The nature of the inferior ovary in some monocotyledonous families

The floral vasculature aspects of twenty-four species belonging to six monocotyledonous families are dealt with. These selected taxa include 23 horticulture species cultivated in Egypt and the remainders is among the wild flora of Egypt. A great attention has been focused by phylogenetists on the position of the ovary with respect to the other parts of the flower. In this connection, the nature of the inferior ovary is generally discussed on the basis of two theories; appendicular and axial. It is fortunate that the vascular skeleton can still be regarded as the most conservative character and that it may be rather conclusive in the determination of the nature of the inferior ovary. In the present study, the different patterns of floral vascularization are presented in cumulative tables and figures to facilitate the comparative study. Moreover, an interpretation to the observed variations is also tried to reach at the relations between the taxa studied and to determine the nature of the hypanthium

Prevalence of selective IgA deficiency in a sample of Egyptian patients with type 1 diabetes mellitus

Background: Selective Immunoglobulin A deficiency (SIgAD) is known to be one of the most frequent primary immunodeficiency diseases. Several studies worldwide confirm the increased frequency of this disease among type 1 diabetes mellitus (T1DM), yet this has not been studied in Egypt.Objective: This work aimed to define the prevalence of SIgAD among Egyptian patients with T1DM.Patients and Methods: Fifty patients with T1DM were compared to fifty apparently healthy individuals. Serum levels of IgA, IgG, and Immunoglobulin M (IgM) levels were measured by Nephelometry to all participants.Results: The mean age of the diabetic group was 24.5 ± 5.3 years. Thirty out of fifty patients with T1DM (60%) were diagnosed as SIgAD with, female predominance (66.7% of SIgAD). We also found a significant relationship between SIgAD and diabetic ketoacidosis (P-value<0.001). Serum IgA levels were positively correlated to IgG and IgM. Conclusion: The current study displays 60% prevalence of SIgAD among adult Egyptians with T1DM, which is higher than stated in other countries

Efficacy of Co-synch Protocol on Normal Cyclic Dairy Cows with or Without Corpora Lutea

Improving reproductive efficiency, estrus synchronization and controlled breeding protocols are efficient management techniques in dairy cows. Therefore, the present study was designed to compare the efficacy of Co-synch protocol in the cows carrying corpora lutea (CL), without CL or with unexamined ovarian structure. Fifty-six cows were divided into 4 groups; control group1 (n=12) and Co-synch treated groups; group2: cows with unexamined ovarian structure group (n=9), group3: cows having only follicles without mature Cl (n=16) and group4: cows having mature Cl (n=19). Ultrasonography was performed before and after gonadotropin (GnRH) injection. Blood was collected for analysis of progesterone (P4) and estradiol 17-ß. Reproductive data was obtained regarding 1st service conception rate (1st SCR), number of services/conception (s/c) and days open. Ultrasonography revealed luteinization in cows without mature CL. While those having mature CL showed increase in the size of the CL or formation of accessory CL. Results revealed significant decrease in serum P4 before GnRH treatment in cows having no mature CL. Significant increase in serum P4 levels in all groups was recorded after GnRH treatment. Besides, the highest P4 level was assessed in cows having mature CL. Estradiol 17-ß was significantly decreased in cows having mature CL before and after treatment. Cows having mature CL revealed significant upgrade in the percentage of 1st SCR, decrease in s/c and shortening in days open as compared with other groups. In conclusion, applying Co-synch to the cows carrying CL is beneficial and promises protocol to improve reproductive performance in dairy cows
