OBJECTIVE
This study sought to investigate the effect of caries, in association with physiological root resorption, on the pulpal status of human primary molars.
METHODS
Fifty-three mandibular primary molars were obtained from children requiring extractions under general anaesthesia. Following
The tertiary and quaternary structure of the lectin I from Ulex europaeus (UE-I) has been determined to 2.2 A resolution. UE-I is a dimeric metalloglycoprotein that binds the H-type 2 human blood group determinant [alpha-L-Fucalpha(1-->2)-beta-D-Galbeta(1-->4)-beta-D-Glc NAcalpha-]. Nine changes
An embryonal carcinoma was diagnosed in the abdominal cavity of a 55-day-old male calf. Macroscopically, a large volume of ascitic fluid was observed along with white to yellowish-white masses of various sizes densely located on the abdominal wall and the surface of abdominal organs. There was an
OBJECTIVE
To investigate the presence of vanilloid receptor 1 (TRPV1) in human dental pulp and to correlate any expression with caries and pain.
METHODS
Permanent mandibular first molars were collected and categorized as intact or grossly carious. Grossly carious teeth were further categorized as
The present investigation was undertaken to assess the binding characteristics of eight different lectins to normal oral mucosa (11 cases), leukoplakia with varying degrees of dysplasia (five cases), and oral mucosal squamous cell carcinoma (12 cases) by the use of biotinylated lectins and avidin
The carbohydrate moieties of microfilariae (Mf) and infective larvae (L3) have been investigated by lectin-binding technique. Mf derived from three sources, namely, uteri (in utero), released in vitro from adults and from blood of rodents infected with Litomosoides carinii were examined by using
In order to shed more light on the controversial tissue histogenesis of the stromal cells (SC), light microscopic, immunohistochemical and electron microscopic studies were performed on surgical specimens of hemangioblastomas (36, 26 and 7 cases, respectively). SC were immunoreactive for vimentin,
Epithelioid hemangioendothelioma (EH) is a recently described vascular neoplasm of borderline or intermediate malignant potential. This tumor arises from medium- to large-sized vessels, primarily involves the soft tissues of the extremities as well as the liver and lung, and rarely occurs in the
Sinonasal hemangiopericytomas are rare, occasionally misdiagnosed neoplasms that have often been considered distinct from hemangiopericytomas of other sites. Eleven cases were studied. Nine arose from the nasal cavity and two from the paranasal sinuses. The patients' mean age was 58 years. In nine
Acute phase of stroke is the focus of most experimental and clinical studies on cerebral ischaemia. The scarcity of data on remote changes led us to examine the morphological pictures of brains after ischaemic insults. We paid special attention to the white matter capillaries. We microscopically
Litomosoides chagasfilhoi is a filariid nematode parasite of the abdominal cavity of the wild rodent Akodon cursor (Winge, 1887), that has been described and used in Brazil as a new model for human filariasis. The fine structure of the intestine of this nematode was analyzed based on observations
Eight tumors diagnosed as solitary fibrous tumor (SFT) of the oral cavity were studied. Histologic spectrum was entirely comparable with the extrapleural SFT of other sites. One tumor had glomus tumor-like foci. Immunohistochemical results confirmed most of the previous observations, indicating
OBJECTIVE
To evaluate angiogenesis dependent characteristics of carcinoma proliferation, metastasis and to found if there is tumor vascularity architecture defect.
METHODS
36 rabbits were random divided into 2 groups: Experimental group: 18 rabbits liver were implanted with VX2 tumor by surgery
Adrenal pseudocysts are cystic lesions arising within the adrenal gland surrounded by a fibrous tissue wall devoid of a recognizable lining layer. This study comprised eight adrenal pseudocysts surgically excised at the Massachusetts General Hospital. The median age of the patients was 41 years.
Malignant endothelial neoplasms involving the serous membranes are rare, and only a few cases have been documented. We report 14 patients with epithelioid hemangioendothelioma (EHE) or epithelioid angiosarcoma (EA) diffusely involving the pleural, peritoneal, or pericardial cavities, resulting in a
