Aim: The aim of the study is to estimate changes in the levels of biochemical parameters as fasting blood sugar (FBS), postprandial blood sugar (PP2BS) and glycosylated hemoglobin (HbA1c); and immunological parameters as Complement proteins C3, Complement proteins C4, Immunoglobulin's (IgA, IgE, IgG, and IgM) and C-peptide of type 2 diabetic patients to obtain a full immunological and physiological profile for type 2 diabetes. Subjects and Methods: Blood samples from 25 type 2 diabetic patients and 5 healthy subjects were randomly selected from Banha University hospitals in Kalyubiyya, Egypt. Serum sugar and glycosylated hemoglobin were assayed by using chemical analyzer (chem 7). C3, C4, IgA, IgE, IgG, IgM and C-peptide were measured by ELISA Results: FBS, PP2BS, and HbA1c significant increase in type 2 diabetic patients compared to healthy subjects. C3, IgA, IgE, IgG, and C-peptide showed a significant increase in type 2 diabetic patients compared to healthy subjects. Conclusion: FBS, PP2BS, and HbA1c used as good tools for the diagnosis of diabetes mellitus. Type 2 diabetes in the current studied subjects is characterized by alternative pathway activation. Immunological biomarkers such as C3, IgA, IgE, and IgG were increased in type 2 diabetic patients by poor control of diabetes and long duration of disease. }, keywords = {Diabetes mellitus,immunological parameters,Egypt}, url = {https://eajbsz.journals.ekb.eg/article_103183.html}, eprint = {https://eajbsz.journals.ekb.eg/article_103183_239313b51373880721135b92e2cdf55e.pdf} } @article { author = {Olaleru, Fatsuma and Olugbebi, T. and Fasona, M.}, title = {Morphological Studies on the Guard Hair of the Mona Monkey (Cercopithecus mona) in Omo-Shasha-Oluwa Forest Reserves of Southwest Nigeria}, journal = {Egyptian Academic Journal of Biological Sciences, B.

Morphological characteristics of the guard hairs were used to determine differences in the pelage of mona monkeys (Cercopithecus mona) in Omo-Shasha-Oluwa Forest Reserves in South western Nigeria. Using standard procedures, five strands of guard hair from each location were observed under a light microscope attached with a digital camera for the determination of histological structures. Qualitative and quantitative characteristics of the hair were examined and data obtained directly from the microscope. Data on the cuticle, cortex and medullar dimensions (μm) of the hair were analysed descriptively and inferentially using SPSS Version 20 respectively. Variance analysis was used to compare the means of the quantitative parameters of the hair. Statistically significant means (P ≤ 0.05) were separated using LSD post hoc test. A continuous medulla pattern was common in all locations. Amorphous medulla was found in only Omo and Shasha monkeys. The longest scale length and width of 218.76 ± 60.29μm and 725.76 ± 155.91μm respectively were recorded in Omo Forest Reserve. Medullary diametre, index, and a fraction of monkeys in Omo and Shasha were significantly different (P ≤ 0.05) from that of Oluwa. Based on the qualitative and quantitative characteristics of the guard hair, the mona monkeys in Omo and Shasha had features that were similar. The findings can be useful in explaining the close proximities and interactions of this species in the three Reserves.

In the current investigation, 20 male albino rats were equally divided into four main groups (n = 5); Group1 (control): Animals were received the ordinary water and diet. Group2 (L- arginine): Animals were given L- arginine at a dose of 200mg/kg/day for a month by oral gavage. Group3 (acrylamide): Animals were given Acr at a dose of 50mg/kg/day for a month by oral gavage. Group4 (Acrylymide+ L-arginine): Animals were given Arc (50mg/kg/day) together with L-arginine (200mg/kg/day) for a month by oral gavage. The results of the present work concluded that Acr is a genotoxic agent, it induced a significant increase in the frequency of total chromosomal aberrations (numerical and structural).

There are 35,000 described species of land snails (subclass: Pulmonata) from class gastropods in the world. With the present scenario of climate change, their occurrence has been observed many-fold. Despite their economic importance, population diversity and distribution of these creatures on different host crops in Punjab Pakistan is not much more studies. For this purpose, the present study was conducted to identify the snail species and their diversity on different hosts in the agroecosystems of Multan. The snails were collected from different crops like wheat, vegetable (spinach), fodder, citrus orchard, and plant nurseries. A total of 8264 specimens were collected and preserved in the form of a dry shell and 70% alcohol in Ecology Lab, MNS - the University of Agriculture, Multan for identification purpose. The preserved specimens were identified under microscope using available taxonomic keys. Ariophanta bistrialis ceylanica, Ariophanta bistrialis cylix, Ariophanta solata, Oxychilus draparnaudi, Monacha catiana, Cernuella virgata, Pupoides abilabris and Oxyloma elegans were identified during the study. The highest and lowest population of Ariophanta bistrialis cylix (1592) and Ariophanta solata (446), respectively was recorded. The population diversity was found maximum in plant nurseries followed by fodder crop (Berseem) and citrus orchard while least in vegetable (Spinach) and wheat crop. The maximum population was found in July and August, while least in March and May. In the rainy season, the population of snails was recorded maximum as compared to the dry season. }, keywords = {snails,Pulmonata,Ariophanta bistrialis ceylanica,Oxychilus draparnaudi,Population diversity,Multan}, url = {https://eajbsz.journals.ekb.eg/article_125508.html}, eprint = {https://eajbsz.journals.ekb.eg/article_125508_7c156d112c3882251590cb8515ed84f9.pdf} } @article { author = {Riad, Saber}, title = {Quantity of Spring Migration of Migratory Soaring Birds Over the Eastern Desert of Egypt}, journal = {Egyptian Academic Journal of Biological Sciences, B.

In the present experiment, the concentration tested was 2.325 μg/l as 1/10 of the determined LC50 - 96 hours was used for 28 days. The experimental design represents 6 groups: group 1 was control (cont.), group 2 was treatment with lambda-cyhalothrin (LCT) and two algae species with two concentrations each (5% and 10% of diet + lambda-cyhalothrin) are the other four groups. After the experimental period, serum biochemical tests (Glucose, Total Protein, Albumin, Globulin, AST, ALT, Urea, Creatinine and lipid profile) were determined. All biochemical analysis showed significantly varied in-between treatment except urea levels, while, these parameters were in normal rang in fish groups fed by both concentrations of SP and US. The residue levels of lambda-cyhalothrin in water samples were decrease in 10% concentration compared with 5% concentration in both algae. SP and US with two concentrations can efficiently remove lambda-cyhalothrin residues in fish muscles. Water quality (temperature, dissolved oxygen and pH) were no significant differences between all treatments from the beginning till the end of the experimental period.
