The orbicularis oris muscle (OOM) is a very important muscle that originate from the second branchial arch and is innervated by the facial nerve. The aim of this study was to elucidate distribution types of two muscle fibers that composing OOM by using enzyme-histochemical examinations and tried to make a basis for a clinical application. The fresh frozen tissues from the superior and inferior portions of the OOM were taken from post mortem 65-year-old Korean male adult. Total five different sagittal sections were used on the midline of the philtrum, the middle portion of lower lip, the mouth corner, and each midlateral side of upper and lower mouth. We used enzyme-histochemical staining such as Periodic Acid-Schiff (PAS), Succinic Dehydrogenase (SDHase), reduced Nicotinamide Adenine Dinucleotide-Tetrazolium Reductase (NADH-TR), Adenosine Triphosphatase (ATPase) in pH 9.4, 4.6 and 4.3, and Modified Gomori Trichrome. There were about 30.24 % type 1 muscle fiber and 65.40 % type 2 muscle fiber in the midline of the philtrum (p < 0.05). Enzyme-histochemical staining is very useful and innovative method to elucidate characteristics of muscle fibers. We expect that chiloplasty and reconstruction of the lip portions for cleft lip patients, based on these results, are better to recovery function and aesthetic. However, we have some problems as an intramuscular variability and the inter-individual variation etc. Therefore we have to make progress these studies continuously to overcome these problems.
This study was conducted to investigate the effect of essential amino acid(EAA) deficient diets on short-term feeding response and the Fos expression in brain area when methionine deficiency diet fed, and thereby to know the mechanism of feed intake regulation. In all trials, experimental diets were formulated with pure amino acid mixture to level of 15% nitrogen. Rats were adapted to a 6-hr single-meal feeding per day(17:00${\sim}$21:00). Feed intake and body weight were monitored every hour after 7-day of feeding of individual EAA deficient diets in Exp. Ⅰ. In Exp. Ⅱ, Fos immuno- histochemistry was determined in various regions of brain to identify the regions that is related to suppressed feed intake following feeding methionine-deficient diet. Fos expression was examined to know the initial sensitive region in the brains of rats at 3h after feeding of the control and methionine deficient diet(-Met). Initial response to EAA deficiency diets was severely depressed in methionine deficiency diet, but the depression was low in threonine deficiency diet. However, the feed intake at 3rd day in rats was depressed in the order of His(71%), Leu(68%), Ile(66%), Thr(63%), Trp(61%), Val(55%), Phe(52%), Met(51%), Lys(44%) and Arg(24%). Fos immunoreaction in neural regions(PPC, amygdala and EPC) of pyrifrom cortex was increased in the -Met group more than in the control diet group, but those in LH, VMH and PVM were similar. Thus, based on these data, the PPC was identified as the initial response area in the -EAA diet.
The histological change of the billary mucosa in clonorchiasis is characterized as adenomatous hyperplasia, and cross-sectioned mucosa looks like intestinal mucosa. In addition to the glandular hyperplasla, the metaplasia of mucin secreting cells is also known. The present study investigated the presence of intestinal secretion from the biliary mucosal cells of rabbits and rats with Clonorchis sinensis infection. The rabbit was infected with 300 and the rat was infected with 100 metacercariae of C. sinensif. A part of the animals were followed up after praziquantel treatment. The rabbit livers were prepared for histochemistry to observe any endocrine secretion and the bile duct mucosa of the mice was processed far the activity of brush border membrane (BBM)-bound enzymes of the small intestine. Immunohistochemistry with the polyclonal antibodies and biotin-streptavidin-peroxidase staining kit showed no positive cells for gastrin and secretin, but a few cells were positive for serotonin. The proliferated billiw mucosa of the mice revealed no activity of dissaccharidases and aminopeptidase. Only alkaline phosphatase activity was found both in the control and the infected. The hyperplastic billary mucosal cells showed no gastrointestinal secretory functions. The serotonin secreting cells may be one of the inflammatory cells.

