Diabetes is a major health global problem that has reached alarming levels. The present study aims for studying the effect of date palm pollen (Phoenix dactylifera L.) El-Hayani cultivar on serum glucose and lipids profile in induced diabetic male albino rats. Palm pollen chemically analyzed besides chemical constituents, mineral contents, polyphenols and flavonoids. Male Albino rats (36 rats weight 170-190 gm) were divided into 6 groups. 1: Normal control (-), 2: Alloxanized diabetes control (+) (150 mg/Kg rat body weight). Diabetic groups 3 and 4 had 0.5%, 1.0% date palm pollen, respectively, also diabetic groups 5 and 6 had 100 ppm, 200 ppm date palm pollen extract, respectively. At the end of the

The rapid quantification method of human serum glucose was established by using the Fourier transform infrared spectroscopy(FTIR)and attenuated total reflection(ATR).By the subtracted spectra between glucose aqueous solution and de-ionized water,absorption peaks are calculated in fingerprint *** on these absorption peaks and multiple linear regression(MLR)model,discrete band selection method of absorption peaks disturbance model(APDM)was developed.5 absorption peaks 1150 cm^-1,1103 cm^-1,1078 cm^-1,1034 cm^-1,991 cm^-1 were found in fingerprint *** these absorption peaks to establish absorption peaks disturbance model,the optimal wavelength combinations are 1140 cm^-1,1096 cm^-1,1084 cm^-1,1030 cm^-1,993 cm^-1,the corresponding C-RMSEP and C-RP are 1.164 mmol/L and 0.828 *** results show that the optimal prediction effect of APDM was obviously better than the one of the Partial least squares(PLS)model,and the complexity of the optimal model is reduced greatly *** results also provide a theoretical basis for design of small and portable human serum glucose spectrometer.

Immunocytochemical Localization of Glucagon and Insulin Cells in Eutropis carinata with Respect to Reproductive Cycle

引用

Asian Herpetological Research 2011年第2期2卷 103-109页

作者： Vidya R.CHANDAVAR Prakash R.NAIK Yuvaraja's College University of Mysore Endocrinology Laboratory Department of Studies in ZoologyUniversity of Mysore

The pancreas of Eutropis carinata was studied immunocytochemically for the presence and topographic distribution of glucagon and insulin cells during annual reproductive cycles. The study revealed paracrine arrangement of the two types of ceils. The immunolocalized pancreatic cells revealed significant differences in mean numbers during different periods of reproduction. The numbers of glucagon-immunoreactive （GIR） and insulin-immunoreactive （IIR） cells were highest during the recrudesceut period which corresponded with low serum glucose level. Between the two immunoreactive cells, the GIR cells were predominant. Morphological differences between the two cells were observed by electron microscopy after staining with uranyl acetate and lead citrate. serum glucose showed that cyclic change was highest during the reproductive period.
