Introduction: Nitrofurantoin (NFT) is abroad spectrum bactericidal antibiotic. The bioavailability of NFT is affected by many factors. Samafurantin® tablets containing 50 mg NFT were manufactured by Samarra drug industry. Urinary excretion studies were employed since; the urinary tract is the main site of NFT action and excretion. Objective: The objective of the study was to investigate the effect of Uricol® and food on secondary pharmacokinetic parameters of Samafurantin® tablets with different doses by applying urinary data. Methods: Twelve healthy male volunteers participated in this study. Urine samples were collected from each volunteer after overnight fasting at a specified time intervals which considered as a blank sample for measuring urine pH of urine. After that, volunteers were randomly divided into two groups (G1 and G2) each of six. Group 1 was administered 100 mg of NFT (Two tablets of 50 mg Samafurantin®) while, G2 was administered 200 mg of NFT (Four tablets of 50 mg Samafurantin®) as a single oral dose. Both groups administered the dose on an empty stomach (fasting), along with one Uricol® of 5 g sachet on fasting, and on full stomach after eating a standard breakfast after 1-week washout period between each experiment and another. For each experiment, urine samples were collected from each volunteer from 0.25 to 7 h post dosing. In addition, the volume of each void urine sample was measured. Results: Both groups (G1 and G2) showed only slight differences in the pH of urine after administration of Samafurantin® as compared with that of the blank. While, the pH of urine for both groups was higher after administration of Samafurantin® tablets along with Uricol® 5 g. In both groups, each of Uricol® and food exhibited no significant differences (P < 0.05) in secondary pharmacokinetic parameters of NFT; the rate constant of elimination (Kel) and absorption (Ka) and consequently their half-life (t0.5 el and t0.5 abs) as long as the drug followed first-order kinetics. While significant differences (P < 0.05) were observed for maximum excretion rate (ExRmax), cumulative amount excreted in urine (CAe) and CAe as percentage of the dose. This could be attributed to the pH-change of urine by Uricol® which alkalinized the urinary and kidney tract or delaying gastric emptying by food. Same observations were attained when comparing G1 with G2 after administration of NFT on fasting. Conclusions: Administration of Samafurantin® tablets at higher doses, along with Uricol® or with food increases secondary pharmacokinetic parameters related to the rate and extent of absorption and elimination without significant changes in their corresponding rate constants and half-lives. © 2018 Drug Invention Today.
This study was conducted in Baghdad, Iraq from December 2021 to May 2022. The goal was to determine the effect of Toxoplasma gondii on liver function by examining the relationship between Toxoplasma infection and hormones. One hundred and twenty male patients with Chronic liver disease (CLD) (age:14-75 years) and 120 control males (age: 24-70 years) participated in this study. Serum samples were taken from all individuals and were then analysed for anti-Toxoplasma antibodies. Hormonal tests were conducted for all participants which included (Cortisol, testosterone, prolactin, insulin, and thyroid-stimulating hormone TSH). Biochemical tests included (Prothrombin time PT, international normalized ratio INR and albumin); liver enzymes

Show MoreAim: The aim of this study is to determine the correlation between levels of certain seminal biochemical parameters and serum reproductive hormones, on the one hand, and sperm function tests, on the other hand, in asthenospermic patients. Patients and Methods: Sixty asthenospermic patients and twenty fertile men as a control group were included in this study. Semen samples were collected to perform seminal fluid analysis. Total protein, cholesterol, calcium, creatine kinase, and fructose were measured in the seminal plasma. Blood samples were collected for hormonal assay of serum reproductive hormones: testosterone, prolactin, luteinizing hormone, and follicle-stimulating hormone. Results: The results revealed a significant positive correla

So this study was done to assess diametral tensile strength and microhardness of glass ionomer reinforced by different amounts of hydroxyapatite. Materials and methods: In this study a hydroxyapatite material was added to glass monomer cement at different ratios: 10%, 15%, 20%, 25% and 30% (by weight). The diametral tensile strength test described by the British standard specification for zinc polycarboxylate cement was used in this study and the microhardness test was performed using Vickers microhardness testing machine and the microhardness values were calculated and statistical c

Show MoreFour hundred and fifty urine samples were collected from patients suffering from urinary tract infection from the General Azadi hospital in Kurkuk province ,during the period of october 2007 till march 2008 . Results of bacteriological culture revealed that (168) out of (450) studied samples (37.3%) gave positive culture using blood agar and macConkey agar ; different species of bacterial isolates were detected using morphological and biochemical tests ,from these isolates the highest percentage of the isolates were from Escherichia coli when it was (100) isolates out of (190) isolate (52.63%) . one hundred isolates were distributed between (77) from females and (23) from

Show MoreUrinary tract infections (UTI) are some of the most common infections experienced by humans, exceeded in frequency among ambulatory patient only by respiratory and gastrointestinal infections. It is also the most common cause of nosocomial infection in adults. A total of three hundred urine sample were collected in age (1-69 years old) in both gender, with (UTI) symptoms referred to AL-Yarmok Teaching Hospital at Baghdad city during the period from January 2010 till August 2010. The commonest isolates were Escherichia coli (E.Coli), Proteus mirabilis and Klebsiella pneumoniae (These represented 49.2%, 22 %, and16 % of isolates respectively).

This work aims to emphasize the effect of cement filling on the mechanical parameters, thermal stability, and wettability of acrylic polymer. The preparation was carried out using the casting method from acrylic polymer coating solution, which was added to cement nanoparticles (65 nm) with weight concentrations of (0, 1, 2, 4, and 8 wt%) to achieve high-quality specifications and good adhesion. Maximum impact strength and Hardness shore A were observed at cement ratios of 2 wt% and 4 wt%, respectively. Changing the filling ratio has a significant effect on the strain of the nanocomposites. The contact angle was i