Objectives: Brain edema is brain swelling that occurs due to the accumulation of excess water in the brain parenchyma. AQP4 and AQP9 are water-channel proteins expressed strongly in the brain and control water fluxes into and out of the brain parenchyma. This study was conducted to evaluate effect of Hwangnyeonhaedok-tang on brain edema and intracerebral hemorrhage. Methods: Intracerebral hemorrhage was induced by intrastriatal injection of type IV collagenase(0.23 U/${\mu}l$, 0.1 ${\mu}l$/min) into Sprague-Dawley rat brains. Hwangnyeonhaedok-tang water extract(1,000 mg/kg) was administered orally three times every 20 hours from 4 hours after ICH operation. Then hematoma volume, brain edema percentage, and water content of brain tissue were measured. Immuno-histochemistry was performed for AQP4 and AQP9 expressions in the brain sections and area % of immuno-labeling was analyzed with image analyzing system. Results: 1. Water extract of Hwangnyeonhaedok-tang reduced hematoma volume of ICH induced rat. 2. Water extract of Hwangnyeonhaedok-tang reduced MPO positive neutrophils in the perihematoma of the ICH induced rat. 3. Water extract of Hwangnyeonhaedok-tang reduced brain edema percentage and water content of brain tissue of ICH induced rat. 4. Water extract of Hwangnyeonhaedok-tang reduced AQP4 immuno-positive cells in the perihematoma of the ICH induced rat. 5. Water extract of Hwangnyeonhaedok-tang reduced AQP9 immuno-positive cells in the perihematoma of the ICH induced rat. Conclusions: These results suggest that Hwangnyeonhaedok-tang decreases intracerebral hemorrhage and brain edema by means of downregulating AQP4 and AQP9 expressions in the brain.
Culture of osteoblast is extremely valuable in analyzing biological features that are specific to bone. ENA-A, ENA actimineral resource A, is a seaweed origin alkaline water. To investigate the bioactivity of ENA which act on bone metabolism, we studied the effects of a ENA on the activity of osteoblast MC3T3-E1 cells. ENA (1, 2, 4%) dose-dependently increased survival (p<0.05) and alkaline phosphatase activity (p<0.05) on MC3T3-E1 cell. And examined histochemistry and nodule formation according to the time course. To determine the expression patterns of bone-related proteins during the MC3T3-E1 osteoblast-like cell differentiation by using RT-PCR. This study suggest that ENA may promote the function of osteoblastic cells and play an important role in bone formation.
The wound healing is very complex biological processing including inflammatory, reepithelialization and matrix construction. According to the biological systematic category, the ability of the healing is very different. Generally healing ability of the lower animal group has been known more excellent compared to its higher group. Therefore, lower animals have been used as the experimental model to explore the mechanism of the wound healing or repair. To verify histochemical characteristics of the wound healing, we have used skin of the frog (Bombina orientalis) as known common amphibian. At day 1, 10, and 16, the mucous substance was very actively synthesized and strong positive by PAS and Alcian blue (pH 2.5). Day 10 after wounding, margin of the wound was gradually strong positive by PTAH staining for detection of collagen synthesis. At 3 to 6 hour and day 23 to 27, we have found the cell division was active through the MG-P staining, in which the concentration and division of DNA in nucleus was green to deep blue color.
The present study was carried out to investigate the effect of microwave fixation in comparison with that of chemical fixation in preparing the microscopic samples. The microwave fixator was equipped with infrared-temperature sensor, and that was designed to compensate air temperature in the microwave fixator. In the microwave fixation, rat tongue was well preserved in terms of muscular fasciculus and pancreas stained by Feulgen reagents showed clear reaction products in the nucleus. Reaction products by PAS method in duodenal villi appeared specifically at the goblet cells. In electron microscopy, pancreatic cellular components such as secretory granules and collagen bundles were well preserved in both fixations. In aspect of histochemical reaction and electron microscopy, high quality was due to the protein content of microwave fixed specimen. The microwave fixation method saved total duration engaging microscopic preparation.

