Heavy metal exposure in animals can lead to profound effect on growth, development and biochemical constituents. It is necessary that the heavy metal toxicity be well documented and adequate precaution should be taken in mother and fetus to decrease its detrimental effects. An experimental study was performed with viviparous animal Heterometrousfulvipes to access the cumulative effect of chronic heavy metals exposure on lipid metabolism.Chronic heavy metal exposure resulted in decrease in biochemical constituents of lipids, with decrease in hepatopancreatic weight, hepato -somatic index and embryonic length and weight.

Eclampsia and preeclampsia is an acute and life threatening complication during pregnancy.Hydralazine hydrochloride is one of the drugs of choice in treating this condition The purpose of the present research work was to formulate the orodispersible tablets by using different methods and provide a suitable patient convenience dosage form to enhance the bioavailability and provide quick onset of action. Formulation of orodispersible tablets of Hydralazine hydrochloride were prepared by using various superdisintegrants like crosspovidone, cross caramellose sodium and sodium starch glycolate by direct compression method and camphor as an excipient by sublimation technique. The formulas were evaluated for compatibility and Precompressional studies. The formulations were evaluated for weight variation, thickness, hardness, friability, content uniformity, disintegration time, wetting time, water absorption ratio and release profile. Among all the formulations F9 and SF9 showed effective percentage of drug release at 12 minutes indicating faster and maximum absorption at the site of administration.

An extensive, multi institutional, multi instrumental and multi-platform field experiment ‘Integrated Campaign Aerosols, gases and Radiation Budget (ICARB) was carried out. The objective this Campaign ever conducted in the Indian region was to characterize the physico-chemical properties and radiative effects of the aerosols and trace gases over the Indian landmass and the adjoining oceanic regions of the Arabian Sea, Northern Indian Ocean, and Bay of Bengal. The temporal variations of aerosol optical depth, near surface aerosol mass size distributions and BC mass concentrations show significantly higher aerosol optical depth and near surface mass concentrations during the first and last weeks of April 2007. The mean BC mass fraction in the fine mode aerosol was around of 11 %. A comparison of the temporal variation of the Aerosol properties at Visakhapatnam with the MODIS derived aerosol optical depth along the cruise locations indicate a significant coincidence suggesting that the aerosol transport from the eastern coastal regions of the peninsular India plays an important role on the observed spatial variation in the aerosol optical depths over the near coastal oceanic regions of Bay of Bengal.

Background: A high temperature compared to normal in postoperative first forty-eight hours or immediate postoperative fever is commonly observed and raises anxiety both in the patient than in the caregiver himself. This last is still in trouble whether the fever is related or no to infection especially when the operation is clean. This study aims to determine association between the immediate postoperative fever and infection after clean operations (Class I of Althemeir) in order to limit the misuse of antibiotics and antimalarials. Patients and Methods: This is a prospective study led at the Referral General Hospital of Kabondo, in the city of Kisangani to north-eastern of Democratic Republic of Congo, with 209 operated. Data were recorded on Excel spreadsheet and analyzed with SPSS 20 software. Results: In the immediate postoperative period, 29 (13.87%) operated presented fever. 51.72% of these fevers were moderate around 38°C to 39°C. Caesareans predominated (48.27%). The systemic inflammatory syndrome was found in 55.17% of the cases followed of the malaria in 41.38% of which 37.93% with the positive thick drop. All operated were under a post-operative systematic antibiotherapy (100%) and 55.17% of operated received association antibiotics, antipyretics and antimalarials. Conclusion: Most of immediate post-operative fever after a clean operation is not infectious although malaria remains as significant cause in countries with malaria endemicity.

