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.
