Abstract
In an effort to develop new types of antiulcer agents, we synthesized a series of novel 2-[omega-(thioureido)alkyl]- and 2-[omega-(cyanoguanidino)alkyl]-3(2H)-pyridazinone derivatives. All target compounds were evaluated for gastric antisecretory activity in the pylorus-lygated rat by the method of Shay, and selected compounds were evaluated in the stress-induced ulcer test in rats. Structure-activity relationships were established. Two series of the compounds had significant activity in antisecretory and/or antiulcer tests. The molecular features essential for the activities are a thiourea group or a 2-cyanoguanidine group, a phenyl group in the C-6 position of the 3(2H)-pyridazinone ring, a four-carbon chain length between the 3(2H)-pyridazinone ring and the functional group, and a methyl group at the N-3 position of the functional group. Among them, the three thiourea derivatives (24, 26, and 38) and the six 2-cyanoguanidine derivatives (61, 62, 65, 75, 85, and 86) had the most potent antisecretory and/or antiulcer activities. These compounds are not histamine H2-receptor antagonists.

Abstract
Transrectal ultrasonography was done in 19 healthy men and 236 patients with benign prostatic hyperplasia to elucidate the pathomorphology of the prostate and to determine preoperative prostatic size in patients who underwent transurethral prostatectomy. We found that the ultrasonographic examination allowed for an accurate estimation of the prostatic weight and a good assessment of the completeness of resection of the prostatic adenoma.

Abstract
Liposomes containing penicillinase or cephalosporinase were prepared from the phospholipids of Escherichia coli. After free beta-lactamase was inactivated by clavulanic acid or penicillanic acid sulfone followed by separation of inactivated enzyme and inhibitor from liposomes by gel filtration, the permeability of these liposomes to ampicillin, cefazolin and cephaloridine was estimated by measuring the hydrolysis of these antibiotics by the entrapped enzymes. The permeability parameter C (minute-1 microM lipid-1) of ampicillin, cefazolin and cephaloridine was calculated to be 2.35 X 10(-4), 0.33 X 10(-4) and 0.52 X 10(-4), respectively. The lipid bilayer permeability of these antibiotics was also measured by using the liposomes containing these antibiotics. About half of the initially entrapped ampicillin was released from the liposomes within 80 minutes, while no significant release of cefazolin and cephaloridine could be detected during the same period. These results clearly indicates that the lipid bilayer membrane is more permeable to ampicillin than cefazolin and cephaloridine, and they are consistent with the observations of Sawai et al., who showed that ampicillin was a more effective antibacterial drug than cefazolin and cephaloridine against the porin-deficient mutants.

Abstract
In an effort to develop new types of antiulcer agents, a series of novel 3(2H)-pyridazinone derivatives and related analogues was synthesized. Substituted 3(2H)-pyridazinones and their 4,5-dihydro analogues were alkylated by omega-haloalkyl cyanides at the N-2 position under phase-transfer catalytic reaction, and the nitrile group was converted to the thio amide group by treatment with hydrogen sulfide alone or with the appropriate primary or secondary amines. Various substituents were introduced on the nitrogen of thio amide, on the carbon in the side chains, and on the 3(2H)-pyridazinone ring. The synthesized compounds were evaluated for gastric antisecretory activity in the pylorus-ligated rat, and selected compounds were applied to experimental ulcer models, such as Shay's, aspirin-induced, and stress-induced ulcers in the rat. Structure-activity relationships are discussed. 3(2H)-Pyridazinones with a C-6 phenyl group and an N-2 alkyl side chain with a terminal thio amide group (48, 49, 51, and 52) were the most potent among the compounds tested.

Abstract
The incidence and distribution of amyloid deposits in aged tongues obtained from 107 necropsies over 60 years of age were examined. Thirty-nine tongues were affected with amyloid deposits and the overall incidence was 36.4%. The incidence increased with each advancing decade, and the group over 90 years old showed the highest incidence of 59.6%. Although the amount of amyloid deposits differed in each case, severely affected cases were most frequently found in the advanced decades. Amyloid deposits were almost always confined to blood vessels, especially arterioles and arteries. They occasionally occupied the entire wall and occluded the lumen. Blood vessels affected with amyloid were usually located in the muscle layers of the tongue. Vessels in the subepithelial layer and lingual glands were, however, sometimes affected. Amyloid deposits were resistant to Congo red staining with the potassium permangante method, and stained positively with DMAB. The present study suggested that the tongue is an important organ as to the appearance of amyloid deposits in elderly persons.

Abstract
We investigated the mechanism of the elevation of serum corticosterone level by 4-ethoxy-2-methyl-5-morpholino-3(2H)-pyridazinone (M73101) and its participation in the anti-inflammatory action. M73101 when given to rats intraperitoneally at doses of 50-200 mg/kg, caused an increase in serum and adrenal corticosterone in a dose-dependent manner. Oral administration of 200 mg/kg of M73101 also elevated the serum corticosterone level. Such action of M73101 was completely abolished by adrenalectomy, hypophysectomy, or the pretreatment with pentobarbital and morphine. In vitro experiment demonstrated that M73101 had no direct effect on adrenocortical function. These results indicate that the response to M73101 must be medicated through the release of ACTH from the adenohypophysis, which is probably due to the secretion of corticotropin releasing factor from the hypothalamus. M73101 at an oral dose of 200 kg/mg significantly decreased the volume of exudative fluid and the number of leucocytes in carrageenin-induced pleurisy of intact rats. However, the inhibitory action of this drug on cell mobilization decreased by adrenalectomy but not on exudative fluid, indicating that anti-inflammatory actions of M73101 may be due in part to pituitary-adrenocortical stimulation.