Present study reports the preliminary qualitative phytochemical analysis of six medicinal plants viz. Amaranthus tricolor L. (Amaranthaceae), Centella asiatica L.(Apiaceae), Chenopodium album L.(Amaranthaceae), Cicer arietinum L.(Fabaceae), Colocasia esculentum L.(Araceae) and Ipomia aquatic L. (Convolvulaceae). The qualitative phytochemical analysis was carried out after extracting sample using soxhlet extraction by using double distilled water, ethanol and methanol as extractants. Various tests were carried out for the detection of phytochemicals such as Alkaloids, Flavonoids, Saponins, Phenols, Carbohydrates, Tannins, Protein and Glycosides in the plant extracts and iron spot was tested by 5% potassium thyocinate solution (KSCN). Our result confirmed the presence of major classes of photochemical and iron in the plant leaves extracts. This preliminary study draws attention to the need for further studies to know the exact active secondary metabolites which is responsible for the treatment of Anemia and other diseases.

The majority of mycotic infections are due to Candida species, out of which Candida albicans is being the most frequently isolated species. Eucalyptus is one of the very important and most widely planted genera across the world. It is a tall, evergreen tree, native to Australia and Tasmania, successfully introduced worldwide, now extensively planted in many other countries. Thus, the aim of the present study was to determine the antifungal activity of eucalyptus oil against clinical isolates of Candida spp. We have observed that, clinical isolates of Candida species were not inhibited in any of these dilutions of this oil. The eucalyptus oil does not have antifungal activity against Candida species. However, it is important to include more number of isolates and different dilutions to validate the results.

Every passing year is marked with one or more catastrophic disaster in world. Natural disasters results in adverse consequences as loss of life, property and economic disruptions. India is vulnerable, in varying degrees, to a large number of disasters. To manage such crisis situation during disasters, there is requirement of dissemination of timely information and knowledge. New emerging technologies are important tool to deal with such situations. This paper analyze role of Geological Information System (GIS) in disaster management. Increased usage of such technology can be effective in disaster management.

Purpose: To compare fracture resistance and primary mode of failure of endodontically treated teeth with three different posts systems and two variant luting agents. Materials and Methods: Root canal treatment was performed on 40 maxillary incisors and samples were divided into 4 groups. For three experimental groups post space preparation was done and teeth were restored with cast post-core (Group B), prefabricated glass fibre post (everStick post) with composite core (Group C) and prefabricated zirconia posts with composite core (Group D). Control group (A) samples were selected with intact coronal structure. Post space was prepared in all samples. Two type of luting cements dual cure resin cement (Luxacore Z) and glass ionomer cement (Fuji I, GC) were used for post cementation. The core was standardized to 4mm × 5mm. Prepared samples were subjected to compressive load of 0.5mm/min at 135o angulation. The load at which fracture occurred and fracture mode were analysed statistically by one way ANOVA, post-hoc tukey test and chi-square test. Results: The findings showed statistically significant difference between failure loads. The mean load required to fracture glass fibre was highest (711MPa) and least for control group (231MPa). The glass fibre posts and zirconia posts showed favorable fracture. Conclusion: The results concluded that endodontically treated teeth without post core system showed least fracture resistance signifying need to reinforce tooth. Use of glass fibre post (everStick post) showed highest mean fracture resistance regardless of luting agent.
目的:比较三种不同桩位系统和两种不同植牙剂对根管治疗牙的抗折性和主要失效模式。材料与方法:对40个上颌切牙进行根管治疗，分为4组。三个实验组分别采用铸造桩核(B组)、预制玻璃纤维桩(everStick桩)复合桩核(C组)和预制氧化锆桩复合桩核(D组)进行桩位准备和牙体修复。对照组(A组)冠状结构完整。在所有样品中都准备了Post space。采用双固化树脂水泥(Luxacore Z)和玻璃离子水泥(Fuji I, GC)两种类型的水泥进行后固井。芯被标准化为4mm × 5mm。制备的样品在1350角方向承受0.5mm/min的压缩载荷。采用单因素方差分析、事后检验和卡方检验对断裂发生载荷和断裂方式进行统计学分析。结果:失效载荷之间的差异有统计学意义。断裂玻璃纤维所需的平均载荷最大(711MPa)，对照组最小(231MPa)。玻璃纤维桩和氧化锆桩均表现出良好的断裂。结论:无桩核系统根管治疗后的牙体抗折断能力最小，提示需要进行牙体加固。使用玻璃纤维桩(everStick桩)，无论使用何种粘结剂，其平均抗断裂能力最高。
