Epoetin alfa ja namaluva nefrotoksicnosta inducirana so cisplatin kaj staorci

Klinickata efikasnost na cisplatin kako antitumorski lek e nesomnena, no dozno-limitiracki faktor za negova upotreba pretstavuva izrazitata nefrotoksicnost. Najnovite istrazuvawa pokazuvaat deka epoetin alfa moze da ima znacajna uloga ne samo vo terapiski celi za korekcija na razni vidovi na anemii, tuku istiot moze da bide efikasen i kako nevroprotektiv, hepatoprotektiv, kardioprotektiv i osobeno znacajno kako nefroprotektiv kaj nefrotoksicnost inducirana od preparati na baza na platina. Glavna cel na ovaa studija bese da se utvrdi efektot na epoetin alfa vo prevencijata na nefrotoksicnost eksperimentalno inducirana so dolgotrajna administracija na cisplatin vo doza od 2 mg/kg/t.t./nedela vo tek na 8 nedeli, kaj Wistar staorci. Dobienite rezultati od ovaa studija pokazuvaat deka epoetin alfa signifikantno gi ublazuva funkcionalnite bubrezni poremetuvawa inducirani so dolgotrajna administracija na cisplatin, ja podobruva opstata sostojba i go namaluva mortalitetot kaj ispituvanite zivotni

Formulation of synbiotic soy-based food product with antihypertensive potential

The specific aims of this study were to select the favorable prebiotic for L casei-01 as well as the suitable inoculum of the probiotic for fermented soy with ACE-inhibitory potential. For that purpose the metabolic activity of L casei-01 in soymilk supplemented with(1.5% w/v) prebiotics Fructooligosaccharide (FOS) or oligofructose enriched inulin (Synergy 1) was assessed. The evaluated parameters were: pH, viable cell counts, proteolysis, organic acid production and inhibition of angiotensine converting enzyme activity (IACE). The cell growth of L casei-01 reached the recommended therapeutic level of 9.58 ± 0.035 log cfu mL-1 for low inoculum samples (0.005 and 0.01%w/v) and 11.543 ± 0.13 log cfu mL-1 for high inoculum samples (0.075 and 0.1%w/v) regardless of the prebiotic used. The lower pH during fermentation, faster cell growth and superior proteolysis in Synergy 1 samples indicated better utilization of that prebiotic vs. FOS. The hydrolysis depended on the prebiotic used, showing higher values in Synergy 1 samples. The faster proteolysis was confirmed by SDSPAG electrophoresis. The Mw of polypeptides in the synbiotic end-products were lower than 30kD. The observed values for inhibition of ACE activity were app. 71, 74, 77 and 78% for inoculum rates of 0.005, 0.01, 0.075 and 0.1% w/v, respectively. Based on the results obtained in our study, the prebiotic Synergy 1 (1.5% w/v) and L. casei-01 at inoculum of 0.01% w/v for low dose and 0.075% w/v for high dose were considered more favorable for the production of synbiotic soy drink with antihypertensive potential
