Abstract
OBJECTIVE To develop a new immunobead binding test (IBT) procedure that will detect sperm antibody in cervical mucus (CM), especially in very small samples of mucus. DESIGN After the interaction of donor sperm with bromelin-dissolved CM, the motile sperm cells were separated from other cells and debris and then tested with a standard immunobead method. SETTING The CM and serum samples were obtained from a sequence of referred patients who were sent to this testing laboratory. PATIENTS There were 60 women who provided 64 samples of CM and 41 samples of blood serum. They were partners in infertile couples. INTERVENTIONS None. MAIN OUTCOME MEASURE A useful distinction was made between positive and negative results for the mucus samples by this CM-IBT procedure. The usable samples of mucus could be as little as 0.05 g (wet weight). RESULTS From the 60 women, seven mucus samples were positive; in the repeated testing, the same results were obtained with five of the six positive samples and seven of seven negative samples. CONCLUSION This method (CM-IBT) can be clinically useful for detecting sperm antibody in CM, especially because it is effective for tiny samples. In this method, the motile sperm cells are better separated from the debris after the incubation step. When the IBT was applied to the serum samples from the same women, there was no correlation between serum-IBT and CM-IBT, showing that both materials must be tested.

Abstract
The biological response modifying activities of cefodizime (CDZ), a new third-generation cephalosporin, were investigated in vitro and ex vivo. In vitro investigations using cells isolated from the blood of young healthy donors showed no stimulating activity of CDZ on peripheral blood lymphocytes, natural killer cell activity, IL-1 production by adherent mononuclear cells, PMN chemiluminescence or PMN chemotaxis. A slight but statistically insignificant increase in PMN phagocytosis and phagocytic index was observed in the same population. IL-1 production was increased in three subjects with low resting state values. In a controlled ex vivo study, 20 healthy elderly subjects selected on the basis of depressed phagocytic function were treated with CDZ 1 g i.m. b.i.d. or placebo for eight days. PMN function was determined at baseline and on the day after the last dose. In the CDZ group a significant increase in both phagocytosis and phagocytic index was found, while there were no changes in the placebo group. In conclusion, CDZ restored depressed PMN phagocytic function in a population of elderly subjects. Patients with impaired PMN function who require antibiotic treatment may benefit from this activity of CDZ.

Abstract
Internalization of CD4 molecules on human CD4-enriched T-cells was demonstrated by immunocytochemical electron microscopy. CD4+ T-cell subclones were obtained from normal human peripheral blood, followed by one-way MLC screening and co-culturing with IL-2. Fixed and non-fixed T-cell samples were indirectly immunolabeled with mouse anti-human CD4 monoclonal antibody and goat anti-mouse IgG conjugated with peroxidase. Unfixed T-cells were immunolabeled at 4 degrees C and then re-incubated for 5-45 min at 37 degrees C. The selected CD4+ T-cell subclones showed strong CD4 binding on the cell surface after IL-2 incubation. However, fresh T-cells, monocytes, bone marrow cells and CD8+ T-cells all stained negative for CD4. The distribution of CD4 molecules on the fixed cell surface showed a homogeneous pattern. Capping and internalization of CD4-antibody-peroxidase complexes from the cell surfaces were observed follow a pathway of receptor-mediated endocytosis in unfixed T cells. Endocytotic vesicles, vacuoles of diverse sizes and shapes near the cell membrane or deep in the cell center were found to contain CD4 molecules. Negatively stained Golgi saccules were observed up to 45 min after re-incubation. These results suggest that increased CD4 molecules can be induced on the surface of normal human T-cells in vitro. Internalization and accumulation of CD4 molecules occurred in CD4-enriched T-cells with IL-2 pretreatment.