Purpose : This study was carried out to investigate the effects of Gamigwichulpajing-Tang(GGT) on the development of experimentally-induced endometriosis in rats. Materials and Methods : Endometriosis was induced in rats by auotransplanting uterine tissue to the peritoneum and devided them into three groups: (1) sham-operated group(n=8), (2) surgically induced endometriosis and untreated control group(n=8), (3)surgically induced endometriosis and GGT treated group. GGT(700mg/head) was orally administrated for 15days after operation. Then we measured the body weight, the volumes of endometriotic implants, the weight of uterus and ovary, and investigated the content of cytokines(MCP-1, $TNF-{\alpha}$, $IL-l{\beta}$) in serum and ascites. Histopathology, immunohistochemistry for COX-2, and histochemistry for mast cell in transplanted uterine tissue were performed. Results :- The $volume(mm^3)$ of endometriotic implants in GGT-treated group$(53.50\;{\pm}18.63)$ was significantly decreased(p<<0.01) compared with control group$(404.50{\pm}317.68)$. - The content(pg/ml) of MCP-1 in ascites in GGT-treated group$(4265{\pm}108)$ was significantly decreased(p<<0.001) compared with control group$(8632{\pm}1245)$. - The content(pg/ml) of $TNF-{\alpha}$ in serum in GGT-treated group$(64.5{\pm}21.6)$ was significantly decreased(p<<0.05) compared with control group$(147.1{\pm}78.2)$. - The content(pg/ml)- of $TNF-{\alpha}$ in ascites in GGT-treated group$(738.3{\pm}502.4)$ was significantly decreased(p<<0.05) compared with control group$(1245.2{\pm}362.2)$. - The percentage(%) of positive epithelial layers for COX-2 in GGT-treated group$(22.9{\pm}9.3)$ was significantly decreased(p<<0.001) compared with control group$(50.2{\pm}8.2)$. - The number of mast cells in adjacent tissue of transplanted uterine tissue in GGT-treated group$(61.4{\pm}13.9)$ was significantly decreased(p<<0.001) compared with control group$(109.3{\pm}30.2)$. - The number of mast cells in stroma of transplanted uterine tissue in GGT-treated group$(9.4{\pm}2.7)$ was significantly decreased(p<<0.001) compared with control group$(26.0{\pm}7.7)$. - Histopathologically, proliferation of endomeuiotic epithelia and stroma, and infiltration of inflammatory cells in transplanted uterine tissue of GGT-treated group were weakly observed than those of control group. Conclusion :On the basis of these results, we concluded that Gamigwichulpajing-Tang have inhibiting effects on the development of transplanted uterine tissue. And these effects may be related with decreased Production of MCP-1 and $TNF-{\alpha}$, decreased expression of COX-2, and decreased infiltration of mast cells by administration of Gamigwichulpajing-Tang.
Purpose : This study was performed to investigate the effects of Sobokchukeo- Tang(SCT) on the experimentally-induced endometriosis in rats. Materials and Methods : Endometriosis was induced via the surgical autotransplantation technique in rats. A laparotomy was performed and a $4\;{\times}\;4\;mm$ of the right uterine horn was resected incised and sutured to the peritoneum. And the animals divided into control(n=8) and SCT-treated group(n=8). SCT(1,000 mg/head) was administered orally for 15 days after operation. The weights(body, left uterus, and ovaries) and concentrations of cytokines(MCP-1,$TNF-{\alpha}$, $IL-l{\beta}$) were measured. Histopathology, immunohistochemistry for COX-2, and histochemistry for mast cells of the transplanted uterine tissues were performed. Results : - The $volume(mm^3)$ of transplanted uterine tissues of SCT-treated group$(92.88{\pm}41.89)$ was significantly(p<<0.01) decreased than the control group $(404.50{\pm}317.68)$. The concentration(pg/ml) of MCP-1 in ascites of SCT-treated group$(5,256{\pm}1,209)$ was significantly(p<<0.001) decreased than the control group$(8,632{\pm}1,245)$. - The concentration(pg/ml) of $TNF-{\alpha}$ in ascites of SCT-treated group$(521.8{\pm}306.1)$ was significantly(p<<0.01) decreased than the control group$(1,245.2{\pm}362.2)$. - The percentage of COX-2 positive epithelial layer in transplanted uterine tissues of SCT-treated group$(25.0{\pm}7.3)$ was significantly(p<<0.001) decreased than the control group$(50.2{\pm}8.2)$. - The number of mast cells in the stroma of transplanted uterine tissues of SCT-treated group$(16.5{\pm}6.8)$ was significantly(p<<0.05) decreased than the control group$(26.0{\pm}7.7)$. - The number of mast cells in the periphery of transplanted uterine tissues of control group$(71.3{\pm}18.5)$ was significantly(p<<0.01) decreased than the control group$(109.3{\pm}30.2)$. - Proliferation of epithelia, infiltration of inflammatory cells, and microanglogenesis in transplanted uterine tissues of treated group were weakly observed than the control group. Conclusion : From the above results, Sobokchukeo-Tang(SCT) has an inhibitory effect on the development of transplanted uterine tissue in rats and it is related to the decreased concentration of MCP-1 and $TNF-{\alpha}$, and decreased expression of COX-2, and decreased infiltration of mast cells by administration of Sobokchukeo-Tang.
