Hypoglycemic and Hypolipidemic Effects of Grapefruit Juice in Diabetic Rats

Pages: 10-12 English

Full Text Issues

Abstract

The goal of this study was to investigate the
hypoglycemic effect and the hypolipidemic changes
following the ingestion of an extract of grapefruit juice,
which was fed intra-esophageally, to healthy and
alloxan-induced diabetic male rats.
Treatment of diabetic animals with the grapefruit juice
extract resulted in a significant decrease in the serum
glucose and cholesterol level. The percentages of
decrease are 67.5% for serum glucose level and 30.8%
for serum cholestsrol level, after ingestion of 0.5 ml
twice aday for 12 days. And the percentages of decrease
are 70.6% for serum glucose level and 38.4% for serum
cholestsrol level, after ingestion of 1ml twice aday for 12
days.
This study suggest that grapefruit juice extract play a
good rule in controlling the levels of glucose and
cholesterol in experimental animals and can be applied
clinically on patients with diabetes and lower cholesterol
level.
Although the aqueous extract of grapefruit juice (citrus
paradisi) has strong hypoglycemic and hypolipidemic
properties in experimental animals.

Synthesis and antibacterial activity of some new 1,3,4-oxadiazoles and 1,3,4-thiadiazoles

Pages: 16-20 English

Full Text Issues

Abstract

In this work the synthesis of some mono, disubstituted1,3,4-oxadiazoles and 2-substituted-1,3,4-thiadiazoles are
presented. Starting from some ethyl esters (1-4), the ester
was treated with hydrazine hydrate in ethanol to give the
corresponding hydrazides (5-8). The hydrazides then
treated with formic acid to give 1-formyl-2-acyl hydrazine
(9-12), the synthesized 1-formyl derivatives were
converted to 2-substituted-1,3,4-oxadiazoles and 2-
substituted-1,3,4-thiadiazoles (16-18) by their reaction
with phosphorous oxychloride and phosphorous
pentasulphide respectively. The reaction of acid
hydrazide (6) with the esters (1,2) in presence of
phosphoric acid gave 2,5-disubtituted-1,3,4-oxadiazoles
(19,20). The structure of the synthesized compounds
were established by the physical and spectral methods.
The synthesized compounds (13-20) were tested against
six types of bacteria (Staph. aureus, Bacillus subtilis,
Proteus mirabilis, E. coli, K. pneumonia, Pseudomonas
aemgioson).

Abstract

The synthesis of several new coordination compounds of
cobalt (II), nickel (II) and copper (II) with some Schiff
bases derived from acetylacetone and p-aminophenol
(
L
) or p-aminobonzoic acid (
L

complexes have the general formulae [M(L')2] and
[M(L")2]. All the complexes were characterized by molar
conductance, magnetic susceptibility, IR and UV-Vis
spectra, while cobalt , nickel and copper contents were
determined by standard procedures . IR and UV-Vis
spectral data and magnetic properties suggest that all the
complexes are square-planar. The two ligands coordinate
with the metal (II) ion in a bidentate manner through the
enolisable carbonyl group of acetylacetone and the
azomethine nitrogen atoms.

Effects of Some physical and chemical factors of Lower Zab water on Tigris River

Pages: 85-95 English

Full Text Issues

Abstract

Four stations were selected for water sample collections,
to study the effects of some water characteristics of
Lower Zab tributary on the Tigris river, during the period
from November 2001 to October 2002.
Air and water temperature were (10-38)oC and (10-28)oC
respectively. Salinity values ranged (0.25-0.33)%o .
Turbidity varied from (22) NTU at station 2 to (34.4)
NTU at station 3. pH values ranged (7.5 - 8.6). Dissolved
Oxygen values were higher in Lower Zab water
compared to that of Tigris River. BOD were high at
summer and low during winter.
Total hardness ,calcium and Alkalinity were (222-306)
mg/L, (133-165) mg/L and (134-165) mg/L respectively.
Nutrition values of the water samples were low,
(0.4g/L) for nitrite, (0.27g/L) for phosphate, and (2.1
mg/L) for silica at station 4 after the confluence. While
these values were higher at station 3 before the
confluence (0.6g/L), (0.4g/L) and (2.9mg/L)
respectively. Chloride ions values ranged (33.5-38.6)
mg/L .Discussion of the results of this study clarify that
Lower Zab effects the environment of the Tigris river at
station 4 through the values of the turbidity, total
hardness and negative iones which is located in the river
after the confluence, in addition to the decrease of
nutritive compared to station 3 in the river. This is
certainly due to the favorable conditions at station 4,
which cause blooming and diversity of aquatic
organisms. This was obvious from the BOD5 values at
station 4. The high BOD5 values was proportional to
organic pollutants

Biometric Analysis of Miogypsinidae and their Taxonomic Significance from Azkand Formation (Oligocene-Miocene) in Kirkuk area, Iraq

Pages: 175-190 English

Full Text Issues

Abstract

The investigation is based on a well exposed and
subsurface stratigraphic succession of bioclastic
limestone in Kirkuk area. These sequences were
deposited in a shallow open marine environment during
Chattian to Aquitanian. Test of larger foraminifera
Miogypsinidae are abundant in the lower and upper parts
of this sequence. The internal morphology of the
Miogypsinidae test has been thoroughly investigated.
Biometric analysis on Miogypsina reveals that the oldest
species of Miogypsina are present in the lower part of the
Azkand Formation in the Khabaz well-3 and Qarah
Chauq Dagh sequence represented by Miogypsinoides
complanata and Miogypsinoides formosensis. The early
Miocene association of the Miogypsina s.s. is often
accompanied by associations of Miogypsinoides. Most of
these are close to Miogypsinoides bantamensis. On the
basis of the mean of embryon size ; two types of
assemblage of Miogypsinoides could be distinguished in
the Early Aquitanian sediments. Type I with the smaller
embryon (D1 = 110-125 μm) and Type II with the larger
embryon (D1 = 210-230 μm). The data set for the main
lineage of Miogypsina exhibit a distinct overall change in
morphology of the nepiont, which change is in agreement
with the principle of nepionic acceleration as defined
by[1].
Another abundancy of the Miogypsina s.s. has occurred
in the upper part of Azkand Formation with mean values
of (X) between (9-11) represented by Miogypsina
gunteri-tani, which occurred simultaneously with
Miogypsinoides bantamensis with their mean values of
(X) between (10-13)
