Abstract
The effects of methamphetamine and morphine on the vertical (VMA) and the horizontal motor activities (HMA) in male ddY mice (six weeks of age) was investigated between 9:00 and 13:00, using an apparatus which can differentiate spontaneous motor activity into VMA and HMA, measuring their activities simultaneously. VMA and HMA were evaluated by counting the number of times that an infrared ray was blocked by the mouse in the activity cage. Nine infrared photo-couplers were used to measure the VMA and one to measure the HMA. All measurements were taken at 10 min intervals during the 180 min period after subcutaneous injection of methamphetamine (0.1, 1 and 10 mg/kg) or morphine (2, 10 and 50 mg/kg). A small dose of methamphetamine (0.1 mg/kg) did not exert influence on the counts of the VMA and the HMA, whereas a large dose enhanced both activities, especially at 10 mg/kg, where each activity showed qualitatively different biphasic patterns. On the other hand, three doses of morphine significantly inhibited the VMA for 20 min after administration, while morphine at 2 mg/kg depressed the HMA for 10 min after administration and at 10 mg/kg or more markedly enhanced it during the 180 min observation period. These results show that different doses of methamphetamine and morphine exert different effects on the VMA and the HMA in mice.

Abstract
A simple apparatus using the infrared ray, which can divide spontaneous motor activity (SMA) of mice into two behavioral components, a vertical movement (VM) and a horizontal movement (HM) was designed. VM and HM were evaluated by counting the number of times that infrared rays were blocked by the mouse in the activity cage [300(H) X 260(D) X 130(W) mm] with 9 infrared photo-couplers for measuring VM and one infrared photo-coupler for measuring HM. When methamphetamine (MAM) was subcutaneously administered to mice pretreated with saline (0.1 ml/10 g, sc) for 3 days, VM and HM were as follows: 1) At 0.1 mg/kg of MAM, the same level of activity was observed as with saline. 2) At 1.0 mg/kg of MAM, increased activity was noted. 3) At 10 mg/kg of MAM, a marked increase was noted, showing more enhancement of HM than VM, which had developed into a stereotyped behavior. In summary, this new apparatus was found capable of dividing the SMA of mice into the two behavioral patterns of VM and HM, and providing their measurements.

Abstract
Dipeptidyl aminopeptidase activity was found in the culture medium of Bacteroides gingivalis 381. The enzyme, hydrolyzing glycylprolyl-4-methylcoumaryl-7-amide, was purified 750-fold from culture medium by ammonium sulfate precipitation, Sephadex G-200 gel filtration, and DEAE Bio Gel A column chromatography. The molecular weight, determined by gel filtration, was approximately 160,000. The isoelectric point of the enzyme, estimated by isoelectric focusing using polyacrylamide disk gel electrophoresis, was about pH 6.2. The optimum pH of the enzyme was about 8.0, and the Km value was 0.05 mM. The enzyme activity was strongly inhibited by phenylmethylsulfonylfluoride and diisopropylfluorophosphate. The purified enzyme specifically cleaved glycylprolyl dipeptide from partially digested type I collagen.

Abstract
Piperine and two of its derivatives, antiepilepsirine (AE or 3,4-methylendioxycynnamoylpiperine) and compound 7448 (N-isopropyl 3 (4 chloro-phenyl) propenoylamide) are very effective in stimulating serotonin (5HT) synthesis. AE raises the ratio of free-to-bound tryptophan (TP) in plasma and induces a long-lasting increase of this aminoacid in brain. At the same time in striatum and limbic area it causes a lasting increase in 5 hydroxyindolacetic acid (5HIAA) a 5HT metabolite and to a lesser extent, an increase in the levels of the monoamine itself. Together with this action on 5HT metabolism we found that AE caused release of 3H-5HT from an in vitro synaptosomal preparation. It thus appears that piperine and its derivatives AE and compound 7148 affect the central serotonergic system.

