Abstract: Background: Tribuls terrestris increases levels of various hormones in steroid family including testosterone, DEHA, and estrogen and for this reason improves sport performance, fertility in men and women, sexual function in men and women. There is, at present, lack of scientific confirmation of these supposed benefits. Therefore, this study aims to investigate the possible effect(s) of Tribuls terrestris on the mouse ovarian morphology and function, alone and in combination with other ovulation modulator agent (clomiphene citrate). Materials & Methods: A total of 49 sexually mature healthy Norway albino female mice were used in this study; 25 for pilot study and 24 for the experimental study. Experimental animals were divided into 4 groups, each contained 6 animals. The 1st group was given Tribuls terrestris, the 2nd group was given clomiphene citrate, the 3rd group was given the two agents together, and the 4th group was control. Treatment was given daily for 10 days via orogastric intubation. Histological, histochemical, cytological and morphometrical studies were carried out. Results: demonstrated that Tribuls terrestris alone causes an increase in the number and size of the mature follicles, with no significant change in the total follicular number, with obvious progesterone and some estrogen effects on the otherwise normal vaginal smears. On the other hand, clomiphene alone revealed no mature follicles and no corpora lutea, with strong estrogen-like effect and minimal progesterone effects on the vaginal smears. When Tribuls terrestris and clomiphene were given together, mature follicles and corpora lutea appeared in relatively large numbers, with estrogen and progesterone effects on the vaginal cytology. Conclusion: Tribuls terrestris can stimulate ovulation when given alone, and oppose the anti-ovulatory effect of clomiphene and resume ovulation when given in combination with it.

Postcolonial theory deals with the effects of colonization on the colonized societies and their cultures. It examines the complex relationship between the colonized and the colonizer, and it represents the textual reactions that deal directly with such an issue. It is also a literary critique to texts that carry racist or colonial implications. The emergence of postcolonial theory as an aspect of literary criticism represents a shift in the focus of studies regarding the relation between the western and non-western worlds.
In contemporary theoretical discourse, Edward Said has been among the more influential postcolonial critics to draw attention to the centrality of imperialism in Western culture. Said’s work has provided a th

Therapeutically and prophylactically using Microspheres containing doxycycline isolated from shell of shrimp. Low molecule weight poly lactic acid was prepared. In this study, Poly lactic acid (PLA)/ poly vinyl alcohol (PVA)/poly ethyleneglycol(PEG) loading doxycycline blend solutions was prepared. Also Poly lactic acid (PLA)-Tannin blend via solvent evaporation method was prepared. Microspheres of chitosan/gelatin microsphere loading doxycycline was prepared by emulsion crosslinking technique. Both microsphere and blends were characterized by Fourier transform infrared (FTIR) spectrophotometer. The FTIR spectra were shown distinguish bands. The in vitro release of doxcycline from its matrix at pH 7 was studied. The prophylactic
... Show MoreThe genus Ziziphus is one of the Family Rhamnaceae and consists of more than 170 species distributed in tropical and subtropical regions. All the species in the genus are of economical and medical importance. This study was conducted to identify the morphologically and anatomically features of the genus in Iraq. The field survey was conducted across the study area where 4 species (Ziziphus jujube, Z. mauritiana, Z. nummularia and Z. spina-christi) were collected and used in the study. The result showed that there is variation in morphological and anatomical features among the species in the stem cross-section and longitudinal section of leaves also the differences appeared in the epidermis of leaves.
The spectroscopic properties, potential energy curve, dipole moments, total charge density, Electrostatic potential as well as the thermodynamic properties of selenium diatomic halides have been studied using code Mopac.7.21 and hyperchem, semi-empirical molecular orbital of MNDO-method (modified neglected of differential overlap) of parameterization PM3 involving quantum mechanical semi-empirical Hamiltonian. The relevant molecular parameters like interatomic distance, bond angle, dihedral angle and net charge were also calculated.
Ferrite with general formula Ni1-x Cox Fe2O4(where x=0.0.1,0.3,0.5,0.7, and 0.9), were prepared by standard ceramic technique. The main cubic spinel structure phase for all samples was confirmed by x-ray diffraction patterns. The lattice parameter results were (8.256-8.299 °A). Generally, x -ray density increased with the addition of Cobalt and showed value between (5.452-5.538gm/cm3). Atomic Force Microscopy (AFM) showed that the average grain size and surface roughness was decreasing with the increasing cobalt concentration. Scanning Electron Microscopy images show that grains had an irregular distribution and irregular shape. The A.C conductivity was found to increase with the frequency and the addition of Cobal
