Impact of ß-glucan dietary supplementation on productive, reproductive performance and physiological response of laying hens under heat stress conditions.

The exploration for effective in-feed additives is growing owing to the global climatic change trend to alleviate the negative effects of heat stress in laying hens. This research assessed the potential of using B-glucan (G) as an antiheat stress agent in Matrouh laying hens subjected to early heat shock programs during the growing period. Factorial design (3 × 3) was used, including 3 levels of heat stress (control, heat shock at 3 d and at 3 d and 8 wk of age) and 3 levels of ß-glucan (0, 100, and 200 mg ß-glucan /kg diet). During the first 12 wk of egg production (EP), treatments were exposed to heat challenge. The results revealed that heat shock program applications at 3 d and 8 wk of age significantly decreased body weight at 36 wk of age (P < 0.05) and reduced (P < 0.05) feed intake (FI). While significantly (P < 0.05) improved feed conversion ratio (FCR), hemoglobin, RBCs, WBCs, immunoglobulin M (IgM), immunoglobulin G (IgG), and Heat shock protein (HSP70) of the Liver (P < 0.01) as compared with the control group. At the same time, there was a decrease in lymphocyte%, H/L ratio, cortisol, and T3 compared to the thermo-neutral control. When compared to the control group, hens fed a diet containing 200 mg of ßG significantly (P < 0.05) improved body weight at 16 wk and final weight at 36 wk, feed conversion (FCR) (g. feed/g. egg mass), hen-day egg production, and egg mass, as well as the digestibility coefficients of crude protein (CP), dry matter (DM), metabolizable energy (ME), and cortisol. The interactions between heat chock programs and ßG levels were nonsignificant for the most studied traits except daily feed intake. Therefore, the early heat shock exposure 2 times and supplementation of Β-glucan (ßG) at 200 mg/kg diet during the growth period for laying hens that are exposed to heat stress during the reproductive period could improve productive, reproductive performance, HSP70 level and enhance immunity responses.

Comprehensive chemical profiling of Bassia indica Wight. aerial parts extract using UPLC-ESI-MS/MS, and its antiparasitic activity in Trichinella spiralis infected mice: in silico supported in vivo study.

BACKGROUND: Trichinellosis is a public health threat infected both animals and humans as a result of eating undercooked meat. It caused by Trichinella spiralis that has widespread drug resistance and even developed many sophisticated strategies for their survival, this increases the demand in searching for new anthelmintic drugs from natural source. METHODS: Our objectives were to test the in vitro and in vivo anthelmintic activity of Bassia indica BuOH frac., and to characterize its chemical composition using UPLC-ESI-MS/MS. Besides an in silico molecular docking study with the prediction of the PreADMET properties. RESULTS: In vitro investigation of B. indica BuOH frac., showed severe destruction of the adult worm and larvae, marked cuticle swelling, areas with vesicles, blebs and loss of annulations. This was assured via in vivo study, which revealed a significant reduction (P < 0.05) in the mean adult worm count with efficacy of 47.8% along with a significant decrease (P < 0.001) in the mean larval count per gram muscle with efficacy 80.7%. Histopathological examinations of the small intestine and muscular sections showed marked improvement. In addition, immunohistochemical findings demonstrated that B. indica BuOH frac. depressed the proinflammatory cytokines expressions of TNF-α, which was obviously upregulated by T. spiralis. Precise chemical investigation of the BuOH frac. using UPLC-ESI-MS/MS resulted in the identification of 13 oleanolic type triterpenoid saponins; oleanolic acid 3-O-6´-O-methyl-ß-D-glucurono-pyranoside (1), chikusetsusaponin-IVa (2) and its methyl ester (3), chikusetsusaponin IV (4) and its methyl ester (5), momordin-Ic (6) and its methyl ester (7), betavulgaroside-I (8), -II (9) -IV (10), -X (11), licorice-saponin-C2 (12) and -J2 (13). In addition, 6 more phenolics were identified as syringaresinol (14), 3,4-di-O-caffeoylquinic acid (15), 3-O-caffeoyl-4-O-dihydrocaffeoylquinic acid (16), 3,4-di-O-caffeoylquinic acid butyl ester (17), 3,5-di-O-galloyl-4-O-digalloylquinic acid (18) and quercetin 3-O-(6´´-feruloyl)-sophoroside (19). The auspicious anthelmintic activity was further ascertained using in silico molecular docking approach that targeted certain protein receptors (ß-tubulin monomer, tumor necrosis factor alpha (TNF-α), cysteine protease (Ts-CF1), calreticulin protein (Ts-CRT)), all the docked compounds (1-19) fit into the binding site of the active pocket with binding affinities noteworthy than albendazole. In addition, ADMET properties, drug score and drug likeness were predicted for all compounds.