Abstract
We applied the tagged-particle method or the saccharin method or both to the nasal mucociliary clearance. There was no effect of ageing on the transport time of saccharin in control subjects of ages under 60, and 70% of control subjects of ages more than 60 had the same transport time as that obtained in younger control subjects. The significant inverse correlation between the mucociliary transport rates with the particle method and the transport time with the saccharin method were established in control subjects, but not, however, in patients with chronic sinusitis. The mucociliary transport rates were measured under non-physiologic conditions of the nose: laryngectomy, chronic sinusitis, Sjögren's syndrome, and Kartagener's syndrome.

Abstract
The effect of insoluble glucan synthesized by Streptococcus mutans on [3H]arachidonate metabolites secretion from peritoneal macrophages was studied. Insoluble glucans stimulated [3H]arachidonate release and secretion of prostaglandin E2 and thromboxane B2 from macrophages. In contrast, commercial soluble glucan (dextran) did not induce [3H]arachidonate release.

Abstract
Nasal mucociliary clearance was measured in both healthy subjects and patients with chronic sinusitis using saccharin granule technique. Nasal mucociliary transit time (ST) was significantly slower in the patients with chronic sinusitis compared with that in controls (p less than 0.005). Nasal mucus collected from each nasal cavity was used for in vitro bullfrog palate clearance studies and compared to the in vivo nasal ST. Mucociliary clearance rate (MTR) on frog palate was 12.5 +/- 2.5 mm/min in the mucus from control subjects, 6.1 +/- 1.5 mm/min in the mucus from the patients. The difference was statistically significant (p less than 0.005). The MTR on frog palate in the patients whose nasal ST was within normal range was significantly slower than that in controls (p less than 0.005), but not significantly different from that in the patients whose nasal ST was over the normal range. These results suggest that the nasal mucous properties which decreased the mucociliary clearance on frog palate did not contribute to the mucociliary clearance of the patients who had a normal one. No significant correlation existed between MTR on frog palate and nasal ST in both control and chronic sinusitis. In chronic sinusitis patients, decelerated nasal ST was recovered significantly by normal saline nebulization compared with the value before the nebulization (p less than 0.01). None of the significant change of ST was observed in control before and after the nebulization.

Abstract
The subunit structure of islet-activating protein (IAP), pertussis toxin, has been analyzed to study a possibility that this protein is one of the A-B toxins [Gill, D. M. (1978) in Bacterial Toxins and Cell Membranes (Jeljaszewicz, J., & Wadstrom, T., Eds.) pp 291-332, Academic Press, New York]. Heating IAP with 1% sodium dodecyl sulfate caused its dissociation into five dissimilar subunits named S-1 (with a molecular weight of 28 000), S-2 (23 000), S-3 (22 000), S-4 (11 700), and S-5 (9300), as revealed by polyacrylamide gel electrophoresis; their molar ratio in the native IAP was 1:1:1:2:1. The molecular weight of IAP estimated by equilibrium ultracentrifugation was 117 000 which was not at variance with the value obtained by summing up molecular weights of the constituent subunits. The preparative separation of these IAP subunits was next undertaken; exposure of IAP to 5 M ice-cold urea for 4 days followed by column chromatography with carboxymethyl-Sepharose caused sharp separation of S-1 and S-5, leaving the other subunits as two dimers. These dimers were then dissociated into their constituent subunits, i.e., S-2 and S-4 for one dimer and S-3 and S-4 for the other, after 16-h exposure to 8 M urea; these subunits were obtained individually upon further chromatography on a diethylaminoethyl-Sepharose column. Subunits other than S-1 were adsorbed as a pentamer by a column using haptoglobin as an affinity adsorbent. The same pentamer was obtained by adding S-5 to the mixture of two dimers. Neither this pentamer nor other oligomers (or protomers) exhibited biological activity in vivo. Recombination of S-1 with the pentamer at the 1:1 molar ratio yielded a hexamer which was identical with the native IAP in electrophoretic mobility and biological activity to enhance glucose-induced insulin secretion when injected into rats. In the broken-cell preparation, S-1 was biologically as effective as the native IAP; both catalyzed ADP-ribosylation of a protein in membrane preparations from rat C6 glioma cells. In conclusion, IAP is an oligomeric protein consisting of an A (active) protomer (the biggest subunit) and a B (binding) oligomer which is produced by connecting two dimers by the smallest subunit in a noncovalent manner. Rationale for this terminology is discussed based on the A-B model.
