Capillary malformation (CM), or "port-wine stain," is a common cutaneous vascular anomaly that initially appears as a red macular stain that darkens over years. CM also occurs in several combined vascular anomalies that exhibit hypertrophy, such as Sturge-Weber syndrome, Klippel-Trenaunay syndrome, and Parkes Weber syndrome. Occasional familial segregation of CM suggests that there is genetic s...

Amyloidosis is characterized by the deposition of misfolded protein in various organs. The diagnosis of amyloidosis is based on the detection of amyloid deposits by Congo red stain under polarized microscopy. This study was done to investigate C4d deposition in amyloidosis and to determine whether C4d staining can be used as a new diagnostic tool for amyloidosis. This retrospective study includ...

I N THE COURSE of cunrrent investigations on leukocyte granules, the questioni arose as to w’hether the group responsible for the stable sudanophilia might be a primary amine. It is well known that primary amines are differentially destroyed by nitrous acid,’3 thus: RNH2 + HNO2-ROH + H2O + N2. In testing this hypothesis we used both Vans Slyke’s reagent* arid molar solutionis of sodium nitrite ...

I N 1955 Schmid et al.1 noted the presence of intranuclear heme inclusions in the fluorescing normoblastic nuclei of several patients with ( congenital) erythropoietic porphyria. With a routine Romanovsky stain they were able to demonstrate incompletely stained areas in the nuclei. In addition, these inclusions stained positively with benzidine2 and showed a strong absorption at 400 ITIJL, clea...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 53-year-old man presented with a history of weight loss of 10 kg over 3 months. A peripheral blood count indicated a leukocyte count of 49.0×10 3 /L and 80% segmented neutrophils. The neutrophils showed toxic changes and appeared in hypersegmented forms. ...

Periodontium is a complex organ composed of mineralized epithelial and connective tissue. Dexamethasone could stimulate proliferation of osteoblast and fibroblasts. This study aimed to assess the osteogenic effect of dexamethasone on periodental ligament (PDL) stem cells. PDL stem cells were collected from periodontal ligament tissue of root of extracted premolar of young and healthy people. Th...

BACKGROUND Liposuction is a procedure to reduce the volume of subcutaneous fat by physical force. Intracellular storage fat is composed of triglyceride, whereas circulating fat particles exist as cholesterol or triglycerol bound to carrier proteins. It is unavoidable that the storage form of fat particles enters the circulation system after these particles are physiologically destroyed. To date...