Diminished CCl4 -induced hepatocellular carcinoma, oxidative stress, and apoptosis by co-administration of curcumin or selenium in mice.

Hepatocellular carcinoma (HCC) is a lethal disease, and in HCC advanced stages, there is limited therapeutic efficacy. HCC results in a complication of fibrosis or cirrhosis. In this study, the protective effect of curcumin and selenium versus hepatocellular carcinoma caused by CCl4 in experimental animals was investigated. In all, 70 mice were divided into seven groups to study the effect of curcumin and selenium on CCl4 -induced hepatocellular carcinoma. After treatment time, different animal groups were sacrificed, serum and liver samples were collected and processed for assay of biochemical and molecular parameters. Our results showed that CCl4 administration induced various alterations such as significant elevation in the serum levels of ALT, AST, and hepatic contents of malondialdehyde (MDA), and depletion in the levels of antioxidant parameters. CCl4 induced apoptosis in the hepatic cells indicated by an increased level of p53, CD4, CD8, Bax, and Annexin V/PI in addition to significant decrease in the level of Bcl-2. Administration of curcumin and selenium restored this abnormal variation in these biochemical parameters to normal values. Our study addressed that curcumin or selenium may be helpful in the protection against liver damage induced by CCl4 . The hepatoprotective impact of curcumin or selenium might be mediated primarily by its potent antioxidant activity. PRACTICAL APPLICATIONS: Hepatocellular carcinoma (HCC) ranked third common cause of death, primary liver cancer. Exposure to CCl4 was found to induce significant hepatotoxicity, characterized by fibrosis, bile duct proliferation, cirrhosis, and reduced hepatic function The work was prepared to investigate the protecting capacity of curcumin, selenium alone, and in combination against HCC induced by CCl4 in the experimental animal model. This study proved the protective effect of curcumin and selenium, alone and in combination with each other, where curcumin showed multiple pharmacological activities, including anti-inflammation and antioxidant, and have an essential role in inhibiting the progression of HCC.

Acaricidal activity of Artemisia herba-alba and Melia azedarach oil nanoemulsion against Hyalomma dromedarii and their toxicity on Swiss albino mice.

Biopesticides such as essential oils (EOs) are considered an improvement for integrated pest control as they appear to be less toxic to the environment than chemical acaricides. The current study aimed to evaluate the acaricidal activity of Artemisia herba-alba and Melia azedarach oil loaded nano-emulsion as alternatives for chemical acaricides against the camel tick Hyalomma dromedarii, besides evaluating their toxic effect on Swiss albino mice. Transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) were used for the characterization of loaded nano-emulsions.The immersion test was used for the bioassay of both loaded nanoemulsions on tick stages (egg, nymph, larva, and adult). Mortality percentages and LC50 values of each tick stage were calculated. Reproductive performance for the survived engorged females after treatment was monitored. The toxicity of both loaded nano-emulsions was evaluated on Swiss albino mice by an oral dose of 1500 mg/kg/day for five successive days. The hematological, biochemical, and histopathological changes were evaluated. TEM characterization revealed spherical droplets for A. herba-alba and M. azedarach oil loaded nano-emulsion with droplet size ranging from 62 to 69 nm and 52-91 nm, respectively. FTIR revealed the absence of extra peaks in the loaded nano-emulsions that confirmed no chemical changes existed by ultrasonication. The LC50 values of A. herba-alba and M. azedarach oil loaded nano-emulsion on embryonated eggs, larvae, engorged nymphs, and unfed adults were 0.3 and 1.1%, 0.7 and 1.7%, 0.3 and 0.4%, 4.4 and 22.2%, respectively. The egg productive index (EPI), egg number, and hatchability percentage were lower in the treated females compared with Butox 5% (deltamethrin) and control. The hematological picture and biochemical analysis revealed insignificant changes in the treatment group compared with the negative control group. The liver of the A. herba-alba and M. azedarach oil loaded nano-emulsion treated group exhibited vacuolar degeneration and infiltration of lymphocytic cells. The kidney of mice treated with A. herba-alba and M. azedarach oil loaded nano-emulsion showed hemolysis and slight degeneration of epithelial cells of tubules. It is concluded that A. herba-alba and M. azedarach oil loaded nano-emulsion have good acaricidal activity against camel tick H. dromedarii.

