Abstract
We examined the intracellular localization of sugar residues of the rat gastric surface mucous cells in relation to the functional polarity of the cell organellae using preembedding method with several lectins. In the surface mucous cells, the nuclear envelope and rough endoplasmic reticulum (rER) and cis cisternae of the Golgi stacks were intensely stained with Maclura pomifera (MPA), which is specific to alpha-Gal and GalNAc residues. In the Golgi apparatus, one or two cis side cisternae were stained with MPA and Dolichos biflorus (DBA) which is specific to terminal alpha-N-acetylgalactosamine residues, while the intermediate lamellae were intensely labeled with Arachis hypogaea (PNA) which is specific to Gal beta 1,3 GalNAc. Cisternae of the trans Golgi region were also stained with MPA, Ricinus communis I (RCA I) which is specific to beta-Gal and Limax flavus (LFA) which is specific to alpha-NeuAc. Immature mucous granules which are contiguous with the trans Golgi lamellae were weakly stained with RCA I, while LFA stained both immature and mature granules. The differences between each lectin's reactivity in the rough endoplasmic reticulum, in each compartment of the Golgi lamellae and in the secretory granules suggest that there are compositional and structural differences between the glycoconjugates in the respective cell organellae, reflecting the various processes of glycosylation in the gastric surface mucous cells.

Abstract
Squamous-cell carcinoma antigen (SCC antigen), formerly referred to as TA-4, is closely related to the grade of differentiation. Immunohistochemical studies have demonstrated that SCC antigen is also increased in the keratinizing or large-cell nonkeratinizing type of squamous-cell carcinoma but not in the small cell type. On the other hand, the appearance rate of SCC antigen in the blood circulation is almost the same in these three types of squamous-cell carcinoma. The present study was conducted to clarify the discrepancy in the production and release of this tumor marker using a squamous-cell carcinoma cell line, SKG-IIIa. SKG-IIIa cells were treated with 10 microM 5-azacytidine, a potent hypomethylating agent, to obtain several sublines with different behavior in the production of SCC antigen, and cloned by a limiting dilution technique. One subline (B-5) released significantly greater amounts of SCC antigen into the incubation medium as compared with other sublines (A-5). In in vivo studies, groups of nude mice received subcutaneous injections of the A-5 or B-5 subline, and the serum SCC antigen levels were determined after the animals exhibited palpable tumors. The serum levels of SCC antigen were significantly higher in the animals inoculated with the B-5 cells than in those inoculated with the A-5 cells. On the other hand, flow-cytometric analysis and immunohistochemical studies using a polyclonal antibody revealed that the intracellular contents of SCC antigen were greater in the A-5 cells than in the B-5 cells. Radioautography was performed using a 125I-labeled monoclonal antibody specific against the acidic fraction of this marker, a dominant form released outside the cells, which revealed that the production of the acidic fraction was somewhat greater in the B-5 cells than in the A-5 cells. These results suggest that the production and release of SCC antigen are different phenomena in squamous-cell carcinoma and that the release of SCC antigen is likely influenced by the production of the acidic fraction.

Abstract
We investigated the ultrastructure of blood group antigens A, B, and H in human eccrine glands by means of the immunogold labeling technique. Blood group antigens A, B, and H were found in the Golgi apparatus, secretory granules, and over the apical and basolateral cell membranes of dark cells of eccrine glands depending on the blood group phenotype of the donors. Both A and B antigens were found in the dark cells of AB donors. The labeling pattern of the Golgi stacks seemed to have a polarity whereby the anti-blood group A antibody labeled all the stacks, whereas anti-blood groups B and H bound to the trans side of the Golgi complex. These observations suggest that the blood group substances are secreted into the lumen after being processed through the Golgi apparatus and the immature and mature granules in the dark cells of human eccrine glands.