Abstract
The intraperitoneal injection of anaesthetic agents is a simple and convenient method of anaesthetizing rats. However, all of the anaesthetic combinations in current use which are administered by intraperitoneal injection produce prolonged sedation, and full recovery of consciousness may take several hours. Fentanyl, a mu agonist opioid, and medetomidine, an alpha 2-adrenoceptor agonist were mixed and administered as a single intraperitoneal injection. Combinations of 300 micrograms/300 micrograms/kg and 300 micrograms/200 micrograms/kg of fentanyl/medetomidine were shown to produce surgical anaesthesia in the rat. This anaesthetic regimen produced significant respiratory depression (P less than 0.01) and animals did not regain their righting reflex until 193 +/- 21 min (mean +/- 1 SD) after injection. Administration by intraperitoneal injection of atipamezole, a specific alpha 2-adrenoceptor antagonist (1 mg/kg) mixed with a mu antagonist/k agonist opioid (nalbuphine, 2 mg/kg or butorphanol 0.4 mg/kg), resulted in a rapid (less than 8 min) reversal of anaesthesia and the associated respiratory depression, and apparent full recovery of consciousness.

Abstract
Cerebral infarction in Wistar rats was induced by photochemical method. A photochemical reaction was produced by the photosensitive agent rose bengal under the effects of green light (560 +/- 60 nm). This reaction released free radicals which may damage the endothelium of cerebral vessels and induce platelet aggregation, and then may cause thrombosis in cerebral parenchymal vessels. There were typical changes of thrombosis and ischemic necrosis in the irradiated region of the cerebrum under light and electron microscopy. Serial pathologic findings suggested that the critical phase of progressive necrosis lies at the time of 1-6 hours after cerebral ischemia induced photochemically. Therefore, effective protection of the brain is important in the early stage of cerebral ischemia.

Abstract
A cDNA clone encoding rat intrinsic factor (IF), pIFQ, has been inserted into the eukaryotic expression vector pSVL and used to transfect COS-1 cells. The IF produced by the transfected cells was secreted nearly exclusively into the medium at concentrations of 0.1-0.2 micrograms/ml. Tunicamycin treatment (1-10 micrograms/ml) completely blocked N-linked glycosylation but had no effect on IF secretion. The secreted glycosylated IF retained all the properties of native IF, i.e., high affinity for cobalamin (Cbl) and for the IF-Cbl receptor and relative resistance to low pH and to proteolysis. The nonglycosylated IF also retained these properties except that it was more protease sensitive. The protease degradation was prevented by the presence of the ligand Cbl. The presence of carbohydrate may play a role in protecting IF from digestion by pancreatic proteases in the intestinal lumen.

Abstract
A method is described for the determination of aldicarb and its metabolites (the sulphoxide and sulphone) in urine by gas chromatography with flame photometric detection (GC-FPD). The sample was concentrated with a column containing activated charcoal and Florisil, and then eluted with dichloromethane-acetone (1:1, v/v). The aldicarb and aldicarb sulphoxide in the eluate solution were oxidized to aldicarb sulphone and the total sulphone concentration was determined by GC-FPD after extraction with dichloromethane and clean-up with an activated charcoal column. The detection limit was 0.0024 mg/l. The mean recoveries from spiked urine in the range 0.04-0.12 mg/l were 90.9%, 86.6%, 92.6% for aldicarb, aldicarb sulphoxide and aldicarb sulphone, respectively.

Abstract
Two strains which belong to the same serotype of Shigella were isolated from the bloody-pus stool of two patients (in 1986) and is reported in this paper. The results were identical both showing agglutination in low titer with serotype 8 of S. dysenteriae and serotype 4 of S. boydii when the two strains were checked well with all kinds of diagnostic antisera and vice versa, ie the antisera produced by the two strains were also checked well with sera prepared with the representative strains of all Shigella spp. No cross agglutination with O6, O7, and O150 of E. coli were found. Consequently, It appears to be a new serotype of Shigella. These two strains possess the ability of causing keratitis in guinea-pigs as well as invading epithelial cells, the DNA of both strains in agarose-electrophoresis showed a large plasmid, indicating that they are virulent strains possessing invasive ability. It was concluded that these two strains belonged to Shigella boydii as they fermented mannitol and non-related antigenically with Shigella flexneri. Since serotype 1-18 of S. boydii have been reported recently, we propose that this new serotype should be serotype 19 of Shigella boydii.

