Localized fibrous tumor of the pleura is a rare condition. Most follow a benign course and they are round as an incidental finding during routine chest X-ray. A small proportion of these tumors are malignant and have characteristic clinical and histopathological features. In this paper, we report three cases of localized fibrous tumors of the pleura, one malignant associated with asymptomatic hypoglycemia, the others benign. In a malignant case, the tumor was reseated through thoracotomy and the hypoglycemia was relieved immediately. In two benign cases, tumors on small pedicles were resected using video-assisted thoracic surgical technique.

The present study is aimed at finding the effect of B-20 drops, a homoeopathic formulation, in streptozotocin (STZ) induced diabetic rats. B-20 drops comprises of the constituents derived from plants and other natural sources, and are generally prescribed by the homoeopathic physician, in cases of hyperglycemia and diabetes. The elevated levels of fasting blood glucose and pancreatic lipid peroxides observed in rats treated with STZ were significantly reduced by the treatment of B-20 drops. The reduced liver glycogen contents were also brought back to near normal level by B-20 drops treatment in STZ diabetic rats. STZ induced histopathological changes in pancreas and liver was also partially reversed by B-20 drops. The findings indicate that B-20 drops help in improving the glycogen stores in the liver and prevents STZ induced damage through free radicals by decreasing the pancreatic lipid peroxides levels.

The present study was conducted to investigate the potential subacute toxicity of CJ-10882 by a 4-week repeated oral dose in dogs. The test article was administered once dally by gavage to dogs at dose levels of 0, 2, 10, and 50 mg/kg/day for 4 weeks. During the test period, clinical signs, mortality, body weights, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross finding, organ weight, and histopathology were evaluated. Several clinical sign were observed in treated dogs at 50 mg/kg, including salivation and vomiting. Increase in the serum level of ALT and albumin observed in the female 50 mg/kg group was considered as a toxic effect related to the test article since the histopathological change in Liver was accompanied. There were no treatment-related effects on mortality, food and water consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, necropsy findings and organ weights in any treatment group. Based on these results, target organ was not observed and the no-observed-adverse-effect level (NOAEL) was 10 mg/kg/day and the absolute toxic dose was 50 mg/kg for both male and female dogs.

Cysticercosis is not likely to be the first diagnosis the otologist has in the head and neck area. The fact that this disease may present a diagnostic and therapeutic problem is illustrated by one case, appearing in the face of right side. The local finding of a soft nontender mass, the typical calcifications in the soft tissues visible on roentgenograms, and the histopathological findings are described and illustrated. Attention is drawn to the fact that cerebral cysticercosis, which is a very grave disease, may cause tinnitus, nystagmus, and hearing disturbances. Recently, the authors have experienced a case of cysticercosis on the face in a 24-year-old male patient. We present this case with a brief review of the literatures.

Micronutrients in food have been found to have chemopreventive effects, supporting the conclusions from epidemiologie studies that consumption of fresh fruits and vegetables reduces cancer risk. The present study was carried out to evaluate the role of querctin (Q) and sodium gluconate (GNA) supplementation separately or in combination in ameliorating promotion of colon tumor development by dimethyl-hydrazine (DMH) in mice. Histopathological observation of colons in mice treated with DMH showed goblet cell dysplasia with inflammatory cell infiltration. This pathological finding was associated with significant alteration in oxidative stress markers in colon tissues and carcinoembryonic antigen (CEA) levels in plasma. Mice co-treated with GNA and Q showed mild changes of absorptive and goblet cells and inflammatory cell infiltration in lamina properia, with improvement in oxidative stress markers. In conclusion, findings of the present study indicate significant roles for reactive oxygen species (ROS) in pathogenesis of DMH-induced colon toxicity and initiation of colon cancer. Also, they suggest that Q, GNA or the combination of both have a positive beneficial effect against DMH induced colonic cancer induction in mice.

Progressive multifocal leukoencephalopathy(PML) is a fatal demyelinating disease that occurs in immunocompromised hosts. We report a case of PML that developed in patient with T cell lymphoma of head and neck. During chemotherapy for lymphoma, she was confused and had memory impairment. A magnetic resonance imaging of the brain revealed confluent signal change at white matter of the frontal lobe, insula, and anterior limb and genu of internal capsule. The lesion was confirmed with brain biopsy and the histopathological finding was compatible with PML.

