The current density in copper electroplating is directly related with the productivity; then, to increase the productivity, an increase in current density is required. This study is based on an analysis of changes in surface characteristics and mechanical properties by applying the addition of Alcian Blue (AB, C₅₆H₆₈Cl₄CuN₁₆S₄). The amount of Alcian Blue in the electrolytes is changed from 0 to 100 ppm. When Alcian Blue is added at 20 ppm, a seed layer is formed homogeneously on the surface at the initial stage of nucleation. However, crystals electroplated in electrolytes with more than 40 ppm of Alcian Blue are observed to have growth in the vertical direction on the surface and the shapes are like pyramids. This tendency of initial nucleation formation causes protrusions when the thickness of copper foil is 12 ㎛. Thereafter, a lot of extrusions are observed on the group of 100 ppm Alcian Blue. Tensile strength of groups with added Alcian Blue increased by more than 140% compare to no-addition group, but elongation is reduced. These results are due to the decrease of crystal size and changes of prior crystal growth plane from (111) and (200) to (220) due to Alcian Blue.

Excess secretion of goblet cell stimulated by inhalation anesthetics have side effects during operation or postoperative care. Mucosubstances, which are almost secreted by goblet cells in the epithelium of the respiratory tract, are secreted by a direct irritation of inhalation anesthetics. This study was carried out to compare the differences of mucus secretion on lower respiratory tract stimulated by ethyl ether, halothane and isoflurane. Total of 24 rabbits were used as experimental animals. The trachea and the 1st bronchi were fixed in 10% neutral buffered formalin. After embedding in paraffin, the specimens were sectioned to a thickness of 6 ${\mu}{\textrm}{m}$, and PAS-H, Alcian blue pH 2.5 and Alcian blue pH 1.0 stains were performed for the observation of the composition and the quantity of the mucus. The results were as follows; Ethyl ether and isoflurane irritated the mucous membrane of the respiratory tract. Ethyl ether irritated more than isoflurane. Halothane irritated the mucous membrane, but its effect was minimal and had little influences during operation. In the specimens stained with PAS-H, Alcian blue pH 2.5 and Alcian blue pH 1.0, the mucosubstance lining the cilia and in the goblet cells of the trachea and 1st bronchi were the strongly PAS-H reactive mucosubstances, moderately Alcian blue pH 2.5 and Alcian blue pH 1.0. The PAS-H reactive mucosubstance were polysaccharides, neutral mucopolysaccharides, mucoproteins, glycoproteins and glycolipids. Trachea was easily affected than bronchi by inhalation anesthetics. Consequently, it is suggested that because halothane does not irritates respiratory mucosal secretion, its application may be efficient to the depressed respiratory system.

Polysaccharide contents in Panax ginseng roots were evaluated by a spectrophotometry, utilizing the complex formation of ginseng polysaccharide with alcian blue dye in 50 mM ammonium biphos-phate, pH 4.2. The polysaccharide content in red ginseng was about three times higher than that in fresh ginseng when both were extracted with water, and increased about two times when red ginseng was extracted with an alkaline solution. The determination of polysaccharide in various parts of ginseng revealed that main roots contained the component more than fine roots. Fresh ginseng sections stained by the dye showed polysaccharide mainly was found in cortex and combium but not in epidermis.

The author observed histochemically the nature of the calcified tissue in the rabbit dental pulp, induced by pulpal injection of potassium permanganate. The pulp of rabbit mandibular incisors were exposed and enlarged by a dental hand reamer. The exposed pulps were injected with 0.05ml of 20mM solution of potassium permanganate dissolved in Ringer's solution in experimental tooth. Also the control tooth received a pulpal injection of 0.05ml of Ringer's solution. After pulpal injection, the tooth was plugged with a gutta-percha root canal point. The staining techniques were hematoxylin-eosin stain, van Gieson stain, PAS reaction, toluidine blue stain, alcian blue-hematoxylin stain and colloidal iron-picric acid stain. The results were as follows: 1. The pulp on experimental tooth showed osteodentin-like calcified tissue. Also, in some areas, false denticle-like substance were observed. 2. The central portion of the calcified matrix showed metachromasia in toluidine blue stain had strong staining capacity in alcian blue stain. 3. The peripheral portion of the calcified tissue revealed marked van Gieson positive reaction for collagen. But their staining ability in alcian blue was slight and metachromasia was not appeared.

Background : cis-Diamminedichloroplatinum(Ⅱ)(cis-platin) has been exhibited similar to bifunctional alkylating agents in the cell and known as an effective anticancer drug. Although this agent is very beneficial to the cancer patients, it may also damage to the normal cell. Many side effects were developed. Objectives : This experiments was undertaken to pursue the effect of cis-Platin on the mucous variation of the trachea. Materials and Methods : The male of Sprague-Dawley strain were used as and experimental animals. The experimental animals were killed at 1, 3 days and 1, 2 and 3 weeks after the third injection of cis-Platin was administered 1.5mg/kg to intraperitoneal injection at once a week for three weeks. The trachea was fixed to neutral formaline and stained with alcian blue(pH 1.0)-PAS, alcian blue(pH 2.5)-PAS double stains and these preparation observed with light microscope. Results : 1. In the trachea stained with alcian blue(pH 2.5)-PAS double stain, the epithelial cells were constricted in the 1 week, In the 1st day, 3rd day and 1st week, acidic mucopolysaccharide was increased but in the 2nd week, neutral mucopolysaccharide was increase. 2. In the trachea stained with alcian blue(pH 1.0)-PAS double stain, the 1st and 3rd day exhibited sulfa mucopolysaccharide with moderately or weakly positive reaction. In the 1st week the sulfa mucopolysaccharide with strongly positive reaction was increased. In the 2nd and 3rd week, the sulfa mucopolysaccharide with weakly positive and non-sulfa or neutral mucopolsaccharide with negative reaction were modified. Conclusion : It is consequently suggested that cis-Platin induces reversible toxic damage to tracheal cells including goblet cell.

The effects of isoproterenol, a sympathomimetic amine, on the mast cells in the oral mucosa were cytochemically studied in twenty four healthy male albino rats weighing approximately 100gm. seven groups of three each were injected intraperitoneally, as a single dose of 8mg/100gm. body wt., (dissolved in 0.9% saline 0.2㎖). Each groups were sacrificed following ether anesthesia at he time indicated, 1. 2. 3. 5. 7. 10. 14days after only a single injection. One normal group is not administered with any substances. The sections of oral mucosa were stained with 0.005% toluidine blue (Mowry's method) and alcian blue (pH 2.5). We found that isoproterenol made an initial decrease in the metachromasia and alcian blue affinity, and the number of mast cell, followed by an subsequent return to normal.