Abstract
The development and maturation of fundic glands of Wistar rats were studied using Griffonia simplicifolia agglutinin-II (GSA-II) histochemistry at the light microscopic and electron microscopic levels. In adult rats, mucous neck cells and cells intermediate between mucous neck cells and chief cells were specifically labeled with GSA-II, whereas other fundic gland cells were virtually negative. Ontogenetic studies revealed that GSA-II positive cells appeared at the bottom of the gland by 21 days of gestation. With differentiation and aging, the elongation of the fundic gland continued, and the labeling intensity of the mucous neck cells increased by 3 weeks after birth. Cells intermediate between mucous neck cells and chief cells were discernible from 3 days after birth. Typical mucous neck cells appeared at 3 weeks after birth, when their labeling intensity with colloidal gold (CG) particles approximated that of adults. On the other hand, the reactive cell population gradually moved from the bottom toward the middle portion of the gland. Finally, the reactive cells were localized at the neck portion of the fundic gland. These results suggest that GSA-II is a valuable marker for studying mucous neck cells and both their precursor cells and their derivatives.

Abstract
Microtubule-associated protein 2 (MAP 2) purified from microwave-irradiated rat head contained about 46 esterified phosphates (mole/mol), which were not bound covalently to lipids and did not assemble with microtubules. After some phosphates were released by calf intestinal alkaline phosphatase, the phosphate content of MAP-2 decreased to 16 mol of phosphate and the protein assembled in vitro. MAP-2 purified after microtubule assembly cycles and also the cytosolic heat-stable fraction without assembly cycles had 10 mol of phosphate, and both assembled with microtubules. The MAP-2 with 46 phosphates and that with 10 had different pI in isoelectric focusing, but the components, MAP-2a and -2b, were always near each other. In high-pressure liquid chromatography, MAP-2 containing 46 mol of phosphate appeared after that 10 mol of phosphate. Phosphoserine, phosphothreonine, and phosphotyrosine were recovered from tryptic digestion of MAP-2 with 46 mol of phosphate. These findings suggest that two kinds of MAP-2, one with 46 phosphates and not bound to tubulin and the other with 10-16 phosphates and bound to tubulin, are present in the living rat brain.

Abstract
ADP-ribosylation of regulatory proteins is an important pathological mechanism by which various bacterial toxins affect eukaryotic cell functions. While diphtheria toxin catalyses the ADP-ribosylation of elongation factor 2, which results in inhibition of protein synthesis, cholera toxin and pertussis toxin ADP-ribosylate Ns and Ni, respectively, the GTP-binding regulatory components of the adenylate cyclase system, thereby modulating the bidirectional hormonal regulation of the adenylate cyclase. Botulinum C2 toxin is another toxin which has been reported to possess ADP-ribosyltransferase activity. This extremely toxic agent is produced by certain strains of Clostridium botulinum and induces hypotension, an increase in intestinal secretion, vascular permeability and haemorrhaging in the lungs. In contrast to botulinum neurotoxins, the botulinum C2 toxin apparently lacks any neurotoxic effects. Here we report that botulinum C2 toxin ADP-ribosylates a protein of relative molecular mass 43,000 (43K) in intact cells and in cell-free preparations. We present evidence that the 43K protein substrate is actin, which is apparently mono-ADP-ribosylated by the toxin. Botulinum C2 toxin also ADP-ribosylated purified liver G-actin, whereas liver F-actin was only poorly ADP-ribosylated and skeletal muscle actin was not ADP-ribosylated in either its G form or its F form. ADP-ribosylation of liver G-actin by botulinum C2 toxin resulted in a drastic reduction in viscosity of actin polymerized in vitro.

Abstract
C2 toxin elaborated by Clostridium botulinum type C is composed of two dissimilar protein components, designated components I and II. Component I of the toxin caused ADP-ribosylation of a protein of Mr 45,000 in chicken tissue homogenates and also purified nonmuscle but not muscle actin. The endogenous ADP-ribosylation of intracellular actin with C2 toxin was correlated with the morphological change in intact culture cells caused by the toxin. These results indicate that the biological activity of the toxin involves a novel enzymatic activity of component I, which catalyzes the preferential ADP-ribosylation of nonmuscle actin of the target cells.

