Kidneys are vital organ involved in the elimination of waste and toxins from the body and maintenance of homeostasis among other functions. Following the entrance of pathogen or xenobiotics into the body, the immune system respond and in most instances, this responses are out of proportion due to release of pro-inflamatory cytokines and the hyper response of the immune system may end up attacking certain organs of the body and hence, altering the physio-biochemical role of such organ. This study investigated the effect of some natural products commonly used in the management of hepatitis and it associated biochemical alterations on other key systems of the body. Albino Wistar rats weighing 60 to 120g were used for this study. The animals were divided into seven (7) groups of five (5) animals each. Group 1 served as the normal control and were not induced while animal in group 2 to 7 were all induced for Hepatocellular carcinoma using CCl4. Group 2 served as positive control and where not treated while animals in group 3 to 7 received various forms of naturopathic remedy as treatment; Ganoderma lucidium, Astaxanthin, Liv 52 Hb, STC30 and combination of all the remedies respectively. The treatment lasted for a period of three weeks (21 days). Twelve (12) hours after last treatment, the animals where sacrifice under chloroform anesthesia and blood samples collected via cardiac puncture. The blood samples were centrifuge at 4000rpm for 10 minutes to obtain the serum. The serum was separated and used for the estimation of serum electrolytes, urea and creatinine to examine the renal functions. Results of the investigation showed that; the serum urea concentration in group III (6.64±0.27), V (3.88±0.15), VI (3.66±0.12) and VII (3.80±0.22) where significantly (p≤0.05) decreased compared to group II (7.16±0.18) the positive control. Similar trend was also observed for serum creatinine. Serum electrolytes concentration; Na+,  K+, Cl- and HCO3- recorded  slight varying degrees of changes across all treated groups at p≤0.05 compares to the positive and normal control. From our results, HCC induced animals treated with Ganoderma lucidium, STC30, Liv 52 Hb and combined treatment showed varying degree of renal function improvement by improving glomerular filtration rate (GFR). The reduction in GFR can be observed in the positive control group as presented by it many abnormal renal parameters’ values which is indicative of renal failure and poor GFR. Administration of these natural products however, caused an observed initiation of renormalization in the values of some of the renal parameters with most of the treated groups having values that are significantly different from those of the positive control group at p≤0.05 which was not treated after induction of HCC. It may thus be concluded that the treatments used had positive effects on the Glomerular filtration rate which led to improve values of some of the renal parameters in the groups treated with these natural products.

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as positive control group (canals prepared but unfilled). The remaining 45 roots were randomly divided into three experimental groups (n=15root/group) and obturated with the following procedures: in group 1, glass ionomer-based sealer and cone (ActiV GP obturation system); in group 2, bioceramic sealer and cone (EndoSequence BC obturation system); and in group 3, roots were filled with bioceramic sealer and cone (Smartpaste bio obturation system). All specimens were tested in a universal testing machine for measuring fracture resistance. For each root, the force at the time of fracture was recorded in Newtons. The statistical analysis was performed by using Kruskal-Wallis and post hoc test. There were no significant differences between the three experimental groups. The fracture values of three experimental and negative control groups were significantly higher than the positive control group. Within the limitations of this study, all materials increased the fracture resistance of instrumented roots.

Methanol poisoning is a hazardous intoxication characterized by visual impairment and formic acidemia. The therapy for methanol poisoning is alcohol dehydrogenase (ADH) inhibitors to prevent formate accumulation. Ranitidine has been considered to be an inhibitor of both gastric alcohol and hepatic aldehyde dehydrogenase enzymes. This study aimed at testing ranitidine as an antidote for methanol acute toxicity and comparing it with ethanol and 4-methyl pyrazole (4-MP). This study was conducted on 48 Sprague-Dawley rats, divided into 6 groups, with 8 rats in each group (one negative control group [C1], two positive control groups [C2, C3] and three test groups [1, 2 and 3]). C2, C3 and all test groups were exposed to nitrous oxide by inhalation, then, C3 group was given methanol (3 g/kg orally). The three test groups 1, 2 and 3 were given ethanol (0.5 g/kg orally), 4-MP (15 mg/kg intraperitoneally) and ranitidine (30 mg/kg intraperitoneally), respectively, 4 hours after giving methanol. Rats were sacrificed and heparinized, cardiac blood samples were collected for blood pH and bicarbonate. Non-heparinized blood samples were collected for formate levels by high performance liquid chromatography. Eye balls were enucleated for histological examination of the retina. Ranitidine corrected metabolic acidosis (p = .025), decreased formate levels (p = .014) and improved the histological findings in the retina induced by acute methanol toxicity.

