ABSTRACT
This case study describes clinical and molecular genetic data of a 45 days old male patient of neonatal diabetes mellitus. PCR amplification followed by DNA sequencing revealed two point mutations at positions 67A>G and 1009G>A in KCNJ11 gene encoding Kir6.2 protein, a component of the beta-cell ATP-sensitive potassium [KATP] channel which is a key component involved in insulin secretion
ABSTRACT
Present study was conducted to determine the effects of honey on blood hemostasis, in-vitro effect of honey was observed on platelet aggregation and blood coagulation employing, activated partial prothrombin time [aPTT], prothrombin time [PT], thrombin time [TT] and fibrinogen levels in blood. Honey samples showed moderate inhibition of platelet aggregation with IC[50] 5-7.5%. The coagulation assays showed that at higher concentrations [>/= 15%] honey samples increased whole blood clotting time. When assayed in platelet poor plasma [PPP], honey samples significantly [P >/= 0.005] prolonged aPTT, PT, and TT. The honey samples [at 3.75% and 7.5% concentrations] cause mean increment of aPTT = 19 +/- 10% and 62 +/- 10%; PT 6 +/- 5% and 40 +/- 5%; TT 35 +/- 15% and 112 +/- 30% respectively. Moreover, PPP isolated from whole blood pre-incubated with honey samples [9.0% for 10 minutes] showed mean prolongation of aPTT, PT and TT of 45 +/- 21%, 26 +/- 9% and 105 +/- 24% respectively. Interestingly, incubation of honey at 6.25% and 11.75% concentrations in PPP considerably [P >/= 0.005] reduced fibrinogen levels i.e. 13 +/- 4% and 86 +/- 30% respectively. The present study outlines the inhibitory effect of natural honey on platelet aggregation and blood coagulation. These observations provide first line data for modulatory role [s] of honey on process of hemostasis