Abstract
Microtubule-associated protein 2 (MAP-2) purified after microtubule assembly cycles from bovine brain had been shown to contain about 10 esterified phosphates (mol/mol), which were relatively phosphatase resistant and essentially confined to the projection domain which contributes to the visible arms on microtubules. The kinase responsible for phosphorylating these sites had not been identified. We have approached this question by using a phosphatase that releases the bulk of these residues and then determining which kinase can now add additional residues corresponding to those released. Three kinases were chosen because of their abundance in brain and/or proximity to microtubules. Of these only Ca/phospholipid-dependent kinase was able to recognize the previously occupied sites. We also found that MAP-2 isolated from rat brain without assembly cycles contained more phosphate than previously recognized, greater than 30 mol/mol, suggesting that 20 of these had been inadvertently released by phosphatase during assembly cycles. All 3 kinases (Ca/phospholipid-dependent, cAMP-dependent, and Ca/calmodulin-dependent kinase II) recognized more sites in the bovine than in the rat MAP-2.

Abstract
Erythrocyte surface membrane sialyl residues were investigated by means of affinity cytochemistry using the avidin-biotin complex technique. Mild oxidation with the periodate (MO)-biotin hydrazide (BHZ)-ferritin avidin conjugate (FAv) sequence revealed numerous ferritin particles on erythrocytes from healthy donors. The ferritin particles attached on the perpendicularly sectioned membrane were seen at an average distance of 10 to 12 nm from the outer dense leaflet of the cell membrane. Pretreatment with neuraminidase followed by the MO-BHZ-FAv sequence almost eliminated erythrocyte ferritin labeling. Erythrocytes from diabetic patients showed less dense ferritin labeling compared with those from healthy donors. Quantiative analysis of sialyl residues demonstrated a marked reduction in ferritin labeling of erythrocytes from diabetic patients which was significantly less (p less than 0.01) than that of erythrocytes from healthy donors. This observation supports previous biochemical data demonstrating lower levels of surface membrane negative charge and sialyl residues on erythrocytes from patients with diabetes mellitus.

Abstract
A method involving rapid freezing followed by substitution fixation was developed, using acrolein as a fixative. This was then applied to several cytochemical stainings, and showed well preserved and clear cell structures. Membranes were apparently negatively stained and the ultrastructure of mitochondria, rough endoplasmic reticulum and Golgi apparatus was clearly discernible. The mitochondrial and cytoplasmic matrices were stained rather densely compared with routine chemically fixed preparations, implying a good preservation of matrix substances. Periodic acid-thiocarbohydrazide-silver proteinate staining was applied to the present method. The mucous granules of surface covering epithelial cells indicated fine staining of bipartite structure and the Golgi apparatus of mucous cells showed clear staining differences based on polarity. Postembedding lectin-ferritin and immunocytochemical stainings were applicable to the present preparations and stable stainings of secretory granules were obtained. A low temperature embedding material, Lowicryl K4M, was also examined. The cell preservation of these samples was not as good as those embedded in Epon, but the rough endoplasmic reticulum and Golgi apparatus of chief cells were stained with anti-pepsinogen antibody as were the secretory granules. The present method was also applicable to light microscopy.

Abstract
The fundic gland of the rat stomach was studied using the low-temperature embedding resin Lowicryl K4M and postembedding staining with lectin/colloidal-gold (CG) conjugates. Intense labeling with Ricinus communis agglutinin I was observed not only in mucous-producing cells but also in parietal cells. In contrast, Helix pomatia agglutinin (HPA) only labeled mucous neck cells and intermediate cells between mucous neck cells and chief cells. The other epithelial cells present in the rat fundic gland showed virtually no reaction with this lectin. Our results indicate that HPA might be a marker lectin of mucous neck cells and their derivatives. The combination of embedding in the hydrophilic resin Lowicryl K4M and postembedding staining with lectin-CG conjugates provided satisfactory staining results, and made it possible to visualize the precise distribution of terminal glycoconjugates in intracellular components as well as on the plasma membrane.

