Diabetes decreases the fertility of females, but the mechanisms are not completely understood. In our investigations, we have found that 13% of the female BB Wistar rats that spontaneously developed chemical diabetes had persistent estrous. In this study the ovaries of these rats were examined by scanning electron microscopy(SEM) and compared to normal-cycling controls as well as to rats that had developed polycystic ovaries(PCO) by exposure to constant 1ight.

The ultrastructure of neurosecretory cells and glia cells in the supraoptic nucleus (SON) of the hypothalamus and the neurohypophysis (PN) was studied after rapid freezing followed by substituion fixation. Also, the ultrastructural localization of vasopressin (VP) or its carrier protein neurophys in II (NPII) in the SON and PN was demonstrated by using a post-embedding immunoco1loidal gold staining method on the tissue sections processed by rapid freezing and freeze-substitution fixation.Adult male Wistar rat hypothalamus and pituitary gland were quenched by smashing against a copper block surface precooled with liquid helium and freeze-substituted in 3% osmium tetroxide-acetone solutions kept at -80°C for 36-48h. After substituion fixation, the tissue blocks were warmed up to room temperature, washed in acetone and then embedded in an Epon-Araldite mixture. Ultrathin sections mounted on 200 mesh nickel grids were immersed in saturated sodium metaperiodate and then incubated in each of the following solutions: 1 % egg albumin in phosphate buffer, VP or NPII (1/1000-1/5000) antiserum 24h at 4°C, 3) colloidal gold solution (1/20) 1h at 20°C. The sections were washed with distilled waterand dried, then stained with uranylacetate and lead citrate and examined with Hitachi HU-12A and H-800 electron microscopes.

Coating Formulation

Fried food is convenient for many people due to its pleasant texture and taste. On the other hand, it comes with the risk of high oil absorption which might lead to certain health problems. Resistant starch (RS) has been known to have a functionality of reducing oil absorption. Three different types of banana: Kepok (Musa paradisiaca formatypica), Raja Bulu (Musa paradisiaca L.) and Ambon (Musa paradisiaca L. var sapientum) were evaluated on its performance when utilized as source of resistant starch especially on their application in reducing oil absorption in fried food. Tempeh was used as the food model. Banana starch (RS2) was isolated through water alkaline extraction process, continued with modification process through three repeated cycles of autoclaving-cooling process to obtain the RS3. RS3 was added into the batter coating formulation at three substitution ratios (10%, 30% and 50%) and then used to coat tempeh before frying. Evaluation of resistant starch in batter and battered productwas conducted on the following parameters: fat content, water retention capacity (WRC), coating pick up and sensory analysis. The result of this study revealed that Raja Bulu showed the most effective result on reducing oil absorption in the food tested. In the three bananas used, the ratio of 50% performed best in coating pick up (highest), WRC (highest) and fat content(lowest) parameters, but not significantly different with the 30% ratio. In terms of sensory acceptance, using Raja Bulu as the selected banana type, 30% of substitution ratio was significantly more preferable by the panelists in crispness, oiliness, and overall acceptance attributes compared to control and other substitution ratios.

A study of removal of heavy metal ions from heavy metal contaminated water using agro-waste was carried out with Musa paradisiaca peels as test adsorbent. The study was carried by adding known quantities of lead (II) ions and cadmium (II) ions each and respectively into specific volume of water and adding specific dose of the test adsorbent into the heavy metal ion solution, and the mixture was agitated for a specific period of time and then the concentration of the metal ion remaining in the solution was determined with Perkin Elmer Atomic absorption spectrophotometer model 2380. The effect of contact time, initial adsorbate concentration, adsorbent dose, pH and temperature were considered. From the effect of contact time results equilibrium concentration was established at 60minutes. The percentage removal of these metal ions studied, were all above 90%. Adsorption and percentage removal of Pb2+ and Cd2+ from their aqueous solutions were affected by change in initial metal ion concentration, adsorbent dose pH and temperature. Adsorption isotherm studies confirmed the adsorption of the metal ions on the test adsorbent with good mathematical fits into Langmuir and Freundlich adsorption isotherms. Regression correlation (R2) values of the isotherm plots are all positive (>0.9), which suggests too, that the adsorption fitted into the isotherms considered.