Study design: Four groups, between-subjects study. Objectives: To investigate the effects of exercise on adaptation of normal subjects who had been artificially spatially disoriented. Background: Many patients referred for rehabilitation experience sensory changes, due to age or disease processes, and these changes affect motor skill. The best way to train patients to adapt to these changes and to improve their sensorimotor skills is unclear. Using normal subjects, we tested the hypothesis that active, planned head movement is needed to adapt to modified visual input. Methods and measures: Eighty male and female subjects who had normal balance on computerized dynamic posturography (CDP) and the dynamic gait index (DGI), were randomly assigned to four groups. All groups donned diagonally shift lenses and were again assessed with CDP and DGI. The four groups were then treated for 20 min. Group 1 (control group) viewed a video, Group 2 performed exercise that involved translating the entire body through space, but without separate, volitional head movement, Group 3 performed exercises which all incorporated volitional, planned head rotations, and Group 4 performed exercises that involved translating the body (as in Group 2) and incorporated volitional, planned head motion (as in Group 3). All subjects were post-tested with CDP and DGI, lenses were removed, and subjects were retested again with CDP and DGI. Results: The groups did not differ significantly on CDP scores but Groups 3 and 4 had significantly better DGI scores than Groups 1 and 2. Conclusions: Active head movement that is specifically planned as part of the exercise is more effective than passive attention or head movements that are not consciously planned, for adapting to sensorimotor change when it incorporates active use of the changed sensory modality, in this case head motion.

Background: We investigated whether the frequency of lower urinary tract symptoms (LUTS) increased in patients in whom double-J stents were applied. We also evaluated several medical therapy protocols to treat symptoms related with ureteral stents.Materials and Methods: A total of 108 patients, in whom unilateral double-j stent was applied during ureteral stone treatment, were included. Before the double-J stent was applied, all patients completed storage components of the “International Prostate Symptom Score” (IPSSs), quality of life components of the IPSS (IPSS-QOL) and “Overactive Bladder Questionnaire” (OABq) forms and scores were calculated. After the procedure, cases were randomized into 5 groups, an antiinflammatory was given to Group 1, spasmolytic to Group 2, anticholinergic to Group 3 and α-blocker to Group 4. No additional drug was given to Group 5 as this control group. During the fourth week of the procedure, IPSSs, IPSS-QOL and OABq forms were again completed and scores were compared with the previous ones.Results: When all the cases were evaluated, the IPSSs, IPSS-QOLand OABq scores of patients in whom the double-J stent was applied were statistically significantly higher the procedure. Compared to the control group, the cases where the double-J stent was applied showed a higher IPSSs, IPSS-QOL and OABq scores and none of the medical therapies could prevent this increase.Interpretation: The frequency of LUTS increased in cases where the ureteral stent was applied and discomfort continued as long as the stent stayed in the body.

Fly is one of the vectors of foodborne pathogenic vectors and causes myiasis in humans and animals. To prevent the contamination of food and myiasis, various chemical products are commonly used. However, eco-friendly is now a trend all over the world so natural products are the alternative ways to reduce the chemical residue in the environment. The present study was screened the 12 natural products in 4 groups; the essential oil plants, the alkaloid plants, the cyanogenic plant, and the inorganic compounds which use a simple extraction on the fly repelling and larvicide. The fly repelling efficacy with 2 criteria consist of the time of the first swarm and percent repelling (PR) in the first 15 min. The larvicidal efficacy was determined by the mortality rate within 24 h. The Kaffir lime peels aqueous crude extract exhibited the best result on fly repelling from both criteria with no significant difference. The bamboo shoots aqueous crude extract gave the best result on larvicide with significantly different from other groups (P < 0.001) which was faster than the positive control group (Coumaphos & Propoxur). Moreover, the high mortality rate reached 73.33 ± 15.28% within 24 h, higher than the positive control group. The present study indicates the power of common natural products on fly repellent and larvicide that may apply for fly repellant to reduce the food contamination especially fresh materials and prevention or treatment of animal and human myiasis in rural areas