Abstract
The localization of lectin-binding sites in the rat gastric mucosa was investigated using horseradish peroxidase-labeled lectin conjugates (Con A, DBA, PNA, RCA-1, SBA, UEA-1, WGA). The glandular epithelium of the cardiac gland was clearly stained with DBA, PNA and SBA. Surface epithelium of the fundic glands was intensely labeled with SBA and UEA-1, but weakly with RCA-1, and WGA. Staining for foveolar cells was intense with SBA and moderate with PNA, while Con A and RCA-1 showed negligible reactivity. Mucous neck cells were intensely stained with SBA, moderately with PNA, weakly with Con A, RCA-1 and WGA, and only, faintly with DBA. Chief cells reacted positively only with WGA. Surface epithelium of the pyloric gland was moderately labeled with DBA, SBA and WGA, and faintly with the other lectins. Glandular epithelial cells, which revealed a similar pattern to that of the surface epithelium, were stained more intensely. The present study provides additional information for elucidating the cellular and regional differences in lectin binding to the rat gastric mucosa.

Abstract
Morphological and histochemical methods revealed cells intermediate between mucous neck cells and chief cells in rat stomach. The secretory granules of mucous neck cells and chief cells were homogeneous. However, some cells resembling mucous neck cells in shape and size yet contained heterogeneous granules. One type of cell contained mucous granules showing a bipartite structure. The inner cores of these granules resembled the granules of mucous neck cells morphologically and after staining by the periodic acid-thiocarbohydrazide-silver proteinate (PA-TCH-SP) procedure and lectin-ferritin methods. The outer layer of these granules, however, resembled the granules of chief cells and failed to stain by these methods. Another type of cell also contained bipartite granules, but these showed a dense cap and lucent matrix. The cap of the granules did not stain with the PA-TCH-SP and lectin methods, but the remaining matrix was reactive. These presumed transitional cells were located in a layer between the mucous neck cells and the chief cells. Immature chief cells with sparse granular reticulum were found near these intermediate cells in some cases. Many similar intermediate type cells were also found in early developmental stages of the gastric mucosa in rat. These results suggest a close relationship between chief cells and mucous neck cells; chief cells may develop from undifferentiated stem cells via mucous neck cells in adult rat stomach.

Abstract
Distribution of glycoconjugates in different areas of the rat kidney was studied by light and electron microscopy using six different horseradish peroxidase-labeled lectins. Glomeruli and brush borders of the proximal tubules reacted differently to these lectins, which indicated differences in the carbohydrate compositions of those regions. The ascending limb of Henle's loop (ALH) had strong binding sites for peanut agglutinin (PNA) and soybean agglutinin (SBA). Dolichos biflorus agglutinin (DBA) did not stain the cells of ALH but did stain those of distal convoluted tubules (DCT). DBA is a good marker for distinguishing ALH from DCT. DBA, PNA, and SBA were also good markers of the collecting duct. Ricinus communis agglutinin (RCA-1) and wheat germ agglutinin (WGA) diffusely stained the various components of different parts of the kidney.

Abstract
The localization of pepsinogen in rat stomachs was investigated by a postembedding immunoferritin method. When the preparations embedded in Epon were used, the secretory granules of chief cells were stained heavily and the granules of mucous neck cells were stained moderately. The secretory granules of cells intermediate between mucous neck cells and chief cells showed a bizonal staining; the electron dense parts were stained heavily and the electron lucent parts were stained moderately. The secretory granules of pyloric gland cells, on the other hand, were labeled faintly. However, the secretory granules of surface mucous cells, foveolar mucous cells, endocrine cells, cardiac mucous cells and cardiac serous cells were not stained by the method. The protein A-gold method showed a similar staining pattern of pepsinogen to that of the immunoferritin method. When the samples embedded in Lowicryl K4M were used to enhance the stainability of pepsinogen, essentially the same staining pattern as that of the samples embedded in Epon was obtained. In addition, the Golgi apparatus and the rough surfaced endoplasmic reticulum were more easily stained.