In vitro acaricidal activity of green synthesized nickel oxide nanoparticles against the camel tick, Hyalomma dromedarii (Ixodidae), and its toxicity on Swiss albino mice.

The green synthesized nanoparticles have been determined as a novel pesticide against arthropod pests. This study was designed to evaluate the in vitro acaricidal activity of green synthesized nickel oxide nanoparticles (NiO NPs) using aqueous extract of Melia azedarach ripened fruits against different developmental stages of the camel tick Hyalomma dromedarii in addition to their toxic effect on laboratory animals. The synthesized NiO NPs were characterized by UV-visible (UV-Vis) spectroscopy, Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). The UV-Vis spectra of the NiO NPs showed an absorption peak at 307 nm. FTIR analysis showed the possible functional groups used for capping and stabilization of NiO NPs with strong bands at 3416.2 and 1626.6 cm-1. The SEM images of the NiO NPs exhibited a size ranging from 21 to 35 nm. The immersion test was used for the in vitro application of the synthesized NiO NPs on the various tick stages (egg, nymph, larva, and adult). Mortality percentages and LC50 values of each tick stage were calculated. The oviposition and hatchability of the engorged females were monitored for the survived tick after treatment. The LC50 values for NiO NPs on embryonated eggs, larvae, and engorged nymphs were 5.00, 7.15, and 1.90 mg/mL, respectively. The egg productive index (EPI), egg number, and hatchability (%) were lower in females treated with the NiO NPs than in control ticks. The toxicity of the NiO NPs on laboratory animals was also investigated using Swiss albino mice by oral dose of 500 mg/kg/day administration for five consecutive days. The hematological, biochemical, and histopathological changes were evaluated. The hematological analysis showed significant increase in the level of white blood cells (WBC) and hemoglobin (Hb). Biochemical analysis showed non-significant decrease in alkaline phosphatase (ALP) and alanine amino transferase (ALT). We concluded that NiO NPs have a significant acaricidal activity as demonstrated on eggs, larvae, engorged nymphs, and fully fed females of H. dromedarii. From a toxicological point of view further in vivo investigations are needed to determine the mechanism of toxic effect of NiO NPs.

Testicular transcriptome analysis under the dietary inclusion of l-carnitine reveals potential key genes associated with oxidative defense and the semen quality factor in aging roosters.

l-carnitine (LC) has been widely studied as a natural antioxidant molecule for treating low-fertility gametes. However, the molecular mechanism of the effect of LC supplementation on the testes of aging cocks has not been evaluated. Therefore, the objective of this study was to reveal the mechanism of testicular oxidative defense induced by LC supplementation in relation to the semen quality factor (SQF) in the aging cock through a transcriptome study conducted from a new perspective. A total of 24 Jinghong cocks at 55 wk of age were randomly divided into 2 groups (n = 12). All cocks were fed a standard isocaloric and isonitrogenic breeder diet (control, LC-0), and the other group was supplemented with LC at 150 mg/kg/d (treated, LC-150) for 12 wk. Remarkably, seminal characteristics and enzymes, sex hormones, and cock fertility related to testicular oxidative defense were considerably improved by LC supplementation. LC-150 testes showed the differential upregulation and downregulation of 97 and 90 transcripts, respectively, compared with LC-0 testes. Most upregulated transcripts were involved in testicular oxidative defense and spermiogenesis optimization, whereas the downregulated genes were responsible for oxidative stress, in contrast to the SQF. Functional analysis of the transcriptionally altered genes indicated the testicular deregulation of long-chain fatty acid and lipid peroxidation, enhancing fatty acid breakdown to release ATP production via ß-oxidation. These findings could lay the foundation for the discovery of new molecular markers of SQF-associated LC supplementation and potential targets for therapeutic intervention to optimize fertility in aging cocks.

