L-glutamate, bicuculline, and strychnine in chloralose-urethane-anesthetized cat. Bicuculline methoxide caused increased activity of NTS and NRA neurons during their active or burst phases. Neither bicuculline nor strychnine caused increased activity during the silent phases of NTS or NRA neurons. When neurons were driven to fire during their silent phase by L-glutamate, the application of bicuculline methoxide caused a diminution of the evoked activity. It is concluded that both inspiratory and expiratory neurons receive inhibitory inputs during both their active and silent phases. Gamma-aminobutyric acid appears to be gating both the excitatory and inhibitory information to NTS and NRA neurons. Strychnine was generally ineffective in changing the firing patterns of inspiratory and expiratory neurons suggesting a limited role of glycine, taurine, and L-alanine in the respiratory network.

Abstract
A genetically determined, polymorphic electrophoretic variant of thyroxin-binding alpha-globulin (TBG) is found in sera from populations of African and Oceania origin, although not in Caucasians nor Orientals. The TBG polymorphism is inherited in X-linked fashion, based on data from American blacks, and thus provides an X-chromosome marker with a relatively high gene frequency in this ethnic group (frequency of the slow allele, TBGs, is 11%). This slow variant should prove valuable in expanding the map of the X chromosome and in linkage studies. An additional family exhibiting X-linked TBG deficiency is also described.

Abstract
Twenty-seven subjects with a family history of Waardenburg's syndrome were examined with respect to 18 specific characteristics of the syndrome, with particular emphasis in identifying the spectrum of the phenotypic expression of affected persons. Our results indicate that patients with the syndrome may have a variety of clinical signs, and an accurate diagnosis will therefore depend on a thorough and pertinent family history and physical examination.

Abstract
The acupuncture treatment situation was beneficial to the majority of people with low back pain. This was shown by the use of short-term controls and long-term controls, although the latter were not intended in the study design. After acupuncture, there was a 51% pain reduction in the average pain score in the Immediate Treatment Group. The short-term controls, the Delayed Treatment Group, had no reduction whatsoever in their pain scores at the comparable followup period. Later, the Delayed Treatment Group bere also treated by acupuncturists, and reported 62% less pain. When these two treatment groups were compared at 40 weeks with long-term controls (Inadequate Treatment Group), the Inadequate Treatment Group still had the same pain scores, on the average, as when they enrolled in the study. Both treatment groups, on the average, had 30% lower pain scores. Furthermore, 58% of the treatment groups felt that they were definitely improved at 40 weeks, while only 11% of the Inadequate Treatment Group felt definitely improved at 40 weeks.