Abstract
Natural killer (NK) activities of fresh and IL-2-precultured peripheral blood mononuclear cells (PBMC) were investigated in 13 elderly subjects before and after thymopentin (TP-5) treatment and in 12 age-matched controls. The NK activity of fresh PBMC was found to be significantly higher in subjects given TP-5 at 50 mg s.c. three times per week for one month. Conversely, this type of treatment with TP-5 did not significantly modify the cytotoxic capacity of IL-2-precultured PBMC.

Abstract
We studied Leu 7+ cell distribution and natural killer (NK) activity in the peripheral blood of six patients who had peripheral neuropathy and monoclonal IgM protein directed against myelin-associated glycoprotein (anti-MAG IgM). We did not find any difference between patients and control subjects (healthy or polyneuropathic, some with IgM monoclonal paraprotein but without anti-MAG activity). The presence of autologous sera did not interfere with these results. We noted an increase in Leu 11+ cell percentages after pre-incubation of the patient cells with autologous sera but the phenotypes of cells from control subjects did not change after incubation with autologous or patient sera.

Abstract
42 patients with carcinoma of gastric cardia treated by HPD are reported. The endoscopic biopsy specimens of these patients were classified histologically before treatment. There were 2 papillary adenocarcinoma (PAC), 14 well differentiated adenocarcinoma (WDAC), 11 moderate differentiated adenocarcinoma (MDAC), 5 poor differentiated adenocarcinoma (PDAC), 6 mucinous adenocarcinoma (MAC), 1 undifferentiated carcinoma (UDC) and 3 squamous cell carcinoma (SCC). After four weeks' treatment, reexaminations by endoscopy and biopsy were done in 39 patients and operation were performed on three. Histologic changes following the treatment were degeneration, necrosis of tumor cells, and infiltration of lymphocytes and plasmacytes in the stroma to different degrees. The histologic changes were graded into H0, H1, H2 and H3 by the authors. Grades H0, H1 are considered as noneffective and grades H2, H3 as effective. Of 42 patients, 10 were H0, 21 H1, 8 H2 and 3 H3. The overall effective rate was 26.2% (11/42) which was correlated with the histologic type of carcinoma. Thus, 21.4% (3/14) of WDAC, 18% (2/11) of MDAC, 40% (2/5) of PDAC, 50% (3/6) of MAC and 100% (1/1) of UDC responded well to the treatment, but all SCC and PAC were refractory. It should also be noted that the HPD treatment was effective in patients with tumor infiltrations relatively limited and superficial in the gastric wall, but was unsatisfactory in patients with wider and deeper infiltrations.

Abstract
Ten monoclonal antibodies (McAbs) have been produced against the cationic peroxidase from peanut suspension cell culture. Eight of these antibodies were found to be of the immunoglobulin (Ig)G(1) subclass and two were of IgA subclass. A combination of competitive enzyme-linked immunosorbent assay, Western blotting analysis, and direct antigen-binding assay revealed that the antibodies are directed against four different epitopes on the cationic peroxidase and the McAbs can be subdivided into four groups. Only group A inhibits peroxidase activity. Group B and D bind equally well to the native and the denatured form of cationic peroxidase, whereas the remaining McAbs react with more or less reduced affinity to the denatured antigen. Group C probably recognizes a conformation-dependent epitope. All the McAbs cross react weakly with the anionic peanut peroxidase, suggesting a structural nonidentity as well as some similarity between these two peroxidase isozymes. Cross reactivities of these McAbs with peroxidases of various plant species were also demonstrated.

Abstract
The transcriptional enhancer sequence has recently been demonstrated in the hepatitis B viral genome. This enhancer sequence has also been shown to increase the activity of HBcAg gene promoter. Using the chloramphenicol acetyltransferase gene expression system, we demonstrated that the intrinsic promoter activity of HBsAg gene promoter was stronger than that of HBcAg gene promoter in both human hepatoma cell lines, Hep3B and HuH-7. Furthermore, we showed that the HBV enhancer sequence not only stimulated the HBcAg gene promoter activity, but also stimulated the HBsAg gene promoter activity in both Hep3B and HuH-7 cells. The enhancer sequence increased the HBsAg gene promoter activity 20-fold in both Hep3B and HuH-7 cell lines, while the increase of the HBcAg gene promoter was 2- and 8-fold in Hep3B and HuH-7 cells, respectively.