Absorbable antibiotic beads as an adjuvant therapy in treating ventricular assist devices driveline infection: A case report.

BACKGROUND: Ventricular assist devices driveline infections are common, recalcitrant, and carry high morbidity and mortality. Herein, we reported a patient with driveline infection that was successfully treated with a combination of systemic antibiotics, surgical debridement, and instillation of absorbable antibiotic beads to the wound bed. METHODS AND RESULTS: A 39-year-old man with nonischemic cardiomyopathy underwent insertion of a continuous flow left ventricular assist device. Four years postoperatively, the patient presented with clinical, laboratory, and radiologic signs of driveline tract infection. He underwent extensive surgical debridement, installation of absorbable antibiotic beads that consisted of calcium sulfate, vancomycin, and tobramycin, into the wound bed, and systemic antibiotics. The patient was free of infection 9 month postoperatively. CONCLUSION: Absorbable calcium sulfate antibiotic beads may serve as a beneficial adjunct to surgical debridement and systemic antibiotics for the treatment of ventricular assist device driveline infection, and merit further investigation.

In vitro acaricidal effect of Melia azedarach and Artemisia herba-alba extracts on Hyalomma dromedarii (Acari: Ixodidae): embryonated eggs and engorged nymphs.

The present study aimed to evaluate the in vitro efficacy of four medicinal plant extracts: petroleum ether and ethyl alcohol extracts of the ripen fruits of Melia azedarach and whole aerial parts of Artemisia herba-alba against the two inactive stages of the camel tick Hyalomma dromedarii, embryonated eggs and engorged nymphs in comparison to reference acaricide Butox®5.0 (Deltamethrin). Egg and nymphal immersion tests at four concentrations with three replicates were used. The deformity in larvae hatched from treated eggs and adults moulted from treated nymphs were observed and photographed by light microscope (LM) and scanning electron microscope (SEM). The results showed that M. azedarach and A. herba-alba extracts revealed higher significant toxic effects on embryonated eggs and engorged nymphs comparing with the reference acaricide (Butox®5.0) and control. In egg emmersion test, the LC50 of petroleum ether extracts of M. azedarach and A. herba-alba was 3.14 and 3.91%, respectively and LC50 of the respective ethyl alcohol extracts was 1.77 and 2.45%. In nymphal immersion test, LC50 of petroleum ether extracts of M. azedarach and A. herba-alba was 0.26 and 1%, respectively, and LC50 of the respective ethyl alcohol extracts was 4.17 and 8.7%. Abnormalities were observed by LM and SEM in the larvae hatched from the treated eggs as incomplete development of legs and mouth parts as well as shrinkage mainly in legs and mouthparts of adults emerged from treated nymphs. In conclusion, all extracts and petroleum ether extracts of the two plants have great potential to be developed as a novel acaricidal for controlling eggs and nymphs of H. dromedarii, respectively.

An Approach to Treatment of Liver Cancer by Novel Glycyrrhizin Derivative.

BACKGROUND: Liver cancer is a life threating disease as it is the fifth most common cancer and the third most common cause of death worldwide with no safe, efficient, and economic drug available for treatment. METHODS: This study intended to investigate glycyrrhizin and its derivatives for possible use as a cytotoxic agent and as a drug for liver cancer treatment. Thus, after treatment of liver cancer cell line HepG-2 with 50 µM of each compound, cell viability was determined. RESULTS: The cytotoxicity assay showed glycyrrhizin derivatives ME-GA (18ß-Glycyrrhetinic-30-methyl ester) and AKBA (3-acetyl-11- keto-ß-Boswellic acid) to be the most potent drug against liver cancer cell line HepG-2 with IC50 values 25.50 ± 1.06 and 19.73 ± 0.89 µM, respectively. Both the compounds showed higher selectivity towards hepatocellular carcinoma rather than the normal lung fibroblast cell line WI-38. The presence of methyl ester at C-30 greatly increased the cytotoxicity of ME-GA which might be attributed to its higher activity and selectivity. Both ME-GA and AKBA contributed to inhibit cancer cell migration in the wound healing assay and impeded colony formation. The use of flow cytometry to carry out cell cycle analysis and the determination of possible mechanisms of action for apoptosis revealed that ME-GA arrested the cell cycle at G2/M that led to the inhibition of hepatocellular carcinoma and induced apoptosis via the extrinsic pathway and its ability to increase p53 transactivation. CONCLUSION: This work highlights the cytotoxicity of glycyrrhizin and its derivatives for possible use as a chemotherapeutic agent against hepatocellular carcinoma cells HepG-2. The most cytotoxic compound was ME-GA (18ß-Glycyrrhetinic-30-methyl ester) with no cytotoxic effect on the normal cell line. In summary, this new derivative may be used as an alternative or complementary medicine for liver cancer.