Abstract
Little is known about the pathogenesis of pancreatolithiasis, and although several theories have been proposed, no experimental models of pancreatic calculi production are documented in the literature. This study examines such a model in which partial or complete pancreatic duct obstruction was surgically created in dogs. We found that (1) pancreatic calculi were demonstrated in 46.7% of the dogs (14 of 30) with partial outflow obstruction for 4 months or longer; (2) no pancreatic calculi were found in any of the dogs with complete pancreatic duct obstruction; (3) all calculi produced were localized in the ductal system; (4) the organic and inorganic composition of canine and human pancreatic calculi were quite similar; and (5) connective tissue proliferation and mucous cell metaplasia of the ductal epithelium, often seen in association with clinical pancreatolithiasis, are also detected in the pancreata of dogs that have had partial obstruction of pancreatic excretion. These findings suggest that an experimental model of pancreatolithiasis can be accomplished in dogs by the partial obstruction of pancreatic excretion.

Abstract
A case of calcifying epithelial odontogenic tumor was studied histochemically and electron microscopically. This case was characterized by an abundant amount of homogeneous substance and the presence of numerous clear cells. Although the homogeneous substance was shown to be an amyloid material in nature, it was supposed to be an extracellular product of the epithelial tumor cells. The clear cells contained abundant glycogen granules in their cytoplasm.

Abstract
Hyaline bodies of odontogenic cyst were examined by histological, histochemical and electron microscopic observations. They were seen only in odontogenic cysts and their prevalence was 6.9% in 576 cases of the cysts. They occurred most frequently within the epithelial lining, but a few bodies were observed in the connective tissue walls. Histochemical reactions of hyaline bodies were similar to those of dental cuticles, but differed from keratin. Ultrastructurally, hyaline bodies were typed into two forms: lamellated and homogeneous. The lamellated bodies were composed of alternate electron-dense and electron-lucent layers. The homogeneous bodies were occasionally formed around granular material, mineralized masses and cholesterol clefts. Hyaline bodies adjoined epithelial cells via a basal lamina-like structure and half-desmosomes. Epithelial cells containing well-developed, rough surfaced, endoplasmic reticulum were seen adjacent to hyaline bodies. Ferritin-like granules were found in the cytoplasm of epithelial cells near hyaline bodies. By electron probe X-ray microanalysis, inorganic elements within the ferritin-like granules were the same in constitution as those in the outermost electron-dense layer of the lamellated bodies. By scanning electron microscopy, hyaline bodies displayed ellipsoidal and stick-like shapes. The present study suggested that hyaline bodies are particular products formed by odontogenic epithelium.

Abstract
Lethally irradiated mice were injected with 1 x 10(5) normal bone marrow cells taken from mice of the same strain. They were divided into two groups: One was given chloramphenicol (CAP) or thiamphenicol (TAP) in an early stage after marrow transfusion and the other in a later stage. In both groups, more prominently in the former group, some ultrastructural changes were recognized in mitochondria of the early erythroblasts. Mitochondria increased in number and became swollen with electron lucent matrix and paucity of cristae. Condensed mitochondria described in earlier reports were never observed. Intermediate or late erythroblasts seen only in the latter group did not show such alterations. Mitochondrial changes in the early erythroblasts were considered to reflect the dose-related toxic effects of CAP and TAP, and it is assumed that these drugs affect the development of erythroblasts in a very early stage.

Abstract
Cell surface-associated changes in behaviour of cultured cells on partition in an aqueous two-phase polymer system were studied using FM3A cell line (a cultured mammary cancer of mouse) with respect to aging. The aqueous polymer system consisted of dextran, polyethyleneglycol and sodium phosphate, equilibrated at 6 degrees C to separate into two phases. Enzyme treatment of cells with neuraminidase reduced cell electrophoretic mobility, as well as the cell partition ratio. Hyaluronidase produced no observable effects on partition and cell electrophoretic mobility, suggesting that the partition is related to culture time was similar for both cell electrophoretic mobility and cell partition, showing a rise and fall of charge-associated cell surface change during cell growth, the maxium occurring at the beginning of exponential growth. This change was reflected in the pattern of countercurrent distribution of the cells in respective stages of growth. Countercurrent distribution with our two-phase system is expected to be capable of fractionating cell populations according to cell surface properties.

Abstract
Relationships between the infusion speed and lethal dose of several amino acid solutions of various concentrations were studied in male Sprague Dawley rats. When the amino acid solutions were continuously infused at various speeds, a functional relationship between the dose producing a cardiac arrest (DCA) and infusion speed was established. The DCA/infusion speed was characterized by two ranges with an increasing DCA as increase or decrease of infusion speed and by its intermediate range of a flat minimum with a practically constant DCA regardless of varying the infusion speed. A practically constant LD50 was obtained in the infusion of each amino acid solution within the infusion speed in the intermediate range. The LD50 of each amino acid solution was dependent on the crystalloid osmotic pressure.

Abstract
Lethally irradiated mice received a transfusion of normal bone marrow cells from the same strain mice. The transfused colony-forming cells (stem cells) were settled in the spleen of the recipient and proliferated in it into erythroblast colonies. Some of these mice were given chloramphenicol or thiamphenicol for 7 days after marrow cell transfusion. Annulate lamellae were frequently observed exclusively in the erythroblasts of the mice received a injection of thiamphenicol.