Helicobacter pylori infection is acquired mainly during childhood and causes various diseases such as gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and iron deficiency anemia. Although H. pylori infection in children differs from adults in many ways, this is often overlooked in clinical practice. Unlike adults, nodular gastritis may be a pathognomonic endoscopic finding of childhood H. pylori infection. Histopathological findings of gastric tissues are also different in children due to predominance of lymphocytes and plasma cells and the formation of gastric MALT. Although endoscopy is recommended for the initial diagnosis of H. pylori infection, several non-invasive diagnostic tests such as the urea breath test (UBT) and the H. pylori stool antigen test (HpSA) are available and well validated even in children. According to recent data, both the $^{13}C$-UBT and HpSA using enzyme-linked immunosorbent assay are reliable non-invasive tests to determine H. pylori status after eradication therapy, although children younger than 6 years are known to have high false positives. When invasive or noninvasive tests are applied to children to detect H. pylori infection, it should be noted that there are differences between children and adults in diagnosing H. pylori infection.

Developmental pulmonary abnormalities are known as rare condition. diagnosis was made at autopsy in the early cases reported, however, as diagnostic aids such as X-ray, bronchography, bronchoscopy and exploratory thoracotomy have come into use, the condition is being discovered more often recently in living persons, and it appears to occur with sufficient frequency to merit consideration in the differential diagnosis of certain chest conditions. According to Schneider and Boyden there are three main types of this abnormality: [1] Agenesis, in which there is complete absence of one or both lungs; there is no trace of bronchial or vascular supply or of parenchymal tissue. [2] Aplasia, in which there is suppression of all but a rudimentary bronchus which ends in a blind pouch; there are no vessels or parenchyma. [3] Hypoplasia, in which the bronchus is fully formed but is reduced in size and ends in a _ flesh structure which usually lies within the mediastinum. Rudimentary pulmonary parenchyma may be present around the bronchial stump and often is the site of cystic malformation. We experienced one case of hypoplastic lung with cystic malformation which was originated from a small aberrant rudimentary bronchus, and the rudimentary bronchus was branched from the right side of tracheal end. The diagnosis was finally confirmed by the histopathological finding. Now, we report this case with a brief review of literatures.

Kimura's disease is a chronic inflammatory disease with unknown etiology. The most common clinical presentation of Kimura's disease is non-tender unilateral mass in the head and neck area, but bilateral involvement has rarely been reported. Histopathological confirmation should be taken for the diagnosis. Various management options are available, including surgical excision, steroid therapy, and radiotherapy. We report a male patient diagnosed as Kimura's disease involving bilateral retro-auricular region. Simultaneous bilateral neck involvement is an extremely rare finding. For cosmetic reasons, the patient was treated surgically, with satisfactory postoperative results. When evaluating patients with mass lesion in bilateral parotid/retro-auricular area, Kimura's disease should be considered as differential diagnosis.

Silymarin is a flavonoid complex extracted from the Silybum marianum plant with a wide range of pharmacological and biochemical effects. In the present study, the immunomodulatory effects of silymarin were investigated in BALB/c mice. Silymarin was administered daily by intraperitoneal injection at doses of 50, 100 and 150 mg/kg for 14 consecutive days. Following the exposure, host hematological parameters, spleen cellularity and histopathological examination, as well as delayed-type hypersensitivity (DTH) responses, hemagglutination titers (HA), splenocyte cytokine production and lymphocyte proliferation assay were studied in all of the test groups of animals. The results showed that the low dose of silymarin (50 mg/kg) could stimulate both cellular and humoral immune functions in the treated hosts. In addition, silymarin at 100 mg/kg appeared to impact on DTH responses and lymphoproliferation. Based on the finding here, it would seem that silymarin has efficient immunostimulant properties. As a recommendation, the application of silymarin along with acupuncture technique (herbal acupuncture) can be thought as a good plan to modulate and enhance the immune system for the management of several immunodeficiency disorders. However, further studies are required to demonstrate this hypothesis.