Antiviral Activity of Peanut (Arachis hypogaea L.) Skin Extract Against Human Influenza Viruses.

The high propensity of influenza viruses to develop resistance to antiviral drugs necessitates the continuing search for new therapeutics. Peanut skins, which are low-value byproducts of the peanut industry, are known to contain high levels of polyphenols. In this study, we investigated the antiviral activity of ethanol extracts of peanut skins against various influenza viruses using cell-based assays. Extracts with a higher polyphenol content exhibited higher antiviral activities, suggesting that the active components are the polyphenols. An extract prepared from roasted peanut skins effectively inhibited the replication of influenza virus A/WSN/33 with a half maximal inhibitory concentration of 1.3 µg/mL. Plaque assay results suggested that the extract inhibits the early replication stages of the influenza virus. It demonstrated activity against both influenza type A and type B viruses. Notably, the extract exhibited a potent activity against a clinical isolate of the 2009 H1N1 pandemic, which had reduced sensitivity to oseltamivir. Moreover, a combination of peanut skin extract with the anti-influenza drugs, oseltamivir and amantadine, synergistically increased their antiviral activity. These data demonstrate the potential application of peanut skin extract in the development of new therapeutic options for influenza management.

International Continence Society best practice statement for use of sacral neuromodulation.

AIMS: Sacral neuromodulation (SNM) is an accepted therapy for a variety of conditions. However, despite over 20 years of experience, it remains a specialized procedure with a number of subtleties. Here we present the recommendations issued from the International Continence Society (ICS) SNM Consensus Panel. METHODS: Under the auspices of the ICS, eight urologists, three colorectal surgeons and two urogynecologists, covering a wide breadth of geographic and specialty interest representation, met in January 2017 to discuss best practices for neuromodulation. Suggestions for statements were submitted in advance and specific topics were assigned to committee members, who prepared and presented supporting data to the group, at which time each topic was discussed in depth. Best practice statements were formulated based on available data. This document was then circulated to multiple external reviewers after which final edits were made and approved by the group. RESULTS: The present recommendations, based on the most relevant data available in the literature, as well as expert opinion, address a variety of specific and at times problematic issues associated with SNM. These include the use of SNM for a variety of underlying conditions, need for pre-procedural testing, use of staged versus single-stage procedures, screening for success during the trial phase, ideal anesthesia, device implantation, post-procedural management, trouble-shooting loss of device function, and future directions for research. CONCLUSIONS: These guidelines undoubtedly constitute a reference document, which will help urologists, gynecologists, and colorectal surgeons optimize their use of SNM for refractory urinary urgency and frequency, UUI, NOR, and FI.

Does Psychological Disturbance Predict Explantation in Successful Pelvic Neuromodulation Treatment for Bladder Dysfunction? A Short Series.