Abstract
The hemodynamic and electrophysiologic alterations induced by ionic contrast agents during cardiac angiography are well described. Recently nonionic contrast agents have become available for cardiac angiography. To evaluate the safety of these new agents, a double-blind randomized study was performed comparing a new nonionic agent (iopamidol) with a commonly used ionic contrast agent (Renografin-76). Eighty-one patients undergoing left ventriculography and coronary angiography were included; 41 received iopamidol and 40 received sodium meglumine diatrizoate (Renografin-76). After left ventriculography, there was a decrease in the arterial pressure with both contrast agents. However, the severity and the duration of hypotension were both significantly greater with Renografin-76 compared with the new nonionic agent (p less than 0.001). After selective injections of the coronary arteries, electrocardiographic analysis demonstrated that the increase in the QT interval (p less than 0.0002) and the changes in both the ST segment and T wave amplitude (p less than 0.001) were significantly greater in the Renografin-76 group compared with the iopamidol group. During coronary angiography, 8 of the 40 patients receiving Renografin-76 required temporary pacing for sinus pauses of 2.5 seconds or more, and 2 of the 40 also developed ventricular fibrillation. None of the 41 patients receiving iopamidol had these complications. This report demonstrates that the electrocardiographic changes, the severity and duration of hypotension and the incidence of serious arrhythmias are significantly greater with Renografin-76 than with iopamidol. Thus, this new nonionic agent appears to enhance the safety of cardiac angiography.

Abstract
Three cases of solitary hemangioma of the choroid are reported. One patient, followed for 22 years, was untreated, and the natural course was chronic and progressive. Although the tumor itself did not enlarge markedly, the serous detachment of the retina was extensive. Cystoid degeneration and deterioration of visual acuity was the final result. Two patients were treated with argon green laser and then followed for eight years and one year, respectively. Laser photocoagulation is the method of choice. Clinical characteristics and differential diagnosis are discussed. Early diagnosis and early treatment are important for preserving vision in an eye affected with hemangioma of the choroid.

Abstract
Membrane markers expressed by a transplantable granulocytic leukemia induced in inbred strain 13 guinea pigs by N-nitroso-N-butylurea have been investigated by serologic and immunochemical methods. Although the leukemic myeloblasts have no detectable surface immunoglobulin or Fc receptors, they have been found to synthesize and express membrane antigens encoded for by the I-region of the major histocompatibility complex. Despite the presence of Ia antigens, these cells do not stimulate allogeneic T lymphocytes in the mixed lymphocyte reaction nor are they able to present soluble antigen to immune T cells. The presence of Ia antigens on immature myeloid cells suggests that these proteins may be important in cellular functions beyond those identified in the cellular immune system.

Abstract
Immune serum, obtained from animals that had survived sublethal challenge with RE virus, was very effective in achieving tumor cures in chickens infected with this virus. The therapeutic effect could also be obtained by the immunoglobulin fraction of immune serum. The serum did not influence the development of an unrelated malignancy. Serotherapy studies in Bx and Tx recipients indicate that the B-cell or T-cell system of the host does not significantly contribute to the curative activity of immune serum. Absorption studies show that the curative effect is mediated by antibodies to tumor-associated transplantation antigens on tumor cells, not by antiviral antibodies.

Abstract
A simple and sensitive method of measuring the thermally induced index changes arising from absorption of a laser beam in a low-loss material is described. The sample is placed outside the laser cavity, but at the position of minimum radius of curvature of the wavefront, which is a confocal distance behind the waist. It is estimated that the method is sensitive enough to measure absorption coefficients of the order of 5 x 10(_6) cm(_1) and it is shown experimentally to have good accuracy on low-loss materials. A detailed comparison of sensitivity and accuracy estimates is given for the various published thermal-lens methods for measuring low absorption coefficients.Although the method is illustrated for the thermal effect, it is applicable to other nonlinear index changes induced by laser beams.
