PROTECTIVE EFFECT OF DIOSGENIN AGAINST CARBON TETRACHLORIDE AND CISPLATIN INDUCED HEPATOTOXICITY IN RATS

Background: Activation of hepatic stellate cells (HSC) plays central role in the development of liver fibrosis. In HSC activation, the transforming growth factor-1 (TGF-1) is considered to be the main stimuli factor. Diosgenin are the steroidal saponin and found in Trigonella foenum graecum Linn (Fenugreek) and some other species of Dioscorea. Diosgenin attenuates HSC activation by inhibiting transforming growth factor. Aim: In present study an attempt was made to explore the effect of diosgenin on liver fibrosis. Methods: Liver fibrosis was induced in rats by carbon tetrachloride (CCl4) 1 ml/kg intraperitoneally twice a week for 28 days and cisplatin 3mg/kg intraperitoneally at 0, 1, 3 week for 4 weeks. The extent of liver fibrosis was assessed by measuring the weight of liver and levels of total bilirubin (TBL), hydroxyproline (HP) and serum enzymes due to deposition of extracellular matrix (ECM). Results: The administration of diosgenin reduced the liver weight of CCl4 and cisplatin treated animals and reduced the TBL, HP level and serum enzymes significantly and inhibited liver fibrosis induced by CCl4 and cisplatin. Conclusion: The result obtained in the present investigation, Diosgenin treatment exerted significant hepatoprotective effect in animals by inhibiting ECM deposition and HSCs activation

Evaluation of Immunomodulatory activity of Diosgenin in rats

Background: The immune system is intrinsic to health. Modulation of the immune responses to alleviate the diseases by using herbal plants has been of interest for many years. Diosgenin, a naturally occurring steroid saponin mainly present in the seeds of fenugreek (Trigonella foenum graecum) and in the root tubers of wild yams (Dioscorea villosa). Activation of specific and nonspecific immunity results in stimulation of immune response. Diosgenin has the positive effects on both specific and nonspecific immunity. Aim: To study the immunomodulatory activity of Diosgenin in albino wistar rats. Method: The suspension of Diosgenin was given orally at the dosage level of 50, 100 and 150 mg/kg for 21 days in a rat. The immunomodulatory activity on specific and non-specific immunity was studied by heamagglutination antibody (HA) titer, delayed type hypersensitivity (DTH) response and carbon clearance test. Immunosuppression in a rat was induced by using Cyclophosphamide (100 mg/kg, p.o.). Sheep red blood cells (SRBCs) were used as antigen (0.1ml 20% SRBCs). Result: Diosgenin exhibited significant increase in the production of antibody titer in response to SRBC antigen. A significant increase in both primary and secondary HA titer was observed in immunosuppressed group treated with Diosgenin when compared with negative control. A significant increase in the DTH response was observed in immunosuppressed animals treated with Diosgenin, pre-sensitized with SRBCs antigen. Diosgenin exhibited significant increase in phagocytic index against control group, indicating the stimulation of the reticuloendothelial system. Conclusion: The study indicates that Diosgenin triggers stimulatory effect on specific and nonspecific immune response. The immunostimulant effect of Diosgenin could be attributed due to its saponin glycoside

Accident Prevention Systeam Using Android Application

Mostly, it is found that road accident happening are more frequent at certain specific locations i.e. black spot. The analysis of these black spot can help in identifying certain road accident factor that makes a road accident to occur frequently in that location. In this project we apply statistics analysis and data mining algorithms on the Fatal Accident dataset as an attempt to address this problem. Association rule mining is one of the popular data mining techniques that identify the causes of accident of road accident. In this project, we first applied k-means algorithm to group the accident locations into four levels, zero level, first level, second level and third level accident location. K-means algorithm takes accident level count as a factor to cluster the locations. Then we will use association rule mining to identify these locations. The rules show different factors associated with road accidents at different locations. For all this we will provide accident data that are issue from Nasik city commissioner office. Safety driving suggestions will be making based on accident data, association rules, classification model, and clusters obtained