INTRODUCTION: Sacral neuromodulation (SNM) is a safe and effective therapy for patients with lower urinary tract dysfunction (LUTD). It is used in patients who have exhausted conservative and first line therapeutic options. The selection of eligible candidates could predict a successful therapeutic outcome. Although many factors have been identified, psychological/psychiatric disturbances are neither well understood nor are routinely evaluated prior to implantation. CASE REPORTS: We report three cases where identified psychological/psychiatric disturbances post-implantation could have influenced explantation in an otherwise successful implantation of SNM device assessed both subjectively and objectively. The device had to be explanted in two of the three. One more patient has requested but has not-yet undergone explantation and is receiving treatment for severe depression. One of the explanted cases has successfully undergone re-implantation after successful treatment of her diagnosed psychological condition, while the other's request for re-implantation has not yet been fulfilled. CONCLUSIONS: Psychological/psychiatric disturbance have possibly affected the treatment outcome and explantation of SNM in our patients despite a high success in resolution of the urinary symptoms. Addressing such disturbances when determining patient eligibility for SNM therapy could reduce the explantation rate after a successful therapeutic response, and is an interesting point of interest for future research into predictors of successful SNM implantation and therapy.

Effect of Goat's Milk Supplementation with Tamr on Free Fatty Acids, Antioxidant Activity, and Probiotic Bacteria of Bio-Rayeb Milk.

Tamr (dried dates) has a high sugar content, essential vitamins, and high nutrient density. Dairy products still are the most typical carriers of probiotic bacteria. Six treatments of bio-rayeb milk were manufactured from goat's milk fortified with 5%, 10%, 15%, 20%, and 25% Tamr using ABT-5 culture. Rayeb milk containing tamr had lower pH and fat and higher carbohydrate, total solids, dietary fiber, ash, total protein, water-soluble nitrogen, and total volatile fatty acids. Mixing tamr with bio-rayeb milk increased nutritional value by decreasing saturated fatty acids and increasing unsaturated fatty acids, oleic, linoleic, α-linolenic acids, and antioxidant activity values. The greatest counts of probiotic bacteria (L. acidophilus and Bifidobacterium) were detected in tamr rayeb milk, which increased the healthy value. The recommended level of bifidobacteria as a probiotic (107 cfu g-1) was exceeded for treatments of tamr rayeb milk and remained above 107 cfu g-1 until the end of storage. Adding 10% or 15% tamr to goat's milk highly improved the sensory properties of rayeb milk.

Cytotoxic new furoquinoline alkaloid isolated from Ammi majus L. growing in Egypt.

Two alkaloids of the furoquinoline-type were isolated from Ammi majus L.; a new one and was identified as 4-hydro-7-hydroxy-8-methoxyfuroquinoline (1), and the other was isolated for the second time from nature and was identified as 4-hydro-7-hydroxy-8-prenyloxyfuroquinoline (2). The structures of the isolated compounds were established and confirmed by 1D and 2D NMR spectroscopy including 1H, 13C NMR, COSY, HSQC and HMBC, while the exact masses were confirmed by HRESI/MS. The cytotoxic activity of the isolated compounds (1 and 2) was evaluated against HepG-2, PC-3, A-549 and MCF-7 and the obtained results suggested selective antiproliferative and cytotoxic effects, with IC50 = 230.2 and 326.5 µM against HepG-2 and MCF-7, respectively, for compound (1). While, compound (2) recorded IC50 = 234.2 µM against MCF-7.

THE EFFICACY OF THREE MEDICINAL PLANTS; GARLIC, GINGER AND MIRAZID AND A CHEMICAL DRUG METRONIDAZOLE AGAINST CRYPTOSPORIDIUM PARVUM: II-HISTOLOGICAL CHANGES.

Cryptosporidiosis parvum is a zoonotic protozoan parasite infects intestinal epithelial cells of man and animals causing a major health problem. This study was oriented to evaluate the protective and curative capacity of garlic, ginger and mirazid in comparison with metronidazole drug (commercially known) against Cryptosporidium in experimental mice. Male Swiss Albino mice experimentally infected with C. parvum were treated with medicinal plants extracts (Ginger, Mirazid, and Garlic) as compared to chemical drug Metronidazole. Importantly, C. parvum-infected mice treated with ginger, Mirazid, garlic and metronidazole showed a complete elimination in shedding oocysts by 9th day PI. The reduction and elimination of shedding oocysts in response to the treatments might be attributable to a direct effect on parasite growth in intestines, sexual phases production and/or the formation of oocysts. The results were evaluated histopathological examination of ideum section of control mice (uninfected, untreated) displayed normal architecture of the villi. Examiination of infected mice ileum section (infected, untreated) displayed histopathological alterations from uninfected groups. Examination of ileum section prepared from mice treated with garlic, ginger, mirazid, and metronidazole displayed histopathological alterations from that of the control groups, and showed marked histologic correction in the pattern with the four regimes used in comparison to control mice. Garlic successfully eradicated oocysts of infected mice from stool and intestine. Supplementation of ginger to infected mice markedly corrected elevation in the inflammatory risk factors and implied its potential antioxidant, anti-inflammatory and immunomodulatory capabilities. Infected mice treated with ginger, mirazid, garlic and metronidazole showed significant symptomatic improvements during treatment.