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

Background: Pistacia atlantica kurdica has recently been shown to possess free radical scavenging ability. The current study aims to investigate the protective effect of this plant against cadmium-induced nephrotoxicity. Methods: Thirty-six rats were divided into 6 groups (6 in each), and treated as follows: group 1 received normal saline (control group), group 2 (positive control) received cadmium by drinking water (100 mg/ L/d), group 3 received 200 mg/kg of P. atlantica extract, and groups 4-6 received cadmium as well as 50, 100 and 200 mg/kg/d of P. atlantica extract (orally), respectively. After 2 weeks, oxidative damage and renal function markers were assayed by standard methods. Results: In cadmium group, a significant increase was observed in serum blood urea nitrogen (BUN) (P<0.01) and lipid peroxidation (LPO) level of renal tissue (P<0.001) and a remarkable decrease was found in total thiol molecules (TTM) of the kidney (P<0.001). Despite the decreased renal antioxidant capacity, these changes were not significant. P. atlantica extract improved the LPO, TTM, and histopathological changes in renal tissue. Conclusion: In this study, although the P. atlantica extract did not have a significant effect on cadmiuminduced renal dysfunction, it did improve the oxidative/antioxidant balance in renal tissue.

Blood samples of One hundred and twenty patients from different hospitals in Baghdad infected with hydatidosis in different sites of the body (Liver, Lung, multiorgans and kidney) were collected for this study. On the other hand, 30 healthy individuals were included as a control group. This study was conducted to evaluate the effect of this disease on the serum protein profile of the patients using electrophoresis. The results revealed four different protein banding patterns with difference in number of bands and their molecular weights in comparison to the control group, and these differences depended on the site of infection. However the data showed a presence of the same band in all patients with different site of infection.

Background and aim: Comparison of different irrigation and agitation methods for the removal of two types of calcium hydroxide medicaments from the root canal walls.Methods: Fifty extracted single rooted teeth were selected for this study. After decoronation, the root canals of these teeth were prepared to the size F3 (30 no.) using rotary ProTaper file system. These samples were randomly divided into four groups. Group 1 (n=20) were filled completely with water based calcium hydroxide (CH), Group 2 (n=20) were filled with oil based CH using lentulo spiral, Group 3 (n=5) - the positive control group received the CH as intracanal medication, but no subsequent removal, Group 4 (n=5) - the negative control did not receive CH placement. Further on, Group 1 and Group 2 were divided into four sub-groups (n=5). In sub-group A we performed conventional syringe irrigation with side-vented needle sub-group B) manual dynamic agitation, sub-group C sonic agitation using endoactivator, sub-group D passive ultrasonic irrigation (PUI). Roots were split longitudinally into mesial and distal halves. Digital images of the root canal walls were acquired by a Dental Operating Microscope (DOM) and assessed by using a scoring criteria at different thirds (coronal, middle and apical) of the root canal as follows: score 1, score 2, score 3, and score 4. Data were analyzed applying one-way analysis of variance (ANOVA) and Tukey’s multiple comparison tests at a 95% confidence interval (P < 0.05).Results: Statistically significant differences were not found between the experimental groups and the negative group in any one third of the root canal (P>0.05). However, a difference did exist between the experimental groups and the positive control group (P<0.05). None of the experimental groups totally removed CH substances from root canal walls.Conclusion: Among all experimental groups, removal of CH was best achieved by sonic agitation using endoactivator followed by passive ultrasonic irrigation (PUI), manual dynamic agitation and conventional syringe irrigation with side-vented needle.

The aim: To evaluate the effect of single daily 25 mg of spironolactone on serum electrolytes and kidney function tests in patients with severe chronic left sided heart failure. Materials and methods: 60 patients with severe chronic left sided heart failure were enrolled in this study and they were divided in to 2 equal groups’ one group with standard therapy of HF and the other with spironolactone in a dose of 25 mg / day, as an additive therapy to the standard one. Serum electrolytes and kidney function tests were assessed at the beginning of the study and after 3 months. Results: A significant increment in serum potassium (p<0.05) was observed in the spironolactone group after 3 months treatment, while no significant reduction in serum sodium (p>0.05) and no significant increase in serum creatinine and blood urea (p>0.05) was noticed in the same group, control group showed no significant changes (p>0.05), in both serum electrolytes (S.K and S.Na) and renal function tests (S.C and B.U). Conclusions: Spironolactone caused a significant elevation of serum potassium level but this elevation is still with the clinically accepted ranges when low dose of spironolactone is used and with intact renal function. Serum creatinine level was not significantly increased with 25 mgl day of spironolactone. We conclude that Renal function tests namely blood urea and serum Creatinine, and serum potassium should be closely monitored in patients on spironolactone therapy especially those patients who use ACEI and ARBs in addition.
