2023-05
Technium BioChemMed
The main objective of this study was to compare the demographic
characteristics and histological changes in the amniotic membrane (AM) of
gestational diabetes mellitus (GDM), pregestational diabetes mellitus (PGDM),
and non-diabetic women. A total of thirty AM samples (n = 10 for each group)
were obtained from full-term pregnant women without any complications.
These samples were processed for paraffin blocks, sectioned, and stained with
H&E. The results of demographic characteristics showed the mean maternal age
of the PGDM and GDM groups was significantly higher compared with the
control. Neonatal weight decreased significantly in the PGDM group, but both
diabetic groups showed no significant differences between them in terms of
maternal age and neonatal weight. A random blood sugar (RBS) test and WBC
count showed a highly significant increase in GDM and a significant increase
in PGDM. The highest significant value of RBC was recorded for PGDM. The
thickness of the epithelial layer plus the basement membrane (BM) was
significantly increased due to the PGDM. while the compact layer plus the
fibroblast layer and the total thickness of AM showed a significant increase in
GDM. The nucleus diameter of AM epithelial cells was significantly decreased
in diabetic groups. The histological examination revealed that both diabetic
groups caused several changes and damage in AM, including: hypertrophy and
hyperplasia in epithelial cells associated with the formation of the vacuole
between them; degeneration of some of these cells that pinched off from the
lining epithelium; breakdown of the compact and fibroblast layers and caused
damage to the stromal collagen fibril; epithelial cells and their nuclei became
elongated and resembled columnar epithelium; and the basement membrane
appeared thicker in comparison to the control group. In conclusion, GDM and
PGDM induced various alterations and damage to the AM, which in turn
delayed embryonic development and the delivery
Histological and Morphological Study of the Placenta in Gestational: Pregestational Diabetic, and Normal Women’s

This study was aimed at comparing the morphometric and histological features of the placenta in gestational
diabetes mellitus (GDM), pre-gestational diabetes mellitus (PGDM), and non-diabetic normal pregnant women.
Twenty-four placentas were obtained from non-diabetic pregnant women (control group), ten from women with
GDM, and ten from PGDM women. Segments from the central part of the placenta were taken and processed for
paraffin blocks, sectioned, and stained with H&E, Masson trichrome, and periodic acid-Schiff. The results of
morphometric measurement revealed that the mean weight and diameter of GDM and PGDM placentae were
significantly higher than in the control; placental thickness was a significant increase in PGDM; the number of
cotyledons and fetal weights showed no significant difference in all these groups; the fetoplacental ratio was
significantly higher in the PGDM; discoidal placenta shape, followed by irregular, oval, and kidney as the most
common shapes recorded in these groups; the central umbilical cord insertion was most common in all three groups;
followed by noncentral (eccentric) and marginal insertions. Diabetes caused several histopathological changes in
the placenta, including an increase in the number of different sizes of villi with a decrease in the intervillous spaces,
an increase in the: number of big syncytial knots, and fibrinoid necrosis; chronogenesis in the intervillous spaces
and villous capillary congestion. Diabetic groups showed the presence of dense collagen fibers within the villous
stroma (villous stromal fibrosis) and around fetal blood capillaries. GDM showed a mild thickening of the
basement membrane (BM) of chorionic villi and a mild increase in the collagen in the villous stroma. While PGDM
showed a moderate increase in the BM of syncytiotrophoblast and villous stroma and mild thickening of the BM
of capillary blood vessels. In conclusion, both GDM and PGDM caused adverse effects on the histological and
morphometrical features of the placenta.
Protective Effects of Vitamin C and E Against Monosodium Glutamate Induced Histological Changes in The Epididymis of Adult Male Albino Rats

THE purpose of the current study was to investigate the possibility of vitamin (Vit.) C and
E in protecting rat epididymis from MSG-induced histological changes. Twenty-five adult
male albino rats divided into five groups (n=5): control, MSG; MSG+Vit.C.; MSG+Vit.E. and
MSG +Vit. C+Vit. E. This treatment lasted for forty days. The histological examinations include
use of H&E stain and Masson trichrome and histochemical (Periodic Acid Schiff reaction
(PAS)). The present results showed that, all groups’ B.W. after treatment was significantly
higher than that before treatment. However, after treatment, MSG, and MSG+Vit. E caused
a high significant decrease in B.W., respectively. There were no appreciable variations in the
epididymis weight between the groups MSG+Vit. E and MSG+Vit. C+Vit. E. Histological
investigations, indicated none of the treated groups significantly altered the bulk of the
epididymis tissues, except for some histological alteration; however, the MSG+Vit.C+Vit.E
group showed few effects. These alterations include blood vessel congestion, inflammatory cell
infiltration, giant cell formation, expansion of interstitial spaces, hyperplasia and vacuolation of
epithelial tubule lining, and hydropic degeneration. MSG show marked deposition of collagen
fibers in the capsule, epididymal tubules, interstitial space and basal lamina. While remaining
groups indicated the presence of the moderate amount of collagen fibers. Basal lamina and
interstitial cells in groups of the MSG; MSG+Vit.C. and MSG+Vit.E. ; exhibited a strong PAS
response. Whereas, the MSG+ Vit.C+ Vit.E group had moderate PAS reaction. In conclusion,
combining Vit. C and Vit. E with MSG may lessen its toxicity. It is imperative to reevaluate the
use of MSG as a flavor enhancer

Effects of Feeding Oak Acorn Flour on Hematology and Serum Biochemical Profile, and Carcass Characteristics of Japanese Quail
2022-12
Egyptian Journal of Veterinary Sciences (القضية : 2) (الحجم : 54)
THIS research was aimed to determining the influence of oak acorn flour on the body, liver
and kidney weight, and some (hematological and biochemical) parameters of quail. One
hundred quail birds (7 days old) were divided into five groups (n = 20 for each group). Group
1: Control group received a normal protein diet (NPD) containing no oak flour (0%). Groups
2, 3, 4, and 5 (experimental groups) received 5, 10, 15, and 20% oak flour in NPD, respectively. The results showed no significant differences in mean body and organ weight between
treated and control groups, but except for the concentration of 5% showed significant increase
in body weight over six weeks when compared with control. No significant differences were
also recorded in the hemoglobin and packed cell volume in both treated and control groups.
When compared to the control group, group 5 (20%) had a significant increase in the number
of heterophils cells and a significant decrease in the number of lymphocytes. While other types
of leucocytes showed no significant changes in their numbers in all groups. Treatment with oak
acorn flour showed no significant effects on levels of all biochemical parameters enrolled in
this study in all groups. In conclusion: Quail feeds could contain 20% oak acorn flour seemed
to be save and without adverse effects on the body and organ weight, and all blood parameters.
Oak acorns could be employed as a source of energy in a quail diet, and their nutritional value
is equivalent to that of cereal grains