Significance of serum levels of vitamin D and some related minerals in breast cancer patients.

UNLABELLED: Vitamin D and calcium are involved in a wide range of proliferation, apoptosis and cell signaling activities in the body. Suboptimal concentrations may lead to cancer development. The role of phosphate in cancer metabolism is particularly relevant in breast cancer while, magnesium deficiency favors DNA mutations leading to carcinogenesis. OBJECTIVES: To determine serum levels of vitamin D, calcium, phosphorus, magnesium, and parathormone in female breast cancer patients and to assess their association with some prognostic factors in breast cancer. DESIGN AND METHODS: This study is done on 98 newly diagnosed female breast cancer patients and 49 age matched apparently healthy female volunteers as controls. Serum samples from all patients and controls were subjected to 25-OH Vit D, calcium, phosphorus, magnesium, and parathormone measurements. RESULTS: In the breast cancer group, the median serum levels of 25-OH Vit D were 15 ng/ml, while it was 21 ng/ml in the control group. Levels of 25-OH Vit D and other tested minerals were significantly lower while calcium:magnesium (Ca:Mg) ratio, and calcium:phosphorus (Ca:P) ratio were significantly higher in the breast cancer group. Significant negative correlation was detected between phosphorus and calcium, ionized calcium , calcium magnesium ratio, and calcium phosphorus ratio. CONCLUSION: It is not only the deficient levels of Vit D and other related minerals, but the combination of the abnormal levels of all the studied parameters that might contribute to the development of cancer. Further studies with larger number of patient are needed.

Inferior hypogastric plexus blockade versus acupuncture for the management of idiopathic chronic pelvic pain: A randomized clinical trial.

BACKGROUND: To compare the clinical efficacies of inferior hypogastric plexus blockade and acupuncture in the management of idiopathic chronic pelvic pain (CPP). METHODS: The study included 117 patients with CPP. Group 1 included 62 patients who underwent inferior hypogastric plexus blockade and group 2 included 55 patients who underwent acupuncture. Pain level was assessed using a visual analogue scale (VAS) immediately and at 2, 6, and 12 weeks after treatment. RESULTS: The preprocedure VAS score was 7.6 ± 0.15 in group 1 and 7.7 ± 0.24 in group 2 (p > 0.05). Pelvic pain decreased significantly in both groups after treatment, with pretreatment and posttreatment scores of 7.6 ± 0.15 and 2.2 ± 0.88, respectively, in group 1 (p < 0.0001) and 7.7 ± 0.24 and 4.7 ± 0.11, respectively, in group 2 (p < 0.0001). However, the decrease in pain scores throughout the clinical follow-up was significantly more in group 1 than in group 2 (p< 0.0001). Complete disappearance of symptoms was achieved in 72.6% of patients in group 1 compared to 54.5% of patients in group 2 (p = 0.3737). Patients who did not benefit from the treatment were significantly more in group 2 than in group 1 (25.5% vs. 6.5%, p = 0.0294). No complications were reported in both groups. CONCLUSION: The study results showed that inferior hypogastric blockade had a 72.6% success rate and showed a significantly higher effect on reducing pain intensity in a short period of time in the management of CPP, compared to acupuncture.

THE EFFICACY OF THREE MEDICINAL PLANTS: GARLIC, GINGER AND MIRAZID AND A CHEMICAL DRUG METRONIDAZOLE AGAINST CRYPTOSPORIDIUM PARVUM. I-IMMUNOLOGICAL RESPONSE.

