Objective: To find out the anticancer effect of Indigofera aspalathoides (I. aspalathoides) on 20-methylcholanthrene induced fibrosarcoma in rats. Methods:Fibrosarcoma was induced in Wistar strain male albino rats by 20-methylcholanthrene. Intraperitoneous (i.p.) administration of 250 mg/kg body weight/day of aqueous extract of I. aspalathoides for 30 d effectively suppressed chemically induced tumors. Parameters such as body weight, liver and kidney weight, tumor weight, mean survival time, behavioral changes, blood glucose, blood glycogen and marker enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), acid phosphatase (ACP) and 5'-nucleiotidase (5'-NT) in serum, liver and kidney and lipid profiles such as total cholesterol, phospholipids, free fatty acids in liver and kidney of control and experimental animals were studied. Results:Fibrosarcoma bearing animals were ferocious and anxious. The mean survival time was found to increase after the treatment. The body weights were significantly decreased (P<0.001) in group II fibrosarcoma animals which steadily increased after the treatment with I. aspalathoides. The liver and kidney weights were significantly increased whereas the tumor weights decreased as compared to the weights in untreated fibrosarcoma bearing rats. The blood glucose and the liver and kidney glycogen levels were found to decrease significantly (P<0.001) in group II animals. Elevated activities of marker enzymes were observed in serum, liver and kidney of fibrosarcoma bearing Group II animals which were normalize after I. aspalathoides treatment. In the liver and kidney of Group II animals the total cholesterol increased whereas the phospholipids and free fatty acid levels decreased (P<0.001) which were normalized after treatment. Conclusions:The treatment by I. aspalathoides on fibrosarcoma bearing rats has improved the levels of various parameters indicating its antiproliferative and anticancer activity.

Objective: The present study was aimed to scrutinize the anticancer consequence of kaempferol against aflatoxin B1 induced hepatocarcinogenesis. Epidemiological studies of the incidence of liver cancer in the population, where dietary aflatoxin exposure is high, have provided much circumstantial evidence for the development of aflatoxin B1 induced primary liver cancer in humans. Methods:In the present investigation, aflatoxin B1 (2 mg/kg body weight i.p) was used as a hepatocarcinogen to induce hepatocellular carcinoma in experimental animals. Results: In the present analysis, on treatment with bioflavonoid kaempferol (100 mg/kg body weight p.o) the nucleic acids levels were brought back to normal and also the altered levels of biological enzymes such as membrane bound ATPase, carbohydrate metabolizing enzymes and mitochondrial TCA cycle enzymes levels (P<0.01).Conclusions:Membrane bound ATPase, carbohydrate metabolizing enzymes and mitochondrial TCA cycle enzymes were modulated by kaempferol evaluated on aflatoxin B1 induced primary liver carcinogenesis.

INTRODUCTIONIndications for flexible intramedullary nailing, as well as advancements in this technique, have evolved considerably with time and individual experience. We implemented and studied a simplified version of the technique. Functional outcome, osseous union and related issues are discussed.

METHODSA total of 15 patients aged 5-15 years with diaphyseal femur fracture were selected for the study. The patients' fractures were stabilised with flexible intramedullary nails through lateral entry alone. After a minimum follow-up period of six months, the outcomes were analysed.

RESULTSThe mean patient age was 8.7 years, and patients were followed up for a mean duration of 12 months. Radiological union was achieved within a mean duration of 7.5 weeks. The outcomes were excellent in most of the cases.

CONCLUSIONAdequate fixation was achieved through the use of flexible nails as intramedullary splints. The results were comparable to that of the original technique. Further study is obligatory.

BACKGROUND/AIMS: Although carcinoid tumors usually have good prognosis, early and specific diagnosis is important. Computed tomography and magnetic resonance imaging do not provide findings that are specific for carcinoids, and somatostatin receptor scintigraphy suffers from low spatial resolution. 18-Fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has limited sensitivity for carcinoids due to low uptake of the marker. A PET/CT system that uses the somatostatin receptor-based PET tracer 1,4,7,10-tetraazacyclododecane-N(I),N(II),N(III),N(IIII)-tetraacetic acid (D)-Phe(1)-thy(3)-octreotide ((68)Ga-DOTATOC) has also been used in the evaluation of carcinoids, although information regarding its use for the detection of primary pulmonary carcinoids is limited. Thus, we investigated the value of (68)Ga-DOTATOC PET/CT for the diagnosis of primary pulmonary carcinoid tumors. METHODS: This was a retrospective analysis of patients with primary pulmonary tumors who underwent (68)Ga-DOTATOC PET/CT. All the patients had a histopathologic diagnosis of carcinoid. The rate of detection of primary pulmonary carcinoid tumors using (68)Ga-DOTATOC PET/CT was assessed. RESULTS: Twenty patients were diagnosed as having carcinoid, and 19 tumors showed significant uptake on (68)Ga-DOTATOC (detection rate, 95%). The maximal standardized uptake value (SUV(max)) ranged from 1.1 to 66, with a median value of 21.6. In one patient, (68)Ga-DOTATOC PET/CT revealed additional lesions. CONCLUSIONS: Our results demonstrate that (68)Ga-DOTATOC PET/CT is useful in the evaluation of primary pulmonary carcinoids and should be included in the diagnostic work-up of these patients.

A natural prodrug is a chemical compound or substance obtained from plants, microorganism, animal and marine sources. Natural products are small molecule source for Food and Drug Administration approved drugs and major sources for drug discovery. Most of the drugs for different ailment diseases undergo first pass metabolism, resulting in drug inactivation and the generation of toxic metabolites in body. Enormous numbers of prodrugs naturally present in plants, microorganism, animal and marine sources and those prodrugs undergoes chemical reaction to form non-toxic compounds. This review summarizes the list of prodrugs naturally present in the natural product.

PURPOSE: The fractures of anterior mandible are subject to severe torsional forces due to muscles acting in opposite directions. 3D miniplate has been suggested as a good alternative by some researchers. However, finite element model (FEM) studies indicate that labio-inferior positioning of two miniplates perpendicular to each other offers better stability as compared to labial positioning. This study aims at combining the advantages of a single 3D miniplate and labio-inferior positioning of two conventional miniplates, which was assessed by finite element analysis along with a pilot clinical trial. METHODS: Two FEM models were created using CT data of a 24-year-old patient with Angle class I occlusion: control model with labial plating and study model with labio-inferior plating. The models were processed with MIMICS® (materialise, Leuven, Belgium), CATIA® (Dassault Systemes) and finite element analysis softwares. Parameters adopted for analysis were (1) displacement (mm) of fracture fragments during each screw fixation, (2) lingual splay and post fixation stability of fracture fragments with masticatory load, and (3) stress distribution (MPa) across fracture fragments. Moreover, a pilot clinical trial including five patients with anterior mandible fracture was conducted. The fractures were managed by intraoral open reduction and 3D miniplate fixation in labio-inferior position. Intraoperative interfragmentary gap, post fixation lingual splay and radiographic fracture union and complications were assessed clinically. RESULTS: Labio-inferior plating demonstrated less displacement (mm) of fracture fragments during screw fixation (0.059 vs. 0.079) as well as after application of masticatory load (1.805 vs. 1.860). Negligible lingual splay and less stress distribution (MPa) across fracture fragments (1.860 vs. 1.847) were appreciated in the study group as compared to control group. Clinical trial support the favorable outcome related to intraoperative and postoperative assessment parameters. CONCLUSION FEM analysis and clinical trial reveal better results with labio-inferior positioning of 3D miniplate when compared to labial positioning.