Abstract
The mucous cells of the rat stomach were stained with lectins by two post-embedding staining methods for electron microscopy. The mucous granules of surface mucous cells and foveolar mucous cells were stained weakly by Ricinus communis agglutinin-ferritin and wheat germ agglutinin-ferritin. The mucous granules of mucous neck cells were stained by concanavalin A-ferritin, Ricinus communis agglutinin-ferritin and wheat germ agglutinin-ferritin. The mucous granules of pyloric gland cells showed an affinity for wheat germ agglutinin-ferritin and concanavalin A-ferritin, while Ricinus-communis agglutinin-ferritin only slightly stained the granules. The granules of mucous neck cells and pyloric gland cells were also stained by the concanavalin A-horseradish peroxidase-colloidal gold method, but the granules of surface and foveolar mucous cells were not stained by this method. Periodic acid oxidation of the sections before the standard concanavalin A-ferritin procedure enhanced the staining of the granules of mucous neck cells and pyloric gland cells slightly. Reduction of the sections after the periodic acid oxidation weakened the staining. Similar results were obtained using the concanavalin A-horseradish peroxidase-colloidal gold method. Though the staining with Ricinus communis agglutinin-ferritin was inhibited by periodic acid oxidation of the sections before staining, the staining with wheat germ agglutinin-ferritin was not inhibited by the oxidation. It is suggested that the paradoxical staining is closely related to the position of the concanavalin A-binding sugar residues in the carbohydrate chains.

Abstract
An endodermal sinus (yolk sac) tumor was successfully transplanted into athymic nude mice. Histologic and ultrastructural investigations revealed that the transplanted tumor had a characteristic appearance with numerous Shiller-Duval bodies, endodermal sinus structures and ultrastructural profiles as previously described in human material. The endodermal sinus tumor and normal human yolk sac have been found to synthesize not only alpha-fetoprotein (AFP), but also other serum proteins, namely, albumin, prealbumin, alpha 1-antitrypsin, and transferrin. Serological study by radioimmunoassay demonstrated AFP, carcinoembryonic antigen (CEA) and human chorionic gonadotropin (HCG) in the sera of the tumor-bearing nude mice and in cyst fluid from the transplanted tumor. Immunohistochemical investigation using the unlabeled antibody peroxidase-antiperoxidase method showed using the unlabeled antibody peroxidase-antiperoxidase method showed that the tumor cells produced CEA, alpha 1-antitrypsin, transferrin, HCG as well as AFP. These immunohistochemical staining properties were correlated with the findings on radioimmunoassay.

Abstract
Postembedding staining of intracellular carbohydrates of rat Brunner's gland cells embedded in Epon and acrylamide was carried out with Ricinus communis agglutinin-ferritin, concanavalin A-ferritin, and wheat germ agglutinin-ferritin conjugates. Th Golgi vacuoles and mucous granules were stained with these conjugates. In each staining, the tissues embedded in acrylamide were stained more strongly than those embedded in Epon. The staining intensity of wheat germ agglutinin-ferritin was the strongest among the three conjugates and the staining intensity of Ricinus communis agglutinin-ferritin was stronger than that of concanavalin A-ferritin in both embedding methods. Free ferritin showed almost no binding to these structures and staining with the conjugates was inhibited by the addition of appropriate competitive sugars to the staining solutions. Osmium-postfixed tissues were not stained well with the conjugates. Washing of the sections with bovine serum albumin solution after staining was an essential step in the present method to reduce the nonspecific adsorption of the conjugates. The present method was very simple and had good reproducibility.
