Abstract Testicular torsion is a common disorder in males and results blockage of testicular circulation with subsequent damage germ cells. The current work aimed to compare the therapeutic effect platelet-rich plasma (PRP) injectable fibrin (i-PRF) on torsion/detorsion (T/D) injury rats. Forty mature male Wister rats were arranged into 4 groups; (1) Control, (2) T/D, (3) T/D + PRP, (4) T/D+ i-PRF. right testis was twisting 1080° clockwise for 3 h groups 2, 4, then 10 μl PRP or i-PRF...
The current experiment was carried out to measure the effects of different concentrations Fipronil on immune response and health Oreochromis niloticus through evaluation some immunological, biochemical hematological parameters in addition histopathological examination. Two hundred forty were randomly distributed into four groups triplicates. first group served as a control. second exposed 0.014 mg/which equal 1/3 96 hr lethal concentration (96 LC50) for 4 days. third fourth 0.0042 0.002 mg/l...
Copper nanoparticles are widely utilized in a variety of applications, including metal catalysts, semiconductors, heat transfer fluids machine tools, and even antibacterial medications. Forty mature healthy Westar rats were the current investigation grouped randomly into four groups (n = 10 rats/group). Group I (G1) was kept as control group, but G2, G3, G4 intraperitoneally injected with CuO NPs dose (5 mg, 25 mg/kg body weight/day) respectively for 9 days. Rats sacrificed; then, livers...
The main purpose of our study was to examine the role selenium nanoparticles (SeNPs) and/or bee venom (BV) in ameliorating diabetic cardiomyopathy (DCM) and nephropathy (DN) at biochemical, histopathological molecular levels. Fifty male albino rats were used this experiment, divided into five groups: control, Streptozocin (STZ) diabetic, STZ-diabetic treated with SeNPs, BV, SeNPs BV. Biochemically, STZ injection resulted a significant increase serum glucose, BUN, creatinine, CRP, CK-MB, AST,...
Water pollutants cause adverse effects in aquatic ecosystems. The immunomodulatory and mitigating of dietary 1,3-glucan on fipronil lead-induced intoxication African catfish (Clarias gariepinus) were investigated. Two hundred forty randomly divided into four equal groups: those the first group fed basic diet served as controls; second supplemented with β-1,3-glucan (0.1%); third exposed to combination lead nitrate at 0.041 mg/L (1/10 96 h LC50) 2.8 mg/l LC50); fourth fipronil, lead,...
The present investigation was carried out on thirty six mature Westar rats from laboratory animal unit in the faculty of veterinary medicine, Zagazig University, Egypt.The animals were divided into groups for each.Group I considered as a control group.Group II treated with tartrazine only dose 500 mg/kg body weight by oral gavage 30 day.Group III same 300 Royal jelly.Group IV and Code liver oil 0.4 weight.While last two groups, V VI jelly separately above mentioned doses days.At end...
Background: Although, gold nanoparticles (GNPs) are attracting more and attention due to their ease of synthesis, modification great potential value in biomedical application, exhibited harmful effects on human health other living species. Quercetin (Qur) clarify diverse pharmacological specially anti-inflammatory, antiapoptotic, antioxidant ones. Aim: This study aimed evaluate the probable nephrotoxicity induced by different diameters sphere GNPs, as well nephroprotective role Qur. Methods:...
The present study was conducted to investigate the bony structure (i.e., os cordis) in heart of mature Dromedary camel. Ten hearts were collected from healthy camels both sexes aging between 7-9 years. Grossly, camel contained one large, elongated bone embedded inside wall where cardiac muscles inserted and fixed. located at adjacent areas aorta atria. Moreover, it lying atrioventricular plane near junction interatrial interventricular septa, extended anteriorly into valve rings. In...
The current work was carried out to investigate the gross and microanatomical features of moderator bands (septomarginal trabecula) in camel heart. Ten hearts were collected from healthy mature dromedary camels. Anatomically, present both right left ventricles. In ventricle, walls had one muscular band which extended interventricular septum opposite ventricular wall especially papillary muscle. there two bands; muscles, other various places apex running as a thin thread-like across wall....
The present investigation was performed to clarify the histological features of left ventricles in heart mature dromedary camel.This carried out on six healthy camels.Microscopically, is consisted three major layers or tunics; internal endocardium, middle myocardium, and external epicardium.The endocardium layers; endothelial layer simple squamous epithelium, subendothelial loose connective tissue subendocardial that connecting with myocardium housing bundles purkinje cardiomyocytes;...
Ten hearts of mature healthy Buffalo (Bos bubalis L.) were employed to investigate the histological and histochemical structures moderator bands. Hearts gently dissected bands collected. The specimens processed histologically subjected different stains. Grossly, band (Septomarginal trabeculae) was a single muscular that found only in right ventricle buffalo heart. It extended from interventricular septum free ventricular wall especially at base papillary muscle, crossing passing through...
The sinu-atrial node (SAN) is one of the impulse conducting system camel heart. Anatomically, it lies beneath epicardium, at cranial end terminal sulcus, near junction between superior vena cava to lateral wall right atrium and auricle. Histologically, SAN located in subepicardial layer crest can be identified as a mass specialized modified cardiac myocytes. Moreover, appeared elongated shape bent oblong. appears strongly similar general structure glands where, formed two parts; stroma...
The present study was performed to clarify the presence of bony structure; os cordis and cartilage; cartilago in heart mature dromedary camel. This investigation carried out on ten healthy camels. camel contained only one bone. bone is large, elongated embedding inside wall where cardiac muscles are inserted fixed. It found mainly aortic ring; especially adjacent area between aorta left & right atrium respectively. Moreover, it lying atrioventricular plane near junction interatrial...
The current investigation was carried out on the seminal glands of six apparently healthy mature male Buffalo bulls and immature.The specimens were collected examined anatomically histologically after being fixed in 10% buffered neutral formalin.The subjected to processing till paraffin sections obtained stained.The anatomical histological findings are varying with age.Anatomically, immature gland small sized, flaccid texture, white color measured about 0.80-0.95gm weight, 1.95-2.50cm...
The oesophagus is a muscular tube comprised of cervical and thoracic regions. Several studies have clarified the histological structure oesophagus. However, its histoarchitecture in relation to variable dietary habits each species still unclear. In current study, 21 pigeons, cattle egrets ducks, n = 7, was used. Macroscopically, either or parts longest among pigeons ducks. Histologically, four distinct tunicae: mucosa, propria submucosa, musculosa adventitia serosa. A great structural...
Parafollicular cells (C-cells) exist within the thyroid glands and display different distributions among mammalian species. In one-humped camel (Camelus dromedarius), localization of C-cells remains under debate. We herein investigated appearance remnants ultimobranchial body, origin C-cells, in camels. Macroscopically, a white mass was present at one-third length from cranial end where artery entered. addition, large fossae were frequently found adjacent to mass. Histologically, mainly...

Background: Doxorubicin (DOX), an anthracycline antibiotic, is a powerful chemotherapeutic agent effective against multiple types of cancer, particularly lung, breast, bladder and hematologic neoplasia (lymphomas leukemia). However, its therapeutic usage restricted by known cardiotoxicity, which associated with the production oxidative stress. Enhancing antioxidant capacity represents promising approach to mitigate DOX-induced cardiotoxicity. Hesperidin (HES), citrus bioflavonoid, possesses...
