Turkish Journal of Biology
The aim of the present study was to determine the effects of dietary vitamin E on some biochemical sera parameters in diabetic rats. Thirty wistar rats were used in the experiments. They were randomly divided into three groups, each consisting of ten rats. The first group was the control, the second was diabetic, and the third was diabetic but fed vitamin E. At the end of 12 weeks, the levels of insulin, HDL and vitamin E in the sera were lower but the levels of MDA, glucose, fosfolipidis, cholesterols, triglycerides, free fatty acids, LDL and VLDL were in the second …

Production Of \Alpha -Galactosidase Usingbacillus Stearothermophilusvar. Caldiloactis C953, E. Esin Kocabaş, Mücahit Di̇zbay
Turkish Journal of Biology
An intracellular, thermostable a-galactosidase (a-D-galactoside galactohydrolase EC 3.2.1.22.) was produced from a strain of Bacillus stearothermophilus var. calidolactis C953. It was found that the presence of NH 4 Cl in the fermentation medium affected microbial growth and that optimum enzyme production occurred with peptone in various sources of nitrogen where NH 4 Cl was used as the main inorganic nitrogen source. After peptone, in decreasing order of enzyme productivity, came tryptone, soybean meal, soya-neutralized peptone and casamino acid. It was determined that, in various carbon sources, raffinose produced the highest a-galactosidase activity, followed by melibiose, D-galactose and molasses, and that …

The Carbohydrate Requirements Of Melanogryllus Desertus Pall.(Orthoptera: Gryllidae), Ruken Mehmetoğlu, Mehmet Başhan
Turkish Journal of Biology
The qualitative effects of 24 different carbohydrates on the growth and survival of the black cricket Melanogryllus desertus Pall. were investigated by rearing the insect on synthetic diets. The results showed that the carbohydrates examined had different effects on the growth and survival of the insect. Rhamnose and lactose had inhibiting effects, whereas ribose, arabinose, xylose, galactose, sorbose, cellobiose, inuline and dulcitol produced an inert effect. Sucrose, maltose, glucose, fructose, mannose, trehalose, dextrin, glycogen, starch, sorbitol, manitol all had positive effects. Raffinose, mellibiose and inositol were utilized at very low levels by the black cricket. Of the monosaccharides, glucose promoted …

The Effect Of Fish Size On Pigmentation In Goldfish ( Carassius Auratus), Mahmut Yanar, Nazmi Tekeli̇oğlu
Turkish Journal of Biology
The effect of fish size on pigmentation of gold fish ( Carassius auratus) was ivestigated. The total carotenoid deposition in the skin of four different size groups of fish fed a diet containing zeaxanthin (75 mg/kg) for 60 days was determined spectrophotometrically. The results were as follows: 19.23±0.46 mg/kg for the 1.52 g weight group, 29.06±0.64 mg/kg for the 4.19 g weight group, 31.10±0.53 mg/kg for the 7.35 g weight group and 35.28±0.65 mg/kg for the 13.11 g weight group. According to these results, it was concluded that pigmentation increased with fish weight.

A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu
A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu
Turkish Journal of Zoology
There has been a much debate about the relative importance of the determination of phytoplankton crops by nutrients (bottom-up control) or by zooplankton grazing (top-down control). Wide acceptance of the importance of nutrient concentrations in water quality deterioration has brought about external nutrient control by which eutrophication is, to some extent, reversible, and which has been proved its effectiveness mostly in deep lakes. In shallow lakes its effectiveness has not been as pronounced, owing to internal nutrient loading. Because the non-linearity of responses of biological systems is much more accentuated in small and shallow lakes. The use of profound effects …

The Use Of Coefficient Of Difference (Cd) In Systematic Zoology And The Subspecies Concept, C. Can Bi̇lgi̇n
The Use Of Coefficient Of Difference (Cd) In Systematic Zoology And The Subspecies Concept, C. Can Bi̇lgi̇n
Turkish Journal of Zoology
The use of the Coefficient of Difference (CD), which was first suggested some 50 years ago, as a measure of difference of a single character between two populations is not recommended today on grounds of statisticial weakness, its inability to evaluate more than one character simultaneously, and the often discordant variation of the characters studied. It is useful to utilize the statistically proven t-test or analysis of variance in cases when a few characters are studied, while multivariate distance measures such as Euclidian distance or discriminant function analysis will help determine differences between groups and taxon boundaries when many characters …

Turkish Journal of Biology
The pyrimidine and pyrimidine-derived secondary compounds of Phaseolus aureus and Glycine max were investigated. Batches, each consisting of one hundred 12-day-old seedlings of either P. aureus or of G. max were separately extracted in cold dilute (0.6 M) perchloric acid. After preliminary purification of extracts by charcoal adsorption and elution, and by PVP treatment, the extracts were subjected to paper chromatography and high voltage paper electrophoresis. The UV-absorbing bands were detected by viewing chromatograms and electrophoretograms under UV-light and, where possible, identified.

Turkish Journal of Biology
In this study, 34 white cheeses and 16 civil (local name) cheeses purchased from markets and shops in Erzurum during the period of January 1995-April 1996 were analysed. The samples were streaked directly onto LSA and Palcam Agar media in Petri Plates and incubated at 37C° for 48 hours. After the incubation, the growing colonies on LSA-agar plates were examined by Henry's Modified IIIumination Method while collonies on Palcam agar were examined by naked eye. Typical colonies were selected and used for several biochemical tests. As a result, it was found that only one sample (2.94%) of the white cheeses …

This study has been carried out to determine the bud fruitfulness (number of bunches/bud) according to their rank on the one year old cane of nine grape varieties grown in Amasya, in 1997 and 1998. For this aim, the first ten buds from base to the top of the cane were shooted under vineyard condition. It has been determined that the maximum bud fruitfulness (number of bunches/bud) differed between 2^nd and 4^th buds and the basal first bud of Antep, Asılasma, Bursa, Horozyüreği and Kızılsirke grape varieties has lower than one bunch. It was determine that the buds on 3^rd …