Cryptosporidisis parvum is a zoonotic protozoan parasite infects intestinal epithelial cells causing a major health problem for man and animals. Experimentally the immunologic mediated elimination of C. parvum requires CD4+ T cells and IFN-gamma. But, the innate immune responses also have a significant protective role in both man and animals. the mucosal immune response to C. parvum in C57BL/6 neonatal and GKO mice shows a concomitant Thl and Th2 cytokine mRNA expression, with a crucial role for IFN-gamma in the resolution of the infection. NK cells and IFN-gamma have been shown to be important components in immunity in T and B cell-deficient mice, but IFN-gamma-dependent resistance is demonstrated in alymphocytic mice. Epithelial cells may play a vital role in immunity as once infected these cells have increased expression of inflammatory chemokines and cytokines and demonstrate anti-infection killing mechanisms. C. parvum immunological response was used to evaluate the efficacy of anti-cryptosporidisis agents of Garlic, Ginger, Mirazid and Metronidazole in experimentally infected mice.

Radioprotective effect of Curcuma longa extract on γ-irradiation-induced oxidative stress in rats.

This study was conducted to evaluate the modulatory effect of aqueous extract of Curcuma longa (L.) against γ-irradiation (GR), which induces biochemical disorders in male rats. The sublethal dose of GR was determined in primary hepatocytes. Also, the effect of C. longa extract was examined for its activity against GR. In rats, C. longa extract was administered daily (200 mg/kg body mass) for 21 days before, and 7 days after GR exposure (6.5 Gy). The lipid profile and antioxidant status, as well as levels of transaminases, interleukin-6 (IL-6), and tumour necrosis factor α (TNFα) were assessed. The results showed that in hepatocytes, the aqueous extract exhibited radioprotective activity against exposure to GR. Exposure of untreated rats to GR resulted in transaminase disorders, lipid abnormalities, elevation of lipid peroxidation, trace element alterations, release of IL-6 and TNF, and decrease in glutathione and protein level of superoxide dismutase-1 (SOD-1) and peroxiredoxin-1 (PRDX-1). However, treatment of rats with this extract before and after GR exposure improved antioxidant status and minimized the radiation-induced increase in inflammatory cytokines. Changes occurred in the tissue levels of trace elements, and the protein levels of SOD-1 and PRDX-1 were also modulated by C. longa extract. Overall, C. longa exerted a beneficial radioprotective effect against radiation-induced oxidative stress in male rats by alleviating pathological disorders and modulating antioxidant enzymes.

Anti-HIV-1 and cytotoxicity of the alkaloids of Erythrina abyssinica Lam. growing in Sudan.

Erythrina abyssinica Lam. is an important medicinal plant growing in Sudan; its seeds were investigated for the first time for their alkaloidal constituents and biological activity. The in vitro cytotoxicity of the crude alkaloidal fraction (CAF) against the cell lines HeLa, Hep-G2, HEP-2, HCT116, MCF-7 and HFB4 showed promising activity, with IC50 values of 13.8, 10.1, 8.16, 13.9, 11.4 and 12.2 µg mL⁻¹, respectively. Doxorubicin (positive control) showed in vitro cytotoxic activity with IC50 values 3.64, 4.57, 4.89, 3.74, 2.97 and 3.96 µg mL⁻¹, respectively. Bioassay-guided fractionation and isolation of the CAF led to the isolation of five Erythrina alkaloids, identified as erythraline, erysodine, erysotrine, 8-oxoerythraline and 11-methoxyerysodine. These were evaluated for their in vitro cytotoxic activity against Hep-G2 which resulted in IC50 values 17.60, 11.80, 15.80, 3.89 and 11.40 µg mL⁻¹, respectively. Furthermore, in vitro cytotoxic activity against HEP-2 was evaluated, which resulted in IC50 values 15.90, 19.90, 21.60, 18.50 and 11.50 µg mL⁻¹, respectively. The CAF caused a reduction in the viability of mock-infected MT-4 cells with a CC50 of 53 µM and a 50% protection of MT-4 cells against HIV-1 induced cytopathogeneticy with a EC50 of >53 µM, compared with EFV as a positive control, which had a CC50 of 45 µM and an EC50 of 0.003 µM. We concluded that the isolated alkaloids were responsible for the anti-carcinogenic [corrected] actions of the plant extract previously reported in the literature.
